Abstract
A torsion bushing includes a body portion defining a torsion rod-receiving bore, one or more helical flexion ribs defining at least a portion of the torsion rod-receiving bore, and a helical lubrication reservoir adjacent to the one or more helical flexion ribs. The torsion bushing may be included in a torsion busing assembly that further includes a bracket. The bracket may have a saddle to receive the torsion bushing, and one or more flanges for coupling the bracket to a frame. The torsion bushing may be included in a torsion rod assembly that further includes the bracket and a torsion rod.
