Abstract

The utility model relates to an adjustable double-spring hydraulic type rear shock absorber for motorcycles, which belongs to the technical field of the class of components and parts of motorcycles. When a motorcycle is used, one rider (light load), or two or three riders (heavy load) are carried by the motorcycle, therefore the rear shock absorber needs to have a big enough strength to moderate shock and support the motorcycle body, however, a problem that when a person rides the motorcycle the rear shock absorber with large strength is hard and has poor riding comfort is brought, which is the defect of the traditional rear shock absorber. The adjustable double-spring hydraulic type rear shock absorber for motorcycles has the essential structure that compared with the traditional rear shock absorber, the utility model is additionally provided with main parts comprising an inner spring, an adjusting sleeve, a big positioning block, a support ring, shaped locking nuts; the distribution of the exerted force of the spring is changed through the upward and the downward motion of the adjusting sleeve to adjust the strength of the shock absorber (when the motorcycle is provided with heavy load, the upmost position of the adjusting sleeve fully makes contact with the lower end of the inner spring, and the inner spring and an outer spring are together exerted by force, at the moment, the strength of the shock absorber is increased; when the motorcycle is provided with light load, the adjusting sleeve is adjusted to the lowest position which does not make contact with the inner spring, only the outer spring is exerted by force, and at the moment, the strength of the shock absorber is the smallest), so that the hardness of the rear shock absorber can be ensured to be matched with the motorcycle where under light load or heavy load and the riding comfort and the safety of riders when riders ride the motorcycle are largely enhanced.

Description

Adjustable double spring hydraulic type rear shock absorber of motorcycle
Technical field
The utility model relates to a kind of rear shock absorber of motorcycle.
Background technique
Existing rear shock absorber of motorcycle all is to adopt single damping spring, when carrying capacity not simultaneously damping effect differ greatly, cause driving uncomfortable, feel too soft during the too hard and heavy duty of sensation vibration damper during underloading in actual use.
Summary of the invention
Technical problem to be solved in the utility model is: a kind of vibration damper is provided, and this vibration damper makes the weight that vibration damper carries and the soft or hard degree of vibration damper reach harmonious unification by the distribution that changes spring stress, allows more safety and comfortable of driving.
Technical problem to be solved in the utility model is by adopting such technological scheme to realize, it is a kind of adjustable double spring hydraulic type rear shock absorber of motorcycle, its main points are: special-shaped locking nut is positioned at the upper connection below and locks mutually by the screw thread and the upper connection of piston rod, the top of inner spring and special-shaped locking nut lower end are fixedly linked, the top of adjustment sleeve and inner spring bottom be adjustable range as required, the semicircle breach classification in the lower end of adjustment sleeve contacts with little positioning block, and the outer spring bottom contacts with the support ring top.Support ring is interior to be to rock to prevent outer spring for being enclosed within the outer spring bottom inside along the circle that projection is arranged.The bottom of support ring contacts with big positioning block top, and big positioning block is positioned at the damper below, and bilateral symmetry is fixed respectively, and is 90 ° of angles with little limiting stopper.The top of abnormity locking nut is square or hexagonal configuration, so that open-end wrench is locked it.In use, when motorcycle has only an occupant, adjustment sleeve upper semi-circle v notch v contacts with little positioning block, Transverse plane and adjustment sleeve maintain bigger distance under the inner spring at this moment, what bear pressure is outer spring, having only under the separately stressed situation of outer spring the rear shock absorber bulk strength softer, travelling comfort is splendid like this; When motorcycle is when heavy duty (be three occupants on the car or carry cargo), available hand is mentioned adjustment sleeve and is rotated to an angle left, this moment, the lower semi-circular breach of adjustment sleeve contacted with little limiting stopper, Transverse plane and adjustment sleeve upper end plane contact under the inner spring, interior outer spring is stressed jointly, can guarantee that like this rear shock absorber has enough intensity to relax vibratory impulse, allow driving more safely with comfortable.In addition, adjustable double spring hydraulic type rear shock absorber of motorcycle also can use for bicycle, electric motor car, motor tricycle, automobile by the suitable adjustment on the size.
The beneficial effects of the utility model are: can significantly improve the travelling comfort of occupant when driving motorcycle, also take into account Security simultaneously.The damper structure of this product can keep identical with existing mill run, need not do any change, can be beneficial to reduce production costs, and improves reliability of products.
