Independent suspension has a variety of structural forms, the key is divided into double wishbone, single wishbone, double longitudinal arm, single longitudinal arm, McPherson twisted beam steering lamp arm. For the independent suspension with different structural forms, only the structural characteristics are different, but also many basic characteristics are also very different. Comments are often carried out the following aspects:

(1) The ratio of height to width of the roll management center of a car is called the aspect ratio of the roll management center when the car body causes a roll according to the horizontal vertical plane diagram of the left right wheel Management Center under the effect of side force. The center of roll management is high, the distance between the center of mass the center of mass of the car body is reduced, which can reduce the side arm roll torque, reduce the roll angle of the car body. However, if the management center of the plane bearing maintenance roll is too high, the lathe plane bearing will change the wheelbase greatly when the car body is tilted, accelerate the damage of the tire.

(2) The main parameters of precise positioning of wheels change when the wheels vibrate up down, such as kingpin inclination angle, kingpin caster angle, wheel camber angle wheel toe in. If the caster angle of kingpin changes greatly, it is very easy to cause shimmy of turning wheels; if the camber angle of wheels changes greatly, it will damage the reliability of straight driving of cars, also harm the change of wheelbase the damage rate of tires.

(3) When the car is driving on a constant circle, the car body rotates around the roll center line under the effect of side force, this rotation angle is called the body roll angle. The car body roll angle is related to the roll torque the total bending stiffness of the suspension system, which endangers the control reliability ride comfort of the car.

(4) The transverse bending stiffness of suspension system is harmful to control reliability. If the lateral bending stiffness of the suspension system on the steering shaft is small, it will easily lead to shimmy of the turning wheel.
