Problems solved by technology

But when the upper and lower supports have enough elastic deformation, the axial pretightening force of the nut 6 will be greatly reduced, and the friction between the nut and the bolt is not enough to tighten the nut, and the nut and the bolt may occur Loose, resulting in failure of the connecting device, for this reason, the designer used double nuts to twist, but the space inside the car body is small, and the assembly is very inconvenient
More importantly, due to the elastic hysteresis of the upper and lower supports, the upper platen 10 and the nut 6 are sometimes separated and sometimes close together, constantly colliding and generating noise

Embodiment 1

[0020] like figure 1 As shown, the rear shock absorber 2 of the automobile includes a piston rod 11 and a casing 12, and is fixed on the body of the automobile through a connecting device, which includes a bolt 3, a nut 6, an upper support 4 and a lower support 5 and the like.

[0021] Specifically, the connecting device of the rear shock absorber of the automobile is arranged at the connection between the rear shock absorber 2 and the body, including one end being fixedly connected with the housing 12 of the rear shock absorber 2 and the other end passing through the body wall 1 and extending To the bolt 3 on the upper part of the body wall 1, the part of the bolt 3 located at the upper part of the body wall 1 is sleeved with an upper support 4, an upper pressure plate 10 and a nut 6 in sequence, and the upper pressure plate 10 increases the force-bearing area of ​​the reaction force of the nut 6. The large rear is transmitted to the upper support 4, and the upper support 4 ...

Embodiment 2

[0025] This embodiment is roughly the same as the first embodiment, the difference is that, as figure 2 As shown, the positioning structure may also include a boss 14 fixed between the side surface of the bolt 3 and the upper support 4 , and the boss 14 is buckled at the lower end of the upper pressing plate 10 . After the nut 6 fixes the upper pressing plate 10 and the boss 14, the upper pressing plate 10, the nut 6 and the boss 14 form a rigid whole. The positioning structure is simple in design, practical and reliable.

Abstract

The invention provides a connecting device for a rear shock absorber of an automobile, and belongs to the technical field of machinery. The connecting device solves the technical problems that the conventional connecting device for the rear shock absorber is easy to generate noise, the threaded connection is easy to cause loosening and falling off and the like. The connecting device for the rear shock absorber of the automobile is arranged on a connecting part of the rear shock absorber and a wall body of the automobile body, and comprises a bolt of which one end is fixedly connected with a shell of the rear shock absorber and the other end passes through the automobile body and extends to the upper part of the wall body of the automobile body; a part of the bolt positioned on the upper part of the wall body of the automobile body is orderly sleeved with an elastic upper support, an upper pressure plate and a nut; a part of the bolt positioned between the wall body of the automobile body and the shell of the rear shock absorber is sleeved with an elastic lower support; and a positioning structure ensuring rigid connection of the nut with the pressure plate is arranged between the bolt and the upper and lower supports. The device improves the connecting safety, and cannot generate noise when the automobile runs.

Description

technical field [0001] The invention belongs to the technical field of machinery, and relates to a connecting device for a rear shock absorber of an automobile. Background technique [0002] The rear suspension of an automobile is a general term for all force transmission devices between the body and the wheels, and generally includes three parts: elastic elements, shock absorbers, and guide mechanisms. When the car passes through the bumpy road, the wheel transmits the impact force to the elastic element. Generally, the spring element is a large spring. The large spring converts the one-time large-energy impact transmitted by the wheel into multiple small-energy impacts, and then passes the shock absorber. Multiple small energy shocks are eliminated, so that the body does not suffer too much vibration. The shock absorber is fixed on the vehicle body through a connecting device, and the general connecting device adopts a pin-type structure. [0003] like image 3 As shown ...
