Abstract
A leaf spring assembly and a tandem suspension system of a vehicle includes a number of leaf springs secured together so as to form a central seat adapted to be mounted to a chassis of the vehicle. The leaf spring assembly also includes a first end portion adapted to be mounted to a first axle of the vehicle and a second end portion adapted to be mounted to a second axle of the vehicle. Each leaf spring features a central arcuate section and a pair of end sections, where a thickness of the leaf spring is at a maximum in the central arcuate section and tapers down in thickness towards the pair of end sections so that a constant stress results in the material of the leaf spring when the leaf spring assembly is used in the suspension system.
