Example Embodiment
[0044] Embodiment 1.
[0045] figure 1 It is a figure which shows an example of the structure of the train brake device concerning Embodiment 1. figure 1 The train brake device 11 shown has the following structure: as main components, it has a speed sensor 1, a brake command unit 2, an air brake control unit 3, an electro-pneumatic switching valve 4, a relay valve 5, a pressure sensor 6, Brake cylinder 7, brake shoe 8, wheel 10, and master air cylinder 12.
[0046] The speed sensor 1 is installed on the front and rear bogies (four in total) of each vehicle, and can obtain the speed signal 1D of each wheel 10. The speed input unit 2 can obtain a speed signal 1D from the speed sensor 1a to the speed sensor 1d of each vehicle.
[0047] The brake command unit 2 can output a brake command 2D for obtaining a predetermined deceleration. The air brake control unit 3 can receive a brake command 2D sent from the brake command unit 2 and a load compensation signal sent from a load compensatio...
Example Embodiment
[0068] Implementation mode 2.
[0069] The train brake device 11 according to the second embodiment has a structure that can reduce the difference in the friction coefficient 23 due to the difference in the use time of the brake shoe 8 and can obtain stable deceleration. In addition, the structure of the train brake device 11 is the same as that in the first embodiment. figure 1 and figure 2 The structure shown is the same.
[0070] Here, the braking force can be obtained from the product of the brake cylinder pressure 5D and the friction coefficient 23 as described above. Here, the replacement period of the brake shoe 8 varies depending on the number of passengers and the use environment, etc. Generally, the longer the use time, the smaller the value of the friction coefficient 23 of the brake shoe 8 is. That is, the value of the friction coefficient 23 of the brake shoe 8 whose replacement time is early and the travel distance (usage time) is long has a lower value than that of...
