Abstract
The utility model belongs to the partial modification of internal combustion engine cooling system. The existing cooling fan of a vehicle engine usually adopts silicone oil clutch, which has the defects of slow movement, low fan speed, complicated structure, high processing request, incapability of being separated completely, etc. The utility model adopts new materials as the temperature sensing element, and with simple structural form, the effect of high sensibility, firm combination and thorough separation is reached. The utility model has simple preparing process, small axial dimension, and convenient installation and maintenance, without changing the structure of the original vehicle. Meanwhile, energy consumption can be saved and the utility model can be widely used for temperature regulation of various internal combustion engine cooling systems.
Description
This model utility belongs to the part of internal-combustion engine cooling system and improves.
The structural type of motor car engine fan clutch is more.Electromagnetic type, pneumatic machinery formula, silicone oil formula etc. are arranged.Wherein the silicone oil formula is used more.
Silicone oil formula fan clutch is a kind of structure that occurs the sixties, is applied on the car at first more, because of having the advantage of obvious saving fuel oil, has been applied on the engine blower of the bigger heavy-duty car of consumed power at present.The MS635J motor (177KW) etc. of the TD-120 motor (243KW) of Sweden, France for example.The liberation CA141 motor car engine of China is equipped with vapour and grinds I type silicone oil formula fan clutch.(" automobile construction " Hubei Science Press in August, 1989 version).
Silicone oil formula fan clutch is that the bimetallic material lower with sensitivity, that thermal hysteresis is bigger is a heat responsive element.The fan clutch that utilizes the very big silicone oil transmitting torque of viscosity to manufacture.When the helical bimetallic strip is caught a cold thermal distortion, drive valve block and rotate, open and close the oil inlet and oil return hole between follower plate in the oil pocket, silicone oil flowed reach the clutch of clutch between oil storage chamber and active chamber.Silicon oil clutch, clutch is slow, and the rotating speed of fan is lower than the driving shaft rotating speed." and exist complex structure, processing request height, axial dimension big, shortcoming such as can not separate fully." (" vehicle energy saving principle and measure " the Fujian People's Press in April, 1986 version).
For invent a kind of simple in structure, clutch is effective, and fan clutch that can be scalable, special development the utility model.
The utility model adopts the NiTi(NiTi be better than bimetallic material) shape memory alloy material is that heat responsive element, the displacement of roller on rising angle (6) (inclined-plane) they are the fan clutch of clutch pattern.
The NiTi(NiTi) marmem is a kind of new function material in the world today.It has excellent shape-memory properties, superelasticity and high damping properties.Spring element with this alloy is made can be out of shape arbitrarily at the low-temperature martensite state.When temperature was elevated to serviceability temperature, element restored to the original state and work done immediately.Be characterized in: " in light weight, highly sensitive, thermal hysteresis is little, driving force is big.”
Accompanying drawing 1 is the structure front view of internal-combustion engine temperature control electric fan clutch.
Temperature-controlled fan clutch is made up of driving disc (1) and driven shell (2) fan.Driving disc (1) and driven shell (2) side by side, between keep certain interval, the roller (5) on driving disc (1) and driven shell (2) be when compressing, the clutch combination.When roller (5) broke away from driven shell (2), clutch separately.Upward establish a clutch point at driving disc (1) every hexagonal angle.Totally three clutch points.Every by one piece of memory alloy spring (3), one piece of biasing spring (4) and roller (5) formation that coupling is suitable.When motor below normal working temperature, start, when turning round.Biasing spring (4) is pushed roller (5) on the low degree at driving disc (1) rising angle (6).At this moment, clutch separation, the zero load idle running of fan.
When the engine load increase, when the coolant temperature in the radiator raises.Gas flow temperature by radiator increases.The gas flow temperature that blows to driving disc (1) clutch point restores to the original state immediately to roller (5) and biasing spring (4) work done memory alloy spring (3).Drive and sail roller (5) and move, compress with driven shell (2) to the point that raises.At this moment, clutch combination, fan full load operation.
When the gas flow temperature that blows to the last memory alloy spring (3) of driving disc (1) is lower than the motor normal working temperature.The low-temperature martensite that memory alloy spring (3) appearance can be out of shape arbitrarily.The active force of biasing spring on the other side (4) itself drives sails roller (5) and memory alloy spring (3) disengaging extruding point, and the low degree to rising angle (6) moves.Clutch separation, fan idle running.
Through on liberation CA115 type car, testing.When water temperature (water tank probe temperature) when being higher than 85 ℃, the clutch combination.When water temperature is lower than 75 ℃, clutch separation.Prove that this structural principle is highly sensitive, rub little, in conjunction with firmly, separate thoroughly, meet the requirements.
Temperature-controlled fan clutch is compared with using at present both at home and abroad more silicone oil formula fan clutch, have have a narrow range of temperature, highly sensitive, simple in structure, processing and fabricating is easy, axial dimension is little, do not change primary car structure, installation and maintenance are convenient, adapt to wide characteristics. To shorten the engine warms time, save energy resource consumption, improve effective engine power, reduce the wearing and tearing of engine cold state, reduce noise that fan causes, the service life, the environmental contamination reduction texts that prolong the fan belt be remarkable, be better than similar products at home and abroad, be applicable to the adjustment of various internal-combustion engine cooling systems.
Claims (1)
1, a kind of internal-combustion engine temperature-controlled fan clutch has driven shell of driving disc [1] [2] and fan etc., it is characterized in that: keep certain interval driving disc [1] and the clutch between driven shell [2] side by side to be determined by the clutch state of roller [5] with driven shell [2].Go up at driving disc [1] and to establish a clutch point every hexagonal angle, totally three clutch points, every has one piece of heat responsive element NiTi (NiTi) memory alloy spring [3] and one piece of coupling biasing spring [4] folder one roller [5] to place in the rising angle [6] (inclined-plane).Memory spring [3] places rising angle [6] reduction point one end coupling spring [4] to place rising angle [6] rising point one end to constitute the pattern of mobile clutch.
