Description

A kind of damping type bicycle rack

The utility model relates to a kind of damping type bicycle rack.

Bicycle is in the modern society of prosperity, and by the original function divertical motion leisure trend gradually of riding instead of walk, but the characteristic of pollution-free, light because of it again and body-building makes its personal short distance traffic instrument in a kind of excellent city of also can yet be regarded as.The structure of bicycle and quality are along with the improve of living standards of the people, also aspect the traveling comfort that drives significant progress is being arranged, wherein topmost variation, be that promptly vehicle frame changes the damping type structure into by original pure rigid construction, winnow with a dustpan top of being born between advancing with the reduction person of riding and shake, the damping type vehicle frame of generally commonly using, its bumper all is located at before the front and back wheel place on the fork and back vent, wherein hold on two front fork tubes front fork bumper system position, the back vent bumper then is located at two arm upper ends of vehicle frame, i.e. general as shown in Figure 1 position, right this kind design is not the suffered vibrations of the direct absorption person of riding itself, and be to absorb the vibrations that wheel conducts to vehicle frame, for the person of riding, the shock-absorbing effect of bumper is indirect person, but not direct bench hassock tube generation shock-absorbing effect to the carrying person of riding weight, the back vent bumper tends in climbing during the road surface again, because of the flexible strength that will the person of riding stepped on of bumper partly siphons away.Right its disadvantage is also not only in this; when travelling on the road surface of jolting; when desire uses change-speed box to step on power with adjustment; chain takes place in regular meeting jumps the tooth situation; moreover bumper is installed on the arm, must be symmetrical arranged; each bumper promptly, no matter cost of parts and assembly cost are all higher.

The purpose of the utility model is to improve the shortcoming of prior art and provides a kind of and bumper is installed between two pipes that are divided into two, the vibrations that make bumper directly absorb the person of riding to be born, promptly do not ride the person and be equivalent to directly take on bumper, to improve damping effect greatly.

Another purpose of the present utility model is only must use a bumper, can reduce cost of parts and built-up time effectively like this, increases substantially production efficiency.

The purpose of this utility model be achieved in that vehicle frame system by the seat pipe, go up pipe, pipe, seat pipe support, seat arm, bumper, shape permanent seat, five-way pipe, head tube etc. are formed down.Wherein a seat pipe is divided into seat of honour pipe, following and manages two sections, the five-way pipe of the lower end connection axis of a described following pipe, the upper end connects two seat arms and a mounting pipe, and the other end of this mounting pipe is fixed in down pipe, and fixes a shape permanent seat at the upper surface of mounting pipe; Described seat of honour pipe and the affixed across of last pipe, the other end of last pipe is articulated in head tube or manages, and can rotate up and down around drive-connecting shaft down; Also fix a shape permanent seat with the cooresponding lower surface of going up pipe of the shape permanent seat on the following pipe, a bumper is housed between two shape permanent seats.At last pipe or the position, hole of or more than one fixedly bumper is arranged on the shape permanent seat of pipe down, bumper is installed in different positions, hole, make bumper be different heeling conditions, with the elasticity at the levelling person of riding seat.

The utility model good damping effect, designs simplification, economical with materials and built-up time.
