The brake device in operation engages on the driving equipment or transmission. #CMT# : #/CMT# The driving equipment comprises first and second cranks (1,2) located in a hollow shaft (3) and are coupled to each other by a bolt and nut construction. At the outer end of the cranks turned away from the hollow shaft the pedals are usually fitted. A drive chain wheel (10) is rotatably positioned by a chain wheel bearing (11) on the hollow shaft. On the first side of the chain wheel a gearwheel (15) is fitted and is firmly connected with the hollow shaft. #CMT#USE : #/CMT# As a pedal car, tricycle or bicycle. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The figure presents an exploded view of the driving equipment. 1,2 : first and second cranks 3 : hollow shaft 10 : drive chain wheel 11 : chain wheel bearing 15 : gearwheel.
