  • Patent number: 5161813
    Abstract: A vehicle steering apparatus includes a steering mechanism adapted to transmit a steering angle of a steering wheel through a link mechanism to a wheel. The vehicle steering apparatus includes an angle increasing gear set disposed between the link mechanism and the wheel for increasing the steering angle of the steering wheel to be transmitted to the wheel. The angle increasing gear set and the wheels are supported by a vehicle frame through a suspension. The angle increasing gear is formed of an internal gear wheel connected to the link mechanism and an external gear wheel connected to the wheel and meshing with the internal gear wheel.

  • Patent number: 5150763
    Abstract: A wiring and piping arrangement for a vehicle motor comprises a wheel motor connected to a wheel, a wheel support member connected to a vehicle frame through a damper, an internal gear rotatably supported on the wheel support member, and a pivot fixed to a casing of the wheel motor. The pivot is provided with an external gear meshing with said internal gear. The arrangement further comprises a wiring and/or piping for the wheel motor extended through an interior or said pivot. Since the wirings and pipings are extended through the pivot for a steering operation of the wheel motor, the wiring and/or piping are required to have slacks or extra lengths which allow only the vertical movement of the wheel, and are not required to have the slacks for allowing the lateral movement of the wheel.
