In order to avoid the above problems, some locomotives employ a Combination Braking System (CBS), in which the brake oil paths of the front wheel and the rear wheel are mainly communicated with each other, and a delay valve is provided, so that when a driver presses a brake handle on the left side of a locomotive faucet, the hydraulic pressure in the brake oil paths can be distributed through the delay valve, so as to move the front wheel brake and the rear wheel brake.
The linkage brake system can effectively improve the stability of the locomotive during braking and deceleration and shorten the braking distance, however, if any brake oil pipe in the linkage brake system is damaged to generate oil leakage, the brake of the front wheel and the brake of the rear wheel on the locomotive are invalid, and the locomotive cannot be braked immediately when running on a road, so that safety is questioned.

As shown in fig. 1 and 2, the front brake assembly 20 includes a front brake handle 21, at least one front brake 22, a first front brake oil pipe 23, a second front brake oil pipe 24, and a first fluid, the first front brake oil pipe 23 is connected to the front brake handle 21 and communicated with the first pressurizing flow passage 15 of the flow divider 10, the second front brake oil pipe 24 is connected to the front brake 22 and communicated with the acting flow passage 17 of the flow divider 10, and the first fluid is filled in the first front brake oil pipe 23, the second front brake oil pipe 24, the first pressurizing flow passage 15, the first chamber 141, and the acting flow passage 17, wherein the first fluid is brake oil.
As shown in fig. 1 and 2, the rear brake assembly 30 includes a rear brake handle 31, a rear brake 32, a rear brake oil path 33 and a second fluid, the rear brake oil path 33 is connected to the rear brake handle 31 and the rear brake 32 and connected to the second pressurizing flow path 16 of the flow divider 10, and the second fluid is filled in the rear brake oil path 33, the second pressurizing flow path 16 and the second accommodating chamber 142, wherein the second fluid is brake oil.
The interlocking brake system with the failure prevention function is arranged in a locomotive, a front brake 22 of a front brake assembly 20 is arranged at the front wheel of the locomotive, and a rear brake 32 of a rear brake assembly 30 is arranged at the rear wheel of the locomotive.

As shown in fig. 2, the first pressurizing flow passage 15 of the flow divider 10 is in a communication state with the first chamber 141 in a normal state, and as shown in fig. 2 and 4, when the driver presses the front brake handle 21, the front brake handle 21 pressurizes the first fluid of the front brake assembly 20, so that the first fluid passes through the first chamber 141 of the flow divider 10 and drives the front brake 22 to move.
As shown in fig. 2 and 5, when the driver presses the rear brake handle 31 or steps on the foot brake pump 34, the rear brake handle 31 or the foot brake pump 34 pressurizes the second fluid of the rear brake assembly 30, and the second fluid, after being pressurized by the rear brake handle 31 or the foot brake pump 34, drives the rear brake 32 to move, and simultaneously flows into the second chamber 142 inside the flow divider 10 in a divided manner, and pushes the piston 12 inside the flow divider 10, so that the piston 12 pushes the first fluid inside the first chamber 141 to drive the front brake 22 to move, thereby achieving the effect of the linked movement of the front brake 22 and the rear brake 32.
As shown in fig. 2 and 5, when the piston 12 of the flow dividing valve 10 moves, the piston 12 cuts off the communication state between the first pressurizing flow passage 15 and the first accommodating chamber 141 to prevent the first fluid from being pushed by the piston 12 to generate a reverse flow, and when the driver releases the rear brake handle 31 or the foot brake pump 34, the resetting member 13 resets the piston 12 and restores the first pressurizing flow passage 15 and the first accommodating chamber 141 to the communication state.
Wherein, because the piston 12 in the flow dividing valve 10 can separate the first fluid from the second fluid and make the front brake assembly 20 and the rear brake assembly 30 independent, as shown in fig. 6, when there is a pipe breakage in the rear brake assembly 30 resulting in a second fluid leakage, the front brake assembly 20 can still move independently without being affected by the second fluid leakage of the rear brake assembly 30; similarly, as shown in fig. 7, when the front brake assembly 20 has a first fluid leakage due to a damaged pipe, the rear brake assembly 30 can also move independently without being affected by the first fluid leakage of the front brake assembly 20, thereby effectively preventing the brake system of the locomotive from failing and further improving the safety.
In summary, the linked braking system with the failure prevention function of the present invention not only can provide the driver with braking action on the front brake 22 and the rear brake 32 during braking to increase the stability of the locomotive during braking and deceleration, but also can separate the first fluid and the second fluid from the piston 12 in the flow dividing valve 10, and make the front brake assembly 20 and the rear brake assembly 30 independent from each other, thereby effectively avoiding the simultaneous failure of the front brake assembly 20 and the rear brake assembly 30, and further improving the safety.
