  • Compact split torque transmission for wide overall ratio coverage
    Patent number: 11499615
    Abstract: An automobile vehicle split torque transmission includes an electrical motor having a rotor drive shaft with a drive pinion attached to the rotor drive shaft, the rotor drive shaft defining a first axis. A first transfer gear is mounted on a first transfer gear shaft defining a second axis, the first transfer gear meshed with the drive pinion. A second transfer gear is mounted on a second transfer gear shaft defining a third axis, the second transfer gear meshed with the drive pinion. A differential ring gear is supported on a differential shaft and rotates a differential assembly, the differential shaft defining a fourth axis.
    Type: Grant

  • Hydraulic control system for an automatic transmission
    Patent number: 10495214
    Abstract: A hydraulic control system for a transmission of a motor vehicle includes a source of pressurized hydraulic fluid that communicates with an analog electronic transmission range selection (ETRS) subsystem or a manual valve. The ETRS subsystem includes an ETRS valve, a park servo, a park mechanism, a mode valve, and a plurality of solenoids. The ETRS and manual valve communicate with a clutch actuator subsystem that engages a one-way clutch and six clutches/brakes.
