ABSTRACT:
A quick release coupling for a wheel and axle comprising an axle having an outer end for receiving a wheel thereon, a circumferential ball receiving groove adjacent the end of the axle, a wheel having a hub portion with a central opening therein for receiving the end of the axle, a bushing mounted on the hub surrounding the central opening for receiving the end of the axle, intermating splines on the axle and bushing for preventing relative rotational movement of the wheel and the axle, a plurality of circumferentially arranged and spaced ball receiving holes in the bushing overlying the ball receiving groove when the axle is in a locked position relative to the wheel, a plurality of balls received in the ball receiving holes, a locking sleeve slidably and axially mounted on the bushing, a first spring for urging the sleeve towards the wheel, a plunger centrally mounted within the bushing, a second spring for urging the plunger against the end of the axle, a stop for limiting the axial movement of the sleeve towards the wheel, the sleeve having an internal cylindrical surface overlying the balls in the locked position to hold the balls in the ball receiving groove, the sleeve being provided with an internal ball receiving recess of larger diameter than that of the flat cylindrical surface and located inwardly thereof towards the wheel, and handles on the sleeve for manually pulling the sleeve axially away from the wheel to permit the balls to drop into the ball receiving recess thereby permitting withdrawal of the wheel from the axle, the plunger, after the wheel has been withdrawn from the axle, moving towards the balls and retaining the balls in the ball receiving recess.
