Abstract
For ensuring safety of heavy duty vehicles running on long downhill sections, a model was built for the application of engine brake and service brake combination based on test results. A model of brake temperature rise for heavy duty vehicles running on long downhill sections was also constructed. For different braking modes, gear positions, speed and downhill slopes, brake temperature rising to 250°C was used as the index. Then simulation of brake temperature rise and downhill distance was researched. Simulation results illustrate that the combined braking of low gear and high speed should be adopted for heavy duty vehicles running on long downhill sections.
Keywords: Brake temperature rise, engine brake, heavy duty vehicles, running on long downhill.
