Description
Technical field
It the utility model is related to vehicular shock absorber technical field, and in particular to a kind of damper.
Background technology
Damper (Absorber), concussion when being for suppressing to rebound after spring shock-absorbing and the impact from road surface.Extensively
It is general to be used for automobile, to accelerate the decay of vehicle frame and body vibrations, to improve ride of vehicle.
Damper includes the hydraulic damper with floating piston in cylinder, and this damper typically directly will be floating on the market
Piston is attached with barrel, and because piston is rubber, and domestic rubber is due to technique limitation, manufactured floating piston
Life-span is not grown, and will be failed using a period of time damper.
Utility model content
Technical problem to be solved in the utility model is to be directed to above-mentioned the deficiencies in the prior art,
A kind of damper is provided.
To achieve the above object, the utility model provides following technical scheme：A kind of damper, includes fuel tank,
Described fuel tank one end is connected with piston-rod assembly, and the piston-rod assembly is sealed with fuel tank junction by oil seal seat, institute
State fuel tank and be respectively equipped with suspension ring with piston-rod assembly, be provided with O-ring in the fuel tank, the O-ring is by inside fuel tank
It is separated into oil storage chamber and gas storage chamber, it is characterised in that：The O-ring is externally connected with floating piston, and the floating piston is in I-shaped
Shape, its left and right ends are respectively equipped with first chamber and second chamber, and piston is connected with the first chamber, and the O-ring connects
It is connected in second chamber, the piston-rod assembly includes piston rod, and described piston rod one end is connected with piston assembly, the work
Plug assembly includes the check valve set close to first chamber one end.
Using above-mentioned technical proposal, the floating piston in its fuel tank of traditional damper is O-ring, but it is domestic due to
The limitation of technique and material, O-ring service life often fall flat, and serve as floating piston and loosely with O-ring
Lean on, due to O-ring contact with fuel tank inwall and non-face contact, but linear contact lay, if gap between the two be present, then
Axial direction when O-ring moves with fuel tank is extremely difficult to parastate in ideal, and the floating piston that the utility model is set up
With first chamber and second chamber, O-ring is arranged in second chamber, because floating piston has certain length, because
This contact with fuel tank inwall contacts for face, can reach preferable parastate, so as to extend the service life of damper.
A kind of above-mentioned damper can be further arranged to：The one end of the check valve away from floating piston passes through cushion collar
Guider is connected with, the guider is connected in oil seal seat, and the guider is sheathed on piston rod by first sleeve, described
Oil seal seat is sheathed on piston rod by the second sleeve pipe.
Using above-mentioned technical proposal, device is directed to by first sleeve and the second sleeve pipe and is sheathed on piston rod with oil seal seat
On, due to first sleeve and the second sleeve pipe be present, piston rod slides gentler between guider and oil seal seat.
A kind of above-mentioned damper can be further arranged to：The first sleeve and the second sleeve pipe are DU bearings.
A kind of above-mentioned damper can be further arranged to：Telescopic dirt-proof boot is arranged with outside the piston rod.
The beneficial effects of the utility model are：Contact between floating piston and fuel tank contacts for face, substantially increases
The service life of floating piston in damper, and then extend the service life of damper, first sleeve and the second sleeve pipe are deposited
Make it that the motion of piston rod is more smooth.The utility model is described in further detail with reference to the accompanying drawings and examples.
Brief description of the drawings
Fig. 1 is the schematic perspective view of the utility model embodiment.
Fig. 2 is the floating piston arrangement schematic diagram of the utility model embodiment.
