A power transmission unit in which an inspection and tuning of an electric motor can be carried out easily. In the power transmission unit, a rotor of the electric motor is arranged between a first shaft of an input side and a second shaft of an output side, and in which the first shaft, the second shaft, and the rotor are integrally connected at least in a rotational direction. The first shaft is connected with the rotor, and the first shaft is also connected with the second shaft.

Power transmission device and method of assembling the same

A control device includes an arrangement for deriving an input torque input to a belt-type continuously variable transmission based on a control amount of a first actuator. The continuously variable transmission includes a first actuator that is provided on a one movable sheave side, that presses the one movable sheave toward one fixed sheave, and that can generate a belt pinching pressure on the one movable sheave side, and a second actuator and a torque cam that are provided on the other movable sheave side, that press the other movable sheave toward the other fixed sheave, and that can generate a belt pinching pressure on the other movable sheave side.

Device and method for controlling belt-type continuously variable transmission

A belt type continuously variable transmission is provided with two pulley shafts arranged in parallel a predetermined distance apart from each other, a movable sheave provided on each pulley shaft and being able to slide in an axial direction thereof, a fixed sheave arranged on each pulley shaft so as to face the moveable sheave, the fixed sheave and the movable sheave that face each another on each pulley shaft together forming a groove therebetween, and a belt wound around the grooves. At least one of the movable sheaves and a motor serving as a driving source for the moving sheave are integrally provided.

Belt type continuously variable transmission

A belt type continuously variable transmission in which a pulley shaft is supported by bearings provided at two positions that are apart from each other in an axial direction of the pulley shaft and a supply oil passage for supplying hydraulic fluid to a pulley hydraulic chamber includes a radial direction oil passage that is formed in the pulley shaft, the radial direction oil passage is formed on an outside of an area between the two positions. Also, one of the bearings is provided near the radial direction oil passage and on an outer surface side of a cylinder member whose inner surface side forms the pulley hydraulic chamber for a movable sheave that is fixed to the pulley shaft. With this structure, concentration of stress on the radial direction oil passage can be avoided, and therefore strength of the pulley shaft can be secured.

A power transmission system having an input member () and an output member () for transmitting power, and an oil pump () for discharging oil by a relative rotation between a first () and a second rotary members () which is driven by the power transmitted between the input member () and the output member (), characterized in that: the input member () and the first rotary member () are connected with each other in a power transmittable manner, and the output member () and the second rotary member () are connected with each other in a power transmittable manner; and characterized by comprising: a transmission member () for connecting the first and the second rotary members in a power transmittable manner; and a control valve () for controlling a power transmission state between the first and the second rotary members, by controlling a discharge condition of the oil pump ().

Power transmission system

A hybrid drive apparatus including an input shaft; a first motor and a second motor; a power distributing planetary gear; an intermediate transmission shaft; and a partition wall provided between a motor part including the first motor and the second motor and a transmission part including the transmission such that the intermediate shaft passes through the partition wall.

Hybrid drive apparatus

A shift device, which sends a command signal to an electric actuator for shifting a plurality of gear ranges of a transmission of a vehicle by the electric actuator. The gear ranges include a plurality of drive ranges and a parking range. A shift lever is arranged to move between a neutral position and a plurality of manipulation positions located about the neutral position. A restoration mechanism restores the shift lever to the neutral position. A first sensor electrically detects a manipulation performed to select one of the drive ranges. A second sensor electrically detects a manipulation performed to select the parking range. The first sensor detects toward which of the manipulation positions the shift lever is manipulated.

Shift device for vehicle

The transmission is constructed with a first ring gear and a third ring gear that are firmly connected. A second ring gear and a third carrier are also firmly connected. A second sun gear and a third sun gear are also firmly connected. An input shaft is connectable to a first carrier via a first clutch. The input shaft is connectable to a first sun gear via a second clutch. A third clutch is disposed between the first carrier and a second ring gear. The first carrier is connectable to the second ring gear and the third carrier via the third clutch. A first brake is provided between the first sun gear and a transmission case. A second brake is provided between the transmission case and the first ring gear as well as the third ring gear. A third brake and a one-way clutch are provided in parallel between the first carrier and the transmission case. A fourth brake is provided between the transmission case and the second sun gear as well as the third sun gear.

Automatic transmission

An automatic transmission includes a first rotating element provided by a sun gear of a second planetary gear set, a second rotating element provided by coupling carriers of the second planetary gear set and a third planetary gear set to each other, a third rotating element provided by coupling ring gears of the second and third planetary gear sets to each other, and a fourth rotating element provided by a sun gear of the third planetary gear set. The second and third planetary gear sets are combined with a first planetary gear set so that the automatic transmission can provide seven forward gear stages by changing a combination of two engaging elements, such as clutches and brakes, for coupling or stopping the corresponding rotating elements.

An automatic transmission includes a first rotating element provided by coupling a sun gear of a second planetary gear set and a carrier of a third planetary gear set to each other, a second rotating element provided by coupling a carrier of the second planetary gear set and a ring gear of the third planetary gear set to each other, a third rotating element provided by a ring gear of the second planetary gear set, and a fourth rotating element provided by a sun gear of the third planetary gear set. The first rotating element and the second rotating element are coupled to a case by first and second brakes, the fourth and first rotating elements are coupled to a ring gear of a first planetary gear set via first and second clutches, the second and first rotating elements are coupled to an input shaft via third and fourth clutches, and the third rotating element is integrally coupled to an output gear, so that the automatic transmission can provide eight forward gear stages by changing a combination of two of the clutches and brakes which are engaged to each other.

A switching valve is provided which operates hydraulic friction engaging elements in a combination to establish a fifth speed '5th' when in a first position, and in a combination to establish a third speed '3rd' when in a second position, when a first electromagnetic valve to a fifth electromagnetic valve fail so as to stop operating. As a result, in the event of failure while driving, the fifth speed &#x201c;5th&#x201d; is first established to enable the vehicle to continue running. Then, when the position of a manual valve is changed by an operation by the driver when the vehicle is stopped or the like, the switching valve shifts a transmission into the third speed &#x201c;3rd&#x201d;, which has a larger gear ratio than the fifth speed &#x201c;5th&#x201d;, to ensure the driving force required to take off again.
