A railway bogie is disclosed with wheels of high effective conicity and supported on the wheels through pads with low yaw constraint so that they are self-steering. Cross-members connecting diagonally opposed wheels interconnect yawing movements of the wheelset in opposite senses to counteract the tendency to hunt. Wheels on the same side of the bogie are connected by links pivoted on a lever pivoted on the bogie frame at one end and on the bearings of the wheelsets at the other end. This interconnection inhibits the bogies frame from moving longitudinally when braking or traction forces are present and ensures that yawing movements of the frame are effectively transmitted through the wheelsets and then to the wheel/rail contact area. |
