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.
