Hybrid drive system with modified Ravigneaux planetary gear

摘要

A Ravigneaux modified planetary gear hybrid drive system having an engine (100), a first motor (101), a second motor (102), power coupling means (200) and a drive shaft (300), the power coupling means (200) comprising: a first drive shaft (201) connected to the engine (100) via a first clutch (11); a second drive shaft (202) connected to the rotor of the first motor (101); a third drive shaft (203) connected to the rotor of the second motor (102); wherein the first drive shaft (201), the second drive shaft (202) and the third drive shaft (203) are in driving engagement with each other by a planetary gear having an inner sprocket (204), the inner spline ring (204) and the third drive shaft (203) are individually selectively in driving engagement with the drive shaft (300), the second drive shaft (202) being hollow and the first drive shaft (201) passing through the interior of the second drive shaft (202) and then engaging the planetary carrier (403). is connected so that a part of the planet carrier (403) between a small sun gear (401) and a large sun gear (402) of the planetary gear, characterized in that the planet carrier (403) connected to the shaft (201) in the axial direction between the two sun gears (401) and (402) is led out.
