Abstract: A pivot assembly for a tandem suspension is provided which includes a balancer and an elastomeric assembly operable to allow the balancer to rotate about a vehicle chassis. In addition, an elastomeric assembly for a suspension system is provided which includes an elastomeric element provided with a slot for allowing a deformation in response to a tension load imparted by a balancer, and a groove for preventing bulging in response to a compression load imparted by the balancer. A balancer for a vehicle suspension is also provided which includes first and second plates, an open area formed between the plates, an engaging member provided within the open area and first and second pins which define an axis of rotation about which the balancer is rotatable. A kit for the pivot assembly is also provided.

Abstract: A tandem suspension for connecting a vehicle chassis to front and rear steerable axles is provided. The tandem suspension includes, on each side of the vehicle, a front leaf spring linking the chassis and the front axle, a rear leaf spring linking the chassis and the rear axle, an equalizer assembly mounted to the chassis for equalizing the front and rear axles, a front air spring disposed between the chassis and the front axle, a rear air spring disposed between the chassis and the rear axle, and a pneumatic control system pneumatically linked to the front and rear air springs for supplying pressurised gas thereto and operable to unload one of the front and rear air springs. A method of installing a tandem suspension in a vehicle having a first steerable axle and a front leaf spring is also provided.
