Abstract
The utility model belongs to the technical field of motorcycle accessories and particularly relates to a rear shock absorber with two springs. The rear shock absorber comprises a cylinder body and a piston rod, the outer end of the piston rod is connected with an upper connector, and a lower connector is arranged at the outer end of the cylinder body, wherein the two springs are arranged between the cylinder body and the piston rod, the cylinder body and the piston rod are arranged between the upper connector and the lower connector, the rectangular spring with rectangular cross section is arranged on the cylinder body, and the cylindrical spring with circular cross section is arranged on the piston rod. The rear shock absorber enables damping springs to be increased from one to two, leads spring stiffness curves be changed into a three-section type from a traditional two-section type, meets damping requirements during normal running, and simultaneously can increase load bearing capacity.
Description
Technical field
The utility model belongs to the motorcycle accessories technical field, refers in particular to a kind of double-spring rear shock absorber.
Background technique
At present, when the vibration damper of single spring of available technology adopting, single rider, use first rigidity of damping spring can satisfy shock attenuation needs; When two people ride, then need to use second rigidity of damping spring 10 just can meet the demands; But, motorcycle in use needs loading sometimes, or sometimes need to ride more than two people, the ability of the bearing load of the vibration damper of single spring of use is subjected to the limitation of single spring, so it is permanent tired to use high performance material to satisfy, and will cause cost of production to increase like this.
Summary of the invention
The purpose of this utility model provides a kind of double-spring rear shock absorber that strengthens vibration damper bearing load ability.
The purpose of this utility model is achieved in that double-spring rear shock absorber, comprise cylinder body and piston rod, the outer end of described piston rod connects upper connection, the cylinder body outer end is provided with lower contact, wherein, be provided with two springs between cylinder body between upper connection and the lower contact and the piston rod, on the cylinder body is that cross section is the rectangle spring of rectangle, and on the piston rod is that cross section is circular cylindrical spring.
According to the double-spring rear shock absorber of the above, wherein, described rectangle spring and cylindrical spring adopt the mode of series connection to form.
According to the double-spring rear shock absorber of the above, wherein, be provided be used to the setting sleeve that separates two springs between described rectangle spring and the cylindrical spring, setting sleeve can be subjected to load to-and-fro motion campaign with rectangle spring and cylindrical spring.
According to the double-spring rear shock absorber of the above, wherein, described setting sleeve adopts light aluminum alloy material to make.
According to the double-spring rear shock absorber of the above, wherein, described piston rod and upper connection joint are provided with cushion plugs.
The utility model outstanding and beneficial technical effects compared to existing technology is:
1, the utility model changes damping spring into two by one, makes the spring rate curve become 3 stops by traditional two section type, not only satisfies the shock-absorbing when normally travelling, and can also increase the ability of bearing load simultaneously.
2, the utility model does not need to change the effective travel of rear shock absorber, and the comfort property of riding motorcycle is demonstrated fully.
3, the utility model has avoided the employing high performance material to satisfy permanent fatigue, has saved cost of production.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Among the figure: 10-cylinder body, 11-piston rod, 12-lower contact, 13-upper connection, 14-rectangle spring, 15-cylindrical spring, 16-setting sleeve, 17-cushion plugs.
Embodiment
The utility model is further described with specific embodiment below in conjunction with accompanying drawing, referring to Fig. 1: double-spring rear shock absorber, comprise cylinder body 10 and piston rod 11, the outer end of described piston rod 11 connects upper connection 13, cylinder body 10 outer ends are provided with lower contact 12, wherein, are provided with two springs between the cylinder body 10 between upper connection 13 and the lower contact 12 and the piston rod 11, on the cylinder body 10 is that cross section is the rectangle spring 14 of rectangle, and on the piston rod 11 is that cross section is circular cylindrical spring 15.
According to the double-spring rear shock absorber of the above, wherein, described rectangle spring 14 and cylindrical spring 15 adopt the mode of series connection to form.
According to the double-spring rear shock absorber of the above, wherein, be provided with between described rectangle spring 14 and the cylindrical spring 15 be used to the setting sleeve 16 that separates two springs, setting sleeve 16 can be subjected to load to-and-fro motion campaign with rectangle spring 14 and cylindrical spring 15.
According to the double-spring rear shock absorber of the above, wherein, described setting sleeve 16 adopts light aluminum alloy material to make.
According to the double-spring rear shock absorber of the above, wherein, described piston rod 11 is provided with cushion plugs 17 with upper connection 13 joints.
The double-spring rear shock absorber that the utility model provides, in use, when single rider, because the load of motorcycle is lighter, 15 main carrying cushioning effects of cylindrical spring, 14 less important carrying cushioning effects of rectangle spring, when riding jointly more than two people, because the load of motorcycle increases the weight of, piston rod 11 continues to move downward and extended stroke, this moment, rectangle spring 14 and cylindrical spring 15 played the carrying cushioning effect simultaneously, had overcome the narrow limitation of single spring damper bearing load in the background technique, had strengthened the damping performance of vibration damper greatly; In order to prevent that piston rod 11 over-travel from causing bumping between upper connection 13 and the cylinder body 10, so piston rod 11 is provided with cushion plugs 17 with upper connection 13 joints; And the utility model do not need to change the effective travel of rear shock absorber, and the comfort property of riding motorcycle is demonstrated fully.
Above-described embodiment is preferred embodiment of the present utility model only, is not to limit protection domain of the present utility model according to this, so: all equivalences of doing according to structure of the present utility model, shape, principle change, and all should be covered by within the protection domain of the present utility model.
