Problems solved by technology

[0003] Most of the rear suspension trailing arms in the prior art are arranged separately for the left trailing arm and the right trailing arm, and the two trailing arms are connected by a rigid bridge. The structure is simple, but the unsprung weight is heavy and the comfort is insufficient.

Embodiment Construction

[0022] to combine Figure 1-Figure 6 , the present invention provides an integral trailing arm semi-independent suspension structure, including a left rear brake 1, an integral trailing arm 2, a left constant velocity transmission shaft 3, a reducer and a differential assembly 4, a driving motor 5, a right Constant velocity transmission shaft 6, right rear brake 7, spring seat 8, rear spring 9, rear shock absorber 10.

[0023] The integral trailing arm is a circular tube U-shaped beam structure, which is connected to the frame or the vehicle body through two symmetrical rubber sleeve structures. Preferably, in order to further reduce weight, the integral trailing arm can be made of die-casting aluminum alloys arranged symmetrically. The trailing arm is formed by connecting the round tubes in the middle, and the structure integrates the installation points of the rear brake, rear shock absorber and spring seat. When the beating range of the left and right rear wheels is incons...

Abstract

The invention discloses a semi-independentsuspension structure with integrateddragging arms. The semi-independentsuspension structure comprises an integrated dragging arm assembly, a spring seat, a rear spring, a rear vibration damper, a left rear brake, a right rear brake, a left constant-speed transmission shaft, a right constant-speed transmission shaft, a speed reducer and differential mechanism assembly and a driving motor. The semi-independentsuspension structure is simple and is easy to maintain; the unsprung weight is reduced; the problem of safety is solved; the production cost is low; meanwhile, the riding comfortableness is also considered; compared with the conventional dragging arm scheme, a left dragging arm and a right dragging arm are integrated; a middle cross beam can effectively bear torsion; a cross beam part is located in a reverse direction of driving of a vehicle, so that the space in the vehicle is correspondingly increased; the riding comfortableness is improved; the driving motor is fixedly connected to the speed reducer and differential mechanism assembly; the speed reducer and differential mechanism assembly is connected with a frame; the failure rate of electric components is greatly reduced; the semi-independentsuspension structure is applicable to small motor vehicles and small electric vehicles.

Description

technical field [0001] The invention relates to the technical field of automobile design and manufacture, in particular to an integral trailing arm semi-independent suspension structure. Background technique [0002] The rear suspension assembly mainly includes two structural forms: non-independent suspension and independent suspension. Among them, the structural characteristics of the non-independent suspension are: the wheels on both sides are connected by an integral axle, and the wheels and the axle are connected to the frame (or body) through elastic suspension. When one side of the wheel jumps due to uneven roads, it will inevitably cause the other side of the wheel to swing in the transverse plane of the car, which has the problem of poor driving comfort, especially when driving on uneven roads, the left and right wheels affect each other, and it is easy to Tilting the body directly affects ride comfort. The characteristics of independent suspension are: the axle is...
