in the traction band, and also may be positioned to be in cooperation with the plurality of spaced apart protrusions in the chamber portion. Further, the spaced apart protrusions in the chamber portion may extend at least part way into the spaced apart holes of the traction band when the wheel assembly is loaded with the weight.
In one aspect, the resilient member is adapted to stretch at least part way into the spaced apart actuator band holes when the wheel assembly is loaded with the weight. The weight may include a motorized vehicle, a non-motorized vehicle, a person or persons, freight, and the like.
In alternative aspects, the traction layer comprises a substantially incompressible rubber, the resilient member comprises a rubber, and the chamber portion and the actuator comprisepresent invention, a wheel assembly includes a traction layer disposed over an actuator, with the traction layer and actuator each having a plurality of holes disposed therethrough, and with the traction layer holes in alignment with the actuator holes. The assembly further includes a chamber portion adapted to be coupled to a wheel rim, the chamber portion having inner and outer edges defining a recessed bottom therebetween having a plurality of spaced protrusions. A resilient member is disposed between the chamber portion and the actuator. The resilient member is adapted to stretch into the chamber portion between the spaced protrusions, and is adapted to stretch at least part way into the actuator holes over the spaced protrusions.
In a particular aspect, the traction layer, actuator, chamber portion and resilient
