The invention provides a forced cooling system of a heavy-load axle. Two double-circuit oil coolers, totally four oil circuits, are used for circulating four main speed reducers, lubricating oil is circulated into the oil cooler, through engine water circulation, the high-temperature lubricating oil is cooled, and the cooled high-temperature lubricating oil returns to the shell of the speed reducer. According to the scheme, the problem that the main speed reducer generates heats in a long-time high-speed marching process of a heavy military wheel type off-road vehicle is solved, the reliability and the durability of the axle main speed reducer are greatly improved, and the safety of a vehicle transmission system during long-time marching is guaranteed. 本发明提供一种一种重载车桥的强制冷却系统，采用两个双回路油冷器共计四个油回路对四个主减速器进行循环，润滑油循环到油冷器中，通过发动机水循环对高温润滑油进行降温，被冷却后回到减速器壳内。该方案解决了重型军用轮式越野车辆长时间高速行军过程中主减速器发热问题，大大提高了车桥主减速器的可靠性和耐久性，保证了长时间行车的车辆传动系统安全。
