The invention discloses a rear axle speed reduction cooling device. The rear axle speed reduction cooling device comprises a transmission roller, a rear axle speed reducer, a rear axle rod, a power generator, a braking servo switch and two fans. A driving roller linked with the transmission roller is arranged in the rear axle speed reducer. The tail end of the driving shaft stretches to the position behind the rear axle speed reducer to be connected with a rotary shaft of the power generator. An electric engagement and disengagement device is arranged between the tail end of the driving shaft and the rotary shaft of the power generator. The braking servo switch is connected with the electric engagement and disengagement device. The two fans are linearly connected with the power generator. In this way, according to the rear axle speed reduction cooling device, in the braking process, the electric engagement and disengagement device is powered on to work, the tail end of the driving shaft and the rotary shaft of the power generator are in rigid connection for rotary power generation, the fans are powered on to blow air to air-cool a braking device, the braking performance is improved, the braking device can be cooled, the heat stability of the braking device is improved, and service life is prolonged.
