英文摘要:
      Structure and operating principle of hydrodynamic retarder were briefed. Similarity theory was used for derivation of braking torque equation. Based on vehicle dynamics, on condition road slope was i, hydrodynamic retarder was installed on heavy vehicle gearbox output shaft, the hydrodynamic retarder long downhill constant speed brake equation was deduced. Integrating the hydrodynamic retarder braking torque equation with the calculation equation of constant speed brake equation,the brake deceleration speed equation of the hydrodynamic retarder on vehicle was given.It provides theoretical support for the development of hydrodynamic retarder constant speed braking function.
