Abstract: A vehicle suspension friction control assembly includes vehicle suspension having at least two elements which are slidable with respect to each other in the fore-and-aft direction thereof. The assembly also includes a friction control device comprising a resiliently deformable member which is located between the suspension elements and means for limiting deformation of the deformable member to a predetermined degree in the fore-and-aft direction of the suspension elements. The suspension elements are slidable with respect to each other against friction when the deformable member has been deformed to the predetermined limited degree.

Abstract: A vehicle suspension system, comprising suspension means, anti-roll means capable of rotational movement due to deflection of the suspension means during straight axle static bounce motion thereof, and counteracting means arranged to act between said anti-roll means and the vehicle frame or chassis during straight axle static bounce motion of the suspension means, to at least partially counteract any consequential rotational movement of the anti-roll means, thereby applying a couple or moment to, and as a result, altering the deflection and rate of said suspension means.

Abstract: A suspension system for a vehicle wheel set, comprising first suspension means, second suspension means, and stabilizing means arranged generally transversely of the longitudinal axis of an associated vehicle and arranged to act in conjunction with at least one of said first and second suspension means, provide the vehicle with an anti-roll characteristic when operating under certain conditions. In a preferred embodiment, the first suspension means comprises a pair of leaf springs, and the second suspension means comprises a leaf spring, coil spring, hydraulic, pneumatic, or rubber (elastomeric) suspension arrangement, or any combination thereof, connected to an anti-roll bar or tube. Also provided is a composite stabilizing means in the form of an anti-roll bar or tube connected between a pair of leaf spring arms, preferably adjustable longitudinally thereof.
