The invention relates to an electromechanical brake applying device, especially for a rail vehicle brake, comprising a) an operating brake unit for producing a load-corrected and/or a skid-controlled brake force, b) an accumulation brake unit having an energy accumulator for storing and supplying energy for applying the brake, and c) an unlockable locking device for the energy accumulator. According to the invention, at least one control and monitoring device is provided for monitoring the brake function of the brake applying device. When the brake applying device is intact, a signal for keeping the locking device locked can be produced by said control and monitoring device, and in the event of safety braking and/or park braking, the operating brake unit can be activated in order to apply the brake.

The invention claimed is: 1. An electromechanical brake application device for a rail vehicle brake, the device comprising: a) a service-type brake unit for generating a load-corrected and/or slip-controlled braking power; b) an accumulator-type brake unit having an energy accumulator for storing and supplying energy for the application of the brake; c) an unlockable locking device for the energy accumulator; and d) at least one control and monitoring device for monitoring the braking function of the brake application device; the control and monitoring device, when the brake application device is intact, generates a signal for keeping the locking device locked and, also in the event of a safety and/or parking braking, the service-type braking unit is activated for applying the brake. 2. The electromechanical brake application device according to claim 1, wherein, when the brake application device is intact, the control and monitoring device constantly generates signals for keeping the locking device locked and overrides a safety and/or parking braking demand signal it generated for the unlocking of the locking device. 3. The electromechanical brake application device according to claim 1, wherein, when the brake application device is intact, the control and monitoring device prevents supplying of a safety and/or parking braking demand signal to the locking device by means of a switching device, and instead controls the signal for keeping the locking device locked. 4. The electromechanical brake application device according to claim 3, wherein the locking device has an electromagnetically operable construction, can be locked in an energized condition and can be unlocked when it is not energized, the safety braking demand signal being formed by a currentless condition which can be controlled by a safety loop of the rail vehicle. 5. The electromechanical brake application device according to claim 4, wherein the switching device contains at least one relay which, upon the safety braking demand signal and when the brake application device is intact, connects the locking device with a voltage source. 6. The electromechanical brake application device according to claim 1, wherein the locking device contains several locking elements, of which at least one locking element is sufficient for keeping the locking device locked, the signal for keeping the locking device locked being controllable from the control and monitoring device to this at least one locking element when the brake application device is intact. 7. The electromechanical brake application device according to claim 6, wherein the locking device is electromagnetically operable and, as the locking elements, contains several solenoid coils for generating magnetic forces locking or unlocking the locking device, the magnetic force of at least one solenoid coil controllable by the control and monitoring device being sufficient for keeping the locking device locked. 8. The electromechanical brake application device according to claim 1, wherein the control and monitoring device is integrated in a control device for the slip control and/or the load correction of the braking power generated by the service-type brake unit. 9. The electromechanical brake application device according to claim 8, wherein the braking power is constantly monitored with respect to the amount and the duration of action by the control and monitoring device. 10. The electromechanical brake application device according to claim 9, wherein the control and monitoring device is connected with a sensor for measuring physical quantities, from which the braking power generated by the service-type brake unit can be derived. 11. The electromechanical brake application device according to claim 10, wherein the output signal of the at least one sensor with the input signal for the control and monitoring device forms a criterion for the operability of the brake application device. 12. The electromechanical brake application device according to claim 11, including an additional redundant control and monitoring device controlling the locking device. 13. The electromechanical brake application device according to claim 1, wherein the locking device has an electromagnetically operable construction, can be locked in an energized condition and can be unlocked when it is not energized, the safety braking demand signal being formed by a currentless condition which can be controlled by a safety loop of the rail vehicle. 14. The electromechanical brake application device according to claim 3, wherein the switching device contains at least one relay which, upon the safety braking demand signal and when the brake application device is intact, connects the locking device with a voltage source.
