ABSTRACT:
The invention relates to a drive device having stepless torque adjustment, especially for cycles. The drive device comprises a drive shaft (13), a first adjusting disc (1) arranged coaxially with the drive shaft (13), into which first adjusting disc (1) a spiral-like cutout (3) is incorporated at least partially about the center of the first adjusting disc (1), a second coaxially arranged adjusting disc (5) into which through slots (6) are incorporated which run outwards from the center of the second adjusting disc (5), and a coaxial segmented ring (27) consisting of individual segments (28) onto the outer periphery of which segmented ring (27) can be placed an endless drive element (30). The segments (28) each have extensions (43) which engage both in the spiral-like cutout (3) and in an allocated through slot (6). One of the said adjusting discs can be driven by the drive shaft (13), whereas the other non-driven adjusting disc can be blocked by means of a blocking device (10a and 10b). When one adjusting disc is blocked and the other rotates, the diameter of the segmented ring (27) can be continuously changed, so that the torque is infinitely adjustable to the desired value.
