Abstract

The invention relates to a silicone oil clutch and a making method thereof, and belongs to the technical field of alloy materials. The silicone oil clutch mainly comprises, by mass, 7.5-9.5% of Si, 3.0-4.0% of Cu, 0.1-0.5% of Mn, 0.02-0.1% of Mg, 1.0-1.3% of Fe, 0.1-0.5% of Ni, 1.0-1.6% of Zn, 0.01-0.35% of Sn, 0.5% or less of other impurity elements, and the balance Al. The making method of the silicone oil clutch comprises the following steps: burdening above element components according to above mass percentages; preheating a crucible, coating the inner wall and the bottom of the crucible with a coating, adding above ingredients, fusing, removing slag, refining, and degassing; die-casting through semisolid die casting; and carrying out heat treatment of a die-casted casting to obtain the silicone oil clutch, wherein the heat treatment comprises solid solution treatment and aging treatment. The silicone oil clutch has the advantages of reasonable compatibility, simple technology, high mechanical properties and long service life.

Description

technical field [0001] The invention relates to a silicone oil clutch and a preparation method thereof, belonging to the technical field of aluminum alloy materials. Background technique [0002] The traditional silicone oil clutch uses silicone oil as a medium to transmit torque by utilizing the high viscosity of silicone oil. Using the temperature of the air behind the radiator, the disengagement and engagement of the fan clutch is automatically controlled by a temperature sensor. The working principle of the silicone oil fan clutch is: (1) When the engine is cold started or working with a small load, the temperature of the cooling water and the airflow passing through the radiator is not high, the oil inlet hole is closed by the valve plate, there is no silicone oil in the working chamber, and the clutch is in separation state. When the driving shaft rotates, only due to the friction between the sealing felt ring and the bearing, the fan and the housing are idling and s...
