Title:
HYBRID-VEHICULAR POWER TRANSMISSION APPARATUS
Document Type and Number:
Japanese Patent JP2018158630
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a hybrid-vehicular power transmission apparatus capable of improving the travel performance in an EV travel on motor drive force and suppressing a shaft length from increasing.SOLUTION: A power transmission apparatus for a hybrid vehicle Ve that includes an internal combustion engine 1, two motors 2, 3, a power distribution mechanism 4 for dividing output torque of the engine 1 into the first motor 2 and an output member 10 by a differential operation of three rotary elements 5, 6, 7, and a parking mechanism 18 for stopping rotation of the output member 10, further includes a lock mechanism 19 for stopping rotations of the first rotary elements 5, 6, 7. In a case where the parking mechanism 18 stops the rotation of the output member 10, the lock mechanism 19 disengages the lock of the first rotary elements 5, 6, 7, and locks the rotation of first rotary elements 5, 6, 7 in a case where the parking mechanism 18 disengages the lock of the output member 10.SELECTED DRAWING: Figure 2
