A motive power stoppage guidance apparatus includes at least one of a display device configured to be disposed in a compartment of a vehicle, and a sound output device configured to output a sound in the compartment of the vehicle; and an indication control unit configured, when the vehicle is traveling in a state where a motive power stops, or when the likelihood is high in that the vehicle is traveling in the state where the motive power stops, to execute at least one of having the display device display at least one of that the motive power is in a stopped state, and a recommended operational method, and having the sound output device output an indication sound.

Motive power operation guidance apparatus

An automatic transmission () includes a planetary gear set (PS), first to third clutches (C-to C-), first to third brakes (B-to B-), and a counter gear () that outputs shifted rotation. The counter gear () is placed axially on one side of the planetary gear set (PS), and the second brake (B-) is placed axially on the opposite side from of the counter gear () from the planetary gear set (PS). The second brake (B-) that does not make higher speed rotation than other clutches and brakes can thus be separated from the planetary gear set (PS), and other clutches and brakes and the counter gear () are arranged near the planetary gear set (PS). Thus, members having a large thickness are reduced in length, whereby the automatic transmission is made compact and reduced in weight.

Automatic transmission

A vehicular automatic transmission includes three single pinion planetary gear sets and a plurality of engagement elements. A plurality of gears is selectively established by three of the plurality of engagement elements being engaged and three of the plurality of engagement elements being released. One of the plurality of engagement elements is a dedicated reverse engagement element that is engaged when a reverse gear is established and is released when a forward gear is established.

Vehicular automatic transmission

A hydraulic clutch including a clutch drum with an outer cylinder fitted with a plurality of clutch plates and a side wall; a clutch piston that defines together with the clutch drum an engagement oil chamber, and moves in an axial direction to press the clutch plates by hydraulic pressure supplied to the engagement oil chamber; and a cancel plate that defines together with the clutch piston a cancel oil chamber that cancels centrifugal hydraulic pressure. The side wall of the clutch drum is formed with a first oil passage that radially extends and is in communication with the engagement oil chamber, and a second oil passage that radially extends and is in communication with the cancel oil chamber. One of the first and second oil passages is at least partially included in a range of an axial width of the other of the first and second oil passages.

A lubricating oil supply device for an automatic transmission that includes a washer arranged inside the automatic transmission and regulating a movement of an input shaft in the automatic transmission in a shaft direction, wherein the washer includes: an oil reception section that receives lubricating oil scattered by a centrifugal force in a radial direction of the input shaft of the automatic transmission, and a guide path that guides the lubricating oil received by the oil reception section to a thrust surface at an end surface of the washer in the shaft direction.

Lubricating oil supply device for automatic transmission

A first element of a duplex planetary gear set is selectively coupled to an input shaft via a third clutch, or is selectively fixed via a first brake. A second element is selectively coupled, via a second clutch, to an intermediate shaft that is directly coupled to a speed-increasing element of a simplex planetary gear set which increases the rotational speed of the input shaft, or is selectively fixed via a second brake. A third element is directly coupled to an output shaft. A fourth element is selectively coupled to the input shaft via a first clutch. Therefore, by increasing the speed of the rotation of the input shaft by the simplex planetary gear set and transferring it to the duplex planetary gear set, it is possible to reduce the torques on individual components of an automatic transmission and therefore to reduce the sizes of the individual components and the capacities of the individual friction engagement elements.

An automatic transmission that includes two adjacent clutches. Two clutches each include a clutch drum, a piston that structures an operating oil chamber with a portion of the clutch drum used as a cylinder, a plurality of friction plates that engage with the clutch drum, a cancel oil chamber that is arranged on a back surface side of the piston and that cancels a centrifugal oil pressure acting on the operating oil chamber, and a return spring that is provided within the cancel oil chamber and that is structured between a cancel plate and a back surface of the piston and that biases the piston toward the operating oil chamber.

An automatic transmission that is structured such that the first clutch, the third clutch, and the fourth clutch are disposed in an axial direction more toward the speed-reduction planetary gear than the planetary gear unit; friction plates of the first clutch are disposed so as to be offset in the axial direction with respect to friction plates of the third clutch and friction plates of the fourth clutch; and the friction plates of the fourth clutch are disposed such that at least a portion thereof coincides in the axial direction with the friction plates of the third clutch on an inner peripheral side of the friction plates of the third clutch.

An automatic transmission that includes two clutches that are provided in mutually different positions in a radial direction while overlapping each other in an axial direction. The two clutches each include a clutch drum; a piston that structures a operating oil chamber while using a part of the clutch drum as a cylinder; a plurality of friction plates that engage the clutch drum; and a cancel oil chamber that is disposed on a back face side of the piston and that cancels a centrifugal hydraulic pressure acting on the operating oil chamber.

An automatic transmission that includes one clutch that includes a clutch drum; a piston that forms a hydraulic oil chamber using a part of the clutch drum as a cylinder; a plurality of friction plates that engage with the clutch drum; and a cancel oil chamber that is provided on a rear side of the piston and that cancels a centrifugal oil pressure that acts on the hydraulic oil chamber. Oil is supplied to the cancel oil chamber from a boss portion formed in the clutch drum on a radially inner side, and the oil is discharged from discharge holes formed in the boss portion to an outside of a hydraulic oil chamber side of the clutch drum.

An automatic transmission includes two clutches that are disposed such that they overlap in an axial direction and occupy different positions in a radial direction. Each of the two clutches includes a clutch drum, a piston that forms a working fluid chamber for which a portion of the clutch drum serves as a cylinder, a plurality of friction plates that engage the clutch drum, and a cancel oil chamber that is disposed on a rear face side of the piston and that cancels a centrifugal oil pressure that acts on the working fluid chamber.
