Abstract
The utility model relates to a damping front fork for motor-assisted bicycles or bicycles, which is composed of an outer cylinder 2, a damping spring installed in the outer cylinder and a piston rod inserted in the outer cylinder 2. When the front fork is arranged on the bicycles, the vibration force generated by a front wheel in the running process can be absorbed by the damping spring, and thus, the vibration force transmitted to a handle bar is relatively small so that a rider feels comfortable.
Description
The utility model belongs to a kind of bicycle front fork.
The boosted vehicle of selling in the market and using, its front fork of bicycle do not have shock-absorbing function and can not give the cyclist with comfort.
The purpose of this utility model is that a kind of boosted vehicle, front suspension fork of bicycle will be provided, and after boosted vehicle, bicycle adopt this shock-absorbing front fork, good damping effect is arranged, and makes the cyclist that better comfort be arranged.
For reaching above-mentioned purpose, the utility model has adopted knockdown front fork, and the piston rod that promptly has urceolus and skewer to go in it constitutes, damping spring also is housed in tube, piston is housed on piston rod, an end of urceolus is connected with the front truck wheel shaft, the piston rod connection pipe is connected with handlebar and gets final product.Bicycle shaking force under steam can be absorbed by damping spring, plays cushioning effect, the utility model has the advantages that simple in structure, good damping effect.
Below in conjunction with the embodiment of description of drawings the utility model on bicycle.
Fig. 1 wherein 9 is front suspension fork of bicycle for this shock-absorbing front fork is installed in situation on the bicycle.
Fig. 2 is the amplification semisectional view of this shock-absorbing front fork, and wherein 2 is urceolus, and damping spring 3 is installed in the urceolus 2, and two end caps of damping spring 3 are equipped with locating bush 1.Piston rod 5 skewers are contained in the urceolus 2, and its top is equipped with piston 4.6 and 7 are respectively seal ring and back-up ring, and seal ring 6 lids are contained on the urceolus 2, and back-up ring 7 is inlaid between seal ring 6 and the urceolus 2 and plays fixed seal ring 6.The back central authorities of piston rod 5 are welded with connection pipe 8, screw thread are arranged in order to be connected with cycle frame on it.
The connection pipe 8 of this bumper front fork by piston rod 5 is installed on the cycle frame, and an end of urceolus 2 is connected with front wheel spindle and gets final product.Under steam, the shaking force that is transmitted by front-wheel passes to damping spring 3 through urceolus 2, makes damping spring 3 be subjected to force compresses, and so most of shaking force is just absorbed by the distortion of damping spring 3, the shaking force that reaches handlebar through piston 4 and piston rod 5 is just very little, and the cyclist just has good comfort.
Claims (1)
- A kind of boosted vehicle, front suspension fork of bicycle is characterized in that by urceolus 2 and are installed in damping spring 3 wherein and skewer dress top within it is equipped with the piston rod 5 of piston 4 and the connection pipe 8 that is welded on the piston rod 5 is formed.
