Automatic clutch device

An automatic clutch device comprises an outer sleeve, an inner sleeve, an inner sleeve and a clutch assembly. A sinking groove is formed in one side of the outer sleeve; the clutch groove is formed inthe inner wall of the outer sleeve; the clutch rod is arranged in the clutch groove; the core seat is arranged in the sinking groove; and the core column is connected with the core seat. Compared with the prior art, the automatic clutch device has the advantages that the automatic clutch device can be automatically closed when the rotating speed of the diesel engine is higher than that of the generator, and can be automatically separated when the rotating speed of the diesel engine is lower than that of the generator. Therefore, the rotating speed of the generator is always kept at the ratedrotating speed (such as 1500r/min), the normal work of the generator is not influenced by the fluctuation of the rotating speed of the diesel engine, and the power generation quality of the generatoris further ensured. 一种自动离合装
