Power transmission device including a lubricated electromagnetic clutch

摘要

Oil is enclosed in a casing. A power transmitting section and an electromagnetic clutch are contained in the casing. The electromagnetic clutch has an electromagnet fixed to the casing. An oil sump is formed adjacent to the electromagnetic clutch. An oil gutter collects the splashed oil splashed by centrifugal force from the power transmitting section and the electromagnetic clutch and directs the collected oil into the oil sump. The power transmitting section has an oil path for introducing the oil from the oil sump, directing the oil to an area in the vicinity of the electromagnetic clutch, and supplying the oil to the electromagnetic clutch by means of the centrifugal force.
