ABSTRACT:
A torque transmission system for effecting a driving connection between laterally spaced driving and driven shafts. A first drive member is mounted on the driving shaft, and a second drive member is mounted on the driven shaft. Each of the drive members has substantially identical pitch diameters. An endless flexible torque transmitter operatively connects the first and second drive member. A traveling insert band circumscribes and operatively engages one of the drive members at a time, and when the traveling insert band engages one of the drive members, the insert band is located radially inwardly of the endless flexible torque transmitters. The traveling insert band has leading and trailing ends located in substantially circumferentially opposed juxtaposition when the traveling insert band operatively engages one of the drive members. A mechanism is also provided selectively to derail the leading end of the traveling insert band from that drive member operatively engaged thereby. The traveling insert band is adapted, when its leading end is derailed from one of the drive members to travel to the other of the drive members and to circumscribe and operatively engage the other drive member radially inwardly of the endless torque transmitter thereby providing a different speed ratio between said driving and driven shafts.
