Spud locking assembly for a pneumatically actuated clutch/brake

摘要

A spud assembly is provided for use in a pneumatically actuated brake, clutch or other friction assembly. The spud assembly includes a spud and a washer that are configured to reduce axial and rotational movement of the spud within the friction assembly. The spud includes a body portion that is centered about a first axis and extends through an aperture in a holding plate of the friction assembly. The body portion includes an outer wall that defines a pair of diametrically opposed flats. The flats engage a corresponding pair of flats in the washer which is fixed against rotation relative to the friction assembly holding plate. The spud also includes a holding member, such as a circular flange, that extends radially outwardly from the body portion of the spud. The holding member abuts one side of the holding plate to reduce axial movement of the spud.
