A HYBRID POWERTRAIN FOR A VEHICLE

The invention relates to a hybrid powertrain (1) for a vehicle. The powertrain comprises an internal combustion engine (2) having a crank shaft (3) rotatable about a geometric axis (4), an electric machine (5) and a transmission (6) having an input shaft (7) rotatable about the geometric axis (4), and a clutch (8) by which clutch the internal combustion engine and the transmission are selectively connectable to each other. A rotor (9) of the electric machine (5) is arranged on the crank shaft (3) for rotating together with the crank shaft about the geometric axis (4), and the clutch (8) is a dog clutch arranged for connecting and disconnecting the crank shaft (3) of the internal combustion engine and the input shaft (7) of the transmission to and from each other.
