X-type traction bar, rear suspension assembly and vehicle

Abstract

The invention discloses an X-type traction bar, a rear suspension assembly and a vehicle. The X-type traction bar comprises a first V-bar and a second V-bar; the first V-bar comprises a first bar and a second bar, and the first bar and the second bar are connected with each other at a first joint to form a V shape and are symmetrical relative to the symmetry axis; the second V-bar comprises a third bar and a fourth bar which are connected with each other at a second joint to form a V shape and symmetrical relative to the symmetry axis, and the first joint and the second joint are connected with each other. Therefore, compared with a V-type traction bar in the prior art, the X-type traction bar can be of smaller opening width in case of the same effective length and same opening angle. Thus, the X-type traction bar can adapt to smaller mounting space.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to an X-shaped thrust rod, a rear suspension assembly and a vehicle. Background technique [0002] The force between the axle and the vehicle is transmitted via thrust rods. In heavy-duty vehicles using leaf spring suspension, V-shaped thrust rods are usually used in order to transmit forces in the front-rear direction and left-right direction and prevent the rear axle from moving left and right relative to the vehicle or frame. [0003] figure 1 It is a schematic diagram of the vehicle frame and axle structure using the V-shaped thrust rod in the prior art. Such as figure 1 As shown, the V-shaped bar includes two bars connected to each other, and is connected to the axle 11 at the joint of the two bars, and connected to the cross beam of the vehicle frame 12 at the other end of the two bars. At the connection between the V-shaped rod and the axle 11, the mounting surface is...

Problems solved by technology

However, the deployment angle of this V-shaped thrust rod is fixed, so that the overall width of the V-shaped thrust rod is fixed, so that the width of the recess for installing the thrust rod in the box-shaped frame is insufficient, and it is difficult to install the V-shaped thrust rod, and assembly is difficult
