    [0001] The invention relates to a transmitter for a synchronization assembly of a gearbox, comprising a transmitting disk and at least one disk of a gearbox. clutch arranged on a side face of the transmitting disc. The invention also relates to a method of manufacturing a transmitter for a timing assembly of a gearbox. A gearbox synchronization assembly as used in particular in motor vehicles in general terms serves to establish a rotationally rigid connection between a transmission shaft and a gear wheel or a gear wheel arranged on the wheel. 'drive shaft as crazy gear. In a first step of the gear change operation, the synchronization assembly ensures that the speed of the gear gear to be switched is adapted to the speed of the transmission shaft. In a second step, a rotationally solid connection is then established between the transmission shaft and the gear wheel. The corresponding speed is then engaged. A common type of synchronization set is known as "BorgWarner synchronization". This synchronization assembly uses a sliding sleeve which is arranged to rotate but axially displaceable on a synchronizing body which is integrally connected in rotation to the transmission shaft. The sliding sleeve can be moved axially from an initial position to a gear wheel. A synchronization ring is thus first activated, which synchronizes the speed of the gear with the speed of the drive shaft. As soon as this operation is completed, the sliding sleeve can be moved in the axial direction until it establishes an integral connection in rotation with the corresponding speed gear. As an alternative for this type of synchronization set, a type using the transmitter mentioned in the introduction is known. An example for this is in DE 10 2010 036 278 A1. In general terms, the transmitter groups the synchronizing body and the sliding sleeve in a component which is rotatably mounted relative to the transmission shaft and which can be moved in the axial direction. When the transmitter is moved from a neutral position in the axial direction, a synchronization ring (or also a set consisting of several synchronization rings) is first activated, whereby the speed of the corresponding gear gear is synchronized with the speed of the drive shaft. In a second step, it is possible to switch the transmitter, whereby a link secured in rotation between the transmission shaft and the corresponding gear pinion is established. The object of the invention is to provide a transmitter capable of being manufactured at low cost. To achieve this object, according to the invention, it is provided in a transmitter of the type mentioned in the introduction that the clutch disc and the transmitting disk are connected to one another in a secured manner by local welding points. These can be made quickly, reliably and inexpensively, for example by resistance welding. Since the transmission of torque of the transmission gear wheels to the transmission shaft is achieved substantially directly via the clutch disks and not via the transmitting disk, the welding points are not subject to particularly high stresses. Bosses are preferably provided which form the welding points. This ensures that the weld points are precisely made to the desired positions.
    [0002] According to a preferred embodiment, spacers are provided on which the bosses are made, in particular on the transmitting disc. The spacers allow the arrangement of a pressure piece in the transmitting disk, whose dimensions in the axial direction are greater than the thickness of the transmitting disk. This allows in particular the arrangement of a comparatively strong compression spring in the transmitting disk. To achieve the above mentioned purpose, a method of manufacturing a transmitter for a synchronization assembly of a gearbox is also provided according to the invention, which comprises the following steps: a disk of clutch and a transmitter disk are first provided. The clutch disc and the transmitting disk are then fixed to one another by projection welding. The assembly thus produced is then hardened. This series of welding and hardening ensures that the material present during welding the optimal properties for this purpose. The assembly can be cured freely, that is to say it is hardened and suddenly cooled. It is also possible to harden the assembly on a mandrel which engages for example in an internal toothing of the clutch plate and thus limits the hardening distortion. According to a preferred embodiment, it is provided that the transmitting disk is provided with at least one recess and that a pressure piece is mounted in the recess after curing the assembly. The pressure piece can be inserted mechanically very simply in its associated recess, the pressure piece, if any, then being guided between the clutch disks. According to a preferred embodiment of the invention, it is provided that the pressure piece is snapped into the recess. This ensures the maintenance of the pressure piece in its associated recess without additional auxiliary means 20 after its assembly. According to a preferred embodiment of the invention, it is provided that the pressure piece is provided with a base part and a guide part, the base part being placed between two clutch disks arranged on transmitting disk faces which are diverted from each other, and that the guide portion is guided in the axial direction between opposite edges of the recess in the peripheral direction. In this embodiment, a particularly precise guidance of the pressure piece in the recess is obtained, which optimizes the gear change behavior. Advantageous embodiments of the invention emerge from the dependent claims. The invention is described below by means of an embodiment shown in the accompanying drawings.

XXI of Figure 18, and - Figure 22 a section along the plane XXII-XXII of Figure 3. Figure 1 shows schematically a synchronization assembly which has two wheels transmission teeth 1, 2 which are capable of being connected rotatably to the transmission shaft 3 according to the speed engaged. For this purpose, a transmitter 10 is provided, which can be displaced axially with respect to the transmission shaft 3. When the terms "axial" or "radial" are used in the following, these relate to the axis of rotation of the transmission shaft 3 and the transmitter 10. The basic structure of the synchronization assembly is explained in the following with reference to FIGS. 1 to 5, while the details will be explained more The transmitter 10 has a transmitting disk 12 which is provided with a clutch disk 14 on each of its lateral faces. Each clutch disc 14 has on its radially inner periphery a toothing 16 of the transmission shaft and on its radially outer periphery a clutch gear 18 (see in particular FIG. 2). The gearbox teeth 16 of the clutch disks 14 are integrally received in rotation but axially displaceable on an external toothing 20 of a transmitter sleeve 22. The transmitter sleeve 22 is in turn rotatably mounted on the transmission shaft 3. To this end, the transmitter sleeve 22 can be provided with an internal toothing 24 (see in particular FIGS. 3 to 5). The clutch gear 18 of each clutch disc 14 is intended to cooperate with gear gear clutch gear teeth 26 associated therewith, which gear is provided on the gear wheels 1, 2. - The exemplary embodiment shown, each gear pinion clutch gearing 26 is provided on the inner face of a friction ring 28, the outer side is provided with a friction surface 30 inclined slightly conical. Each friction ring 28 is integrally connected in rotation, for example welded or brazed to its associated gear tooth 1, 2. Two synchronizing rings 32 are arranged on the transmitting disk 12, which are located on either side of the transmitting disk 12 and are intended to cooperate with the friction surfaces 30 of the friction rings 28. For this purpose, the rings of FIG. synchronization 32 are provided on their inner face with a friction lining 34. The synchronizing rings 32 are in principle connected to the transmitting disk 12 integrally in rotation but are nevertheless able to rotate over a small angular zone with respect to this. this. The synchronizing rings 32 are further mounted on the transmitter disk 12 in the axial direction, but may be moved along a certain path in the axial direction from a median or initial position. Each synchronizing ring 32 is provided with three different types of tabs which extend through or at least into orifices, recesses or associated depressions of the transmitting disc: connecting tabs 36, 37, stop tabs 38 and locking tabs 40. The connecting tabs 36, 37 serve to connect the two synchronizing rings 32 mechanically in the axial direction. For this purpose, each synchronizing ring 32 has a connecting lug 36 which has a wide head at its free end, which passes in the synchronizing ring side section of the connecting lug 36 by a narrower groove. Each connecting lug 37 has a recess which comprises a larger section adapted to the dimensions of the head of the connecting lug 36, as well as a narrower section adapted to the dimensions of the groove of the connecting lug 36. When they are engaged with each other, the connecting tabs 36, 37 extend through two orifices 42 associated in the transmitter disk. The width of the orifices 42 in the peripheral direction is greater than the width of the connecting tabs 36, 37 in the peripheral direction. The stop tabs 38 have a constant width and extend into recesses 44 which are also provided in the transmitting disc 12. The width of the recesses 44 in the peripheral direction is slightly greater than the width of the stop tabs 38 in the peripheral sense. The locking tabs 40 each extend into a recess 46 in the transmitting disc 12. The ends facing each other of the locking tabs 40 are in the initial position opposite to each other and to each other. center inside the recess 46 (see in particular Figure 4). Each locking lug 40 has, near its free end, two locking surfaces 48 which are diverted from one another and which extend obliquely with respect to the extension direction of the locking tabs 40.
    [0003] Here, the locking surfaces 48 enclose together with an extension of the outer edges of the locking tabs 40 an angle of an order of magnitude of 60 °. The blocking surfaces 48 cooperate with the edges 50 of the corresponding recess 46 which are opposed and which extend parallel to each other, concretely with a respective chamfer 52 provided on the corresponding edge. The orientation of the chamfers 52 corresponds to the orientation of the blocking surfaces 48 so that they can rest against each other in a planar manner. The locking tabs 40 each have on the radially inner side of their free ends a centering chamfer 54 (see in particular FIG. 4) on which a pressure surface 56 facing outwardly of a pressure piece 58 engages. Each pressure member 58 has a guide portion 60 which is axially maintained between the edges 50 of the corresponding recess 46, a base portion 62 which is arranged at the radially inner end of the recess 46, and a compression spring 64 which urges the guide portion 60 and the base portion 62 with a force which attempts to move the guide portion 60 away from the base portion 62. As is particularly visible in the figure 2, the transmitter has for each synchronization ring 32 four locking tabs 40 which are regularly spaced from each other in the peripheral direction, and two connecting tabs 36, 37 diametrically op placed one to the other and two stop tabs 38 diametrically opposite one another. The diameter defined by the two connecting tabs 36, 37 is then perpendicular to the diameter defined by the two stop tabs 38. In other words: the connecting tabs and the stop tabs are arranged alternately at an angle 90 ° to each other. The operation of shifting and synchronizing the speeds of the transmission shaft and the transmission gear to be switched is carried out in broad outline in the same manner as that described in DE 10 2010 036 278 A1. When a speed is to be passed, the transmitting disk 12 is moved in the axial direction by means of an actuating device (not shown here). The two synchronizing rings 32 connected to each other are driven in the axial direction, since the pressing surfaces 56 of the pressing pieces 58 mounted on the transmitting disk 12 are between the two inclined centering chamfers 54. in V and that the spring force provided by the compression springs 64 generates sufficient friction. As soon as the synchronizing ring 32 comes into engagement with the friction surface 30 associated with the transmission gear to be switched, the synchronizing ring (assuming a difference in speed between the transmission gear and the transmission shaft ) is driven in the peripheral direction until one of the respective outer edges of each of the two stop tabs 38 bears against the edge of the corresponding recess 44. The position of the synchronization rings in the peripheral direction is thus defined. When in this state the transmitting disk 12 is further moved in the axial direction, it moves axially relative to the synchronizing rings 32 since the synchronizing ring 32 is axially supported on the friction surface 30 of the transmission gear wheel to switch. Due to this axial displacement of the transmitting disk 12 relative to the synchronization ring 32, one of the chamfers 52 on the edge of each recess 46 comes to bear against one of the locking surfaces 48 on each of the locking tabs 40, more precisely those that have been displaced towards each other due to the relative movement between the synchronizing rings 32 and the transmitting disk 12. The transmitting disk 12 can be moved farther in the axial direction only when the rings 32 may be turned upside down in the circumferential direction via the locking surfaces 48 of the synchronizing rings and the chamfers 52 of the transmitting disc cooperating with one another until the blocking 48 no longer rest on the chamfers 52 but the outer edges of the axially extending locking tabs 40 slide along the edges 50 of the recesses 46. The upside-down rotation of the synchronizing ring 32 in the circumferential direction is however (expressed in a simplified manner) only possible when the speeds of the transmission gear wheel to be switched and of the transmission shaft are adapted. one to another. Concretely: the release of the synchronizing ring 32 is possible when the release torque 20 (counter torque) resulting from the switching force and the blocking geometry (chamfer angle and coefficient of friction) is greater than the synchronization torque on the friction surface of the synchronization ring. When the speeds of the transmission gear and the transmission shaft are matched to each other, the synchronizing rings 32 are turned slightly in the peripheral direction (due to the effect of the bevels 52 on the blocking surfaces 48) so that the transmitter disk 12 can be further switched in the axial direction. For this purpose, the guide portions 60 of the pressing pieces 58 deflect radially inwards as they are moved inwardly by the centering chamfers 54. The transmitting disc 12 is moved axially the clutch disc 14 of the clutch disc 14 arranged in the direction of travel engages in the corresponding speed gear clutch gearing 26 in the direction of travel. A link secured in rotation is thus established from the transmission shaft 3, via the transmitter sleeve 22, the transmission shaft toothing 16, the clutch disk 14, the clutch teeth 18 and gearwheel clutch toothing 26 to the corresponding transmission gearwheel.
    [0004] The structure of the pressing pieces 58 and their mounting in the recesses 46 of the transmitting disk 12 are explained below by means of FIGS. 6 to 17. The guide portion 60 of each pressure piece 58 is made of plastic and is made of in particular as an injection molded part. It has a cross-member 70 (see in particular FIGS. 9, 10 and 12), two interlocking arms 72 extending parallel to each other in the same direction from its diverted ends. the other. On the side opposite to the engagement arms 72, the cross member 70 is provided with the pressure surface 56. This is made slightly curved, the radius of curvature determining the curvature in the peripheral direction being arranged on a median plane M on the side to which the two engagement arms 72 also extend (see Figure 12 the radius sketched). The radius r corresponds approximately to the radius on which the locking tabs 40 are located. The outer edges of the engagement arms 72 diverted from each other are each provided with a guide contour 74 formed by the guide surfaces 76 arranged in V (see Figure 7a). The vertices of the two V-shaped guide contours 74 are rounded, and the two vertices are rotated toward each other. In other words: the guiding contours 74 are in the form of grooves along the outer edges of the latching arms 72. Instead of the V-shape in the region of the contact between the latching arms 72 and the transmitter disk, it is also possible to use other configurations. Examples are shown in Figures 7b through 7e.
    [0005] In Figure 7b, the edge of the transmitting disk 12 is concave on its side facing the latching arm 72 corresponding, more precisely (seen in cross section) with a rectangular groove. An outer edge formed convexly complementary manner of the latching arm 72 corresponding engages therein. In Figure 7c, the edge of the transmitting disk 12 is also concave on the side facing the latching arm 72 corresponding, more precisely (seen in cross section) in the form of a cavity with an arcuate bottom. An outer edge formed convexly complementary manner of the latching arm 72 corresponding engages in the cavity. In Figure 7d, the edge of the transmitting disk 12 is convex on its side facing the latching arm 72 corresponding, more precisely (seen in cross section) with a rectangular projection. This is received in a groove made complementary with a rectangular cross section in the outer edge of the latching arm 72 corresponding. In Figure 7e, the edge of the transmitting disk 12 is also convex on its side facing the latching arm 72 corresponding, more precisely (seen in cross section) as a projection with an arcuate front face. This is received in a convex cavity formed complementary to the outer edge of the latching arm 72 corresponding. Two V-shaped sliding guide surfaces 78 are formed on each of the inner edges of the latching arms 72 facing each other (see particularly Fig. 11). Here too the vertex of the V-shaped contour is made rounded, and the vertices are opposite. The two V-shaped contours on the inner side and the outer side of the engagement arms 72 are thus oriented in the same direction. The angles are however different.
    [0006] While the guide surfaces 76 together enclose an angle of less than 90 °, the sliding guide surfaces 78 together enclose an angle that is greater than 90 ° (also measured from the "inside" of the V-shaped contour). The angle opposite the vertex for the guide contour 74 is an order of magnitude of 60 °, while the opposite vertex angle for the sliding guide contour formed by the sliding guide surfaces 78 is an order of magnitude of 120 °. At the free end, the two latching arms 72 are each provided on the inside with a latching conformation 80, which is in the form of a bead or protrusion (see in particular FIG. 12). The base portion 62 (see particularly Figs. 9 and 14-17) has a plate-like bottom portion 82 from which two upright-shaped projections 84 extend which together form a spring bearing for the compression spring 64. A circular cavity 86 is here provided between the two projections 84, which serves to receive one end of the compression spring 64. The cavity is not necessarily required.
    [0007] On their inner faces turned towards each other, the two projections 84 are made curved, the radius of curvature being adapted to the outer diameter of the compression spring 64. The outer faces diverted from one another projections 84 are provided with sliding guide surfaces 88 which are inclined in the same manner as the sliding guide surfaces 78 on the guide portion 60. The sliding guide surfaces 78 of the guide portion 60 together with the guide surfaces 60 sliding guide 88 of the base portion 62 a sliding guide along which the guide portion 60 is slidably provided with respect to the base portion 62 and is received thereon.
    [0008] An engagement conformation 90 which is also beaded or protruded is provided on each of the sliding guide surfaces 88 of the projections 84 of the base portion 62. The engagement conformation 90, as seen from FIG. bottom portion 82, is arranged at a level of an order of magnitude of one third of the height of the projections 84.
    [0009] The smaller end faces diverted from each other to the bottom portion 82 of the base portion 62 are each formed as snap ends. For this purpose, small projections in the form of beads are provided on the end faces. Each pressure piece 58 forms a pre-assembled unit (see FIG. 9).
    [0010] This unit is composed of the base portion 62, the guide portion 60 and the compression spring 64. For the mounting of a pressure piece, the compression spring 64 is inserted between the two projections 84. The guide portion 60 is placed on the base portion 62 so that the engagement conformations 80 of the engagement arms 72 engage behind the engagement conformations 90 of the projections 84 (see the state in FIG. 9). In this state, the compression spring 64 is slightly prestressed. However, it is not able to separate the guide portion 60 from the base portion 62 since its spring force is less than the engagement-forming coupling force of the engagement formations 80 and 90.
    [0011] The pressure pieces 58 are inserted into the recesses 46 of the transmitting disc 12 so that the guide faces 76 cooperate with the chamfers 52 on the edges 50 of the recesses 46 (see in particular Figure 7). The guide portions 60 are thus received in the recesses 46 so as to be movable in the radial direction but reliably retained in the axial direction therein. The insertion of the pressing pieces 58 into the recesses 46 is facilitated by insertion contours 53 which are connected to the edges 50 of the radially inner side (see in particular FIG. 6). When mounting the pressure pieces 58 in the recesses 46 of the transmitting disc 12, the snap ends 92 of the base portions 62 engage a retaining section 47 suitably formed at the radially inner end of each recess. 46 (see Figure 6). The pressure pieces 58 are thus pre-mounted in the transmitter disk 12 (see also FIG. 8).
    [0012] When the synchronizing rings 32 are mounted on the transmitting disc 12, the pressing surfaces 56 of the pressing pieces 58 bear against the two centering chamfers 54 facing each other of the locking tabs 40 (see FIG. figured 4 and 6). Since pressure surfaces 56 are circumferentially curved, linear contact is produced. When the transmitter disk 12 is mounted on the transmitter socket 22, the base portion 62 bears against the outer toothing 20 of the transmitter socket 22 (see FIG. 6) so that the base portion 62 is supported in the radial direction. The base portion 62 therefore can not be pushed inwardly out of the retaining section 47, even when the guide portion 60 is displaced radially inward (in a switched position of the transmitting disk 12), therefore when the compression spring 64 is more strongly prestressed compared to the initial state. The manner in which the clutch discs 14 are attached to the lateral faces of the transmitting disc 12 is described in the following with reference to FIGS. 18 to 22. The two clutch discs 14 are welded to the transmitting disc 12, 10 more precisely by welding by bosses (thus by resistance welding at specific points). Each clutch disc 14 is attached to the transmitting disc 12 at four welding points 100 regularly spaced from each other in the peripheral direction. These points are defined by material projections 102 alternately produced in opposite directions by plastic deformation of the material of the transmitting disc 12, more precisely in a direction perpendicular to the plane defined by the transmitting disc (perpendicular to the drawing plane of the Figure 18 and in the direction of the arrow P of Figure 19). On the side opposite to the material projection 102, a cavity 104 is thus produced.
    [0013] The material projections 102 later forming the welding points 100 are made on spacers 106 which are also made by plastic deformation of the material of the transmitting disk 12. The spacers 106 are produced by providing an imprint 108 (see in particular FIG. 19) on the opposite side on the transmitter disk 12.
    [0014] As can be seen in FIG. 18, the spacers 106 and the indentations 108 are respectively arranged in pairs in the same order between adjacent recesses 46 for the pressing pieces 58. Thanks to the spacer 106, it is respectively provided between the transmitting disk 12 and the clutch disks 14 a distance a (see for example Figure 22). The distance a allows the use of a compression spring 64 with a diameter greater than the thickness of the transmitting disk 12. It is thus possible to use a spring having a higher spring constant. Fig. 19 shows the spacers 106 in a state in which the transmitting disk 12 is in the form of a blank. In this state, the material projections 102 are present. To connect the transmitting disk 12 to the two clutch disks 14, they are arranged and oriented on the two lateral faces of the transmitting disk 12. They are then fixed to each other by projection or resistance welding, the projections of material 102 based on the spacers 106 so that the clutch disks 14 rest flatly on the spacers 106. This is visible on the one hand in Figure 22 and is further symbolized in Figure 20 on which the Spreaders 106 are shown without material projections 102. Instead of the material protrusions 102 there remain welding points 100 at which the clutch disks 14 are connected to the transmitting disk 12 by co-operating with materials. After welding the clutch plates 14 on the transmitting disk 12, the assembly thus produced is cured. This can be done by heating and then by rapidly cooling the assembly. The assembly may be hardened freely or also on a mandrel depending on the hardening distortion to be provided and tolerable, the outer contour of the mandrel corresponding precisely to the gearing 16 of the clutch discs 14. It is thus ensured that the transmission shaft teeth 16 have a desired contour also after curing. The pressure pieces 58 can be mounted in the recesses 46 after hardening, where the base portions 62 engage in the retaining sections 47.25.
