Embodiment Construction
[0043] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0044] Such as figure 1 As shown, a brake system for freight trains includes an air brake mechanism, a three-way valve 4 and a hydraulic damper brake mechanism. The air brake mechanism includes a 120-type air distribution valve 3 and a brake cylinder 5, The 120-type air distribution valve 3 is respectively connected to the train pipe 1 and the brake cylinder 5 through the first brake branch pipe 2. It is also connected to the auxiliary air cylinder 301 and the acceleration release air cylinder 302. The brake cylinder 5 transmits the force to the cargo train. The brake shoe and the inlet of the three-way valve 4 are connected to the air distribution valve 3 through the original pipeline leading to the brake cylinder, and the two outlets are respectively connected to the brake cylinder 5 and the brake mechanism of the hydraulic damper.
