Transverse stabilizer for wheel axle suspension system

A suspension system for supporting first and second frame members on first and second sides of a vehicle chassis, said first frame member being positioned adjacent to a first end of an axle and said second frame member being positioned adjacent to a second end of said axle, said first frame member having a first hanger mounted thereto and said second frame member having a second hanger mounted thereto, a cross member mounted to said first hanger and to said second hanger, said suspension system comprising:

• a first fore-and-aft extending upper control arm pivotally mountable to said first hanger;
• a second fore-and-aft extending upper control arm pivotally mountable to said second hanger;
• a first fore-and-aft extending lower control arm pivotally mountable to said first hanger;
• a second fore-and-aft extending lower control arm pivotally mountable to said second hanger;
• and
• a stabilizer mounted to said first lower control arm and to said second lower control arm to form an H-frame member out of said first lower control arm, said second lower control arm and said stabilizer.

In combination, a vehicle frame and a suspension system supporting first and second frame members on first and second sides of a vehicle chassis, said first frame member being positioned adjacent to a first end of an axle and said second frame member being positioned adjacent to a second end of said axle, said first frame member having a first hanger mounted thereto and said second frame member having a second hanger mounted thereto, a cross member mounted to said first frame hanger and to said second frame hanger, said combination comprising:

• a first fore-and-aft extending upper control arm pivotally mounted to said first hanger;
• a second fore-and-aft extending upper control arm pivotally mounted to said second hanger;
• a first fore-and-aft extending lower control arm pivotally mounted to said first hanger and positioned below said first upper control arm;
• a second fore-and-aft extending lower control arm pivotally mounted to said second hanger and positioned below said second upper control arm;
• said first upper control arm extending generally parallel to said first lower control arm and said second upper control arm extending generally parallel to said second lower control arm;
• a transverse stabilizer mounted to an underside of said first lower control arm and to an underside of said second lower control arm to form an H-frame member out of said first lower control arm, said second lower control arm and said stabilizer;
• a first axle seat, said first upper and lower control arms being pivotally mounted to said first axle seat;
• a second axle seat, said second upper and lower control arms being pivotally mounted to said second axle seat;
• a first air spring mounted to said first frame member and to said first axle seat;
• a second air spring mounted to said second frame member and to said second axle seat;
• a first shock absorber mounted to said first frame member and to said first axle seat;
• and
• a second shock absorber mounted to said second frame member and to said second axle seat.
