Definitions
- the present invention relates to starters, for heat engines, in particular for motor vehicles, provided with a toothed launching wheel, of the type comprising an electric motor, a launcher carrying a pinion for driving the gear wheel of the motor in rotation thermal and movable on an integral output shaft in rotation of the electric motor shaft between a passive position in which the pinion does not mesh the gear wheel and the motor is not energized, and a active position in which the pinion meshes with the gear wheel and in which the motor is energized; the launcher comprising a coaxial and linked entry part in rotation at the output shaft of longitudinal axis X-X, an output part linked in rotation to the pinion, and a device for rotating the two parts.
- Starters of this type are known in the art earlier for example by documents FR A 2 772 473 and FR A 2 795 884. It turned out that the organs mechanical of the launcher and more generally of the starter are shocked during the start-up phase of the thermal motor. Axial shocks when the launcher is moved against the gear wheel of the engine, torsional shocks when the pinion meshes with the wheel toothed. These shocks are sizing for design pinion, and can also cause wear of mechanical parts of the launcher and more generally of the starter.
- disengageable coupling devices comprising a bell driven in rotation by the entry part, a tubular shaft constituting a end of the outlet part and whose surface exterior defines a track, and organs one-way coupling linking the track to the bell for the transmission of the torque oriented along a first direction, and allowing the bell to rotate freely relative to the track when the torque is oriented in opposite direction.
- organs are pebbles, typically linked to springs and arranged in housings of adapted forms practiced in the bell.
- the disengageable coupling device comprises a conical clutch with a friction surface frustoconical carried by the output part and cooperating with a complementary frustoconical friction surface carried by the entry part. It is important to spare these frustoconical friction surfaces.
- the coupling device includes two parts secured in rotation by the damping means.
- the object of the present invention is not to increase the radial size of the coupling device while providing it with a means of amortizing at least torsional shocks.
- a starter of the above-mentioned type comprising a coupling device in rotation of the input and output parts including an upstream coupling part belonging to the part input, a downstream coupling part belonging to the output part and a means of damping mechanical shock, at least torsional, in which the inlet part includes a tubular inlet sleeve linked in rotation to the output shaft, is characterized by that the entry part includes a linked coach rigidly to the tubular inlet sleeve, in that the upstream coupling part has a crown coaxial with the output shaft, in that the downstream part coupling extends coaxially with respect to the crown and in that the crown and the coach are secured in rotation by the damping means.
- the radial size of the launcher is not increased and the bell is split into two elements namely the coach and the crown between which intervene circumferentially the means coupling placed axially between the crown and the coach.
- the coupling device is of the type pebbles, each of which is engaged between a portion of track of the upstream coupling part and a portion track of the downstream coupling part; the part downstream coupling, cylindrical in shape, extending coaxially in said crown.
- the coach comprises a base having substantially the shape of a disc coaxial with the shaft of exit and leading reliefs on the face of the base oriented towards the pinion extending both along a radial direction and in an axial direction, the crown with led reliefs oriented towards leading reliefs extending both along a radial direction and in an axial direction, the damping means comprising a plurality damping elements, each damping element being disposed between a leading relief and a led relief.
- leading and led reliefs are distributed angularly equidistant on their support surface in a circle centered on the axis of this last, the reliefs led being in number equal to number of leading reliefs.
- the damping elements are grouped by pairs which each form a set in which the two damping elements are connected by an element of bond so that a notch is formed between them, a leading relief or a led relief being engaged in the notch.
- the section of each relief leading or led in a plane perpendicular to the longitudinal axis X-X adopts the shape of a radial tab having two rectilinear side faces converging towards the axis longitudinal X-X.
- each connecting element contributes to absorb shocks in the axial direction.
- the crown and the organ of the part of exit delimit between them tangential housings having an evolving radial width, in a first direction of rotation, between a minimum width and a maximum width, and in that a pre-stressed spring in compression and a roller stressed by the spring in direction of the minimum width of the housing are arranged in each housing, the crown carrying substantially radial internal ribs separating two adjacent dwellings on each of which is supported one of the springs, and in that the leds are the axial extension of these internal grooves.
- a washer is interposed between the means cushioning and rollers to avoid axial displacements of the rollers caused by the deformation of the damping means.
- a motor vehicle includes a heat engine, which for its start-up, has a toothed launch or starter wheel (not shown) intended to be rotated by the pinion of a starter.
- This starter includes essentially an electric motor 1 whose shaft motor 2 rotates around an axis X-X un output shaft 2 'axially aligned on shaft 2, a launcher 3 axially sliding on the shaft 2 'but integral in rotation with the latter and carrying a pinion 5 in rotation of the launch wheel toothed, and a pivoting fork 4 moving the launcher 3 axially on the shaft 2 ', between a position passive rest and an active position of engagement.
- a train speed reducer of planetary gear intervenes in a known manner between the two trees 2, 2 '.
- the two trees 2 and 2 ' are confused.
- the tree of output is integral in rotation with the motor shaft electric, constituting the armature shaft thereof. All of these elements are enclosed in a casing 6 serving as support for an electromagnetic contactor (not shown) extending parallel to the motor electric.
- the casing 6 is also used for fixing the starter on a fixed part of the motor vehicle.
- the radial size of the casing 6 is not changed thanks to the characteristics of the invention described below.
- the contactor is described for example in the document FR A 2 795 884, to which reference will be made for more details, and therefore includes a coil connected to the motor vehicle start switch, a moving core, a fixed core, a moving contact and springs.
- the fork is connected, here via a spring, to the moving core.
- This moving core when the coil is activated after closing the switch startup, moves to act on a mobile contact intended to come into contact with studs, one of which is connected to the positive terminal of the vehicle battery and the other to the electric motor 1, for power electric motor 1.
- the moving core rotates the fork 4, which moves the launcher 3.
- pinion 5 mounted at one end of the starter 3, engages the engine launch wheel thermal to start this one and comes in contact with a stop (not referenced) carried by the end of the output shaft 2 '.
- the launcher 3 comprises, on the one hand, a part input 7, linked in rotation to the shaft 2 'by a connection with complementary helical splines intervening locally between the internal periphery of the input part 7 and the outer periphery of the shaft 2 ', and, on the other hand, an outlet part 8 comprising the pinion 5.
- the invention relates essentially to the launcher 3 crossed by the output shaft 2 ', which will be described below with reference to Figures 2 to 8.
- the inlet part 7 comprises, axially aligned on the axis XX, a tubular inlet shaft segment 10, constituting a tubular inlet sleeve of axial orientation, carrying a fork guide 11 in the form of a gutter or annular groove, in which the end 4 ′ for controlling the fork 4 is engaged, and an upstream coupling part 12.
- the tubular sleeve 10 has internally internally at its internal periphery the abovementioned helical grooves for engaging in a complementary manner with the helical grooves that presents locally at its external periphery the output shaft 2 'so that the sleeve 10 is linked in rotation to the output shaft 2' but can move axially relative to the latter.
- the outlet part 8 essentially consists of a tubular outlet shaft segment 13, constituting an axially oriented tubular outlet sleeve, carrying the pinion 5 at its front end 14 and a downstream coupling part 15 at its rear end 16.
- the disengageable coupling device 9 is as in Figure 1 of the roller type.
- the pebbles bear the reference 22.
- the upstream coupling part 12 comprises according to a characteristic of the invention, a trainer 17, of transverse orientation, integral of the inlet sleeve 10, a crown 18, of orientation axial, movable relative to the coach 17, a cover 19 of assembly of hollow form linking one to the other the coach 17 and the crown 18 in translation axial.
- a damping means 20 is placed axially between the coach 17 and the crown 18 and ensures the connection rotating between them. So the depreciation means 20 intervenes axially and circumferentially between the crown 18 and the coach 17 rigidly connected to the sleeve input 10.
- This damping means is circumferentially elastic so that the crown 18 and the coach 17 belong to a shock absorber of circumferential twist.
- the downstream coupling part 15 consists by the rear end 16 of the output shaft 13, which has a cylindrical outer surface defining a track 21 for the rollers 22 which are interposed between this track 21 and the internal surface of the crown 18 as will be explained below.
- the rear end 16 is of a diameter slightly higher than the rest of the tree 13. The downstream part coupling 15 is engaged coaxially in the movable crown 18.
- the coach 17 comprises a base 25 having substantially the shape of a disc coaxial with the axis X-X and having a front face 26 oriented towards the pinion 5.
- Coach 17 belongs to a torsional damper comprising the means 20.
- the crown 18 has a double function because it belongs to the coupling device 9 and cooperates with the depreciation means by belonging to a circumferential action torsional damper.
- the crown 18 has substantially the shape of a cylinder coaxial with the axis X-X, having a wall of a certain radial thickness and having a face rear frontal 28 oriented towards the base 25.
- Des led reliefs 29 extending both along a radial direction and in an axial direction do protrusions on the face 28 of the crown 18.
- the diameter outside of the crown 18 is substantially the same as that of the base 25 of the coach 17.
- leading reliefs 27 and led 29 are preferably distributed angularly equidistant on their support surface in a circle centered on the axis of the latter.
- the reliefs led 29 are in number equal to the number of leading reliefs 27.
- the damping means 20 comprises a plurality damping elements 30, typically blocks, which are each arranged in a plane perpendicular to the X-X axis, between a leading relief 27 and a led relief 29, as illustrated in FIG. 3.
- the elements shock absorbers 30 are grouped in pairs which form each a set in which the two elements 30 are connected by a connecting element 31 in such a way a notch 32 is formed between them.
- the driving reliefs 27 each engage in a notch 32, so that that these leading reliefs 27 are capped by the connecting elements 31 which separate them from the crown 18.
- the reliefs 29 are inserted between each pair of damping elements 30.
- each relief leading 27 or led 29 in a plane perpendicular to the longitudinal axis X-X preferably adopts the shape of a radial tab having two straight side faces converging towards the longitudinal axis X-X.
- the legs extend to from the peripheral surface of base 25 and the crown 18.
- the damping elements 30 are elastic and made of elastomer, for example rubber or in a suitable synthetic elastic material.
- the damping elements are metallic and for example have an accordion shape.
- the reliefs led 29 are separated from the base 25 of the coach 17 by a game J.
- the cover 19 covers the assembly consisting of the coach 17, the damping means 20 and the crown 18 radially and in both directions Axial. In addition to the functions described above, it also ensures the connection in axial translation between the crown 18 and the outlet part 8.
- the cover 19 consists of a thin cylindrical wall of axis X-X, the two axial faces being partially closed by thin walls substantially disc-shaped hollowed out in their centers.
- the crown 18 and the runway 21 delimit accommodation between them tangentials 24 having an evolving radial width, in the direction of rotation R, between a minimum width and a maximum width.
- a spring 23 prestressed in compression and a roller 22 coaxial with the crown 18 are arranged in each housing 24.
- the crown 18 carries radial internal ribs 34 separating two adjacent housing 24, the spring 23 being supported by a side on a rib 34, and the roller 22 being biased by the spring 23 towards the minimum width of the housing 24.
- the roller 22 rolls on runway 21 and on the bottom of the housing 24 facing it, in the opposite direction to R and comes to wedge in the zone of minimum width of the housing 24. The roller 22 then prevents the track 21 and the crown 18 to move relative to one another, and therefore ensures the transmission of torque.
- a washer 33 of axis X-X is interposed between the damping means 20 and the crown 18 so as to separate the damping means 20 of the rollers 22 to avoid axial displacements of the rollers 22 caused by the deformation of the means damping 20.
- the outer edge of the washer 33 is cut to fit the shape of the reliefs conducted 29.
- the connecting elements 31 and the damping elements 30 absorb part of the energy transmitted between the crown 18 and the coach 17 by deformation.
- Game J is sized in such a way so that the deformation of the connecting elements 31 and damping elements 30 do not cause contacts between the reliefs led 29 and the base 25 of the coach 17.
- the connecting elements 31 contribute to absorb the axial shock.
- an upstream coupling part 12 consisting of a crown 18 integral with a coach 17, rigidly connected to the sleeve 10, via damping means 20, instead of a bell in ancient art, has the advantage of allow a slight deformation of the upstream part coupling 12 without the axis of the crown 18 not be modified, the deformation being absorbed by the means damping 20, which prevents the rollers 22 are cantilevered from runway 21 and the bottom of housing 24 and therefore limits the risks flaking.
- Figures 7 and 8 illustrate a second mode of realization of the invention in which the reliefs led 29 are constituted by the extension in the axial direction of the ribs 34.
- the reliefs led 29 therefore do not extend radially to the periphery of the crown 18.
- the crown 18 extends radially to the front face of base 25.
- leading reliefs 27 are complementary to those of the reliefs led, the leading reliefs 27 fitting between the led reliefs 29, inside the crown 18, and the elements shock absorbers 30 also being arranged inside of the crown 18, each between a relief leading 27 and a led relief 29.
- This second embodiment allows a simpler and less costly crown manufacturing 18.
- the coupling device disengageable is of the conical clutch type the crown 18 carrying on its internal or external periphery a surface frustoconical friction suitable for cooperating so complementary with a friction surface frustoconical carried by the rear end 16 of the downstream part 15.
- the coupling device disengageable is of the conical clutch type the crown 18 carrying on its internal or external periphery a surface frustoconical friction suitable for cooperating so complementary with a friction surface frustoconical carried by the rear end 16 of the downstream part 15.
- downstream coupling part extends coaxially with respect to the crown This downstream part enters the crown or alternatively surrounds the crown when the coupling device has a conical clutch with a surface of friction of the type of that of FIGS. 3 and 8 of the document PCT / FR 02/02160.
- the downstream part enters the crown connected to the coach by the damping means.
