The present invention provides exemplary vehicle wheel assemblies for use with a wide range of wheeled vehicles and apparatus. In one embodiment, a wheel assembly (100) includes first and second rim portions (210, 212) having edges (220, 222). The wheel assembly includes a cartridge disposed in a trough portion between the rim edges. The cartridge includes a chamber portion (300) having a plurality of spaced protrusions (310), a resilient member (400) disposed over the plurality of spaced protrusions, an actuator (500) disposed over the resilient layer, and a traction layer (600) disposed over the actuator. The actuator is adapted to compress the resilient layer at least partially into the chamber portion when the wheel assembly is loaded with a weight. In this manner, the wheel assembly is capable of providing energy return to the wheel assembly during rotation thereof. |
