Embodiment Construction

[0036] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0037] figure 1 It is a structural schematic diagram of a rear wheel suspension device in the related art. Such as figure 1 As shown, the rear suspension includes a steering knuckle assembly 1, a shock absorber 2 whose lower end is connected to the inner side of the steering knuckle assembly 1, a transverse tie rod 3 whose one end is connected to the inner side of the steering knuckle assembly 1, and one end connected to the inner side of the steering knuckle assembly 1. A-shaped control arm 4 attached inboard. Wherein, the length of the transverse tie rod 3 is adjustable. The steering knuckle assembly 1 includes a steering knuckle and a brake, the brake bearing and the steering knuckle are fixed by interference fit, and the wheels ...

Abstract

The invention discloses a rear wheel suspension device and relates to the technical field of automobiles. A control arm comprises a first arm, a second arm and a connecting arm connecting the middle of the first arm and the middle of the second arm; the first arm and the second arm are mutually separated; one end of the first arm and one end of the second arm are hinged with a steering knuckle assembly; one end of the first arm and one end of the second arm are hinged to different positions of the steering knuckle assembly; one end of the first arm and one end of the second arm are hinged to different positions of the steering knuckle assembly, and the other end of the first arm is used for being selectively connected to one of multiple positions of the frame, so that the distance betweenthe frame and the steering knuckle assembly is adjustable, and the effect of adjusting the toe-in and the camber angle of the rear wheel is achieved. A transverse pull rod does not need to be arranged, the first arm and the second arm of the control arm are fixedly connected into a whole through the connecting arm, and due to the fact that the number of parts is reduced, the automobile rear spaceis saved, the automobile trunk space, the oil tank space and the speed reducer space are larger in arrangement space and more flexible in arrangement.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a rear wheel suspension device and an automobile. Background technique [0002] Suspension system is a general term for all force-transmitting connection devices between the frame of a car and the axle or wheels. impact force and attenuate the vibration caused by it, so as to ensure the smooth running of the car. [0003] McPherson suspension is a widely used suspension. MacPherson suspension includes A-shaped control arms, tie rods and shock absorbers. One end of the tie rod is connected to the steering knuckle assembly, and the other end of the tie rod is connected to the frame, so that by changing the length of the tie rod, the distance between the steering knuckle assembly and the frame can be changed, thereby adjusting the toe-in of the rear wheel (two The distance between the front ends of the rear wheels is smaller than the distance between the rear ends, and the di...
