Abstract

In order to solve the problems of failure and abnormal sound caused by too low temperature of a shock absorber, a temperature self-adaptive automobile shock absorber is provided. The shock absorber comprises a shock absorption cylinder body, the shock absorption cylinder body comprises a working cavity and a liquid storage cavity which are separated by a working cylinder, and the working cavity and the liquid storage cavity are communicated through a valve. The working cavity and the liquid storage cavity are filled with oil, a piston is arranged in the working cavity, and a temperature control device is arranged in the liquid storage cavity. A temperature control device is additionally arranged in the liquid storage cavity, when the temperature of oil liquid is too low, the oil liquid in the liquid storage cavity is heated, the viscosity of the oil liquid is guaranteed, embrittlement of a sealing piece is reduced, and therefore a series of failure and noise problems caused by the too low temperature of the shock absorber can be avoided.

Description

technical field [0001] The invention relates to the field of shock absorbers, in particular to a temperature adaptive automobile shock absorber. Background technique [0002] The shock absorber is an important part of the car. The car cylinder hydraulic shock absorber is an important part of the car. It is widely used in the suspension system of the car. This kind of shock absorber can attenuate the vibration between the frame and the body. Improve the ride comfort of the car. The working principle of the cylinder hydraulic shock absorber is that the oil in the working cylinder repeatedly passes through the narrow valve to generate a continuous nonlinear damping force, so that the vibration energy of the body and frame is converted into heat energy, so as to achieve the purpose of damping vibration. [0003] However, when the temperature of the cylinder type hydraulic shock absorber is low (that is, in severe cold weather), the oil seal rubber on the shock absorber will bec...
