Definitions
- the invention relates to a hydraulic circuit, in particular a clutch. More particularly, it relates to a receiver device capable of receiving control information from a hydraulic circuit in the form of pressure variations, more precisely a receiver of the concentric type.
- Receivers of this kind are for example described in French patent n ° 82 03485 published under n ° FR-A-2 522 757.
- Such receivers generally comprise, on the one hand, a fixed part composed of an external body and a coaxial cylindrical guide tube and, on the other hand, a piston mounted sliding coaxially with the fixed part and defining a chamber therein. variable volume intended to be connected to the hydraulic transmitter of the hydraulic control.
- the guide tube has a transverse flange, which is assembled by crimping to the external body of the receiver.
- This arrangement involves risks of crimp breakage under the effect of the pressure prevailing in the variable-volume control chamber if the support on the casing is removed.
- the body is made from aluminum, and the crimping makes it brittle.
- the invention for its part, aims at a receiver for a hydraulic circuit of this type capable of overcoming these drawbacks.
- the receiver is simple and inexpensive to manufacture.
- the invention provides a receiver of the concentric type for hydraulic control comprising, on the one hand, a fixed part composed of an external body and a coaxial cylindrical guide tube and, on the other hand, a piston mounted to slide. coaxial with the fixed part and defining therein a variable volume chamber intended to be connected to the hydraulic transmitter of the hydraulic control, the external body comprising on its internal face a groove in which is inserted a radial edge which the guide tube has to one of its ends and which partially constitutes the bottom of the variable volume chamber.
- the use of a guide tube thus engorged makes it possible to overcome the problems of crimping and of material made brittle by the traditional method, while guaranteeing a very good seal of the variable volume chamber of the receiver, and by providing good resistance to pressure.
- Such a clogged tube eliminates the intermediate blocking piece of the radial edge of the guide tube described in document FR-A-2 754 030 so that the invention is economical.
- the guide tube comprises a cylindrical section having a flare formed by a conical section terminated by an annular edge inserted in the groove of the outer body.
- This arrangement increases the resistance of the guide tube to mechanical forces related to pressure and facilitates the insertion of the tube into the groove of the external body. This also reduces the axial size of the guide tube and facilitates the supply of the chamber.
- the external body has a tubular part and a part in the form of a collar inside which the groove is formed.
- the annular edge of the guide tube is preferably of diameter slightly greater than the diameter of the internal face of the external body.
- the receiver advantageously comprises an O-ring placed at the bottom of the groove between the outer body and the edge of the guide tube.
- a method for mounting a fixed part, using a counter tool includes steps for placing the guide tube in the axis of the external body, for maintaining the annular edge of the guide tube in contact with the shoulder. of the external body using the counter-tool, varying the angle of the conical section by the action of a punch, to bring the annular edge into the groove.
- the fixed part comprises a power inlet connected to the collar of the external body.
- the feed inlet opens through an opening arranged on the internal face of the external body formed substantially opposite the conical section of the guide tube. This gives easier flow of the hydraulic fluid in the variable volume chamber of the receiver, when it is pressurized. It will be appreciated that this type of use with a clogged guide tube is applicable to a large number of receivers, in particular to those described in the documents FR-
- the seal associated with the piston can be in the form of an O-cup coming as close as possible to the frustoconical section when the clutch is engaged.
- the head of the piston comprises, in an exemplary embodiment, at least two segments in the form of a ring arc assembled, by means of positioning, in a ring carrying said seal.
- This arrangement makes it possible to produce by molding a piston head of complex section, then to assemble it by suitable means, without being limited by the release constraints.
- the joint is a joint for joining the segments. Thanks to the invention there is therefore obtained a hydraulic receiver which is simple to manufacture and of low cost price, which for this purpose requires in particular less machining than in the traditional technique, and is preferably made of light material.
- the ring arc segments In order to allow the piston head to be assembled with the other parts constituting the concentric receiver, the ring arc segments have a staircase rim on their rear face.
- the piston thanks to these provisions comprises in one embodiment a protective skirt terminated by an external scraper seal of suitable shape to come to slide on the tubular part of the outer body of the receiver.
- This arrangement overcomes the conventional protective bellows and therefore simplifies the mounting of the concentric receiver, while ensuring good protection of the piston against the entry of dust.
- This provision is applicable to any type of receiver of the concentric type, but goes well with the use of a congested guide tube because a good concentricity is obtained between the guide tube and the external body which limits the risks of jamming at level of the protective skirt scraper seal.
- the receiver can therefore comprise a piston-carrying tube of cylindrical shape terminated by an annular flange on the side of the variable-volume chamber, said piston-carrying tube being of metallic nature and being mounted around the guide tube, a means for securing the piston around this piston holder being provided.
- the functions, on the one hand, of resistance to deformations due to temperature and mechanical forces due to the securing means are separated, and, on the other hand, of transmission of the thrust from the piston to the declutching member, namely the declutching stop.
- the metal piston carrying tube takes up the thermal and mechanical forces of the fastening means, while the piston is dimensioned to transmit only the pressure forces.
- the means for securing the piston around the piston carrying tube is preferably an elastic self-centering washer bearing on the piston carrying tube, such as that which is associated with a so-called declutching stop.
- the self-centering washer is advantageously made in the form of a frustoconical ring and has deformable spouts.
- the piston carrying tube then has a shallow groove formed on its front end, and intended to receive the deformable spouts of the self-centering washer.
- the shallow groove of the piston-carrying tube has a front side inclined at a slope of approximately 45 °.
- the deformable spouts of the self-centering washer form a dihedral with the frustoconical ring of said self-centering washer.
- the piston is preferably made of plastic.
- the piston has structural reinforcement ribs, oriented in a direction substantially parallel to the axis of the piston. This arrangement makes it possible to choose a geometry of the piston with good structural strength, while providing recesses reducing the material used and the overall weight.
- the receiver comprises a scraper seal placed around the guide tube under the piston carrying tube.
- This scraper seal is extended by a set of tabs, forming guide pads, carried by the guide tube and arranged under the piston-carrying tube.
- the piston carrier tube is thermally isolated in combination with the piston.
- the guide shoes are, in an advantageous arrangement, six in number, each covering an angle of approximately 50 °, separated by sectors of 10 ° angle along the guide tube.
- the guide pads are preferably terminated at their end remote from the scraper seal by radial flanges. This will facilitate the assembly of the guide shoes with the piston head.
- the guide pads and the scraper seal are advantageously made of plastic. All these provisions are applicable to other types of receivers but go well with the use of a clogged guide type due to the good concentricity of the guide type and small deformations of the guide tube under the effect of pressure variations. . Other characteristics of the invention will appear on reading the description and the claims which follow.
- - Figure 2 is a half sectional view of the receiver alone, on a larger scale
- - Figures 3 and 4 are partial detail views of the guide tube before assembly with the outer body alone on a larger scale
- FIG. 5 is a partial sectional view showing the elements forming the piston head and the seal;
- - Figure 6 is a view similar to Figure 5, the cutting plane being different;
- FIG. 7 is a half sectional view along VII-VII of Figure 5;
- FIG. 8 is a view along VIII-VIII of Figure 2;
- FIG. 9 is a partial sectional view showing the establishment of the piston stop washer
- FIG. 10 is a partial sectional view of the piston stopper
- FIG. 11 is a partial sectional view showing the piston stop stop in the operational position.
- FIG. 1 shows a sectional view of a clutch.
- the main elements of the conventional clutch 1 here of the pushed type, with in particular the cover 7, the reaction plate 2, the pressure plate 3 on which the diaphragm 4 comes to bear, here in the position clutch disengaged, these two plates 2 and 3 being intended to tighten the friction linings 5 of a friction disc 6 equipped with a hub with internal grooves.
- Such clutches are well known per se and such, for example as that described in detail in the document FR-A-2 730532.
- the receiver 8 forming part of the clutch control, for disengaging the clutch, is here of the concentric type, and is visible in FIG. 1 in the position for which the clutch is disengaged, or disengaged, and on the Figure 2 in the rest position for which the clutch is engaged.
- the receiver 8 comprises two annular parts in relation to the cylinder-piston, namely a fixed part 9 by which the receiver 8 is mounted on a fixed structure such as the casing 10 of the gearbox, and a mobile part consisting of a piston 11 of generally annular shape sliding axially partially inside a cavity 12 also annular defined in the fixed part 9 of hollow form.
- This cavity 12 is blind and suitable for being pressurized and depressurized.
- the control fluid here is oil. It is thus defined by the piston 11, in the cavity 12, a variable volume chamber 13.
- the fixed part 9 has a supply inlet 14 connected to the cavity 12.
- This supply inlet 14 is extended by an internal channel 15 opening through an opening 16 in the bottom of the cavity 12 where the variable volume chamber 13 is defined.
- the power input 14 is connected by a conduit 17 to the transmitter (not shown) of the clutch control.
- This transmitter is actuated in a known manner by an actuator of any type (not shown), such as a clutch pedal or an actuator with a motor, for example electric, connected to a computer to act, according to predetermined programs, on the piston of the transmitter.
- variable-volume chamber 13 When the control fluid of the variable-volume chamber 13 is pressurized from the transmitter, the piston 11 is allowed to move to the left in FIG. 2, so that the volume of the variable-volume chamber 13 increases. In the position visible in FIG. 1, the piston 11 is extended as far as possible from the cavity 12, the variable-volume chamber 13 then having a maximum volume.
- the piston 11 actuates in its stroke a clutch release bearing 18 which pushes the internal end of the fingers of the diaphragm 4 to allow the clutch to be disengaged, as shown in FIG. 1.
- variable-volume chamber 13 By depressurizing the variable-volume chamber 13, its volume decreases, the fluid returning through the conduit 17 to the transmitter; the piston 11 then moves to the right of FIG. 1, under the return effect of the diaphragm 4 which returns to its rest position in which, bearing on the cover 7 axially integral with the reaction plate 2, it elastically urges the pressure plate 3 towards the reaction plate 2 for clamping, between the two plates, linings 5. The piston finally reaches its rest position as shown in FIG. 2.
- the declutching stopper 18 forms the element of attack acting by pushing on the fingers of the diaphragm 4, and consists, here, of a ball bearing whose rotating external ring 19 is in permanent contact with the fingers of the diaphragm 4 thanks by the action of a preload spring 20 acting between the fixed part 9 and the piston 11 which cooperates with the non-rotating internal ring 27 of the stop 28, under the conditions described below.
- the fixed part 9 of the receiver 8 is secured in a known manner to the gearbox casing 10, for example by means of ears not visible in the drawings.
- the fixed part 9 is composed of two main coaxial elements which are on the one hand an external body 21 made of a moldable material such as aluminum, and a tube concentric guide 22.
- the outer body 21 has a front tubular part 23 and a thicker rear part in the form of a flange 24; the fluid opening 16, connected by the internal channel 15 to the supply conduit 17, opens into the internal face of the flange 24.
- the guide tube 22 is preferably made of metallic material and forms a support and guide member for the piston 11. As can be seen in FIG. 2, the guide tube 22, mainly composed of a cylindrical section 39, is longer in its axial direction as the outer body 21. It is thin, which reduces the radial size of the receiver 8. This tube 22 is crossed by the input shaft of the gearbox not shown.
- the guide tube 22 has, at the end of its cylindrical section 39, a flare formed by a conical section 30 terminated by a transverse annular edge 31.
- This annular edge 31 is secured to the outer body 21, to close the cavity 12 and form the bottom thereof; to do this, the external body 21 has on its internal face 35 a groove 32, FIG. 3, and is stage internally in diameter, so as to create a shoulder 33 internally extending one of the sides of the groove 32, here the front side.
- An O-ring 34 of known type is placed in the bottom of the groove 32 so as to seal the connection, therefore that of the variable-volume chamber 13.
- the guide tube 22 has such a shape before mounting that its annular edge 31 is in line with the internal face 35 of the external body 21.
- the annular edge 31 is then brought into contact with the shoulder 33 of the external body 21, FIG. 4, and is held in this position by a counter-tool 70.
- the conicity of the conical section 30 is then varied by the action of a tool
- the opening 16 for supplying the variable volume chamber 13 is disposed axially substantially in line with the conical section 30 of the guide tube 22 which defines the minimum volume of said chamber; this arrangement limits the axial size of the receiver 8 and allows good flow of the control fluid in the chamber 13 thanks in particular to the section 30.
- the front face of the flange 25 (on the left in FIG. 2) of the external body 21 serves as a support for the preload spring 20, the other end of which is supported on a transverse flange 26 which has the piston 11 at its end before.
- a scraper seal 45 which contributes to preventing the penetration of dust within the variable-volume chamber 13, surrounds the guide tube 22. It carries a set of legs extending axially and forming guide shoes 28; the scraper seal 45 and its guide shoes 28 are axially integral with the piston 11 and caused to slide on the outside surface of the guide tube 22 and allow the piston 11 to be guided.
- the guide shoes 28, which are six in number here, each cover an angle of approximately 50 ° and are separated by sectors of 10 ° angle along the guide tube 22 (see Figure 7); the scraper seal 45 and the guide shoes 28 are in one piece and made of plastic material having good sliding properties. The number of pads 28 depends on the applications.
- the guide shoes 28 are terminated at their end remote from the scraper seal
- a steel piston support tube 46 ( FIG. 2, of substantially cylindrical shape, terminated at its rear part by an annular flange 47 which is arranged, in the assembled configuration of the receiver 8 such that can be seen in FIG. 2, between the rear face of the piston 11 and the support washer 57.
- the piston carrying tube 46 is produced in the example described here, without limitation, in steel, which allows it to withstand mechanical forces without excessive deformation.
- the piston tube 46 is adapted to take up the forces transmitted by a self-centering washer 49, described below.
- the piston 11 is made of plastic, which reduces costs, avoiding for example the need for machining of a metal piston, the piston 11 can here be molded.
- the piston 11 and the scraper seal 49 with these pads 28 thermally insulate the piston support tube 46, which deforms very little. The risks of jamming of the piston 11 are reduced by the presence of the tube 46 and of the pads 28.
- the main function of the piston 11 is then to transmit the mechanical forces created in the variable volume chamber 13, along the axis AA, to the stop 18.
- the piston 11 comprises ribs 58 of structural reinforcement, oriented axially in a direction substantially parallel to the axis AA, extending towards the rear of the piston 11 from its front face 54, and of dimension adapted to allow the passage of the piston 11 and the ribs 58 in the cylindrical space formed between the piston-carrying tube 46 and the tubular part 23 of the external body 21.
- the front face 54 of the piston 11, of substantially annular shape, is therefore intended to receive the clutch release bearing 18 in support.
- the piston 11 includes a protective skirt 59, which has the shape of an annular cylindrical wall of small thickness of axis AA, the end of which free is shaped as an outer scraper seal 60.
- the protective skirt 59 takes place during mounting around the tubular part 23 of the outer body 21 and inside the preload spring 20, the outer scraper seal 60 being suitable for rubbing against the external body 21.
- the preload spring 20 is supported on the transverse flange 26 carried by the piston 11 and which extends radially at the birth of the protective skirt 59.
- Such a protective skirt 59 advantageously replaces the bellows usually used in conventional type concentric receivers.
- the piston 11 therefore has a "U" shaped section surrounding the piston carrying tube 46, and of which a first branch of greater resistance structural, forming the actual piston, is disposed between the piston support tube 46 and the tubular part 23 of the external body 21, and a second thin external branch forming the protective skirt 59 whose end 60 scrapes the external face of the tubular part 23 of the external body 21 to protect the internal part of the receiver 8 against impurities.
- the receiver 8 has, in a known manner, an axial clearance 62 and a radial clearance, FIG. 5, between the piston head 63, described below, and the piston 11 proper, to take into account possible variations in position, of the fingers of the diaphragm 4 for example.
- the piston head 63 is composed, FIGS. 5 and 6, of the support washer 57 of steel, already mentioned, placed in the rear part (at right in the figures) of the annular flange 47 which comprises the piston-carrying tube 46, as well as of several segments 64, 65, 66, here three in number, of annular shape each carrying a sculpture also annular in the shape of a lug 67 oriented axially towards the variable volume chamber 13.
- These segments 64, 65, 66 have on their rear face a staircase edge 61 carried by an axial tab 71.
- the shape of the piston head 63 in several annular segments 64, 65, 66 is justified by the fact that a molding in an annular piece comprising both the lug-shaped sculpture 67 and the staircase rim 61 is not easily achievable.
- a cup seal 68 of generally O-shaped shape is placed on the lug-shaped sculptures 67 of the three segments 64, 65, 66, and ensures the sealing of the variable volume chamber 13.
- the seal 68 constitutes an assembly part for the segments 64, 65, 66.
- the steel support washer 57 comprises positioning pins 69 in number equal to that of the segments, here three, and intended to facilitate the respective positioning of said segments. These positioning pins 69 cooperate with bores 72, Figure 6, formed in the segments 64, 65, 66 to ensure their precise positioning. Once angularly positioned, these two by two have a circumferential clearance of the order of about 0.1 mm.
- the piston-carrying tube 46 is of axial length slightly greater than that of the piston 11, so as to protrude a little at the front thereof, to allow the mounting of a so-called self-centering washer 49.
- the piston carrying tube 46 has, at its front end, FIG. 2, a shallow groove 48, better visible in FIG. 9, the function of which is to serve as a support for the self-centering washer 49.
- This shallow groove 48 comprises preferably a non-vertical front flank 52, for example inclined at 45 °.
- the self-centering washer 49 of the "Belleville” type, is of slightly frustoconical shape before mounting, as shown in solid lines in FIG. 9. Its thickness is for example from 0.5 to 0.6 mm.
- the self-centering washer 49 When mounting the clutch release bearing 18 on the receiver 8, the self-centering washer 49 is placed in the axis of the piston holder tube 46, then is pushed using a punch 51, as it is seen in FIG. 9, in the groove 48, in which, by deformation, the ends of the spouts 50 take place.
- the Belleville washer is chosen so as to have a deflection curve as a function of the applied force having a flat range, corresponding to a significant deformation possible while maintaining a constant specific force applied to the washer. It is this characteristic which is used to deform the spouts 50 in this range during assembly.
- the self-centering washer 49 then produces a force on the non-rotating ring 27 of the stopper declutching, thus causing the desired axial locking of the stop 18 which retains freedom of radial movements for its centering, as known per se. It is understood that the assembly of the piston 11 and the piston support tube 46 is completed by the self-centering washer 49 which serves not only to axially block the stop 18 against the piston, but also to block the piston 11 against the annular flange 47 of the piston holder tube 46. This washer 49 remains generally in transverse orientation after assembly, only the spouts 50 are deformed. Here we have amplified the deformation of the washer 49.
- the guide tube 22 carries at its front part, on the left in the figures, a stopper 29 intended to axially limit the stroke of the piston 11.
- the stopper 29 consists, FIG. 10, of a "Belleville" type washer comprising a frustoconical ring 40 the internal part of which is extended along lugs 41 directed on the convex side with respect to the ring 40 at an angle with it, here 90 degrees; the tabs 41 each terminate in a terminal rim forming a hook 42 directed towards the side of the ring 40.
- the guide tube 22 has at the front end of its cylindrical section 39 a groove 43 formed on its internal face 44 and adapted to receive the edges 42 of the tabs 41 of the stopper 29.
- the frustoconical ring 40 When mounting the stopper 29, the frustoconical ring 40 is tilted using a tool to its planar configuration and the tabs 41 are introduced into the guide tube 22 until the flanges 42 of the tabs 41 take their place in the groove 43 of the guide tube 22.
- the frustoconical ring 40 takes the form of a substantially planar ring perpendicular to the axis of the guide tube 22.
- the outer periphery of the guide tube 22 is smooth at its front end. Thanks to the stopper 29, the axial length of the tube 22 can be reduced or the guide length thereof can be increased.
- the operation of the receiver 8 according to the invention is identical to that of a conventional concentric receiver and will not be detailed here.
- the guide tube 22 has an initial diameter, before mounting, slightly greater than that of the internal face 35 of the outer body
