Problems solved by technology

The invention can automatically adjust the size of the damping to ensure the ride comfort and stability of the vehicle. However, the damping force of the invention can only be automatically changed within a certain range according to the specifications of the throttle groove. When the temperature changes cause the viscosity of the oil to change When the shock absorber damping cannot be adjusted further

Description

technical field [0001] The invention relates to a shock absorber, more specifically a shock absorber with a two-way pressure limiting piston. Background technique [0002] The shock absorber is a device used to suppress the shock when the spring rebounds after absorbing the shock and the impact from the road surface. It is widely used in the suspension of the car to accelerate the attenuation of the vibration of the frame and the body to improve the ride comfort of the car. The working principle of the shock absorber is that when the frame and the axle vibrate and there is relative movement, the piston in the shock absorber moves up and down, and the oil in the shock absorber cavity repeatedly flows from one cavity through different pores to another cavity Inside. At this time, the friction between the hole wall and the oil and the internal friction between the oil molecules form a damping force on the vibration, so that the vibration energy of the car is converted into hea...
