ABSTRACT:
The object of the invention is to achieve a reduced cost, great lightness and possibility of mass-production of the coupling while of course retaining the qualities of a very free sliding, reliability and long life. Such qualities should in particular permit an application of the coupling in the automobile industry. The coupling is of the type comprising a cylindrical tubular sleeve which has generatrices parallel to the direction of sliding and which is intended to be fixed to one of two elements to be coupled. The sleeve defines at least two runways for at least two rollers rotatively mounted on trunnions rigid with a rod which is intended to be fixed to the other of the elements to be coupled. At the end of the sleeve opposed to the end fixed to the element to be coupled, there is provided a cover which is fixed to the sleeve by an elastically yieldable fastener. The cover defines a surface perpendicular to the axis and abutting, with interposition of a sealing element, against the adjacent end of the sleeve. This cover defines a device for guiding and sealing the rod.
