Abstract:
1. A wide-angle constant-velocity joint comprising: two forks forming input and output members of the joint, the forks having respective spherical end heads; two spiders; a central core forming a housing; one basically discoidal constraint member forming seats for the spherical end heads of said two forks, said housing receiving said constraint member for sliding movement in a transverse plane of symmetry of the central core, said constraint member moving when in use in the transverse plane, said housing having two surfaces disposed parallel to the transverse plane; a laminar ring interposed between one of said two surfaces and an opposing face of said constraint member resulting in continuous annular contact with said one of said two surfaces; and another laminar ring interposed between another one of said two surfaces and another opposing face of said constraint member resulting in continuous annular contact with said another one of said two surfaces and with said opposing face of the constraint member, wherein at least one of said laminar ring and said another laminar ring is formed of an elastic material and is shaped as a Belleville washer which bears via an outer edge on one of said two surfaces and via an inner edge against the opposing face of said constraint member.
