Technical Field

[0001] The utility model relates to the technical field of clutches, in particular to a clutch capable of automatically aligning threaded locking. Background Art

[0002] A clutch is a mechanical device used to connect and disconnect two rotating parts in a transmission system, usually between the engine and the transmission. When the mechanical system is subjected to excessive load or external shock, in order to automatically limit torque transmission and prevent the equipment from being overloaded and damaged, we need a clutch that automatically aligns and locks the threads.

[0003] As high-horsepower tractors continue to be introduced into the agricultural machinery market, there are certain problems with the wider width of the supporting agricultural machinery and the narrowness of the field roads. Many agricultural machinery have adopted folding to solve the related problems. The power transmission usually adopts a tooth clutch, but it lacks an automatic alignment function during installation, which increases the time consumption of the assembly process.

[0004] Therefore, we provide a clutch that automatically aligns and locks the thread. Utility Model Content
