Abstract
A front wheel suspension for a front wheel drive vehicle incorporating dual shock absorber struts arranged in tandem. Each fore and aft strut has its cylindrical casing lower end pivotally connected to an associated one of a lower control arm bifurcated leg portion for rotational movement about a longitudinal extending strut lower pivot axis. Each strut casing upper end is pivotally connected by a pintle pin for rotating movement about a longitudinal extending strut upper pivot axis to the inboard end of a swingable upper control arm. The lower control arm leg portions have their inboard ends pivotally connected to a sub-frame engine cradle for rotational movement about an axis parallel to the strut upper and lower pivot axes. An intermediate portion of a drive half shaft assembly is positioned in the space between the fore and aft struts. A transverse leaf spring has each outboard end supported on an associated lower control arm. Intermediate portions of the leaf spring are supported on the sub-frame cradle such that the front wheel suspension is mounted solely on the sub-frame cradle.
