Power transmitting system for a hybrid motor vehicle

摘要

The system has an engine (1), and a planetary gear (3). The planetary gear (3) has a sun gear (3a), a carrier (3b) rotatably supporting a plurality of pinions (3d) each of which engages with the sun gear (3a), a ring gear (3c) engaging with the pinions (3d). A first motor (2) is connected to an output shaft (1a) of the engine (1) and the sun gear (3a) of the planetary gear (3). The first motor (2) is capable of using as a driving source and as a power generator. A second motor (4) is connected to the ring gear (3c). The second motor (4) is also capable of using as a driving source and as a power generator. An automatic transmission (5) is connected between the carrier of the planetary gear (3b) and an axle (8) of a hybrid motor vehicle.
