摘要:
A transmission includes a coaxial input member, output member, intermediate member, and simple planetary gear set. A first and a second layshaft are arranged to define a second 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 one of the intermediate member and the simple planetary gear set. The transmission has eight torque-transmitting mechanisms that are each selectively engagable to connect a different respective gear of the intermeshing sets of gears to a respective one of the layshafts or to a stationary member. The torque-transmitting mechanisms are engagable in different combinations to establish up to fourteen forward speed ratios and a reverse speed ratio between the input member and the output member.
