Definitions

  • the present invention relates to a device for the return of a starter launcher for an internal combustion engine.
  • a starter launcher consists of a starter pinion which can move axially on a drive shaft until it engages with a ring gear located on the flywheel.
  • the starter pinion is associated with a free wheel and a drive bush made integral by an assembly cover.
  • the drive sleeve has at one of its ends helical grooves intended to cooperate with helical grooves formed on the motor shaft so as to make the assembly of the launcher rotationally integral with respect to said motor shaft.
  • the displacement of the launcher, from its rest position to its working position, in which the launcher pinion is meshed with the ring gear, is effected by the pivoting of a lever controlled in a manner known per se by an electromagnet forming furthermore a contactor.
  • the starter When the internal combustion engine has started, the starter must be returned to its rest position. This movement is effected by a pivoting in the opposite direction of the lever caused by the return spring of the contactor and the cooperation of said lever with a return device secured to the launcher and most often arranged on the drive sleeve.
  • the return device comprises a sleeve made of material, so as to have a one-piece assembly as shown for example in the document FR -A-2 145 116.
  • the return device In the case of a drive sleeve obtained by extrusion, the return device must be attached and therefore consist of parts distinct from the sleeve itself.
  • This movable pulley can be constituted by two stamped washers separated by a cardboard washer, one of the stamped washers being immobilized in translation by a rod.
  • a design as shown for example in document FR-A-2 064 768, in addition to the number of parts required, is of a complex assembly which cannot be suitable for mass production as is the case in the automotive field.
  • the device according to document DE-A-3 118 326 also has many parts.
  • the present invention solves these problems and proposes for this purpose a device for the recall of a starter launcher for an internal combustion engine.
  • a device for the recall of a starter launcher for an internal combustion engine comprising in particular a motor shaft on which a starter pinion which is secured by a cover of a freewheel and a drive bush, can slide, characterized in that it comprises a washer which has at its internal periphery a plurality of deformable claws elastically cooperating by snap-fastening with a groove formed at the outer periphery of one end of the drive bush.
  • a starter launcher consists of a starter pinion 10, one end of which comprises a toothed ring 12 intended to mesh with a toothed ring located on the flywheel motor (not shown).
  • This toothed ring 12 is extended by a cylindrical portion 14, the end opposite to the toothed ring 12 forms the track 16 of a free wheel 18 made up in particular of loaded rollers 20.
  • the cage of the free wheel consists of one end 22 of a drive bush 24.
  • a cover 26 is crimped on the periphery of the end 22 so as to make integral, the starter pinion 10, the drive bush 24 and the freewheel 18. As is well known, the cover 26 maintains two half-washers 28,29 ensuring the closing and sealing of the freewheel 18.
  • the entire launcher is guided in rotation by a ball bearing 30 housed in one end 32 of the starter casing.
  • the launcher is slidably mounted relative to a motor shaft 34 so as to be able to move from a rest position to a working position, as shown in FIG. 1, in which the launcher pinion 10 is meshed with a ring gear (not shown) located on the flywheel, the translational movement taking place in a manner known per se by the pivoting of a lever 36.
  • This return device which will now be described in more detail with reference to Figures 2 to 4 comprises a washer 38 in the general form of a cup.
  • This washer 38 includes a flat circular sidewall 40 whose outer periphery is a wall 42 perpendicular to said sidewall 40, which contributes to the stiffening of the washer.
  • a plurality of claws 44 are arranged in one piece, angularly distributed uniformly and inclined relative to the axis XX of the washer. 38 at an angle E. These claws are elastically deformable.
  • the claws 44 of the washer 38 are intended to cooperate by snap-fastening with a groove 46 (see FIGS. 5 and 6 in particular) formed on the end 48 of the drive sleeve 24.
  • This groove has the particularity of presenting with respect to the axis YY of the drive sleeve an inclination F less than the value of the inclination E of the claws 44 of the washer 38.
  • the claws 44 of the washer 38 are arranged so as to have an internal diameter d less than the minimum diameter D of the groove 46 of the drive bush 24.
  • the groove 46 has an inclination F, significantly less than the inclination E of the claws 44, causes said claws 46 to press permanently on said groove 46 since they cannot return to their rest position. This support is further accentuated by the fact that the minimum diameter D of the groove 46 is less than the internal diameter d of the claws 44.
  • a reminder device is thus produced particularly simple since it consists of only one piece: the washer 38.
  • the washer 38 is immobilized in translation and the pressing of the claws 44 on the groove 46 has the result of constituting a sufficient friction torque to prevent the washer 38 from being free to rotate.
  • the inclination E of the claws 44 is between 20 and 45 ° and preferably equal to 30 °.
  • the inclination F of the groove 46 is substantially equal to half of the inclination E of the claws 44.
  • the wall 42 of the washer 38 has at its end, on its outer periphery, a flange 50 projecting relative to said wall 42.
  • this flange 50 serves as a guide during the automatic mounting of the washer 38 on the drive bush 24.
  • the drive bush 24 has in a bore located at its end 48 helical grooves 50 intended to cooperate with helical grooves 52 formed on the motor shaft 34.
  • the helical grooves 50 of the drive sleeve 24 are obtained by stamping. This results in the outer periphery 54 of the end 48 of the drive bush 24 the presence of helical grooves 56 opposite the grooves 52.
  • the number of claws 44 of the washer 38 is a multiple of the number of helical grooves 56 so that the claws 44 are housed in said grooves.
  • This arrangement allows certain claws 44 to be in radial abutment against the grooves 56 and thus to reinforce the immobilization in rotation of the washer 38.
