摘要： An integrated transmission includes a transmission housing having a first housing face through which the input shaft extends; a CVP housed within the housing; and a transmission assembly. The transmission assembly includes an input arrangement contained within the housing and having at least one input transmission component selectively coupling the engine power and the CVP power; a variator arrangement contained within the housing, configured to receive the engine and CVP power and to selectively transfer the engine power, CVP power, and a summing of engine and CVP power as variator output power; and a transmission gear arrangement contained within the transmission housing engaged with the variator arrangement and configured to provide a selective gear reduction for transmission to an output shaft that extends out of the transmission housing. The integrated transmission includes a power electronics apparatus arranged within or on the transmission housing and electrically coupled to the CVP.

摘要： A method for determining a bearing setting of a bearing in a shaft assembly, in which the shaft assembly includes a housing and a shaft rotatable with respect to the housing, with the bearing including a first bearing part coupled to the shaft and a second bearing part coupled to the housing, includes positioning a first portion of a measuring device in direct or indirect contact with the housing and a second portion of the measuring device in direct or indirect contact with the shaft. The method also includes measuring with the measuring device a parameter indicative of an amount of contact between the first bearing part and the second bearing part.

摘要： An electric machine includes a drive assembly and a casing. The drive assembly has a stator and a rotor rotatable about a drive axis relative to the stator. The casing contains the drive assembly and has coolant passages, the coolant passages defining a first inlet opening, a second inlet opening, a stator feed circuit, a rotor feed circuit, and an intersection providing fluid communication between the stator feed circuit and the rotor feed circuit. The coolant passages receive at least one coolant input through one or more of the first inlet opening and the second inlet opening to deliver coolant to the rotor through the rotor feed circuit and to the stator through the stator feed circuit.
