    A receiving cylinder with a pressure joint to which an adapter is connected, which is inserted through an opening in the clutch housing}
    According to the invention the pressure housing comprises a pressure joint which is in close proximity to the hole of the clutch housing. By assembling the pressure joint, the adapter can be connected to the fitting through the clutch housing hole. The assembly position of the pipe fitting produced by the invention has the advantage that the position is not fixed by the pipe joint so that it is not affected at all in the front side position of the clutch housing. In addition, the present invention can be made robust so that the pressure joint does not require any support in the clutch housing. At the same time, the present invention also attaches, on the one hand, the support of the adapter or the support of the pressure joint to the clutch housing as necessary. Since the fittings are in close proximity to the holes in the clutch housing, this can make the adapter dimensions accordingly relatively small and at the same time also advantageous for the tightness of the holes.
    Other forms of the invention are the subject matter of claims 2 to 17.
    According to an advantageous development of the invention the adapter is connected to the fitting of the pressure joint with a plug joint.
    Further contemplated fastening means prevent natural loosening of the adapter. The adapter has a joint projecting along the axial direction in which the adapter is inserted at one end in the form of a receiving portion of the fitting to form a plug connection. Therefore, the joint of the adapter is the inner part and the pipe joint part is the outer front part. Alternatively, the present invention includes the reverse phase of the components constituting the plug connection at the same time, where the fittings are inward and the adapters are outward. Regardless of the type of part that makes up the plug, it remains tight.
    In addition, the present invention includes one plug joint, wherein the inner portion made of synthetic resin to form a stopper joint has a toothed surface structure. The surface structure has a larger dimension than the inner diameter of the accommodating portion, so that the adapter can be loaded and pushed into the accommodating portion. The stopper coupling which secures the adapter by load thus ensures an effective airtightness of the plug joint without the need for a separate seal element. Alternatively, the present invention also includes a distanpiece formed from a pipe section, having a toothed surface structure at both ends, which is pressed into the corresponding receiving hole of the adapter on the opposite side from the assembly position in the receiving hole of the input cylinder. It is considered by the invention as a measure to fix the pressure joint or the fitting according to the position of the adapter. The inner part of the plug joint is provided with a center piece which is engaged in the corresponding groove of the receiving part in the assembled state. The centerpiece then serves to maintain the rotational torque normally when driving the ventilation fan and assembling the adapter. Accordingly, additional support or torsion prevention can be omitted.
    In order to achieve a dustproof binding of the adapter in the pressure joint of the release system or the output cylinder, in accordance with another type of invention, the adapter part and the fitting part forming the plug joint are conical to form a clamping cone or clamping coupling. . In addition to the robust, vibration-free coupling of the adapter, the mutually conical parts can be constantly centered, making this type of clamping cone simple to assemble.
    The present invention also includes screwing as an alternative to plug joints and can be tightened inwardly by the male adapter, in particular.
    As another fastening means for plug engagement, the present invention includes knife edges or shear-rotating engagements. An excellent fastening means between the adapter and the pressure joint is, according to the invention, a spring-loaded coupling. It is also preferred that the plug joint part be a holding lug located in the groove or rear cut-out of the other parts accompanying it in the assembled state. In order to support or reinforce the fastening means, it is also possible to insert an elastic anti-loosing holding clip into the receptacle or to the outer front, extending out radially outwards when inserting any additional parts. When aligned with the annular groove, it is placed on the surface of the insert. As an alternative to elastic holding creep, elastic bolts or elastic pins may also be used as fastening means.
    The shape of the adapter takes into account the fittings which are located at right angles, especially with respect to the fixed position of the pressure joint. At the same time the invention includes fittings at any angle. This type of fitting reduces the radial assembly space when joining the connecting pipe to the adapter forming the extension of the pressure joint.
    According to the invention the adapter comprises an air valve at the same time through which the air contained in the release system can be withdrawn if necessary. The air valve may also be installed at right angles to the adapter longitudinal axis or along the adapter longitudinal axis as needed.
    Another advantageous form of the invention incorporates an auxiliary element, such as an inlet pressure valve maximum torque limiter or a changeover filter, on the adapter, which compensates for the pressure waves generated in the hydraulic system. These auxiliary elements are also connected to the pressure means supply system of the adapter. The combination of these parts facilitates assembly and reduces the number of simultaneous parts.
    Another advantageous measure to reduce assembly costs is to make the adapter an elastic cover cap in accordance with the invention to prevent impurities from penetrating into the clutch housing. The shape and arrangement of this cover cap is also adapted to the holes considered for assembly of the adapter in the clutch housing.
    In order to reduce the cost of mass-producing adapters, the materials are made of resins, especially polymers. Aluminum alloys are particularly suitable as suitable materials for the output cylinders. As an alternative, the output cylinder can also be made of polymer-synthetic resin in order to form a material pair with the adapter.
    It is an object of the present invention to create a release system with a pressure joint that allows simple and economical assembly as an adapter and a secondary connection pipe.
    The present invention relates to a release system, which may also be referred to as an output cylinder or a central release. The release system comprises a piston-cylinder unit fixed concentrically with the drive shaft, which is fixed to the transmission housing and surrounded by the clutch housing. A manual actuating transfer cylinder is installed to actuate the release system, ie pressurize the output cylinder, and is connected to the piston-cylinder unit by a hydraulic circuit. For simple connection of the hydraulic circuit the release system is integral with the pressure joint covering the radial distance between the piston cylinder unit and the clutch housing. At the free end, the pressure joint has a line joint where it can be connected to the hydraulic line.
    One type of release system is shown in US Pat. No. 4,609,087. The housing of such a release system is integral with the pressure joint at the flange surface portion of the transmission housing and thus includes a pressure means supply and a separate air breather channel. The pressure joint also protrudes from the aperture of the clutch housing in the lie connection and the air breather in a fixed position. In the fixed position, the pressure joint is installed in a special circuit of the clutch housing. The clutch housing further has a u-shaped radially inwardly located channel on the front face including the end of the pressure joint. In order to maintain hermeticity, an elastic hermetic element is considered, which is inserted into the clutch housing deeply in the radial direction with respect to the circuit joint of the pressure joint and at the same time in close contact with the u-shape of the channel. The position of the hermetic element allows for the deposition of impurities in the interspace above the clutch housing, which is made between the pressure joint and the wall of the clutch housing. In addition, the two-sealing airtight element must cover the expansion circuit joint of the radial pressure joint and require great care when axially joining the clutch housing to the transmission housing, which entails enormous assembly costs. Known release systems also require expensive clutch housings that are specially shaped for pressure joints.
    The present invention is based on the task of creating a release system having a pressure joint, the circuit joint of which enables simple and economical assembly of the adapter and the secondary joint circuit.
    The first embodiment is described in the drawings to specifically describe the invention, for example, the contents of which are as follows:
    1 is a release system according to the invention
    2 is an enlarged view of a plug joint in which an adapter configured as a joint is inserted into a cylinder mounting portion.
    FIG. 3 is an alternative to FIG. 2 in which an adapter is formed which has an inner cylinder inserted therein.
    4 is a fastening means in the form of a snap joint between the adapter and the cylinder.
    5 is a fastening means which is an alternative form of FIG.
    Figure 6 is a plug joint by knife edge fixing.
    7 is screwed to secure the adapter to the cylinder.

    1 is a hydraulically actuated release system comprising an output cylinder 1 whose press housing 2 is screwed to a transmission housing 3. The output cylinder 1 concentrically arranged around the drive shaft 4 is a pressure joint 5 extending from the compression housing 2 in the radial direction of the unitary body, through which the pressure medium is operated for the operation of the friction clutch. Is passed. The pressure joint 5 corresponds to almost the hole 6 in the clutch housing 7 comprising the friction clutch and the output cylinder 1 at the same time. Due to the rigid construction of the pressure joints 5, these parts do not require any support in the clutch housing 7, which reduces the required assembly costs. The fitting 8 provided at the free end of the pressure joint 5 is useful for installing the adapter 9. The adapter 9 simultaneously forms a simple joint of the multifunction, ie, the connection circuit 10, whereby the pressure medium supply is made from the input cylinder to the output cylinder 1. In addition, the adapter 9 has an air relief valve 11, whereby the air contained in the output cylinder 1 can be discharged. The adapter 9 may additionally comprise an auxiliary element 12, ie a hydraulic pressure valve, a changeover filter or a maximum torque limiter. According to the invention the adapter 9 can also insert more than one auxiliary element 12 if necessary. The adapter 9 has a center projection 13 inserted into the corresponding groove 14 of the fitting 8 as a measure for assembling the pressure joint 5 according to the support direction of the adapter 9. . The adapter 9 is provided with an airtight element 31 for the airtightness of the hole in the clutch housing 7. The hermetic element 31, which is located in the radial groove 32 of the adapter 9, is supported in the assembled state of the clutch housing 7 while closing the hole 6.
    2 to 9 show a detailed "Z" enlarged view of FIG. 1 showing the adapter engagement in various states of the fitting 8.
    The adapter 15a shown in FIG. 2 forms a plug joint 16 with the circuit joint 8 and the adapter 15a as a fitting 8 composed of assembly parts 17 for assembly of the interior 18. The joint is shown integrally and is shown. In order to effectively maintain the air tightness of the plug joint 16a, a seal 19 inserted into the radial groove 20 of the interior 18 and abutting the hole wall 21 of the assembly 17 is used.
    The plug joint 16b formed in FIG. 3 includes a fitting 8 formed of an interior 22 inserted into the assembly 23 of the adapter 15b.
    The adapter 15c shown in FIG. 4 is engaged with the fitting 8 by a plug joint 16a corresponding to FIG. As a fixing means, the adapter 15c further has a snap joint 24a, which includes holder elements 25a and 25b which protrude along the axial direction arranged facing the two adapters 15c. The holder nose (support nose) 26a, 26b which points inward in the radial direction, respectively, at the edge part which was set in the state where the adapter 15c was caught in the back cutting part 27 of 8).
    The spring element 28 is supported at the front of the inner side 18 in order to receive the initial stress of the adapter 15c at the fitting 8, ie to make a frictional connection. In particular, the perforated cup spring-like spring element 28 is in contact with one step 29 of the compression means supply, which is formed at the same time as a stepped hole 30 of the fitting 18.
    Fig. 5 shows the fixing means 24b, wherein the projection 33 located at the front of the fitting 8 is fitted by the projection 34 and the pin along the radial direction of the adapter 15d. The projection 33 extends in the longitudinal direction at the same time and allows the assembly of the support pin 35 outside the clutch housing 7 while protruding through the hole 6 of the clutch housing 7.
    Other fastening means 24c are shear-rotating couplings 36 in FIG. 6, which may be referred to as knife edge connections. The adapter 15e further has an axially oriented corrective support element 38 as a guide lug 39 inwardly radially at the end.
    The shape of the guide lug 39 then coincides with the shape of the axial groove 40 and the radial groove 41. After fixing the adapter 15e, the guide lug 39 is preferentially guided into the axial groove and twisted in the direction of the arrow when reaching the radial groove 41. By the radial groove 41 in the inclined direction, the adapter 15e is moved axially and simultaneously in the axial direction along the fitting 8 direction, with the cushioning element inserted between the fitting 8 and the adapter 15e (37) is pressed. By the shock absorbing element 37, the required initial stress of this part can be achieved, thereby enhancing the function of the fixing means 24c consisting of the shear-rotation coupling 36.
    7 can take a screw joint 42 whereby an adapter 15f is coupled to the fitting 8. In addition, the inside 18 is made of a male screw and is fitted into the screw hole of the assembly portion 17.
    As another alternative for securing the adapter to the fitting, a clamping cone 43 is provided according to FIG. 8. The adapter 15g also has an interior 18 contemplated whose surface forms a cone or cone and fits within the cone of the receiver. The clamping cone 43 acts as a dustproof fixing of the adapter 159 in the circuit joint 8.
    According to the plug joint 16c shown in FIG. 9, the interior 18 of the adapter 15h has a surface sawtooth structure. In particular, the outer circumference of this saw blade-like structure of the adapter 15h made of synthetic resin is excessively larger than the hole wall 21 of the receiving portion 17. The interior 18, which is pressurized into the receiving portion 17 under load, causes deformation of the outer saw blade surface and fits into the jaw wall 21 as a wedge, thereby ensuring the firmness of the adapter 15h in the fitting 8. Ensures a secure, secure, confidential fixation or support. Depending on the assembly method, the plug joint 16c may also be referred to as a stopper joint.
    Useful for hydraulically actuated release systems of friction clutches surrounded by clutch housings for vehicles.
