<p>The invention relates to a method and appratus for improving the running qualities of a rail vehicle bogie (4) which is provided with a plurality of individual wheels (11, 12, 21, 22) whose travel motors are fed on a wheel-unit basis by means of two open-loop and closed-loop control devices (6, 8). According to the invention two wheel-unit speeds (n1, n2) are determined from the wheel speeds (n11, n12, n21, n22) obtained, from which wheel-unit speeds (n1, n2) an actual value ( DELTA n) of the wheel speed difference is formed, which actual value ( DELTA n) is adjusted by means of a manipulated variable ( DELTA m*) to a desired value ( DELTA n*) of the speed difference, as a result of which a hand throttle desired-value (m*) is increased and reduced by this manipulated variable ( DELTA m*). In this way, the wheel units (1, 2) are given a speed difference which is permanently adjusted and corresponds to the radius (r) of a bend, as a result of which the running behaviour in bends is significantly improved because the pitching condition is fulfilled. <IMAGE></p> |
