Technical field
The present invention relates to a kind of manpower bicycle more particularly to a kind of four-wheeled bicycles of controllable vehicle backward.
Background technique
The vehicles play weight effect in the national economic development, it is well known that advance for outdoor activity, short distance
Deng ordinary bicycle on a tubular type vehicle frame is housed, a vehicle seat and a handlebar are had on vehicle frame.On this bicycle,
Front and back wheel is on the crotch of vehicle frame rear and front end and rotatable by axis and bearing respectively.A list is also equipped on vehicle frame
To driving device, which includes two sprocket wheels: the drive sprocket of major diameter and the pawl chain of a minor diameter.It drives
There is an axis on movable sprocket, there are two pedal, which is mounted in a stationary bushing on vehicle frame simultaneously dress at the both ends of the axis
It is rotatable.Pawl sprocket wheel is support positioned at rear-wheel center by vehicle frame and is connected to drive sprocket by a ring chain.Spine
An one ratchet mechanism i.e. one-way clutch is housed on dog chain wheel, the power that rotates in the forward direction of drive sprocket is transmitted to hind axle
On.That is, user can be sitting on vehicle seat and with the hands hold handlebar, then pedal is stepped on to rotate in the forward direction drive chain
The power that rotates in the forward direction on drive sprocket, can be transmitted on pawl sprocket wheel, and be therefore transmitted on rear-wheel by wheel by chain, thus
Rotation rear-wheel simultaneously makes bicycle advance on the ground.However, when drive sprocket reversely rotates, the one-way clutch of pawl sprocket wheel
Reverse rotational force on drive sprocket will not be transmitted on rear-wheel, pawl link can only dally, without can be carried out backward.It is this
In the case of, bicycle can move on a period of time under the action of inertia force.With the development and diversification of people's lives
Demand, popularizing for miniature four-wheel vehicle will also become a part of human needs.The traveling of miniature four-wheel vehicle is from driving functions
On also needed car-backing function, flexible u-turn turning function can just be had by driving to get up in this way, but for the bicycle of four-wheel
For, it because of its turning and moves backward very inconvenient, and can only move ahead and move backward relatively difficult, be always puzzlement numerous people and section
Grind a great problem of personnel.
