Abstract:
1. A vehicle suspension arrangement for a vehicle having a chassis rail and a transverse axle arranged substantially orthogonal to the chassis rail, the vehicle suspension arrangement comprising: an air-assisted primary spring having a resilience characteristic responsive to air pressure, a first portion for coupling to a chassis of the vehicle at a primary coupling, and a second portion for coupling to the transverse axle; and a secondary leaf spring having a plan view longitudinal configuration, a first end for pivotally coupling to the chassis of the vehicle at a secondary pivot coupling, and a second end for coupling to the transverse axle; wherein the entire length of the plan view longitudinal configuration of said secondary leaf spring extends in a single substantially linear direction that is arranged at a predetermined angular displacement with respect to the chassis rail, the angular displacement of the secondary leaf spring relative to the chassis rail being from about 5 degrees to about 10 degrees.
