Abstract: The subject invention provides a wheel assembly (20) having a spindle (26) for attachment to a vehicle along a rotational axis (R). An electric motor (22) is disposed radially about the spindle (26) and includes a stationary stator (34) and a rotor (36) rotatable about the rotational axis (R) relative to the stator (34). A rotor support (40) is disposed about the spindle (26) and includes a collar (42) rotatably supported by at least one rotor support bearing (46) on the spindle (26). The rotor support (40) includes a flange (44) disposed within a predetermined axial distance (D) and extending radially outward from the collar (42) to support the rotor (36). A planetary gear system (62) interconnects the rotor support (40) and a wheel drive (52) for reducing rotational speed of the rotor (36) and increasing the torque of the wheel assembly (20).

Abstract: A kinematic arrangement of an automatic transmission includes three simple planetary gear units having certain elements fixed to other elements mutually, a one-way coupling for holding the ring gear of the first gear unit against rotation, brakes for holding the carrier of the third gear unit and the sun gears of the second and third gear units against rotation on the transmission housing, two friction clutches arranged in parallel between the input shaft and the sun gears of the second and third planetary gear units, a brake band for holding the ring gear of the third gear unit and carrier of the second gear unit against rotation, and a friction clutch for holding the sun gear of the first gear unit against rotation.

Abstract: An automatic transmission for a motor vehicle includes two layshaft gearsets, three planetary gear units, friction clutches, friction brakes, and an overrunning coupling. The input shaft of the transmission is adapted to drive elements of the planetary gear units. An alternate arrangement replaces the layshaft gearsets with chain drive mechanisms.

Several input shafts of the transmission are adapted to drive elements the sun gears and a ring gear of the planetary gear units.

Abstract: A multiple-speed automatic transmission for automotive vehicles able to produce three underdrive speed ratios, a near direct ratio, and two overdrive ratios. A kinematic arrangement includes three simple planetary gear units (48, 50, 52). One of these produces an underdrive output drivably connected to components of the other gear units, three friction clutches (118, 120, 122) to friction brakes (124, 126), an overrunning coupling (82), a final drive gearset (94), a differential mechanism (102), a chain drive mechanism (30) for transmitting power from the turbine (16) of a torque converter (10) to the input shaft, which drives elements of the planetary gear units.

Abstract: A multiple-speed transmission for use in an automotive vehicle driveline includes a torque converter, three simple planetary gear units, one-way clutches and brakes, friction clutches, and friction brakes. The engaged and disegaged state of the friction elements permit the transmission to produce several underdrive speed ratios, a direct drive ratio, and several overdrive ratios.

Abstract: A shaft connected to a component of a planetary gearset is driveably connected by a coupling to alternate friction elements in accordance with the relative speeds of the coupling members and the direction of rotation of the driven coupling member. The coupling includes a radially inner one-way coupling and an outer one-way coupling, the outer race of the inner coupling and inner race of the outer coupling being the intermediate race, which is connected to the gearset. The inner race and outer race have cam surfaces contacting roller clutch elements located in a cage and spaced mutually about the coupling axis. The cam surfaces of the races are inclined with respect to the adjacent surface of the intermediate race in opposite directions, so that when one coupling drives, the other coupling overruns.
