Problems solved by technology

If the fan hub is directly rigidly connected to the rotating shaft, this vibration will be directly transmitted to the rotating shaft, which in turn affects the vibration of the entire engine front accessory drive system
When the vibration is severe, the fan blades may break and the radiator may be damaged, thus affecting the reliability of the engine.
In addition, the high-speed rotating fan has a large equivalent moment of inertia. If the fan hub is directly rigidly connected to the rotating shaft, when the engine suddenly decelerates or stops, the fan will still rotate at a relatively high speed, which will increase the relative friction between the belt and the wheel. Sliding, which will increase the wear of the belt, generate noise and other problems

Description

technical field [0001] The invention relates to the heat management system technology of an automobile engine, in particular to an electromagnetically controlled engine cooling fan driving device and a realization method thereof. Background technique [0002] According to relevant research data, 5-10% of the energy of a car engine is consumed by the cooling fan of the engine. The energy lost on the cooling fan includes: (1), vibration loss during fan operation; (2), friction loss during fan operation, etc. The electromagnetically controlled one-way clutch decoupling wheel of the engine cooling fan can well solve the vibration problem of the fan during operation; the nonlinear speed regulation module can adjust the speed of the engine cooling fan according to the engine working conditions to save energy. Considering the energy saving of the car, the car cooling fan should be based on the heat load conditions of the car engine. On the one hand, the fan rotates when the heat l...
