Abstract
The present invention provides a suspension system for a light duty trailer which includes a pair of modules. Each module is provided on an end of the axle and includes a spring member, a tower for connecting a front end of the spring member to an underside of the light duty trailer, an air spring connected between the underside of the light duty trailer and the spring member, and a limiting assembly for connecting a rear end of the spring member to the underside of the light duty trailer. In operation, if no bumps or ruts are encountered, the spring member remains generally horizontal relative to the underside of the light duty trailer. If a bump is encountered, the rear end of the spring member moves upwardly relative to the underside of the light duty trailer and the air spring compresses. If a rut is encountered, the rear end of the spring member moves downwardly relative to the underside of the light duty trailer and the air spring expands. The limiting assembly limits the amount of travel of the spring member.
