CA 2108724
A beam-type axle suspension system particularly applicable to trailers and which is subject to torsional forces includes an elongated beam, a pneumatic bellows located on the beam, a hanger bracket located at one end of the beam, means for rigidly connecting the beam to the axle and a resilient pivot connection for resiliently connecting the beam to the hanger bracket wherein the beam includes an orifice through which the axle is slid or pressed and rigidly attached thereto, thereby preventing the axle from assuming a cross-sectional shape substantially different from its unstressed shape due to the torsional forces imposed on the axle. This beam- type axle suspension system also includes a resilient pivot connection for connecting the hanger bracket to the beam, thereby allowing the brake components to be attached to the beam instead of to the axle, and having the effect of eliminating stress risers on the axle due to weldinq the brake components to the axle. This is achieved by the combination of a pivot connection having a resilient bushing with different deflection in the beamwise and hangerwise directions and the rigid axle- to-beam connection which maintains a constant distance between the axle and the brake components.
