ある。 General torque converters are designed to achieve maximum efficiency in the speed ratio range of 0.6 to 0.8, and a planetary mechanism is installed between the turbine and the output shaft to achieve maximum efficiency even in the low speed ratio range. is also publicly known. However, all torque converters have one efficiency peak, so a torque converter that has its highest efficiency set in a relatively high speed ratio range has poor efficiency in a low speed ratio range; However, the disadvantage is that the efficiency decreases in the high speed ratio range.

となる。 However, when the first clutch 8 is turned on and the second clutch 10 is turned off, the stator 6 is fixed to the housing 1a, and the performance at this time is 0.6 of the speed ratio e as shown in FIG. 2a. The efficiency η has a peak at ~0.8. Next, when the first clutch 8 is turned off and the second clutch 10 is turned on, the stator 6 and the output shaft 4 are interlocked via the planetary mechanism 9, and the performance at this time is determined by the speed ratio as shown in Figure 2b. The efficiency η has a peak at 0.3 to 0.5 of e. Next, the first and second clutches 8, 1
When 0 is turned off, the stator 6 is in an idling state, and the performance at this time has a peak of efficiency η at a speed ratio e of 0.85 to 0.98, as shown in FIG. 2c.
