Description
Technical Field
The present utility model relates to a cap member for an automobile shock absorber and an automobile shock absorber.
Background
Currently, conventional vehicles use various suspensions to improve the operability or riding comfort. In particular, a suspension (shock absorber) incorporating a spring is used between the wheel and the vehicle body in order to absorb vibration or impact force.
In general, a shock absorber includes a cylinder filled with a working fluid, a cap member covering one end of the cylinder, a piston fitted into the cylinder via the cap member, a piston rod fitted over the piston, a dust cover fitted over the outside of the cap member, and the like. The interior of the cylinder of the shock absorber is divided into an upper chamber and a lower chamber by a piston having a flow valve and a extension valve. A reserve tube is formed at the lower end of the cylinder body, and is connected with the lower chamber via a partition plate having a compression valve and a compensation valve.
The shock absorber achieves a shock absorbing effect in the following manner.
When the piston rod of the shock absorber is compressed, the piston descends, the volume of the upper cavity is increased, the volume of the lower cavity is reduced, the circulation valve is opened, and oil in the lower cavity enters the upper cavity through the circulation valve; and simultaneously, a part of oil liquid of the compression valve is opened to enter the oil storage cylinder. The throttling action of the two valves on the oil liquid causes the shock absorber to generate damping action when in compression motion.
In addition, when the piston rod of the shock absorber is stretched, the piston moves upwards, the volume of the upper cavity is reduced, the volume of the lower cavity is increased, the stretching valve is opened, and oil in the upper cavity enters the lower cavity through the stretching valve; and simultaneously, the compensation valve is opened, and a part of oil enters the lower cavity from the oil storage cylinder. The throttling action of the two valves on the oil liquid causes the shock absorber to generate damping action during the stretching movement.
As for the shock absorber, the shock absorber of different strokes (piston rod strokes are different, i.e., the pressing height) is required because the hard spot and the weight of the whole vehicle are different from one vehicle to another. One of the stroke determining factors of the piston rod is the length of the dust cap covering the piston rod and the height of the cap member. Accordingly, there is a need in the art to manufacture cap members of different heights to meet the requirements of different vehicles. The current cap member is formed as a unitary structure by mold manufacturing, so that it is necessary to manufacture a new mold without breaking in order to manufacture cap members of different heights, and thus the production cost of the shock absorber becomes high.
