Abstract:
1. A vehicle chassis suspension for free rolling axles comprising: a) first and second trailing arms, each pivotally mounted to a vehicle frame through a pivot mount having a pivot axis that is aligned generally horizontally and perpendicularly to a vehicle chassis centerline, such trailing arms being connected to the pivot mount at a root end, the respective trailing arms each being displaced laterally from one another on a respective side of the vehicle chassis centerline; b) a resilient cushioning member or members connected between an underside of a vehicle chassis and a point on each trailing arm located at a position or positions remote from each of the trailing arm pivot axes, for the support of the vehicle frame and the filtering of shock energy transmitted from the trailing arm to the chassis; c) a pair of wheel axles respectively pivotally mounted to the first and second trailing arms at a point remote from the trailing arm pivot mount, pivot axes of the axles about the trailing arms being aligned longitudinally with the length of each respective trailing arm; d) one or more road wheels rotatably connected at each end of each axle, and e) a connecting member attached to both the first and second trailing arms whereby, upon either rotation of a trailing arm about its trailing arm pivot axis or rotation of a trailing arm in any direction other than that allowed by its trailing arm pivot axis, the connecting member communicates a resisting force to said rotating trailing arm originating from the other trailing arm.
