Abstract
A hybrid drive (1) for a vehicle has an internal combustion engine (2), an electric machine (26) and a double clutch transmission (5) with a hollow first input shaft (9) and a second input shaft (11) that penetrates the first input shaft (9). A hollow transmission shaft (15) is parallel to the input shafts (9, 11), and a drive torque can be applied to the first or second input shafts (9, 11) via the internal combustion engine (2) and/or the electric machine (26) via the double clutch (5) of the double clutch transmission (10). The electric machine (26) is outside the double clutch transmission (10), and an output shaft (25) of the electric machine (26) penetrates the hollow transmission shaft (15). As a result, a compact configuration is ensured.
Claims11
A hybrid drive for a vehicle having an internal combustion engine, an electric machine and a double clutch having plural switchable gear speeds, a double clutch transmission having a hollow first input shaft and a second input shaft that penetrates the first input shaft, and a hollow transmission shaft arranged parallel to the double clutch transmission so that a drive torque can be applied to the first input shaft or second input shaft by the internal combustion engine or the electric machine via the double clutch of the double clutch transmission, the electric machine being arranged outside the double clutch transmission, and an output shaft of the electric machine penetrating the hollow transmission shaft, and means for transmitting a rotational movement of the output shaft to the double clutch.
A hybrid drive for a vehicle having opposite front and rear ends, the hybrid drive comprising:
- an internal combustion engine and a double clutch in proximity to the rear end of the vehicle, the hybrid drive further comprising an electric machine, the double clutch having plural switchable gear speeds, a double clutch transmission having a hollow first input shaft and a second input shaft that penetrates the first input shaft, and a hollow transmission shaft arranged parallel to the double clutch transmission so that a drive torque can be applied to the first input shaft or second input shaft by the internal combustion engine or the electric machine via the double clutch of the double clutch transmission, the electric machine being arranged outside the double clutch transmission and at a position forward of the internal combustion engine and the double clutch for distributing weight forwardly on the vehicle and achieving efficient space utilization in proximity to the internal combustion engine, an output shaft of the electric machine penetrating the hollow transmission shaft, and means for transmitting a rotational movement of the output shaft to the double clutch.
