Abstract
The utility model relates to a hydraulic cushion system - bumper shock absorber, including a store oil section of thick bamboo, working cylinder, piston rod, piston, the working cylinder be located a store oil section of thick bamboo, the piston is fixed in on the piston rod, this piston, piston rod are located the working cylinder, the one end of working cylinder be the throat jar, for throat department between this throat jar and the working cylinder, the piston activity is taken things in working cylinder and throat, is fixed with the sealing ring on the outer wall of this piston, the diameter of piston be greater than throat jar inner wall diameter and be less than working cylinder inner wall diameter, the beneficial effects of the utility model are that: through this hydraulic cushion system - bumper shock absorber, can be so that the existing cushioning effect of bumper shock absorber, again can the noise reduction, promote the travelling comfort.
Description
Technical field
The utility model belongs to automobile absorber technical field, relates to a kind of hydraulic cushion vibration damper.
Background technique
Existing most vibration damper is by mechanical damping effect, as the vibration damper (as shown in Figure 1) by damping spring, offsets the strength that piston lever of reducer impacts, namely limited the upper jumping of vehicle body by this mode by the buffer function of damping spring; Because dependence mechanical damping, there is interaction in part own, be easy to produce noise, and the work of the fixed installation of part to vibration damper has a certain impact.
Summary of the invention
The purpose of this utility model is to overcome the deficiency that prior art exists, and provides a kind of and realize cushioning effect by hydraulic way, provides the prevention power of the upper jumping limit to vehicle, allows vehicle can the hydraulic cushion vibration damper of smooth-ride.
The purpose of this utility model has been come by following technical solution, comprises fuel tank, clutch release slave cylinder, piston rod, piston, and described clutch release slave cylinder is positioned at fuel tank, and piston is fixed on piston rod; This piston, piston rod are positioned at clutch release slave cylinder; One end of described clutch release slave cylinder is mouth-pressing cylinder, and be reducing place between this mouth-pressing cylinder and clutch release slave cylinder, piston is active between clutch release slave cylinder and reducing place, and the outer wall of this piston is fixed with seal ring.
As preferably, the diameter of described piston is greater than mouth-pressing cylinder inner diameter and is less than clutch release slave cylinder inner diameter.
The beneficial effects of the utility model are: by this hydraulic cushion vibration damper, can make the existing buffer function of vibration damper, can reduce noise again, promote travelling comfort.
Accompanying drawing explanation
Fig. 1 is existing buffer structural representation.
Fig. 2 is hydraulic cushion shock absorber structure schematic diagram of the present utility model.
Fig. 3 is hydraulic cushion vibration damper of the present utility model upwards working procedure structural representation.
Fig. 4 is hydraulic cushion damping curve schematic diagram of the present utility model.
Label in accompanying drawing is respectively: 1, fuel tank; 2, clutch release slave cylinder; 3, piston rod; 4, piston; 5, seal ring; 21, mouth-pressing cylinder; 22, reducing place.
Embodiment
Do detailed introduction below in conjunction with accompanying drawing to the utility model: as shown in Figure 2, the utility model comprises fuel tank 1, clutch release slave cylinder 2, piston rod 3, piston 4, and described clutch release slave cylinder 2 is positioned at fuel tank 1, and piston 4 is fixed on piston rod 3; This piston 4, piston rod 3 are positioned at clutch release slave cylinder 2; One end of described clutch release slave cylinder 2 is mouth-pressing cylinder 21, and be reducing place 22 between this mouth-pressing cylinder 21 and clutch release slave cylinder 2, piston 4 is active between clutch release slave cylinder 2 and reducing place 22, the outer wall of this piston 4 is fixed with seal ring 5; The diameter of described piston 4 is greater than mouth-pressing cylinder 21 inner diameter and is less than clutch release slave cylinder 2 inner diameter.
Working principle of the present utility model is: as shown in Figure 3, when vibration damper because vehicle body is jumped, when piston rod 3 moves upward and reaches Near The Upper Limit, because fluid flows through the specific channel of reducing place 22 of clutch release slave cylinder 2, hydraulic damping can be produced, buffer function is played in this damping, and namely stop moving upward of piston rod 3, piston is now positioned at reducing place 22 of clutch release slave cylinder 2.Curve as accompanying drawing 4 is typical hydraulic cushion damping curve.
In addition, recovery, the compression valves system of vibration damper itself need mate according to normal design, can bear the effect of vibration damper damping.
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.
