TRAIN BRAKE CONTROL SYSTEM FEATURING IMPROVED RAPID BRAKE APPLICATION CONTROL

摘要

The invention relates to a train brake control system which features improved rapid brake application control and in which a brake application request is transmitted by means of a train (1) composed of several units (2 to 5) by reducing a pressure in a main brake pipe (6; 69). Also disclosed is a driver's brake application device (11; 41) for controlling such a train brake system. The train brake system encompasses a driver's brake application device (11; 41) with a lever (12; 42) which can be mechanically moved into several control positions (43 to 48), including a rapid brake application position (43). Moving the lever (12; 42) in the rapid brake application position causes the main brake pipe (6; 69) to be bled in order to request rapid brake application. The driver's brake application device (11; 41) is embodied as an electromechanical actuator and comprises at least two separate electrical switching contacts (20, 21; 49, 50) which are coupled to the lever (12; 42) such that the at least two electrical switching contacts (20, 21; 49, 50) are opened when the lever (12; 42) is moved into the rapid brake application position, resulting in at least two separate electrical rapid brake application pipes (22, 23; 51, 52) being disconnected. Each of said electrical rapid brake application pipes (22, 23; 51, 52) encompasses one of the at least two switching contacts (20, 21; 49, 50) and is connected to one of at least two brake application groups (24, 25; 65, 66), each of which is fitted with an electropneumatic bleeding valve that operates according to a fail-safe principle, is connected to the main brake pipe (6; 69), and is moved into an open bleeding position when the electrical rapid brake application pipe (22, 23; 51, 52) connected to the respective brake application group (24, 25; 65, 66) is disconnected.
