HYBRID DRIVE APPARATUS AND CONTROLLER FOR HYBRID DRIVE APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a hybrid drive apparatus that prevents unnecessary battery consumption and that allows a power transmission mechanism to be lubricated when a vehicle travels in a motor drive mode in which rotational driving of an internal combustion engine is stopped, and to provide a controller for the hybrid drive apparatus.

SOLUTION: Ball bearings 27 and 28 are fitted respectively to annular support units 25a and 25b of a case 25 such that inner peripheries 27i and 28i of outer races 27a and 28a of the ball bearings 27 and 28 are positioned more inward in the radial direction of a ring gear 3R, relative to the meshing portion 32 between inner teeth of the ring gear 3R and outer teeth of a pinion gear 3P. Thus, at the bottom of the ring gear 3R, an oil reservoir 33 is defined by the inner periphery of the ring gear 3R and a pair of the ball bearings 27 and 28.
