Independent suspension has a variety of structural forms, which can be divided into double wishbone type, single wishbone type, double longitudinal arm type, single longitudinal arm type, McPherson type twisted beam steering lamp arm type. For independent suspension with different structure, self-made plane bearing has only different structural characteristics, but also many basic characteristics. Evaluation is often carried out in the following aspects:

(1) Roll management office height when the car body is tilted due to the side force in the vertical plane design drawing of the left right wheel management office, the plane bearing pulley rotates relative to the ground for a moment, which is called the roll management office height. The position of roll management office is high, the distance the center of mass to the center of mass of the car body is reduced, which can make the side force arm roll torque smaller, the body roll angle will also be reduced. However, if the roll management office is too high, the track width will change greatly when the vehicle body is tilted, the tire damage will be accelerated.

(2) With the change of the basic parameters of wheel positioning, the basic parameters of positioning such as kingpin inclination angle, kingpin caster angle, wheel camber angle wheel toe in will change when the wheel moves up down relative to the vehicle. If the caster angle of kingpin changes greatly, it is easy to change into a wheel cause shimmy; if the camber angle of the wheel changes greatly, it will damage the credibility of the car's straight-line driving, as well as the change of the track width the damage speed of the tire.

(3) When the car is driving on a stable circle, the car will rotate around the roll axis under the action of side force, which is called the car roll angle. The car roll angle is related to the roll torque the total roll angle bending strain specification of the suspension system, damages the handling reliability ride comfort of the car.

(4) The credibility of the lateral bending strain damage handling of the suspension system with transverse bending strain. If the lateral bending strain of the suspension system on the steering shaft is small, it is easy to change into wheels cause shimmy.
