Motor driven wheeled toy with floating driven axle
First Claim
1. A motor driven toy with ground engaging wheels comprising:
- a chassis;
a rotatable drive shaft with an axis carried by the chassis;
a power connection connectable to a motor and the shaft to rotate the shaft;
a first axle with an axis and ends disposed transverse to the shaft;
a wheel mounted on each end of the first axle for movement with the axle;
a first connector means carried by the shaft and carrying the first axle for rotation around the first axle axis and to swivel about the axis of the shaft;
power transmission means between the shaft and the first axle that remains engaged while the first axle swivels about the shaft;
a second axle with an axis and ends disposed transverse to the shaft;
a wheel mounted on each end of the second axle for movement with the second axle;
a second connector means carried by the shaft and carrying the second axle for rotation around the second axle axis and to swivel about the axis of the shaft; and
power transmission means between the shaft and the second axle that remains engaged while the second axle swivels about the shaft.

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.
