Description
Technical field
The utility model relates to a kind of inflatable rare vibration damper.
Background technique
At present, the domestic rear shock absorber produced voluntarily mainly contains spring hydraulic, air-fuel mixture spring damper and inflatable rare vibration damper, the above two features be air-fuel mixture in same working room, inflatable rare vibration damper is filled with pressurized gas on the above two basis.When travelling on the road surface that height is different by bus, ground impacts in the face of wheel generation is fierce, makes the vibrations of driving, taking advantage of personnel to feel strong, produces tired and uncomfortable.In addition, spring hydraulic formula rear shock absorber is due to when moving, and connecting rod occupies certain space by going deep into clutch release slave cylinder, and fluid compensates not in time, causes this vibration damper easily to produce idle running phenomenon.Meanwhile, when vibration damper uses some cycles, damping oil easily produces emulsification, has a strong impact on product performance.Although air-fuel mixture formula rear shock absorber avoids idle running phenomenon in a way, owing to being air-fuel mixture, still keep away the generation of unavoidable damping oil emulsion.
Summary of the invention
The utility model provides a kind of inflatable rare vibration damper, and its inflatable rare vibration damper owing to being filled with pressurized gas, and adopts oil gas isolation technology, solves idle running phenomenon and oil emulsifying problem that conventional rear shock absorber runs into.
The utility model have employed following technological scheme: a kind of inflatable rare vibration damper, it is provided with damper assembly, damping spring is provided with outside damper assembly, installing ring and lower installing ring is respectively equipped with at the two ends of damper assembly, described damper assembly is provided with clutch release slave cylinder and piston rod, a part for piston rod is inserted and is inserted in clutch release slave cylinder by the side of clutch release slave cylinder, the part being positioned at clutch release slave cylinder at piston rod is provided with piston valve system, clutch release slave cylinder is divided into epicoele and cavity of resorption by piston valve system, guide holder is provided with between piston valve system and one end of clutch release slave cylinder, the opposite side of clutch release slave cylinder is set to fuel tank, guide holder contacts for sealing respectively with between piston rod and clutch release slave cylinder inwall in clutch release slave cylinder, piston rod is through guide holder, the outer ring of described piston valve system is provided with floating piston, air-pressure chamber is provided with between floating piston and clutch release slave cylinder, pressurized gas are filled with in air-pressure chamber, hydraulic chamber is provided with between floating piston and guide holder, upper installing ring is provided with inflation inlet, inflation inlet is connected with in clutch release slave cylinder by pipeline, gas charging valve assembly is provided with in inflation inlet.
The outside of described fuel tank is provided with spring adjusting seat, between spring adjusting seat and fuel tank, be provided with guard shield, and guard shield is fixed on the outer wall of fuel tank.Be provided with joint shaft bearing in described lower installing ring, lower installing ring is connected with frame of motorcycle by joint shaft bearing.The valve block diameter of described piston valve system both sides reduces rear stepped setting from inside to outside.
The utility model has following beneficial effect: after have employed above technological scheme, the utility model arranges a gas charging valve assembly on upper installing ring, inflate after vibration damper has assembled like this, also can inflate in real time and be vented, use convenient, different loads and different road conditions can be made all to reach comfortable effect.Air-pressure chamber is provided with between the utility model floating piston and clutch release slave cylinder, pressurized gas are filled with in air-pressure chamber, hydraulic chamber between floating piston and guide holder is marked with damping oil, the damper with two isolation active chambers can be formed like this, due to floating piston one, side is pressed with pressurized gas, forces the fluid in damper to be full of the upper and lower chamber of piston valve system, thus realizes fluid compensate function, overcoming can the idle running phenomenon that operationally produces of conventional rear shock absorber, and the shortcoming of damping oil emulsification.When by bus be uneven road surface travels time, the hyperbaric chamber due to this vibrational power flow, thus alleviate the vibrations of vehicle body, work as load change, piston rod stretches in dampening chamber, causes the Volume Changes of plenum chamber, the pressure change of generation is proportional with load.Therefore, meet the different road conditions of different loads and all can reach comfortable effect, the utility model compact structure, economical and practical in addition, and reliable performance is stablized, the shortcoming of idle running phenomenon that conventional rear shock absorber operationally produces and the easy emulsification of damping oil can not only be overcome, and, fully can alleviate vehicle body vibrations, reach good damping effect, and good manufacturability, take up space after entrucking few.The outside of the utility model fuel tank is provided with spring adjusting seat, guard shield is provided with between spring adjusting seat and fuel tank, guard shield is fixed on the outer wall of fuel tank, the precompression of damping spring can be regulated by adjusting seat, fuel tank outer wall welds a guard shield, can be avoided the friction of adjusting seat and fuel tank like this, improve the working life of fuel tank.Under the utility model, installing ring is connected with frame of motorcycle by joint shaft bearing, and such joint shaft bearing internal void is very little, and the machining accuracy of each part is higher, and self-align ability is strong, and therefore, can reduce the consumption of lubricant oil, lubricated maintenance is comparatively saved trouble; Secondly, the bearing capacity of joint shaft bearing is large, and friction factor is little, easy to use and maintenance.The valve block diameter of the utility model piston valve system both sides reduces rear stepped setting from inside to outside, the pressure classification of hydraulic oil is reduced, progressively decay, can prevent from like this producing bubble in fluid, avoid producing noise, also improve the quality of fluid, these bubbles flow to pressure higher position with liquid and can instantaneously crush simultaneously, generation noise simultaneously.
