HYBRID DRIVE TRAIN OF A MOTOR VEHICLE

摘要

The invention relates to a hybrid drive train of a motor vehicle, comprising an internal combustion engine with a drive shaft, an electric machine (EM) that can be operated as a motor and as a generator, a stator (23) and a rotor (24), and a multistage planetary automatic transmission (1) with an input shaft (2) and an output shaft (3), wherein the drive shaft of the internal combustion engine is in drive connection with the input shaft (2) of the automatic transmission by way of a controllable separable coupling (C0) and the rotor (24) of the electric machine (EM) is in drive connection with the input shaft (2) by way of an input transmission stage (25). To create a hybrid drive train so described, which has the dimensions of a conventional drive train while maintaining as simple and space-saving a design as possible without any functional limitations, the electric machine (EM), the separable coupling (C0) and the input transmission stage (25) are combined with a module housing (22), an input element (5) and an output element (6) in coaxial arrangement in a pre-mounted hybrid module (4), wherein the input element (5) is connected rigidly to the drive shaft of the internal combustion engine and the output element (6) is connected rigidly to the input shaft (2) of the automatic transmission (1), and wherein the hybrid module (4) maintains the dimensions of a conventional hydrodynamic torque converter.
