Abstract
The utility model relates to a rear shock absorber for a motorcycle. The rear shock absorber comprises a front pipe fork, a first shock absorbing spring, a second shock absorbing spring and a shock absorbing piston; one end of the front pipe fork is provided with an accommodating cavity, and the first shock absorbing spring, the second shock absorbing spring and the shock absorbing piston are accommodated in the accommodating cavity; the first shock absorbing spring is connected between the front pipe fork and the shock absorbing piston in a resisting way; and the second shock absorbing spring is sleeved outside the first shock absorbing spring, and the length of the second shock absorbing spring is smaller than that of the first shock absorbing spring. The rear shock absorber for the motorcycle has a simple structure, the replacement of the shock absorbing springs and the shock absorbing piston is facilitated, and the maintain cost is enabled to be low; and by arranging two shock absorbing springs, the shock absorbing property can be greatly improved, and the structure is suitable for the rear shock absorber for the motorcycle.
Description
Technical field
The utility model relates to a kind of motorcycle accessories, is specifically related to a kind of rear shock absorber of motorcycle, belongs to the bumper technical field.
Background technology
The rear shock absorber of motor bike is requisite accessory on the motor bike, and it can effectively reduce motor bike jolting when riding.And with respect to the front portion of motor bike, will jolt more in the rear portion, more needs reliable and stable to the damping performance of bumper.
The rear shock absorber of motorcycle of prior art adopts telescopic shock absorber usually, and the service life of such bumper is shorter, generally about 2 years.After the retracting cylinder surface abrasion, this bumper will be ineffective.And when changing, can only with these bumper integral replacings, so just greatly strengthen maintenance cost.
For solving the problems of the technologies described above, necessaryly provide a kind of structure improved rear shock absorber of motorcycle that has, to overcome described defective of the prior art.
The utility model content
For addressing the above problem, the purpose of this utility model is to provide a kind of simple in structure, damping performance good and maintenance cost is low rear shock absorber of motorcycle.
For achieving the above object, the technical scheme that the utility model is taked is: a kind of rear shock absorber of motorcycle, and it comprises front pipe fork, the first damping spring, the second damping spring and dashpot piston; Wherein, described front pipe is pitched an end and is provided with a host cavity, and described first, second damping spring and dashpot piston all are contained in this host cavity; Described the first damping spring is connected between front pipe fork and the dashpot piston; Described the second damping spring is set in outside the first damping spring, and its length is less than the length of the first damping spring.
Rear shock absorber of motorcycle of the present utility model further is set to: be provided with a seal ring in described dashpot piston.
Compared with prior art, the utlity model has following beneficial effect: rear shock absorber of motorcycle of the present utility model is simple in structure, and damping spring and dashpot piston are convenient to change, and make maintenance cost low; It can improve damping performance greatly by two damping springs are set, and is applicable to rear shock absorber of motorcycle.
Description of drawings
Fig. 1 is the structural representation of rear shock absorber of motorcycle of the present utility model.
The specific embodiment
See also shown in the Figure of description 1, the utility model is a kind of rear shock absorber of motorcycle, and it comprises that a few part assemblings such as front pipe fork the 1, first damping spring 2, the second damping spring 3 and dashpot piston 4 form.
Wherein, described front pipe is pitched 1 one ends and is provided with a host cavity 11, described first, second damping spring 2,3 and dashpot piston 4 be contained in this host cavity 11.
Described the first damping spring 2 is connected between front pipe fork 1 and the dashpot piston 4.Described the second damping spring 3 is set in outside the first damping spring 2, and its length is less than the length of the first damping spring 2.
Be provided with a seal ring 41 in described dashpot piston 4, thereby can effectively avoid dust to enter in the host cavity 11, avoid the unnecessary wearing and tearing of dashpot piston 4.
When jolting hour that this rear shock absorber is subject to, described the first damping spring 2 is connected to the technique effect that reaches damping on the dashpot piston 4; And when jolting of being subject to of rear shock absorber was larger, the first damping spring 2 can't absorb whole brisances, and at this moment, the second damping spring 3 and the first damping spring 2 are connected to dashpot piston 4 simultaneously, avoided the first damping spring 2 tired impaired.
The above specific embodiment only is the preferred embodiment of this creation, not in order to limiting this creation, all in this creation spirit and principle within make any modification, be equal to replacement, improvement etc., all should be included within the protection domain of this creation.
Claims (2)
1. a rear shock absorber of motorcycle is characterized in that: comprise front pipe fork, the first damping spring, the second damping spring and dashpot piston; Wherein, described front pipe is pitched an end and is provided with a host cavity, and described first, second damping spring and dashpot piston all are contained in this host cavity; Described the first damping spring is connected between front pipe fork and the dashpot piston; Described the second damping spring is set in outside the first damping spring, and its length is less than the length of the first damping spring.
