Abstract
The utility model relates to a bumper shock absorber before compound shell type in area, including a handle pole and a pole section of thick bamboo, offer the pole chamber that is used for holding the handle pole in the pole section of thick bamboo, the one end of handle pole is inserted at the pole intracavity of a pole section of thick bamboo and form the clearance fit between the pole section of thick bamboo, the open end in pole chamber is provided with the oil blanket chamber, the oil blanket intracavity is provided with preceding oil blanket, oil blanket intracavity side is provided with the bush chamber, the bush intracavity is provided with compound bush, compound bush cup joints on the handle pole. By the compound bush that sets up, but a handle pole and a pole section of thick bamboo are in same axle center position, reduce the lateral pressure of bumper shock absorber handle pole pair oil blanket in the motion process, reduce the phenomenon that damper oil sealed the oil leak, further promote damping performance.
Description
Technical field
The utility model relates to a kind of band compound shell type front shock absorber.
Background technique
In vibration damper, handle bar and bar cylinder are two parts processed separately, to guarantee that stream oriented device is on same shaft axis when assembling, but in reality, to really accomplish at same shaft axis very difficult, therefore handle bar is larger to the lateral pressure of front shock absorber to oil sealing when work, easily makes oil sealing occur the phenomenon of leakage of oil, thus reduces the damping performance of vibration damper.
Model utility content
The technical problems to be solved in the utility model is: overcome the deficiencies in the prior art, provides a kind of band compound shell type front shock absorber.
The utility model solves the technological scheme that its technical problem adopts: a kind of band compound shell type front shock absorber, comprise handle bar and bar cylinder, offering the bar chamber for holding handle bar in described bar cylinder, coordinating with formation activity between bar cylinder in the bar chamber that one end of described handle bar is inserted in bar cylinder;
The opening end in described bar chamber is provided with oil sealing chamber, is provided with Front oil seal in described oil sealing chamber, is provided with lining chamber inside described oil sealing chamber, and be provided with composite bush in described lining chamber, described composite bush is socketed on handle bar.
Further, the inner side in described lining chamber is formed with the adjustment chamber of doing micro-swing for handle bar.
Further, between described oil sealing chamber and lining chamber, be provided with back-up ring chamber, in described back-up ring chamber, be provided with oil seal collar; The outside in described oil sealing chamber be provided with jump ring chamber, in described jump ring chamber, spacing jump ring is installed.
Further, the opening in described bar chamber is provided with dust-proof cover, and described dust-proof cover is connected with bar cylinder.
The beneficial effects of the utility model are: rely on the composite bush arranged, handle bar and bar cylinder are in same shaft core position, reduce vibration damper at the lateral pressure of movement process medium thick shank to oil sealing, reduce the phenomenon of oil seal for shock damper leakage of oil, promote damping performance further.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further illustrated.
Fig. 1 is the schematic diagram of the utility model vibration damper;
Fig. 2 is the partial enlarged drawing at A place in Fig. 1;
Wherein, 1, handle bar, 2, bar cylinder, 3, composite bush, 4, Front oil seal, 5, regulate chamber, 6, oil seal collar, 7, spacing jump ring, 8, dust-proof cover.
Embodiment
By reference to the accompanying drawings the utility model is further described now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, and therefore it only shows the formation relevant with the utility model.
As shown in Fig. 1 Fig. 2, a kind of band compound shell type front shock absorber, comprising handle bar 1 and bar cylinder 2, offering the bar chamber for holding handle bar 1 in bar cylinder 2, coordinates in the bar chamber that one end of handle bar 1 is inserted in bar cylinder 2 with formation activity between bar cylinder 2.
The opening end in bar chamber is provided with oil sealing chamber, is provided with Front oil seal 4 in oil sealing chamber, is provided with lining chamber inside oil sealing chamber, is provided with composite bush 3 in lining chamber, and composite bush 3 is socketed on handle bar 1.
The inner side in lining chamber is formed with the adjustment chamber 5 of doing micro-swing for handle bar 1.The length in chamber 5 is regulated to be greater than oil sealing chamber and lining cavity length sum.Because composite bush 3 has certain elasticity, when handle bar 1 is stressed do micro-swing time, handle bar 1 can adjustment chamber 5 in move, avoid handle bar 1 to rupture because of defect swing space.
Be provided with back-up ring chamber between oil sealing chamber and lining chamber, in back-up ring chamber, be provided with oil seal collar 6; The outside in oil sealing chamber be provided with jump ring chamber, spacing jump ring 7 is installed in jump ring chamber.Spacing jump ring 7 limits oil sealing in oil sealing chamber.
The opening in bar chamber is provided with dust-proof cover 8, and dust-proof cover 8 is connected with bar cylinder 2.
The utility model, rely on the composite bush 3 arranged, but handle bar 1 and bar cylinder 2 is in same shaft core position, reduces the lateral pressure of vibration damper at movement process medium thick shank 1 pair of oil sealing, reduces the phenomenon of oil seal for shock damper leakage of oil, promote damping performance further.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this model utility technological thought, can carry out various change and amendment completely.The technical scope of this model utility is not limited to the content on specification, must determine its technical scope according to right.
