Description
Technical field
The utility model relates to a kind of front damper of motorcycle, especially relates to the interchangeable front shock absorber of a kind of motor bike.
Background technology
Motorcycle vibration absorber is mainly used in buffering and impacts the impact shock that causes the driver because of ground in the face of motor bike, to improve comfort of drivers and passengers.Front damper of motorcycle mainly is made up of damping cylinder, piston rod, damping spring, recoil spring, front fork tube etc., after motor bike is subjected to external impacts, front fork tube moves downward, damping spring bears pressure, the part fluid of lower oil cavitie is washed open in the ring gear valve block inflow transition oil pocket in the damping cylinder simultaneously, the fluid of another part then oilhole by underpart of the piston rod and middle part flows into upper oil cavitie and transition oil pocket in the front fork tube respectively, plays the effect of compression damping.When front shock absorber restores, under the elastic force effect of damping spring, the front fork tube upward movement, fluid in the transition this moment oil pocket is by the lower oil cavitie in the oilhole inflow damping cylinder at piston rod middle part, and the fluid of lower oil cavitie produces and restores damping by the lower oil cavitie of piston rod interstitial hole inflow damping cylinder in the front fork tube.But disclosed front shock absorber, the anterior sealing with front fork tube of its damping cylinder is to realize by oil sealing, because oil sealing and front fork tube are running-fit, so oil sealing is a consumable accessory, therefore in changing the oil sealed process, to tear absorber main body open earlier, could change oil sealing, change very inconvenience of oil sealing.
Summary of the invention
The purpose of this utility model provides and a kind ofly can reduce front fork tube and damping cylinder frictional resistance, changes the oil sealing interchangeable front shock absorber of motor bike easily.
The utility model is that the technical scheme that achieves the above object is: the interchangeable front shock absorber of a kind of motor bike, comprise damping cylinder, be connected the piston rod on the damping cylinder bottom, extend to the front fork tube in the damping cylinder, and be arranged on damping spring in the front fork tube, piston, recoil spring, pad, ring gear valve block and spacer, the end of front fork tube is connected with plug, and piston is arranged on the end of piston rod, it is characterized in that: described damping cylinder outside face has anodic oxide coating, and lining is housed down successively from bottom to top in the damping cylinder, Lower shaft sleeve, last lining and Upper shaft sleeve, front fork tube and Lower shaft sleeve and Upper shaft sleeve bearing fit, fastener passes damping cylinder and is connected with piston rod with pole socket, described oil-sealing sleeve is screwed in the upper end side of damping cylinder, and be arranged on the interior oil sealing of oil-sealing sleeve is against damping cylinder by spacer ring port, oil sealing is spacing by the back-up ring that is arranged on the oil-sealing sleeve, and the outside of oil-sealing sleeve also is connected with cover of dust.
Damping cylinder of the present utility model makes the damping cylinder outside have hard anodization protective cover by anodic oxidation treatment, therefore can coat multicolour on damping cylinder according to customer requirements, changes the dull for many years color of motor bike.The oil-sealing sleeve of utility model and damping cylinder adopt demountable structure, as long as therefore pull down oil-sealing sleeve, just can take out the oil sealing that is installed in the oil-sealing sleeve, convenient and swift replacing oil sealing.The utility model adopts Upper shaft sleeve and Lower shaft sleeve and front fork tube to be connected, can guarantee the quality of fit between front fork tube and the axle sleeve, reduce the motion frictional resistance between upper and lower axle sleeve and the front fork tube, make the front fork tube crank motion nimbly and freely, change the comfort level of bumper, minimizing front fork tube appearance is pulled oil seal lip, reduces the front shock absorber oil spill rate significantly, and the service life of prolongation front shock absorber
