Abstract: A suspension system for the steering axle of a vehicle chassis provides anti-roll and frame stiffening properties. First and second leaf springs are provided aligned with longitudinal frame rails for a vehicle. An axle is attached to the middle portion of each of the first and second leaf springs with the axle being aligned transversely to the longitudinal frame rails. First and second shackle boxes depend from the longitudinal chassis frame rails aft of the axle and substantially adjacent the area of the longitudinal frame rails upon which the cab is supported. One end of each of the first and second leaf springs depends from one of the first and second shackle boxes. A bar is mounted transversely to the pair of longitudinal frame rails, connected between the first and second shackle boxes to resist vehicle roll and to stiffen the frame.

Abstract: A drive motor mounting module for a hybrid electric vehicle and the motor mounting module in combination with the hybrid electric vehicle. More specifically, the drive motor mounting module is comprised of a drive motor, a front motor mount support bracket, a chassis front support bracket, a chassis cross member, two rear motor mount brackets, two cross braces, two vertical channels and two motor module locating mounts. The entire module can be modularly assembled prior to installation to the vehicle chassis on a main assembly line. The mounting module engages the drive motor to the chassis by three point mountings.
