Abstract
Abstract A mounting bracket (14,14') for attaching an axle housing (10) to a frame (16,16') includes a rigid column structure (26,26') attached to each of a front (22) and a rear side (24) of the axle housing (10) and having a longitudinal opening (30,30'), a plate (40,40') arranged above and below the column structures and axle housing, and threaded fasteners (50,52) which extend through the upper plate (40,40'), lower plate (40,40'), and frame (16,16'). The plates (40,40') are each attached only to the ends of the column structures (26,26') while the column structures (26,26') are attached to the front (22) and rear (24) sides of the axle housing (10) about a neutral axis (25). A continuous, endless weld joint (36,36') is deposited in a closed loop figure which is laterally bounded by a wall (34,34') of the column structure (26,26') defining the longitudinal opening (30,30') to join each column structure (26,26') to the adjacent axle housing side (22,24). Bolts (50) extending vertically through the top and bottom plates, the column structures, and the frame permit transmission of forces between the vehicle frame and the axle housing without overstressing the weld seams interconnecting the mounting bracket and axle housing.
