Dynamic component 20 with the rear brake assemblies 30 independently, therefore, as shown in fig. 6, brake assemblies 30 have pipeline breakage when described after
And when leading to the situation of second fluid leakage, the preceding brake assemblies 20 remain to self-movement without by the rear brake assemblies 30
Second fluid leakage influence；Similarly, as shown in fig. 7, causing first-class when the preceding brake assemblies 20 have pipeline breakage
Body leakage situation when, it is described after brake assemblies 30 also can self-movement without by the preceding brake assemblies 20 first fluid infiltration
The influence of leakage can effectively avoid the brake system of locomotive from failing, and then improve safety.
In conclusion the present invention has the coupling brake system of anti-invalidation functions in addition to that can provide driver in brake
When, while the front brake 22 being allowed to carry out brake with rear brake 32, to increase stability when locomotive brake slows down,
And the piston 12 in the flow divider 10 can separate the first fluid and the second fluid, and make the preceding brake assemblies 20 and the rear system
Dynamic component 30 independently, can effectively avoid the preceding brake assemblies 20 from failing simultaneously with the rear brake assemblies 30, Jin Erti
High security.
