Abstract

A suspension system for a wheeled vehicle, particularly for off road use, the suspension system comprising a plurality of axle assemblies (26, 35, 44), each carrying wheels (27, 36, 48) at either end with a leaf spring suspension element (28, 37, 45) located between each end of each axle assembly and a chassis frame (20) of the vehicle, the axle assemblies (26, 35, 44) being connected to each leaf spring suspension element (27, 36, 48) by means of a connecting device (50) enabling pivotal movement of the spring suspension element relative to the associated axle assembly about an axis transverse to the axle assembly or generally parallel to the longitudinal direction of the vehicle thereby permitting relative vertical movement between the wheels at opposite ends of the axle assemblies without any substantial distortion or twisting of either the vehicle chassis or the spring elements themselves.

Claims13

Dependent claims

A vehicle suspension assembly comprising:

a chassis,
said chassis having a longitudinal chassis axis and defining a longitudinal chassis direction
an axle assembly disposed transversely to said longitudinal chassis direction,
a pair of wheels rotatably supported on said axle assembly,
a pair of laterally-spaced suspension leaf springs each connected at each end thereof to said chassis and disposed generally parallel to said longitudinal chassis direction,
a first connector means for connecting said axle assembly to each said suspension leaf spring intermediate the ends of said leaf springs and permitting pivotal movement between said axle assembly and each said suspension leaf spring about respective axes parallel to said longitudinal chassis direction,
a stabilizer member interconnected between said axle assembly and said chassis,
a second connector means for connecting said stabilizer member to said axle assembly and to said chassis at longitudinally-spaced locations and permitting pivotal movement relative to each about respective transverse axes parallel to said axle assembly,
said second connector means permitting pivotal movement between said stabilizer member and at least one said axle assembly and said chassis about an axis parallel to said longitudinal chassis axis, and
said second connector means permitting linear movement between said stabilizer member and at least one axle assembly and said chassis in said longitudinal chassis direction.
