Abstract
The invention provides a motorcycle damper damping working cylinder which comprises a circular-pipe-shaped working cylinder body. A guiding base is arranged at one end of the working cylinder body. The other end of the working cylinder body is connected with a bottom valve body. A connecting rod penetrates through the guiding base and extends into the working cylinder body, and the connecting rod is connected with a piston body. A buffering spring is arranged between the guiding base and the piston body. Damper oil is injected into the working cylinder body. The motorcycle damper damping working cylinder is characterized in that an oil exhaust hole is formed in the side wall of the working cylinder body between the guiding base and the piston body. The oil exhaust hole is added in the cylinder body of the damper working cylinder, accordingly, during damper working, oil of an oil cavity on the outer portion of the damper working cylinder can enter an inner high-pressure oil cavity smoothly and quickly, and the fact that restored damping force is stabilized in the required fluctuation range can be guaranteed.
Description
Technical field
The present invention relates to motorcycle damping device field, particularly relate to a kind of inversion type front damping device for motorcycle.
Background technique
The application of inversion type front buffer gear in motorcycle in motorcycle is very general, and it plays supporting vehicle body, transmitting tractive power, and the safety travelled with vehicle is closely bound up; It is again the quality of performance part, damping effect simultaneously, also can have an impact to the comfort of driver and passenger.The structure of existing inversion type front buffer gear, primarily of compositions such as piston rod combination, clutch release slave cylinder, bottom valve body, damping spring, breeches pipe, support tube, sleeve and end cylinders, piston rod combination is assemblied in clutch release slave cylinder with bottom valve body and forms built-in damper, damping spring is positioned at breeches pipe, two ends are between end cylinder and positioning pipe, and clutch release slave cylinder is built with damping oil.When motorcycle runs, piston rod is combined in clutch release slave cylinder and moves up and down, and urceolus also moves up and down relative to breeches pipe simultaneously, realizes damping shock absorption by the effect of built-in damper and damping spring.Its deficiency is: because connecting rod adopts machine riveting method, because upside-down connecting rod is longer, be easy to bending deflection after riveted joint, make its straightness accuracy overproof, and need design specialized frock, this assembly method cost is high, and efficiency is low.And when the road surface that motorcycle runs into projection is subject to impacting, connecting rod is also thereupon constantly reciprocating up and down, when connecting rod moves upward, now, piston valve is rushed to open upwards, because damper clutch release slave cylinder peripheral space is filled with oil, and seal is formed with vacuum in clutch release slave cylinder, the oil of clutch release slave cylinder exocoel is difficult to enter into inner chamber immediately by normal open hole on valve block and bottom valve sheet, causes vibration damper long duration undamped, travelling comfort is poor, and recovery damping force portion stablizes.
Summary of the invention
For achieving the above object and other relevant objects, the invention provides a kind of inversion type front damping device for motorcycle, comprise connecting rod, described connecting rod one end is stretched in working cylinder through guide holder, assemble valve seat, spring sheet, valve block and piston body successively, and fixed by self-locking nut; Be provided with damping spring between described guide holder and piston body, the clutch release slave cylinder sidewall between described guide holder and piston body is provided with oil drainage hole.Employing self-locking nut is fixed, and connecting rod piston can be made to combine assembling more simply, and manufacturing efficiency is higher; Connecting rod not easily produces bending, increases oil drainage hole and both ensure that the oil of the outside oil pocket of damper clutch release slave cylinder can enter into high-voltage oil cavity smoothly fast, in turn ensure that recovery damping force is stabilized within the wave range of requirement.
Further, the diameter of described oil drainage hole is between 0.4 millimeter to 0.8 millimeter scope.Oil drainage hole is too little, and the time draining air is just longer, and oil drainage hole is too large, and cause seal oil mass to discharge too many, internal pressure is low, and recovery damping force is less than normal.
Further, the length that described damping spring is compressed to limit position is L, and described oil drainage hole is less than L to the distance of guide holder lower end surface.If oil drainage hole position is more than L, when damping spring is compressed to the shortest, piston can block oil drainage hole.
Further, described guide holder cylindrical is provided with the first annular groove.Annular groove on guide holder cylindrical by with the roll extrusion of damper clutch release slave cylinder after form a non-removable entirety, ensure the sealing of working cylinder.
Further, described piston body is provided with through hole, and valve seat, spring sheet, valve block, piston body are assemblied on connecting rod successively, and are connected and fixed; Described valve block offers the first damping hole.
Further, described bottom valve body upper end is provided with bottom valve sheet, bottom spring sheet and foot valve seat successively, and described foot valve seat offers through hole, and described bottom valve sheet offers the second damping hole.
Further, described piston body cylindrical is provided with the second annular groove, is provided with piston ring in described annular groove, and described piston ring adopts polyoxymethylene to make.Reduce costs, function is identical.
The present invention also provides a kind of motorcycle vibration absorber, comprises piston rod as above combination and damper clutch release slave cylinder.
As mentioned above, damper clutch release slave cylinder of the present invention, has following beneficial effect:
Due to adopt damper clutch release slave cylinder cylinder body on add oil drainage hole, so both ensure that when vibration damper works, the oil of the outside oil pocket of damper clutch release slave cylinder can enter into internal high pressure oil pocket smoothly fast, in turn ensure that recovery damping force is stabilized within the wave range of requirement.
