<p>Railway vehicle suspensions are provided in which the vehicle body is supported directly on truck mounted spring devices for transverse tilting movement about a longitudinal central axis of the body. Transversely acting power means are provided to hold the body against such transverse tilting movements during tangent track operation and to cause such transverse tilting movements, or banking, when rounding curves. In one embodiment of the invention the spring devices at each side are supported from the truck frame by transversely swingable links whose projections intersect at the tilt axis and the vehicle body is supported by horizontal bearings on the spring devices. The truck frame mounts a transversely acting power device which is connected to the spring devices. In another embodiment, the spring devices are carried directly by the truck framing, and support the body by spherical section bearings whose common center is at the intersection of the truck swivel axis and the tilt axis. A transversely acting motor mounted on the body is connected at its ends to the spring devices to produce lateral and consequent tilting movements of the body on the spring devices.</p> |
