electric start engine

Abstract

The invention discloses an electrical starting engine. The electrical starting engine comprises an engine body and a magnetic motor fixed to the engine body. The magnetic motor comprises a stator module and a rotor module. The rotor module is in transmission connection with a starter of the engine through an overrun clutch. The overrun clutch is in limiting fit with the rotor module in the radial direction. It is guaranteed that the engine is compact in structure, and meanwhile, a rotor of the magnetic motor can be in stable single-direction transmission with the starting engine, and it is guaranteed that the engine is stable in starting performance; meanwhile, noise is reduced, efficient power transmission is guaranteed, and it is helpful to improve starting performance of the engine; meanwhile, an engine oil filtering cooler serves as a filtering device and cooling device for engine oil, the number of engine components is effectively reduced, and structural compactness of the engine is further improved; on the other hand, due to the constant temperature characteristic of engine cooling water, the viscosity-temperature property of the engine oil is effectively improved, and thus the lubrication effect of the engine components is improved; and it is guaranteed that the engine is small in loss and high in transmission efficiency in the starting and running processes.

Description

technical field [0001] The invention relates to a motor vehicle power system, in particular to an electric starter engine. Background technique [0002] The starting system of the engine includes the starter and the ignition system, and the ignition system includes a magneto that provides high voltage for the spark plug. The magneto is a small alternator that uses the power of the crankshaft of the engine to drive the magnet to generate an induced electromotive force. It is the ignition in the gasoline engine ignition system. Power supply, usually the magneto includes a stator and a rotor driven by the crankshaft. The stator is fixedly connected to the engine housing and is provided with an induction coil, and the rotor is provided with a magnet for changing the magnetic flux of the induction coil; at the same time, the rotor is also used as the flywheel of the crankshaft to cooperate with the crankshaft transmission , and the rotor is connected with an overrunning clutch tr...
