摘要： A differential assembly and method of manufacturing such an assembly are provided. A method for manufacturing a differential assembly includes forming a first portion of a differential carrier; forming a second portion of the differential carrier; securing the first portion to the second portion to form the differential carrier; forming a differential housing; and securing the differential carrier to the differential housing to form a differential assembly. A sintering process may be used to form the first portion and second portion of the differential carrier, and the first and second portions may be secured together by a brazing process. The forming of the first and second portions of the differential carrier and the securing of the first and second portions to form a differential carrier may be achieved by a sinter-brazing process.

摘要： A powertrain includes a continuously variable transmission having a starting mechanism, a continuously variable unit (CVU), and a pair of planetary gear arrangements. The continuously variable transmission also includes a plurality of torque transmitting mechanisms which are selectively engageable in combinations of two to establish a reverse mode of operation between the starting mechanism and a transmission output shaft, a low direct mode of operation, an intermediate split mode of operation, and a high split mode of operation.

摘要： A device for reducing parasitic loss of a fluid pump is accomplished by connecting the power supply driveshaft to the drive pump element through a clutch element. The clutch element engages the drive pump element and frictionally engages the driveshaft so that at or above a predetermined fluid pressure, the clutch element releases the driveshaft so the driveshaft rotates within the clutch element thereby halting the pumping action of the pump. When the fluid pressure drops below a predetermined fluid pressure, the clutch element reengages the driveshaft to resume the pumping action.
