Abstract

A vehicle suspension system includes left and right control arm assemblies each having a wheel mount structure, an upper control arm, and a lower control arm. Each control arm includes a first end configured to be pivotably connected to a frame structure of a vehicle and a second end rotatably connected to the wheel mount structure. The vehicle suspension system also includes a transverse leaf spring having an elongated body extending between the control arm assemblies, outer mounting brackets respectively connecting left and right ends of the elongated body to the left and right control arm assemblies, and one or more inner mounting brackets located between the outer mounting brackets. The transverse leaf spring is contoured such that a contoured portion of the elongated body deviates in a downward direction in order to extend below an electric drive system disposed within an internal space between rails of the frame structure.
