Background
In the running process of the automobile, the shock absorber can alleviate the impact caused by the uneven road surface and inhibit the shock rebounded after the spring absorbs the shock, so that the vibration of the automobile body is attenuated at an accelerated speed, and the controllability and the comfort of the running of the automobile are ensured. These functions of the shock absorber are achieved by internal damping, which produces different damping at different vibration speeds. Different damping is taught through the chassis, subjective evaluation is carried out on the result, and finally the controllability and the comfort are met. However, the maneuverability and the comfort of the automobile are two opposite entities, and generally, the improvement of the maneuverability of the automobile brings about the reduction of the comfort, and usually a balance point is taken between the two.

Detailed Description
The invention is further described below with reference to the accompanying drawings and the detailed description.
Referring to fig. 1, the frequency self-induction damping adjusting shock absorber restoring valve assembly shown in the figure comprises a main piston 100, a flow-limiting valve plate 200, an additional piston 300, a gasket 400, a low-frequency restoring valve plate 500, a belleville spring 600 and a restoring nut 700, wherein the main piston 100, the flow-limiting valve plate 200, the additional piston 300, the gasket 400, the low-frequency restoring valve plate 500, the belleville spring 600 and the restoring nut 700 are sequentially installed in series through a connecting bolt 800, the connecting bolt 800 is in threaded connection with the restoring nut 700, and the main piston 100, the flow-limiting valve plate 200, the additional piston 300, the gasket 400, the low-frequency restoring valve plate 500 and the belleville spring 600 are locked together through the restoring nut.
The main piston 100 and the additional piston 300 are made of powder metallurgy.
The shim 400 is located in the bore of the additional piston 300 and in combination with the shim 400 creates the through-hole 310. The disc spring 600 presses the additional piston 300 against the restrictor plate 200 via the disc spring washer 610, and the restrictor plate 200 also abuts against the convex ring 110 of the main piston 100, and the restrictor plate 200 is provided with an axially through flow hole 210.
In addition, a recovery and compression oil flow hole 120 is provided in the master piston 100.
The reset nut 700 presses the low frequency reset valve plate 500 against the male ring 320 of the additional piston 300 by a series of reset valve plate spacers 710, 720, 730, 740, 750, 760, and the gap 770 between the low frequency reset valve plate 500 and the male ring 320 is adjusted by these reset valve plate spacers 710, 720, 730, 740, 750, 760.
Referring to fig. 2, during a rebound motion of the shock absorber, during a low-frequency motion, oil of the shock absorber passes through the rebound and compression oil flow hole 120 of the main piston 100 and then passes through the flow hole 210 of the restrictor plate 200, and during the low-frequency motion, a damping force value is low, the accessory piston 300 does not move downward (i.e., in the direction of the rebound nut 700), and finally passes through the normal flow hole 310 formed by the combination of the additional piston 300 and the shim 400 and then flows out through a gap 770 between the low-frequency reset plate 500 and the convex ring 320, wherein damping is generated by the low-frequency rebound plate 500 at the lower part of the additional piston 300 (see ② in fig. 2).
As the frequency of motion gradually increases to a mid-frequency, the damping is determined by the area of the constant-bore 310 created by the additional piston 300 in combination with the shim 400.
When the piston moves at a high frequency, the additional piston 300 moves downward against the resistance of the disc spring 600, so that the gap 160 between the restrictor 200 and the convex ring 110 of the main piston 100 is kept open, and another part of the oil of the shock absorber flows out through the gap 160 between the restrictor 200 and the convex ring 110 of the main piston 100, and the damping is mainly generated by the disc spring 600. The elastic force of the belleville spring 600 inhibits the downward movement of the additional piston 300. Thus, the present invention provides for damping to be generated by different units at different frequencies of return motion.
