Abstract
A crank drive device for an internal combustion engine which comprises a crankshaft configured to be eccentrically connected to a connecting rod of a piston and to drive the drive shaft. The crankshaft is eccentrically connected to the camshaft and is rotatably supported with respect to the camshaft. An auxiliary motor which is configured to rotate the rotatable eccentric system.
Claims16
A crank drive device for an internal combustion engine comprising:
- a crankshaft;
- a camshaft;
- and
- a drive shaft for providing an output torque, wherein
- the crankshaft is configured to be eccentrically connected to a connecting rod of a piston of an internal combustion engine in a rotatably supported manner and to drive the drive shaft, the crankshaft and the camshaft are components of a rotatable eccentric system, in which the crankshaft is eccentrically connected to the camshaft and is rotatably supported with respect to the camshaft, and
- the crank drive device further has an auxiliary motor which is configured to rotate the rotatable eccentric system in a manner synchronized with a stroke cycle of the internal combustion engine.
A drive train for a vehicle comprising:
- an internal combustion engine which has at least a piston having a connecting rod;
- a crank drive device which has a crankshaft, a camshaft, and a drive shaft for providing an output torque, the crankshaft eccentrically connected to the connecting rod in a rotatably supported manner, and the crankshaft eccentrically connected to the camshaft;
- and
- an auxiliary motor configured to rotate the crankshaft and the camshaft, and the rotation synchronized with a stroke cycle of the internal combustion engine.
