  • Starters of this type are known from the prior art for example by the documents FR A 2,772,473 and FR A 2,795,884 . It turned out that the mechanical organs of the launcher and more generally of the starter undergo shocks during the starting phase of the engine. Axial shocks when the launcher is moved against the toothed wheel of the engine, torsional shocks when the pinion meshes with the gear wheel. These shocks are dimensioning for the design of the pinion, and can also cause wear of the mechanical parts of the launcher and more generally of the starter.

  • leading and driven reliefs are distributed angularly equidistantly on their support surface in a circle centered on the axis of the latter, the reliefs being equal in number to the number of leading reliefs. .
  • the damping elements are grouped in pairs which each form an assembly in which the two damping elements are connected by a connecting element so that a notch is formed between them, a relief leading or a led relief being engaged in the notch.
  • the section of each relief leading or led in a plane perpendicular to the longitudinal axis X-X adopts the shape of a radial tab having two rectilinear lateral faces converging towards the longitudinal axis X-X.
  • each connecting element contributes to damping the shocks in the axial direction.
  • the ring and the member of the outlet portion delimit between them tangential housings having a radial width evolving, in a first direction of rotation, between a minimum width and a maximum width, and that a spring prestressed in compression and a roller urged by the spring in direction of the minimum width of the housing are arranged in each housing, the ring bearing substantially radial internal ribs separating two adjacent housing on each of which bears one of the springs, and in that the raised reliefs are the axial extension of these grooves internal.

  • the rear end 16 is of a diameter slightly greater than the rest of the shaft 13. The downstream coupling part 15 is engaged coaxially in the mobile ring 18.
  • the driver 17 comprises a base 25 having substantially the shape of a disc coaxial with the axis XX and having a front face 26 facing the pinion 5.
  • the driver 17 belongs to a torsion damper comprising the means 20.
  • the ring 18 has a dual function because it belongs to the coupling device 9 and cooperates with the damping means belonging to a circumferential action torsion damper.

  • a washer 33 of axis XX is interposed between the damping means 20 and the ring gear 18 so as to separate the damping means 20 from the rollers 22 in order to avoid axial displacements of the rollers 22 caused by the deformation of the damping means 20.
  • the outer edge of the washer 33 is cut to fit the shape of the reliefs carried out 29.
  • the torsional shocks propagating from the driving axle 2 towards the pinion 6 or in the opposite direction therefore pass respectively from the driving reliefs 27 to the raised reliefs 29 or from the reliefs led 29 to the driving reliefs 27 , and are damped in both cases by the deformation of the damping elements 30 located between them.
  • the connecting elements 31 and the damping elements 30 absorb part of the energy transmitted between the ring 18 and the driver 17 by deformation.
  • the clearance J is dimensioned in such a way that the deformation of the connecting elements 31 and of the damping elements 30 does not cause contacts between the led projections 29 and the base 25 of the driver 17.
  • the connecting elements 31 contribute to damping the axial shock.
  • an upstream coupling portion 12 consisting of a ring gear 18 secured to a driver 17, rigidly connected to the sleeve 10, via a damping means 20, in place of a bell in the old art, has the advantage of allowing a slight deformation of the upstream coupling portion 12 without the axis of the ring 18 being modified, the deformation being absorbed by the damping means 20, This prevents the rollers 22 cantilever with respect to the track 21 and the bottom of the housing 24 and therefore limits the risk of chipping.
  • FIGS. 7 and 8 illustrate a second embodiment of the invention in which the raised reliefs 29 are constituted by the extension in the axial direction of the ribs 34.
  • the raised reliefs 29 therefore do not extend radially to the periphery of the crown 18.

  • This second embodiment allows a simpler and less expensive manufacture of the rings 18.
  • the disengageable coupling device is of the conical clutch type, the ring gear 18 bearing at its inner or outer periphery a frustoconical friction surface capable of cooperating in a complementary manner with a frustoconical friction surface carried by the rear end 16 of the downstream part 15.
  • the ring gear 18 bearing at its inner or outer periphery a frustoconical friction surface capable of cooperating in a complementary manner with a frustoconical friction surface carried by the rear end 16 of the downstream part 15.
  • downstream coupling part extends coaxially with respect to the crown.
