摘要： A wheel assembly is disclosed. The wheel assembly may have a hub with a first spline, a second spline, and a slot separating the first spline and the second spline. The first spline, the second spline, and the slot may extend from a front end to a rear end. The wheel assembly may also have an outer rim configured to mount a tire. The wheel assembly may further have an inner rim extending from a rim front end to a rim rear end. The inner rim may have a notch disposed at the rim front end and a tab disposed at the rim rear end. The tab may slidingly engage with the slot. The wheel assembly may have a locking block, which may slidingly engage with the notch and the slot at the front end. Further, the wheel assembly may have a bolt connecting the mounting block to the hub.
