A drive device for a hybrid-driven motor vehicle includes a primary drive, a secondary drive, and a variable speed gearbox. The primary and secondary drives are configured to drive the gearbox separately or jointly. The gearbox includes a first input shaft connectable to the primary drive, a second input shaft connectable to the secondary drive, an output shaft, and switching elements. In a first state of the gearbox, a rotational movement of a first fixed toothed wheel of a first intermediate shaft is synchronously coupled with a rotational movement of the output shaft by a first switching element. In a second state, a rotational movement of a first idler toothed wheel on the first input shaft is synchronously coupled with a rotational movement of a second idler toothed wheel on the first input shaft by a second switching element.

Drive device for a hybrid-driven motor vehicle, and motor vehicle associated therewith

A coupling assembly is provided for a transmission assembly, in particular for a multiple spider planetary gear transmission, wherein the transmission assembly has two speed-change gear units coupled to each other. A first shaft and a second shaft are coupleable with one of the speed-change gear units, wherein by blocking of one of the shafts two shifting stages of the transmission assembly are shiftable. A third shaft is provided as well as a first shifting element and a second shifting element, each of which couples the first shaft and the second shaft with the third shaft. A third shifting element is provided which can brake and/or block the third shaft.

Coupling assembly and transmission assembly

A drive arrangement for a drive train of a vehicle is disclosed. In one aspect, the drive arrangement includes at least one transmission element configured to transmit a force and/or a torque and at least one joint. The transmission element and the joint are configured to be connected reversibly in a force transmitting manner and/or in a torque-transmitting manner.
