Abstract
The utility model discloses an integrated air bag rear shock absorber, which comprises an oil storage tank, a working cylinder, a shock absorbing cushion, a shock absorbing spring, a lower joint and a connecting rod, wherein the inner side of an oil storage cavity of the oil storage tank is provided with an air-pressure chamber which is composed of an air bag, a sealing cover and a dustproof cover; the oil storage cavity of the oil storage tank is communicated with the working cylinder through an oil through hole; a rod body of the connecting rod which is inserted into the working cylinder is orderly sheathed with a buffering cushion, a guiding seat, an oil seal lower washer, an oil seal and an oil seal washer; the oil storage tank and the working cylinder are an integral structure; the outer side of the oil seal washer in the working cylinder is provided with a circlip for hole. Compared with the original structure, the utility model not only has better tightness, but also reduces the process of installation. Making use of the circlip for hole to replace a rolling slot and a flanging of the original working cylinder, the utility model has the advantages of easies installation and disassembly. The utility model can conveniently carry out maintenance for the inner members of the working cylinder, and the working performance of the whole mechanism is ensured.
Description
Technical field
The utility model relates to a kind of rear shock absorber that is used on automobile or the motorcycle, especially integrated type air bag rear shock absorber.
Background technique
At present, the vibration damper that is used for automobile or motorcycle mainly is divided into spring hydraulic formula, oil gas mixing spring and air bag vibration damper.Spring hydraulic formula, oil gas mixing spring type shock absorber are blended in the same active chamber owing to oil gas, spring hydraulic formula vibration damper easily produces the motion idle running when work, oil gas mixing spring type shock absorber is being worked the regular hour, damping oil easily produces emulsion, influences the vibration damper performance.The CN2500513Y of State Intellectual Property Office has announced a kind of air bag vibration damper, constitute by parts such as oil tank, clutch release slave cylinder, beam, damping spring, lower contact and connecting rods, be threaded between oil tank and the clutch release slave cylinder, and be communicated with by oil through, connecting rod one end inserts in the clutch release slave cylinder, be set with cushion pad, guide holder, oil sealing lower gasket, oil sealing and oil sealing gasket successively on the shaft in connecting rod inserts clutch release slave cylinder, in order to limit the displacement of guide holder, assemble clutch release slave cylinder inner structure part, adopting special plane that the clutch release slave cylinder slot rolling is processed; Position-limiting action also plays to in-flanges in clutch release slave cylinder outer end opening place.This air bag vibration damper becomes the active chamber of oil gas hybrid working chamber into two isolation, has solved vibration damper and has easily produced idle running and produce the problem of emulsification.But there is following defective in this vibration damper on structural feature:
1, oil tank is threaded with clutch release slave cylinder, and this tolerance fit has certain interval, and sealing is relatively poor, is easy to generate the gas leakage leakage of oil; For ensureing its sealing, O type circle is housed in the joint usually, but the installation difficulty of O type circle is bigger, in the process of installing, scratch O type circle in addition easily, make it lose seal action;
2, after in a single day cushion pad, guide holder, oil sealing lower gasket, oil sealing and oil sealing gasket are loaded onto, if vibration damper is installed on the former car, in the movement process, when the vibration damper performance issue need be safeguarded, can only destructive dismantle, can't keep in repair after the dismounting, make vibration damper integral body scrap, waste bigger;
3, because the clutch release slave cylinder wall thickness is thinner, generally have only about 1mm, in the process of assembling or use, be damaged easily, thereby when causing interior piston assembly of clutch release slave cylinder and clutch release slave cylinder to move back and forth, produce clamping stagnation, even produce vibration damper " locking " phenomenon, influence the performance of whole vibration damper.
The model utility content
For solving above technical problem, the purpose of this utility model is to provide the integrated type air bag rear shock absorber of a kind of good airproof performance, easy to maintenance, reliable performance.
The technical solution of the utility model is as follows: a kind of integrated type air bag rear shock absorber, comprise oil tank, clutch release slave cylinder, beam, damping spring, lower contact and connecting rod, wherein be equipped with by air bag in the oil storage chamber of oil tank, the air-pressure chamber that sealing cover and dust cover constitute, and the oil storage chamber of oil tank is communicated with clutch release slave cylinder by oil through, be set with cushion pad successively on the shaft in connecting rod inserts clutch release slave cylinder, guide holder, the oil sealing lower gasket, oil sealing and oil sealing gasket, its key is: described oil tank and clutch release slave cylinder are monolithic construction, at the porose circlip of using of the arranged outside of clutch release slave cylinder inner oil seal packing ring.
In air bag, be marked with pressurized gas, in the oil storage chamber in the air bag outside and be marked with damping oil in the clutch release slave cylinder, form damper with two isolated chamber.
The inwall of described clutch release slave cylinder has annular groove, in this annular groove circlip for hole is housed.
Dust cover is equipped with in the outlet port of described clutch release slave cylinder outer end.
The utility model is after changing monolithic construction into by being threaded between oil tank and the clutch release slave cylinder, better tightness not only, and reduced installation procedure; Because oil tank and clutch release slave cylinder are monolithic construction, the clutch release slave cylinder wall thickness increases, can be increased to the 3mm left and right thickness, easy damaged clutch release slave cylinder wall surface not in the process of assembling cushion pad, guide holder, oil sealing lower gasket, oil sealing and oil sealing gasket, thus ensured the performance of entire mechanism; And it is spacing to adopt circlip for hole to carry out, and has cancelled slot rolling and overturning process when the assembling work cylinder, and it is easier to mount and dismount, and manufacturing efficiency improves.In addition,, also can dismantle from the clutch release slave cylinder external end head easily, the clutch release slave cylinder inner piece is keeped in repair even damaging appears in the clutch release slave cylinder inner body.
The utlity model has compact structure, good sealing effect, easy installation and removal, service behaviour advantage such as can be protected.
