Definitions
- the present invention relates to a starter, and more particularly to a starter for an internal combustion engine of a motor vehicle.
- a starter for a motor vehicle essentially comprises an engine electric and an electromagnetic actuator.
- the object of the invention is to take advantage of this support piece comprising the second half-steps.
- the crown makes it easy and economical to replace this seal sealing.
- the electromagnetic actuator 14 comprises a casing 15 of general shape cylindrical whose front portion, forming a carcass, comprises an annular shoulder 18 consisting of a first radial annular face 20 facing towards the front and one face cylindrical side 22.
- a second radial annular front face 21 of the front part is substantially perpendicular to the longitudinal axis A2 of the actuator electromagnetic 14.
- the electric motor 16 is fixed to the starter nose 12 by screws of fastening 34, in the form of tie rods, which longitudinally pass through the housings 15 and 17 and which are screwed into tapped holes formed here in the starter nose 12.
- FIG. 1 of FR-A-2 699 605 Such a ring is visible in FIG. 1 of FR-A-2 699 605 showing also the pinion that has in front the launcher to mesh with said crowned.
- the electromagnetic actuator 14 is of known structure, which will not be described in detail, and it allows, in addition to the power supply of the engine electrical 16 by a system called contactor, to cause the pivoting of the lever actuator 40 via an output member 50 whose free end front carries a transverse pin 52 which is received in a groove 54 formed in the upper end 56 of the actuating lever 40.
- the output element consists of a rod with a hole at the front end for passage of the pin 52.
- the other end of the rod has a head for pressing a spring tooth against tooth (not visible) surrounding the stem and whose front end is supported on a mobile core 151 slidably guided by the casing of the housing 15 closed by a hood.
- the carcass carries at least one coil 152 carried by a support 153.
- the sliding gear then moves towards the crown of starting the engine of the motor vehicle.
- the lever 40 is therefore allowed to pivot about an axis A3 described below and to support by its lower end on the launcher 36 as described below.
- the lower part 60 of the operating lever 40 has a shape of fork which cooperates with a control surface 62 of the launcher 36.
- the first two half-bearings 64 transversely opposed, are formed to the end of a horizontal plate portion 68 which protrudes from the inner side facing the rear of the starter nose 12.
- the support piece 82 of the actuating lever 40 has a symmetry of design relative to a median vertical plane that contains the longitudinal axes A2 and A1 of the electromagnetic actuator 14 and the electric motor 16 and which corresponds to the section plane of Figure 1.
- the intermediate portion 88 of the support piece 82 is a vertical element which extends in a plane perpendicular to that of the front portion 80 and which comprises a first cylindrical upper concave surface 90 which is complementary to the shoulder 18 of the electromagnetic actuator 14.
- the rear portion 92 has the general shape of a tube sector. It involves on its underside of the ribs 94. Two of them extend down along of each of the longitudinal edges, and a third extends downwards transversely to the rear end of the portion 92.
- the intermediate portion 88 and the third transverse rib of the rear portion 92 allow to cash the axial forces caused by the support of the axis sections 58 on the two second half-bearings cylindrical 66.
- the third rib is intended here to rely on the front end of the stator 160 of the electric motor.
- Screws 104 are provided to assemble the cylinder head of the housing 15 to the nose 12 of the starter.
- the outer diameter of the second radial annular front face 21 of the electromagnetic actuator 14 is reduced compared to the state of the art of way that it corresponds to the inside diameter of the transverse crown 100.
- the axial thickness E of the transverse ring 100 is greater than the clearance maximum J2, shown in Figure 4, which exists after assembly of the starter 10, between the first 20 and the fourth 25 radial annular faces.
- the thickness E is slightly greater than the game maximum J2, all depending on the elasticity of the material used for the piece 82.
- the difference is for example 0.5mm to 2mm depending on the material of the crown 100.
- the metal / metal contact ensures a stable attachment of the contactor eliminating all the problems due to creep and elasticity of the support piece 82 of the actuating lever 40 that would exist if it was involved in the fixation of the actuator 14 and the starter nose 12.
- the return spring 156 and the movable core 151 of the actuator are not likely to so not to be reached by water coming from the outside so that a good sliding of the mobile core is assured.
- the number of pions depends on the applications, a pion 106 being at least planned.
- the diameter of the base of the positioning pins 106 is slightly greater than the diameter of the holes 108. This makes it possible to improve the sealing inside the electromagnetic actuator 14 provided by the crown annular 100.
- Means 110 for holding screws 104 are formed on the periphery of the transverse ring 100. They allow the passage and guiding of the screws
- the holding means 110 for the screws 104 are, for example, holes made directly in the transverse ring 100 or pairs of lips substantially parallel which extend radially to the transverse ring 100 according to the embodiment illustrated in Figure 3.
- a flare 114 is formed on a front portion of the radial annular face interior of the transverse ring 100.
- the flare 114 has a frustoconical shape which facilitates the mounting, in the electromagnetic actuator 14, of the mobile core and than the return spring surrounding it. Indeed, the conical shape increases the diameter wherein the free rear end of the movable core is to be introduced initially during its mounting in the electromagnetic actuator 14.
- the support piece 82 of the lever 40 comprising the annular ring 100 makes it possible to economically perform several functions which are: the articulation of the operating lever 40, the centering of the electromagnetic actuator 14, the indexing angular of the actuator 14, the seal between the starter nose 12 and the actuator electromagnetic system 14, guiding and holding the assembly screws 104 as well as the prepositioning the movable core and its return spring before assembly in the electromagnetic actuator 14.
- the support piece 82 of the actuating lever 40 according to the invention thus allows to facilitate the assembly of the starter 10 without increasing the number of pieces to assemble, nor the price of the starter 10.
- a continuous bead forming a closed line on each radial faces of the ring 100, bearing on the faces 21 and 25, makes it possible to limit the compression force exerted during the tightening by means of the screws 104 during the assembly of the actuator 14 on the starter.
- the piece 82 made of plastic is light and does not risk rust. This piece reduces friction at the lever joint actuator 40, itself made of plastic. Corrosion phenomena are therefore reduced.
- the piece 82 allows by its portion 88 to close sealing the local opening made at the rear of the nose 12 for the passage of the lever 40. This opening affects the faces 25,26 as visible in FIG.
- the piece 82 has another function because, thanks to its portion or rear portion 92, it closes tightly.an opening made in front of the casing 17, to avoid any movement of the room 82.
- the rear portion 92 is mounted, preferably by force, in the manner of a drawer in this opening.
- the ribs 94 are set back with respect to longitudinal side edges of the rear portion to obtain a good seal and easy assembly.
- the housing 17 has a front portion and a portion rear disposed on either side of the stator 160 closing the aforementioned opening. In variant this opening is closed by the housing itself then in one part.
- the pawns are worn centrally by ears 160.
