Problems solved by technology

However, with the increase of the damping force of the shock absorber, the maximum working temperature of the shock absorber will continue to increase, and the widest temperature range of the shock absorber is required to reach the requirement of -40°C-+180°C. At present, there is no one Polymer materials that can meet this working condition

Embodiment Construction

[0022] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0023] A shock absorber sealing system such as figure 1 As shown, a shock absorber sealing system includes an oil seal and a guide assembly, the oil seal assembly includes but not limited to rubber 1, a support frame 2 and a spring 3, and the guide assembly at least includes a guide 4, a stopper The oil ring 5, the inner bushing 6, and the oil deflecting ring 5 are installed above the inner bushing 6. The rubber body 1 of the oil seal body can be an elastic body such as nitrile rubber, hydrogenated nitrile rubber, fluororubber, etc., and the guide The oil deflector ring 5 of the device assembly is made of PTFE material.

[0024] Such as Figure 2-Figure 5 Shown is a schematic diagram of a part of the oil seal stru...

Abstract

The invention discloses a damper sealing system, comprising guider assemblies and an oil seal. The guider assemblies at least comprise a guider, a neck bush, and an oil retainer. The oil retainer is arranged on the neck bush. The invention provides design of a sealing system which can satisfy high-low temperature performance of a damper. Through developing sealing performance of each component in the system, on the premise of ensuring high-temperature use of the damper, low-temperature use requirements of the damper can be satisfied, so as to prolong service life of a sealing body and the damper.

Description

technical field [0001] The invention relates to a shock absorber sealing system, in particular to a shock absorber sealing system that needs to meet high and low temperature requirements. Background technique [0002] The shock absorber is one of the key components of the vehicle, which is crucial to the comfort and safety of the car. The working principle of the shock absorber is to transfer the kinetic energy generated by the bumps during the movement of the car to the shock absorber valve system through the shock absorber oil. The damping generated in motion is converted into heat energy, so the sealing of the shock absorber oil is very important to the life of the shock absorber. Generally, the main reason for the oil leakage of the shock absorber is the damage of the oil seal lip, the loss of sealing ability of the oil seal lip at low temperature and high temperature aging. Therefore, whether the sealing system of the shock absorber can function normally in high and lo...
