ABSTRACT:
A simplified and economical flat bar torsion spring suspension assembly for trailers or other vehicles which extends between two wheels of the vehicle and which comprises a flat torsion bar for each wheel, each end of the torsion bar being received in a sliding fit in a corresponding socket. A socket at the end of the torsion bar adjacent to the corresponding wheel is rotatably mounted in the a housing which can double as frame of the trailer, and the socket at the other end of the torsion bar is held against rotation by the frame. A radial arm is attached to the rotatable socket and the corresponding wheel of the vehicle is mounted on the end of the radial arm. In the embodiments to be described, the housing for the suspension assembly can be used as the frame of the vehicle or merely a convenient package for ease of attachment and containment of a possibly cumbersome assembly.
