Patent number: 11813938Abstract: 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.Type: GrantFiled: February 27, 2019Date of Patent: November 14, 2023Assignee: ZF Friedrichshafen AGInventors: Michael Epple, Michael Trübenbach, Hermann Lanz, Sylva Rother, Mario Holder

Patent number: 11479116Abstract: 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.Type: GrantFiled: February 27, 2019Date of Patent: October 25, 2022Assignee: ZF Friedrichshafen AGInventors: Michael Epple, Michael Trübenbach, Hermann Lanz, Sylva Rother, Mario Holder
