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.
- a shoulder generates shocks and therefore significant internal stresses when the launcher passes into the active position so that the invention is particularly suitable to be implemented with this so-called "stop on groove” launcher configuration.
- the starter 10 comprises a drive shaft 11, a launcher 12 mounted on the drive shaft 11 and comprising a drive pinion 15.
- an electric motor 16 comprises a stator 17 inductor and an induced rotor 18 mounted coaxially.
- the stator 17 surrounds the rotor 18, which is mounted on a shaft 19 of the electric motor 16.
- the rotor 18 is capable of rotating around an axis metal support 23 of the starter 10 intended to be fixed on a fixed part of the motor vehicle.
- the stator 17 comprises a plurality of magnetic inductor poles 26 carried by the internal periphery of the yoke 21.
- the stator 17 comprises an inductor winding comprising two pairs of windings which are each wound around a polar mass secured to the yoke 21.
- 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.
- the axis of the shaft 19 coincides with the axis connected by tie rods to the support 23 of the starter 10.
- the metal cylinder head 21 is clamped between the metal support 23 and the metal rear flange 39.
- the starter 10 also includes an electromagnetic contactor 46 extending parallel to the electric motor 16 while being located radially above it.
- the contactor 46 has a metal tank 47 carried by the support 23, and equipped with an excitation coil 48 provided with at least one winding.
- the tank 47 is closed at the rear by a cover 49 made of electrically insulating material.
- the cover 49 is fixed by folding down the material from the free end of the tank 47.
- Terminals 50, 51 are shaped to each form a fixed contact inside the cover 49.
- One of the terminals 50 is intended to be connected to the positive terminal of the battery, the other terminal 51 is connected by the intermediate of a cable with brushes 34 of positive polarities.
- a mobile core 54 is attracted by magnetic attraction towards the fixed core 55 to, on the one hand, act after taking up a play on a rod 56 carrying a contact mobile 57 to cause the contacts 50, 51 of the contactor 46 to close and power the electric motor 16 of the starter 10, and, on the other hand, actuate a control lever 58 of the launcher 12.
- the drive shaft 11 is rotatably mounted in a front bearing 61 of the support 23 via a pinion carrier 62.
- This front bearing 61 making it possible to guide the drive shaft 11 in rotation is constituted as for example by a ball bearing.
- the pinion carrier 62 comprises a hollow shaft 63 to allow the passage of the drive shaft 11.
- Two bearings 64 are interposed between the external periphery of the drive shaft 11 and the internal periphery of the carrier shaft.
- pinion 63 to allow relative rotational movement between the two elements 11, 63.
- the external periphery of the pinion-carrying shaft 63 is in contact with the internal periphery of the front bearing 61.
- the drive pinion 15 is mounted integrally in rotation with the pinion-carrying shaft 63 via axial splines made in the internal periphery of the pinion engaging with axial splines of complementary shape made in the external periphery of the pinion. pinion carrier shaft 63.
- 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.
- This free wheel 73 comprises a driven ring 76 located on the side of the rear end of the pinion carrier shaft 63.
- the driven ring 76 has on its outer periphery an internal track 77 clearly visible in figure 4 .
- the driven ring 76 is in one piece of same material with the pinion carrier shaft 63.
- the driver 72 comprises a driving ring 78 of the free wheel 73 provided with ramps 79 on its internal periphery.
- the driving ring 78 is thus integral in rotation with the shaft 11 via the driver 72 when the launcher 12 is in the active position.
- a plurality of Y-axis rollers 82 are mounted between the internal track 77 and a corresponding ramp 79.
- 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. In the active position, the driver 72 abuts against a shoulder 93 made between the teeth 91 of the drive shaft 11. This shoulder 93 of the drive shaft 11 is located axially between the base plate 106 and the front bearing 61.
- a speed reducer 96 taking the form of an epicyclic gear train is mounted between the rotor shaft 18 and the drive shaft 11. More precisely, the rear end of the drive shaft 11 is configured to be secured to a plate of a satellite carrier 97 for example by crimping. Satellites 101 mesh on the one hand with a ring gear 102 forming an external planetary gear and on the other hand with a pinion 103 secured to the front end of the rotor shaft 19 forming an internal planetary gear 96. The satellites 101 are mounted free in rotation each around an axis carried by the satellite carrier 97. The satellites 101 are at least two in number. In this case, three satellites 101 are used.
- the crown 102 is carried by a base plate 106 shown in detail on the figure 2b secured to the cylinder head 21 of the engine by clamping between said cylinder head 21 and the support 23 of the starter 10.
- the base plate 106 comprises a metal plate 107, a bearing 108 mounted on the shaft drive shaft 11 to guide the drive shaft 11 in rotation, as well as a plastic portion 109 overmolded on the plate 107 and the bearing 108 to make them integral with each other.
- the plastic portion 109 comprises a layer of plastic 112 between an external periphery of the bearing 108 and an internal periphery of the plate 107 corresponding to an edge of the plate 107 delimiting a central opening 116 for the passage of the shaft 11.
- a layer 112 clearly visible on the figure 2c makes it possible to support the angle taken by the bearing 108 generated by the bending of the shaft 11 in order to limit excess edge pressure.
- the thickness E of this plastic layer 112 is at least 0.5mm. In order to minimize the pressure exerted by the drive shaft 11, it is possible to use a bearing 108 having an axial length greater than 5mm.
- the metal plate 107 comprises a main portion 114 and a shoulder 115 extending axially relative to the main portion 114 on one end of the plate 107 located on the side of the pad 108.
- the shoulder 115 is thus located on the internal periphery of the plate 107 around the central opening 116 of the plate 107, while the main portion 114 extends from the shoulder 115 to the external periphery of the plate 107.
- the pad 107 thus has an extra thickness at the end located on the side of the pad 108.
- the pad 108 has an axial length L1 greater than the axial thickness L2 of the main portion 114 of the pad 107.
- the plastic portion 109 comprises at least two stop parts 120 mounted between the crown 102 and the cylinder head 21. These stop parts 120 extending circumferentially around the crown 102 make it possible to hold the crown 102 radially in the cylinder head 21.
- the crown 102 attached to the base plate 106 comprises projections 121 extending from an external periphery of said crown 102. Damping pads 122 are mounted between the projections 121 of the crown 102 and the stop parts 120 of the plastic portion 109. Such a configuration makes it possible to absorb the shocks suffered by the crown 102 made for example of metal.
- the crown 102 is part of the plastic portion 109.
- the teeth of the crown 102 are molded with an axial annular wall of the plastic portion 109.
- a holding element 125 taking for example the form of a circlip type elastic stop ring is positioned in a groove 126 of the drive shaft 11 to abut against the base plate 106 (cf. figure 2a ).
- the elastic stop ring 125 has the shape of an open ring capable of being elastically deformed using a tool to allow its positioning inside the groove 126.
- the circlips 125 rests against a metal support washer 141 which rests against the plastic portion 109 of the base plate 108.
- the elastic stop ring 125 includes traces of impact 133 of prestressing shot peening on at least its radial face located opposite the base plate 106. To prevent the elastic stop ring 125 is deformed in the prestressed state, the prestress shot peening impact traces are located on the side of the two radial faces of the elastic stop ring 125.
- the prestressing shot peening applied to the elastic stop ring 125 should be distinguished from the cleaning or deburring shot peening implemented at the end of the manufacturing process and which does not make it possible to obtain compressive stresses between - 600 and -1000 MPa.
- the impact intensity of the media is thus much greater in the case of prestressing shot peening than in the case of cleaning shot peening.
- the invention makes it possible to greatly improve the fatigue resistance of the elastic stop ring 125.
- the elastic stop ring 125 is made of steel and has undergone a bainitic quenching treatment.
- the thickness of the elastic stop ring 125 is for example of the order of 2mm plus or minus 10%.
