Definitions

  • the present invention relates to a starter for a motor vehicle thermal engine provided with a base plate with optimized configuration.
  • a rotating electric machine in the form of a starter provided with a launcher capable of transmitting rotational energy from the starter to a crankshaft of the heat engine via a starting ring.
  • This launcher is mounted movable in translation on a drive shaft between a rest position in which the teeth of a drive pinion are clear of the teeth of a starting ring secured to the crankshaft of the heat engine, and a position of 'activation in which the teeth of the drive pinion mesh with teeth of the starter ring gear.
  • the connection between the launcher and the drive shaft is made via splines provided in the driver cooperating with splines of complementary shape provided in the drive shaft.
  • a speed reducer for example of the epicyclic type, is interposed between the rotor shaft and the drive shaft.
  • This speed reducer comprises a planet carrier having a plate secured to the drive shaft. Satellites rotatably mounted on the planet carrier mesh on the one hand with a ring gear carried by a base plate and on the other hand with a planetary pinion secured to the shaft of the electric motor.
  • Requirement FR 3 013 396 A1 discloses, among other things, a starter for a thermal engine according to the preamble.
  • the plastic layer between the metal of the pad and the bushing thus makes it possible to support the angle taken by the bushing generated by the bending of the drive shaft in order to limit excess edge pressure.
  • the invention thus makes it possible to improve the wear life of the system.
  • a thickness of the plastic layer is at least 0.5mm.
  • the plastic portion comprises at least two stop parts mounted between the crown and the cylinder head of the electric motor. This keeps the crown radially in the cylinder head.
  • the crown comprises projections extending from an external periphery of the crown.
  • damping pads are mounted between the projections and the abutment parts of the plastic portion. Such a configuration makes it possible to absorb the shocks suffered by the toothed ring.
  • the toothed ring is part of the plastic portion. This makes it easier to complete the whole thing.
  • the bearing has an axial length greater than 5mm. This helps minimize the pressure experienced by the pad when the launcher comes into active position.
  • the metal plate comprises a main portion and a shoulder extending axially relative to the main portion on one end located on the side of the bearing.
  • the bearing has an axial length greater than an axial thickness of the main portion of the plate.
  • the invention is particularly advantageous for this type of configuration where the overhang between the bearing and the base plate is significant.
  • a drive pinion mounted on the drive shaft is positioned outside a starter support.
  • the fatigue resistance of such a system is improved, which generates significant internal stresses due to the overhang of the shaft when the launcher is in the active position.
  • the starter further comprises a front bearing mounted between the support and the drive shaft to guide the drive shaft in rotation, a launcher comprising helical splines cooperating with helical splines of the shaft mobile drive between a rest position and an active position and in that, in position active, the launcher abuts against a shoulder of the drive shaft located between the base plate and the front bearing.

  • Each winding is composed of a continuous conductor wound around the polar mass in the direction of its thickness so as to form concentric concentric turns of increasing diameter.
  • the rotor 18 comprises a pack of sheets provided with grooves for mounting pin-shaped electrical conductors. These conductors are connected together to form a rotor winding 27 in connection with conductive blades 30 belonging to a collector 31 with an electrically insulating body secured to the shaft 19 of the electric motor 16.
  • the winding 27 is a continuous wire.
  • the brushes 34 rub on the collecting blades 30 of the collector 31 to power the rotor winding 27.
  • the brushes 34 belong to a brush holder 35 equipped with cages for guiding and receiving the brushes 34. These brushes 34 are biased towards the blades collectors 30 by springs 36, for example of the spiral type.
  • the brush holder 35 is integral with a metal rear flange 39 having in its central part a housing for mounting a bearing 40 of the needle bearing type.
  • the flange 39 is used for rotating the rear end of the shaft 19 of the electric motor 16.
  • the front end of the shaft 19 penetrates, via a section of reduced section, inside a bore made in the rear part of the drive shaft 11, a bearing 43 being interposed between these two elements 19, 11.

  • a shock absorption device 67 comprises a spring 68 biasing the pinion 15 against a stop 69 in the rest state. In the event of an impact with the teeth of the starting crown, the spring 68 is compressed by the translational movement of the pinion 15 which then tends to move backwards relative to the stop 69.
  • the pinion 15 is mounted on the drive shaft 11 outside the support 23 of the starter 10. Such a configuration of starter 10 called “outgoing pinion" generates significant internal stresses due to the overhang of the drive shaft 11 when the starter 12 is in active position.
  • the launcher 12 is slidably mounted on the drive shaft 11 and comprises a driver 72 configured to be actuated by the pivoting control lever 58, and a freewheel 73 with rollers interposed axially between the driver 72 and the pinion carrier 62.

  • the free wheel 73 comprises a plurality of pre-load springs 83 each mounted between an edge of a ramp 79 and a corresponding roller 82.
  • the locking direction of the freewheel 73 is illustrated by arrow A (cf. figure 4 ).
  • a 25% reduction in the value of the coefficient ⁇ allows the number of starter operating cycles to be doubled.
  • the definition of a starter respecting the range ⁇ makes it possible to significantly reduce the level of contact pressure between the rollers 82 and the rings 76, 78 while optimizing the size of the starter 10.
  • the driver 72 further comprises a washer 86 defining with a transverse wall of the driver 72 a groove for receiving the fingers of the lower end of the lever 58 in the form of a fork.
  • the upper end of the lever 58 is mounted in a known articulation manner on a rod 87 elastically connected to the movable core 54 via a spring 88, called a tooth-to-tooth spring, housed in the movable core 54.
  • the driver 72 is internally equipped with helical splines 90 in complementary engagement with external helical teeth 91 carried by the drive shaft 11 in the vicinity of its rear end of larger diameter (cf. figure 1 ).
  • the launcher 12 integrating the free wheel 73 is thus driven by a translation movement when it is moved by the lever 58 between a rest position in which the pinion 15 is released from the starting crown of the thermal engine and an active position in which the pinion 15 engages with the starting ring of the heat engine.
