ABSTRACT:
The present invention relates to a novel trailer tongue assembly and a method of mounting a tongue frame on a trailer vehicle. A generally V-shaped tongue frame is pivotally coupled with the trailer vehicle at a point located below the trailer main frame and substantially co-planar with the supporting wheel and axle assembly. An elongated strut member is rigidly coupled with the tongue frame and extends toward the trailer vehicle along a vertical plane bisecting the two legs of the tongue frame. A leaf spring is coupled with the strut member and in turn is coupled with the trailer vehicle. The leaf spring is disposed so that its major plane of flexure will be perpendicular to the plane of the tongue frame.
