Embodiment approach 1

[0053] figure 1 It is a figure which shows an example of the structure of the train brake apparatus concerning Embodiment 1 of this invention. figure 1 In the shown train braking device 100, as main components, there are a control unit 1, a load compensation valve 2, an AMV (Apply Magnet Valve (supply solenoid valve): supply valve) 20, an RMV (Release Magnet Valve (exhaust solenoid valve): Solenoid valve): exhaust valve) 21, relay valve 9, and brake cylinder 10 and constitute. Each component connected to the control unit 1 is shown bilaterally symmetrically around the load compensation valve 2 in the figure. This is because the first configuration unit connected to the control unit 1 controls the braking of the first bogie of each vehicle, and the second configuration unit controls the braking of the second bogie.

[0054] The control unit 1 reads the normal braking command 11 sent from the braking command unit. In addition, the control unit 1 reads the emergency braking co...

Abstract

To provide a train braking device including a controller that controls a brake cylinder pressure acting on a brake cylinder based on a service brake command or an emergency brake command, the train braking device includes a supply valve AMV 20 for supplying compressed air to the brake cylinder and an exhaust valve RMV 21 for adjusting a pressure of the supplied compressed air. The controller includes an electromagnetic-valve drive circuit 1a, which includes a first switch circuit that a first switch SW1 for slide control is connected in parallel to ends of a serially connected circuit of a first switch SW2 for emergency brake and a first switch SW3 for service brake control with its one end being connected to a circuit power supply P and the other end being connected to the supply valve AMV 20, and a second switch circuit that a second switch SW4 for slide control is connected in parallel to ends of a serially connected circuit of a second switch SW5 for emergency brake and a second switch SW6 for service brake control with its one end being connected to the first switch circuit and the other end being connected to the exhaust valve RMV 21.

Description

technical field [0001] The invention relates to a braking device for trains. Background technique [0002] In a train braking device with an air brake control unit, the air brake control unit generates a predetermined signal according to the normal braking command and the emergency braking command, and the solenoid valve generates an air signal corresponding to the predetermined signal, thereby obtaining Predetermined brake cylinder pressure. [0003] Conventionally, for example, in a train brake device disclosed in Patent Document 1 below, common circuits for service brake control and coast control are used in the air brake control unit. On the other hand, the circuit for emergency braking is configured independently of the circuits for normal braking control and coasting control. In addition, among the solenoid valves, although the common solenoid valves for normal braking control and coasting control are used, the solenoid valve for emergency braking has an independent ...
