Abstract

The purpose of the present invention is to provide a chainless front-wheel driving bicycle easy to keep and carry capable of rotating a front wheel by connecting torque generated when pedaling on the bicycle without installing a chain between a power generating unit and a front wheel driving unit, reducing the size of a rear wheel while maintaining the thrust and speed of the bicycle, and facilitating the movement of the bicycle and directional change. To achieve this, the present invention is capable of transmitting the torque generated by pedaling on the bicycle to the power generating unit which is adjacent to a pedal. The power generating unit transmits the torque to the front wheel driving unit via a flexible means to drive the front wheel and rotates the rear wheel by driving the front wheel. The power generating unit and the front-wheel driving unit are connected in a chainless method, and thus the driving force and speed of the bicycle are maintained. Accordingly, the size of the rear wheel can be remarkably reduced.

Description

[0001] The present invention relates to a bicycle, a bicycle,

The present invention relates to an all-wheel drive bicycle which is easy to carry and store. More particularly, the present invention relates to an all-wheel drive bicycle, Driven bicycle without a chain in which the rear wheels are driven by driving the front wheels.

Generally, a bicycle has an all-wheel drive system in which front wheels are rotated by a pedal crest, a rear-wheel drive system in which a rear wheel is rotated, and a two-wheel drive system in which front and rear wheels are simultaneously rotated.

FIG. 1 is a perspective view of a conventional high-wheel bicycle, and FIG. 2 is a perspective view of a conventional recumbent bicycle. In the conventional all-wheel drive bicycle, a pedal is connected to a front wheel rotation shaft without a chain drive device, There is a recumbent bicycle that rotates the front wheel by attaching the chain driving device to the front wheel and connecting the pedal to the front wheel rotation axis.

However, the high-wheel bicycle having a pedal on the front wheel has a small rear wheel, which is high in portability. However, since there is no driving device such as a chain, there is a limit to increase the speed, and a recumbent bicycle equipped with a chain driving device on the front wheel, The bicycle operation may be unstable when driving and turning directions at the same time.

As the population increasingly uses bicycles for leisure and sports purposes, there is an increasing need for bicycles that are portable and easy to store. For this purpose, attempts have been made to reduce the size of bicycles. However, The conventional rear wheel drive bicycle has a limitation in reducing the size of the bicycle because the speed of the rear wheel is reduced.

FIG. 3 is a perspective view of a conventional two-wheel drive bicycle. The conventional two-wheel drive bicycle 300 is for rotating the front wheel and the rear wheel simultaneously to increase the braking force of the bicycle. And the power transmission unit 310 transmits rotation force to the rear wheel drive unit 330 by the chain 325 to rotate the rear wheel 360. The power transmission unit 310 is a flexible And transmits the rotational force to the front wheel drive unit 350 by the cable 340 to rotate the front wheel 370.

However, the two-wheel drive bicycle which rotates the front wheel and the rear wheel at the same time is mainly driven by the rear wheel drive, and the all-wheel drive is assisted by this to increase the driving power. The power generating portion and the rear wheel drive portion are connected by a chain. The size of the bicycle can not be reduced, so that it is not easy to carry and store the bicycle.
