Abstract

The utility model provides a grade regulating mode hydraulic shock absorber with simple structure and low production cost, which comprises a working cylinder, an oil storage cylinder, a piston rod component and a compression valve, wherein the compression valve is mounted on the lower end of the working cylinder, the upper end of the working cylinder adopts a guide bushing and an oil seal, and the piston rod component comprises a restoring valve and a piston rod, wherein the restoring valve is mounted on the piston rod and is arranged in the working cylinder, the working cylinder is arranged in the oil storage cylinder, and a longitudinal flow discharge groove is arranged on the working cylinder. The grade regulating mode hydraulic shock absorber utilizes the flow discharge groove on the working cylinder to change thruflow area when vibration-damping liquid passes through the compression valve, thereby reaching the purpose of changing damping torque of the shock absorber, and leading a vehicle to have excellent comfort feeling when the vehicle is running under different loading conditions. The grade regulating mode hydraulic shock absorber has simple structure, and simultaneously has stronger vibration-proof function and wider application scope.

Description

Level mode dydraulic shock absorber
Technical field
The utility model relates to a kind of dydraulic shock absorber, particularly relates to a kind of grade of mode dydraulic shock absorber.
Background technique
For adapting to vehicle reaches more and more higher travelling comfort at different road travelings requirement, vehicle suspension system has developed into passive suspension, semi-active suspension and three kinds of suspension types of Active Suspension, the development of dydraulic shock absorber also never adjustable shock develop into the adjustable and automatic adjustable vibration damper of machinery, but at present the structure of the adjustable and automatic adjustable vibration damper of machinery comparatively complexity, cost are relative higher.
The model utility content
Technical problem to be solved in the utility model provides a kind of simple in structure, cost is low level mode dydraulic shock absorber.
The technological scheme that the utility model technical solution problem is adopted is: level mode dydraulic shock absorber, comprise clutch release slave cylinder, fuel tank, piston rod assembly and compression valve, described compression valve is installed in described clutch release slave cylinder lower end, guide sleeve and oil sealing sealing are adopted in described clutch release slave cylinder upper end, described piston rod assembly comprises resetting valve system and piston rod, described resetting valve system is installed on the described piston rod and is arranged in the clutch release slave cylinder, described clutch release slave cylinder is arranged in the described fuel tank, it is characterized in that: described clutch release slave cylinder is provided with dredging flow groove longitudinally.
The beneficial effects of the utility model are: utilize the dredging flow groove on the clutch release slave cylinder to change the flow area of damping fluid by compression valve, thereby reach the purpose that changes absorber damping force, make vehicle in the different good comfortable feels of Shi Douyou of travelling under the situation of carrying of taking advantage of.The utility model is simple in structure, and anti-vibration functions is stronger simultaneously, and accommodation is wider.
Description of drawings
Fig. 1 is a sectional view of the present utility model.
Embodiment
The basic structure of dydraulic shock absorber comprises clutch release slave cylinder, fuel tank, piston rod assembly and compression valve at present, and compression valve is installed in the clutch release slave cylinder lower end, and guide sleeve and oil sealing sealing are adopted in the clutch release slave cylinder upper end; Piston rod assembly comprises resetting valve system and piston rod, and resetting valve system is installed on the piston rod and is arranged in the clutch release slave cylinder; Clutch release slave cylinder is arranged in the fuel tank, thereby has formed epicoele, cavity of resorption and exocoel.When vehicle operating runs into projection, phugoid motion along with vehicle, when fuel tank moves up, piston rod moves down in clutch release slave cylinder relatively, at this moment, piston valve is washed open upwards, and the oil of cavity of resorption can not be subjected to the inflow epicoele of resistance, a part of damping fluid flows into exocoel by compression valve simultaneously, produces compression damping power; After wheel is crossed projection, wheel extends downwards, this moment, fuel tank moved downward, compression valve is opened, the damping oil of exocoel can not be subjected to the cavity of resorption that is back to of resistance, and the damping oil of epicoele flows into cavity of resorption by resetting valve system simultaneously, produces recovery damping force, thereby decay is satisfied the requirement of travelling comfort and Security by the caused Vehicular vibration of Uneven road.
As shown in Figure 1, on the clutch release slave cylinder 3 of the utility model with above-mentioned dydraulic shock absorber dredging flow groove 5 longitudinally is set, utilizes the dredging flow groove 5 on the clutch release slave cylinder 3 to change the flow area of damping fluid, thereby reach the purpose that changes absorber damping force by compression valve 4.Dredging flow groove 5 preferably is provided with many dredging flow grooves 5, and effect can be better like this.
The effect of each constituent element of the utility model is respectively: piston rod assembly 1 produces recovery damping force; Fuel tank 2 support air springs, store damping oil, and connect operator cabin and vehicle body or vehicle body and chassis with the upper and lower connecting head of piston rod; Clutch release slave cylinder 3 store oils, constitute the closed system that produces damping force with piston rod assembly 1; Compression valve 4 produces compression damping power; Dredging flow groove 5 produces different damping forces according to different operating modes.
Dredging flow groove 5 can adopt the horizontal hydraulic apparatus processing on the above-mentioned clutch release slave cylinder 3, and pultrusion of utilization pultrude process to guarantee the accuracy and the stability of size, guarantees that simultaneously the endoporus of clutch release slave cylinder 3 can not produce burr or other defects.During installation, piston rod assembly 1 and compression valve 4 that debugging is good are installed on the clutch release slave cylinder 3, in the fuel tank 2 of packing into, inject damping oil then, seal to get final product.
