| Abstract: | Aiming to the problems of heavy duty truck driving on long and steep downgrades with high frequency accidents, in this paper, based on the purpose of reducing the work load of brake in serv-ice, continuous braking of heavy duty truck driving on long and steep downgrades is studied with the mathematical model of exhaust brake and eddy current retarder which is established by combing theory and experiment. The relationship between continuous braking and engine speed is obtained, laying a foundation for studying of brake drum temperature rise to solve the problem of thermal recession of the brake. |
