Heavy truck torsion damping electromagnetic clutch assembly

Abstract

The invention provides a heavy truck torsional vibration damping electromagnetic clutch assembly, belonging to the technical field of electromechanics. The invention solves the problem of poor structural reliability of the existing electromagnetic clutch assembly in the vibration damping process. The heavy truck torsional vibration damping electromagnetic clutch assembly comprises a flanged shaft, and a magnetic disk, a fan connecting pad and a fan which are arranged on the outer side of the flanged shaft, wherein the magnetic disk is fixed with the flanged shaft in the circumferential direction; the magnetic disk is also provided with an electromagnetic clutch mechanism; the fan connecting pad comprises a fan active connecting pad and a fan passive connecting pad which are arranged between the magnetic disk and the fan; the fan passive connecting pad is fixedly connected with the fan; the electromagnetic clutch mechanism can fix the circumferential position between the fan active connecting pad and the magnetic disk in the electrifying process; and a plurality of elastic parts are arranged between the fan active connecting pad and the fan passive connecting pad. The heavy truck torsional vibration damping electromagnetic clutch assembly has the advantages of high damping stability and long service life.

Description

technical field [0001] The invention belongs to the field of electromechanical technology, and relates to an electromagnetic clutch assembly, in particular to a heavy truck torsion damping electromagnetic clutch assembly. Background technique [0002] The structure of the electromagnetic clutch assembly applied to the automobile engine generally includes a flange shaft and a fan, a fan connection plate, a driving disc and an electromagnetic coil that are sequentially sleeved on the outside of the flange shaft. The output power end of the engine is connected, the driving disc is fixed circumferentially with the flange shaft and rotates synchronously with it, the fan is fixedly connected with the fan connecting disc, and a bearing is arranged between the fan connecting disc and the flange shaft. When working, if it is in a low-speed working state, the electromagnetic coil is not energized, and the fan connection plate and the fan receive the power transmitted by the flange sha...

Problems solved by technology

[0003] However, in the process of switching from the low-speed state to the high-speed state, because the fan connection plate and the disk that are fixedly connected to the fan are directly connected rigidly through the coupling piece, the low-speed rotating fan and the fan connection plate will It will cause a large impact on the high-speed rotating driving disc and the engine shaft that rotates synchronously with the driving disc, affecting the working state and service life of the engine

[0004] In response to this problem, people have designed a technical solution, which increases the inner diameter of the driving disc and arranges vulcanized rubber between the driving disc and the flange shaft for buffering and shock absorption. The rigidity requirement of the flange shaft is relatively high, so the technical scheme of connecting the vulcanized rubber on the flange shaft is very likely to cause the joint between the vulcanized rubber and the flange shaft to fall off or be damaged due to vibration or its own torque during use, thus making the The entire electromagnetic clutch assembly is not working properly
