Fan clutch for vehicle

摘要

A fan clutch for a vehicle may include a shaft rotated by a drive force and having a first oil line formed in the shaft in a radial direction thereof, a rotor rotated in combination with the shaft, wherein the rotor includes an oil storage chamber formed in the rotor and the oil storage chamber communicates with the first oil line, a valve formed in an end of the oil storage chamber and being selectively opened, wherein the valve may be configured to allow oil stored in the oil storage chamber to flow to an outside of the rotor through the first oil line, and a housing formed to surround the rotor, and provided with a second oil line through which the oil that has flowed through the valve flows to the first oil line through an actuation chamber surrounding the rotor.

1. A fan clutch for a vehicle, comprising:
a shaft rotated by a drive force and having a first oil line formed in the shaft in a radial direction thereof; a rotor rotated in combination with the shaft, wherein the rotor includes an oil storage chamber formed in the rotor and the oil storage chamber communicates with the first oil line; a valve formed in a first end of the oil storage chamber and being selectively opened, wherein the valve is configured to allow oil stored in the oil storage chamber to flow to an outside of the rotor through the valve when the valve is opened, and the oil in the outside of the rotor is allowed to flow into the oil storage chamber through a first end of the first oil line when the valve is closed; and a housing formed to surround the rotor, and provided with a second oil line to communicate with the first end of the first oil line such that the oil that has flowed through the valve flows to the first oil line through an actuation chamber surrounding the rotor and formed in the housing, wherein the housing is rotatable by a viscosity resistance of the oil stored in the actuation chamber between the rotor and the housing while the oil stored in the oil storage chamber flows into the actuation chamber through the valve when the valve is opened.
