<P>PROBLEM TO BE SOLVED: To give drive torque difference required between left and right wheels suppressing reduction in the total drive torque with simple constitution, in a left and right wheels drive system. <P>SOLUTION: This system includes first and second drive sources M1, M2, left and right drive wheels WL, WR, and a gear mechanism 2 interposed between both drive sources M1, M2 and the left and right drive wheels WL, WR. The gear mechanism 2 is a rotation mechanism having such four elements two flexibility that includes a linked opinion 20 in which a plurality of pinion gears are linked to one shaft, sun gears 24, 25 engaging with linked pinion gears 21, 22 of the linked pinion 20, a carrier 23 pivoting the linked pinion gear 20, and a ring gear 27 engaging with the pinion gear 22 of the linked pinion gear 20. Out of the four elements, when the first element rotates/fixes, one driving source is connected to the first element rotating in the same direction as other three elements rotates, and when the first element out of the other three elements rotates/fixes, the other drive source is connected to the second element rotating with the highest speed, and left and right wheels are connected to the remaining two elements. <P>COPYRIGHT: (C)2012,JPO&INPIT |
