<p><P>PROBLEM TO BE SOLVED: To provide a motor power transmitting device capable of distributing and outputting even the power from a high-speed high power motor to two shafts and actively controlling the distribution of torque. <P>SOLUTION: Motor/generator MG1, MG2 are coaxially arranged in a center of a case 1 as a composite current two layer motor, first and second planetary gear groups G1, G2 are coaxially arranged on the right side of the motor/generator, and a third planetary gear group G3 is also coaxially arranged on the left side thereof respectively. A first ring gear R1 and a second carrier C2 are connected with each other, and a first carrier C1 and a second ring gear R2 are connected with each other to constitute one differential device 5 with G1, G2 and the other differential device 6 with G3. One output shaft Out1 is connected to R2 to connect between C2 and a third sun gear S, and MG1 is connected to the first sun gear S1, while MG2 is connected to the second sun gear S2. The other output shaft Out2 is connected to a third ring gear R3 to fix a third ring gear R3. The power of MG1, MG2 is distributed and output to Out1, Out2 while being decelerated with both differential devices 5, 6, and the power of MG1, MG2 can be controlled to control a torque distribution ratio to Out1 and Out2. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
