Abstract

A multi-speed transmission for an engine driven agricultural or construction vehicle is comprised of an epicyclic torque-splitting gear arrangement driven by an input assembly. The input assembly, driven by the engine through a drive engagement means, includes a reversing planetary gear arrangement. The epicyclic torque-splitting gear arrangement includes an input member driven by the input assembly, an output member and a reaction member. The reaction member of the epicyclic torque-splitting gear arrangement is drivingly interconnected with a speed reduction means. The speed reduction means is also driven by the input assembly, and is selectively controllable for rotating the reaction member of the epicyclic torque-splitting gear arrangement in one or the other directions relative to the direction of rotation of the input assembly. The speed reduction means is further controllable to stop rotation of the reaction member relative to rotation of the input assembly.
