Title: HYBRID DRIVE TRAIN FOR A HYBRID-DRIVE MOTOR VEHICLE
Abstract:
The invention relates to a hybrid drive train for a hybrid-drive vehicle, comprising a transmission (1), more particularly a manual transmission, which can select different gear ratios by means of selector elements and which can be drivingly connected to an internal combustion engine (7) by means of an internal combustion engine-shaft (3), to an electrical machine (11) by means of an electrical-machine shaft (9), and to at least one vehicle axle (VA) by means of an output shaft (13). The internal combustion engine-shaft (3) and a power take-off shaft (17) that is drivingly connected to the output shaft (13) can be connected by means of radial gear sets, said sets being selectable by means of the selector elements and each set forming a gear plane (V1 to V4, E1, E2). According to the invention, the gear planes (V1 to V4, E1, E2) have a first and a second hybrid gear plane (E1, E2), each of which, in addition, can be drivingly connected to the electrical-machine shaft (9). The electrical machine (11) can be connected to the internal combustion engine (7) by means of the first hybrid gear plane (E1), thus forming a first load path (L1), and connected to the internal combustion engine (7) by means of the second hybrid gear plane (E2), thus forming a second load path (L2), while the power take-off shaft (17) that is drivingly connected to the output shaft (13) is simultaneously decoupled from the respective load path (L1, L2).
