Abstract
The invention discloses a rear shock absorber. Damping springs (1) are arranged outside a damper assembly; the damper assembly is provided with a working cylinder (4) and a piston rod (5); a piston valve system (6) is arranged on the portion, where the piston rod (5) is located, of the working cylinder (4); the working cylinder (4) is divided by the piston valve system (6) into an upper cavity and a lower cavity; a guide base (7) is arranged between the piston valve system (6) and one end of the working cylinder (4); the guide base (7) is arranged in the working cylinder (4) and is in sealing contact with the piston rod (5) and the inner wall of the working cylinder (4); the piston rod (5) penetrates through the guide base (7); an inlet is formed in one end of the working cylinder; an oil seal cover (8) is arranged on the inlet; one part of the piston rod (5) penetrates through the oil seal cover (8) to be inserted in the working cylinder (4); one side of the guide base (7) is sleeved with a sealing oil seal (9); the sealing oil seal (9) is opposite to the oil seal cover (8).
Description
Technical field
The present invention relates to a kind of rear shock absorber.
Background technique
Due to the severe operating conditions of oil sealing in vibration damper, so very high to the oil sealing of oil sealing, gas confining and heat resistant requirements, if after the muddy water of occurring in nature enters vibration damper inside, working liquid capability can be caused to worsen and inner body excessive wear.Along with the operating time passes, in vibration damper, each parts and components work relationship worsens rapidly, and this vicious circle will sharply reduce the endurance quality of vibration damper, in oil sealing assembly process, for avoiding scratching oil seal lip, assemble not in place, oil sealing pilot hole or shaft design pay particular attention to.Vehicle shock absorber cold forming sealing process has strict requirement to finished product sealing, intensity and appearance quality.As sealing process is unreasonable, part can be made to occur surface comes off, crackle and surfacing are piled up, wrinkling.Under high speed and high pressure working state, oil sealing, guidance set are by axial float, cause resilient snubber earlier period damage, and more seriously, excessive thinning urceolus tube wall thickness, will reduce the tensile strength of vibration damper.What adopt in vibration damper at present is metal frame, because metal frame oil sealing requires higher internal-external circle concentricity requirement, otherwise the premature wear of oil seal lip can be caused, affect sealability and the life-span of oil sealing, if the turbidity test of oil sealing work system are bad, just as there being cooperation place between matching relationship part to add lapping paste, increase the weight of the generation of wearing and tearing, abrasive particle, change former matching relationship, cause and partially scratched or increased the weight of partially to scratch, once more increase the weight of wearing and tearing conversely, add abrasive particle, partially scratch vicious circle more very.
Summary of the invention
The invention provides a kind of rear shock absorber, it not only can improve oil sealing and gas confining effectively, and effectively can keep turbidity test.
Present invention employs following technological scheme: a kind of rear shock absorber, 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, 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, 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, one end of described clutch release slave cylinder is provided with import, oil seal cover is provided with in inlet, a part for piston rod is inserted in clutch release slave cylinder through oil seal cover, the side cover of guide holder has hermetic oil seal, hermetic oil seal is relative with oil seal cover.
Described oil seal cover is connected with sealing for cold forming between import.Described guide holder is connected with sealing for cold forming between hermetic oil seal.Described oil seal cover is tetrafluoroethylene oil seal cover.Described hermetic oil seal is set to unreinforced seal oil sealing.
The present invention has following beneficial effect: after have employed above technological scheme, one end of clutch release slave cylinder of the present invention is provided with import, oil seal cover is provided with in inlet, a part for piston rod is inserted in clutch release slave cylinder through oil seal cover, the side cover of guide holder has hermetic oil seal, hermetic oil seal is relative with oil seal cover, the turbidity test in clutch release slave cylinder can be kept like this, the present invention adopts exoskeletal oil sealing, oil sealing and envelope gas better effects if can be made like this, avoid oil sealing and must not there be the defect of coming unstuck or fitting loosely skeleton connecting part, the present invention is provided with oil seal cover, oil seal cover is tetrafluoroethylene oil seal cover, so not only oil seal cover is neither too hard, nor too soft, wear resistance is good, dust seal gas performance is greatly improved, it motorcycle vibration absorber is first Application, oil seal cover of the present invention is connected with sealing between import and between guide holder with hermetic oil seal for cold forming, and such cold forming sealing is with low cost, simple to operate, and can effectively avoid rubber seal overheating failure.
