ABSTRACT:
The towing characteristics of a trailer can be improved by utilizing a suspension system for the wheels of the trailer which tends to steer the trailer as it is towed behind a vehicle. Such a suspension system preferably includes an axle extending beneath the frame or body of the trailer, wheels on the ends of the axles and mounting structure such as springs connecting the ends of the axle to the body or frame. These mounting structures are constructed so as to cause the axle to move relative to the body of the frame so that the wheels tend to steer the trailer in response to the forces exerted on the mounting structures as the trailer is turned as it is being towed.
