Abstract
A motor driven wheeled toy is provided with a driven axle that swivels in a vertical plane transverse to the direction of movement of the vehicle. More than one of such driven axles, each swiveling independent of the other, may also be provided. The vehicle motor drives an elongated shaft that is transverse to the axle. Respective gears are carried by and rotate with the shaft and the axle for transmitting power between the shaft and the axle. A connector having substantially right angle plates is carried by the shaft for rotation around the axis of the shaft. The shaft fits through a bearing aperture in the end plate of the connector. The axle extends through an opening in the transverse side plate of the connector which permits the axle to rotate with respect to the connector and to swivel together with the connector around the axis of the shaft. The wheels mounted on the ends of the axles for rotation with the axles are of a soft resilient material and have a large diameter to permit movement of the vehicle over rough surfaces and obstacles.
