Description
Technical field
The utility model belongs to engine blower control technique field, relates in particular to a kind of electromagnetic fan clutch control gear.
Background technique
Three-speed electromagnetic fan clutch---be the one of electrical control electric fan clutch, have idle running, low speed and at full speed 3 kinds of rotation speeds of the fan.Can carry out speed control according to the different operating modes of motor, reach noise reduction, fuel-efficient effect.Three-speed electromagnetic fan clutch can be according to the needs of engine-cooling system; automatically adjust engine cooling fan working speed; existing three-speed electromagnetic fan clutch is conventionally realized and is selected gear shift by ECU control mode, exists in actual use the high and frequent gear shift of energy consumption to cause the situation of clutch accelerated wear test.
Traditional electromagnetic fan clutch is controlled the rotating speed of fan according to engine water temperature, its concrete working principle can be with reference to following:
A, engine water temperature are during lower than setting value (adjustable), and clutch no electric circuit, relies on front end pivot friction to drive fan running, and rotation speed of the fan is (100～200) r/min;
When b, engine water temperature reach 2 fast setting value (adjustable), control to the medium and small coil power supply of clutch, now rotation speed of the fan is (40%～60%) of main shaft input speed;
When c, engine water temperature reach 3 fast setting value (adjustable), large and small coil power supply in clutch is given in control simultaneously, and now rotation speed of the fan equals main shaft input speed.
Magnetic clutch adhesive produces magnetic attraction by electromagnetic coil energising, and when separation, by adhesive dish, coil component spring resilience separately separates in power-off, therefore magnetic clutch adhesive with separate quite rapidly in 0.5s.The temperature control strategy of electromagnetic constant-temperature fan, is divided into rising edge and trailing edge.
At present, on intercity passenger vehicle, the magnetic clutch fans that use, generally travel with speed of a motor vehicle 90km/h more on expressway, the operating mode of often overtaking other vehicles in running process.20 DEG C of ambient temperatures, while normally travelling, engine water temperature is generally at 85 DEG C, and magnetic clutch fan is positioned at second gear.While overtaking other vehicles, throttle strengthens, and engine load rises, and water temperature raises, and when water temperature exceedes setting temperature, for example 90 DEG C, magnetic clutch fan rises up into third gear after adhesive reaction time 0.5s, and fan consumed power increases.Overtake other vehicles after end, car load is got back to normally and is travelled, and motor is got back to normal work operating mode, load reduction, but now fan, still in third gear work, consumes relatively high power.Water temperature is continuous decrease under the fan of third gear running, until be reduced to 84 DEG C, just can be retracted into second gear.
The relative throttle of rising of water temperature has sluggishness, and when water temperature rises to clutch shift point, car load is overtaken other vehicles and finished, and enters normal driving cycle.After this water temperature can decline under third gear rotation speed of the fan, arrives 84 DEG C of water temperature shift point that are retracted into second gear.Make from and device between third gear and second gear frequently switch, add the wearing and tearing of speed clutch, meanwhile, be accompanied by the increase of fan consumed power, increased oil consumption.
