  • Transmission with mixed planetary layshaft structure
    Patent number: 8439787
    Abstract: A transmission includes an input member, an output member, a first and a second intermediate member, and a planetary gear set, all of which are coaxial and define a first axis of rotation. A first and a second layshaft are arranged to define a second axis of rotation and a third axis of rotation, respectively. Each of five sets of intermeshing gears transfer torque from a respective one of the intermediate members to a respective one of the layshafts via engagement of different respective ones of nine torque-transmitting mechanisms. A set of transfer gears transfers torque from the layshafts to the output member. One of the torque-transmitting mechanisms grounds a member of the planetary gear set to a stationary member. The nine torque-transmitting mechanisms are engagable in different combinations to establish up to eight forward speed ratios and at least one reverse speed ratio.
