ABSTRACT:
Disclosed is a load-setting device for railway cars which is installed on each such railway car and which sends an output to at least one of a power-running control unit and a brake control unit. The output is sent in the form of a load signal corresponding to an actual load applied on such railway car. The device comprises a preset-value generator which sets an initially preset pseudo-load signal corresponding to such railway car; a load-calculation circuit; and a load signal generator. The load calculation circuit is connected to receive the pseudo-load signal, at least one of power-running command and braking command as determined by acceleration-deceleration signals, an actual acceleration and deceleration signal on the basis of a railway car speed signal, and a slip-sliding detection signal. The load-calculation circuit modifies the pseudo-load signal in response to such at least one of such power running command and such brake command and such acceleration and deceleration signal. When such slip-sliding detection signal is input to the load-calculation circuit, the load-calculation circuit further modifies the pseudo-load signal in response to such slip-sliding detection signal and produces on its output an initial load signal. The load-signal generator stores the initial load signal and communicates same as an actual load signal. The actual load signal is usable by such at least one of such brake control unit and such power-running control unit to improve riding characteristics of such railway car.
