Abstract
A suspension system for wheeled vehicles, in particular, trailers and especially semi-trailers. The suspension system includes a platform with a top seat supported above an arcuate bottom saddle. The bottom saddle of the platform is designed for resting on an axle of a vehicle such that the top seat is positioned above the axle. Upper and lower pivot arms are provided each having a pair of opposite ends. A first end of each of the pivot arms is pivotally coupled to the platform. A hanger member has a top plate and a side brace downwardly extending from the top plate of the hanger member. The top plate of the hanger member has a proximal portion and a distal portion. The side brace of the hanger member is coupled to the proximal portion of the top plate. The top plate of the hanger member is positioned above the top seat of the platform. The top plate of the hanger member is designed for attachment to a support frame of a trailer. A second end of each of the pivot arms is pivotally coupled to the side brace. A biasing member is positioned between the top seat of the platform and the top plate of the hanger member. The biasing member biases the platform and the top plate of the hanger member away from one another in a generally vertical direction.
