Abstract
The utility model relates to a compression hydraulic cushion system - valve is structure, including recoveing piston valve system, piston rod, working cylinder, compression valve system, compression valve system is located working cylinder top department, be equipped with in this working cylinder to recover piston valve system and piston rod, the piston rod with recover the piston valve and be connected, the working cylinder in still placed the throat working cylinder, this throat working cylinder is located and recovers between piston valve system with the compression valve is, the front end that recovers piston valve system is provided with the hydraulic cushion system - piston rod, is fixed with hydraulic cushion system - piston assembly on the body of rod of this hydraulic cushion system - piston rod, and this hydraulic cushion system - piston rod, hydraulic cushion system - piston assembly are located the throat working cylinder, the beneficial effects of the utility model are that: can effectually reduce vibrations and the impact that the vehicle produced, the travelling comfort and the security that have improved the vehicle when crossing the hole or acutely jolting.
Description
Technical field
The utility model belongs to damper valve system technical field, particularly relates to a kind of compression hydraulic trimmer valve architecture.
Background technique
Existing vibration damper produces damping force by compression valves system, the trend (as shown in Figure 1) stoping vibration damper to work downwards.The shortcoming of prior art is when vibration damper is subject to very large moment compressive force, and the damping force that compression valves system produces cannot offset external force completely, causes restoring piston valve system fast downwards, and may clash into compression valves system.
Summary of the invention
The purpose of this utility model is the deficiency overcoming the existence of prior art function, and provides a kind of compression hydraulic trimmer valve architecture that can improve vehicle body stability and travelling comfort.
The purpose of this utility model has been come by following technical solution, comprise and restore piston valve system, piston rod, clutch release slave cylinder, compression valves system, compression valves system is positioned at clutch release slave cylinder top end, be provided with in this clutch release slave cylinder and restore piston valve system and piston rod, piston rod is connected with recovery piston valve system, also be placed with reducing clutch release slave cylinder in described clutch release slave cylinder, this reducing clutch release slave cylinder is between recovery piston valve system and compression valves system; The front end of restoring piston valve system is provided with hydraulic cushion piston rod, and the body of rod of this hydraulic cushion piston rod is fixed with hydraulic cushion piston assembly, and this hydraulic cushion piston rod, hydraulic cushion piston assembly are positioned at reducing clutch release slave cylinder.
As preferably, described hydraulic cushion piston assembly is made up of damper piston, steel loop, hydraulic cushion ring, and this hydraulic cushion ring is fixed on damper piston, and steel loop is fixed on the outer wall of hydraulic cushion ring; In Spielpassung between this damper piston and reducing clutch release slave cylinder, and the external diameter of damper piston is less than the external diameter restoring piston valve system.
As preferably, described piston rod and hydraulic cushion piston rod are on same axis.
The beneficial effects of the utility model are: effectively can reducing the vehicle vibrations that produce and impact when crossing hole or severe jolt, improve travelling comfort and the Security of vehicle.
Accompanying drawing explanation
Fig. 1 is existing compression hydraulic trimmer valve architecture schematic diagram.
Fig. 2 is compression hydraulic trimmer 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, compression valves system; 5, reducing clutch release slave cylinder; 6, hydraulic cushion piston rod; 7, hydraulic cushion piston assembly; 51, necking end; 71, damper piston; 72, steel loop; 73, hydraulic cushion ring.
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, compression valves system 4, compression valves system 4 is positioned at clutch release slave cylinder 3 top end, be provided with in this clutch release slave cylinder 3 and restore piston valve system 1 and piston rod 2, piston rod 2 is connected with recovery piston valve system 1, also be placed with reducing clutch release slave cylinder 5 in described clutch release slave cylinder 3, this reducing clutch release slave cylinder 5 is between recovery piston valve system 1 and compression valves system 4; The front end of restoring piston valve system 1 is provided with hydraulic cushion piston rod 6, and the body of rod of this hydraulic cushion piston rod 6 is fixed with hydraulic cushion piston assembly 7, and this hydraulic cushion piston rod 6, hydraulic cushion piston assembly 7 are positioned at reducing clutch release slave cylinder 5.
Described hydraulic cushion piston assembly 7 is made up of damper piston 71, steel loop 72, hydraulic cushion ring 73, and this hydraulic cushion ring 73 is fixed on damper piston 71, and steel loop 72 is fixed on the outer wall of hydraulic cushion ring 73; In Spielpassung between this damper piston 71 and reducing clutch release slave cylinder 5, and the external diameter of damper piston 71 is less than the external diameter restoring piston valve system 1; Do not work in most reducing clutch release slave cylinder 5 region, only have and just start working to necking end 51, produce larger damping force.
Described piston rod 2 is on same axis with hydraulic cushion piston rod 6.
Working principle of the present utility model is: when damper piston 71 works necking end 51 inside arriving reducing clutch release slave cylinder 5, because the gap between damper piston 71 and reducing clutch release slave cylinder 5 is very little, fluid produces very large pressure, stops vibration damper to compress, play buffer function with this.Its objective is and be that vibration damper can not be compressed to the end when being subject to accidental shock quickly, prevent piston rod 2 and compression valves system 4 from producing and clash into.
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.
