摘要

#CMT# #/CMT# A tubular coupling piece (5) is mounted on the pedal axle (2) and can rotate around it relative to the mounting section of this axle. The coupling piece has primary and secondary coupling ends located in the region of the left end of the axle and the drive section of the axle respectively. A chain wheel is mounted on the primary coupling end and can be rotated around the pedal axle with the coupling piece. A wheel unit is rotatably mounted in the bicycle frame and is connected to and driven by the chain wheel. Two gear-wheels (41, 44) in a transmission are connected to the drive section of the pedal axle and to the secondary coupling end in order to transmit the increased angular velocity of the last gear-wheel to the coupling piece so that the chain wheel is rotated. #CMT# : #/CMT# The mounting and drive sections of the pedal axle are located in an intermediate part of the axle between its left and right ends and are located opposite each other in the axle length direction. A pair of pedal arms are secured to the ends of the pedal axle and each one is connected to a pedal. #CMT#USE : #/CMT# A bicycle is described. #CMT#ADVANTAGE : #/CMT# A smaller chain wheel can be used. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The figure shows a partial cross-section of the pedal axle and gear transmission. 2 : pedal axle 5 : tubular coupling piece 41, 44 : gear-wheel.
