Background

Conventional power plants such as electric motors, internal combustion engines, etc. basically transmit torque and rotational speed to the load side at a single output. Accordingly, the conventional clutch also uses a single output shaft of the power plant as a single input shaft of the single clutch.

The invention provides a technical scheme of a double-input-shaft single-output-shaft electromagnetic double clutch, and particularly relates to a concentric nested double-input-shaft single-output-shaft electromagnetic double clutch. When the power equipment uses the concentric nested double output shafts as double power output, the double clutch separates or combines the double input shafts of the power equipment with the single driven shaft, can separate or combine any one driving shaft in the double input shafts with the single driven shaft, can simultaneously transmit or stop transmitting the transmission power simultaneously output by the double input shafts to the single driven shaft in a mode of combining or separating with the single driven shaft, and can also perform output conversion in a single outer shaft, a single inner shaft and double shaft power at any time. The invention provides a new technical scheme for selecting a double clutch required in the field of power transmission, particularly provides a novel electromagnetic type double clutch for devices on the load side such as a motor and the like to simultaneously receive and selectively receive various power transmission modes when being used in the fields of electric automobiles, ships, spaceflight, machine tools and the like.
