Ring and yoke type universal joint

Universal joint with annulus comprising two forks provided each with two pivots journalled in bearings engaged in housings formed in the said annulus, it being possible to produce with this universal joint an elastic connection having variable torsional rigidities and limited angular deflections under torsion, between two rotating shafts, and comprising elastic elements for the radial and/or axial filtration of vibrations, characterised in that the said elements are arranged for radial and/or axial deflection limited by means of radial and/or axial shoulders forming positive mechanical abutments, that they cover the pivots integral with the forks and/or an external ring of the bearing, and that in all cases the said radial and/or axial filtering elastic elements comprise a ring coaxial with the external ring of the bearing with at least one radial abutment and/or directed towards the axis of each bearing and at least one axial abutment, the said coaxial ring thus constituting a preregulated radial and axial deflection limiting means.
