ELECTRICALLY-PNEUMATIC DEVICE FOR CONTROLLING BRAKING SYSTEM OF RAILWAY VEHICLE Russian patent published in 2020 - IPC B60T13/66 

FIELD: electricity.

SUBSTANCE: electropneumatic device (1) comprises vehicle load signal generating sensor (2), measuring devices (IUU, EFRS), intended for supply of measured pneumatic pressure depending on load signal, and first and second brake control units (BCU1, EPCA1; BCU2, EPCA2), connected to measuring devices (IUU, EFRS) and containing corresponding acceleration valves (RV), which supply through their outputs corresponding brake pressure, changed depending on said measured pneumatic pressure, to corresponding braking drives (BC1, BC2) connected to wheels of corresponding axle (A1, A2) or corresponding vehicle trolley. Measuring devices (ECU, ECS) comprise electropneumatic actuator assembly (EDPA) arranged between pneumatic pressure supply devices (AR1, AR2; R1, R2; SV) and input of acceleration valve drive (d), as well as an electronic measuring control unit, providing control of said drive unit assembly depending on said load signal in order to preliminary change in pressure at input of drive (d) of said acceleration valves. Pneumatic pressure feeders comprise first and second pressure tanks (AR1, AR2) connected to the input of acceleration valve (RV) of the first and second brake control units (EPCA1; BCU2, EPCA2) respectively by means of corresponding shutoff valves (R1, R2).

EFFECT: invention allows providing functionality of braking system of vehicle bogie axis.
