Description
Technical Field
The invention relates to the technical field of automobiles, in particular to an electronic control silicone oil fan clutch calibration system.
Background
In conventional commercial vehicle cooling systems, the cooling fan speed is typically controlled by a temperature controlled silicone oil fan clutch. The bimetallic temperature sensor is installed at the front end of the temperature control silicone oil fan clutch, the bimetallic thermal expansion coefficients are different, the air outlet temperature of the cooling module is sensed, the temperature sensing module is enabled to be twisted and deformed and drives the pin shaft and the valve plate to generate opening and closing actions, a valve of a silicone oil channel inside the clutch assembly is opened, silicone oil in an inner working cavity is controlled, the amount of the silicone oil can control the engagement or separation of the driving plate and the driven shell, and therefore the aim of controlling the rotating speed of a fan connected with the driven shell is achieved.
When the load of the engine is increased, the water temperature is increased, the temperature of airflow blown from the radiator is increased, the hot air enables the bimetal temperature sensor to be heated and to be twisted and deformed to drive the valve pin and the valve plate to rotate, and the opening degree of the oil inlet is controlled through the deformation of the temperature sensor. When the oil inlet is opened, silicone oil enters the working cavity from the oil storage cavity, the fan clutch is engaged under the action of liquid friction, and the driven shell rotates along with the driving plate to drive the fan to run at a high speed. At the moment, the silicone oil clutch is in a meshing working state.
As the engine load decreases, the temperature of the hot air stream blowing from the radiator decreases. When the temperature of the hot air passing through the temperature sensor is lower than a certain temperature, the temperature sensor rotates to drive the valve pin and the valve plate to close the oil inlet hole. The silicone oil in the working cavity returns to the oil storage cavity under the action of centrifugal force, the fan clutch returns to a separated state, and the fan is in idle running or slipping rotation, so that the aim of adjusting the water temperature of the engine is fulfilled.
In practical application, the aim is to control the temperature of a flowing medium in a cooling water channel and the like, and because the bimetal temperature sensor senses the outlet air temperature of a cooling module, the outlet air temperature has high hysteresis and thermal inertia, and is influenced by a plurality of factors such as a temperature regulator, an air conditioner, vehicle body ventilation and the like, so that large deviation and over-regulation tend to exist. In addition, the temperature control clutch can only realize two states of engagement and disengagement, and the corresponding fan rotating speed is only two rotating speeds under the same input rotating speed, so that stepless regulation according to requirements cannot be realized.
Therefore, the electric control silicone oil fan clutch is provided in the related art, the rotating speed of the fan can be accurately controlled according to the heat dissipation requirement, stepless regulation and control according to the requirement are realized, the responsiveness is improved, the separation rotating speed can be reduced, the energy conservation and emission reduction are realized, the noise is reduced, and the comfort is improved.
The electric control silicone oil fan clutch is mainly characterized in that the silicone oil control valve realizes electric control, and the on-off time of the valve can be continuously and gradually controlled according to the input signal (PWM) of the whole vehicle or an engine, so that the silicone oil flux is continuously controlled, and the stepless control of a clutch driven piece is realized. Because the input signal is directly obtained from the control target parameters such as water temperature, the intermediate control links are greatly reduced, the responsiveness is improved, and the overshoot and thermal inertia can be greatly reduced by adjusting the intermediate rotating speed as required.
After the fan clutch is electrically controlled, the performance debugging and calibration control of the electrically controlled silicone oil fan clutch in the whole vehicle are very important, the performance and the energy-saving effect of the whole vehicle can be directly determined, and various indexes such as reliability, comfort and the like are even influenced. In the related technology, after open-loop and closed-loop performance tests are carried out on a common electric control silicone oil fan clutch, the electric control silicone oil fan clutch is installed on a whole vehicle, and PID parameters and feedforward MAP calibration are carried out according to a real vehicle control computer program.
The calibration needs to occupy the resources of the whole vehicle for several days, and a driver and a tester are matched in the whole process, so that a lot of manpower and material resources are spent. And the control condition of the whole vehicle is not stable enough, so that the repeated work is more and the calibration precision is poorer. In addition, if the matching computers for the vehicles are different, the internal programs and algorithms are different, the calibration parameters may change greatly, and corresponding different whole vehicles need to be called for recalibration, so that the work is complicated and difficult, and the time and resource consumption is high.
