Abstract
In the present invention, the rotational force generated by the rolling cloud of the bicycle pedal is connected between the power generating portion and the front wheel driving portion without providing a chain, thereby rotating the front wheel, reducing the size of the rear wheel while maintaining the braking force and speed of the bicycle, Which is easy to carry and store, which facilitates driving and direction switching of the bicycle.
To this end, the present invention transmits a rotational force generated by a foot cloud of a bicycle pedal to a power generating unit adjacent to a pedal, and the power generating unit drives a front wheel by transmitting a rotational force to a front wheel driving unit by a flexible cable, And the power generating unit and the all-wheel drive unit are connected in a chainless manner, so that the driving force and the speed of the bicycle can be maintained, so that the size of the rear wheel can be reduced.
Description
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-
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.
The present invention relates to a bicycle pedal system in which a rotational force generated by a pedal crest of a bicycle pedal is connected between a power generating unit and a front wheel drive unit by means other than a chain so as to rotate a front wheel, Which is easy to carry and store, which facilitates driving and direction switching of the bicycle.
To this end, the present invention transmits a rotational force generated by a pedal crest of a bicycle pedal to a power generating portion adjacent to a pedal, and the power generating portion transmits a rotational force to a front wheel driving portion by a flexible cable to drive a front wheel, The power generating unit and the all-wheel drive unit are connected in a body-like manner, and the bicycle can keep the driving force and the speed at the same level as the conventional bicycle while reducing the size of the rear wheel, The principle of solving the problem is to make it easy.
In order to achieve the above-mentioned object, the present invention provides a driving sprocket which is connected to a bicycle pedal and is mounted on a driving hub driven by a rotating shaft, the driving sprocket being connected to the driving sprocket by a driving chain And a power generating unit including a driven sprocket mounted on a driven driven hub to be rotated and a flexible cable connected to the other driven sprocket.

In addition, the present invention is characterized in that a driving force transmitted to a power generating portion provided adjacent to a pedal is transmitted to an all-wheel drive sprocket mounted on a front wheel driven hub connected to the other end of the flexible cable and connected to the front wheel drive sprocket, A front wheel driven sprocket mounted on a front wheel rotating shaft and a front wheel driving unit including a front wheel rotating shaft connected to the front wheel driven sprocket and rotated.

The present invention is capable of reducing the size of the rear wheels while maintaining the same rotational power and speed as conventional current driven bikes, thereby facilitating the carrying and storage of bicycles. In addition, the power generating unit and the front- So that there is no risk of chain disengagement, so that the driving ability of the bicycle can be improved.
Further, the present invention has an effect that the user can easily drive and change the direction of the bicycle due to the all-wheel drive system in which the driving force is transmitted by the power generating unit adjacent to the pedal.
