Abstract
A vehicle, having an engine (20) and a transmission (26), also includes an integrated assembly (24) between the engine (20) and transmission (26) which includes both a torque converter assembly (32) and an integrated starter-generator (ISG) assembly (36). The ISG assembly (36) is mounted between the torque converter assembly (32) and the transmission (26), with an ISG rotor (56) rotationally coupled to an impeller (42) through an assembly having compliance to allow for proper assembly and operation of the integrated assembly (24).
Claims20
An integrated assembly adapted to mount in a vehicle between an engine, having a crankshaft assembly extending therefrom, and a transmission, having a transmission input shaft and stator shaft extending therefrom, the integrated assembly comprising:
- a housing adapted to mount between the engine and the transmission;
- a torque converter assembly, located within the housing and adapted to mount adjacent to the engine, with the torque converter assembly including a cover adapted to rotatably couple to the crankshaft assembly, and an impeller rotationally coupled to the cover, and with the impeller including an impeller hub adapted to mount about the stator shaft;
- and
- a motor-generator, located within the housing adjacent to the impeller and adapted to mount between the torque converter assembly and the transmission, with the motor-generator having an ISG stator supported by the housing, an ISG rotor support mounted and rotatable relative to the housing, and with an ISG rotor mounted on the ISG rotor support adjacent to the ISG stator, and at least one flexible member connected between the ISG rotor support and the impeller such that the ISG rotor is rotationally coupled to the impeller.
An integrated assembly adapted to mount in a vehicle between an engine, having a crankshaft assembly extending therefrom, and a transmission, having a transmission input shaft and stator shaft extending therefrom, the integrated assembly comprising:
- a housing adapted to mount between the engine and the transmission;
- a torque converter assembly, located within the housing and adapted to mount adjacent to the engine, with the torque converter assembly including a cover adapted to rotatably couple to the crankshaft assembly, and an impeller rotationally coupled to the cover, and with the impeller including an impeller hub adapted to mount about the stator shaft;
- a bearing mounted between the impeller hub and the housing;
- and
- a motor-generator, located within the housing adjacent to the impeller and adapted to mount between the torque converter assembly and the transmission, with the motor-generator having an ISG stator supported by the housing, an ISG rotor support riding on a bearing mounted to the housing, and with an ISG rotor mounted on the ISG rotor support adjacent to the ISG stator, and a set of compliant pin assemblies connected between the ISG rotor support and the impeller such that the ISG rotor is rotationally coupled to the impeller.
