Abstract

An electrified vehicle, comprising a chassis having a frame, a first tractive element, and a first suspension system coupled with the first tractive element and the chassis. The first suspension system may comprise a first knuckle coupled with the first tractive element, and a first strut-damper coupled with the first knuckle and the chassis, the first strut-damper extending between the chassis and the first knuckle. The first suspension system may also include a first control arm coupled with the first knuckle and the frame member, and a torsion bar coupled with the chassis at a first end of the torsion bar. The torsion bar may extend in a direction substantially parallel with the frame member, where the torsion bar may be configured to support a portion of a mass of the electrified vehicle in response to displacement of the first tractive element relative to the chassis.
