“typical double-wishbone independent suspension structure of FIG.”
double-wishbone suspension, also known as double A-arm type independent suspension, double wishbone suspension fork has two upper and lower arms, the lateral force is absorbed by the two fork arms at the same time, carrying only the strut body weight, so a large lateral stiffness. Double-wishbone suspension wishbone upper and lower A-shaped front wheel can be accurately positioning the various parameters, when the nose wheel steering, two upper and lower wishbones can absorb suffered tire lateral force, combined with two fork arms the larger lateral stiffness, so that a smaller turning roll.
“Alpha middot; Romeo 159 front suspension uses a double-wishbone suspension.”
“the public double wishbone suspension structure of FIG turui “
double-wishbone suspension usually vertical unequal length wishbones (the short length), so that the wheels can automatically change the camber angle during vertical movement and Save small gauge changing reduced tire wear, and adaptively road, a large ground contact area of the tire, the good fit.
“double-wishbone suspension movement of good, Ferrari, Maserati and other super sports car use.”
compared to McPherson suspension double wishbone more than a rocker, not only take up more space, and it is difficult to determine positional parameters, so the front axle small car space and cost are generally not considered for the use of such suspension. However, it has a small roll, tunable, large ground contact area of the tire, grip performance, and therefore most of the front suspension of the car are made of pure blood double wishbone type suspension, it can be said double-wishbone suspension frame for movement born suspension, Ferrari, Maserati sports car and the like are used F1 – double-wishbone front suspension.
domestic double wishbone front suspension of the car mainly FAW Toyota Crown and FAW Toyota Reiz , as well as Audi’s luxury SUV.
Advantages: a transverse stiffness and excellent anti-roll performance, grip performance, road feel clear;
Disadvantages: the high manufacturing cost, complexity suspension positioning parameter setting.
Applicable models: before and after sports cars, sports cars and super premium SUV suspension.
