Abstract
The utility model particularly relates to a rear damper and belongs to the technical field of automobile and motorcycle accessories. The rear damper comprises a damper connected with a damper oil cylinder; a damping spring is sleeved on the damper oil cylinder; one end of the damping spring is limited at the damper while the other end of the damping spring is limited at an upper joint; the upper joint is connected with one end of a piston rod of the damper oil cylinder by a nut; a bulge is fixedly arranged at the excircle side of the damper; a limiting adjusting sleeve and an adjusting nut are arranged between the bulge and the damping spring; the limiting damping sleeve is contacted with the bulge; the adjusting nut is end face contact with the damping spring. The rear damper is convenient to assemble, so that the efficiency during assembly is improved; in the long term use of the damper, the damping spring is positioned in the fatigue state, so that the elasticity is reduced and the damping effect is weakened; only the adjusting nut is needed to be screwed, the limiting adjusting sleeve is gradually separated from the adjusting nut, and the damping spring is compressed and restores the original elasticity, then the original damping effect is ensured and the use period and the service life of the damper are prolonged.
Description
Technical field
The utility model belongs to the vapour accessory technical field of rubbing, and refers in particular to a kind of rear shock absorber.
Background technique
Rear shock absorber of motorcycle can be decayed rapidly because the speed of a motor vehicle, load and various road conditions change impact and the vibrations that bring, and has greatly improved the damping performance of motorcycle, has improved to some extent adaptability, travelling comfort, stationarity and Security that motorcycle is ridden.In prior art, rear shock absorber of motorcycle comprises piston, piston rod, damping spring, connecting base and lower union joint.The cylinder seat of described piston is connected with vehicle frame, and damping spring is enclosed within outside piston and piston rod, and the bottom of piston rod is connected with connecting base, and lower union joint is fixedly installed on the bottom of connecting base, and lower union joint is connected with chain stay by pivot pin.After vibration damper is installed on motorcycle, when the inadequate or damping effect of sensation comfort level is bad, must disassemble from motorcycle, time-consuming taking a lot of work after being readjusted, is installed by vibration damper again; In addition, vibration damper is in long-term work, and the elastic force of spring can weaken, and damping effect also can variation, travelling comfort, stationarity and Security when impact is ridden.
Summary of the invention
It is adjustable and extend the rear shock absorber in life cycle and life-span that the purpose of this utility model is to provide a kind of elastic force.
The purpose of this utility model is achieved in that a kind of rear shock absorber, comprises damper, and damper connection damper oil cylinder, is arranged with damping spring on damper oil cylinder; One end of damping spring is limited in damper, and the other end is limited in upper connection; Upper connection is by one end of the piston rod of nut connection damper oil cylinder, wherein, described damper cylindrical side is fixedly installed projection, is arranged with spacing adjustment sleeve and adjusting nut between projection and damping spring, spacing adjustment sleeve contacts with projection, adjusting nut and damping spring end contact.
According to a kind of rear shock absorber of the above, wherein, described spacing adjustment sleeve and protruding contact jaw are provided with restraining groove, and spacing adjustment sleeve and adjusting nut spiral shell connect.
According to a kind of rear shock absorber of the above, wherein, described adjusting nut cylindrical side is provided with flange plate.
According to a kind of rear shock absorber of the above, wherein, described flange plate outer ring is provided with the swivelling chute of being convenient to turn uniformly, and flange plate bottom is provided with the position limit cycle that prevents damping spring lateral displacement, the end face of damping spring contacts with flange plate bottom end, and position limit cycle is in damping spring inside.
According to a kind of rear shock absorber of the above, wherein, the external diameter of described position limit cycle is less than or equal to the internal diameter of damping spring.
The utility model compared to existing technology outstanding and useful technique effect is: easy to assembly, and the efficiency while having improved assembling; Vibration damper is in long-term use, damping spring is in fatigue state, elastic force declines, damping effect weakens, and only need turn adjusting nut, and spacing adjustment sleeve departs from adjusting nut gradually, damping spring is compressed, return to original elastic force, guaranteed original damping effect, thereby extended life cycle and the life-span of vibration damper.
