Abstract: The present disclosure relates to an eccentric gearing having a first gearing element, which has a first axis and an outer contour having at least one cam, and having a second gearing element, which has a second axis which is constantly held eccentrically in relation to the first axis. The first gearing element is rotatable relative to the second gearing element, and the second gearing element is supported on the outer contour of the first gearing element such that a rotation of the first gearing element effects a rotation of the second axis of the second gearing element about the first axis. The first gearing element has a number N of cams protruding radially, and uniformly distributed in the circumferential direction, in relation to the first axis. The second gearing element is supported at N+1 contact points of the first gearing element, wherein N is at least two.

Abstract: A torque-transmitting arrangement for the drive train of a muscle-power-operated vehicle with auxiliary motor includes an output shaft, a first input shaft for the transmission of a torque generated by muscle power to the output shaft, a second input shaft for the transmission of a torque generated by the auxiliary motor to the output shaft, and a freewheel function, which prevents a user from having to concomitantly rotate the auxiliary motor when the auxiliary motor is inactive. A mechanical clutch transmits a torque from the second input shaft to the output shaft if, at the first input shaft, a torque prevails which acts in a drive direction of rotation on the output shaft, and transmits no torque from the second input shaft to the output shaft if, at the first input shaft, a torque prevails which acts on the output shaft counter to the drive direction of rotation.

Abstract: The present disclosure relates to a transmission having a ring gear in which a flexible gearwheel is arranged, where the flexible gearwheel is connected to a wave generator and the wave generator deforms the flexible gearwheel such that it is in engagement in some regions with the ring gear. The flexible gearwheel includes at least two toothed segments which are connected to one another by way of spring segments and at least one of the toothed segments includes a recess in which a pin element is arranged.
