In a vehicle with a frame and ground-engaging wheels suspended therefrom by a suspension having, on each side of the vehicle, a bracket rigidly secured to the frame; a trailing arm pivotably mounted to the bracket and having two sets of openings, each set aligned transversely of the trailing arm; an air spring rigidly connected to and between the frame and the trailing arm; and a bushing extending between each set of aligned openings and positioned within the trailing arm. An axle is rigidly connected to each trailing arm by an axle bracket. Each axle bracket comprises a wrapper rigidly secured to the axle; two plates rigidly secured to the wrapper, each plate having two apertures aligned with the two sets of openings; a shock mounting bracket rigidly secured to one of the plates; and four gussets rigidly secured to and between the plates and the wrapper to add rigidity to the axle bracket to aid in withstanding torsional and lateral forces exerted thereon incidental to the operation of the vehicle. At least one of the four gussets is curved to resiliently yield in response to torsional forces between the wrapper and the connecting plate to which it is attached. Each axle bracket is secured to each trailing arm by two pins, each pin extends through each aligned set of apertures and openings and a bushing. A shock absorber is connected to and between each of the shock mounting brackets and the frame.

A vehicle suspension system for mounting ground-engaging wheels to a vehicle frame, the suspension system comprising at least two substantially rigid arms secured to opposite sides of the frame through substantially aligned pivot mounts; at least one wheel-carrying axle between said arms; and a bracket means securing said at least one axle to each of said arms; the improvement in each of said bracket means comprising: an axle plate means rigidly secured to said axle and having an elongated planar complementary surface at least partially wrapping around said axle; two spaced connecting plates secured transversely to said axle plate means and to one of said arms; and a bracing means comprising at least one curved gusset plate rigidly and angularly secured to and between said axle plate means and one of said connecting plates and structured to enhance torsional and shear resistance of said axle plate means and said connecting plates and to resiliently yield in response to torsional forces between said axle plate means and the one of said connecting plates to which it is attached.
