Problems solved by technology

However, in the conventional internal combustion engine, there is no passage for discharging oil and dust to the outside of the one-way clutch, so there is a problem that the oil and dust accumulated inside the one-way clutch cannot be discharged to the outside.

Abstract

The present invention is to provide an internal combustion engine for the purpose of discharging oil and dust accumulated in a one-way clutch with a simple configuration by the internal combustion engine, and enhancing cooling of a permanent magnet of a generator by means of the discharged oil. The provided internal combustion engine includes: a crankshaft (31); a generator (81), including a rotor (82) and a stator (89) fixed with a permanent magnet (87); a starter motor (60); a starter driven gear (63), The driving torque of the starter motor is transmitted to the starting driven gear, and the driving torque is transmitted to the rotor; the one-way clutch (65) only transmits the driving force from the starting driven gear to the rotor. A one-way clutch is interposed between the rotor and the starting driven gear in the radial direction. The rotor has a communication passage (86) providing communication between the interior of the one-way clutch and the exterior of the one-way clutch. The oil and dust accumulated in the one-way clutch are discharged with a simple structure, and the cooling of the permanent magnet of the generator is enhanced by the discharged oil.

Description

technical field [0001] The present invention relates to an invention of an internal combustion engine having a structure for discharging oil in a one-way clutch adjacent to a generator. Background technique [0002] In the existing internal combustion engine, in order to supply electric power required for charging a battery etc., a generator having a permanent magnet arranged in the inside of the rotor is provided, and a gear is provided adjacent to the generator, and power from a starter motor is transmitted to the gear. There has been a structure in which the power of the gear is transmitted to the crankshaft via the rotor, and only one of the gears rotationally driven from the starter motor to the rotor is performed by a one-way clutch interposed between the gear and the rotor in the radial direction. direction of power transmission. [0003] In such an internal combustion engine, oil or the like dispersed inside the internal combustion engine is supplied to the area be...
