Abstract
An axle suspension system is suited for a trailer including a trailer frame, an axle, and left and right wheels respectively connected on opposite ends of the axle. The axle suspension system includes a swing arm pivotably securable at one end to the trailer frame and connectable at an opposite end to the axle via a connector. The connector includes a bottom surface connected to the swing arm. A spring is connected at one end to the swing arm and is connectable at an opposite end to the trailer frame. A resilient pad may be secured between the bottom surface of the connector and the swing arm. In some arrangements, a track bar may be securable at one end to the axle and may be secured at an opposite end to the swing arm.
