Problems solved by technology

When the road conditions on which the vehicle is driving exceed the adaptable range, the excessive shock and vibration cannot be suppressed, and the damping performance of the shock absorber cannot be adjusted during the driving process of the vehicle, let alone automatically adjusted randomly
Moreover, the structure of the used valve parts is complex, the oil cannot fully circulate inside and outside the working cylinder, the heat dissipation effect is poor, and the sealing elements often fail prematurely due to the influence of excessive temperature

Embodiment approach

[0020] Referring to Fig. 4, it is embodiment 1 of the present invention, shows in the figure that upper limiter 8 and lower limiter 10 can be configured simultaneously, and are placed on the upper and lower positions of piston 9 respectively.

[0021] Referring to Fig. 5, it is embodiment 2 of the present invention, shows in the figure that upper limiter 8 can be separately configured on the top of piston 9.

[0022] Referring to FIG. 6 , it is Embodiment 3 of the present invention, which shows that the lower limiter 10 can be separately configured at the lower part of the piston 9 near the bottom valve seat.

[0023] The upper limiter 8 in the present invention comprises corresponding spring seats up and down, and a pressure spring is housed between the two spring seats for buffering when the piston moves upwards quickly. The lower limiter 10 includes an upper spring seat and a lower spring seat, and a pressure spring is installed between the two spring seats for buffering wh...

Abstract

This invention relates to a pump offset relative damping-variable vibration damper including an outer cylinder with sealed top and bottom, a hydraulic working cylinder is set in it and contains a piston with a circulation hole, a piston rod connected with it and a retainer, the lower part of the working cylinder is connected with a bottom valve base, the upper part is connected with a relief valve base and an oil seal base, an oil bossing is set between the working cylinder and the outer tube wall and an oil circulation channel is formed between the outside wall of the working cylinder and the inside wall of an outer cylinder, an inlet single-way valve, a circulation single-way valve and a damped single-way valve are set at the port of the circulation channels.

Description

technical field [0001] The invention belongs to the technical field of configuration of vehicle suspension devices, and relates to a pump-type displacement-related variable damping shock absorber suitable for various vehicle suspension systems. Background technique [0002] In the known technology, the shock absorber for vehicle suspension is usually provided with a recovery unloading valve, a recovery throttle valve and a flow valve, and a compensating valve, a compression throttle valve and a compression unloading valve are arranged on the bottom valve seat. During the running of the vehicle, the piston is mainly prevented from moving up and down by the reaction force generated by the damping effect of the above-mentioned valve, thereby absorbing the vibration energy of the vehicle and converting it into heat energy. And the size of its damping force depends on the size of the elasticity of each valve piece valve plate group. That is to say, once the valve plate groups ar...
