Title:
BICYCLE DRIVING DEVICE HAVING INCREASED TORQUE
Document Type and Number:
WIPO Patent Application WO/2019/164158
Kind Code:
A1
Abstract:
The present invention relates to a bicycle driving device having increased torque, the device moving, to the front thereof, the center of a rotational track in a state in which an overall pedaling track (distance) does not increase, thereby removing the top dead center and enabling force to be strongly transmitted to a crankshaft during pedaling. According to the present invention, a rotational track of a pedal is moved to the front thereof such that when the pedal is in a forward position, the pedal is separated far away from the crankshaft so as to enable a strong force to be transmitted to the crankshaft by using the principle of the lever, and thus rotational torque can be increased.
