    PRESSURE PLATE FOR TAC CLUTCH
    The present invention relates to a pressure plate assembly for a wear-compensating friction clutch, in particular a "Travel-Adjusted Clutch (TAC) controlled friction clutch", of a drive train automobile, that is to say, a kinematic chain of a motor vehicle, such as a private car, a truck, a bus or an agricultural utility vehicle, with a plate element realized in one or more parts and provided / configured on at least a first axial end face for frictional engagement with a clutch disc. In addition, the invention relates to a pressure plate subassembly with such a pressure plate assembly as well as a friction clutch having in turn said pressure plate subassembly with the pressure plate assembly. .
    One and more pressure plate assemblies, also referred to as pressure plate arrangements or simply pressure plate, are already generally known according to the state of the art. DE 100 31 598 A1 discloses, for example, a pressure plate for a friction clutch, in which the pressure plate is made substantially annular and divided into a plurality of pressure plate segments successively arranged in the circumferential direction and at least partially movable relative to each other which are held together by a holding device.
    DE 10 2014 218 534 A1 also discloses a pressure plate for a friction clutch which has a cast iron pressure body having a cast iron pressure body having a friction surface to be applied against a clutch disc, as well as a steel cam body having a pressure cam for abutting against an actuating element configured in particular as a disc spring and for moving the pressure plate.
    In addition, it is also known friction friction controlled stroke and take-up of wear / catch-up automatic game for which the structures used are still relatively expensive to manufacture. This is due in particular to the presence of the catching mechanism in question to effect the controlled stroke retraction of the pressure plate assembly in operation. Heretofore, the implementation has most often consisted in that the plate element of the respective pressure plate assembly / pressure plate is made from a single base body or of several partial segments in cast iron. The corresponding ramps of the catching mechanisms are partly introduced into the pressure plate by machining, which has a negative effect on the manufacturing costs.
    It is therefore the object of the present invention to overcome these drawbacks known from the state of the art and in particular to provide a pressure plate assembly for a controlled-stroke friction clutch and automatic play / catch-up adjustment. wear whose manufacture is less expensive.
    According to the invention, this object is achieved in that on the plate element, a metal sheet ramp ring is rotatably mounted on a second axial end face which is diverted from the first end face, said ramp ring having a plurality of individual ramp regions rising in the circumferential direction (and preferably arranged next to each other in the circumferential direction).
    Due to this separate embodiment of the portion having the individual ramps / ramp areas of the pressure plate assembly, the plate member and the ramp contour required for the catch mechanism are made in the form of the ring. to ramps by different elements, and the pressure plate assembly becomes significantly easier to manufacture. On the one hand, the plate member can always be shaped in a minimum of steps, and on the other hand, the sheet metal ramp ring can be formed entirely without machining. The manufacturing costs are thus substantially reduced. Other advantageous embodiments will be explained in more detail below.
    Therefore, it is also advantageous that the ramp ring and / or the pressure plate can be made of a steel material. Most preferably, the pressure plate and / or the ramp ring are manufactured by a continuous casting process. The ramp ring and the pressure plate can thus be made particularly durable.
    In addition, it is advantageous that the ramp ring is attached to the plate member by material contact. A material contact connection further promotes the automated mounting of the ramp ring to the plate member. In this regard, it is particularly useful for the ramp ring to be welded, brazed and / or glued to the plate member. The assembly of the pressure plate assembly is further facilitated.
    In addition or alternatively to the material contact fixing of the ramp ring to the plate member, it is also useful that the ramp ring is attached to the plate member by complementarity of shapes and / or by adhesion. The ramp ring can thus be connected to the plate member in a particularly astute and durable manner depending on the respective use of the plate member.
    In addition, it is advantageous that the individual ramp areas of the ramp ring are made by cold forming, preferably by means of a stamping process and / or a folding process and / or by means of of a cutting process. It is thus possible to manufacture the entire ramp ring particularly easily and without machining.
    If the plate member is further composed of a plurality of individual plate segments, said plate segments being physically separated from each other in the circumferential direction, i.e. said plate segments having substantially separation planes extending in the radial direction, then a pressure plate assembly is made which can be used in a particularly durable manner and which is made particularly resistant to thermal stress. In this regard, it is also useful for the plate segments to be interconnected, preferably by shape complementarity, so that they are movable / displaceable relative to one another (preferably elastically) at least in the axial direction. It is thus possible to compensate in a particularly clever way a temperature difference that occurs during the clutch operation or disengagement of the friction clutch.
    If the ramp ring is fixed integrally in rotation to at least one plate segment or to several plate segments, for example to each plate segment, then there are several ways to mount the ramp ring on the plate. plate element. In this case, it is advantageous that the ramp ring is attached to a plurality of plate segments so that the plate segments are resiliently connected to each other directly by the ramp ring.
    In this case, particularly in the axial direction of the pressure plate assembly, the ramp ring preferably has a lower rigidity than the plate member / plate segments of the plate member. This further improves the efficiency of the pressure plate assembly.
    In addition, the invention relates to a pressure plate subassembly for a friction clutch of an automotive kinematic chain, with a pressure plate assembly according to at least one of the embodiments described above, with a clutch cover connectable to a pressure plate and which is integrally rotatably connected to the plate member, as well as with a controlled stroke take-up mechanism having a ramp counter ring, in which said ramp counter-ring is applied to the ramp ring in the axial direction such that the axial distance of the ramp counter-ring and thus a lever element relative to the first end face of the ring. with ramps can be adjusted by a relative rotation of the ramp counter-ring with respect to the ramp ring. The manufacture of a subset of pressure plate is also possible in a particularly effective manner.
    In addition, the invention relates to a friction clutch for a kinematic chain of a motor vehicle, with such a pressure plate subassembly and a clutch disc disposed in the axial direction between the plate assembly. pressure plate and a pressure plate connected to the clutch cover integrally in rotation. The manufacture of a friction clutch is thus also possible in a particularly effective manner.
    In other words, a sheet pressure plate is thus produced in one or preferably several parts for a travel-adjusted clutch (TAC) friction clutch / controlled stroke, in which the pressure plate (the plate assembly of pressure) is configured in at least two parts and has for example an annular plate body (plate element), made as a sheet metal ring in one or more parts, and a ramp ring. It is also particularly advantageous that the annular friction body (plate element) consists of individual plate segments cut from the sheet, of the same or different type. Each of the plate segments is in the form of a circular arc section and delimited in the circumferential direction of the pressure plate to be manufactured by a first and a second end face. A projection having an outline extends from at least one of the end faces. An adjacent plate segment has on its second end face facing said first end face a complementary contour that said projection engages, the engagement allowing at least partial displacement of the plate segments. On the surface that is diverted from the friction surface, a ramp-shaped counter-ring (ramp ring) made of sheet metal is connected to the annular body integrally in rotation, preferably by material contact. When the friction body is formed by at least two plate segments, the ramp counter-ring connects the plate segments securely at the same time.
    Subsequently, the invention will be described in more detail using figures with a description of exemplary embodiments, including of different type in principle.
    Fig. 1 shows a longitudinal sectional representation of a pressure plate subassembly having a pressure plate assembly according to the invention in a preferred exemplary embodiment, wherein the pressure plate subassembly has been cut at a circumferential zone where two individual ramp areas of the pressure plate assembly are shown in cross-sectional section, Figure 2 shows a longitudinal sectional representation only of the pressure plate assembly according to the invention of FIG. 1, in which a setting ring of a catch mechanism is applied against the pressure plate assembly in the axial direction, FIG. 3 shows a perspective representation of the set of FIG. 4 shows an isometric representation of a pressure plate assembly cut in half in FIGS. longitudinal set according to FIG. 2 with its adjustment ring, FIG. 5 shows a detail representation of a zone of a pressure plate assembly cut in half in the longitudinal direction according to FIG. 4 in a perspective view, where the ramp ring and the adjusting ring are particularly visible at their adjoining ramps; FIG. 6 shows a detailed representation of the area of the already cut-off pressure plate assembly, said zone being 7 is an isometric representation of a ramp ring inserted in the pressure plate assembly of FIGS. 1 to 6, FIG. 8 shows a perspective representation of an arrangement of the pressure plate assembly of FIGS. longitudinally cut ramp ring according to Fig. 7 with a spindle holder for receiving a spindle drive of the catch mechanism, said screw spindle drive cooperating in operation with the adjusting ring for the axial adjustment of the pressure plate, FIG. 9 shows a perspective representation of a section of the ramp ring according to FIG. 7, the ramp ring being cut along a line of section extending in the circumferential direction so that the individual ramp areas are shown in section in the longitudinal direction, FIG. 10 shows a perspective representation of a section of the pressure plate assembly according to FIG. its adjusting ring, in which the arrangement consisting of the pressure plate assembly and the adjusting ring is cut along a circumferentially extending cutting line, so that both the adjustment that the ramp ring are shown in section in the longitudinal direction of their individual ramp areas / ramp zones, Figure 11 shows a rear view of the pressure plate assembly FIG. 2 with its adjustment ring, in which an attachment of the ramp ring to the plate member is here indicated by means of material contact junction areas, and FIG. 12 shows a front view of the Figure 11 of the pressure plate assembly according to Figure 2 with its adjusting ring, in which a first end face of the plate member is visible which cooperates in operation by frictional engagement with a clutch disc of a friction clutch.
    The figures are only of a schematic nature and serve exclusively to understand the invention. The same elements carry the same reference symbols.
    In Fig. 2, a pressure plate assembly 1 of the invention is shown in cross-section in the longitudinal direction / axial direction extending in operation along an axis of rotation about which the pressure plate assembly 1 rotates. The pressure plate assembly 1 is also referred to as the pressure plate or pressure plate arrangement.
    As can be seen clearly in connection with FIG. 1, the pressure plate assembly 1 is intended to be mounted in a pressure plate subassembly 10. When operating, the pressure plate subassembly 10 is a friction clutch, also not shown here for reasons of clarity. In this case, the friction clutch is normally disposed in the flow of moments between an element integral with the output shaft / crankshaft of a combustion engine and a transmission shaft of a kinematic chain. In operation, a clutch cover 11 of this pressure plate subassembly 10 is rotatably connected to a pressure plate / flywheel of the friction clutch. The clutch cover 11, formed in the manner of a housing, forms a cavity 12, in which the pressure plate assembly 1 is housed at least partly in its axial direction. A lever element 8 is also housed in the cavity 12. The lever element 8 in the form of a disc spring is normally pivotally supported / supported by means of a pivot bearing in order to move in operation, in cooperation with an actuating device, also not shown here for the sake of clarity, the pressure plate assembly 1 between an engaged position and a disengaged position. The pressure plate assembly 1 has a substantially annular circumferentially extending circumferential circumferential plate member 2 forming a first axial end face 3. The first axial front face 3 provides a friction surface. In the engaged position, the first axial front face 3 serves for a friction engagement with a clutch disc of the friction clutch, also not shown here for reasons of clarity. The clutch disk is normally integrally connected in rotation to the transmission shaft of the drive train. In an engaged position, the clutch disc is integrally rotatably connected by frictional contact to the pressure plate assembly 1 / the plate member 2 as well as to the pressure plate / flywheel of such whereby a torque from an output shaft / crankshaft of the combustion engine is transmitted to the transmission shaft. In a disengaged position, the pressure plate assembly 1 is instead arranged with respect to the clutch disc such that no torque is transmitted between the output shaft and the transmission shaft.
    In FIG. 2, an adjusting ring / ramp counter-ring 9 of a catch-up mechanism, also not shown for the sake of clarity, is already applied (e) to the pressure plate assembly 1 in the axial direction. The catch-up mechanism used in the pressure plate subassembly 10 is configured such that when the friction clutch operates, the plate member 2 is movable relative to the lever member 8 in the axial direction. . In operation, the catch-up mechanism in cooperation with the pressure plate assembly 1 is used to realize a friction clutch with automatic play / catch-up friction and controlled stroke, called TAC (Travel-Adjusted Clutch).
    In addition to the plate member 2, a ramp ring 6 configured separately from the plate member is provided on the pressure plate assembly 1. The ramp ring 6 is disposed on a second end face 4, axially diverted from the first end face 3, on the plate member 2. The ramp ring 6 is formed of sheet metal 5. The metal sheet 5 is here configured by a steel sheet. The ramp ring 6 is also part of the catch mechanism and cooperates with the adjusting ring 9 in axial displacement of the plate member 2. For this purpose, the ramp ring 6 has several (first) ramp zones. 7 going up in the circumferential direction. As can be seen particularly well in FIG. 2, in operation, these individual ramp zones 7 of the ramp ring 6 are in turn applied against ramp counter-zones 14 of the adjusting ring 9, which is configured complementary to the individual ramp areas 7 and thus also called second individual ramp areas. The ramp counter-zones 14 and the individual ramp zones 7 are then side by side and are adapted to each other so that during a relative rotation of the adjusting ring 9 relative to the ring to ramps 6 during a catching operation, an axial displacement of the plate member 2 occurs relative to the adjusting ring 9. In particular during a rotation of the adjusting ring 9 in a certain (first ) direction of rotation with respect to the ramp ring 6, a distance from the first end face 3 with respect to the adjusting ring 9 increases. Since the adjusting ring 9 in turn is applied in the axial direction against a fulcrum 24 spaced radially with respect to the pivot bearing 13 of the lever member 8, therefore the pivoting position of the lever element 8 with respect to the pressure plate assembly 1 / at the clutch cover 11 is also adjusted. In particular, this catch-up also modifies the axial distance between the lever element 8 / the fulcrum 24 and the first end face 3.
    Depending on the realization of the friction clutch in TAC form, the catch mechanism also has a screw-spindle drive, also not shown here for the sake of clarity, which, as shown in Figure 8, is disposed outside the ring ring in the radial direction and drives through a spindle shaft disposed on a spindle holder 15 the adjusting ring 9 in rotation for catching up. In other embodiments, the spindle carrier 15 is integrated in the ramp ring 6, i.e. the spindle carrier 15 and the ramp ring 6 are composed of a common element. made together integrally of the same material.
    The centering of the adjustment ring 9 is effected by tabs formed from the ring with ramps 6 or adjacent elements, the centering is also not shown here for the sake of clarity. Centering is also possible by additional elements.
    Since it is made in the form of metal sheet 5, as can be seen separately particularly well also in Figures 7, 9 and 10, the ramp ring 6 is entirely manufactured by cold forming. In this case, as can be seen particularly well in FIG. 7, the individual ramp zones 7 as such are all shaped in the same way. They are preferably carried out by means of a stamping process step. Viewed in the circumferential direction of the ramp ring 6, the individual ramp areas 7 are spaced a certain distance apart. In this zone of spacing between two individual adjacent ramp zones 7 in the circumferential direction, a cut-through hole 16 is configured. In particular, the ramp ring 6 is made from a weldable steel material.
    As can also be seen in FIG. 11, the ramp ring 6 is attached to the plate member 2 at a plurality of junction regions 17 distributed in the circumferential direction. In this case, these junction areas 17 are implemented by means of welded joints so that the ramp ring 6 is attached to the plate member 2 by material contact. However, alternatively or additionally, other connection techniques are in principle also usable. For example, in addition or alternatively to the weld, it is also possible to fix the ramp ring 6 to the plate member 2 by means of a glued joint, a brazed joint and / or a connection by adhesion and / or complementarity of shapes. In this exemplary embodiment, an inner marginal zone 18a and an outer marginal zone 18b of the ramp ring 6 which extend respectively in the radial direction are welded to the plate member 2.
    In addition, as can also be seen in Figures 3 to 6 as well as in Figure 12, the plate member 2 is configured in several parts. Alternatively, the plate member 2 may also be configured as a continuous one-piece ring. The plate member 2 of the present exemplary embodiment has several, here six, individual plate segments 19, i.e. separated at the material level. The plate segments 19 are in particular separated from each other in a radial plane extending from the pressure plate assembly 1. All the plate segments 19 are formed as identical parts. According to Fig. 12, each plate segment 19 has on a first clockwise facing side 20 a protrusion 21 extending in the circumferential direction and protruding from the plate segment 19 in the circumferential direction. Viewed in the circumferential direction, the projection 21 is attached to a base portion 25 in the form of a circle segment of the plate segment 19 and configured in principle in the form of bone. In order to accommodate the projection 21 of the plate segment 19 respectively adjacent by complementarity of shapes, the plate segment 19 has in turn on a second face 22, diverted from the first face 20 in the circumferential direction, a recess 23 made so that complementary to the projection 21. In operation, the projection 21 of the adjacent plate segment 19 engages in this recess 23 by complementary shapes so that the plate segments 19 seen in the circumferential direction are firmly connected to each other by producing a annular chain. The projection 21 extends in the circumferential direction to create a distance between the first and second faces 20 and 22 of two adjacent plate segments 19. The first common front face 3 in the form of the friction surface is thus made overall by all the plate segments 19.
    To complete, it should be noted that in FIG. 11 the junction areas 17 are shown schematically only so that the ramp ring 6 is connected through the junction zone 17 only to one plate segments 19 by material contact. In fact, however, when the pressure plate assembly 1 operates, further junction areas 17 are provided, so that the ramp ring 6 at different plate segments 19, especially all segments, is mounted / fixed via respectively at least one or more junction areas 17 to each plate segment 19 integrally rotated (by material contact).
    In this case, the individual plate segments 19 are made of a steel material. However, seen in the axial direction, they are configured to be significantly thicker than the ramp ring so that they are stiffer than the ramp ring 6. Therefore, the ramp ring 6 forms on the other hand because of its higher elasticity in comparison with the individual plate segments 19 an elastic connection in the axial direction of the individual plate segments 19 between them. The plate segments 19 are further realized by means of a cutting process in a thick steel sheet.
    In other words and contrary to the known TAC, in the embodiment according to the invention, no complex and expensive ramp geometry to be manufactured is milled in a cast iron pressure plate, but the cast iron element is even completely omitted. The pressure plate according to the invention (the pressure plate assembly 1) is replaced by a segmented pressure plate 1 of steel. There are modifications. The connection of the pressure plate segments 19 is not implemented as hitherto by a welded cam ring but by means of a so-called ramped sheet (ramp ring 6). In this case, this sheet 6 is welded. The ramp sheet 6 serves to receive the adjusting ring 9 and assists in the known wear compensation of the TAC. According to the invention, the pressure plate segments 19 are connected by the ramp ring 6. The ramp ring 6 is a sheet metal part in which is reproduced the ramp contour (first individual ramp zone 7) for the catching up of wear. In this case, the ramp ring 6 is welded, but it can also be securely connected to the pressure plate segments 19 by gluing, riveting or other means. The centering of the adjustment ring of the TAC 9 may also be effected by tabs formed from the ramp ring 6 or adjacent elements. Centering is also possible by additional elements. Other possibilities for saving in manufacturing costs in comparison with the current series would be to integrate the spindle holder 15 of the known TAC with the ramp ring 6, i.e. the spindle holder 15 and the ramp ring 6 are then composed of one and the same element. 1 pressure plate assembly 2 plate element 3 first end face 4 second end face 5 metal sheet 6 ring with ramps 7 individual ramp area / first individual ramp area 8 lever element 9 adjusting ring / counter ring with ramps Pressure plate subassembly 11 clutch cover 12 cavity 13 pivot bearing 14 counter ramp zone / second individual ramp zone 15 spindle holder 16 through hole 17 junction area 18a inner marginal area 18b marginal area outer 19 plate segment 20 first face 21 projection 22 second face 23 recess 24 fulcrum 25 basic portion
