Definitions
- the invention relates to an electric starter for a combustion engine of a motor vehicle, said starter comprising:
- a launcher equipped with a pinion for driving a ring gear of the flywheel of the combustion engine, said pinion being able to slide axially on the output shaft between a rest position in which it is disengaged from the crown, and an active working position in which it meshes with said crown,
- a stop arranged on the output shaft to limit the stroke of the launcher in the active working position.
- a motor vehicle starter comprises in a conventional manner, a rotary electric motor 100 whose output shaft 12 is equipped with a movable pinion 14 intended to cooperate with a toothed crown 15 of the flywheel to ensure starting the combustion engine (not shown) of the vehicle.
- the pinion 14 is slidably mounted on the output shaft 12 between a rest position in which it is disengaged from the toothed ring, and an active working position in which it meshes with said ring, which is linked in rotation to the crankshaft of the vehicle combustion engine.
- the electric motor 100 of the starter is associated with a contactor CT with an electromagnet disposed above the electric motor 100, and having a double function of supplying the electric motor 100 with current, and of moving the movable pinion 14 between the two rest and work positions.
- the excitation of the electromagnet of the CT contactor is controlled by actuation of the ignition key, which establishes the electrical circuit towards the battery, following the closing of the main power contact CP of the contactor CT.
- the movable core 23 of the contactor CT is mechanically connected by a control lever 16 to a launcher 18 comprising the pinion 14 and a freewheel transmission device 20.
- the control lever 16 in the form of a fork is pivotally mounted on an axis 22, and the freewheel 20 is interposed axially between the pinion 14 and a drive hub 24, which is actuated by the control lever 16.
- the output shaft 12 is rotatably mounted in a casing 26 via a pair of bearings 28, 29.
- the drive hub 24 comprises two series of helical grooves of complementary shapes, arranged respectively on the output shaft 12, and in an internal cylindrical sleeve of the drive hub 24.
- the pinion 14 is thus secured to the drive hub 24 by the freewheel transmission device 20, which makes it possible to drive the pinion 14 in a direction of rotation corresponding to that of the output shaft 12 during the normal phase of starting, and disengaging the mechanical rotation drive link when the speed of rotation of the pinion 14 is greater than that of the drive hub 24.
- the presence of the freewheel transmission device 20 prevents the pinion 14 in engagement with the crown, driving the rotor of the electric motor 100 at an excessive speed liable to damage the latter. Such a situation can occur when the driver does not cut the power to the contactor immediately after starting.
- a stop 30 is arranged on the output shaft 12 on the side of the bearing 28 to limit the stroke of the starter 18 in the active working position when the pinion 14 drives the thermal engine in rotation. Stop 30 is axially immobilized on the shaft 12 by a rod 32 housed in an annular groove 34.
- the starter When the starter is energized, the pinion 14 is moved in translation by the lever 16 in the direction of the arrow F.
- the speed acquired by the launcher 18 is important. Due to this speed, the mass of the launcher 18, and the mechanical rigidity of the parts in contact, this results in an impact which results in a high instantaneous mechanical stress on the pinion 14 and the stopper 30, and in noise. brief but noticeable by the driver and those in the vicinity of the vehicle.
- the object of the invention is to reduce the noise of the starter at the end of engagement of the pinion in the drive ring of the heat engine.
- the device according to the invention is characterized in that the stop is composed of a metal ring and an elastic element, which is arranged to absorb the shock when the pinion comes into engagement.
- the material of the elastic element is chosen according to its elastic, damping and mechanical properties. The effect of such a shock absorber makes it possible to obtain a limitation of the compressive force due to the impact energy distributed over a greater duration than that generated with a conventional system where contact takes place metal on metal. This results in a reduction in noise emission during start-up.
- the elastic element has a shape of a circular torus with rectangular section, and constituted by a stud of elastomeric material fixed to the ring, said stud being deformable as the crushing under the thrust of the pinion.
- the elastic element comprises means for obtaining a stiffness that is higher the greater the crushing.
- the front surface is equipped for this purpose with projections intended to make the braking of the pinion more progressive.
- the ring of the stop can be provided with a protuberance oriented towards the pinion to limit the crushing of the damping pad
- the elastomer damping pad can be provided with a resistant element, for example a washer in treated steel against which the pinion comes into contact.
- FIG. 1 is a partial sectional view of a starter launcher of the prior art
- FIG. 2 shows a sectional view of the stop of the launcher according to the invention
- - Figure 3 shows an alternative embodiment of the damper associated with the stop of Figure 2
- - Figure 4 illustrates a diagram as a function of time of the compression force exerted by the pinion on the stop, respectively for a starter of the prior art (curve 1), and according to the invention (curve 2);
- FIG. 6 represents the diagram of the compression force exerted on the stop of FIG. 5.
- FIG. 8 is a schematic view of an embodiment of a starter ancestor associated with the contactor according to the invention.
- FIG. 11 is a front view of the elastic washer fitted to the launchers of FIGS. 9 and 10.
- the stop 30 is composed of a metal ring 31 and an elastic element 40, which is affixed against the bearing face 38 of the ring 31, to absorb the shock during the coming in engagement with the front face 36 of the pinion 14.
- the elastic element 40 has the shape of a circular torus with rectangular section, and is made of a material chosen according to its elastic properties, damping and mechanical strength.
- the damper In the case of a molded elastomer, it is advantageously possible to shape the damper to have a limited contact surface at the start of contact with the pinion 14.
- the elastomer is deformable as the element is crushed elastic 40 under the thrust of the pinion 14.
- the contact surface gradually increases, which makes the part more difficult to deform.
- the front surface 52 of the elastic element 40 is equipped with projections 42 to obtain a stiffness which is all the higher as the crushing is tall. This property makes the braking of the pinion 14 more progressive for a given crushing stroke, which reduces the shock points, and therefore the noise.
- the damping effect resulting from the presence of the elastic element 40 generates an instantaneous compression force whose tip is limited due to a shock energy spread over a longer period of time.
- the torque transmitted by the starter creates, via the helical splines of the starter 18, a contact force F e on the stopper 30.
- the contact takes place metal on metal, and there is a shock point F1p of duration t1 on curve 1.
- the point F2p on the curve 2 is less than F1p, and the duration t2 is greater than t1.
- the intensity of the shock is reduced, and it is spread over time, which is very favorable for reducing the sound emission.
- the ring 31 of the stop 30 is provided with a tubular protuberance 44 oriented towards the pinion 14, so as to delimit a toroidal housing 46 having a rectangular section ABED extending between the periphery of the shaft 12 and the internal wall of the protuberance 44.
- the damper 40 is formed by a stud of rectangular section DFCG, the volume of which is less than or equal to the volume of the housing 46 in the ring.
- the shock absorber 40 for example made of elastomer undergoes wear by friction on its contact face with the pinion 14 with risks of degradation of the damping effect.
- the damper 40 can be provided on its front face 52 with a resistant element 48 against which the pinion 14 comes into contact.
- the resistant element 48 consists, for example, of a washer made of treated steel.
- this resistant element 48 can be applied to the front face 52 of the damper 40, this front face being fitted or not with projections 42.
- the elastic element 40 can be assembled by gluing, clipping, stapling, crimping, or any other known means.
- the elastic element 40 can be mounted slightly tightened on the shaft 12, so as to remain linked in translation and rotation by its own elasticity, thus preventing any movement caused by the vibrations of the heat engine.
- the elastic element 40 may consist of a metal washer with elastic deformation, in particular a Grower washer, a conical washer, a compacted block of braided stainless steel wires, etc.
- the freewheel device 20 is of the type comprising rollers known in a conventional manner.
- the pinion 14 reaches the end of travel against the stop 30, this results in a shock which results in a high instantaneous mechanical stress on the pinion 14 and the stop 30.
- this shock is reduced by the presence of 'a damping element 40 as described above.
- the freewheel is of the type comprising rollers there is also a radial damping component resulting from the radial deformation of the elastic bell 50 under the radial pressure of the rollers as soon as the pinion comes into abutment.

- the elastic means 10 are carried by the skirt 1b (FIG. 9) or 12b (FIG. 10) of the part hitch .
- This skirt on the one hand, internally carries one of the first and second surfaces 8, 8 ′ and, on the other hand, is, via the bottom of the coupling piece, secured to one of the pinion elements 14 - launcher 24, which is associated with the surface 8, 8 ′ carried internally by the skirt, more precisely by the internal periphery thereof.
- a groove 51 is provided to cooperate with the control lever 16 in the form of a fork.
- the contact diameter of the first surface 8 with the second surface 8 ' is greater than the diameter of the head circle of the teeth of the pinion.
- the first or second surface 8, 8 'carried by the skirt 1b, 12b is axially longer than the other second or first surface 8', 8.
- the elastic means 10 are carried by the free end of the skirt 1b, 12b and extend in axial projection relative to said other second or first surface 8 ', 8.
- the transverse shoulder is extended at its internal periphery by an annular bearing 4 "generally of axial orientation delimiting with said shoulder a removal of material to accommodate at least partially the elastic means with axial action 10.
- the elastic means with axial action here have the form of a circlip and are received in a groove produced at the internal periphery of the free end of the skirt.

- the washer 10a has a radial slot 10g symmetrically affecting one of the two rooting zones 10d; four arms 10b being provided at the rate of two arms per zone 10b.
- the first stop is formed by means of a circlip or a stop ring mounted in a groove produced at the internal periphery of the free end of the skirt.
- the elastic means 10 can then consist of at least one Belleville washer or at least one wavy washer see a frustoconical coil spring bearing on the circlip or the ring for action on the driver (figure 9) or on the pinion (figure 10) for controlled tightening of surfaces 8 , 8 '.
- the first stop is attached to the free end of the skirt.

- the coach is in an embodiment obtained by molding, for example being made of plastic.
- molding for example being made of plastic.
- FIG. 8 we see the decomposition of the forces when the pinion 14 is in contact with the working stop 30.
- the initial pressure of the elastic means between the stops produces a friction torque between the driver and the pinion which is always, by construction, greater than the torque necessary for screwing and advancing the launcher on the shaft 12. This condition allows the self-priming movement of the launcher between its rest position and its advanced position against the working stop 30 at the start of the vehicle engine drive phase via the starter ring.
- This blocking of movement between the pinion and the driver depends in particular on the angles and diameters of the frustoconical friction surfaces.
- This force Fa is itself decomposed at the frustoconical friction surfaces to create a normal contact force Fc, which generates a tangential force Ft at the frustoconical surfaces 8, 8 ′ as a function of the coefficient of friction between these surfaces.
- the value of this force Ft multiplied by the average contact radius of the frustoconical friction surfaces determines the torque Ce transmitted by the conical clutch 7.
- the coefficient of proportionality between Fa and Fc depends on the angle of the cone between the two frustoconical friction surfaces.
- Ft is related to Fc and to the coefficient of friction fc between the two materials of the frustoconical friction surfaces of the clutch 7.
- a is the value of the half-angle at the top of the cone of contact between the frustoconical friction surfaces and fc the coefficient of adhesion.
- the freewheel with a conical clutch does not have its own damping means.
- the axial impact is therefore more violent than with a launcher provided with a free wheel with rollers.
- a damping element 40 according to the invention as described above according to any one of these possible variants and, as visible for example in FIG. 10, will therefore find a very particular advantage in being implemented in a motor vehicle starter comprising a launcher with a conical clutch. This combination thus makes it possible to obtain an economical, light, silent and robust starter thanks to the reduction of mechanical stresses.
