Abstract

The invention relates to an automobile suspension damper hydraulic position limit technology, in particular to a hydraulic position limit variable damper which can have the function of a normal damper and also can replace an elastic position limiter made of rubber in a normal suspension. The invention comprises a damper working cylinder, an oil storage cylinder sleeved at the external side of the damper working cylinder, a main piston matched with the damper working cylinder, and a compressed unloading valve and an oil inlet valve arranged on a bottom valve seat of the damper working cylinder. The invention is characterized in that a floating piston with an axial perforated oil liquid main passage at the middle part is arranged between the main piston and the bottom valve seat; the periphery of the floating piston oil liquid main passage is provided with a position limit damping hole; a position limit spring is arranged between the bottom valve seat and the floating piston. The invention can generate normal damping function, and can replace the elastic position limiter in the normal suspension made of rubber. The invention has better damping characteristic compared with the rubber position limiter.

Description

technical field [0001] The invention relates to the hydraulic limiter technology of the automobile suspension shock absorber, in particular to a hydraulic limiter that can not only function as a common shock absorber, but also replace the elastic limiter made of rubber in the common suspension. Damping shock absorbers. Background technique [0002] In general, there is an elastic limiter made of rubber in the car suspension to limit the excessive suspension travel, so as to avoid hard impact on the shock absorber and other components. However, almost all the energy generated by this elastic stopper is stored in the form of potential energy when it is compressed, and then it is released when it is extended, forming a large vibration. There is a hard impact when driving on a bad road, which seriously increases the dynamic load of the bearing system and greatly reduces the ride comfort of the car. Contents of the invention [0003] The purpose of the present invention is to...
