Abstract

A hub of a bicycle wheel or the like rotatably mounted on an axle and bearing assembly. The assembly consists of an axle and bearings for supporting the specially formed hub which are separable but are ordinarily kept in assembled condition in the hub by a quick-release cam lock or clamp.

Claims

1. A wheel-supporting assembly comprising a hub having a central sleeve and outwardly-opening concentric bearing-receiving sockets at its opposed ends, concentric bearing units slipped into said sockets, a spacer sleeve concentric within the central sleeve into which it is slipped and having opposed ends engage the bearing units, an axle sleeve slipped through said spacer sleeve and the aligned bearing units and having its ends projecting outwardly from the respective bearing units, concentric cups disposed on the outer ends of said axle sleeve and having inwardly projecting skirts for engagement with the respective bearing units, each of said cups having portions fitting into mounting openings in wheel-supporting frame members, and means for holding the assembled parts axially together and within said members.

2. An assembly according to claim 1 in which said last named means comprises a rod extending through said axle assembly and said caps and having its opposite ends projecting therefrom, said end having thrust caps mounted thereon for axial adjustment towards and from each other so that they can be moved into engagement with the respective frame members to clamp them between the adjacent cups and caps.

3. An assembly according to claim 2 in which said rod and cap are part of a quick-release clamp, said clamp having one of the caps fixed thereon at one end against axial movement and the second cap mounted thereon for axial movement.

4. An assembly according to claim 3 in which both caps carry threaded sockets receiviNg threaded ends of the rod the second cap having its threaded socket in an eccentric mounted for rotation in a transverse bore within the cap.

5. An assembly according to claim 4 in which the eccentric in the transverse bore consists of a pair of opposed eccentric members rotatably mounted in the bore, said rod slidably extending into the cap and the bore thereof and being threaded into a transverse connecting member disposed axially within the bore and on which said eccentrics are rotatably mounted, and a handle connected to said eccentrics for rotating them simultaneously within the cap bore to move the cap axially of the rod and into engagement with the adjacent frame member.

6. An assembly according to claim 2 in which before clamping the cup skirts are axially spaced from the bearing units and the ends of the axle sleeve are in contact with the closed ends of the cups but after clamping the skirts of the cups are in contact with the bearing units.
