Fork joint

from Wikipedia, the free encyclopedia

A fork joint is a special form of the swivel joint as a connection of a fork head and other parts with exactly one degree of freedom .

Fork joints are used, for example, where simple motion sequences such as linear pulling, pushing or axial offset compensation take place. The easiest and fastest to assemble fork joint is the AFKB joint: a combination of a fork head and a hinged spring bolt. The AFKB joint is characterized by its quick assembly and disassembly, which is also possible without assembly tools . Another version of a fork joint is an A-joint, consisting of a fork head, a split pin, washers and a split pin. Here, too, assembly and disassembly are possible without tools. Other options are ASL, AKL, AB and ABS joints. They consist of a clevis and a pin with a piercing and by securing elements for bolts and shafts with groove (SL fuse, KL-backup bayonet clip, lock washer secured).
