摘要： A gear case of an in-wheel motor drive device houses first and second helical gears, has a first opening in its inner wall through which a motor main shaft passes, and has a second opening in its outer wall through which an axle passes. The in-wheel motor drive device further includes a first thrust bearing attached to the outer wall and supporting the first helical gear, and a second thrust bearing attached to the inner wall and supporting the second helical gear. The directions of helical teeth of the first and second helical gears are set so that when a motor vehicle travels forward, a thrust load directed outward in the vehicle width direction is applied to the first helical gear, and a thrust load directed toward the middle in the vehicle width direction is applied to the second helical gear.

摘要： A speed change device includes a power transfer shaft, a tubular shaft member, and a planetary gear mechanism that has a carrier. An in-shaft oil passage is formed in the power transfer shaft. A radially inner portion of the carrier and the tubular shaft member are splined to each other. An inside opening portion of a guide oil passage is formed in a non-spline portion of the radially inner portion. A target race member of a thrust bearing is disposed so as to abut against the carrier. The radially innermost position of the non-spline portion is on the radially outer side of the radially outermost position of a spline engagement portion. An oil receiving portion is formed by the tubular shaft member, the non-spline portion, and the target race member.

摘要： A control apparatus for a vehicular power transmitting system includes a drive mode setting portion configured to select a first reverse drive mode of the vehicle to be established with an engaging action of the first coupling element, and a required vehicle drive force determining portion configured to determine whether a degree of operation of an accelerator pedal of the vehicle during reverse driving of the vehicle is higher than a predetermined threshold value. The drive mode setting portion selects the first reverse drive mode when the required vehicle drive force determining portion has determined that the degree of operation of the accelerator pedal during the reverse driving of the vehicle is higher than the predetermined threshold value.

摘要： A vehicle drive unit to prevent a single phase lock of a motor as a prime mover to limit damage is provided. The drive unit includes: a first transmission route to deliver drive force of an engine to drive wheels; and a second transmission route to deliver drive force of a motor to the drive wheels. The second transmission route comprises an intermediate shaft that transmits the drive force of the motor to the first transmission route. A fluid coupling is disposed between the motor and the intermediate shaft. A lockup clutch is arranged parallel to the fluid coupling between the motor and the intermediate shaft.

摘要： A friction plate (11) includes a plate (1A) with a disc shape and a friction material (F1, F2) that is fixed to aside face (1a) of the plate (1A). The friction material (F1, F2) is disposed so that one or both of an inner peripheral side and an outer peripheral side is nonuniform in an inner and outer peripheral direction with respect to a circumferential direction around a center (CT1) of the plate (1A). Thus, there is an increase in the amount of lubrication oil that is fed to a surface of friction material segments (F1, F2) and there is an increase in a separation force in an axial direction between a friction plate (11) and a separator plate or an end plate.
