Definitions

  • the present invention relates to a starter, in particular for a motor vehicle combustion engine.
  • the invention relates more particularly to a starter of the type described and represented in document FR-A-2,555,670 of the type comprising a base plate, generally produced under the shape of a cut and stamped metal plate, serving as support for the electrical box and the body of an arranged contactor parallel to the electric motor, a launcher controlled by a lever articulated on a support of the base plate produced by plastic overmolding, and of the type comprising a planetary gear reducer arranged between the motor and the shaft launcher and which has an internally toothed crown produced by plastic overmolding, and of the type in which the body of the lever articulation support and the body of the ring gear each extend through at least one hole through the base plate to secure the anchor these components on the baseplate and the type in which the articulation support and the gear ring are made simultaneously by overmolding.
  • the support of articulation and the toothed crown constitute a single piece made of plastic and, during overmolding, the supply of the part of the mold used to make the support of articulation is carried out through the plate from the toothed crown.
  • the through holes for anchoring the crown on the base plate consist of a series of a very large number of small cylindrical holes.
  • the object of the present invention is to propose a new design of an electric starter of the type mentioned previously and which remedies the disadvantages which have just been exposed.
  • the invention proposes an electric starter characterized in that the articulation support and the crown toothed are two separate components each made by a separate feed from the overmolding mold.
  • FIG. 1 shows a starter 10 intended for equip in particular a combustion engine of a motor vehicle.
  • This starter is made in accordance with the teachings of the document FR-A-2.555.670.
  • It has a base plate 12 which supports the body 14 of the starter switch including a flange 16 is fitted into a circular hole 18 formed in the part top of plate 12.
  • the base plate 12 is also used for fixing the housing 20 of the electric motor of the starter 10, for example by means of screws 22 which are screwed into the housing 20 and which pass through the base plate 12 by holes 24 formed at the periphery of the lower part of the base plate 12.
  • the hole 18 in the upper part is also surrounded by holes 26 which allow the fixing of a cover 28 to the screw means 30.
  • base plate 12 below the hole 18 for fixing the body 14 of the contactor, base plate 12 according to the state of the art has a circular through hole 32 through which extends a plastic stud 34 which is made from material by overmolding with the body of a support 36 for the articulation of a lever 38 for controlling the launcher 40 on which acts on the contactor 14.
  • the circular hole 32 is slightly flared at 42 on the face right side 11 of the base plate to increase the phenomenon of anchoring of the support 36 by the molded stud 34.
  • the base support plate 12 has a circular through hole 44 which receives, with interposition of a bearing 46, the secondary shaft 48 of a train epicyclic 50 interposed between the motor 20 and the launcher 40.
  • the planetary gear 50 also includes a crown internally toothed 52 which extends inside the housing of the motor 20 and which is produced by overmolding on the lateral face right 11 of the support plate 12.
  • the plastic for overmolding the crown 52 extends through the base plate 12 through the holes 54 to pass to through the plate and constitute as many anchoring studs of the crown 52.
  • the plastic which passes through the holes 54 extends also on the left side figure 13 of the plate base 12 to form an annular disc 56 for axial retention of pad 46 and it extends on this same face towards the high by a connecting part 58 which makes it possible to produce simultaneously by overmolding the crown 52 and the support 36 at by means of a single plastic supply of the mold overmolding which feeds the part of the mold for the production of the crown gear 52, then, indirectly through the holes 54, the part of the mold for producing the articulation support 36.
  • the hole opening 32 for the realization of the stud 34 for anchoring the articulation support 36 is a hole of non-circular section, in this case an oval section hole.
  • Each of the arcuate lights 60 extends over approximately 90 ° angle and allows four studs to be molded solid 54 for anchoring the crown gear 52.
  • the support articulation 36 and the ring gear 52 are produced under the form of distinct elements, that is to say that there is no continuity of plastic between these two components.
  • the overmolding mold for the production of a articulation support 36 and crown 52 which is not illustrated in Figure 5, has two separate power supplies in plastic, the overmolding operation of the two elements being however always carried out simultaneously in a mold unique.
  • the plastic for overmolding the crown 52 which pass through the lights 60 to make the studs anchor 54 also extends on the left side face 13 of the base plate 12 to constitute an annular disc 56 which also increases the anchoring of the toothed crown 52.
  • the number of lights 60 distributed angularly on a regular basis is not a multiple of number of planetary gear 50 satellites which, in the example illustrated, is equal to three.
