Abstract
An engine-and-electric-machine assembly includes an engine and an electric machine, a crankshaft being provided in the engine, the crankshaft including a main body and an extension section that extends out to the exterior of the engine, the extension section forming a rotation shaft of the electric machine, a rotor of the electric machine being mounted on the extension section, and a transition section being provided between the main body of the crankshaft and the extension section, wherein the rotor of the electric machine is connected to the transition section via a flange structure. By connecting the rotor of the electric machine and the crankshaft of the engine by using a flange, instead of using a key connecting structure, the strength of the connection between the rotor and the crankshaft can be improved, and optimize the moment of inertia of the transmission structure between the rotor and the crankshaft.
