    摘要: This invention relates to bogies for railway rolling stock. In particular it relates to suspension arrangements for such bogies wherein the frame is mounted on a spring suspension arrangement. In one embodiment the spring suspension arrangement comprises two groups of springs on either side of a wheel axle (11), each group comprising an inner spring (14) and two outer fore and aft springs (15, 16). In another arrangement there are two lower springs (14) on either side of a wheel axle (11) and at least one upper spring (21) above the axle. The arrangements described provide better lateral and longitudinal stiffness and shear characteristics which, reduce hunting and wheel wear. They also enable the axles to accommodate increased loads.
