From the viewpoint of energy conservation and transformation, this paper researches on the braking heat generation and brake temperature change characteristics during heavy-duty tractors brake, and a temperature-predicting model of brake drum is established. According to this model, firstly the entire vehicle kinetic energy is distributed thrice between front and rear axle, tire and road surface friction and sliding friction between hoof and drum, between linings and brake drum, and then the input heat of each drum brakes is figured out through the transformed kinetic energy. Secondly, each brake drum absorbs the heat and results in temperature rise, and dynamics temperature of brake drum is calculated considered cooling due to radiation, conduction, and convection.
