摘要： A control apparatus for a dynamic power transmission apparatus is provided. The dynamic power transmission apparatus includes a differential mechanism, an electric generator, an electric motor, and a fluid coupling. The electric motor is disposed at a position apart from a transmission path along which a dynamic power of an engine is transmitted to a driving wheel. The fluid coupling is disposed between the electric motor and the transmission path. The control apparatus includes an electronic controller configured to restrict a charge of an electric storage apparatus with an electric power generated by the electric generator, depending on a state of the electric storage apparatus, and control the fluid coupling to differentially rotate and to drive the electric motor by the electric power such that a dynamic power loss is generated in the fluid coupling, when restricting the charge of the electric storage apparatus.

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.
