摘要： A vehicle drive-force transmitting apparatus including: a casing provided with an oil supply hole through which an oil is to be supplied to a lubrication-required element. The casing is provided with a first guide portion and a second guide portion. The first guide portion defines a first path that is configured to guide the oil to flow from a diagonally upper side of the oil supply hole, toward the oil supply hole. The second guide portion defines a second path that is configured to separate the oil flowing along the first path, into a part of the oil and another part of the oil in an intermediate portion of the first path and to cause the part of the oil to join with the another part the oil in a position located right above the oil supply hole.

摘要： A vehicle drive-force transmitting apparatus including: a casing provided with an oil supply hole; a pump for pumping out an oil stored in the casing; and a pipe for delivering the oil pumped out by the pump, such that the oil discharged from the pipe is supplied to the oil supply hole. The oil is to be discharged from the pipe collides with an oil collision portion which is a portion of the casing and which is located on an upper side of the oil supply hole. The casing includes a guide portion and a block portion. The guide portion is located on a lower side of the oil collision portion, so as to guide the oil discharged from the pipe toward the oil supply hole. The block portion is located to surround the oil collision portion, so as to block the oil splashing from the oil collision portion.

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.

摘要： A ball bearing on one rotary shaft, out of a first rotary shaft and a second rotary shaft, on which a rotation member corresponding to a larger value of a ratio out of values of ratios of a rotation speed of a first rotation member and a rotation speed of a second rotation member relative to a rotation speed of a third rotation member is arranged does not include an inner race. Thereby, a ball PCD can be reduced while securing durability of a ball bearing on the one rotary shaft, and dragging loss between balls of the ball bearing and the inner race can be reduced. Since the ball bearing integrally configured with the rotary shaft is arranged on the one rotary shaft, reducing dragging loss of the ball bearing relatively largely reduces motive power loss on the third rotary shaft due to dragging loss of the ball bearing.

摘要： A control device for a vehicle includes an electronic control unit. The electronic control unit is configured to set a share ratio of driving force of the first electric motor and the second electric motor. The electronic control unit is configured to set the share ratio of the driving force such that when the temperature of a pinion gear in a planetary gear mechanism is higher than a specified temperature, the share ratio of the driving force of the first electric motor is lower than the share ratio when the temperature is lower than the specified temperature.
