  • Multi-speed electric machine gearbox with low drive ratio
    Patent number: 11015689
    Abstract: A gearbox includes an input gear supported for rotation about an input axis and includes first and second idler gears fixedly coupled to each other and supported for rotation about a transfer axis. The first idler gear is fixedly coupled to the input gear. A planetary gear set is supported for rotation about an output axis of the gearbox and has a first component fixedly coupled to the second idler gear. A differential is supported for rotation about the output axis, co-axial with the planetary gear set, and fixedly coupled to a second component of the planetary gear set.
    Type: Grant

  • Transmission assembly
    Patent number: 10119597
    Abstract: The output gear of a transmission is externally supported from an interior support by two ball bearings. The output gear is fixed to a shell. A carrier of a simple planetary gear set and a ring gear of a stepped pinion planetary gear set are splined to the shell. A brake includes a piston supported by the bell housing and clutch plates splined to the interior support.
