  • Patent number: 6485042
    Abstract: An integrated rotary drive motion transmission and directional control system includes a rotor and a pair of rotary drive motion transmitting assemblies each disposed adjacent to one of the opposite sides of the rotor. The rotor is mounted to rotate in either of opposite directions and has an annular channel defined on each opposite side by radially spaced inner and outer concentric surfaces. Each assembly is mounted to rotate in either opposite direction and has output and input elements disposed respectively remotely from and adjacent to the rotor. The input element can be moved from an intermediate neutral position to one of opposite drive positions where the input element engages one or the other of the inner and outer surfaces of the rotor annular channel enabling transmitting of rotary drive motion from the rotor to the assembly output element and controlling speed and direction thereof.
