Description

Valve seat for large lateral force shock absorber

Technical Field

The utility model relates to a vehicle shock absorber technical field, in particular to a disk seat for big lateral force bumper shock absorber.

Background

When the automobile passes through the uneven road surface, although the shock absorption spring in the shock absorption system can filter the shock of the road surface, the spring can still do reciprocating motion, and the shock absorber is used for inhibiting the spring from jumping back and forth. The structure of the shock absorber is that a piston rod with a piston is inserted into a cylinder, and the cylinder is filled with oil. The piston is provided with a throttling hole, so that the oil in the two parts of space separated by the piston can be supplemented with each other. The working principle of the shock absorber is that when the frame and the axle or the vehicle body and the axle are vibrated to move relatively, the piston in the shock absorber moves up and down, oil in the cavity of the shock absorber repeatedly flows into the other cavity from one cavity through different pores, and at the moment, the friction between the hole wall and the oil and the internal friction between oil molecules form damping force on the vibration, so that the vibration energy of the vehicle is converted into oil heat energy, and then the oil heat energy is absorbed by the shock absorber and dissipated into the atmosphere.

The disk seat and the piston rod cooperation of prior art's bumper shock absorber, the terminal surface department circumference of disk seat sets up a plurality of hydraulic fluid mouths, and fluid gets into in order to carry out the fuel feeding from the clearance between hydraulic fluid mouth and the piston rod, and when the bumper shock absorber bore great yawing force, the oil feed flow area of the hydraulic fluid mouth of the one side of piston rod slope can reduce to lead to the entering volume of fluid to diminish, the performance degradation of bumper shock absorber.
