A coupling device includes two coaxial shafts, namely a tubular outer shaft and an inner shaft, capable of rotating about a reference axis; a wrap-around raceway formed on a first one of the coaxial shafts; an oblique raceway formed on the second coaxial shaft and a play take-up rail provided with a complementary raceway and movable relative to the second coaxial shaft parallel to a plane perpendicular to the reference axis. A row of balls is positioned to run parallel to the reference axis on the wrap-around raceway, the oblique raceway and the complementary raceway, to guide the two coaxial shafts relative to each other in translation.

Coupling device between two coaxial shafts, in particular for a steering column of a motor vehicle

Device for coupling an inner shaft and an outer shaft which slide along their common axis with balls positioned between the two shafts. The balls rest directly in axial grooves of the outer shaft and on two rails positioned in axial grooves of the inner shaft. The two rails pivot about the balls, by pressing against flanks of mating curved profile of the axial groove, and are held in place by an elastic element which presses against the bottom of the axial groove.
