Definitions

  • the present invention relates to a starter launcher stop device 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.
  • a stop device generally consisting of a ring attached to the end of the motor shaft on the ring gear side cooperating with the end of the launcher pinion in the working position, that is to say in the position where the starter gear is engaged with the ring gear.
  • a configuration of this type, as illustrated in document FR-A-2 622 641 requires a portion of the driving shaft projecting relative to the starter pinion, or even relative to the casing of the starter assembly, which makes it difficult and costly. effective protection of said motor shaft portion against various mechanical attacks resulting from the environment in which the starter must operate.
  • a stop device incorporated in the launcher is used, this device being formed by the cooperation of the ends of the helical splines formed on the drive sleeve of the launcher and the motor shaft.
  • the launcher is no longer a simple assembly that is reported on A motor shaft whose rear part is pre-equipped in particular with the armature of the electric starter motor. Indeed, it is then necessary to introduce through said rear part the starter drive bushing, to produce the armature of the electric motor and then to finish assembling the different components of the starter in situ.
  • a starter launcher for an internal combustion engine comprising a stop device comprising in particular a motor shaft, on which a starter pinion which can be secured to a free wheel and a bushing d driven by a cover, the starter pinion having over its entire length a bore inside which the motor shaft moves, characterized in that said stop device consists of a ring and a ring d 'stop embedded in a semi-cylindrical groove formed in the bore, said stop ring cooperating with the ring fixed on the end of the motor shaft.
  • a starter launcher consists of a starter pinion 10, one of the ends 12 of which comprises a toothed ring 12 intended to mesh with a toothed ring located on the flywheel (not shown).
  • This toothed ring 12 is extended by a cylindrical portion 14, the end opposite to the toothed ring 12 constitutes the track 16 of a free wheel 18 made up in particular of loaded rollers 20.
  • the cage of the free wheel 18 is constituted by one end 22 of the drive sleeve 24.
  • a cover 26 is crimped on the periphery of the end 22 so as to make the starter pinion 10, the drive bush 24 and the freewheel 18 integral. 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, represented in FIG. 1, to a working position, represented in FIG. 2, in which the pinion launcher 10 is meshed with the ring gear (not shown) located on the flywheel, the translational movement being effected in a manner known per se by the pivoting of a lever 36.
  • the drive shaft 34 includes a first cylindrical seat 38 which is received in a central bore 40 of the starter pinion 10.
  • Bushings 42, 43 allow the starter pinion 10 to slide and journal on the motor shaft 34.
  • the motor shaft 34 Adjacent to the first cylindrical bearing surface 38, the motor shaft 34 comprises a second cylindrical bearing surface 44 of larger diameter at the outer periphery of which are formed helical grooves 46 intended to cooperate with helical grooves 48 formed in a bore located on the rear part of the drive sleeve 18.
  • the front end of the ring gear 12 of the starter pinion 10 is extended by a cylindrical barrel 50 having a groove 52 (see FIG. 3) into which a closure plug 54 is clipped which closes the central bore 40 and thus ensures the protection, in particular of the motor shaft 34 against any external mechanical attack.
  • the front end of the motor shaft 34 is extended by a threaded end 56, onto which is screwed a ring 58 having on its rear part a cylindrical portion 60 of the same diameter as the first cylindrical seat 38 of the motor shaft 34 and on its front part a cylindrical flange 62 whose outside diameter is equal to the diameter of the bore 40 of the starter pinion 10.
  • the stop ring 66 slides on the first cylindrical seat 38 of the 'engine shaft 34 until it comes into contact with the cylindrical flange 62 which the ring 58 has.
  • the stop ring 66 and the ring 58 constitute the starter stop device, a device which is located under the starter pinion 10 which allows the motor shaft 34 not to be protruding and therefore to be protected regardless of the position of the launcher.
  • means for circulating the air contained in the zone 68 are provided.
  • These means consist of longitudinal grooves 70 formed at the periphery of the flange 62 of the ring 58 making it possible to put the zone 68 in communication with longitudinal grooves 72 formed in the bore 40 in line with the cylindrical portion 14 of the starter pinion 10 and emerging at the back of it.
  • the air which is expelled from the zone 68 is finally evacuated by the helical splines 46 of the motor shaft 34.
  • the ring 58 could be made integral in translation with the drive shaft 34 by a stop ring.
  • said ring 58 could be constituted by a screw having the same shape, the drive shaft 34 being provided at its end with a tapped hole.
