ABSTRACT:
A wheel includes a hub having a number of teeth formed on one end. A cam is rotatably supported on one end of the hub. An axle is rotatably engaged in the hub and has one end engaged with the cam. A spring biases the axle to engage with the cam. A coupler is rotatably engaged on the axle and includes a key for engaging with the teeth of the hub when the spring biases the axle toward the cam, and the key is disengaged from the teeth when the axle is moved against the spring by the cam. The wheel can be applied to push carts or applied to motor vehicles.
