ABSTRACT:
The skateboard wheel and axle assembly includes an axle rigidly mounted in a hangar, with opposite ends of the axle extending from the hangar. Each end of the axle has an axial blind bore defined therein closed by an end cap and a plurality of holes defined radially adjacent the end cap. A spring-biased detent pin slidably mounted in the bore urges a plurality of detent balls to partially extend from the radially disposed holes. The detent balls engage an annular groove defined in the inner race of the outer wheel bearing to retain the wheel on the axle. The detent pin has a release arm extending through aligned slots in the axle and the hangar that can be retracted, compressing the bias spring, in order to withdraw the detent balls from the groove so that the wheel can be pulled off the axle.
