Description

A new four-link independent suspension device for automobiles

technical field

The utility model relates to a suspension device for vehicles, in particular to a novel four-link independent suspension device for automobiles.

technical background

The rear suspension of current passenger cars, especially mid-to-high-end cars, mostly adopts a four-link independent suspension structure. The structure of this four-link suspension device is that the supporting member of the rear wheel of the car is connected to the car body through several connecting rods, and bushings are arranged on each connecting rod at least at the connection end with the car body, and the coil spring is used to The lower end of the buffer device formed with the shock absorber is supported on the rear wheel support member. The longitudinal arm and the wheel side shell of this structure are stamped and welded by steel plates. This device has a complicated structure and an unattractive appearance. higher cost.

Contents of the invention

In view of the above situation, the purpose of this utility model is to provide a new type of four-link independent suspension device for automobiles with simple and reasonable structure, beautiful appearance and relatively low cost.

The technical scheme of the utility model is: it comprises rear wheel supporting member (1), trailing arm (3), upper arm (6), lower arm (5), main swing arm (9), spring (7) and shock absorber (4), it is characterized in that: the upper arm (6) is arranged in the vertical direction to the whole vehicle, the upper arm (6) is connected with the rear wheel supporting member (1) and the bracket (8) through the bushing, and the trailing arm (3) passes through The bolt is connected with the rear wheel supporting member (1), one end of the main swing arm (9) is connected with the rear wheel supporting member (1) through a bush, and the other end is connected with the bracket (8) through a bush, and the adjusting device (10) It is fixed between the main swing arm (9) and the bracket (8), and the toe angle and camber angle of the wheel can be adjusted.

The bushing is fixedly embedded on each arm or the rear wheel supporting member; the lower end of the spring (7) is connected to the main swing arm (9), and the upper end is connected to the vehicle body; the lower end of the shock absorber (4) passes through The bushing is connected with the rear wheel supporting member, and the upper end is connected with the vehicle body.

The utility model can well make the lateral and longitudinal forces generated during braking and acceleration pass through the four arms in a straight line, thereby reducing the quality of the entire suspension system and simplifying the suspension system. The lateral force is borne by the upper arm, lower arm and main swing arm, the longitudinal force is borne by the trailing arm, lower arm and main swing arm, and the force generated by the up and down impact is borne by the spring and shock absorber, so the rigidity of the entire suspension system is very good , with good handling stability and ride comfort.
