Shock absorber and vehicle

Abstract

The invention belongs to the technical field of vehicles, and particularly relates to a shock absorber and a vehicle. The shock absorber comprises a connecting plate, a connecting bolt, a first shock-absorbing assembly and a second shock-absorbing assembly, wherein the first shock-absorbing assembly comprises a first sleeve and a first shock-absorbing part; the first shock-absorbing part covers afirst sleeve; the second shock-absorbing assembly comprises a second sleeve and a second shock-absorbing part; the second shock-absorbing part covers a second sleeve; and the connecting bolt sequentially passes through the first sleeve, the second sleeve and the connecting plate. According to the shock absorber of the embodiment, the first shock-absorbing part covers the first sleeve, and the second shock-absorbing part covers the second sleeve to avoid the problem that due effect is lost as a result of damages of the shocker absorber while a positioning metal sleeve is separated from a rubberring if tightening moment of force is relatively great.

Description

technical field [0001] The invention belongs to the technical field of vehicles, and in particular relates to a shock absorber and a vehicle. Background technique [0002] This section provides background information related to the present disclosure only and is not necessarily prior art. [0003] The shock absorbers used on vehicles in the prior art have the following two structures. The first type is that two shock absorbers are installed symmetrically in a complete set during installation, and the positioning metal sleeve is placed in the mounting hole of the passive end connection device, and the end faces are not Contact, during the bolt tightening process, when the connecting plate at the active end is compressed to the positioning metal sleeve, when the lower fixing plate contacts the positioning metal sleeve below, due to the large tightening torque, the positioning metal sleeve is separated from the rubber ring, causing The shock absorber is damaged and loses its d...

Problems solved by technology

[0003] The shock absorbers used on vehicles in the prior art have the following two structures. The first type is that two shock absorbers are installed symmetrically in a complete set during installation, and the positioning metal sleeve is placed in the mounting hole of the passive end connection device, and the end faces are not Contact, during the bolt tightening process, when the connecting plate at the active end is compressed to the positioning metal sleeve, when the lower fixing plate contacts the positioning metal sleeve below, due to the large tightening torque, the positioning metal sleeve is separated from the rubber ring, causing The shock absorber is damaged and loses its due effect, and the rubber metal plate is in direct metal contact with the passive end connection plate. When encountering an impact, the cushioning capacity is poor; the second type, the shock absorber is composed of a rubber main ring and a secondary ring. The center of the main ring has a mandrel sleeve vulcanized integrally with it. Except for the mandrel, the outer ring is made of rubber. When installing, the main ring and the auxiliary ring are used together. The edge of the mounting hole of the passive end connecting plate will continuously cut the rubber. Use leads to tearing of the rubber main ring, affecting the performance of the shock absorber and the attendance of the car
