Abstract

The invention discloses a front suspension system and a vehicle, and belongs to the technical field of automobile suspensions. The front suspension system includes: a knuckle; an upper control arm; and an auxiliary frame assembly which comprises a left longitudinal beam, a right longitudinal beam, a front cross beam and a rear cross beam, wherein the front cross beam and the rear cross beam are connected with the left longitudinal beam and the right longitudinal beam in a welded mode, wherein first welding seams are formed between the front cross beam and the left longitudinal beam and between the front cross beam and the right longitudinal beam, and included angles are formed between the first welding seams and the vertical plane; a first lower control arm and a secondlower control arm, wherein one end of the first lower control arm is connected with the auxiliary frame assembly, the other end of the first lower control arm is connected with the steering knuckle through a ball pin, one end of the second lower control arm is connected with the auxiliary frame assembly, and the other end of the second lower control arm is also connected with the steering knuckle through a ball pin, the intersection point of the axes of the first lower control arm and the second lower control arm is a virtual main pin lower point, and the virtual main pin lower point is lower than the auxiliary frame assembly; and a front sliding column assembly. The front suspension system and the vehicle are high in applicability, easy to form and high in deformation resistance.

Description

technical field

[0001] The invention relates to the technical field of automobile suspension, in particular to a front suspension system and a vehicle. Background technique

[0002] Suspension is a general term for devices that ensure the elastic connection between the wheel or axle and the vehicle's load-carrying system (frame or load-bearing body) and can transmit loads, ease shocks, attenuate vibrations, and adjust the position of the vehicle body during driving. Car suspension can be mainly divided into two categories: non-independent suspension and independent suspension.

[0003] Although the current conventional independent suspension can meet the suspension design requirements in terms of function, when the wheel jumps, the wheel alignment parameters will change, and any change in the wheel alignment parameters will have an adverse effect on the car's handling stability or other aspects of performance. . In addition, the sub-frame of the existing suspension system ...
