Abstract
There is provided between a needle plate (9, 10) and a slide (6) which is interposed between a trunnion and a track a return spring (14) formed by a wire of resilient metal having at least one coil (C) which surrounds the slide and two end portions (14b) of the wire which are hooked to the needle plate. This spring operates under bending and compressive stress in its mean plane.
Claims7
An arrangement comprising a planar raceway and a slide which are capable of undergoing a reciprocating motion with respect to each other in directions parallel to said raceway, rolling members between the raceway and slide, a cage generally parallel to said raceway and having ends on opposite sides of said slide, said cage maintaining the rolling members in position, and spring means connected between only said slide and said cage for maintaining said slide centrally disposed relative to said cage, said spring means consisting of a return spring having a substantially flat configuration having a mean plane parallel to said raceway and comprising a wire of resilient metal defining at least one coil surrounding said slide and two end arm portions which extend from said coil to ends remote from said coil, and connecting means for connecting said end arm portions to respective ends of said cage.
A homokinetic universal joint of the tripod type comprising a tripod element carrying trunnion means, a barrel defining two planar raceways for each trunnion means, and an arrangement interposed between each trunnion means and each respective planar raceway and comprising a slide capable of sliding relative to the respective raceway in a direction parallel to said raceway, rolling members interposed between said raceway and said slide, a cage generally parallel to said raceway and having ends on opposite sides of said slide, said cage maintaining said rolling members in position, and spring means connected between only said slide and said cage for maintaining said slide centrally disposed relative to said cage, said spring means consisting of a return spring having a substantially flat configuration having a mean plane parallel to said raceway and comprising a wire of resilient metal defining at least one coil surrounding said slide and two end arm portions which extend from said coil to ends remote from said coil, and connecting means for connecting said end arm portions to respective ends of said cage.
