  • a washer is interposed between the means cushioning and rollers to avoid axial displacements of the rollers caused by the deformation of the damping means.
  • a motor vehicle includes a heat engine, which for its start-up, has a toothed launch or starter wheel (not shown) intended to be rotated by the pinion of a starter.
  • This starter includes essentially an electric motor 1 whose shaft motor 2 rotates around an axis X-X un output shaft 2 'axially aligned on shaft 2, a launcher 3 axially sliding on the shaft 2 'but integral in rotation with the latter and carrying a pinion 5 in rotation of the launch wheel toothed, and a pivoting fork 4 moving the launcher 3 axially on the shaft 2 ', between a position passive rest and an active position of engagement.

  • a damping means 20 is placed axially between the coach 17 and the crown 18 and ensures the connection rotating between them. So the depreciation means 20 intervenes axially and circumferentially between the crown 18 and the coach 17 rigidly connected to the sleeve input 10.
  • This damping means is circumferentially elastic so that the crown 18 and the coach 17 belong to a shock absorber of circumferential twist.
  • the downstream coupling part 15 consists by the rear end 16 of the output shaft 13, which has a cylindrical outer surface defining a track 21 for the rollers 22 which are interposed between this track 21 and the internal surface of the crown 18 as will be explained below.

  • Coach 17 belongs to a torsional damper comprising the means 20.
  • the crown 18 has a double function because it belongs to the coupling device 9 and cooperates with the depreciation means by belonging to a circumferential action torsional damper.
  • the crown 18 has substantially the shape of a cylinder coaxial with the axis X-X, having a wall of a certain radial thickness and having a face rear frontal 28 oriented towards the base 25.

  • the roller 22 rolls on runway 21 and on the bottom of the housing 24 facing it, in the opposite direction to R and comes to wedge in the zone of minimum width of the housing 24. The roller 22 then prevents the track 21 and the crown 18 to move relative to one another, and therefore ensures the transmission of torque.
  • a washer 33 of axis X-X is interposed between the damping means 20 and the crown 18 so as to separate the damping means 20 of the rollers 22 to avoid axial displacements of the rollers 22 caused by the deformation of the means damping 20.

  • an upstream coupling part 12 consisting of a crown 18 integral with a coach 17, rigidly connected to the sleeve 10, via damping means 20, instead of a bell in ancient art, has the advantage of allow a slight deformation of the upstream part coupling 12 without the axis of the crown 18 not be modified, the deformation being absorbed by the means damping 20, which prevents the rollers 22 are cantilevered from runway 21 and the bottom of housing 24 and therefore limits the risks flaking.
  • Figures 7 and 8 illustrate a second mode of realization of the invention in which the reliefs led 29 are constituted by the extension in the axial direction of the ribs 34.
  • the reliefs led 29 therefore do not extend radially to the periphery of the crown 18.
