Abstract

The utility model relates to a shock-absorber used for a light duty car or a truck. The top end of an outer cylinder is welded with a joint, and the upper end of the joint is provided with an inner thread hole. A piston rod is successively provided with a ring rubber ring, a washer, a spring, a gland, etc. A press cover is connected with the upper end of the joint by a thread, and the outer cylinder is provided with an oil feeding hole at least. The seal manners of the oil feeding hole can be a closed drawing rivet seal, a screw seal and a one-way valve seal. The utility model has the advantages of simple structure, convenient maintenance, and repetitive use. The utility model can solve the problem of oil leakage of the shock-absorber well, and the service life can be prolonged for more than five times.

Description

A kind of automobile absorber

The utility model relates to a kind of automobile shock-absorber, exactly is a kind of vibration damper that is used for light-duty sedan-chair, truck.

At present, the used vibration damper of general-utility car mostly is disposable, is leakage of oil and influence the subject matter in vibration damper working life.Chinese patent " new-type damper for light car " (ZL95220696.X), though solved the repeatedly used problem of vibration damper, structure is comparatively complicated, and can not solve the problem of vibration damper leakage of oil well.

Goal of the invention of the present utility model is to provide a kind of and can uses repeatedly, and is simple in structure, and can solve the automobile absorber of vibration damper leakage of oil preferably.

The technical solution of the utility model is achieved in that its structure comprises piston rod, gland, spring, packing ring, joint, ring-like cushion rubber, urceolus etc.Be welded with joint on the urceolus top, upper end of joint has interior threaded hole; Ring-like cushion rubber, packing ring, spring, gland are housed on the piston rod successively; Gland has outside thread, is threaded with the interior threaded hole of upper end of joint.

On urceolus, be provided with an oil hole at least, the air-tight manner of oil hole can: the one, with the sealing of closed pulling rivet; The 2nd, on the outer tube wall of oil hole, be welded with the screw seat, on the screw seat pad is arranged, seal with screw; The 3rd, on the outer tube wall of oil hole, be welded with the screw seat, seal with one-way valve.

The utility model is simple in structure, and maintenance, easy maintenance are with low cost, can solve the leakage of oil problem of vibration damper preferably, can increase the service life more than 5 times.
