Abstract

An integral transverse spring-axle combines the functions of both an axle and a suspension by locating the wheels laterally and longitudinally, in the manner of an axle, and allowing vertical displacements of the wheels, in the manner of a suspension. This is achieved with a leaf spring with a center portion, a pair of center leaves and at least one pair of side leaves both extending oppositely from the center portion. The outboard ends of the leaves attach to the wheel hub carriers/knuckles. The inboard center portion of the spring attaches to the chassis/body frame. The two opposite outboard ends of the spring-axle leaves can move independently of each other. The spring-axle can be of the steered or nonsteered type, and of the driven or non-driven type.
