Problems solved by technology

However, the shock absorber with this structure, because its throttle holes are all circular through holes, when the oil flow is adjusted, there will be a phenomenon of sudden opening or sudden stop.
Applied in the suspension system of the car, it will make the ride comfort and handling stability of the car worse, and make the braking distance longer, and the ability to resist sideslip is poor

Abstract

The invention discloses a vibration-damper of adjustable damping force, which is characterized by the following: the piston rod (2) is hollow body within the adjustment bar (1); the spool (8) is set in the hollow body of piston rod in the valve body (10); the spool integrates with the adjustment bar; the orifices (14ú¼15) are opened on the spool radial corresponding to the oil-hole (5,6) on the piston rod; the elongated slots (14íõú¼15íõ) are set on the hole wall of orifice in connection with the orifices. The invention changes the position of oil-hole and orifice to adjust the damping force, which guarantees the fluid driving and stable operation.

Description

【Technical field】 [0001] The invention relates to a component of a suspension system in an automobile, in particular to a shock absorber with adjustable damping force in an active suspension system. 【Background technique】 [0002] In the suspension system of the car, the elastic element vibrates due to the impact. In order to improve the ride comfort of the car, a shock absorber is installed in parallel with the elastic element in the suspension. The working principle of the force shock absorber is that when the frame (or body) and the axle are vibrated relative to each other, the piston in the shock absorber moves up and down, and the oil in the shock absorber cavity repeatedly flows from one cavity to another. It flows into another cavity through a different pore. 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...
