Description

Technical Field

[0001] This utility model relates to the field of automotive suspension shock absorber technology, specifically an automotive suspension shock absorber. Background Technology

[0002] Shock absorbers are an important component of a car's suspension system. Their main functions are to bear and transmit vertical loads, mitigate impacts from uneven road surfaces, emergency braking, acceleration, and cornering, and dampen vibrations caused by the elastic system. To reduce the car's cornering frequency and improve ride comfort, the vertical stiffness of the car's suspension is generally designed to be low. This results in lower roll stiffness, leading to greater lateral roll during cornering and affecting the car's stability.

[0003] As disclosed in the patent announcement number CN223447551U, an automotive suspension shock absorber includes a sleeve, the inner cavity of which is provided with a movable block, the inner wall of which is provided with a spiral hole, the top of which is fixedly connected to a vertical tube, the bottom of which is connected to a short tube, the bottom of which communicates with the top of the spiral hole, and a first circular plate is fixedly sleeved on the surface of the sleeve.

[0004] Although it achieves the injection of damping fluid into the inner cavity of the sleeve, during the damping process, when the moving block moves downward, the damping fluid at the bottom of the moving block is squeezed and slowly enters the inner cavity of the riser through the spiral hole and short pipe. The damping fluid provides damping support for the moving block, and then provides damping support for the car. By setting the first circular plate, the second circular plate and the first spring, the riser and sleeve are damped and supported again. By using a combination of multiple damping methods, the damping effect of the shock absorber is greatly improved, and the car is protected.

[0005] However, this does not solve the problem that existing car suspension shock absorbers are generally not conducive to convenient cushioning and damping of the car suspension during use. When the car is driving on bumpy roads, it is easy for the suspension shock absorber to perform convenient multi-stage damping, which affects the effect of the car suspension damping and affects the comfort of the ride.
