A kind of vibration damper
Technical field
The utility model relates to a kind of auto parts machinery, particularly a kind of vibration damper.
Background technique
The vibration damper that automobile is used is one of most important parts in automobile chassis system, its main structure has clutch release slave cylinder and installs piston rod, guide sleeve, dust-proof cover and the oil sealing on clutch release slave cylinder, all generally by bolt, dust-proof cover to be fixed on piston rod, in addition on bolt also for the entrucking annex being connected with outside automobile mechanism is installed.Adopt this kind of structure, because vibration damper in use can shake, and bolt one carrys out insufficient strength, and two can be in vibrations occurs easily causing the situation of loosening or matching gap bolt looseness or come off, thereby affects the stability of vibration damper work.
Model utility content
Technical problem to be solved in the utility model is for the deficiencies in the prior art, and a kind of vibration damper is provided.
To achieve these goals, the measure that the utility model is taked:
A kind of vibration damper, the upper rings and the lower lift ring that comprise vibration damper body, be connected with vibration damper body, described vibration damper body, upper rings and lower lift ring are integrated and are welded, in vibration damper body, be provided with clutch release slave cylinder, clutch release slave cylinder inner sleeve has piston rod, clutch release slave cylinder overcoat has oil storage cylinder, between described clutch release slave cylinder upper end and piston rod, be provided with guider, between guider and piston rod, cover has guide sleeve, the lower end of piston rod is provided with piston sub-assembly, in clutch release slave cylinder, lower end correspondence is provided with sub assembly of bottom valve, and described vibration damper body lower end is provided with bottom;
The top of described guider is provided with oil sealing base, is provided with common outside framework oil seal in oil sealing base, and oil sealing base overcoat has dustproof sleeve pipe, and dustproof sleeve pipe peripheral hardware has dust cover;
In described piston sub-assembly, be provided with piston, the lower end of piston is provided with rebuilt valve, between piston and rebuilt valve, be provided with recovery valve block, the upper end of piston sub-assembly is provided with piston limit packing ring, between piston limit packing ring and piston, be provided with successively flowing valve pad, circulation valve block and flow-through opening valve block, the lower end of piston sub-assembly is provided with locking nut, is provided with rebuilt valve pad between locking nut and rebuilt valve;
In described sub assembly of bottom valve, be provided with foot valve seat, foot valve seat is provided with bottom valve body, between foot valve seat and bottom valve body, be provided with successively compression throttling valve block and compression valve block, the upper end of sub assembly of bottom valve is provided with bottom valve retainer, between bottom valve retainer and bottom valve body, is provided with bottom valve spring;
On described upper rings, cover has upper rings rubber bushing, and on lower lift ring, cover has lower lift ring rubber bushing.
The beneficial effects of the utility model: the utility model compact structure, good stability, reliability is high, be not easy to occur situation loosening and that come off, more stable to fixing of dust cover, also improved the reliability under vibration damper working state, reduced the rate of breakdown of accessory, extended the working life of accessory simultaneously.
