1355337 Railway bogies R HOOPER and B HOOPER 2 July 1971 [3 July 1970] 32333/70 Heading B7L A railway bogie, rotatable about a vertical axis, comprises a chassis frame 34 including two rigid side frames 21 and three or more axles, e.g. four 15, 16, 17, 18 rigidly mounted on said side frames by means of bearings located in housings 19, 26, 27 and 20 to prevent vertical movement of any wheel independently of the other wheels on the same side of the bogie, apart from that resulting from normal working clearances of the axle bearings. In the preferred embodiment four axles are provided, the two outer axles 17, 18 being supported by their bearing housings 19, 20 in the side frames in a permanently fixed vertical position and the bearing housings 26, 27 for the two inner axles 24, 25 being provided with screw jacks 28, 29 to enable the vertical position of those axles to be adjusted and secured in a position such that all the wheels will contact with equal loading, the running surface of the rail 47 on which the bogie runs. The side frames 21 are connected to the chassis frame 34 by means of springs 38, 39 to enable the side frames to negotiate undulations in the track. The side frames 21 are connected at their ends by resilient tie rods 32, 33. The load centre 48, i.e. the point where the load of the vehicle, to which the bogie is connected, acts, is centrally disposed as shown or is offset from the centre of the wheelbase by not more than 10% of said wheelbase in the opposite direction to the direction of travel.
