Abstract
An electrically energized toy racing car is provided which includes an improved steering mechanism that permits the car to be steered to the right or left depending upon the polarity of the direct-current voltage applied to its drive motor. The car is intended to be raced on a specially constructed track which includes electrically conductive strips extending along its length, the strips providing electrical energizing current for the drive motor. The steering is accomplished by a gear train which causes the front or rear axle of the car to turn in a limited amount in one direction or the other depending upon the polarity of the voltage applied to the drive motor, as the car is driven in the forward direction.
Claims5
A toy car including:
- a chassis;
- an electrically energized drive motor mounted on the chassis and having a drive shaft;
- a plurality of wheels for the car mounted on the chassis;
- an axle for supporting two of the wheels at the respective ends thereof, each of said wheels including a hub clamped to the axle and each of the hubs having a gear affixed thereto;
- means for mounting the axle on the chassis for angular movement thereof about a vertical axis for steering purposes;
- and means including a gear train coupling the drive shaft of the motor to the axle for transmitting forward motion to the car and for causing the axle to turn angularly in one direction of the other about the vertical axis depending upon the direction of rotation of the motor, said gear train including a drive gear, a pivotally mounted arm supporting the drive gear on its distal end and angularly movable about a pivot axis to cause the drive gear selectively to engage the gears affixed to the hubs of the two wheels, a further gear coaxial with said drive gear and affixed thereto, and gear means coupling the further gear to the drive shaft of the motor.
