Wide angle joint for agricultural applications

摘要

The joint is fitted with two universal joints, whose outer joint forks (7) are coupled by transverse straps on the inwards ends. The straps contain a ball or a spherical guideway. In a housing (3) inner groove, enlarged by two boundary rings (2) of special metal, sits movably a T-shaped guide disc (1). A centering element with two balls or spherical guides allows for a telescopic movement due to different diameters. The universal joint forks with the longer joint stubs (6) for coupling to the housing permit a wider angular opening without widening the housing diameter. Removing a joint fork results in an exchange of the securing rings (4), boundary rings, centering element and a guide disc.
