Abstract

PURPOSE:To improve transmission efficiency of a fan clutch and to reduce the size and weight of the fan clutch by moving a clutch driven member along the driving thrust of a cooling fan to be coupled to clutch driving member. CONSTITUTION:When a driving member 3 is driven, a clutch driving member 9 is rotated integral therewith. When the temperature of cooling water of an engine becomes more than a set temperature, a temperature sensitive valve is opened so that a fluid flows through a circulation path 35 a circulation hole 36 a circulation path 27 a circulation hole 22 a gap portion 25 a connection hole 28 into space portion 27, which results in that a piston 15 is moved against a spring 34 in the opposite direction to the driving thrust 38 of a cooling fan 20. Whereupon, a clutch driven member 10 is moved in the same direction as the driving thrust 38 through a sleeve portion 16, a bearing 17 and a fan boss 13, so that the member 10 is coupled to the clutch driving member 9 so as to drive the cooling fan 20.

In conventional fan clutches, as disclosed in %Kaikaku Publication No. 51-82835, the direction in which the clutch closes is opposite to the direction of the driving thrust of the cooling 77, so the required spring pressure is insufficient to close the clutch. The pressure of the sum of the thrust force and the fan drive thrust force is required, and a large cylinder pressure-receiving area is also required to open the clutch. There was a drawback.
