A NOVEL BOGIE WITH DIRECT SUSPENSION SYSTEM

The paper describes a novel bogie for direct suspension of the coach body on the wheelset journals via springs. As compared to the frame of conventional bogies, which must be dimensioned for transferring the load from the kingpin to the wheelset journals, the bogie with direct suspension system is provided only with a light guiding frame. A further reduction of mass and of all moments of inertia is achieved by supporting each wheel on either side. The construction of possible variants of the bogie with direct suspension system is explained, and the principal sub-assemblies are briefly described. The riding qualities, determined by way of a nonlinear time step simulation method, of the bogie with direct suspension system and of a conventional bogie are compared. It is shown that the bogie with direct suspension system is superior to the conventional bogie in respect of riding comfort, vertical track load, horizontal body acceleration, wheel/track wear and decay behaviour following a horizontal displacement due to a track irregularity.
