Abstract
The utility model relates to an it is structure to recover hydraulic cushion system - valve, including recoveing piston valve system, piston rod, working cylinder, the piston rod the head end with recover piston valve system and link to each other, be fixed with hydraulic cushion system - piston assembly on the body of rod of piston rod, should restore the inner wall in close contact with of piston valve system and working cylinder, the intermural clearance fit that is in hydraulic cushion system - piston assembly and the working cylinder, hydraulic cushion system - piston assembly be located and recover between piston valve system holds with the throat of working cylinder, hydraulic cushion system - piston assembly by recover the buffer block and the hydraulic cushion system - piston valve is constituteed, it is fixed mutually with the hydraulic cushion system - piston valve to recover the buffer block, the external diameter of hydraulic cushion system - piston valve is less than the external diameter that recovers piston valve system, the beneficial effects of the utility model are that: can fall to the produced impact of automobile body the stability and the travelling comfort of improvement automobile body rapidly by effectual reduction vehicle wheel when jumping.
Description
Technical field
The utility model belongs to damper valve system technical field, particularly relates to a kind of recovery hydraulic buffering valve architecture.
Background technique
Existing damper valve system is the effect (as shown in Figure 1) being played buffering by the stiffness characteristics of return spring 5, the shortcoming of prior art is that the mechanically deformation of spring easily produces noise, spring need weld with stop collar, easy generation cleanliness issues, affect the quality of vibration damper, its buffer function is also more linear.
Summary of the invention
The purpose of this utility model is to overcome the deficiency that prior art function exists, and provides a kind of and can improve the stability of vehicle body and the recovery hydraulic buffering valve architecture of travelling comfort.
The purpose of this utility model has been come by following technical solution, comprises and restores piston valve system, piston rod, clutch release slave cylinder, and the head end of described piston rod is connected with recovery piston valve system, the body of rod of piston rod is fixed with hydraulic cushion piston assembly; The inwall close contact of this recovery piston valve system and clutch release slave cylinder, in Spielpassung between the inwall of hydraulic cushion piston assembly and clutch release slave cylinder; Described hydraulic cushion piston assembly is between recovery piston valve system and the necking end of clutch release slave cylinder.
As preferably, described hydraulic cushion piston assembly is by restoring buffer stopper and hydraulic cushion piston valve forms, and this recovery buffer stopper and hydraulic cushion piston valve fix, and the external diameter of hydraulic cushion piston valve is less than the external diameter restoring piston valve system.
The beneficial effects of the utility model for: effectively can reduce vehicle wheel when jumping and to fall rapidly the impact that vehicle body is produced, improve stability and the travelling comfort of vehicle body.
Accompanying drawing explanation
Fig. 1 is existing recovery hydraulic buffering valve architecture schematic diagram.
Fig. 2 is recovery hydraulic buffering valve architecture schematic diagram of the present utility model.
Label in accompanying drawing is respectively: 1, restore piston valve system; 2, piston rod; 3, clutch release slave cylinder; 4, hydraulic cushion piston assembly; 5, return spring; 31, necking end; 41, buffer stopper is restored; 42, hydraulic cushion piston valve.
Embodiment
Below in conjunction with accompanying drawing, detailed introduction is done to the utility model: as shown in Figure 2, the utility model comprises recovery piston valve system 1, piston rod 2, clutch release slave cylinder 3, the head end of described piston rod 2 is connected with recovery piston valve system 1, the body of rod of piston rod 2 is fixed with hydraulic cushion piston assembly 4; The inwall close contact of this recovery piston valve system 1 and clutch release slave cylinder 3, in Spielpassung between the inwall of hydraulic cushion piston assembly 4 and clutch release slave cylinder 3; Described hydraulic cushion piston assembly 4 is between recovery piston valve system 1 and the necking end 31 of clutch release slave cylinder 3.
Described hydraulic cushion piston assembly 4 is made up of recovery buffer stopper 41 and hydraulic cushion piston valve 42, and this recovery buffer stopper 41 fixes with hydraulic cushion piston valve 42, and the external diameter of hydraulic cushion piston valve 42 is less than the external diameter restoring piston valve system 1; And do not work in most of clutch release slave cylinder region, only have and just start working to necking end 31, produce very large recovery damping force, this design well utilizes hydraulic principle, adopts the design of clutch release slave cylinder reducing to realize cushioning effect.
Working principle of the present utility model is: when hydraulic cushion piston valve 42 works necking end 31 inside arriving clutch release slave cylinder 3, because the gap between hydraulic cushion piston valve 42 and clutch release slave cylinder 3 is very little, fluid produces very large pressure, stops vibration damper to move upward with this.Its objective is that hydraulic cushion piston valve 42 can produce very large recovery damping force before vibration damper Rapid stretching to maximum tension length, making vibration damper can not be stretched to maximum position immediately when stretching suddenly.
The utility model is not limited to above-mentioned mode of execution; no matter do any change on its shape or material are formed; every employing structural design provided by the utility model, is all one distortion of the present utility model, all should thinks within the utility model protection domain.
