Embodiment Construction
[0048] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0049] It should be noted that if there is a directional indication (such as up, down, left, right, front, back...) in the embodiment of the present invention, the directional indication is only used to explain the position in a certain posture (as shown in the accompanying drawing). If the specific posture changes, the directional indication will also change accordingly.
[0050] In addition, if there are descriptions involving "first", "second" and ...

The invention discloses a caster angle adjustment structure, a suspension and a vehicle, wherein the caster angle adjustment structure includes a lower swing arm assembly, a sub-frame assembly and an eccentric bush adjustment structure, and the sub-frame assembly includes The first mounting part and the second mounting part are provided, the lower swing arm assembly has two ends distributed along the left and right directions, and one end of the lower swing arm assembly is formed with a first mounting arm extending forward and backward and a second mounting arm extending left and right. The end of the first mounting arm is hingedly mounted on the first mounting part, the end of the second mounting arm is hingedly mounted on the second mounting part, the other end of the lower swing arm assembly is used to connect with the suspension transmission structure, and the eccentric bushing The sleeve adjustment structure is arranged between the end of the first installation arm and the first installation part. In the technical solution provided by the present invention, the adjusting structure of the eccentric bush drives the first mounting part to shift left and right along the vehicle body, thereby driving the connecting end of the lower swing arm assembly and the suspension transmission structure to shift to adjust the wheel caster angle.
Description
technical field [0001] The invention relates to the field of automobiles, in particular to a wheel caster adjustment structure, a suspension and a vehicle. Background technique [0002] Existing light passenger cars adopt McPherson front independent suspension. Due to the manufacturing error of the body and sub-frame and the plastic deformation of the installation point during use, the position of the ball pin changes, and the caster angle of the kingpin is out of tolerance, resulting in Poor driving stability and other issues. [0003] At present, the McPherson front independent suspension structure generally adopts: the upper end of the shock absorber is fixed on the vehicle body, the lower swing arm is fixed on the sub-frame, and the lower end of the shock absorber and the steering knuckle are fixed to the outer end of the lower swing arm through ball pins. Due to the limitation of the connecting structure between the gear and the vehicle body, the connecting structure b...
