A driving force transmitting device includes a case, an electric motor, and a gearbox. The electric motor includes an output shaft. The gearbox includes a spur gear that rotates coaxially with the output shaft. The case includes a partition wall, a first accommodating chamber accommodating the electric motor, and a second accommodating chamber that accommodates a second driven gear. The partition separates the first accommodating chamber and the second accommodating chamber from each other. The partition wall includes a connecting hole that connects the first accommodating chamber and the second accommodating chamber to each other. The connecting hole is located on one direction side in relation to the central axis of the output shaft. At least part of the connecting hole overlaps with the spur gear when viewed in a direction along the central axis.

Driving force transmitting device

A power transmission unit for a vehicle comprises: a motor arranged on an output side of an engine coaxially therewith in a housing adjacent to an outer face of the engine; an end cover arranged in the housing to cover an end portion of the motor to protect from the engine; a rotary shaft extending coaxially with the motor to be connected to an output shaft of the engine while penetrating through the end cover; and an engagement device disposed on an outer circumferential side of the rotary shaft between the motor and the engine to selectively restrict a rotation of the rotary shaft. A sub-cover to which the rotary shaft penetrates is attached to an end face of the end cover and a chamber is hermetically enclosed by the sub-cover, the end cover, and the rotary shaft. The engagement device is held in the housing.

Power transmission unit for vehicle

A drive system for a hybrid vehicle, the drive system includes an engine (), a rotary machine (MG), a differential unit (), and a transmission unit (). The rotary machine (MG) is arranged coaxially with the engine (). The differential unit () connects the engine () and the rotary machine (MG) to a drive wheel side. The differential unit () is arranged coaxially with the engine () and the rotary machine (MG). The differential unit () is arranged between the engine () and the rotary machine (MG). The transmission unit () changes rotation of the engine in speed and transmits the rotation to the differential unit (). The transmission unit () is arranged coaxially with the engine (), the rotary machine (MG) and the differential unit (). The rotary machine (MG) and the differential unit () are arranged between the transmission unit () and the engine ().

Drive system for hybrid vehicle

A vehicle includes: an engine; a first electric motor capable of inputting or outputting power; a power split mechanism including a sun gear, a ring gear and a planetary carrier rotatably revolvably supporting pinion gears meshing with the sun and ring gears. The planetary carrier, the sun gear and the ring gear are respectively coupled to an engine output shaft, a first electric motor rotary shaft and a drive wheel. The vehicle further includes a second electric motor capable of inputting or outputting power to or from the drive wheel; and a control device setting an engine operation range determined by a limit value of a rotation speed of the pinion gears. To increase durability of the pinion gears the limit value is higher at a high engine rotation and low vehicle speed side than at a low engine rotation and high vehicle speed side. Engine operation is controlled on the basis of the set engine operation range.

Vehicle and control method for vehicle

A vehicle drive device has an outer rotor type electric motor with a rotor disposed on an outer circumferential side of a stator including a first power transmission path coupling an inside of the rotor and drive wheels; and a second power transmission path coupling an outside of the rotor and the drive wheels, the first power transmission path and the second power transmission path having different gear ratios, one power transmission path of the first power transmission path and the second power transmission path being coupled to the drive wheels to make a gear change.

A sealing structure using a liquid gasket, having a liquid gasket interposed in the form of a thin film between mating surfaces of a first member and a second member, thereby preventing the movement of oil via the mating surfaces, the sealing structure, includes at oil-side end portions of the mating surfaces, a gasket lump portion that is formed of an excess of the thin-film liquid gasket squeezed out from the mating surfaces, and an oil-shielding portion that covers a boundary portion where the gasket lump portion and the first member come into contact, thereby preventing a flow of the oil from directly striking the boundary portion, and is provided on an oil-flow upstream side from the boundary portion.

Controlling a hybrid vehicle includes: reducing a rotation speed of a motor generator before a locking apparatus that locks the motor generator is switched from a disengaged condition to an engaged condition; starting to switch the locking apparatus to the engaged condition when the rotation speed decreases to a predetermined operation permission rotation speed; controlling the locking apparatus such that from the start of the switch to the engaged condition onward, the rotation speed decreases from the operation permission rotation speed to an engagement rotation speed with the motor generator in the engaged condition; and controlling the locking apparatus such that a decrease rate of the rotation speed when switching from the disengaged condition to the engaged condition in a low torque operation mode is higher than the decrease rate of the rotation speed when switching from the disengaged condition to the engaged condition in a high torque operation mode.

Control apparatus and control method for hybrid vehicle

A master cylinder body and a die for molding the master cylinder body which is unlikely worn out by a flow of the melt and improves the life duration of the die. A rib provided from a first outlet port projected from right external peripheral surface of the master cylinder body to an end portion of a front end portion via a second outlet port is formed deviated from a line connecting a central axial lines of the first and the second outlet ports. Likewise, a rib provided from the first outlet port formed on a left external peripheral surface of the master cylinder body to the end portion of the front end portion via the second outlet port is formed deviated from the line connecting the central axial lines of the first and the second outlet ports.
