Abstract
A trailer suspension system has an axle, a pair of frame hanger brackets, dual trailing arm beams, and a spring. The pair of frame hanger brackets are mounted spaced apart underneath the trailer. The dual trailing arm beams are connected rigidly to the axle at one end and resiliently connected to a respective one of the frame hanger brackets with a pivot means bushing at the other end. The spring intermediate the trailing arm beam and the trailer to support the trailer load. Wherein, the axle connection center is the center of the patch that connects the axle to the longitudinal trailing arm beam, thereby reducing the stress on the axle as well as increasing the stability of the suspension system.
