Abstract
Traction mechanism drive for an internal combustion engine, having a crankshaft gear wheel, at least one gear wheel which is arranged on a driven shaft, a wrap-around means and an electric machine which can be actuated in order to reduce rotational non-uniformities, the electric machine (9, 10) having a rotor (12) which is arranged on the or a camshaft (1, 11) and interacts with an immobile stator (15).
Claims13
A traction mechanism drive for an internal combustion engine, comprising:
- a crankshaft gear wheel;
- at least one gear wheel which is arranged on a camshaft 1;
- a wrap-around means connecting the crankshaft gear wheel to the at least one gear wheel on the camshaft;
- and
- an electric machine, arranged on the camshaft, which is actuated in order to reduce rotational non-uniformities,
- wherein the electric machine has a flywheel rotor fixed to and extending radially outward from the camshaft and an immobile stator axially opposing and interacting with the flywheel rotor, the immobile stator positioned radially apart from the camshaft, and
- wherein the electric machine is operable as a motor or generator, depending on the type of rotational non-uniformities.
