Abstract: A sub-assembly and corresponding assembly method for a vehicle suspension system, comprising a leaf spring (22); a pair of mountings (26, 28; 39) located at respective fore and aft ends of the leaf spring (22) and adapted to be attached to the respective ones of a pair of fore and aft brackets (27, 41) secured to the frame (23) of an associated vehicle; and complementary means (40, 43) associated with the leaf spring (22) and with at least one of the fore and aft mountings (26, 28; 39) and adapted to permit adjustment of the free assembly length of the spring (22) between its fore and aft mountings (26, 28; 39) during assembly of the sub-assembly. Similar adjusting complementary means (36, 46) for the leaf spring (22) may also be provided at or adjacent the centre of the leaf spring (22) for mounting a transverse vehicle axle (34) thereto.

Abstract: Vehicle suspension comprising a pair of leaf springs (1) located or locatable on respective opposed side of a vehicle chassis (3) and extending longitudinally thereof, and an anti-roll device (12) which is arranged to extend transversely of the vehicle chassis (3), and means (41, 42, 46) mounting opposed ends (22, 23) of the anti roll device (12) rigidly to respective ones of the pair of opposed leaf springs (1).
