ABSTRACT:
The invention proposes a hybrid drive for a vehicle with a power train, which has a first electric machine (4), which is permanently connected to an input shaft (3) of the vehicle transmission (2) arranged between an internal combustion engine (1) and a vehicle transmission (2) with changeable gear ratio, and which can be operated as an engine or as a generator, and a hydraulic pump (5) for the vehicle transmission (2), in which at least one first shiftable clutch device (7) is arranged between the internal combustion engine (1) and the vehicle transmission (2), and in which the hydraulic pump (5) is torque-proof connected to the input shaft (3) of the vehicle transmission (2). A hybrid drive is also proposed, which comprises two electric machines, in which the hydraulic pump (5) is coupled via at least one element for force transfer to the input shaft (3) of the vehicle transmission (2).
