This application relates to the field of cooling systems for trackless rubber-tired vehicles in coal mines, and discloses a cooling system for such vehicles, including an oil tank, a drive motor, a dual hydraulic pump, a brake accumulator circuit, and a fan hydraulic motor. The dual hydraulic pump consists of a coaxially linked dual front pump and a dual rear pump. The redesigned cooling system of this invention uses dual hydraulic pumps to drive the dual front pumps to ensure vehicle braking power and the dual rear pumps to ensure the engine receives constant cooling.
