Abstract
A wheeled work vehicle () comprises a forward chassis part () and a rearward chassis part () pivotally connected about a substantially vertically extending primary pivot axis () for steering thereof. A pair of forward ground engaging wheels () are carried on a forward suspension unit (), and a pair of rearward ground engaging wheels () are carried on a rearward suspension unit (). The forward suspension unit () is pivotally connected to the forward chassis part () by a pair of main forward transverse pivot shafts () pivotally coupled to the forward chassis part () by corresponding main forward pivot mountings (). The main forward transverse pivot shafts () defines a main forward transverse pivot axis () about which the forward suspension unit () is pivotal relative to the forward chassis part (). The forward suspension unit () comprises a pair of spaced apart trailing arms () which are joined by a torsion shaft () of tubular steel, which is rigidly connected to the trailing arms (). The torsion shaft () defines a torsional axis (), and permits limited upward and downward pivotal type torsional deflection of the trailing arms () relative to each other. The rearward suspension unit () is substantially similar to the forward suspension unit () and is coupled to the rearward chassis part () about a pair of main rearward transverse pivot shafts () in a similar manner as the forward suspension unit () is coupled to the forward chassis part ().
