Claims29
A releasable axle assembly comprising:
- a quick release configured to be attached to an axle that is solid throughout its length and is a load bearing member, wherein the solid axle has a first threaded portion and a second threaded portion thereon at opposing ends of the solid axle, wherein the solid axle is fixed in position in relation to horizontal movement about an axis of a hub and wherein the quick release comprises:
- a tubular nut having a threaded portion at a first end corresponding to said first threaded portion of said solid axle;
- a lever for moving a cam such that said quick release is moved relative to said solid axle along a path substantially parallel and co-axial with said solid axle;
- a transfer member positioned between the cam and a frame or fork to transfer a retaining force from the lever to the frame or fork, wherein the transfer member comprises an opening sized to allow the first end of the tubular nut to pass through the transfer member;
- wherein the tubular nut attaches the quick release to the solid axle;
- wherein said quick release is attachable to the solid axle, wherein a diameter of said first threaded portion of said solid axle and said second threaded portion of said solid axle is greater than 0.125 inches.

A vehicle having at least one wheel comprising:
- a wheel comprising a hub;
- a frame;
- a releasable axle assembly having:
- a pair of quick releases per wheel;
- an axle having a first threaded portion and a second threaded portion thereon at opposing ends of said axle;
- wherein said axle is load bearing and solid throughout its length;
- wherein the pair of quick releases comprises a first quick release and a second quick release for use with said solid axle;
- wherein a threaded portion at a first end of said first quick release corresponds with said first threaded portion of said solid axle;
- wherein a threaded portion of said second quick release corresponds with said second threaded portion of said solid axle;
- a lever on each of said first quick release and said second quick release for moving a cam on each of said first quick release and said second quick release such that said first quick release and said second quick release are moved relative to said solid axle along a path substantially parallel and co-axial with said solid axle;
- a transfer member positioned between the cam and the frame to transfer a retaining force from the lever to the frame, wherein the transfer member comprises an opening sized to allow the first end of the tubular nut to pass through the transfer member;
- wherein the quick release assembly is configured to be attached to the solid axle, which is fixed in position in relation to horizontal movement about an axis of the hub of the wheel;
- and
- wherein said solid axle has a diameter of said first threaded portion and said second threaded portion greater than 0.125 inches.
