Abstract

The utility model relates to a bicycle which can effectively reduce the vibration, and a front fork part and a back wheel inclined fork part of the existing bicycle are replaced by a group of vibration absorbers with a spring structure. The upper and the lower ends of a back vibration absorber are connected with a frame and a back flat fork by universal joints, the back flat fork is connected with an outer casing of a middle shaft by a bearing, so, the vibration transferred by a front and a back wheels can be effectively absorbed by the acting force of a spring.

Description

Damping bicycle

The utility model relates to a kind of bicycle that can effectively reduce the vibrations that cause owing to Uneven road when driving car.

At present, except that tire, vehicle seat had certain shock-absorbing function, no any device that can effectively reduce vibrations brought discomfort for the rider when Uneven road in the existing bicycle structure.

The purpose of this utility model provides a kind of bicycle, and it not only has the function of existing bicycle, and can reduce the vibrations of upwards transmitting from front and rear wheel effectively.

The purpose of this utility model is achieved in that the bumper of two spring structures of parallel installation in the front fork position, to absorb the vibrations of upwards being transmitted by front-wheel.Put the bumper that is two spring structures of acute angle triangular form installation in the vent of retreading, to absorb the vibrations of upwards transmitting by trailing wheel.Rear wheel shock-absorbing device upper and lower end respectively designs a universal-joint, makes the shift in position of time spent to adapt to the rear wheel shock-absorbing device.Back chain stay becomes rigidity with being connected of vehicle frame and flexibly connects into bearing-type.

Owing to adopt such scheme, bicycle can reduce the vibrations by the front and rear wheel transmission effectively, drives comfortable.And external form is simple in structure near existing bicycle.

Below in conjunction with accompanying drawing the utility model is further specified.
