发明名称 VEHICLE DRIVE APPARATUS
摘要 An apparatus includes a case, a motor, a gear mechanism, a lubrication mechanism, and a cooling mechanism. The motor and the gear mechanism are housed in the case. The gear mechanism includes a specified gear and a first gear. A vertical lower section of the first gear is positioned above a surface of the oil. The lubrication mechanism lubricates the gear mechanism by the oil thrown up by the specified gear. The cooling mechanism includes an oil pump and a pipe. The oil pump and the pipe supply the oil reserved in the case to the motor. The pipe is located above the first gear. The pipe has a hole, and the oil discharged from the hole. The hole is positioned above the first gear. A normal line direction of the hole differs from a vertically downward direction. The first gear does not overlap the normal line direction.

主权项 1. A vehicle drive apparatus comprising: a case in which oil is reserved; an electric motor housed in the case; a gear mechanism housed in the case, and the gear mechanism including a specified gear and a first gear, a vertical lower section of the first gear positioned above a surface of the oil in a vertical direction; a lubrication mechanism configured to lubricate the gear mechanism by the oil thrown up by the specified gear; a cooling mechanism including an oil pump and a pipe, the cooling mechanism configured to pressure-feed the oil reserved in the case by the oil pump and supply the oil to the electric motor to cool the electric motor, and the pipe configured to feed the oil discharged from the oil pump to the electric motor, the pipe located above the first gear in the vertical direction, and the pipe having a hole, some of the oil flowing through the pipe being discharged from the hole, the hole being positioned above the first gear in the vertical direction, the hole being arranged at a position where a normal line direction of the hole differs from a vertically downward direction from the hole, and the first gear being arranged at a position that does not overlap the normal line direction of the hole.
