Abstract
Description
BACKGROUND OF THE
Generally, bicycle refers to a vehicle that moves by turning the wheels by stepping on the pedals with two legs.
However, the conventional bicycle has a problem that the chain is peeled off or oil is painted on the chain, so that the body part, the pants are dirty, and the skirt is curled, thereby causing trouble and safety accident.
Korean Utility Model Registration Utility Model No. 20-0306417 discloses a shaft drive of a body recognition bicycle.
However, such a bicycle has a problem that it is not easy to transmit power when the bicycle is turned in a narrow space, a curved section, or the like.
SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide a power transmission device for a bicycle which is capable of easily transmitting power even in a narrow space, Shaft, a power transmission device, and a motorcycle equipped with the same.
The problems to be solved by the present invention are not limited to those mentioned above, and other solutions not mentioned can be clearly understood by those skilled in the art from the following description.
In order to achieve the above-mentioned object, the present invention includes a driving shaft which is provided on a single-body bicycle having front and rear wheels and a pedal, and both ends of the front and rear wheels and the pedal are engaged with the rear wheel and the pedal Wherein the drive shaft is made flexible in such a manner that a winding member made of a metal is wound in a spiral shape. The shaft for a power transmission device according to any one of
The apparatus further includes a casing coupled to the outside of the drive shaft.
Further, the present invention is further characterized by a reinforcing bar provided inside the drive shaft.
The apparatus may further include a bending prevention cover detachably coupled to an outer side of the casing or the driving shaft to prevent the driving shaft from being bent.
The bending prevention cover according to the present invention is characterized in that both ends of the bending prevention cover are open and one side is opened and a detachment hole is detachably attached to the outside of the driving shaft, and a single or a plurality of magnets are provided inside.
There is provided a power transmission apparatus for a bicycle comprising a shaft for a power transmission device of a bicycle according to the present invention.
There is provided a bicycle comprising a power transmitting device of a bicycle according to the present invention.
According to the present invention, there is an effect that power transmission can be easily performed even when a direction is changed in a narrow space, a curved section, or the like.
In addition, when the vehicle is running straight, the drive shaft can be prevented from bending and smooth running can be achieved.
The effects of the present invention are not limited to those mentioned above, and other solutions not mentioned may be clearly understood by those skilled in the art from the following description.
FIG. 1 is a perspective view showing a conventional bicycle with a shaft for a power transmission apparatus of a bicycle according to the present invention.
Fig. 2 and Fig. 3 are longitudinal sectional views showing a shaft for a power transmitting apparatus of a bicycle according to the present invention.
4 is an exploded view of a bending protection cover in a shaft for a power transmission apparatus of a bicycle according to the present invention, in accordance with the present invention.
5 and 6 are a perspective view and a side view showing a bending prevention cover in a shaft for a power transmission apparatus of a bicycle according to the present invention, according to the present invention.
Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
