Brake cooling control system and mobile working machine

The invention relates to the technical field of vehicle brake control systems, provides a brake cooling control system and a mobile operation machine, and can be applied to fuel oil frameworks and new energy frameworks such as pure electric frameworks, extended-range electric frameworks, hybrid power frameworks, fuel cell electric frameworks and hydrogen engines. The liquid jet pump is used for jetting cooling liquid to the brake; and under the condition that the brake master pump executes the brake action, the brake master pump is used for providing driving gas for the liquid jet pump through the cooling switch in the open state, so that the liquid jet pump is driven by the driving gas to jet cooling liquid. The brake cooling control system serves as a brake cooling system, a liquid injection pump does not need to be manually controlled to spray cooling liquid, and cooling liquid spraying cooling can be conducted only through the brake action; in the driving process with large braking force requirement and f
