US 6,484,596 B2 · Crankshaft starter-generator

Abstract

The invention relates to a crankshaft starter-generator for an internal combustion engine wherein the starter-generator is drive-coupled to a crankshaft of the internal combustion engine and serves both as the starter and the generator. A stator of the starter-generator is coupled with torsional strength to a motor block of the internal combustion engine. A rotor of the starter-generator is drive-coupled with the crankshaft of the internal combustion engine. A carrier is arranged coaxially with respect to the crankshaft and drive-coupled thereto. The rotor is drive-coupled to the carrier. The rotor and the carrier are arranged coaxially with respect to each other and are coupled to one another with torsional strength. Furthermore, the stator is arranged on the inside, and the rotor is arranged on the outside of the starter-generator.

Dependent claims

A crankshaft driven starter-generator, having internal and external sides, for mounting on a motor block of an internal combustion engine for performing as a starter and a generator, comprising:

a stator disposed on said internal side of said starter-generator, said stator being torsionally coupled to the motor block of the internal combustion engine;
a rotor disposed on said external side of said starter-generator and drive-coupled with the crankshaft;
a carrier coaxially disposed with respect to the crankshaft and drive-coupled to the crankshaft, wherein said carrier is coaxially arranged and torsionally coupled to said rotor;
at least one driver, wherein said rotor is supported independently of said carrier, and said rotor is torsionally coupled with said carrier by said at least one driver;
and
a rotational vibration damper for drive-coupling said rotor with said carrier, wherein said carrier is torsionally coupled with the crankshaft.
