Patent ID: 7357213

Claim:
A starter with an electric oil pump for a hybrid vehicle, the hybrid vehicle comprising: an engine to generate a driving force by combustion of fuel; an auxiliary machine operated by the driving force generated during the operation of the engine; an integrated starter generator starting the engine using electric power charged when the engine is hot started, producing electric power using the driving force of the engine, and driving the auxiliary machine using the charged electric power when the engine stops idle operation; a belt to operate a pulley installed at each of a crank shaft of the engine, an output shaft of the auxiliary machine, and an output shaft of the integrated starter generator; a clutch installed on the crank shaft, and controlling power transmission between the crank shaft and the pulley installed at the crank shaft; an automatic transmission to shift and output a driving force generated from the engine according to driving conditions; a starter motor to generate a driving force by charged electricity when the engine is cold started, thus starting the engine; and an electric oil pump to supply hydraulic oil to the automatic transmission, wherein said starter motor comprises: a drive part rotated when operating power is applied; a selective engaging part having a pinion which is movably installed on a rotating shaft of the drive part, and engaging with a ring gear which is coupled to the crank shaft of the engine, during start; and an engagement drive part to operate the selective engaging part only when the engine is started, thus forcing the pinion to engage with the ring gear; and said electric oil pump shares a single rotating shaft with the starter motor.
