A vehicle suspension system having a pair of hanger brackets and a pair of beams. A first end of each beam is pivotally attached to each hanger bracket, and an axle is rigidly attached to the second end of each beam. A tri-functional bushing is positioned at each pivot to provide a horizontal spring rate different from the vertical spring rate. Each beam is formed with a top section and a bottom section which are joined along the longitudinal axis. Both the top section and bottom section are formed with axle recesses complementary related to a portion of the axle. Each axle recess is formed with a trailing edge positioned on either side of a arcuate section of the axle. In one embodiment, a rear plate extends downwardly from the top section adjacent the front of the axle and is welded thereto. In another embodiment, a half sleeve is positioned circumferentially around a front portion of the axle and is complementary related to the axle recesses of the top section and the bottom section. In this embodiment, a portion of the half sleeve adjacent the neutral axis is removed, and a plug weld is positioned therein to secure the half sleeve to the axle and a weld bead is provided circumferentially around the half sleeve adjacent the axle recesses formed in the top section and bottom section to secure the trailing beam to the half sleeve.

The wheel suspension link is formed of two identical longitudinal, sheet metal parts (1) whose U shanks (5,5') face each other. On one end of each part are annular collars (2), with their edges touching, while the major part of the parts are spaced from each other. Pressed into the two annular collars is a biasing bush (3). At the other end of the link, in the web area (4) of the U-shaped cross section of each part, are slots (9), through which passes a bearing bolt. ADVANTAGE - Low-cost mfr.

A trailing arm suspension includes a trailing arm body having an axle mount portion that is attached to an axle wrap The axle wrap includes at least one internal weld window to secure the axle wrap to an axle In one example, the internal weld window is positioned within an internal cavity defined by the trailing arm body and axle wrap includes an external weld window located external of the trailing arm body In one example, the trailing arm suspension includes a reinforcement bracket that is attached to both the trailing arm body and the axle wrap In one example, a spring pedestal includes a support plate at one end of trailing arm body and a side wall portion that extends downwardly from the support plate to be attached to the axle wrap In one example, the axle wrap includes a weld window having a V-shaped lower edge surface

Top mount trailing arm suspension

An axle unit with a vehicle axle a rigid axle body as an axle tube, with one radial arm each on both ends thereof. The radial arms are rigidly connected with the axle body, and one region of the arms forms the lower support for a spring element. The axle body and the two radial arms jointly are formed of two integral cast part halves that have been welded with one another along a partition line extending substantially in a horizontal plane.

Vehicle axle assembly

A suspension and axle assembly is provided having two identical stampings, each of which forms a portion of an axle and a portion of first and second suspension control arms that extend from the axle. The two stampings are coupled to one another along a continuous weld path. The assembly eliminates the connection points between the axle and control arms. The assembly also defines a pair of bores in which springs may be disposed at varying heights to lower the vehicle floor and reduce loads on the control arms, bushings, and other joints.

Suspension and axle assembly

The method enables certain components such as two half-shells (3), a hub (5) and flange (7) to be assembled for the purpose of forming a wheel axle terminal (1) and consists essentially of the following operations in succession: 
- positioning one of the half-shells (3) on the other so that their respective edges (11 and 13) and respective semicylindrical end portions (12) mate in order to form a cylindrical seat (4); 
- welding said half-shells (3) together along edges (11 and 13); 
- inserting said hub (5) into the cylindrical seat (4) and welding the axial ends of this latter to the seat (4) by circumferential butt welds; 
- positioning the flange (7) on an end portion (6) of the hub (5) which emerges from the seat (4), and welding the axial end of said portion (6) circumferentially by a butt weld to the flange (7).
