Embodiment Construction

[0042] The present invention will be described in detail below in conjunction with the drawings and embodiments.

[0043] Reference image 3 , The present invention is an independent suspension system with constant wheelbase and inclination angle parameters, including: shock absorber (501), U-shaped push-pull swing arm (201), A-shaped arm lever swing arm (101), guide rail (301) , 302), linear sliding guide sleeve (303, 304), rotating shaft mounting post (305, 306), fixed guide rail positioning seat (401, 402, 403, 404), wheel hub (601), tire (701), frame (801), the steering knuckle composition.

[0044] Reference image 3 with figure 2 , The present invention is an independent suspension system with constant wheelbase and inclination angle parameters. The axis A, B, and C of the A-shaped isometric lever swing arm (101) are on the same plane, and the axis lines are parallel to each other. Distance L2 = L3 = L1; The middle (103) (104) of the A-shaped equal-arm lever swing arm (101)...

Abstract

The invention relates to the field of automobile manufacturing and discloses an independent suspension system with invariable wheel tread and wheel base inclination parameters. When a connection hub at the top (102) of an A-shaped equal-arm lever swing arm (101) vertically swings along with ground up and down and under the counteraction force of a shock absorber (501), ends (204) and (205), in shaft connection with middle lever fulcrums (103) and (104) of the A-shaped equal-arm lever swing arm (101), of a U-shaped push-pull swing arm (201) are driven to swing around E. Bottoms (105) and (106)slide linearly when the A-shaped equal-arm lever swing arm (101) swings, and since an axis distance L2 is equal to L3 and L1, a vertical bounce trail of the top (102) of the A-shaped equal-arm lever swing arm (101) is always perpendicular to rotating axis E of (202) and (203) of the U-shaped push-pull swing arm (201). Wheels are kept in linear bounce along a perpendicular direction of an automobile body, a maximum contact area of tires and the ground is realized, and parameters including king pin inclination, wheel toe-in, outward inclination, wheel tread, wheel base and the like are kept unchanged. Therefore, controllability, safety, stability and comfort of automobiles are idealized.

Description

Technical field [0001] The invention relates to the field of automobile manufacturing, in particular to an automobile independent suspension system. Background technique [0002] For a long time, the driving stability and comfort of a car are closely related to the suspension system in the chassis structure. Nowadays, most cars use independent suspension systems. According to their different structural forms, independent suspension systems are mainly divided into: Macpherson suspension, double Wishbone suspension and multi-link suspension. But all current independent suspension systems have a common problem, that is, the wheelbase, wheelbase and inclination angle of the wheels will constantly change with the wheel beating. In addition, the change of wheel inclination reduces the tire contact area, increases tire wear, and reduces tire adhesion to the ground. Limited by the structural characteristics of the existing suspension, it is impossible to keep the wheels perpendicular t...
