Claims10
A suspension trailing arm for suspending a heavy vehicle chassis from a beam-type axle, the suspension trailing arm comprising:
- a chassis mounting formation;
- a first cast or forged component including a first portion of an axle locating formation, and an arm portion being an integral casting or forging with the axle locating formation and extending between the first portion of the axle locating formation and the chassis mounting formation;
- and
- a second component comprising a second portion of the axle locating formation and a bracket for mounting a spring;
- wherein the first portion and the second portion of the axle locating formation mate together to fully encircle a portion of a beam-type axle;
- wherein a thickness of the cast or forged suspension trailing arm above the axle locating formation is less than 50 mm.
