Coupling and method of manufacturing same

摘要

A coupling for a vehicle steering unit includes a first linking section (4a) including two leg portions (42,44) extending from a hub portion (40) and a second linking section (4b) including two wings (19A,19B) extending from and integrated to the hub portion and protrusions (56,58) on the wings pierced with holes (4d,4e) for the passage of a tightening bolt (16) for tightening the wings to bear radially on a shaft. The wings are terminated at a longitudinal slot extending substantially in parallel to an axis (46) of rotation of the coupling. This longitudinal slot is wide enough to allow the passage of the shaft.
