Abstract
The utility model discloses a rear shock absorber with an air chamber. The utility model aims at providing a rear shock absorber which is provided with an air chamber in the shock absorber, is simple and compact in a structure, and is low in manufacturing cost. The shock absorber of the utility model comprises a working cylinder, an oil chamber in the working cylinder, a spring outside the working cylinder, and the air chamber, wherein the air chamber is arranged in an air cylinder in the shock absorber and in a straight line with the working cylinder. The air cylinder is connected with the working cylinder through a joint, and an inner hole of the joint is communicated with an opening of the oil chamber in the working cylinder through a damping hole on a damping valve sheet. A piston on which a sealing ring is sheathed is arranged between the air chamber in the air cylinder and the oil chamber. The utility model is suitable for automobiles and various pedal type or bestriding type motorcycles.
Description
Technical field
The utility model relates to the rear shock absorber of motor bike, particularly a kind of rear shock absorber of motorcycle with air chamber.
Background technology
The rear shock absorber of motorcycle that generally uses in the market is spring type shock absorber, its oil, gas are blended in the same clutch release slave cylinder, damping oil can not be filled with the clutch release slave cylinder volume, be easy to generate the idle running phenomenon of piston lever of reducer motion, in addition, when the road conditions of travelling of motor bike are relatively poor, the vibrations of wheel are bigger, bumper internal damping oil can produce bubble with the air-blending vibrations, has influence on the damping capacity of bumper, causes damping effect relatively poor.Mix adverse effect for overcoming bumper oil gas, people have carried out a lot of improvement to it, it is 02221273.6 that a kind of patent No. is wherein arranged, name is called the utility model patent of " air sac rear shock absorber ", the clutch release slave cylinder external parallel of this utility model in the bumper grease chamber is connected to a storage tanker, storage tanker is interior by air bag, seal cover cap and cover of dust constitute air-pressure chamber, thereby reach oil, the effect that gas separates, but this kind structure is because the gas tank volume is big and expose the inconvenience that causes some fit on, particularly on the pedal vehicle, use difficulty, in addition, when unexpected situations such as motor bike appearance inclination, external storage tanker is impaired easily, and adopt the bumper manufacturing of this structure complicated, cost is higher, certainly, the technical scheme that this utility model provided a kind of good method that solves the prior art defective of can yet be regarded as.
Summary of the invention
The purpose of this utility model is to solve above-mentioned deficiency, provides that a kind of air chamber is built in the bumper, rear shock absorber simple in structure, applied widely.
The technical scheme that its technical matters that solves the utility model adopts is:
A kind of rear shock absorber with air chamber, comprise grease chamber, outer spring and the air chamber of clutch release slave cylinder in clutch release slave cylinder, the clutch release slave cylinder, air chamber be built in the bumper with clutch release slave cylinder cylinder in alignment in, cylinder is connected with clutch release slave cylinder by joint, communicates by the damping hole on the damper valve plate between grease chamber's opening of the endoporus of joint and clutch release slave cylinder; Air chamber in the described cylinder be by cylinder piston and on the seal ring sealing that is with form, also can be the enclosure space that air bag and gasbag seat constitute.
The beneficial effects of the utility model are: (1) grease chamber separates with air chamber, fill with damping oil in the grease chamber, overcome the idle running phenomenon of piston lever of reducer motion, when the road conditions of travelling are relatively poor, can not shake damping capacity and the damping effect that has influence on bumper because of damping oil and air-blending; (2) because the existence of air chamber is arranged, when the road surface produced impact to wheel, the volume of air chamber changed, and has alleviated the vibrations of vehicle body, has improved the effect of damping and the comfort of driving; (3) air chamber is built in the upper end of clutch release slave cylinder in the bumper, makes whole bumper compact conformation, good looking appearance, installation dimension does not change, and still can be suitable for various types of motor bikes; (4) simple in structure, low cost of manufacture.
Description of drawings
Below in conjunction with accompanying drawing the utility model is done concrete detailed description the in detail.
Fig. 1 is the structural representation of a kind of embodiment of the utility model;
Fig. 2 is the structural representation of the another kind of embodiment of the utility model;
Fig. 3 is the structural representation of the third embodiment of the utility model;
The specific embodiment
With reference to Fig. 1, a kind of rear shock absorber with air chamber comprises clutch release slave cylinder 1, there are grease chamber 2, clutch release slave cylinder that spring 3 is arranged in the clutch release slave cylinder outward, air chamber 4 be built in the bumper with clutch release slave cylinder 1 cylinder 5 in alignment in, joint 6 and cylinder 5 inwalls are welded to connect with clutch release slave cylinder 1 cylindrical for being threaded, and communicate by the damping hole on the damper valve plate 11 between the endoporus 9 of joint 6 and the grease chamber's opening 10 of clutch release slave cylinder 1, there is piston 7 air chamber 4 and 2 of grease chambeies in the cylinder 5, are with seal ring 8 on the piston 7.
The utility model is filled with damping oil in grease chamber 2, in air chamber 4, gas is arranged, when motor bike travels in the relatively poor highway section of road conditions, because the impact that the road surface produces wheel, piston rod 13 compression spring 3 and upward movements, damping oil in the clutch release slave cylinder 1 produces shock damping action by the damping hole on the damper valve plate 11, promotes the gas in piston 7 compression air chamber 4; When piston rod 13 returns, the damping oil that enters in the cylinder 5 is back to grease chamber 2 by the damping hole on the damper valve plate 11 again.Owing to the existence of top, grease chamber air chamber, can improve the damping effect of bumper, alleviate the vibrations of vehicle body greatly, alleviate the sense of fatigue that bumpy sections is travelled.
With reference to Fig. 2, in air chamber 4, installed recoil spring 12 additional, can further improve the damping effect of vehicle body when load-bearing, suitable needs drag the vehicle of cargo to use.
With reference to Fig. 3, the enclosure space that the air chamber 4 in the cylinder 5 is constituted for air bag 14 and gasbag seat 15, the principle of work of its technical scheme is identical with embodiment shown in Figure 1, only is out of shape in another of closed air chamber 4.
Certainly, the air chamber of built-in isolation is not only applicable to rear shock absorber with effect that reaches oil, gas separation and the method that improves the damping performance of bumper on bumper, goes for front shock absorber yet, only needs to do respective change according to the structure of preceding damping and gets final product.
