Abstract:
1. A three wheeled vehicle rear steering mechanism for improving steering by turning the rear wheels in coordination with the front wheel, comprising: means for sensing any left or right turning movement of the front wheel; means for connecting front wheel position sensor to steering computer, electrically connected to said means for sensing any left or right turning movement of the front wheel; means for controlling rear steering system and deciding degree and direction to deflect rear wheels, electrically connected to said means for connecting front wheel position sensor to steering computer; means for providing the mechanism for attaching the left rear wheel assembly to the vehicle and a mechanism for the rear steering assembly to move the left rear wheel assembly left and right; means for providing the mechanism for attaching the right rear wheel and tire assembly to the vehicle and a mechanism for the rear steering assembly to move the right wheel and tire assembly left and right; means for detecting the deflection of the left rear wheel as it relates to the longitudinal axis of the vehicle; means for connecting the left rear wheel position sensor to the steering control computer, electrically connected to said means for detecting the deflection of the left rear wheel as it relates to the longitudinal axis of the vehicle, and electrically connected to said means for controlling rear steering system and deciding degree and direction to deflect rear wheels; means for detecting the deflection of the right rear wheel as it relates to the longitudinal axis of the vehicle; means for connecting the right rear wheel position sensor to the steering control computer, electrically connected to said means for detecting the deflection of the right rear wheel as it relates to the longitudinal axis of the vehicle, and electrically connected to said means for controlling rear steering system and deciding degree and direction to deflect rear wheels; means for moving the rear wheels according to the signal from the rear steering control computer; means for controlling the movement of the rear steering assembly as it receives input from the steering control computer, electrically connected to said means for moving the rear wheels according to the signal from the rear steering control computer; means for providing power to the steering mechanism, electrically connected to said means for moving the rear wheels according to the signal from the rear steering control computer; means for connecting the left rear wheel steerable hub to the steering assembly for the purpose of transmitting movement from the steering assembly to the left rear wheel steerable hub, mechanically connected to said means for moving the rear wheels according to the signal from the rear steering control computer, rotationally attached to said means for detecting the deflection of the left rear wheel as it relates to the longitudinal axis of the vehicle, and mechanically connected to said means for providing the mechanism for attaching the left rear wheel assembly to the vehicle and a mechanism for the rear steering assembly to move the left rear wheel assembly left and right; means for connecting the right rear wheel steerable hub to the steering assembly for the purpose of transmitting movement from the steering assembly to the right rear wheel steerable hub, mechanically connected to said means for moving the rear wheels according to the signal from the rear steering control computer, rotationally attracted to said means for detecting the deflection of the right rear wheel as it relates to the longitudinal axis of the vehicle, and mechanically connected to said, means for providing the mechanism for attaching the right rear wheel and tire assembly to the vehicle and a mechanism for the rear steering assembly to move the right wheel and tire assembly left and right; means for providing a means for attaching the steering shaft to the steerable wheel hub, rotationally connected to said means for connecting the right rear wheel steerable hub to the steering assembly for the purpose of transmitting movement from the steering assembly to the right rear wheel steerable hub; means for measuring vehicle road speed; and means for allowing operator to engage and disengage the rear steering system.
