  • Patent number: 7766785
    Abstract: A multiple-speed automatic transmission includes an input, output, a first gear unit drivable connected to the input and including a component rotating at the speed of the input and a first gear unit output, the first gear unit producing a gear ratio of a speed of the input and a speed of a first gear unit output, the gear ratio being greater than unity, and a Ravigneaux gear unit for producing multiple ratios of the speed of the input and a speed of the output, the Ravigneaux gear unit being driveably connected to first, second, third, fourth, fifth and sixth rotating members and the output.
    Type: Grant

  • Patent number: 7509802
    Abstract: An apparatus for supporting an electric power source in a transmission includes a transmission housing, and an electric machine including a rotor and a stator secured to the housing. A first member is secured to the rotor, extends radially toward an axis of rotation, and is formed with a first pilot surface. A second member, secured to the rotor and the housing, extends from the housing toward the axis and is formed with a second pilot surface that is aligned axially with the first pilot surface. An anti-friction bearing, located at an axial rearward side or axially frontward side of a torque converter, is engaged with the first pilot surface and the second pilot surface. A second balanced bearing is located either in the driving engine or the driven transmission.

  • Patent number: 7294089
    Abstract: An automatic transmission includes a first power path producing a first ratio of a speed of the input and a speed of a first power path output; a second power path producing a second ratio of a speed of the input and a speed of the second power path output, the second ratio being is less than the first ratio; a double planetary gear unit including first, second, third and fourth members, the second member being secured to the output; a first clutch being operable to connect the first member to the input through the first power path; a second clutch being operable to connect the fourth member to the input through the first power path; a third clutch being operable to connect the third member carrier to the input through the second power path; a fourth clutch being operable to connect the fourth member to the input through the second power path; a first brake being operable to hold the fourth member against rotation; and a second brake being operable to hold the third member against rotation.

  • Patent number: 7235032
    Abstract: A multi-speed automatic transmission includes an input and output, first, second and three planetary gear units, each gear unit including a sun gear, a ring gear, planet pinions meshing with the sun gear and the ring gear, and a carrier rotatably supporting the planet pinions. A first brake alternately holds against rotation and releases the sun gear of the second gear unit and the sun gear of the third gear unit. A second brake alternately holds and releases the carrier of the second gear unit. A first clutch alternately connects and disconnects the carrier of the first gear unit and the ring gear of the third gear unit. A second clutch alternately disconnects and connects the carrier of the first gear unit to the sun gears of the second gear unit and third gear unit. A third clutch alternately releases and connects the input and ring gear of the first gear unit to the carrier of the second gear unit.
