提出了双涡轮液力变矩器在高转速比时第一涡轮存在阻力矩,通过双涡轮液力变矩器原始特性曲线求得—涡轮阻力矩的计算方法,改变了双涡轮液力变矩器设计中将高转速比时—涡轮的阻力矩当作零的处理,从而得到转速和各种液力损失,使之设计计算更加符合实际和准确可靠。 The torque of the first turbine is presented when the twin turbine hydrodynamic torque converter is in the high speed ratio. The calculation method of the turbine resistance torque is obtained from the original characteristic curve of the twin turbine torque converter, and the torque variation of the twin turbine is changed In the design of the engine, the high speed ratio - the torque resistance of the turbine is treated as zero, and the speed and various hydraulic losses are obtained, so that the design calculation is more realistic, accurate and reliable.
