Document Type and Number:
Japanese Patent JPS6048608
Kind Code:
B2
Abstract:
A viscous fluid coupling device for use in automotive vehicles includes a rotatable input shaft driven by an engine and a rotatable output member driven by the input shaft via shearing force of viscous fluid thereby rotating a cooling fan in unison therewith. The output member is made of aluminum alloy whose coefficient of thermal expansion is larger than that of iron. The device includes a bearing set which is interposed between the output member and a stationary member made of iron. The bearing set is braked by the output member and the stationary member thereby decreasing the rotational speed of the fan when the ambient air temperature of the engine is below a predetermined value.
