Lower swinging arm

Abstract

The invention relates to a lower swinging arm. The lower swinging arm comprises a fork-arm lower swinging arm body, a ball pin is arranged on one side of the lower swinging arm body, a damper installing base is arranged on the lower swinging arm body, a first lining is arranged at the front end of the other side of the lower swinging arm body, and a second lining is arranged at the back end of the other side of the lower swinging arm body; the installing direction of the first lining and the installing direction of the second lining are different on the lower swinging arm body. According to the lower swinging arm, the installing position of the first lining and the installing position of the second lining on the lower swinging arm body are set; in other words, the positions of first discharging grooves in the first lining are same as the positions of second limiting blocks of the second lining, and the positions of first limiting blocks of the first lining are same as the positions of second discharging grooves of the second lining; according to the structure, the rigidity of the first lining is large in the left and right direction of a vehicle, and is small in the forward and backward direction and the torsion direction of the vehicle, and stable steering and comfortable driving can be achieved accordingly.

Description

technical field [0001] The invention belongs to the technical field of automobile suspension, in particular to a lower swing arm structure. Background technique [0002] The lower swing arm plays the role of bearing load in the suspension, guiding the wheel and absorbing vibrations, and can also provide mounting points for other suspension components such as shock absorbers. The bottom arm of modern automobiles is mostly made of sheet metal through stamping and welding processes. [0003] Such as figure 1 and figure 2 Shown is a schematic diagram of the structure of the lower swing arm in the prior art. The lower swing arm in the prior art is stamped and welded from multiple pieces of sheet metal, including a ball pin 01, a shock absorber mounting seat 02, a thrust rod bracket 03, and a hem Arm body 04 , bushing 05 , inner mounting plate 301 , inner reinforcing plate 401 and lower reinforcing plate 402 . The ball pin is connected to the steering knuckle on the wheel sid...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to provide a lower swing arm to solve the problems in the prior art that the connection between the lower swing arm and the sub-frame is complicated, the strength of the lower swing arm is low, and the stability and comfort of the bushing to the vehicle are poor.
