Embodiment Construction
[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0021] The purpose of the present invention is to provide a new type of shock absorber valve system that can still adjust the damping force after the shock absorber is sealed. An adjustment block is arranged under the connecting rod. The adjustment block includes an adjustment nut and an adjustment bracket. The adjustment nut is threaded on the At the lower part of the connecting rod, the adjusting bracket is inserted into the adjusting hole of the bottom valve...

The invention provides a novel shock absorber valve system capable of adjusting the damping force after sealing of a shock absorber. The novel shock absorber valve system comprises supporting sheets,circulation valve sheets, pistons, reset valve sheets, springs and bottom valves, wherein the supporting sheets, the circulation valve sheets, the pistons, the reset valve sheets and the springs are sequentially assembled on a connection rod, the connection rod is further equipped with an adjusting block, the adjusting block comprises an adjusting nut and adjusting stands, the adjusting nut is connected to the lower part of the connection rod through a thread, the adjusting stands are inserted into adjusting holes of the bottom valves, accurate and stable limiting of the adjusting block is ensured, thus the adjusting stands can only move in the vertical direction, and the structure is very simple; after the shock absorber is sealed, by rotating the connection rod, the adjusting block movesup and down along the thread of the connection rod under the limiting effect of the bottom valves, the pre-tightening force of the springs between the adjusting block and the reset valve sheets changes accordingly, the damping force of the oil liquid flowing by the reset valve sheets changes accordingly, the purpose that the damping force can be still adjusted after the shock absorber is sealed is realized, the adjusting process is convenient to operate, and the novel shock absorber valve system is applicable to various kinds of existing binocular shock absorbers, and has the extremely high practicality.
Description
technical field [0001] The invention relates to the field of automobile shock absorber manufacturing, in particular to a novel shock absorber valve system capable of adjusting the damping force of the shock absorber after it is sealed. Background technique [0002] In today's automobile design and manufacture, the suspension system of the automobile is an important part of the automobile. The vibrator is an important part of the car suspension system. [0003] The traditional twin-tube hydraulic shock absorber has the advantages of mature technology, simple structure, and low cost. By throttling and reducing the pressure of the oil inside the shock absorber, it forms a damping force opposite to the relative movement speed of the vehicle body to achieve vibration reduction. The effect is to improve the smoothness and comfort of the vehicle. However, the traditional shock absorber valve system is connected by threads or rivets. After the shock absorber is installed and seale...
