Description
Technical field
The utility model relates to a kind of front damper with plastic dust pipe.
Background technology
Present front damper mainly comes damping, damping effect difference and inconvenience regulation by a compression spring, at damper
In, shank and bar cylinder are two parts individually processing, and when assembling, stream oriented device to be guaranteed is on same axial line,
But in reality, be truly realized at same axial line extremely difficult, therefore shank work when to front damper to oil sealing
Lateral pressure bigger, easily make oil sealing that the phenomenon of leakage of oil occurs, thus reduce the damping performance of damper.
Utility model content
The technical problems to be solved in the utility model is: for asking of solving that prior art in above-mentioned background technology exists
Topic, provides a kind of improved minimizing lateral pressure, good sealing effect, reduce oil leakage phenomenon generation with plastic dust pipe before
Damper.
The utility model solves its technical problem and be the technical scheme is that a kind of front damping with plastic dust pipe
Device, has aluminum barrel with aluminum barrel to the shank assembly coordinating, is provided with damper rod in aluminum barrel, and the two ends of damper rod is equipped with screw,
Damper rod is provided with straight-bar seat with the junction of aluminum barrel, and straight-bar seat is fixed with straight-bar, and one end of described shank assembly is provided with interior six
Silently, its other end is provided with piston component at angle, and shank assembly is arranged with long spring, long spring and interior hexagonal silently between be provided with
Bushing pipe, the outer surface of the opening part of described aluminum pipe is provided with plastic bushing, and its opening part is provided with close with the junction of shank assembly
Seal apparatus.
Further, described screw and aluminum barrel junction are provided with sealing ring, are provided with red copper pad at its step.
Further, described piston component includes piston, front damping spring and back-up ring, between described piston and back-up ring
Damping spring before being provided with, is provided with flexure strip, before described back-up ring and shank assembly inwall junction are provided with between front damping spring and piston
Piston ring.
Further, it is provided with spring shim between described bushing pipe and long spring.
Further, described aluminum barrel and interior hexagonal junction silently are provided with oil sealing.
The beneficial effects of the utility model are, simple in construction of the present utility model, easy to use, reduce lateral pressure, close
Envelope effect is good, reduces the generation of oil leakage phenomenon, improves damping performance further, and service life is long, it is not necessary to often changes, reduces into
This.
