Description

[0001] Housing arrangement with concentric slave cylinder and drive module with the housing arrangement

[0002] The invention relates to a housing arrangement with the features of the preamble of claim 1. Furthermore, the invention relates to a drive module with the housing arrangement.

[0003] Slave cylinders are known that serve to transmit an actuating force to a hydraulic clutch unit. In a concentric design, such slave cylinders essentially consist of an annular housing and an annular piston that is axially displaceable within the annular housing and can transmit an actuating force to a clutch. In an installation configuration, the slave cylinder can be arranged in a housing of the clutch unit and sealed against it.

[0004] Document DE 102018104374 B3 discloses, for example, an actuating device for a clutch system of a motor vehicle, with two slave cylinders each designed to actuate a clutch, wherein each slave cylinder has a piston and a housing area that guides the piston in a displacement direction and defines a fluid space together with the piston, and with a supply unit on which the slave cylinders are provided in such a way that a fluid supply channel formed by the supply unit is fluidically connected to the fluid space for each slave cylinder, wherein the housing areas of the two slave cylinders are formed directly by the supply unit.

[0005] It is an object of the present invention to provide a slave cylinder of the type mentioned above, which is characterized by a robust design and particularly high sealing performance. This object is achieved by a housing arrangement with the features of claim 1 and a drive module with the features of claim 10. Preferred or advantageous embodiments of the invention will become apparent from the dependent claims, the following description, and the accompanying figures.

[0006] The invention relates to a housing arrangement with a concentric slave cylinder, also known as a "concentric slave cylinder (CSC)." In particular, the slave cylinder serves to transmit a force and / or movement to a coupling device in order to open or close the coupling device. The coupling device can be designed as a friction clutch, preferably a multi-plate clutch, or a positive-lock clutch, preferably a jaw clutch. Alternatively, the slave cylinder can also be designed and / or suitable for actuating a brake device, in particular a friction brake. The slave cylinder is preferably hydraulically actuated.

[0007] The slave cylinder has an annular housing which includes a pressure chamber circling a main axis and at least or exactly one axial fluid connection opening fluid-fluidically connected to the pressure chamber. In particular, the pressure chamber is formed by an annular space circling the main axis, which is preferably open in one axial direction and closed in the opposite axial direction. In principle, the annular housing can have only one fluid connection opening. Alternatively, the annular housing can have several fluid connection openings distributed around the main axis and / or evenly spaced. The annular housing preferably has a central through-opening, in particular a bore, through which at least or exactly one shaft can pass in an installed position of the slave cylinder. Preferably, the main axis is defined by an axis of rotation of the shaft.

[0008] The slave cylinder has an annular piston which is axially movable within the annular housing and defines the pressure chamber in an axial direction with respect to the main axis. In particular, the annular piston serves to transmit an actuating force to the clutch or brake device. Specifically, the actuating force is to be understood as a compressive force directed axially with respect to the main axis. Preferably, the annular piston is rotationally symmetrical with respect to the main axis. Preferably, the annular piston and the annular housing are arranged coaxially and / or concentrically with respect to the main axis. The pressure chamber can be filled with and / or is filled with an operating medium. When the slave cylinder is actuated, the fluid pressure on the operating medium increases, whereby the actuating force is generated due to the increasing fluid pressure in the pressure chamber and transmitted to the annular piston, so that it is axially disengaged.In particular, the operating medium is a hydraulic fluid, specifically a hydraulic oil. The slave cylinder can have an inner and an outer piston seal, which are designed and / or suitable for sealing the pressure chamber. In particular, the outer and / or inner piston seal is formed by a piston sealing ring, which bears radially against the ring housing during piston movement, preferably permanently and / or fluid-tight.

[0009] The housing assembly comprises a housing section with a receiving area and a fluid connection, wherein the annular housing is received in the receiving area and fluidically connected to the fluid connection via the fluid connection opening. In particular, the housing section is designed as a coupling housing, e.g., a coupling bell. The receiving area is preferably formed by a cylindrical opening, recess, depression, or the like, in which the annular housing is at least partially or completely received. Specifically, the receiving area has a central through-opening through which the at least one shaft passes. The fluid connection is particularly preferably arranged opposite and / or aligned with the fluid connection opening in the housing section, preferably an intermediate wall. The fluid connection can be designed as a bore extending axially with respect to the main axis.Furthermore, the slave cylinder has a sealing device by which the annular housing is supported in an axially opposite direction to the main axis against the housing section, sealing a fluid connection between the fluid port and the fluid port opening from the environment. The sealing device is preferably designed as a static seal. In particular, the sealing device serves to seal the annular housing against the housing section in the area of ​​the fluid port opening in a fluid-tight manner, thus preventing fluid leakage between the annular housing and the housing section. In other words, the sealing device seals the annular housing and the housing section in the area of ​​the fluid port against the environment. Fluid can therefore flow into and out of the pressure chamber via the fluid port to actuate the slave cylinder.

[0010] Within the scope of the invention, it is proposed that the ring housing be subjected to an axial contact force at its outer diameter in the axial opposite direction, by which the ring housing is pressed against the sealing device, wherein the ring housing is stiffened, at least in sections, to reduce bending stresses. In particular, the contact force ensures a sealing contact of the sealing device with the housing section and simultaneously fixes the ring housing in the receiving area. Specifically, the stiffening provides resistance against elastic deformation of the ring housing caused by the axial contact force. In principle, the stiffening can be formed by a stiffening structure integrated into the ring housing. Preferably, however, the stiffening is formed by one or more separate stiffening elements.The stiffening can be arranged or formed in the force transmission path, in particular between force introduction and force transmission.

[0011] The invention is based on the understanding that the axial contact force acting on the sealing device via the ring housing makes a significant contribution to the tightness. If this axial contact force is insufficient, leakage can occur. If the axial contact force is too high, the housing can bend, which can lead to fatigue fracture of the ring housing. The advantage of the invention is that the ring housing is protected against high bending loads by the stiffening, and the sealing device can be subjected to very high contact forces. This guarantees the tightness of the assembly and prevents damage to the ring housing.

[0012] In a specific embodiment, the ring housing is made of plastic and stiffened by reinforcement. Specifically, reinforcement is understood to mean at least one stiffening element that stiffens the plastic against the contact force or along the force transmission path. In principle, a sleeve or ring surrounding the ring housing can be used as reinforcement, which is fixed to the ring housing by frictional or form-fit connection. Alternatively, an insert can also be used as reinforcement, which is overmolded with the plastic during the manufacturing process of the ring housing. Thus, a ring housing is proposed which, due to the reinforcement, possesses improved component stiffness for the plastic ring housing.

[0013] In a more detailed specification, the reinforcement is formed by a reinforcing sleeve embedded in the plastic. In other words, during the injection molding process, a sleeve-shaped reinforcement is integrated into the wall thickness of the ring housing, particularly at one or more outer surfaces of the housing. The reinforcing sleeve is preferably manufactured without machining, most preferably by stamping or stamping-bending. Specifically, the reinforcing sleeve is manufactured using forming techniques and / or adapted to the geometry of the ring housing. Thus, a reinforcement is proposed that enables large-area reinforcement, preferably over the outer circumference of the ring housing.

[0014] In a further specification, it is stipulated that the reinforcement is a steel reinforcement. Specifically, the reinforcement is designed as a reinforcement sleeve made of a steel alloy, preferably a sheet metal sleeve. Thus, a reinforcement is proposed that can be manufactured cost-effectively and also provides a high degree of stiffening of the ring housing.

[0015] In a specific embodiment, the pressure chamber is bounded radially by an outer and an inner cylinder section and axially by a wall section containing the fluid connection opening. The axial contact force is transmitted to the wall section via the outer cylinder section, and at least the outer cylinder section and the wall section are stiffened. In principle, the contact force can be introduced directly into the cylinder section in the axial direction, so that the cylinder section is subjected to a compressive load and the wall section to a bending load. Preferably, however, the contact force acts on the cylinder section offset in the radial direction, so that both the cylinder section and the wall section are subjected to a bending load.The wall section preferably extends in a radial plane of the main axis, with the two cylinder sections being integrally formed onto the wall section in the axial direction and / or aligned with the main axis. In particular, the two cylinder sections and the wall section are manufactured in one piece, preferably from a single injection-molded plastic part. Specifically, in an installed position, the wall section rests axially against the sealing device, and the outer cylinder section rests radially against the housing section. Preferably, the outer cylinder section and the wall section have reinforcement, more preferably a reinforcement sleeve. Specifically, the reinforcement or the reinforcement sleeve is formed in one piece and / or extends continuously over the entire cylinder and wall section. In other words, the reinforcement sleeve also has a cylinder section and a wall section.A ring housing is therefore proposed which is characterized by a simple and robust design and also features increased stiffening of the force-transmitting sections.

[0016] In a further development, the ring housing has a flange section extending radially to the outer cylinder section. The axial contact force is transmitted to the outer cylinder section via the flange section, which is also stiffened. In principle, the contact force can act directly on the flange section in the axial direction, subjecting the flange section, as well as the cylinder and wall sections, to bending stress. The flange section allows the contact force to be applied radially offset from the cylinder section, thus providing additional installation space for the ring piston or components operatively connected to the ring piston, such as a release bearing. The flange section preferably extends in a further radial plane of the main axis.Specifically, the flange section is arranged axially spaced from the housing section in an installation situation. In particular, the two cylinder sections, the wall section, and the flange section are manufactured in one piece, preferably from a single injection-molded plastic part. Preferably, the outer cylinder section, the wall section, and the flange section feature reinforcement, more preferably a reinforcement sleeve. Specifically, the reinforcement or the reinforcement sleeve is formed in one piece and / or extends continuously through the entire cylinder, wall, and flange section. In other words, the reinforcement sleeve also comprises a cylinder section, a wall section, and a flange section. Thus, a ring housing is proposed which is characterized by an enlarged installation space and also features increased stiffness of the load-bearing sections.

[0017] In a further specification, the ring housing is provided with an additional cylindrical section extending axially from the flange section, with the axial clamping force being introduced axially into this cylindrical section. Preferably, the clamping force is introduced directly into the additional cylindrical section in the axial direction, so that the additional cylindrical section is subjected to a compressive load and the flange, cylinder, and wall sections are subjected to a bending load. The additional cylindrical section allows the clamping force to be applied axially offset from the flange section, thus providing additional installation space. The additional cylindrical section preferably extends parallel and / or in the same direction as the two cylinder sections. Specifically, in an installation situation, the additional cylindrical section is arranged radially spaced from the housing section.In particular, the three cylinder sections, the wall section, and the flange section are manufactured in one piece, preferably from a single injection-molded plastic part. Preferably, the additional cylinder section has no reinforcement. The cylinder section allows the contact force to be easily applied to the outer diameter of the ring housing.

[0018] In a further embodiment, the housing assembly is provided with a pressure element mounted on the housing section, through which the ring housing is subjected to the axial pressure force. In particular, the pressure element is connected to the housing section in such a way that it applies the axial pressure force to the ring housing at its outer diameter, preferably at the further cylindrical section. The pressure element is particularly preferably connected to the housing section by a positive-locking and / or force-locking connection. For example, the pressure element is designed as an annular pressure disc mounted on an axial end face of the housing section. Alternatively, the pressure element can be designed as an annular press-fit disc pressed into the receiving area of ​​the housing section.The pressure element ensures that the contact force is distributed evenly across the ring housing, thus guaranteeing a tight seal between the wall section and the sealing device. Furthermore, the pressure element secures the ring housing within the receiving area.

[0019] In a specific implementation, the sealing device is designed as an elastically deformable flat gasket. Specifically, the flat gasket is elastically deformed or subjected to a contact force during installation. The flat gasket is designed as a flat sealing ring, preferably a flat rubber sealing ring. Optionally, the flat gasket can be reinforced and / or encased. The flat gasket must be pre-tensioned with a very high contact force to ensure a high level of sealing. The preferably overmolded stiffener protects the ring housing against high bending loads and allows the flat gasket to be subjected to a sufficiently high contact force.

[0020] A further aspect of the invention relates to a drive module comprising at least or exactly one drive motor, a coupling device, and the housing arrangement as previously described. In particular, the drive module is connected to a transmission device, whereby a torque path between the drive motor and the transmission module is influenced when the coupling device is actuated. The drive motor is preferably an electric motor. Optionally, the drive module is connected to another drive motor, e.g., another electric motor or an internal combustion engine, whereby a torque path between the drive motor and the other drive motor is influenced when the coupling device is actuated. In simplified terms, the coupling arrangement serves selectively to couple the drive motor to the transmission device or to the other drive motor.The transmission device can be designed as a stepped automatic transmission, a dual-clutch transmission, or a continuously variable transmission (CVT). The clutch device can therefore be a disconnect clutch (CO) or a dual clutch (C1 / C2) of an electric or hybrid powertrain.

[0021] Further features, advantages, and effects of the invention will become apparent from the following description of preferred embodiments of the invention. These include:

[0022] Fig. 1 shows a schematic representation of a housing arrangement with a slave cylinder as an embodiment of the invention;

[0023] Fig. 2 shows a schematic representation of a drive train with the housing arrangement described in Figure 1. Figure 1 shows a housing arrangement 1 with a housing section 2 and a concentric slave cylinder 3, abbreviated CSC, which is arranged coaxially and / or concentrically to a main axis 100 in a receiving area 4 of the housing section 2.

[0024] The slave cylinder 3 has a ring housing 5 and a ring piston 6 received in the ring housing 5, which is axially movable relative to the ring housing 5 with respect to the main axis 100. The ring housing 5 and the ring piston 6 are arranged coaxially and concentrically with respect to the main axis 100.

[0025] The annular housing 5 and the annular piston 6 define a pressure chamber 7 that rotates around the main axis 100. This pressure chamber is bounded with respect to the main axis 100 in an axial direction 101 by the annular piston 6 and in an axial opposite direction 102 by a wall section 8 of the annular housing 5. It is bounded in a radial direction 103 by an outer cylinder section 9 and in an radial opposite direction 104 by an inner cylinder section 10. To seal the pressure chamber 7, the slave cylinder 3 has an outer and an inner piston seal 11, 12. The annular piston 6 seals against the outer cylinder section 5 in the radial direction 103 via the outer piston seal 11 and against the inner cylinder section 10 in the radial opposite direction 104 via the inner piston seal 12.

[0026] Here, the outer piston seal 11 is securely held in an outer seal receptacle 13, and the inner piston seal 12 is held in an inner seal receptacle 14. For example, the outer seal receptacle 13 is designed as an annular groove arranged on the outer circumference of the annular piston 3, and the inner seal receptacle 14 is designed as an annular groove arranged on the inner circumference of the annular piston 3. Both piston seals 11 and 12 are each designed as a dynamic elastomer seal, in particular as a groove seal ring. The housing section 2 and the annular housing 5 each have a central through-opening 16 or 17, which are aligned axially with respect to the main axis 100 and / or coaxial to each other. In an installation configuration, a shaft 15 passes through the two through-openings 16 and 17. For example, the main axis 100 is defined by an axis of rotation of the shaft 15.The through-opening 16 of the housing section 2 is arranged in an intermediate wall 18, which extends in a radial plane of the main axis 100 and limits the receiving area 4 in the axial opposite direction 102.

[0027] To fill the pressure chamber 7 with a fluid, the ring housing 5 has a fluid connection opening 19 provided in the wall section 8, through which the pressure chamber 7 can be supplied with fluid via a fluid connection 20 arranged in the intermediate wall 18. For example, the fluid is a hydraulic fluid, preferably a hydraulic oil.

[0028] The housing assembly 1 has a sealing device 21, which is arranged axially between the annular housing 5 and the housing section 2 to seal the fluid connection between the fluid port 20 and the fluid port opening 19 from the environment. The sealing device 21 is designed as a static elastomer seal, in particular as a flat sealing ring, by means of which the annular housing 5 is supported circumferentially against the housing section 2 in the axial direction 102. The sealing device 21 bears against the wall section 8 in the axial direction 101 and against the intermediate wall 18 in the axial direction 102.

[0029] The sealing device 21 has at least one opening 22, which is arranged overlapping or aligned with the fluid connection 20 and the fluid connection opening 19 in order to connect them fluidically. The slave cylinder 3 also has a pressure element 23, via which the ring housing 5 is subjected to a pressure force 105 in the axial opposite direction 102 towards the intermediate wall 18. The pressure force 105 fixes or presses the ring housing 5 into the receiving area 4 and simultaneously presses the sealing device 21 against the intermediate wall 18. To disengage the annular piston 6 from the annular housing 5 in the axial direction 101, fluid is supplied into the pressure chamber 7 via the fluid connection 20, thereby increasing the fluid pressure in the pressure chamber 7, which acts on the annular piston 6 in the axial direction 101.

[0030] To transmit the contact force 105, the ring housing 5 has a flange section 24 radially formed on the outer cylinder section 9, which extends in the radial direction 103 in a radial plane of the main axis 100. A further cylinder section 25 adjoins the flange section 24 in the axial direction 101 and is aligned with the two cylinder sections 9 and 10. The receiving area 4 has two different diameters 106 and 107, with the outer cylinder section 9 bearing against the housing section 2 within the smaller diameter 106 in the radial direction 103, and the flange section 24 and the further cylinder section 25 being arranged within the receiving area 4 at a distance from the housing section 2 within the larger diameter 107.

[0031] The pressure element 23 rests directly against the further cylinder section 25 in the axial opposite direction 102 in order to introduce the pressure force 105 axially into the cylinder section 25. The pressure force 105 is thereby transmitted via the flange section 24 and the outer cylinder section 9 to the wall section 8. Due to the radially offset force application, the flange section 24, the outer cylinder section 9, and the wall section 8 are subjected to a bending load, which can lead to deformation of the ring housing 5 and thus to fracture over its service life.

[0032] The ring housing 5 is manufactured in one piece from an injection-molded plastic, with the flange section 24, the outer cylinder section 9, and the wall section 8 being stiffened to reduce bending stress. For this purpose, the ring housing 5 has a reinforcement 26, which is embedded in the plastic and reduces the bending stresses. The reinforcement 26 is, for example, designed as a steel sleeve that essentially corresponds to the shape of the wall section 8, the outer cylinder section 9, and the flange section 25. In other words, the reinforcement 26 is formed by a steel sleeve that stiffens the cylinder section 9, with a radially inwardly directed flange stiffening the wall section 8 and a radially outwardly directed flange stiffening the flange section 24. The reinforcement 26, in particular the steel sleeve, can be manufactured, for example, by stamping.

[0033] A ring housing 5 with an overmolded steel reinforcement in the area of ​​the force transmission path is therefore proposed, which protects the ring housing 5 against high bending loads and allows the sealing device 21 to withstand very high forces. This ensures the tightness of the assembly and extends the service life of the ring housing 5.

[0034] Figure 2 shows a drive train 27 for a vehicle, wherein the drive train 27 comprises a drive module 28 with a clutch unit 29 comprising the housing arrangement 1. For example, the housing section 2 forms part of a clutch housing, not shown, of the clutch unit 29.

[0035] The drive module 28 can be designed as a so-called hybrid module, wherein the drive module 28 comprises a drive machine 30 which is coupled and / or can be coupled to another drive machine 31 via the coupling unit 29. For example, the drive machine 30 can be an electric machine and the other drive machine 31 can be another electric machine or an internal combustion engine.

[0036] The coupling unit 29 has a coupling device 32 designed as a disconnect coupling, also called a KO coupling, which is configured to interrupt a drive torque between the two drive machines 30, 31. In a closed state of the coupling device 32, the shaft 15, in particular a rotor shaft, of the drive machine 30 and another shaft 33, in particular another rotor shaft or a crankshaft, of the other drive machine 31 are rotationally coupled to each other and, in an open state, are rotatable relative to each other.

[0037] The slave cylinder 3 serves to actuate the clutch device 32. In certain ferry operations where no propulsion energy is required, such as sailing operations, the slave cylinder 3 can be actuated to open the clutch device 32, thereby decoupling the drive motor 30 or the other drive motor 31, so that no energy is transferred to the wheels 34 of the vehicle and the vehicle continues to roll without actively consuming energy.

[0038] The drive train 1 also includes a transmission device 35, which is connected on the input side to the drive motor 30 and / or the additional drive motor 31, and on the output side to a differential gear 36, whereby a torque generated by the drive motor 30 and / or the additional drive motor 31 is transmitted or translated via the transmission device 35 to the differential gear 36 and thus to the driven wheels 34 of the vehicle. For example, the transmission device 35 can be designed as a dual-clutch transmission.
