Definitions

  • the present invention relates to a starter for motor vehicle.
  • the invention relates more particularly to a starter of the type comprising an electric motor of which the output shaft rotates a coaxial launcher with interposition of a gear reducer, in particular of the type with planetary gear.
  • the friction device includes a annular friction disc which is rotatably linked to the crown and which is in axial abutment against the internal face of one of the flanges of the case against which the friction disc is stressed axially by a frustoconical elastic washer.
  • This design therefore calls for at least two additional components, compared to a train epicyclic without torque limiting device, i.e. the friction washer and elastic frustoconical washer.
  • the object of the invention is to propose a new design of a starter of the type mentioned previously which remedies the disadvantages which have just been mentioned.
  • the invention provides a starter for motor vehicle of the type comprising a housing in which is arranged an electric motor whose output shaft drives in rotation a coaxial launcher with the interposition of a reducer having an internally toothed crown which is mounted in a housing cavity in which it is immobilized in rotation and which comprises an annular skirt cylindrical toothed internally closed at one of its axial ends by a radial wall pierced at its center for the passage of a gearbox output shaft, the crown toothed comprising an elastically deformable zone in twist which is arranged at one of the axial ends of the internally toothed skirt to intervene between the latter and an adjacent part of the crown comprising means for immobilizing the crown in rotation in its cavity, characterized in that the deformable zone elastically consists of a series of link arms elastically deformable, of substantially axial orientation, which connect the axial end of the toothed skirt to the part adjacent to the ring gear comprising the means immobilization in rotation.
  • Part 1 of a motor vehicle starter 10 of the type comprising a electric motor 12 whose rotor 14 is mounted rotating, around an axis X-X inside a rear part 16 of the starter housing which is completed by a front part 18 hood-shaped.
  • the upper part (not shown in detail) of the starter 10 includes an electromagnetic contactor which, by means of a fork 20 in the form of a fork, acts known manner on a launcher 22 which is slidably mounted on a starter shaft 24 coaxial with the output shaft 26 of the engine electric 12.
  • the output shaft 26 of the electric motor 12, linked at rotation to rotor 14, projects axially forwards beyond of the front face 28 of the stator 30 and it rotates a pinion 32 which is the sun pinion of a planetary gear train 34 which constitutes a gear reducer interposed between the shaft 26 and the starter shaft 24.
  • the sun gear 32 cooperates with the pinions planetary gears 34 satellites 34 which are rotatably mounted around axes 38 which are carried by a radial plate 40 planet carrier which is linked in rotation to the output shaft 42 of the reducer 34 which is a hollow shaft inside which is received the rear splined end (not shown) of the shaft launcher 24 for the rotational drive of the latter by the output shaft 42.
  • the planetary gear 34 also includes a crown 44 internally toothed inside which mesh the satellites 36 and which is immobilized in rotation relative to the starter housing 10.
  • the toothed crown 44 produced in accordance with lessons of the invention, consists essentially of by a cylindrical annular skirt 46 which is open axially at its rear end 48 and whose front end is closed by a radial wall 50 which is pierced in its center of a hole 52 in which, the rotation shaft is mounted exit 42.
  • the peripheral surface 56 of the skirt 46 is a cylindrical surface and the ring gear 44 is received in a complementary hollow cylindrical cavity 58 formed in the cover 18 of the starter housing 10 and which is open axially backwards to allow axial insertion, from right to left considering figure 1, from ring gear 44 in the cavity 58, the latter being axially delimited by a radial shoulder 60.
  • the internal cylindrical surface of the skirt 46 is toothed and it has for this purpose a series of teeth 62 which extend over the entire axial length of the internal surface toothed 61, that is to say notably substantially to the bottom of the ring gear 44 formed by the internal radial face 64 of the wall 50.
  • the front axial end portion of the skirt 46 comprises a series of recesses 70 distributed angularly from evenly around the X-X axis of the ring gear 44.
  • the recesses 70 which pass radially through in part the thickness of the material constituting the skirt 46, define between them as many link arms 72 each of which extends axially to connect the skirt 46 to the radial wall of background 50.
  • the set of arms 72 constitutes the zone 66 elastically deformable in torsion, i.e. their elastic deformation allows, by transverse bending arms 72, to generally rotate the skirt 46 by relative to the wall 50.
  • the ring gear 44 is linked in rotation to the housing 10 by a series of lugs 74, here three in number, of which each extends axially forward from the face external radial 76 of the wall 50.
  • each lug 74 is in the extension of the external cylindrical face 56 of the skirt 46 and each lug 74 is received in a housing complementary formed in the bottom shoulder 60 of the cavity 58.
  • each recess 70 extends axially towards the rear in the bottom wall 50 to open into the front radial face 76 of the latter, the recess being delimited radially towards the interior by an interior edge 75.
  • the toothed skirt 46 can rotate relative to the wall 50 and therefore relative to the housing.
  • the starter 10 thus comprises elastic damping means in twist arranged at the gear reducer 34 which do not use any additional components compared to a starter fitted with a conventional planetary gear, only the gear design being changed in accordance with the teachings of the invention.
  • the invention is not limited to the case of a reduction gear with planetary gear but also found to apply in other case, for example when the reduction gear 34 is a gear offset gears with a ring gear internally.
