  • Selectable torque path torque converter architecture
    Patent number: 12228191
    Abstract: An architecture for coupling the output of a prime mover to a rotationally driven device. The architecture includes a selectable switching device, a terminal output member and a torque transfer device having an intermediate output member. The selectable switching device is coupled to the output of the prime mover and is selectively and alternately coupled between first and second states; in the first state with the torque transfer device, whereby the torque transfer device is rotatably driven by the prime mover and the terminal output member is rotatably driven by the intermediate output member of the torque transfer device; and in the second state with the terminal output member, whereby the terminal output member is rotatably driven by the prime mover and the torque transfer device is rotatably disconnected from the prime mover and is not rotatably driven.

  • Three position gear selection unit
    Patent number: 12181029
    Abstract: A gear reduction unit for coupling the output member of a prime mover to the input member of a device that is to be driven thereby. The gear reduction unit includes an input shaft, an output shaft, a primary gear set arranged between the input shaft and the output shaft, a secondary gear set arranged between the input shaft and the output shaft, and a gear selection device. The gear selection device is configured to selectively and alternately couple the input shaft to the output shaft for driving thereof by one of the primary gear or the secondary gear set.
