Embodiment Construction
[0019] Some advantageous embodiments are described below with the aid of an exemplary braking device for a rail vehicle for providing a friction-coefficient-compensated brake control pressure for a pneumatic braking device of a rail vehicle.
[0020] figure 1 A schematic functional block diagram of the brake control apparatus according to the first embodiment is shown.
[0021] According to a first embodiment, the load pressure regulating, limiting or relay valve is designed such that it is possible, for example during rapid braking, independently of the load correction (L) of the brake pressure c by means of the corresponding load correction unit (L) 12 . In this case, the pressure characteristic curve is additionally changed (eg displaced) by increasing the volume by means of the force-increasing unit (V) 13 in order to compensate for changes in the coefficient of friction caused by changing the type of brake lining. For this purpose, a friction coefficient determination or...
