摘要： PROBLEM TO BE SOLVED: To provide a vehicle drive device provided with a hydraulic circuit capable of efficiently feeding the oil pressure from an accumulator to a clutch in a short time while maintaining the capacity of the accumulator to the required minimum value.
SOLUTION: In the hydraulic circuit 50 provided on a continuously variable transmission 30, the accumulator 58 is connected to an oil passage 75 for connecting a shift valve 55 to a forward movement C1 through a solenoid opening/closing valve 57, and a shut-off valve 60 for shutting off the oil passage 75 is provided on the oil passage 75 between a connection point 77a where an oil passage 77 connected to the accumulator 58 is connected and the shift valve 55. Further, the oil passage 77 is made in the communication state just before the oil pump 51 is driven by the solenoid opening/closing valve 57, whereas, it is made in the shutting off state just before the oil pump 51 is stopped. The oil passage 75 is made in the shutting off state by the shutting-off valve 60 when the oil pressure is fed from the accumulator 58 to the forward movement clutch C1.

摘要： PURPOSE:To secure a sufficient ground clearance under No.1 planetary gearing transmission mechanism even when applied to a small-sized car by mounting an accumulator on a valve body, and arranging oil-hydraulic servo over this accumulator. CONSTITUTION:One end 55 of a band 54 of a band brake B1 is fixed to a transmission case 158, wherein the band brake B generates selective engagement of a drum transmitting rotation of the input shaft of a planetary gearing transmission mechanism, and the other end is provided with a detent piece 57. When this detent piece 57 is pressed by a piston rod 58 of the oil-hydraulic servo B1 for band brake B1, the band 54 detains the rotation of coupling drum in its self-tying direction. An accumulator 71 is mounted directly on the lower valve body 77 of valve body 78 through a separator plate 79, and the oil path in this lower valve body 77 in communication to the accumulator 71, and the oil supplied to the hydraulic servo for clutch and brake is pressure regulated, The hydraulic servo B1 is located farther over the accumulator 71.
