Double Electromagnetic Clutch

Abstract

The invention relates to a duplex electromagnetic clutch. An annular magnet and a high-gear clutch coil are arranged in an annular groove of a clutch framework, a low-gear clutch coil and the high-gear clutch coil are assembled in a back-to-back way, and when the clutch coils fail, low-gear motive power can be output through a one-way clutch or a one-way needle bearing; the electric power is not needed at the high gear, the duplex electromagnetic clutch only needs to be in a power failure state; the friction can be controlled to be regulated and controlled through the current control by a controller, during the gear switching, the electromagnetic suction force of the high-gear clutch coil or low-gear clutch coil in the separated state is reduced, meanwhile, the electromagnetic suction force of the low-gear clutch coil or high-gear clutch coil in the combined state can be gradually enhanced, and the motive power interruption time is reduced, so the impact in the gear shifting process is small, and the gear shifting comfort is high. The duplex electromagnetic clutch has the advantages that the reliable output of the motive power is ensured, the design is ingenious, the structure is simple and compact, the use is convenient, and the duplex electromagnetic clutch is suitable for being popularized and applied in a large scale.

Description

technical field [0001] The invention relates to a duplex electromagnetic clutch, in particular to a duplex electromagnetic clutch used for automatic shifting in a transmission. Background technique [0002] In some specific construction machinery applications, when the clutch is required to rotate at high speed, the driving part and the driven part are completely separated so as not to interfere with each other, and the one-way overrunning of the overrunning clutch limits this function. At the same time, the clutch The wedges of the wedge are in contact with the inner and outer rings, so there are problems of wear and heat, which will affect their service life; for electric vehicles, mechanical clutches and traditional manual transmissions are generally used to change gears, which is complicated to operate and labor-intensive for drivers. Large, not conducive to the miniaturization of electric vehicles. Contents of the invention [0003] The purpose of the present inventi...
