Description
Technical field
The utility model relates to the how fast electric-control silicone oil fan clutch of one, belongs to a kind of fan clutch of car engine cooling system.
Background technique
At present electromagnetic fan clutch, realized the adhesive transmitting torque of adhesive dish and drive plate by shell fragment, be divided into two speed and three fast by rotating speed.Two fast electromagnetic fan clutch are the break-makes by control coil electric current, realize the high and low rotating speed of fan.Three-speed electromagnetic fan clutch is the break-make by controlling size coil current, realizes high, medium and low three rotating speeds of fan.It is when middling speed working state, permanent magnet and soft magnetic material produce foucault current by the permanent magnet on soft magnetic material on drive plate and fixed tray, drive fan turns, owing to can generate heat generation high temperature in cutting magnetic line process, when permanent magnet be in for a long time work under high temperature time, magnetic force will be decayed gradually, finally cause clutch to lose efficacy, therefore existence and stability be poor, the defect that life-span is short, in addition permanent magnet is rare earth material, price, and cost is high.
Above-mentioned two speed and three-speed electromagnetic fan clutch, when cooling medium is the condition of high temperature, electromagnetic coil is all energized, and adhesive dish is pull-in on drive plate, because High Rotation Speed produces larger inertial force during adhesive, friction between adhesive dish and drive plate produces spark, there is great noise and there is potential safety hazard, clutch is separated frequently, adhesive, accelerate the wearing and tearing of adhesive dish and drive plate, cause clutch to lose efficacy, affect working life.Moreover adopt electromagnetic coil energising working method due to it, structure must arrange permanent magnet, make the easier adsorption of dust of integral clutch, and the particularity of electromagnetic fan clutch structure, do not possess again dust-proof function, directly can affect the working life of clutch.
Existing silicon oil filled fan clutch has two kinds to control fast method, and a kind of is the change generation motion of temperature feeling ring along with coolant temperature, and mesh control chamber participates in the silicone oil amount of engagement, thus changes the rotating speed of fan, the temperature of reduction cooling medium.Another kind is that Engine ECU derives coolant temperature signal, makes electromagnetic coil energising and the power-off of clutch, and then the opening or closing of control valve, and drives the high and low rotation of fan, reduces coolant temperature.These two kinds of silicon oil clutchs, all also exist the state of cooling and the unmatched situation of the actual state of cooling of motor needs, make engine cooling medium too high or too low for temperature.Make motor obtain best operating temperature state, coolant temperature should control in the scope of 87 ~ 95 DEG C, and coolant temperature is too low, makes motor lose best working temperature environment, so increase friction, increase oil consumption, deterioration of emission.Coolant temperature is too high, and the while that cooling medium being vaporized, form high pressure (boiling), the cooling system of motor will be destroyed, except causing motor mass lesions, and also may the operation of stop vehicle.
Summary of the invention
The purpose of this utility model is to solve that the cost that prior art exists is high, noise is large, potential safety hazard is large, cooling requirement does not mate, poor stability and life-span short deficiency, there is provided a kind of smooth running, noise low, and temperature control is accurate, the how fast electric-control silicone oil fan clutch of energy-conserving and environment-protective.
The utility model is achieved through the following technical solutions:
