Abstract
The utility model discloses a shock absorber oil storage jar behind car has cylinder body (1), and the upper end of this cylinder body (1) is uncovered the upper end of cylinder body (1) is overlapped admittedly and is had steel bushing (2), is provided with the screw on the outer periphery of steel bushing (2). The utility model discloses a set up the threaded steel bushing on the cylinder body, the upper end that makes the oil storage jar is sealed and to be dismantled, and the chassis development phase of being convenient for is debugged with the compression damping the damping of restoring of shock absorber, has effectively shortened development period, has reduced the exemplar cost of manufacture, has design benefit, simple structure, implementation characteristics such as easy.
Description
Technical field
The utility model belongs to absorber technical field, specifically, and the oil storage cylinder particularly on car rear shock absorber.
Background technique
In the oil storage cylinder of car rear shock absorber, the parts such as guide holder, oil sealing, piston and bottom valve are generally installed, the upper end closure of oil storage cylinder.The connecting rod that lower end is connected with piston, the sealing of oil storage cylinder upper end is stretched out in its upper end.At present, the sealing of oil storage cylinder upper end adopts the mode of riveted joint, flanging or welding, such oil storage cylinder upper end-hole is shut completely, cannot take apart and regulate piston, bottom valve, can not debug thus in the chassis performance development stage to the recovery damping of vibration damper and compression damping.In order to improve the combination properties such as the precision of adjustment evaluation, higher chassis operational stability and smoothness, must be equipped with and overlap rear shock absorber more, not only the construction cycle is long, and exemplar fabricating cost is high.
Model utility content
Technical problem to be solved in the utility model is to provide a kind of car rear shock absorber oil storage cylinder can being convenient to damping debugging.
The technical solution of the utility model is as follows: a kind of car rear shock absorber oil storage cylinder, there is cylinder body (1), the upper end of this cylinder body (1) is uncovered, it is characterized in that: be installed with steel bushing (2) in the upper end of described cylinder body (1), the outer peripheral surface of steel bushing (2) is provided with screw thread.
Adopting above technological scheme, admittedly overlap steel bushing in cylinder body upper end, threading on steel bushing, can be socketed on steel bushing like this from tapped end cap by being screwed, end cap is by the upper end closure of cylinder body.Due to end cap and steel bushing screw-thread fit, unlimited dismounting can be carried out, can be convenient to regulate the piston in cylinder body and bottom valve in the chassis development stage, thus realization is debugged the recovery damping of vibration damper and compression damping, debugging operations is simple, convenient, fast on the one hand, on the other hand, effectively shorten the construction cycle, reduce exemplar fabricating cost.Steel bushing also plays reinforcing in cylinder body upper end, deforms to prevent cylinder body upper end or damages in the process of repeated disassembled and assembled.
To be connected firmly on cylinder body to make steel bushing, reliably, described steel bushing (2) and cylinder body (1) interference fit, and fixed by brazing between steel bushing (2) and cylinder body (1).
The end face of described steel bushing (2) and the either flush of cylinder body (1), pass through conical surface transition between the end face of steel bushing (2) and outer peripheral surface.Above structure has leading role, end cap is set with on steel bushing more convenient.
In order to ensure there being enough structural strengths, reduce cost of material as much as possible, the wall thickness of described cylinder body (1) is 1-1.5mm, and the wall thickness of steel bushing (2) is 2.5-3mm simultaneously.
Beneficial effect: the utility model by setting up threaded steel bushing on cylinder body, make the upper end closure of oil storage cylinder detachable, being convenient to the chassis development stage debugs the recovery damping of vibration damper and compression damping, effectively shorten the construction cycle, reduce exemplar fabricating cost, have ingenious, the structure of design simple, implement the features such as easy.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail:
As shown in Figure 1, the oil storage cylinder of car rear shock absorber has cylinder body 1, and the upper end of this cylinder body 1 is uncovered, and the wall thickness of cylinder body 1 is 1-1.5mm, and concrete thickness is determined according to actual needs.Be set with steel bushing 2 in the upper end of cylinder body 1, steel bushing 2 and cylinder body 1 interference fit, and fixed by brazing between steel bushing 2 and cylinder body 1.The wall thickness of steel bushing 2 is 2.5-3mm, and concrete thickness is determined according to actual needs.The end face of steel bushing 2 and the either flush of cylinder body 1, by conical surface transition between the end face of steel bushing 2 and outer peripheral surface, and be processed with screw thread on the outer peripheral surface of steel bushing 2.
Claims (4)
1. a car rear shock absorber oil storage cylinder, there is cylinder body (1), the upper end of this cylinder body (1) is uncovered, it is characterized in that: be installed with steel bushing (2) in the upper end of described cylinder body (1), and the outer peripheral surface of steel bushing (2) is provided with screw thread.
2. car rear shock absorber oil storage cylinder according to claim 1, is characterized in that: described steel bushing (2) and cylinder body (1) interference fit, and is fixed by brazing between steel bushing (2) and cylinder body (1).
