Description
Technical field
The utility model relates to a kind of hydraulic damper of Motor Vehicle, especially relates to a kind of two guiding hydraulic damper that are used for the motorcycle rear portion.
Background technique
Hydraulic damper behind the present disclosed motorcycle is decay a impact endurance test shock in the vehicle driving process of flow of liquid produces when aperture in elastic buffer by spring and the oil cylinder damping.Owing to type frequently reciprocating between piston rod and the oil sealing, be subjected to the influence of road conditions again, in the vehicle driving process so vibration damper is in than bad working environment.General rear shock absorber, only rely on the guide sleeve between piston rod and the cylinder body in the vibration damper telescopic process, to play guiding and position-limiting action, to such an extent as to cross shear concentrates on piston rod and cylinder body place, therefore make piston rod axially reciprocating instability after stressed, cross shear causes outside framework oil seal to wear and tear too early, cause fluid to reveal, the attenuation function of vibration damper is descended, influence the usability and the working life of vibration damper.
Goal of the invention
It is reliable that technical problem to be solved in the utility model provides a kind of usability, can improve two guiding hydraulic damper in working life.
The technological scheme that the utility model will solve the problems of the technologies described above is: a kind of two guiding hydraulic damper, comprise oil cylinder, damper cylinder, piston, piston rod, damping spring and Sealing, the oil cylinder post is connected with following connection part with last connection part respectively with damper cylinder, damping spring is arranged on the spring seat in the outer dust-proof cover and the damper cylinder outside, it is characterized in that: the lip seal that is contained in the oil resistant dust-proof cover one end on the damper cylinder is contained on the shock structure, and the bottom of close damper cylinder end and oil cylinder is provided with outer guide sleeve and openings lead cover; The piston rod that is connected down on the connection part is equipped with buffing pad, and piston rod passes in-oil cylinder outside framework oil seal, guide sleeve, the damping spring that resets in the sealing that piston rod is play the guiding role, and is connected with little spring, valve block, piston sheet and piston in turn.
After the utility model is implemented technique scheme: owing to position guiding by guide sleeve between the periphery of oil cylinder and the damper cylinder, it is simple in structure, vibration damper suffered cross shear major part in telescopic process is transferred between damper cylinder and oil cylinder, therefore significantly reduced the cross shear between piston rod and the oil cylinder, make the stability of piston rod axially reciprocating better, avoided in the piston rod working procedure causing phenomenon to the oil sealing premature damage because of cross shear, reduce the vibration damper oil leakage phenomenon, improved the usability and the working life of vibration damper.
