  • Patent number: 6709013
    Abstract: There is disclosed lever steering apparatus for a land vehicle with steerable and independently suspended front wheels having left and right steering levers at the driver position. The left and right steering levers are coupled by lever mechanisms and an elongated rod to move in opposite directions. Left and right fore and aft links extend from the left and right steering levers to the left and right front wheels to transmit steering motion displacement to the steerable front wheels causing rotation of the axles of the wheels about a vertical axis. A controller arm connected to each wheel stub axles is connected to the forward end of a fore and aft link for steering motion of a front wheel. The control arm fore and aft link combination causes each wheel steering motion to have a predetermined relation to motion of the corresponding link.
