  • Patent number: 11261957
    Abstract: Systems and methods for operating a driveline system are disclosed and include a step-variable transmission. A continuously variable transmission (CVT) is coupled between an input source and the step-variable transmission. The CVT receives a first torque from the input source and outputs a second torque. The CVT has a plurality of planetary members in rolling contact with an inner race and an outer race. A radial distance between the planetary members and a drive-transmitting member corresponds to a transmission ratio of the CVT.

  • Patent number: 10539214
    Abstract: An integrated pinion, bearing and coupling (PBC) assembly for use with a hypoid gearset in power transfer assemblies of motor vehicles. The PBC assembly includes a pinion unit having a pinion gear segment and a pinion stub shaft segment, and a coupler unit having a coupling flange segment and a coupler shaft segment. The pinion stub shaft segment surrounds and is in press fit engagement with the coupler shaft segment. A portion of the coupler shaft segment is deformed to be retained within one of a receiver groove and raised projections formed in the pinion stub shaft segment so as to fixedly secure the coupler unit to the pinion unit.

  • Patent number: 10443692
    Abstract: A system has a pump with a power input, a power source and a continuously variable transmission (CVT) coupled to the power source and to the power input of the pump. The CVT transmits power from the power source to the pump. The CVT comprises a plurality of planetary members in rolling contact with an inner race and an outer race. A radial distance between the planetary members and a drive-transmitting member corresponds to a transmission ratio of the CVT.
