Abstract
Systems and methods for controlling movement of a mudflap hanger arm, to reliably return from a deflected position to a resting position, while providing improved manufacturability and reduced corrosion and wear through the use of guidance surfaces on a mounting plate and a frame seat that form the interface between the hanger arm and a vehicle frame. When the hanger arm pivots about an axis on one side of the mounting plate and frame seat, guidance surfaces on the opposite side are in contact or near-contact, preventing the mounting plate and frame seat from being laterally displaced or rotated with respect to each other. The improved mounting plate and frame seat can reduce or eliminate manufacturing operations such as welding, coating, etc., reducing the cost of the apparatus, while enhancing manufacturability and operation.
