Abstract:
1. Power transmission unit for an electromotively operated drive, wherein the power transmission unit comprises: a first input shaft and a second input shaft; a motor shaft for driving the first and the second input shafts together in opposite directions; a driven shaft for coupling, depending on a desired sense of rotation of the driven shaft, with the first or the second input shaft, and for engaging with a first output shaft and with a second output shaft; a first magneto-rheological clutch between the first input shaft and the first output shaft for directly coupling the first output shaft with the first input shaft; and a second magneto-rheological clutch between the second input shaft and the second output shaft for directly coupling the second output shaft with the second input shaft; wherein the first and the second magneto-rheological clutches each comprise: one coil for creating a desired magnetic field, wherein a power supply of the coil includes means for wireless energy transmission between a sender connected to a stationary housing and a receiver with which the coil is to rotate.
