Abstract

The utility model relates to a shockproof bicycle which comprises a front wheel (8), a frame, a saddle (1) and a back wheel (16). The utility model is characterized in that the front end of a cross beam (3) of the frame is rotationally connected with the front end of an oblique beam (4), and the front end of the oblique beam (4) is rotationally connected with a front fork (9) in the horizontal direction. The front part of a bracket of the back wheel is rotationally connected with the back end of the oblique beam (4), and the lower part of the cross beam (3) is connected with a connecting support (10) through a back damping spring (2). The bracket of the back wheel is connected with the connecting support (10) through a transverse shock damper (12). The utility model has better shockproof effect.

Description

Shockproof bicycle

The utility model relates to a kind of bicycle.

In the prior art, bicycle generally is made up of spider, front-wheel, trailing wheel, vehicle seat, front fork etc., and shock absorbing apparatus generally is positioned over the below of vehicle seat, and whole spider is a rigid structure, so shock-proof effect is bad.

The purpose of this utility model is to provide a kind of shockproof bicycle with better shock-proof effect.

The technical solution of the utility model is: a kind of shockproof bicycle, comprise the front-wheel that is arranged on the front fork, be arranged at the handle of the top of front fork, vehicle frame, vehicle seat, be arranged at the trailing wheel on the rear wheel support, the front end of the crossbeam in the described vehicle frame and the front end of cant beam vertically are rotatably connected, the front end of described cant beam and front fork horizontal direction are rotatably connected, the front portion of described rear wheel support and the rearward end of cant beam vertically are rotatably connected, on the described crossbeam vehicle seat is housed, the below of described crossbeam be fixed in cant beam on link span between by the back damping spring be connected, another place of described rear wheel support also with between the described link span is connected by transverse damper.

The utility model compared with prior art has following advantage:

Because crossbeam and cant beam are rotatably connected, so vehicle seat can be that the center of circle has the bigger amplitude that swings up and down with its run-on point, and its swing slows down impulsive force by back damper spring, so this car has damping effect longitudinally; Front-wheel slows down its longitudinal impact force by preceding damper spring, and trailing wheel since rear wheel support and being rotatably connected of cant beam and can its to be rotatably connected a little be that swing in the center of circle, and its swing is subjected to slowing down of transverse damper and has reduced impulsive force, therefore but this car changes rigidity spider in the past into damping moving vehicle frame, has tangible shock-proof effect.

The utility model will be further described below in conjunction with drawings and Examples:

Accompanying drawing is a structural front view of the present utility model; Wherein:
