  • Patent number: 8540600
    Abstract: A multi-speed transmission includes an input member, an output member, a stationary member, and a first and a second compound planetary gear set. The first compound planetary gear set has a first, a second, a third, a fourth, and a fifth member. The second compound planetary gear set has a first, a second, a third, and a fourth member. The first member of the second compound planetary gear set is continuously connected for common rotation with the output member. An interconnecting member continuously connects the first member of the first compound planetary gear set for common rotation with the second member of the second compound planetary gear set. The transmission has seven torque-transmitting mechanisms, including three brakes and four rotating-type clutches, that are engagable to establish up to fourteen forward speed ratios between the input member and the output member.

  • 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.

  • Patent number: 8398524
    Abstract: A transmission includes an input member, an output member, an intermediate shaft, and a simple planetary gear set, all of which are coaxial. A first and a second layshaft are arranged to define a second axis of rotation and a third axis of rotation, respectively. The transmission has five sets of intermeshing gears, some of which are arranged to transfer torque from the input member to the layshafts, and others of which are arranged to transfer torque from the layshafts to the intermediate member or the simple planetary gear set. The transmission has eight torque-transmitting mechanisms, including one torque-transmitting mechanism that is selectively engagable to connect the input member for common rotation with the intermediate member. The other seven torque-transmitting mechanisms are each selectively engagable to connect a different respective gear of the sets of intermeshing gears to a respective one of the layshafts or to a stationary member.
