ELECTRIC PNEUMATIC BRAKE SYSTEM OF RAIL TRANSPORT VEHICLE Russian patent published in 2009 - IPC B60T13/66 B60T15/36 

FIELD: transportation.

SUBSTANCE: invention is related to the field of railway transport, namely to braking equipment of railway transport vehicles. Electric pneumatic braking system comprises direct-acting electric pneumatic braking device and indirect-acting pneumatic braking device. Indirect-acting pneumatic breaking device comprises pressure controller, valve of pressure limitation, control valve and selection device. Pressure controller is arranged with the possibility to create initial control pressure of direct-acting brake depending on electric signal of required braking pressure of direct-acting brake. Valve for limitation of pressure is arranged with the possibility to limit initial control pressure of direct-acting brake to specified maximum initial controlling pressure of direct-acting brake. Control valve is arranged with the possibility to create initial control pressure of indirect-acting brake depending on pressure in air manifold of indirect-acting brake. Device of selection is arranged with the possibility of transfer effort from maximum initial controlling pressure of direct-acting brake and initial control pressure of indirect-acting brake that corresponds to this larger initial control pressure to gear with transmission ratio that varies depending on this condition of rail transport means loading through actuator, and the gear switches relay valve.

EFFECT: possibility to correct working brake load and to increase control range.
