Abstract: A steering and drive system for toy vehicles is disclosed. Independent gear trains for wheels on opposite sides of the toy vehicle are utilized in combination with a single reversible motor to either rotate all wheels in the same direction to move the vehicle in a straight line or, by reversing the direction of the motor, to rotate wheels on opposite sides of the vehicle in opposite directions causing the vehicle to turn. Wheels on one side of the vehicle are connected to a main gear and the direction of rotation of such wheels is completely dependent upon the polarity of an electric power source applied to the motor. Wheels on the opposite side of the vehicle are indirectly connected to the main gear by a movable control gear which is urged to engage either an auxiliary gear or a second side drive gear so that the wheels rotate in only a single direction regardless of the direction of the motor.

Abstract: A steering mechanism for self-powered vehicles and vehicles employing this mechanism are disclosed. The steering mechanism is characterized by a yoke pivotably attached to the vehicle frame which carries one of the vehicle's axles. A crown gear is provided on the axle which engages a spur gear mounted on the yoke in a position substantially perpendicular to the crown gear. The spur gear is connected through a drive train to a reversible motor. Stops are provided on the frame or yoke which hold the axle substantially parallel to the vehicle's other axle when the motor is turning in a given direction. Then the axle is positioned so that the vehicle will travel in a straight line. When the motor is reversed the stops will allow the yoke and attached axle to pivot to a postion where the axles are no longer parallel and the vehicle will turn.
