Description

Motorcycle vibration absorber

Technical field

The utility model relates to vibration damper, particularly a kind of motorcycle vibration absorber.

Background technique

Existing motorcycle vibration absorber is a spring-loaded load-carrying, a push rod is arranged in the middle of the spring, because the push rod bar is far away from the spring inside diameter back gauge, spring center is difficult for fixedly being easy to generate beat when the driving of carrying weight, cause easy-rupturing, and a spring load-bearing is easy to generate fatigue, the spring easy-rupturing.

Summary of the invention

The purpose of this utility model is to provide a kind of spring to divide inner spring, outer spring, and divide epimere, hypomere spring, and the tab-delimited circle of spacing pad is arranged in the middle of the spring, and is reasonable in design, easy to manufacture, easy to install, the motorcycle vibration absorber of spring long service life.

Technical solution of the present utility model is such, comprise by upper support circle, lower support circle, stop bit pad, carrying cylinder bar, movable push rod, seal ring, up and down in outer spring, shock absorber body.Epimere has inside and outside spring in the shock absorber body inner chamber, and hypomere has inside and outside spring, is separated with up and down spring seat between the supreme inside and outside spring of following inside and outside spring mutually and isolates the supporting of being separated by of positioning ring, leather cup.There is movable push rod therefrom to pass in heart hole in the middle of positioning ring, the leather cup supporting.The underpart of shock absorber body and sleeve upper end portion have piston ring to make sealing usefulness.The bottom of the last inside and outside spring in the motorcycle damping device cavity is bearing on the seat surface of lower spring cup.Be sleeve under the lower spring cup, the stop bit pad is an intracavity bottom at the carrying cylinder bar, and the caping end is the upper support circle, and the bottom is the lower support circle, and leather cup supporting bottom end is pressed on the end face of sealing gasket.Sealing gasket is contained in the upper end counterbore of carrying cylinder bar, and in the inner chamber of outer spring, the beneath end of movable pull rod was equipped with the stop bit pad in movable push rod passed up and down, and the stop bit pad is in the inner chamber bottom of carrying cylinder bar.Carrying cylinder bar bottom is the lower support circle.There is the upper support circle in the central lumen and the hole of movable push rod outer spring, positioning ring, leather cup supporting, carrying cylinder bar in up and down above the loam cake.

The utility model has the advantages that reasonable in designly, easy to manufacture, easy to install, safe and reliable, practical, the spring long service life is suitable for using on the motorcycle.

Description of drawings

It is such that structure of the present utility model constitutes:

Fig. 1 looks sectional view for overall structure master of the present utility model.

Fig. 2 is an overall structure side-looking partial sectional view of the present utility model.

Among Fig. 1-Fig. 2.Upper support circle (1), stop bit pad (2), pin (3), carrying cylinder bar (4), backbone sealing ring (5), sleeve (6), piston ring (7,8), lower spring cup (9), following inner spring (10), following outer spring (11), last outer spring (12), shock absorber body (13), spring pad (14), lid (15), upper support circle (16), nut (17), last inner spring (18), spring seat is isolated positioning ring (19), leather cup rim (20), sealing gasket (21), O RunddichtringO (22), piston ring (23,24), piston mandril (25), spring force Adjusting ring (26), positioning block (27), pin (28).

Embodiment

Most preferred embodiment of the present utility model is such.Referring to figs. 1 through Fig. 2, this vibration damper is to become the segmented spring with reference to existing Monolithic spring structural reform, separates with positioning ring in the spring joint.Spring increases the internal layer spring.Like this, use the internal layer spring can reach the carrying effect when underloading, outer spring also together works during loads, uses safely when reaching heavy loading object.Piston ring groove and ring installation (7,8,23,24) are arranged between sleeve (6) upper end-hole external diameter and shock absorber body (13) bottom diameter, the last lower spring that shock absorber body (13) internal diameter has segmentation to work alone, epimere outer spring (12) wherein, be inserted in inner spring (18) in the internal diameter, can relatively independent activity between it about.Following outer spring (11) internal diameter in like manner has been inserted in down inner spring (10), can be relatively independent up and down between it.In the endoporus of inner spring (10,18) movable push rod (25) being housed passes from the center.There are last lower spring cup positioning ring (19), leather cup supporting (20) to be separated by and to tell the hypomere spring between the interior up and down outer spring, outer spring (18,12) bottom surface is in positioning ring (19) top in going up, the end face of outer spring is positioning ring (19) in going up, leather cup supporting (20) end face is close to the bottom surface of positioning ring (19), and the external diameter of supporting (20) is enclosed within down in inner spring (10) internal diameter.Positioning ring (19) is supporting interior outer spring (18,12).Movable push rod (25) passes from positioning ring (19), leather cup supporting (20) center hole, and leather cup supporting (20) bottom is close to and is pressed in seal ring (21) end face, and seal ring (21) is contained in the counterbore of carrying cylinder bar (4) top.Movable push rod (25) also passes from seal ring (21) center hole.The end face roof pressure of going up outer inner spring (12,18) has spring pad (14) and lid (15).On the lid (15) is bearing ring (16).Stop bit pad (2) is equipped with in movable push rod (25) bottom, by connecting with pin (3).Along with covering (15) up and down, there is the counterbore screw in lid (15) bottom centre to stop bit pad (2) in carrying cylinder bar (4) endoporus, and push rod (25) is twisted to screw in and connected.Other parts structure characteristic of this vibration damper and manufacturing, install and use with reference to the manufacturing of existing conventional vibration damper and install and use.

Of the present utility model installing and using is that the tail stool replaced existing vibration damper after bearing ring (16,1) was installed in motorcycle by the prior art installation method up and down.Under car underloading situation, use earlier the inner spring load-bearing, during vehicle-mounted overweight situation then outer spring work, and spring-leaf retainer up and down in the middle of the movable push rod and shock absorber body can keep spring to open that the position keeps Vertical direction to be difficult for beat when stretching, the folding power wearing and tearing when taking in sail, and spring is easy-rupturing not then.The moving equilibrium safety that keeps car.
