Abstract
The invention relates to a motorcycle shock absorber, which comprises a damper assembly, an upper hoisting ring, a bumper block arranged on the upper part of a piston rod through an axial hole, a thick spring, a thin spring, a spacer arranged between the thick spring and the thin spring and a lower hoisting ring. The thick spring and the thin spring are enwound along the axial direction of the piston rod and the cylinder body, and are arranged between the inner ends of the upper hoisting ring and the lower hoisting ring. Compared with the prior motorcycle rear shock absorber, the invention is provided with two springs playing different roles, the rider feel comfortable when riding the motorcycle or carring load. As the external thread on the lower end of the cylinder body is flexibly connected with the internal thread on the inner end of the lower hoisting ring, dismounting, and replacement and filling of the internal damping oil of the damper are facilitated, and the optimum shock absorption effect of the damper is ensured.
Description
Technical field
The present invention relates to a kind of motorcycle vibration absorber.
Background technique
The present rear shock absorber of motorcycle that uses, owing to only use a spring, in order to satisfy various requirement, it is very thick that spring is done, and as one-man by bike the time, the resiliently deformable of spring is very little, and damping effect is bad; When two people rode same car or load-carrying, the resiliently deformable of spring was very big, and the elastic return time is very short, more than two kinds of situations all do not reach good damping effect, cyclist and feel uncomfortable by bus per capita.
Summary of the invention
The purpose of this invention is to provide a kind of good damping effect, make rear shock absorber of motorcycle simple, easy to use.
The object of the present invention is achieved like this, and this vibration damper comprises damper assembly, upper rings, forms at buffer stopper, bulky spring and the spacer between bulky spring and hairspring, hairspring and the lower lift ring on piston rod top by axial bore.The damper assembly comprises piston rod, be connected in parts that are positioned at cylinder body and cylinder body on the piston rod, fixedly connected with the upper rings inner end in the piston rod upper end, piston-rod lower end is positioned at cylinder body, be connected in parts that are positioned at cylinder body on the piston rod from outside to inside being respectively retainer ring, outside framework oil seal, guider, buffer spring, valve seat, the tower spring, flow-stopping sheet, piston, piston-rod lower end portion is fixed in above-mentioned parts on the piston rod near the plain cushion and the nut of piston, fixedly connected with the lower lift ring inner end in the cylinder body underpart, between last lower lift ring the inner, the thickness spring is isolated by spacer according to the axial winding of piston rod and cylinder body for bulky spring and hairspring.
Further, be connected with the internal thread of lower lift ring inner end inboard by the outside thread that is positioned at the cylinder body underpart.
Further, the screw thread of cylinder body underpart except that in its end with the internal thread of lower lift ring inner end inboard connects, seat and locknut are adjusted by also being connected with on the screw thread of lining in end, cylinder body underpart.
Further, the thickness spring can be divided into three with spacer, even more.
Subtract device behind the present invention and the existing motorcycle and compare owing to there are two to play not same-action with upper spring, by bike all feel very comfortable during single or load-carrying; Adjust seat and locknut because the screw thread of cylinder body underpart also is connected with, can tighten spring, increase carrying capacity or when road was uneven, it is comfortable equally that the cyclist feels; Because cylinder body underpart outside thread is connected with the internal thread of lower lift ring inner end, for flexibly connecting, easy disassembly makes things convenient for the replacing and the filling of damper internal damping oil, guarantees the best damping effect of damper.
