Four-bar-linkage independent rear suspension of automobile and automobile

Abstract

The invention relates to a four-bar-linkage independent rear suspension of an automobile and an automobile. The suspension comprises a wheel bracket, a sub automobile frame, a first lateral arm, a second lateral arm, a vertical arm, and a toe-in rod, wherein the first lateral arm is located on a wheel center of the wheel bracket, and is provided with two connecting ends; one of the connecting ends of the first lateral arm is connected with the wheel bracket, and the other connecting end of the first lateral arm is connected with the sub automobile frame; the second lateral arm is located under the wheel center of the wheel bracket, and is connected with the wheel bracket on one side close to the wheel bracket in the lateral direction of the automobile; on one side close to the sub automobile frame, the second lateral arm is connected with the sub automobile frame; the vertical arm is provided with two connecting ends, wherein the upper connecting end of the vertical arm is connected with the wheel bracket, and the lower connecting end of the vertical arm is connected with the second lateral arm; and the toe-in rod is used for adjusting the toe-in angle of a wheel, and is provided with two connecting ends, wherein one of the connecting ends of the toe-in rod is connected with the wheel bracket, and the other connecting end of the toe-in rod is connected with the sub automobile frame. Through the adoption of the four-bar-linkage independent rear suspension disclosed by the invention, the torque formed by the longitudinal force can be effectively resisted by the vertical arm, and on a rough road, the NVH characteristic of the automobile is improved.

Description

technical field [0001] The invention relates to an automobile four-link independent rear suspension and an automobile. Background technique [0002] The rear suspension system in a car is an important system that transmits vertical, longitudinal and lateral forces to the car body. The suspension system controls the beating range of the wheels during the running of the car, controls the roll produced by the two vehicles when turning, and ensures that the car At the same time, the rear suspension system also needs to absorb the vibration from the ground, so as to meet the passengers' requirements for the ride comfort of the car, and the comfort requirements of the car when the number of passengers is different. [0003] The rear suspension system widely used in the market is a knife-edge four-link suspension. The rear suspension system mainly includes: three transverse arms connected between the sub-frame and the wheel bracket, one arranged along the running direction of the v...
