Method for controlling an antislip-regulated friction brake system of a rail vehicle

摘要

A method for controlling an antislip-regulated friction brake system of a rail vehicle or rail vehicle train having a number of braked axles which subjects at least two selected axles to a braking pressure exceeding the braking pressure required for braking; measures at least one variable representing the maximum transmittable frictional force in each case between the wheels of the selected axles and the rail; prepares a list associating the selected axles with the respectively transmittable brake friction force; identifies at least one brake-slipping axle from the selected axles in which a brake slip exceeding a predetermined extent occurs; calculates lost braking work; identifies from the list at least one axle in which brake-slipping does not occur or occurs to a permissible extent; and applies the brakes on at least one axle.

1. A method for controlling an antislip-regulated friction brake system of a rail vehicle or of a rail vehicle train which is composed of a plurality of rail vehicles and which has a number of braked axles, the method comprising:
subjecting at least two selected axles of the number of braked axles during braking to a braking pressure which exceeds a braking pressure corresponding to a braking request for the braking; measuring at least one variable representing a maximum transmittable frictional force in each case between wheels of the selected axles and a rail; preparing a list of the selected axles assigned to respectively transmittable frictional force; identifying at least one axle with brake slip from the list of selected axles, at which axle, during braking, a brake slip which exceeds a predefined extent occurs and, therefore, antislip regulation is activated; calculating lost braking work at the identified at least one axle from the difference between a braking work which would have been carried out without activation of the antislip regulation and a braking work which is actually performed at this the identified at least one axle; identifying from the list of selected axles at least one axle without brake slip or with a permissible degree of brake slip for transmitting a greater frictional force than can be transmitted by the axle with brake slip; and applying the brakes at the at least one axle without brake slip or with a permissible degree of brake slip, in such a way that the braking work which is lost at the at least one axle with brake slip is at least partially compensated.
