Definitions
- the invention relates to a double damping flywheel, particularly for a motor vehicle, comprising two masses of inertia movable in rotation about the same axis and connected by a torsion damper comprising spring means and an epicyclic gear train.
- a double damping flywheel of this type is already known, in particular from document FR-A-2714131 which describes a double damping flywheel whose torsion damper comprises an epicyclic gear train.
- the sun gear is rotated by a first mass of inertia integral with the crankshaft of an internal combustion engine, the ring is secured to the second mass of inertia and coil springs. are mounted in a chamber delimited by the first mass of inertia, either between this first mass of inertia and the planet carrier, or between the first mass of inertia and the crown, or between the crown and the planet carrier.
- An advantage of using an epicyclic gear train in the torsion damper of a double damping flywheel is to allow the transmission of a torque between the two masses of inertia with a transmission ratio determined by the epicyclic gear train.
- the embodiments described in document FR-A-2714131 have the disadvantage, however, that the springs of this torsion damper, which are rotated with the masses of inertia and which are located at the outer periphery of these masses of inertia , are very sensitive to centrifugal forces and have a hysteresis which becomes important when the speed of rotation increases, with the risk of blockage and jolting operation.
- the present invention is intended to avoid these disadvantages of the prior art. It proposes for this purpose a double damping flywheel of the aforementioned type, comprising two masses of inertia movable in rotation about the same axis and connected by a torsion damper comprising spring means and an epicyclic gear train consisting of three elements comprising a sun gear, an outer ring gear and a planet carrier whose gears are engaged with the sun gear and with the ring gear, characterized in that the spring means are arranged in a fixed frame and associated with one of the three elements of the epicyclic gear.
- An essential advantage of the double damping flywheel according to the invention is that the spring means of the torsion damper are not rotated with the masses of inertia and are therefore not subject to centrifugal forces in operation.
- the spring means are supported on the one hand on the element of the epicyclic gear and on the other hand on the fixed frame, the rotation of this element relative to the fixed frame being limited by the means to spring.
- the spring means comprise a helical spring which is mounted in the fixed frame around said element and which extends at rest about 360 ° about the axis of rotation of the masses of 'inertia.
- the angular displacement of said element can reach 120 ° on either side of a rest position, the angular clearance allowed between the two masses of inertia being a function of the transmission ratio of the epicyclic gear and which can be example of 80 ° on either side of a rest position, when the transmission ratio of the epicyclic gear is 1, 5, which corresponds to much higher performance than the current damping double flywheels.
- the spring means of the torsion damper comprises a plurality of springs mounted end to end through 360 ° in the fixed frame.
- the spring or springs of the torsion damper may be curved springs in the free state, to facilitate their mounting in the fixed frame.
- this double damping flywheel comprises a pre-damper which is arranged between the primary mass of inertia and the element of the epicyclic gear which is connected to this primary mass of inertia.
- the double damping flywheel according to the invention can be mounted in a conventional manner in a motor vehicle, between the internal combustion engine and a gearbox, it can also be included in the internal combustion engine, in whole or in part, this which has the advantage of ensuring the lubrication of the pinions of the epicyclic train by the lubricating oil of the engine.
- Another advantage of the double damping flywheel according to the invention is to allow to pass without problem the resonant frequency at start and stop of the engine, by blocking the mass of secondary inertia relative to the mass of primary inertia, this can be done very simply by blocking the epicyclic gear element on the fixed frame.
- FIG. 1 is a simplified schematic view of a double damping flywheel according to the invention
- - Figure 2 is a front view of the torsion damper of this double damping flywheel, in a rest position;
- Figures 3 and 4 are views similar to Figure 2, showing the torsion damper in two different operating positions;
- the double damping flywheel shown diagrammatically in FIG. 1 comprises a primary inertia mass 10 fixed at the end of a driving shaft 12 such as the crankshaft of an internal combustion engine M, and a secondary mass of inertia 14 which is coaxial to the primary mass of inertia 10 and which is for example connected by a clutch E to the input shaft of a gearbox BV, the two masses of inertia 10, 14 being connected one to the other in rotation by a pre-damper 16 and a torsion damper 18.
- the torsion damper 18 comprises an epicyclic gear train consisting of a sun gear 20, an outer ring 22 and a planet carrier 24 whose gears 25 are engaged with a toothing external of the sun gear 20 and with an internal toothing of the ring gear 22.
- the pre-damper 16 which is of a conventional type, is mounted between the primary mass of inertia 10 and the planet carrier 24.
- the axis of the sun gear 20 is integral with the secondary mass of inertia 14 which can be centered and guided in rotation in conventional manner on the primary mass of inertia 10.
- the outer ring 22 is guided in rotation in a fixed frame 26 which surrounds the epicyclic gear.
- the torsion damper 18 also comprises, in this example, a coil coil spring 28 which surrounds the outer ring of the epicyclic gear train and which extends approximately 360 ° about the axis of rotation of the double damping flywheel, this spring 28 being for example housed and guided in an annular chamber of the fixed frame 26.
- the ends of the spring 28 are supported on the one hand on a radial tab 30 of the fixed frame 26 and on the other hand on a radial tab 32 of the outer ring 22, the radial tab 30 of the frame 26 extending inwardly. while the radial tab 32 of the ring 22 extends outwardly.
- the radial tab 32 of the ring 22 can extend in a diametral plane of the end turns of the spring 28, while the frame 26 then has two radial tabs 30 which extend from both sides. other of the diametral tab 32 of the ring 22, as is often provided in the circumferential spring torsion dampers.
- the spring 28 of the torsion damper may be curved in the free state, to facilitate its implementation around the ring 22.
- it may be a free spring in the free state, that it is curved for its mounting around the crown 22.
- the spring 28 may be replaced by two or more springs mounted end to end, these springs being curved or rectilinear in the free state.
- vibrations and rotational acyclisms are absorbed and damped by the pre-damper 16, while the spring 28 of the torsion damper 18 remains in the state shown in FIG. 2, where it extends about 360 ° around the ring 22, both ends bearing on the radial tab 30 of the fixed frame and on the radial tab 32 of the ring 22.
- the rotation of the ring 22 relative to the fixed frame 26 is for example about 120 °.
- the corresponding rotation of the secondary inertia mass with respect to the primary inertia mass is determined by the transmission ratio of the epicyclic gear train. If this ratio is for example 1, 5 (which means that the rotational speed of the secondary mass of inertia 14 is equal to 1, 5 times the speed of rotation of the primary mass of inertia 10), the deflection maximum possible angularity of the secondary mass of inertia 14 relative to the primary mass of inertia 10 is 80 ° on either side of a median position when the angular displacement of the ring 22 relative to the fixed frame is 120 ° on both sides of a median position.
- the damping performance of the vibrations that result are much greater than those of a classic double damping flywheel.
- the passage through the resonance frequency which is a problem that is encountered in all the double damping flywheels at stopping and starting the vehicle engine, can be solved in a very simple way in the double damping flywheel according to the invention, either by locking in rotation of the outer ring 22, or by release of this outer ring, the secondary mass of inertia then being either locked in rotation relative to the primary mass of inertia, or free in rotation with respect to this mass of primary inertia at the passage by the resonance frequency.
- the locking of the outer ring 22 can be done by blocking its radial lug 32 or by applying a brake pad on the outer ring. Its release in rotation is achievable in a simple way by removing the radial tab 30 of the fixed frame passing through the resonant frequency.
- the epicyclic gear train of the torsion damper When the double damping flywheel according to the invention is mounted in a conventional manner in a motor vehicle between the engine and the gearbox, the epicyclic gear train of the torsion damper must be housed in a sealed chamber containing a lubricating liquid.
- this sealed chamber is no longer necessary and the lubrication of the components of the epicyclic gear is ensured directly by the oil engine.
- an electrorheological or magnetorheological fluid as dissipative energy element, these fluids being suspensions of solid particles whose mechanical properties are adjustable by an external field. electric or magnetic.
- the primary mass of inertia 10 is integral in rotation with the ring gear 22, and the planet carrier
- FIG. 1 This embodiment differs from that of FIG. 1 in that the connections of the primary mass 10 and the chassis to the planet carrier and to the ring gear are reversed, the secondary mass of inertia 14 remaining connected to the sun gear 20.
- Figure 6 the embodiment of Figure 5, which has been added a second stage of planet gears 25 '. The planet gears 25 of the first stage are engaged with the crown 22 and the satellite gears
- This double stage of satellite gears offers greater freedom in the choice of transmission ratios of the epicyclic gear train, for a low radial size.
- the directions of rotation of the input and the output of the epicyclic gear train are reversed.
- Figure 7 shows the device of Figure 6 with a modification of the contacts of the ring gear 22 and the planet gears 25 from the outside to the inside of the planet gears. This arrangement has the advantage that the directions of rotation of the input and the output of the epicyclic gear train are the same.
- the device represented in FIG. 8 is that of FIG. 1 with the addition of a second stage of planet gears 25 'as in FIG. 6.
- the directions of rotation of the input and of the output of the train are identical.
- the choice of transmission ratios of the train is wider, for a small radial size.
- the masses of inertia are interchangeable, that is to say that the primary mass of inertia 10 can be linked to the sun gear 20 and the secondary mass of inertia 14 can be linked to the ring 22 or the planet carrier 24.
