An H-frame bogie comprises a leaf spring assembly 15 connected between wheel axles of the bogie. The leaf springs 15 have a non-linear spring characteristic resulting from identical cross-section and length of each leaf 17. The arrangement causes the wheel axes to radiate as the bogie negotiates a curve, thereby contributing to reduced wear and reduced possibility of derailment. The leaf spring 15 acts as a load equalizing beam. The connection between the bogie and the vehicle body is by a centre bearing assembly 6 which transfers horizontal forces and side bearing assemblies, each including a gear rack engaging with vehicle body rollers 10, which transfer vertical forces. <IMAGE> |
