Suspension brief talk McPherson suspension

As independent suspension in said form of the highest rates of suspension, McPherson (U.S. MacPher-son Strut, Hong Kong Cantonese transliteration "MacPherson") are widely used in the field of civilian vehicles. McPherson Suspension named from its inventor "McPherson. McPherson, its structure is compact, efficient operation and become the visibility the highest form of front suspension, it is not the first to be invented form of independent suspension. The initial suspension systems with non-Unibody, that is, the girders frame. Be able to so easily suspension system-oriented institutions, as well as elastic elements all the double wishbone system is installed on top of the girders, is the emergence of the earliest and highest penetration rate (in fact, there is no other form of independent suspension, can reasonably beam-type frame with). With the Unibody was invented, the size of the car can be to a large extent to compact. The suspension system is also compact needs. McPherson suspension system concept, as the shock absorbers of the elastic element also served as steering, structural reinforcement, as well as pass the role of force and torque, which can simplify the guide mechanism, freeing up more space for the engine compartment.
McPherson suspension structure is quite simple: under the wishbone is the only guide mechanism components responsible for passing the vertical and horizontal forces, thus the lower wishbone shape similar to the double wishbone wishbone, are presented to the "A" shaped, in a complex environment force able to combine the strength in all directions; elastic element of shock absorbers and column at the same time to integrate the spring, shock absorption, as well as axial, lateral force structure, so the structure of the shock absorbers and column than other forms of shock absorbers wants more rugged, more visual stout. It should be emphasized that, "McPherson front suspension designed, it is a necessary condition for the shock machine column is also responsible for steering. The rear suspension structure similar to the Subaru Impreza (9 generations ago), can only be called "class McPherson.
MacPherson shock absorbers and column, one end with the steering gear the rigid fixed, the other end of that is on a fixed point, is installed in the top of the top of the tower we commonly known as "shock absorbers". On fixed point to take into account the rotation of the shock absorbers and column (with the rotating wheel) as well as to withstand the forces and moments. McPherson suspension "top", compared to the double wishbone or multi-link system, its design strength requirements are higher. Parenthetic digression for reinforcing the top of the tower strength, also derived from the horizontal struts called "top", around the top of the tower rigid connection, making the entire engine compartment of the original semi-open section to see from the front past a closed quadrangle, to eliminate the deformation of the ends overhead because of the force to the intermediate bent.
The McPherson suspension advantages of believe that many people are familiar with: compact structure, occupy less space; frame stress points less and less frame is designed to be simple by force; components, and low cost. The disadvantage is that the wheel moves up and down, the motion law of the main pin is determined by the geometric angle of the lower rocker arm, the trajectory is a single arc, and not by changing the constraint condition of the steering knuckle, to obtain the complex positioning parameter variation, so in motion and comfort, McPherson is not especially good. It can be said McPherson is the most moderate design, low cost, reliable work, but losing performance.

Figure: McPherson suspension, the BMW 5 Series, take up less space, so welcomed by the vast majority of the world's automobile manufacturers.

 This is a complete picture of the McPherson suspension lower arm connected to the lower half of the steering knuckle, shock absorber column is fixed in the upper part of the steering knuckle, steering tie rod control steering section with shock absorbers and column overall rotation.

Suspension briefly talk about the double wishbone suspension

The double wishbone suspension in the form known as double rocker, also according to the shape of the cross-arm, named the double A-arm or double wish bone. The double wishbone suspension, the English name "Double Wishbone", it really is a double wish bone. Double wishbone wishbone, in addition to the outside much like with the letter "A", and the similarity of "Wishbone" is more subtle. Birds animals such as chickens, ducks, a bone between the neck to the back, similar to the mammalian collarbone. After Thanksgiving dinner meal turkey, it will leave the root of the V-shaped bones, two people each carrying one end of it it snapping, we believe whose hands get larger half will wish come true, hence the name "the Wishbone. The shape of the bones, and is very similar to the wishbone, "Bones" and "rocker" function also has a subtle similarities, so they took this image of the "Double Wishbone" in the form of this suspension, but also give full expression to the name of its role.

Figure: on the left is the bird wishbone. Two hands each holding the the wishbone of one end of the break apart, and the right hand, a large part, to bring good luck.

Double wishbone has two generally "V"-shaped cross arm up and down arrangement. The force double wishbone suspension, vertical and horizontal lateral torque by double wishbone to pass, while the shock absorbers and column throughout the two cross arm in the middle of space, only need to take the cylinder direction along the shock machine axial force. Depending on the depot, the design of the different models, double wishbone morphology has a vastly different changes, such as the Honda Civic, rear double wishbone structure on the cross arm is a banana-shaped lower wishbone wishbone trailing arm "T"-shaped combination.

The double wishbone widely used in racing, precisely because of the show the advantages of the double wishbone, fully meet the system requirements of motorsport racing suspension. First, double-wishbone can be very simple to get the high strength of the structure, and less use of materials. Through the length of the wishbone, wishbone plane angle, the mutual distance of the upper and lower wishbone, and the relative position and angle adjustment, can adjust to different tire trajectory parameters such as braking kingpin angle to increase to inhibit bend forward steering the outside wheel tread should be as perpendicular to the road surface contact and so on. Uneven force the last double wishbone system of shock absorbers, and does not require such as McPherson generally strong tower, the favorite won the Formula One racing does not exist at the top of the tower, and it is easy to achieve pusher shock absorbers design, of course, it is unrealistic for the average civilian car. The downside, only the most obvious is the double wishbone need to occupy a larger body space, which rarely appear in compact models. Plus manufacturing costs relative to McPherson, double wishbone suspension become an advanced positioning symbol of sports performance.

Double cross arm is widely used in car racing and supercar, but once the double arm into high performance mark. But in fact there is no absolute suspension system performance, due to different design and adjustment, will have different properties.

Spring: recommended several essential maintenance

Spring flowers, to the most vibrant season of the year. You car fans and friends to enjoy the warm sunshine of spring genial, also must not forget to give your car to do a seasonal maintenance. The issue of fans the world "on the to recommend several essential maintenance method, a friend of the owners according to their own needs and choose the good and for the.
    
    Air-conditioned self-test and ultimately
   
    Early on the air conditioning in order to be able to successfully start the air conditioning in the summer to check if the issue should be repaired in a timely manner. Auto repair experts believe that the owners themselves to the limits of air conditioning refrigeration temperature sensing test, as long as the flat and normal temperature can be, if you go to a professional service station for inspection. General Automotive Air Conditioning limit refrigeration is relatively fixed, such as Toyota series of cars can reach 5 ℃ to 7 ° C, Jetta and other European cars can reach 4 ° C.
   
    To early closure glaze sealed plastic
   
    The spring Fengshahenda car splashes of small stones at high speeds as well as spring common insect body fluids will harm the paint. According to experts, the closure of the glaze automotive paint brightness and hardness are improved greatly, the cars can look. Sealed plastic chassis for the car to do, and can protect the chassis of the vehicle anti-collision, anti-corrosion effect, but also to isolate the noise to some extent. If it is a new car should carry out maintenance in advance.
   
    Interior disinfection is the most important thing
   
    The owners generally few windows in the winter of ventilation, the car has accumulated a large number of bacteria. Spring bacteria, viruses easy to breed, so this season the car a thorough disinfection is necessary. First of all, by the high-temperature steam to the corners of the air conditioning vents, seats, interior stains removed; manipulate units, doors and other parts to be cleaned and disinfected and then the dedicated interior cleaning agent. Remind owners to use neutral washing liquid washing and cleaning to be taken to avoid the sound, electrical equipment such as radios, CD influent and corrode.
   
    The need for timely replacement of air filter
   
    The car's air filter is equivalent to the human nose, the air entering the engine to go through the first hurdle, and its role is to filter out the sand as well as some of the suspended particulate matter in the air, so that the air entering the engine is relatively pure, so as to the engine is working properly. Spring air contains more dust and sand, air filter is prone to clogging, engine appears difficult to activate, unstable idle symptoms. General automotive air filter at 10,000 km conduct an inspection to be replaced every 20,000 km.
   
    Outing before major checks
   
    Auto repair experts remind you to check the brake system in the first spring outing before their first feel the braking system whether the abnormal reaction is sensitive. Check the tire above foreign objects or damaged, also check the tire wear indicator line, if you have ground to a marked line is necessary for timely replacement of the tire. The second is to listen to the car in motion, chassis and other parts of the abnormal sound, whether the oil spill, check the drive belt breaks, brake oil, transmission oil, motor oil, direction booster oil, antifreeze liquid The surface is normal, the need to replace the oil, water should be replaced in a timely manner.

The spring Zijia - Notes

Book your hotelBy car outing, can set the hotel through a travel agent or local friends, can also be set through the information network of online travel services, you can also bring your own tent. If you are a young man of fashion, like driving a saloon car to play, of course, did not have to take the booking of hotel, you can be chic Meimeideshui in the room in the car.
   Gather drugsTravel outside, and sometimes inevitable bumps, the car to have preparedness, the person must have some preparedness, so to bring essential drugs, such as bandages, Band-Aid, eliminationThe Travel Destinations Next stop: the space of outdoor adventure, love and hate New Caledonia paradise tour focusing poison the water of the well-known domestic enterprises, anti-inflammatory drugs, sunstroke, anti-motion sickness pills, gnats syrup. The disinfectant and gnats Potion to properly placed to prevent leakage of.
   An ample supply of LingchaoThe self-driving tour, tolls, bridge tolls, parking fees, anytime, anywhere to use the best an ample supply of less than $ 10 Lingchao do so both for their own convenience, but also facilitate the others.
   Carefully choose the gas stationShould choose the larger, refueling vehicles where more gas stations. All electronically controlled fuel injection engine vehicles, plus gasoline should pay more attention. Poor quality gasoline easy to damage the engine.
   Parking saferBy car on the way, parking is a need to pay special attention to, and usually do not often go, the routes are not familiar with, for the sake of convenience, casual chaos stopped on the roadside, easily lead car is stolen or detained. So, be sure to pay attention to the car in the parking handbrake tension hung up the block after flameout. Best to tune the front to the direction conducive to play and then go to avoid walking vehicles shift does not come out. If she needs to stop and no parking, best to leave personal belongings unattended in the car.
   Speed ​​not too fastOn the highway, we must note that the speed is not too fast. In inter-provincial national highway, overtaking, the car will be very frequent freight long-haul trucks to and from the national highway, the car who may be in a state of fatigue driving, we must be careful. Take the mountain should be especially careful. Too frequent braking, excessive use of the clutch, the gear is inappropriate and so likely to cause the failure of the vehicle, increase the likelihood of accidents.

Risk of wheel modified to avoid the cut tire hub

Eat tires, tire grinding these terms have become commonplace, but modifications "cut tire and understand how much? Select adapted wheels hub edge (rim) too thin sharp noticed? Sharp rimin the car at high speed, cornering, the impact force when the obstacle can directly cut a tire and unexpected, this is not alarmist, we need to address these issues, so as to avoid accidents.

What is a cut tire?

The cut tire generally appear in the case of the outside of the hub edge (rim) is relatively thin or rim unpolished blunting by impact rim and tire contact friction, directly to the tire according to the size of the impact force to the rim side cut or badly worn.
Today, the majority of car tires using the form of a tubeless tire, tire manufacturing start internal Finally, at the end of the edge of the wheel design. Problems due to the use of the tire tread directly in contact with the ground, and the car at the starting, braking will wear, so the tire surface are usually more durable than the other portion, but the sidewall in contact with the rim of the point is not the thickness of the tire surface, thus demonstrating more fragile.
The sidewall and the rim has a certain distance, and the The rim contact position is conducive to withstand the vicinity of the "special protective rubber" and "heel" of tire rim and tire friction. We look at the next diagram, has been located in the rim inside direct contact with the side of the rim and the tire replacement tires special protective rubber bead heel ", the exterior looks, the tread of the tire the the bead heel closer; If the impact of the sharp rim can be directly circulated closer to the outside of the tire and cause an accident.

The turbocharged engine oil choice

With a turbocharged engine is very common, and a fundamental change in the life of the turbocharger, correct maintenance, more than 200,000 kilometers without failure is also common.And most of the problems of a turbocharger because of seal damage between the turbocharger and the intake pipe, closed lax oil leakage into the combustion chamber. The main reason for the oil seal damage confined to the following points: First, the use does not match with the turbocharged engine oil, two oil change interval is too long, incorrect use.

These are lead to reasons turbocharger early damage. The turbocharged engine with a naturally aspirated engine lies in the speed and temperature. The so-called speed refers to the speed of the turbine shaft and bearing the full load capacity of up to of nearly 200,000 revolutions per minute, this high speed and temperature must be sufficient lubrication and cooling requirements of the bearing of the main shaft indoor.

Therefore, certain requirements for oil. A good abrasion resistance to high temperature, high film strength, shear and strong. Meet more than four points the best choice is a full synthetic oil or semi-synthetic oil. The higher the speed, the oil resistance to shear force, shear force is the protection of the oil viscosity stability. Only in this way can the lubricating ability of the oil at high speed does not drop. Fully synthetic motor oil is better than ordinary mineral oil, in particular, the advantages of the shear force is particularly prominent.

The best option is to fully synthetic oil or semi-synthetic motor oil, the higher the speed the stronger oil shear force

The ideal value of the Fox 2.0 direct injection engine fuel consumption report

Everybody was concerned about the fuel consumption of the new Fox, in particular, this 2.0 GDI direct injection engine performance and fuel consumption to

Updated daily fuel consumption report, with everyone looking forward to the fuel consumption down to the ideal value!

The first tank of fuel is No. 93. The future to look at the situation and then set whether to change 97.

My goal is: smooth ride into the 9, the intense driving into 10. Do not know the The new Fuk ability to force point!

Provide car factory fuel consumption values ​​of 1.5 months, this can be basically ignored:

300 Ocean 93 oil to fill up the car after 2.5 months after running after more than 70 kilometers fuel consumption performance: 100 km fuel consumption has been reduced to 13, with an average speed of 12 km / h.

4.5 morning, 159 km fuel consumption dropped to 11.2, with an average speed of 16 km / h:
5.5 months 9 at night, opened the 185 km, fuel consumption is reduced to 10.8, an average speed of 17 km / h:
In fact, this is the middle of twists and turns a lot of out of work in the morning, open air queuing idling release, probably waiting for over 20 minutes, the fuel consumption immediately rose to 11.2 from last night's 10.8, barely finishing things open back to the company to 11. Open home at night small block for a while, and to rise to 11.1. I also think that this car is basically only about 11 lingered for a while and cool ~ ~

Effectively prevent car rust oxidation

In damp summer, car maintenance has become a relative some headache.Due to the humidity of the air, and thus take care of the car paint and metal parts become particularly critical. Well, in this damp season, we should be the vehicle for proper protection it? Below introduce you to seven can effectively prevent the car from rust oxidation coup.

 Tip 1: alert to the subtle scars

Paint surface often rust, in addition to the common collision, scratching, driving tires bouncing small stones to play in the paint, but also make the flaking paint appears a small point, and over time will produce small rust spots. Which a small scar because mostly in humble at easily be overlooked. Therefore, usually to regularly check the body, engine cover and body around, if it is found necessary and timely to the professional beauty shop processing.

Tip 2: easy to water, ground investigation at the humidity

Vehicles on the way, encounter rain and snow, or passing through muddy puddles it is inevitable, the the underbody gap at the car floor, etc. are easily accumulated sludge owner is not cleaned in a timely manner, which makes moisture be hiding. Therefore, for the wheels inside and outside edge of the door, the bottom corner of the luggage door keyhole and wiper frame movable parts, etc., should always be checked at the same time to maintain the smooth flow of the drainage holes in the door and body ministries to check the car cover humidity, such as carpets and other floor member to prevent rust.

Tip 3: soft paint to do the sealing glaze

Some softer vehicle paint, sand particles hit the body of the vehicle in the process of high-speed driving may also resulting in relying marks of fine. For such vehicles, can give body to do sealing glaze, it can be a solid protective film to form a mesh, to improve the hardness of the paint, and the effect can be maintained for about one year. The coating can also achieve a similar role. In addition, the bottom of the vehicle can be armored chassis or sealed plastic chassis acid rain, so you can protect against corrosion, the original protective layer is not easy chapped, shedding, but also to prevent the impact of traveling among the pebbles on the chassis.
