Abstract
A connection for quickly mounting and removing wheels from a trailer, without removing or replacing lug nuts. The wheel assembly includes a non-rotating shaft or axle which serves as its journal. This journal is inserted and received snugly within a sleeve rigidly secured to the frame of the trailer, and pin and other connecting elements are added to prevent relative rotation and axial movement between journal and sleeve. Various embodiments are disclosed, including a simple pin dropped into aligned transverse openings in the two members and interfitting members on journal and sleeve which halt inward movement of the journal and its rotation, such as an axial pin and hole, radial slot and key, and touching flat surfaces on the two members.
