Abstract

A bracket for fastening an axle housing to a suspension beam of a vehicle comprises a base with a pair of upwardly extending opposing walls. The base is configured to be secured to the lower portion of the axle housing and is provided with apertures for receiving fasteners attached to the suspension beam. Each of the opposing walls is configured such that they frictionally engage the lower channel portion of the lateral walls of the axle housing. Each opposing wall also has a upper surface suitable for welding to the lateral wall of the axle housing near the channel seam weld and an aperture through the wall for welding the wall to the fractionally engaged lateral wall. The top surface of each opposing wall is rounded off at each end to facilitate placement of a weld that extends down onto the lower portion of the axle housing. The welding aperture on each wall is preferably an elongate slot, especially one where the elongate dimension of the slot is parallel to the top surface and has rounded ends.

Dependent claims

In a drive axle assembly for a vehicle, a drive axle housing fastened to a suspension beam of the vehicle, the drive axle housing comprising an upper channel and a lower channel attached to each other by a seam weld such that the upper channel and lower channel constitute a pair of lateral walls with the seam weld running therealong, the drive axle housing being fastened to the suspension beam by an improved bracket, wherein the improved bracket comprises:

a base, upon which rests the lower channel of the drive axle housing, the base provided with apertures, each said aperture adapted for receiving a fastening member attached to the suspension beam;
a pair of opposing walls extending upwardly from the base, each said opposing wall frictionally engaging the lower channel of the drive axle housing;
each said opposing wall having a first end and a second end with an upper surface therebetween, each said upper surface welded to each lateral wall of the lower channel of the drive axle housing near the channel seam weld;
and
each said opposing wall having a window aperture through which the opposing wall is welded to the frictionally engaged lower channel.
