An independent suspension is provided for a vehicle having a floor located between the vehicle's wheels. The independent suspension includes a light weight trailing arm pivotally attached at one end to the vehicle. An air brake actuator is affixed to the trailing arm below the floor of the vehicle. An axle supporting a wheel is cantilevered from the outboard edge of the trailing arm and an air spring is interposed between the trailing arm and the vehicle's body to oppose the force exerted by the axle. The trailing arm has a substantially planar body with a wall extending substantially around the periphery of the body. A thickened section of the body extends over an area of the lower surface of the planar body under the inner portion of the air spring bearing area. The construction of the trailing arm and the widely spaced frame attachment points make possible a suspension system having low unsprung mass but not requiring additional links to the frame for stability.

[ What is claimed is:] [1.]1. A suspension system on a vehicle comprising:(a) a trailing arm having a first end pivotally attachable to said vehicle at a pivot axis below a floor of said vehicle;(b) an axle affixed to said trailing arm at a first location spaced apart from said first end;(c) a ground engaging wheel supported on said axle for rotation about a center of rotation;(d) a spring having a first end vertically displaced below said center of rotation of said wheel and arranged for contact with said vehicle and a second end arranged to contact said trailing arm at a second location spaced apart from said first end, said spring urging said trailing arm to pivot away from said vehicle in opposition to a force exerted on said trailing arm by said axle;(e) a brake attached to said axle; and(f) a brake actuator, operatively connected to said brake, affixed to said trailing arm below said floor of said vehicle.
