Definitions

  • the present invention relates to an internal combustion engine ignition distributor rotor for a motor vehicle, in particular of the magnetic trigger type, which rotor, driven in rotation by the distributor control shaft, consists of a sleeve, capable of to rotate on the control shaft and on which are fixed a disc with polar teeth cooperating with the corresponding disc of a stator and a feed plate.
  • the advance plate is connected to the support plate integral with the control shaft of the distributor which drives it in rotation by means of a centrifugal advance regulator.
  • a centrifugal advance regulator comprising at least two weights pivotally mounted on the support plate and which, under the action of centrifugal force provide an angular offset between the two plates as a function of the speed of the internal combustion engine and corresponding to an advance or a delay d 'ignition, against opposing springs resiliently coupling said plates together.
  • the invention makes it possible to solve this problem notably in a single operation while also remedying a difficulty inherent in the fixing and positioning of the polar disc with respect to the feed plate.
  • This disc in known manner, is fixed on the sleeve of the rotor by means of a shoulder against which it is welded, brazed or crimped and according to a certain indexing position.
  • the invention overcomes these drawbacks and relates to this effect an ignition distribution rotor of internal combustion engines for a motor vehicle, in particular of the magnetic trigger type, which rotor, driven in rotation by the control shaft of the distributor consists of a sleeve capable of swiveling on the control shaft and on which are fixed a disc with polar teeth cooperating with the corresponding disc of a stator and a feed plate, the latter being connected to the solid support plate of the control shaft of the distributor which drives it in rotation by means of a centrifugal advance regulator, characterized in that the zones or surfaces of the rotor sleeve of the axes for hooking the springs and the cam profit of the feed plate, are coated with a plastic material in a single overmolding operation carried out in such a way that it makes it possible to fix and position the polar tooth disc s on the sleeve relative to the feed plate.
  • the plastic overmolding coating consists of two different materials, one of the materials being more particularly adapted to the friction and sliding surfaces of the rotor sleeve, the other for the connection of the axes. for hooking the springs and the cam profile of the feed plate.
  • the polar tooth disc is pinched between the two respective skins of said materials.
  • the distributor consists of a housing 1 surmounted by a support bearing on the end of which pivots the control shaft 3, a rotor 2 rotated by the control shaft 3 , which rotor 2 consists in a known manner of a cylindrical sleeve 10 capable of rotating on the control shaft 3, on which sleeve 10 are disposed at its ends a disk 4 with polar teeth cooperating with the corresponding disk 5 of the stator, prevented from rotating relative to the housing 1 and to the support 1a, and a feed plate 7 connected to the support plate 6 secured to the control shaft 3 which drives it in rotation by means of a feed regulator 8.
  • the polar-toothed disc 4 of the rotor 2 is progressively angularly offset relative to the polar-toothed disc 5 of the stator under the action of the feed regulator 8 which presses on the feed plate 7 secured to the sleeve 10, said regulator 8 consisting of a support plate 6 comprising two diametrically opposed pins 9 around which masses 11 pivot according to the speed of rotation of the shaft 3, limited in pivoting by two cambered legs 12 forming stops and two other tabs 13 also obtained by bending and which, diametrically opposite, are used for hooking one of the ends of the opposing springs 14. The other end of said springs 14 is fixed to pins 15 secured to the feed plate 7 (FIGS. 2 and 3).
  • the disc 4 with polar teeth having the shape of a cross, the ends of which are bent at a right angle is positioned on the sleeve 10 at a defined distance E from the upper edge of the sleeve 10.
  • the feed plate 7 having an ovoid shape is positioned at the other end of the sleeve 10 and undergoes crimping to keep it in position, said feed plate 7 carrying the diametrically opposite pins 15 (FIGS. 4 and 5).
  • the pins 15 holding the springs 14, consequently undergoing these vibrations, are also covered with plastic.
  • the feed plate 7 in contact with the masses 11 also undergoes wear and is therefore covered with plastic material.
  • these overlaps of these different parts of the rotor 2 are produced by an overmolding operation of plastic material 16 (FIG. 6, 7), the overlap zones being the interior 16a and the exterior 16b of the sleeve 10 thus allowing the disc 4 with polar teeth to be held in position, the top 16c of the feed plate 7 as well as the upper parts 16d of the pin 15 for hooking the springs 14, the cam bearings 16e of the feed plate 7 and finally on the edges 16f and 16g of the sleeve 10.
  • the covers 16f and 16g advantageously replace the wedging and friction washers previously used. Thanks to the addition of plastic material, it is possible to give different dimensions to the cam profile 16e of the advance plate 7 according to the ignition advance curves requested without providing for modification of the plate.
  • the covering of the rotor 2 in plastic material can also be carried out in two different materials.
  • the disc 4 with polar teeth is thus positioned between the two skins 16b and 16h respective of said materials.
