Problems solved by technology
The reason for this is the hitherto lower failure safety of electric brakes compared to pneumatic or hydraulic friction brakes, so that hitherto only the greatest possible braking safety could be achieved via friction brakes

Embodiment Construction
[0062] figure 1 A rail vehicle 10 in the form of a traction vehicle is shown in a highly schematic side view. The rail vehicle has an output shaft 12 and a drive shaft 14 , which are driven in traction mode by means of drive units 16 , 116 . The braking process of the rail vehicle 10 takes place by means of the drive units 16 , 116 , which here each have the function of an electric brake. For braking operations at low speeds, further braking devices 17 , 117 are provided, which are designed schematically in the drawing in the form of spring energy storage brakes (Federspeicherbremse). of the parking brake.
[0063] by means of figure 2 The control of the drive unit 16 as a component of the electric brake is explained in detail. The drive unit 16 has at least one drive motor 18 which can be designed as a three-phase motor. To supply the drive motor 18 with electrical power, the drive unit 16 also includes a power supply unit 20 , which is operatively connected to the driv...

The invention relates to a rail vehicle braking system having at least one electric first brake (24; 80) comprising a drive unit (16) and at least one brake adjustment unit (22; 82), the drive unit has at least one drive motor (18) and a power supply unit (20) for powering the drive motor (18) in the traction mode of the drive unit (16), the drive unit (16) The dynamic regulation unit has a corresponding said power supply unit (20) and at least one brake control unit (28, 30; 84), said brake control unit controls the corresponding said power supply unit in a first braking mode (20) to provide braking action. In order to optimize the handling of the cause of a loss of braking action, in particular to introduce backup measures, it is proposed that the rail vehicle braking system has at least one sensor unit (58; 86) and at least one connection with the first brake (24; 80) An associated first brake monitoring device (53; 190) independent of said brake regulating unit (22; 82), said sensor unit being arranged to detect At least one characteristic variable (B1) of the braking effect of the first braking mode, the first brake monitoring device is arranged to take into account the characteristic variable (B1) of the braking effect in the first monitoring mode in order to introduce Backup measures with respect to said brake (24; 80).
Description
technical field [0001] The invention relates to a rail vehicle braking system having at least one electrodynamic first brake comprising a drive unit and at least one brake adjustment unit, the drive unit having at least one drive motor and a power supply unit for powering the drive motor in the traction mode of the drive unit, the brake regulation unit having a corresponding power supply unit and at least one brake control unit, the brake control unit being in In the first braking mode, the corresponding power supply unit is controlled to provide a braking effect. Background technique [0002] Known are rail vehicles in which the braking force is generated by means of electric motors. The kinetic energy of the vehicle, which is converted regeneratively into electrical energy during braking of the motor, is converted into heat, for example via a braking resistor, or fed back into the railway power supply network or also into the mobile memory. [0003] In addition to electr...
