FIG. 1
Full Text The invention relates to a housing for a release bearing which is intended for a disengaging clutch which is used in vehicles. The hollow-cylindrical housing which is manufactured from plastic encloses a drive shaft in the installed state, which drive shaft connects an internal combustion engine to a change speed gearbox. The housing can be displaced axially by means of a release lever and, on the outside, has an annular flange which is connected integrally to the housing. The annular flange is assigned a release lever on a first end side and the release bearing on the second end side.
Background of the Invention
The housing for a release bearing forms a transmission element for the actuating device of the disengaging clutch, which actuating device makes a gear change of the change speed gearbox possible. In order to simplify the assembly, concepts are known, in which the release bearing can be preassembled captively with the housing. This measure shortens the assembly times on the assembly line, for example for passenger car production, and ensures an assignment of the components •release bearing and housing which is important for the function, or makes automated assembly possible. Furthermore, the captively secured arrangement of the release bearing on the housing avoids faulty assembly or a risk of mistakes.
The laid open specification DE 28 30 249 shows a housing which is assigned a release bearing. A holding plate and a disk spring which are connected via a plurality of fastening means on the outside serve to

rrange the release bearing captively on the housing. To this end, the disk spring has a tab, in the cutout of which a hook of the washer latches. Disadvantageously, at least the holding element encloses the annular flange of the housing directly, with the result that tension is produced in the event of different coefficients of thermal expansion between the components which interact directly.
FR 2 304 826 Al has disclosed an axially displaceable housing for actuating a disengaging clutch, which housing is connected to a release bearing. For the captive arrangement of the release bearing, the annular flange of the housing is enclosed by a sleeve which extends on one side axially over the release bearing and positions the release bearing by means of a rim which is directed radially inward.
Summary of the Invention
The invention is based on the problem of realizing permanent, effective fastening of the housing in conjunction with the release bearing and the flange which is intended for the release lever, these components being manufactured from different materials.
This object is achieved by the features of claim 1.
According to the invention, a housing which is manufactured from plastic is combined with a flange made from steel, on which the release lever is supported in the installed state. According to the invention, the flange is provided with a rim sleeve which is guided with play on the cylindrical section of the circumferential surface of the housing. In order to achieve rotationally secured fastening, the flange of the rirn sleeve is connected to the annular flange of the housing in a form-fitting manner without play in
the circumferential direction and exhibiting play in the radial direction. Captive fastening of the rim sleeve on the housing is achieved by means of a holding plate which engages around the outside of the annular flange and the flange of the rim sleeve. Here, the holding plate is positionally fixed on the annular flange in each case exhibiting radial play and being free of play in the circumferential direction. Furthermore, the release bearing is supported on a radial supporting surface of the holding plate with a force-transmitting connection and is positioned at the same time.
The construction according to the invention makes the combination of a plastic housing with a steel flange and a holding plate which is manufactured from metal sheet possible for a release apparatus. Here, these components are fastened without clamping or an impermissibly large guidance play. As a result of the assignment which is without play in the circumferential direction and exhibits play in the radial direction, components made from different materials and having deviating coefficients of thermal expansion can advantageously be combined to form one structural unit. At the same time, the required expenditure for configuring tools, in particular with regard to the manufacture of the plastic housing, is reduced by fastening all the individual parts according to the invention.
A captive structural unit which comprises the housing, the rim sleeve, the holding plate and the release bearing can be realized with the invention. The construction according to the invention of all the components which are connected to the housing, that is to say the rim sleeve, release bearing and holding plate, are advantageously connected to one another captively in such a way that even different
coefficients of thermal expansion of materials of individual components are compensated for. The type of fastening between the components which are manufactured from steel, the rim sleeve and the holding plate as well as the plastic housing advantageously has no negative influence on the guidance play between the hole of the housing and the stationary guide sleeve which is preferably manufactured from steel. Furthermore, the construction according to the invention of the housing including all associated components makes it possible that an impermissible guidance play between the housing and the guide sleeve does not occur in the operating state as a result of the different operating conditions or loadings and the temperature variations over the entire service life of the disengaging clutch.
Further advantageous refinements of the invention are the subject matter of dependent claims 2 to 16.
Effective rotational securing between the rim sleeve and the annular flange of the housing which is manufactured from plastic is advantageously achieved by means of an axially oriented projection on the annular flange, which projection engages into a corresponding recess of the rim sleeve flange.
As an alternative, the invention includes a rotationally secured installation position of the rim sleeve with respect to the housing, by the flange of the rim sleeve having at least one bump or latch which is configured as a fixing cam and latches with a form-fitting connection, that is to say without play in the circumferential direction and exhibiting radial play, into an associated cutout of the annular flange of the housing.
The design of the rotational securing means preferably comprises axial projections or bumps which are arranged multiply distributed over the circumference between the rim sleeve? and the flange of the housing. The axial projections or bumps which interact in each case with associated recesses or cutouts ensure a centered installation position of the rim sleeve with respect to the housing.
Irrespectively of the design of the measures to achieve a fixed, rotationally secured connection of the components, rim sleeve and housing, the walls of the recesses, bumps or the cutouts in the flange of the rim sleeve or the annular flange of the housing extend parallel to a center line which is oriented centrally. This ensures that, on account of different rates of expansion, caused by different coefficients of thermal expansion between the housing made from plastic and the rim sleeve made from steel, these components can expand in an unimpeded manner, without a negative effect on the guidance play between the housing hole and the guide sleeve.
The projection of the annular flange or alternative bumps on the flange of the rim sleeve are in each case provided with a play "Si, s2" radially on the inside and radially on the outside, in order that the rim sleeve and the annular flange of the housing can be displaced independently of one another on account of different rates of thermal expansion.
The invention includes what are known as coordinating ribs as a measure, with which firstly unimpeded expansion is ensured and secondly no disadvantageous, excessively large installation clearance is set, together with an undesirable development of noise. Here, these are local elevations which extend in the radial direction and are, for example, punctiform, or
local radial ribs which are elastically deformable. Coordinating ribs of this type are preferably likewise arranged on the circumferential surface of the housing, locally in a radial zone, in which the cylindrical section of the rim sleeve is supported in the installation position.
A further refinement of the invention relates to the fixing of the holding plate with respect to the annular flange of the housing. In this regard, it is possible to provide the holding plate with a bump which is configured, for example, as a fixing lug and engages into a corresponding recess of the annular flange, which recess is configured in the manner of a blind hole. The holding plate is preferably provided with a plurality of symmetrically arranged fixing lugs on the side which faces the release bearing. In the installation position, the fixing lugs are in each case inserted into the recesses with a play which is provided radially on the inside and radially on the outside, which recesses ensure an unimpeded, material-induced expansion which deviates from one another between the holding plate and the annular flange of the housing. The holding plate is preferably manufactured without cutting by a deep drawing process and engages around the annular flange of the housing as far as possible. In the installation position, the holding plate forms a rim which is directed radially inward, is oriented in an offset manner parallel to the supporting surface for the release bearing, and positions the flange of the rim sleeve, which flange is supported axially on the annular flange.
Moreover, the holding plate is provided integrally with a U-shaped receptacle which is mounted ahead of the supporting surface for the release bearing, into which receptacle a limb of the rotationally fixed bearing ring of the release bearing engages. The U-shaped
receptacle is wider than the limb and makes installation of a disk spring possible, which disk spring is supported between an annular rim of the receptacle and the limb of the rotationally fixed bearing ring of the release bearing, in order to achieve force-transmitting contact of the bearing ring limb.
As an alternative measure, with which rotationally secured fastening of the rim sleeve with respect to the housing can be achieved, the invention includes two radial attachments which emerge from the cylindrical circumferential surface of the housing, lie opposite one another and form surfaces on the outside which extend parallel to one another. Accordingly, a rim sleeve which is manufactured by a deep drawing process encloses the radial attachments of the housing and therefore achieves an effective, rotationally secured installation position of the rim sleeve.
The attachments are advantageously provided in the radial direction, in the contact region of the rim sleeve, with elastic coordinating ribs which ensure tolerance compensation between the housing and the rim sleeve and, furthermore, make unimpeded, temperature-induced expansion which deviates from one another possible between the rim sleeve and the housing.
The housing, the rim sleeve and/or the holding plate are preferably provided with integrally formed key faces which bring about effective rotational securing with respect to the attachment components and prevent an impermissible play from occurring over the service life. In addition or alternatively, furthermore, beads or bumps are possible, with which the flange of the rim sleeve or the annular flange of the housing engage and make further securing possible, or relieve the
alternative measures for rotational securing in the operating state.
As a result of the construction according to the invention which includes a housing manufactured from plastic and components manufactured in each case from steel, the rim sleeve and the holding plate, the latter are combined to form one structural unit by means of the measures according to the invention. Furthermore, this structural unit can be combined with a release bearing which, combined likewise in a captively secured manner with the other components, forms a release unit which can be preassembled, in order to reduce the required assembly expenditure, in particular for automated assembly.

Detailed Description of the Drawings
The sectional illustration according to figure 1 shows a release apparatus 1 for actuating a disengaging clutch, of which in figure 1 a disk spring 2 is shown partly which is supported on a release bearing 3 with a force-transmitting connection. The release apparatus 1 can be displaced in the arrow direction by means of a release lever 4, the force of the disk spring 2 automatically displacing the release apparatus 1 into the initial position, as soon as the actuating force of the release lever 4 is canceled. The release apparatus 1 comprises a hollow-cylindrical housing 5 which is manufactured from plastic and is guided on a guide sleeve 7 with a guidance play 6. The guide sleeve 7 encloses a drive shaft 8 in a radially spaced-apart manner, which drive shaft 8 connects an internal combustion engine to a change speed gearbox, the guide sleeve 7 being fastened in a stationary manner, preferably to a housing of the change speed gearbox.
The housing 5 is provided integrally with an annular flange 9 which is directed radially outward and on which a flange 10 of a rim sleeve 11 is supported in a manner which is directed toward the release lever 4. The annular flange 9 and the flange 10 are surrounded on the outside by a holding plate 12 which positionally fixes the flange 10 with a radially inwardly directed
rim 13 and forms a U-shaped receptacle 14 on the opposite side of the annular flange 9. On a radial supporting surface 15 with a large surface area, the release; bearing 3 is supported in a rotationally fixed manner via a radial limb 16 of an outer bearing ring 17. Furthermore, a disk spring 18 is inserted into the U-shaped receptacle 14 which is delimited on the end side by an annular rim 19, which disk spring 18 ensures force-transmitting support of the limb 16 on the radial supporting surface 15 of the holding plate 14. The disk spring 2 of the disengaging clutch is supported directly on the inner circumferential bearing ring 20 of the release bearing 3.
On the radial supporting surface 15, the holding plate 12 which is manufactured without cutting by a deep drawing process has at least two fixing lugs 21 which are arranged spaced-apart radially and engage with play into associated recesses 22 of the annular flange 9 with a form-fitting fit. The holding plate 12 is advantageously provided with a plurality of fixing lugs 21 which are arranged distributed over the circumference and latch into corresponding recesses 22. For the; rotational fixing of the rim sleeve 11 with respect to the annular flange 9, the flange 10 of the rim sleeve 11 has at least one cutout 23, into which an axial projection 24 of the annular flange 9 is fitted with play. The housing 5 which is manufactured from plastic is assigned the components rim sleeve 11 and holding plate 12 which are both manufactured from steel or steel sheet, that is to say these components have coefficients of thermal expansion which deviate from one another. In order to compensate for this different thermal expansion, the fixing lugs 21 engage into the associated recesses 22 of the annular flange 9 with radial play on both sides.
Figure la shows an enlarged illustration of the cutout 23 which has walls 25a, 25b which extend parallel to one another, are directed centrally, and into which the projection 24 engages with a radial play "Si, s?" on both sides. The projection 24 is provided on both sides in the circumferential direction with coordinating ribs 26a, 26b. In this way, a connection which is also constantly adjusted in the radial direction is produced between the projection 24 and the flange 10, the coordinating ribs 26a, 26b making positioning of the projection 24 with respect to the cutout 23 without play possible by melting when they are joined together. As an alternative, it is possible to assign coordinating ribs to the flange 10 within the cutout 23, which coordinating ribs point radially in the direction, of the projection 24 and make coupling without play possible by melted buried portions in the flange 10.
The housing 5, on the circumferential surface 27 of which the cylindrical section of the rim sleeve 11 is guided with play, has radially outwardly directed coordinating ribs 28. The installation clearance 29 which is required for functional reasons between the rim sleeve 11 and the housing 5 is compensated for by the coordinating ribs 28. In this way, a defined installation position of the rim sleeve 11 is set with respect to the housing 5, which defined installation position avoids rattling noises and therefore disadvantageous noise generation. Moreover, the elastically configured coordinating ribs 28 make it possible for the housing 5 to expand in an unimpeded manner as a result of heat, without having an influence on the guidance play 6 between the housing 6 and the guide sleeve 7.
Figure 2 shows the release apparatus 1, in which the rim sleeve 11 is fastened to the housing 5, as an
lternative to figure 1. The remaining construction of the release apparatus 1 is identical to the release apparatus which is shown in figure 1. The flange 10 of the rim sleeve 11 has a bump 30. The axially protruding fixing lug engages into a corresponding cutout 31 of the annular flange 9 of the housing 5 with a form-fitting connection but exhibiting play.
Figure 2a shows the interaction of the bump 30 in conjunction with the cutout 31 in an enlarged illustration. In the installation position, the bump 30 is provided with a radial play "Si, 82" on both sides. Coordinating ribs 32a, 32b are provided to constantly bridge the installation clearance, which coordinating ribs 32a, 32b are provided as an alternative in the circumferential direction on the bump 30 or the wall of the cutout 31 of the annular flange 9.
Figure 3 shows the housing 33 which is assigned the guide sleeve 34. As a measure for achieving effective rotational securing, the housing 33 is provided with two attachments 35a, 35b which lie opposite one another and emerge from the circumferential surface 27 of the housing 33. Here, the guide sleeve 34 which is manufactured without cutting by a deep drawing process encloses the attachments 35a, 35b and is supported here on the side surfaces 36a, 36b of the attachments 35a, 35b. An expansion gap 39 is provided between the surfaces 43a, 43b of the attachments 35a, 35b and the guide sleeve 34, in which expansion gap 39 coordinating ribs 38 are provided which are arranged locally, are connected integrally to the housing 33 or the guide sleeve 34 and can be melted.
As an addition to figure 3, figure 4 shows the holding element 40, to which the rim sleeve 34 is fastened in a manner which is secured against displacement with respect to the housing 33. For this purpose, the
housing 33 is provided with integrally formed key faces 41 which are intended for the holding element 40. In this way, a permanent arrangement of the guide sleeve 34 with respect to the housing 33 is ensured over the service- life of the disengaging clutch or the release apparatus 1. A component which is shaped from sheet metal is possible as holding element 40, which component has bumps 41, in accordance with the detail "z" shown in figure 4a, which latch into corresponding recesses 42 of the housing 33. Furthermore, the guide sleeve 34 forms two surfaces 43a, 43b which are oriented parallel to one another and delimit an engagement 44a, 44b radially on the inside, which engagements 44a, 44b are delimited on the outside by tabs 45a, 45b of the guide sleeve 34. The engagement 44a, 44b is intended for a release lever 4 which is preferably of fork-shaped design, according to figure 1, of the release apparatus 1.
