Abstract
The utility model relates to a shock absorber with spiral centering springs. The shock absorber comprises an oil storage cylinder and a working cylinder, wherein the working cylinder is arranged inside the oil storage cylinder. A compression valve is arranged at the bottom of the working cylinder, a piston rod which axially moves is arranged inside the working cylinder, a piston valve is fixedly arranged at the bottom of the piston rod, a sealing assembly is arranged between the upper portion of the piston rod and the oil storage cylinder, and the spiral centering springs are arranged between the oil storage cylinder and the working cylinder. According to the shock absorber, assembling efficiency can be improved, and the piston rod, the working cylinder and the oil storage cylinder are always kept in good coaxility at the same time, therefore, friction force generated in the working process of the piston rod of the shock absorber can be reduced, the piston rod is beneficially protected from eccentric wear caused by disalignment of the shock absorber itself when the piston rod conducts linear reciprocating motion, noise and abnormal sound generated in the process of eccentric wear are eliminated, and the practical effect for prolonging the service life of the shock absorber is achieved.
Description
Technical field
The utility model belongs to the vehicle shock absorber technical field, relates in particular to a kind of vibration damper with the spiral centering spring.
Background technique
In the Vehicle Driving Cycle process, the piston rod of vibration damper moves up and down, and drives fluid and produces damping force by piston valve and compression valve, reaches the vibrational energy that absorbs vehicle, to guarantee to take advantage of the travelling comfort of driving.At present, existing vibration damper, its structure generally includes oil storage cylinder and is positioned at the clutch release slave cylinder of oil storage cylinder, in the clutch release slave cylinder bottom surface, compression valve has been housed, and the piston rod that can move up and down is housed in clutch release slave cylinder, and piston valve is housed on piston rod.Function due to vibration damper in vehicle makes piston rod do straight reciprocating motion with respect to clutch release slave cylinder always.Therefore, coaxality to clutch release slave cylinder and oil storage cylinder in processing requires high, be subject to the impact of assembly precision, in use, because gap between clutch release slave cylinder and oil storage cylinder is larger, the piston rod to-and-fro motion is frequent in addition, make vibration damper self disalignment and produce eccentric wear, and eccentric wear brings in the Vehicle Driving Cycle process and the noise abnormal sound occurs, reduced thus the working life of vibration damper, also increased and has taken advantage of the uncomfortable property of driving simultaneously.
The model utility content
The purpose of this utility model is to provide a kind of coaxality that can effectively guarantee shock absorber working cylinder and oil storage cylinder, avoids eccentric wear, thoroughly eliminates in using the noise abnormal sound occurred, and the vibration damper with the spiral centering spring that can increase the service life.
Realize that the technological scheme that the purpose of this utility model is taked is: this vibration damper comprises oil storage cylinder, is arranged on the clutch release slave cylinder in oil storage cylinder, the clutch release slave cylinder bottom is provided with compression valve, be provided with the piston rod of an axial motion in clutch release slave cylinder, bottom at piston rod is fixed with piston valve, be provided with black box between the top of piston rod and oil storage cylinder, it is characterized in that being provided with the spiral centering spring between oil storage cylinder and clutch release slave cylinder.
Described spiral centering spring is sleeved on the excircle of clutch release slave cylinder, and leaves between oil storage cylinder and be equipped with gap.
The vibration damper with the spiral centering spring of making according to such scheme; by the spiral centering spring is set; can when improving efficiency of assembling, guarantee piston rod; clutch release slave cylinder; oil storage cylinder is always in good coaxality; can reduce thus shock absorber piston rod frictional force in the course of the work; be conducive to protect piston rod to be unlikely the eccentric wear that is subject to vibration damper self disalignment and produces when doing straight reciprocating motion; thereby reach the noise abnormal sound produced while eliminating eccentric wear, improve the working life of vibration damper and take advantage of the practical effect of driving travelling comfort.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Referring to Fig. 1, the utility model is the vibration damper with the spiral centering spring, this vibration damper comprises oil storage cylinder 1, the piston rod 4 that oil storage cylinder 1 inside is set with successively clutch release slave cylinder 2 and moves reciprocatingly vertically, compression valve 3 is equipped with in clutch release slave cylinder 2 bottoms, be provided with sealing component 6 between the top of piston rod 4 and oil storage cylinder 1, piston valve 5 is equipped with in the bottom of piston rod 4, be provided with spiral centering spring 7 between described oil storage cylinder 1 and clutch release slave cylinder 2, this spiral centering spring 7 is sleeved on the excircle of clutch release slave cylinder 2, and leave and be equipped with gap between oil storage cylinder 1, be beneficial to clutch release slave cylinder 2 convenient when inserting oil storage cylinder 1, improve efficiency of assembling.This vibration damper is set with spiral centering spring 7 on the excircle of clutch release slave cylinder 2; can guarantee the coaxality of clutch release slave cylinder 2 and oil storage cylinder 1; make vibration damper after the sealing that presses; piston rod 4; clutch release slave cylinder 2, the coaxality of oil storage cylinder 1 these three parts is always in shape, is conducive to protect piston rod to be unlikely when doing straight reciprocating motion and is subject to vibration damper self disalignment and produces eccentric wear; reach the life-span of improving vibration damper, produce the practical effect of noise abnormal sound while eliminating eccentric wear.What further illustrate is, because the increase of spiral centering spring 7, the fluid of this vibration damper inside can flow along the helix of spiral centering spring 7 when vibration damper is worked, the stability that is conducive to fluid, reduce the foamed of fluid, by the sound of valve, also can greatly reduce thus the noise of vibration damper while reducing the work of vibration damper fluid.
