A casing structure of a vehicular power transmitting device, includes: a casing; a breather plug; and a stationary removal preventive member, wherein the breather plug includes an attaching portion and a body portion, the body portion of the breather plug including an abutting section which abuts on the removal preventive member when the attaching portion of the breather plug is moved relative to the communication hole in a direction toward the outside atmosphere. The removal preventive member is positioned relative to the communication hole such that the attaching portion of the breather plug is located to keep the breather plug in communication with the communication hole when the abutting section of the body portion comes into abutting contact with the removal preventive member.

Casing structure of vehicular power transmitting device

A drive unit for vehicles that prevents a blow out of lubrication oil from a breather during splash lubrication is provided. A partition plate is disposed along a flat face of a ring gear to divide an inner space of the chamber into a first reservoir in which the ring gear is disposed, and a second reservoir to which the lubrication oil partially flows thereinto to return to an oil pan. The partition plate comprises a main body disposed between the flat face of the ring gear and an inner face of the chamber opposed thereto, and a bent portion formed on an upper end of the main body to guide the lubrication oil scattered upwardly by a rotation of the ring gear in a direction away from the breather.

Drive unit for vehicles

In setting of an oil temperature increasing process mode, the drive control technique of the invention starts an engine to actuate a mechanical oil pump that pressure feeds a flow of lubricating oil for lubricating the mechanical parts of a transmission and other relevant parts, actuates an electric oil pump that pressure feeds the flow of lubricating oil, and makes a brake Bincluded in the transmission in a semi-engagement state. A motor arranged adjacent to the transmission is then driven with lowered output efficiency. This arrangement effectively accelerates heat generation by the motor and ensures a quick temperature rise of the lubricating oil.

Driving device, motor vehicle equipped with driving device, and control methods of driving device and motor vehicle

A drive apparatus for a hybrid vehicle is provided with a first motor generator, a power splitting mechanism portion, and a second motor generator. The first motor generator functions mainly as a generator. The power splitting mechanism portion divides the power generated by the engine into power for the first motor generator and power for driven wheels. The second motor generator has an outside diameter that is smaller than the outside diameter of the first motor generator and is arranged on the side of the first motor generator opposite the engine. Further, a speed reducing mechanism portion which has an outside diameter smaller than the outside diameter of the second motor generator and which reduces the rotation speed of the second motor generator is provided on the side of the second motor generator opposite the engine.

Drive apparatus for hybrid vehicle

A planetary gear train includes a carrier having a first side plate, a second side plate disposed in parallel to the first side plate and pinions rotatably supported by the first and second side plates; and a ring member secured to an outer edge of the second side plate. The first side plate has a plurality of first convex portions whose edge portion form an outer edge and a plurality of first concave portions formed between adjacent first convex portions. The second side plate has a plurality of second convex portions whose edge portion form an outer edge and whose width in a peripheral direction is wider than the first convex portion, and a plurality of carrier bridges axially extended from a part between the plurality of second convex portions to the plurality of first concave portions and secured to the first concave portion.

Planetary gear train and driving unit having the same

An output of an internal combustion engine is transmitted to an output shaft by controlling a control motor to change a rotation speed output from the engine without speed steps via power distribution planetary gear. An output of a drive motor is input to the output shaft by changing the speed into two-step decelerated rotation by means of an automatic transmission. The transmission produces a desired torque by decelerating the speed by a large degree when a vehicle speed is low, and produces a desired number of revolutions by decelerating the speed by a small degree when the vehicle speed is high.

Hybrid drive system and vehicle equipped therewith

A drive unit for a vehicle structured so as to be able to attain an interrupting state of inertia of a drive motor under a predetermined condition. Therefore, the drive unit for a vehicle has a drive motor able to transmit driving force to a drive wheel, and an operation lever for selecting a shift range for switching the drive motor between drive and non-drive. Further, the drive unit for a vehicle has a control section having a shift position detector for detecting the shift range selected by the operation lever. The drive unit for a vehicle also has brakes for attaining a neutral state by interrupting the power transmission between the drive motor and the drive wheel when the selection of a parking range is detected by the shift position detector.

Drive unit for vehicle

A rotation of an input shaft is accelerated and transmitted to a drive shaft of an oil pump through gears. The oil pump is provided with a lubricant hole and part of the lubricant discharged from a discharge side oil chamber is supplied to a first sliding face of a radial bearing through the lubricant hole. By provision of a cutout portion in an oil sump and a first rib, part of the lubricant supplied from the input shaft to a bearing through a plurality of oil passages and the oil sump is supplied to a second sliding face which rotatably supports a thrust washer.

Lubricating mechanism of oil pump

The drive unit for a vehicle has an engine driving control element for driving a first motor on the basis of an engine driving signal, and driving a second motor so as to restrain a reaction force in a power distributing planetary gear due to the driving of the first motor in a state in which the stepped speed change gear connects the second motor and an output shaft by brakes. Further, the drive unit has an electrically operated oil pump for generating an operating oil pressure of the brakes, and also has a control section having an electrically operated oil pump operation control element for operating the electrically operated oil pump prior to the control of the engine driving control element on the basis of an engine starting signal outputted in a vehicle stopped state.
