ABSTRACT:
A tire carrier assembly includes a rotation shaft and a housing have a bottom wall including a first aperture for receiving the rotation shaft. The housing also includes a sidewall extending upward from the bottom wall defining an interior space. The sidewall includes inner and outer surfaces. A sheave is disposed within the interior space of the housing and has a second aperture that receives the rotation shaft. The sheave also includes a gear member associated with it. Also included is a torque plate having a base, the base having opposing first and second surfaces and a third aperture formed therein. The third aperture has a gear portion formed around a periphery of the aperture. The torque plate also includes an arm portion projecting radially from the base. The gear portion of the torque plate is in operable engagement with the gear member of the sheave. An eccentric bushing having first and second opposing surfaces and an integrally formed bounding wall includes a fourth aperture receiving the rotation shaft. The first surface includes a cam formed thereon. The cam is positioned within the third aperture of the torque arm. A cable guide is positioned within the internal space of the housing and is located radially outboard relative to the sheave for positioning a cable about the sheave. The cable guide includes a lobe formed thereon for contacting a cable. A cover plate having a fifth aperture formed therein receives the rotation shaft. The cover plate is attached to the housing. The tire carrier assembly includes a frangible component that breaks upon the application of a predetermined force allowing the torque plate to freely rotate about the rotation shaft wherein the arm portion of the torque plate engages the inner surface of the sidewall of the housing allowing a controlled payout of cable wound about the sheave.
