Abstract: The manner in which a trailer "rides" and the "towability" of a trailer can both be improved by utilizing a wheel suspension system employing a separate suspension structure for each wheel of the trailer. Each of such suspension structures includes an elongated member serving as an axle. One of the ends of such a member is connected to the chassis of the trailer using a torsional energy absorption device while the other of the ends of the member carries a wheel of the trailer. The latter end of the member is connected to the chassis of the trailer through the use of a spring. Various adjustments are embodied within the suspension structure for use as reasonably required in connection with the trailer.
