Abstract

The present invention provides an automatic test method and apparatus for vehicle air conditioner compressor electromagnetic clutch dynamic torsional moment, comprising a mainly supporting component (2), a torque revolution speed transducer (3), an electric eddy current dynamometer (4) and an electrical control system, wherein the electromagnetic clutch (1) is installed on the left end of the supporting component to form a cantilever structure, and is driven to rotate through a belt pulley of the electromagnetic clutch driven by a frequency conversion motor; the right end of the supporting component is linked with the torque revolution speed transducer and the electric eddy current dynamometer separately by a coupling, the torque revolution speed transducer and the electric eddy current dynamometer are both installed on each seat to ensure the axiality to be consistent with the supporting component main shaft. The automatic test method and apparatus can simulate air conditioner electromagnetic clutch actual use condition factually, test dynamic parameter variation regularity with the existing of revolution speed spectrum and torque loading spectrum, observe and research dynamic procedure in full, and provide science foundation for evaluating performance, lifetime and reliability thereof.

Description

technical field [0001] The invention belongs to the technical field of compressor electromagnetic clutch testing equipment, and particularly relates to an automatic testing method and device for dynamic torque of an electromagnetic clutch of an automobile air conditioner compressor. Background technique [0002] The car air-conditioning compressor is generally installed next to the car engine, and is driven by its main engine or auxiliary engine through a pulley. Except that part is directly driven by the auxiliary engine, most of them are connected to the engine pulley by the belt (1.2) on the electromagnetic clutch pulley (1.3) of the air conditioner compressor. When the clutch electromagnetic coil (1.4) is de-energized, the clutch is separated from the electromagnetic clutch pulley by the spring friction plate assembly (1.1), and the clutch pulley (1.3) is idling, as shown in Figure 1; when the clutch electromagnetic coil (1.4) is energized, the electromagnetic force make...
