An auxiliary power take-off assembly in a motor vehicle transmission, which has a torque converter, a transmission input and a transmission output. The auxiliary power take-off assembly includes: an input shaft at the transmission input, and which is permanently connected to a drive motor of the motor vehicle by way of the pump shaft of the torque converter; a transmission output shaft at the transmission output; a transmission chain, which includes an input element and an output element and the output element of which can be connected to an auxiliary assembly to be driven; and a switching element, which is operatively arranged between the input shaft and the input element of the transmission chain, to selectively connect the input shaft to the output element. The output element is arranged on an output shaft, which is mounted in a bearing cap.

Auxiliary power take-off assembly

An auxiliary power take-off assembly in an automatic transmission of a motor vehicle provided with a torque converter, having a transmission input and transmission output having a drive shaft at the transmission input that is permanently connected to a drive motor of the motor vehicle via a pump shaft of the torque converter. A transmission output shaft at the transmission output, and a transmission chain includes at least one drive element and one output element. The output element can be connected to an additional unit to be driven. A switch element, which is arranged so as to act between the drive shaft and the drive element of the transmission chain for optionally connecting the drive shaft to the drive element. The drive element and the output element are designed as gearwheels which are engaged with one another without an intermediate wheel.

An auxiliary power take-off assembly in a motor vehicle transmission having a torque converter, transmission input and output with a drive shaft on the transmission input. The drive shaft is permanently connected to a drive motor of the vehicle by a pump shaft of the torque converter, a transmission output shaft at the transmission output and a transmission chain having drive input and output elements. A transmission power take-off shaft on the transmission output and a transmission chain having at least a drive element and a power take-off element of which the power take-off element can be connected to an additional unit to be driven, and having a switching element. The power take-off element is arranged on a power take-off shaft and can be connected to the power take-off shaft via the switching element, which is arranged to act between power take-off shaft and the power take-off element.

A motor vehicle transmission having an input shaft, which can be coupled to a drive aggregate, an output shaft, which can be coupled to an output, and several shift elements. At least two shift elements, designed as clutches, are each coupled via an outer clutch plate carrier with the input shaft in such a way that an outer clutch plate carrier of a first radially outer clutch encloses an outer clutch plate carrier of a second radially inner clutch at least sectionally and radially outside. A drive gear is coupled to the input shaft through which a power take-off can be coupled to withdraw power from the input shaft or through which an auxiliary drive aggregate can supply power to the input shaft. The drive gear is linked through the outer clutch plate carrier of the radially inner clutch to the input shaft.
