    The present invention relates to hydraulic antivibration devices.
    More particularly, the invention relates to a hydraulic anti-vibration device intended to be interposed for the purpose of damping between first and second rigid elements, this anti-vibration device comprising:

    FIG. 10 is a block diagram of the electronic circuit equipping the antivibration device of FIG. 1,
    - And Figure 11 is a block diagram similar to that of Figure 10, in a second embodiment of the invention.
    In the various figures, the same references designate identical or similar elements.
    Figures 1 to 4 show a hydraulic anti-vibration device 1, comprising:
    a first rigid frame 2 having for example the shape of a metal base and intended to be fixed in particular to the engine of a vehicle to support it,
    a second rigid frame 3, for example an annular frame made of metal or plastic, which is intended to be fixed for example to the body of the vehicle,
    an elastomer body 4 capable of withstanding in particular the static forces due to the weight of the vehicle engine and connecting the first and second armatures 2, 3, this elastomer body possibly having for example a bell shape which extends axially along a axis Z0, for example vertical, between an adhered and overmolded top on the first frame 2 and an annular overmolded and adhered base on the second frame 3.
    The antivibration device 1 further comprises a rigid partition 5 radial with respect to the axis Z0, secured to the second frame 3 and applied in leaktight manner against the base of the elastomer body.
    The rigid partition 5 delimits with the elastomer body 4 a first hydraulic chamber A, in this case a working chamber. The working chamber A communicates by a throttled passage C with a second hydraulic chamber B, in this case a compensation chamber, partially delimited by a deformable wall, in particular a flexible elastomer membrane 6 forming a bellows. The working chamber A, the compensation chamber B and the constricted passage C together form a hydraulic circuit filled with liquid, in particular glycol or the like.
    The constricted passage C is dimensioned to have a resonant frequency of, for example, between 5 and 20 Hz, typically between 8 and 12 Hz, corresponding to hash movements due to the running of the vehicle.
    Furthermore, the anti-vibration device further comprises a housing 7, which is integral with the second frame 3 and extends opposite the first frame 2 from the second frame 3.
    The housing 7 may possibly be made of plastic, in particular molded material.
    The box 7 can be produced in two parts:
    a main part comprising an annular side wall 10 extending axially along the axis Z0 between a first end close to the first frame and a second open end remote from the second frame,
    - And a bottom 8 closing the second end of the annular wall 10.
    The first end of the annular wall 10 is secured to the second frame 3 for example by clipping, or by any other known means. An annular seal 4a can be interposed between the first end of the side wall 10 and the second frame 3. This seal 4a can advantageously be formed by a part of the base of the elastomer body 4.
    The second end of the annular wall 10 is secured to the bottom 8 for example by clipping, or by any other known means. An annular seal 8b can be interposed between the second end of the side wall 10 and the bottom 8. The interior volume 7a delimited by the housing 7 is thus isolated in a sealed manner with respect to the exterior.
    The bottom 8 may include an opening 8a closed in a sealed manner by an easily deformable wall such as a flexible elastomer membrane 9 forming a bellows, which makes it possible to maintain the interior space 7a of the housing 7 at atmospheric pressure independently of the movements of the flexible membrane. 6 or temperature variations.
    The main part of the housing further comprises a transverse wall 11, perpendicular to the axis Z0, which is in contact with the partition 10. The transverse wall 11 is integral with the annular wall 10 and closes the interior space 7a of the housing at in the vicinity of the first end of said side wall 10. The transverse wall 11 can be molded in one piece with the annular wall 10.
    The transverse wall 11 may include a groove 11a open towards the partition 5 and covered by said partition 5. The groove 11a delimits the constricted passage C with the partition 5. The constricted passage C can communicate with the working chamber A by an opening provided in partition 5.
    The transverse wall 11 may also have a recess 13 (FIG. 3) open towards the partition 5 and covered by said partition 5. The groove 11a opens into the recess 13. The recess 13 may comprise an opening 13a closed by the flexible membrane 6 mentioned above. The recess 13, the membrane 6 and the partition 5 together delimit the compensation chamber B.
    The transverse wall 11 may also include a bowl 12, the concave surface 12a of which is disposed opposite a recess 5a formed in the partition 5. The recess is closed by a flexible elastomer membrane 5b which covers the bowl 12. The bowl 12 delimits with the flexible membrane 5b a pneumatic chamber P, which communicates with the interior space 7a of the housing 7, through an orifice 12b formed in the bowl 12. The orifice 12b can be centered on an axis Z2 parallel to the axis Z0.
    The housing 7 may also include a housing 14, for example of cylindrical shape, which can be formed in one piece with the side wall 10 and the transverse wall 11, and disposed under the transverse wall 11. The constricted passage C can have a first part C1 which communicates the working chamber A with the interior of the housing 14, and a second part C2 which communicates the interior of the housing 14 with the compensation chamber B.
    The housing 14 can receive by interlocking, an external casing 16 of an electric current generating device 15. As shown in FIGS. 4 to 6, the electric current generating device 15 can include a microturbine casing 17, delimiting a microturbine 19 in which a microturbine 18 is rotatably mounted around an axis of rotation Zl, for example parallel to the axis Z0. The microturbine chamber 19 can have a substantially cylindrical shape centered on the axis of rotation Zl, and it can communicate respectively with the first and second parts C1, C2 of the constricted passage, by two delimited nozzles 19a, 19b
    The two nozzles 19a, open substantially through the microturbine housing 17 19b can advantageously tangentially in the microturbine chamber 19. The nozzles 19a, 19b can open into the microturbine chamber 19 in positions substantially diametrically opposite with respect to the axis of rotation Zl.
    Advantageously, the microturbine 18 is shaped to be always driven in the same direction of rotation by the liquid of the hydraulic circuit when said liquid moves alternately in the first and second opposite directions in the constricted passage C.
    The microturbine 18 and the microturbine chamber 19 can for example be as described in the document WO2015 / 136160 mentioned above.
    As shown in FIG. 4, the electric current generator device 15 further comprises a generator 20 coupled to the microturbine 18 to produce electric current when the microturbine 18 rotates. This generator can for example be as described in the document WO2015 / 136160 mentioned above.
    As shown in FIGS. 4, 6, 10, the anti-vibration device 1 further comprises an electronic circuit 21 controlling an electromagnetic actuator 22 which is adapted to selectively block or leave free the flexible membrane 5b (or more generally, the electromagnetic actuator 22 is suitable for controlling the anti-vibration behavior of the anti-vibration device, possibly by acting on another element than the flexible membrane 5b).
    The electronic circuit 21 may for example include:
    ίο
    a converter 24 (RECT) supplied by the generator 20 (GEN) and generating a direct current from the alternating current produced by said generator 20,
    an electrical energy storage device 23 (ACC), for example a capacity 23a (or a set of several capacities) supplied by the converter 24,
    - a device control 25 (CONTR), by example including a microcontroller, powered by the device of storage 23 and controlling the actuator 22 (ACT), - a sensor 26 (SENS) connected to the device of
    control 25, for example a vibration sensor such as an accelerometer or the like.
    The entire electronic circuit 21 can be housed in the interior space 7a of the housing 7, and does not require any exchange of information with the outside or external power supply.
    Because the housing 7 is waterproof, the electronic circuit 21 does not need to be specially protected against humidity and external aggressions, which reduces the cost of the anti-vibration device.
    Optionally, the sensor 26 or an additional sensor, could be placed elsewhere than in the housing 7 (for example, it could be rigidly linked to the first frame 2), depending on the application envisaged and the mounting of the anti-vibration device 1.
    As shown in Figures 4 and 7-9, the actuator 22 may for example include a valve 36 adapted to selectively open and close the orifice 12b of the pneumatic chamber P to selectively isolate it or put it at atmospheric pressure (c 'ie at the internal pressure of the housing 7).
    This valve 36 can advantageously also act as a valve, as will be explained below, by only allowing the air outlet from the pneumatic chamber P to the interior space 7a of the housing 7 when the valve 36 closes the orifice 12a , but not vice versa.
    Advantageously, the actuator 22 comprises a permanent magnet suction cup comprising:
    a magnetic circuit 28, 34, 40 including an actuating member 34 which includes or carries the aforementioned valve 36 and which is movable between a first position (not shown) where the valve 36 is applied under the bowl 12 by closing the orifice 12b, and a second position (shown in the figures) for opening the orifice 12b where the valve 36 is spaced from the wall of the bowl 12,
    at least one spring 37 urging the actuating member 34 with a first force oriented towards the first position,
    - At least one permanent magnet 41 creating a permanent magnetic field B0 in the magnetic circuit and urging the actuating member 34 with a second force oriented towards the second position, the first force being greater than the second force when the member d actuation 34 is in the first position and the second force being greater than the first force when the actuation member 34 is in the second position,
    - at least one coil 33 supplied electrically by the control device 25.
    The control device 25 controls the passage from the second position to the first position by creating a current in a first direction in the coil 33, which creates a magnetic field B1 in the opposite direction to the permanent magnetic field B0 above, so as to reduce the magnetic field sufficient result for the spring 37 to move the actuator 34 in the first position.
    Conversely, the control device 25 controls the passage from the first position to the second position by creating a current in the coil 33, in a second direction opposite to the first direction, which creates a magnetic field B'1 in the same direction as the field. permanent magnetic B0 mentioned above, so as to increase the resulting magnetic field enough to overcome the force of the spring 37 and move the actuator 34 in the second position.
    Advantageously, the control device 25 is adapted to generate a single current pulse in the coil to selectively pass the actuating member 34 either from the first to the second position or from the second to the first position.
    This current pulse can have a duration t of less than 100 ms.
    The current pulse can also have a power p of between 0.1 W and 1.5 W.
    The electrical energy E = pt consumed by a transition between the two positions of the actuating member, is therefore very low, which contributes to the energy autonomy of the antivibration device 1, and also makes it possible to reduce the size, the weight and cost of the coil 33.
    The actuating member 34 is movable in translation along the axis Z2, for example over a stroke h of between 0.5 and 2 mm, advantageously between 0.7 and 1.5 mm, between the first and second positions. Such a displacement of small amplitude is sufficient in the present case, and also contributes to limiting the energy consumed by each transition between the two positions of the actuating member 34.
    In the particular example shown, the aforementioned magnetic circuit may include:
    a U-shaped ferromagnetic carcass 28 having a base 28b and two wings 28a extending to free ends on either side of the axis Z2,
    a pallet 35 made of ferromagnetic material which belongs to the actuating member 34 and carries the valve (the valve 36 can be an elastomer pad, for example molded onto the pallet 35), the pallet 35 being movable according to the axis Z2 and disposed between the free ends of the two wings 28a with a small air gap e left between the pallet 35 and each wing 28a,
    a core 40 of ferromagnetic material integral with the carcass 28 and extending longitudinally along the axis Z2 between a first end close to the base 28b and a second end close to the pallet 35 of the actuating member, the pallet 35 being spaced from the second end of the core 40 in the first position and in contact with the second end of the core in the second position, and the coil 33 being wound around said core.
    The permanent magnet 41 can be interposed axially between the first end of the core 40 and the base 28b of the carcass.
    The coil 33 can be wound on a support 29 of plastic or other material. The support 29 can include:
    a base 30 perpendicular to the axis Z2 and disposed on the base 28b, in contact with said base 28b,
    a core 31 extending along the axis Z2 and delimiting an axial chimney 36 in which the ferromagnetic core 40 is fitted without play, the axial chimney 36 having a first enlarged part 36a close to the actuating member 34 and a second enlarged part close to the base 30, the first enlarged part 36a forming a shoulder against which the spring bears to push the actuating member 34 towards the first position, and the second enlarged part 36b receiving an enlarged part of the core 40 so as to maintain axially
    the core 40 against the magnet permanent 41 and the magnet permanent 41 against base 28b, - a flange 31 willing under the organ
    actuation 34, the core 40 and the spring 37 projecting from the flange 32 towards the pallet 35.
    The flange 32 may include cutouts 32a in which the wings 28a of the carcass 28 are fitted.
    The flange 32 can also include guides 32b which project axially along the axis Z2 towards the bowl 12 and come to bear under said bowl 12. These guides 32b can frame the pallet 35 to guide it in its axial movement and guarantee the correct axial positioning of the electromagnetic actuator 22.
    The base 29 may include electrical contacts 39, which connect the coil 33 to the control device 25.
    The antivibration device 1 which has just been described operates as follows.
    When the vehicle in which the anti-vibration device is installed is operating, the vibratory movements of the engine produce movements of liquid in the throttled passage C between the hydraulic chambers A and B. These movements of liquid rotate the microturbine 18, so that the generator generates an electric current which is rectified by the converter 24 and stored in the storage device 23.
    When the engine is idling without the vehicle running, the relative movements between the first and second armatures 2, 3 are generally of frequency between 10 and 40 Hz depending on the type of engine and of small amplitude (less than 0.2 mm) . Under these conditions, the electric power produced by the generator 20 is relatively low, for example from a few tens to a few hundred milliwatts. Under these circumstances, detected using the sensor 26, the control device 25 controls the actuator 22 so that the actuating member 34 is in the second position, so as to leave free the flexible membrane 5b which then a decoupling effect avoiding transmitting the vibrations of the engine to the vehicle body.
    When the vehicle is moving, the so-called hash relative movements between the first and second armatures 2, 3 are of relatively low frequency (generally between 10 and 15 Hz depending on the type of motor) and of large amplitude (greater than 0.3 mm ). Under these conditions, the electric power produced by the generator 20 can be greater, for example by a few Watts (for example of the order of 2 W). Under these circumstances, detected using the sensor 26, the control device 25 controls the actuator 22 so that the actuating member 34 is in the first position. In this position, the spring being adapted to let the actuating member 34 temporarily open the orifice 12b in the event of overpressure in the pneumatic chamber P. Thus, the pneumatic chamber P gradually empties of its air towards the interior of the housing 7, under the effect of the movements of the flexible membrane 5b due to the vibratory movements of the motor, so that the movable wall is gradually pressed against the concave surface 12a of the bowl 12 as and when the vacuum is created in the pneumatic chamber P, which blocks the flexible membrane 5b.
    Two different operating modes of the anti-vibration device 1 are thus obtained according to the engine speed, detected by the sensor 26.
    As a variant, as shown diagrammatically in FIG. 11, the anti-vibration device 1 could not include an energy generating device 15, but another energy source such as a battery 42 (BATT) supplying the control device 25. This battery could for example be arranged in the interior space 7a above, which would then be adapted to be opened for the replacement of the battery. Given the low power consumption, such a replacement could take place at fairly long time intervals.
    According to another variant, not shown, the device could include a second hydraulic compensation chamber communicating with the working chamber A by a second throttled passage, and the membrane
    5b would separate the pneumatic chamber P from this second compensation chamber. In this case, the actuator 22 could control the operation of this second compensation chamber to selectively either allow movements of liquid between the working chamber A and the second compensation chamber (valve 36 open), or prohibit the movements of liquid between the working chamber A and the second compensation chamber (valve 36 closed).
