Abstract
The invention relates to an apparatus and method for reducing the wobble tendency in an axle-mounted caster wheel assembly on a vehicle-mounted broom system. The caster wheel is mounted on an axle which is connected to a yoke. The yoke is attached to an upwardly extending column member. Movement of the column member is controlled by an adjustable braking mechanism located at the top of the column member. A rigidly-mounted tubular housing surrounds the column member and a threaded rod is mounted in the top of the column member. Tightening of a jam nut located on the top of the threaded rod exerts compressive force on an expandable bushing located between the column member and the tubular housing. Such force provides frictional contact with the column member, thus reducing the movement of the column member and yoke, thereby reducing the wobble of the caster wheel assembly.
