Background Art

[0003] The hydraulic brake system of a motor vehicle usually has a plurality of friction brake devices, which are hydraulically connected to the brake master cylinder of the brake system. If the brake master cylinder is operated, the hydraulic fluid is moved into the slave cylinder of the friction brake device, so that the friction brake device generates a friction braking torque. In this case, an operating device is usually provided to operate the brake master cylinder. As the degree of electrification of motor vehicles continues to increase, the operating devices of the brake system are also increasingly electrified. An operating device of the type mentioned at the beginning is known, for example, from the open patent document DE 10 2020 208764A1. The operating device has a transmission device with a movable threaded screw. The transmission device can be driven by an electric motor of the operating device. If the operating device is installed in the brake system as specified, the brake master cylinder can be operated by moving the threaded screw. The operating device also has a housing, which has at least one corresponding rotation stop. The threaded screw is at least partially arranged in the housing. In order to prevent the threaded screw from rotating relative to the housing, an anti-rotation element connected to the threaded screw in a non-rotatable manner is provided.

Summary of the invention

[0004] The operating device according to the invention with the features of claim 1 is characterized in that the housing is an extruded profile and the corresponding rotation stop is formed by an extruded structure of the extruded profile. An extruded profile is a component manufactured by extrusion or extrusion. Without taking into account possible subsequent processing of the extruded profile, the extruded profile has the same cross section over its entire longitudinal extension. The cross section of the extruded profile corresponds in its shape to the opening of the extrusion tool used to manufacture the extruded profile. Extruded profiles can usually be manufactured cost-effectively, so that the manufacturing costs of the operating device can be reduced by configuring the housing as an extruded profile. The extruded structure is a structure of the extruded profile produced by extrusion. A structure suitable for forming the corresponding rotation stop can be easily realized by extrusion. Since the corresponding rotation stop is formed by the extruded structure, no complicated subsequent processing is required to form the corresponding rotation stop. This makes it possible to further reduce the cost of manufacturing the operating device. Particularly preferably, the housing or the extruded profile is made of aluminum. According to the invention, the threaded screw is at least partially arranged in the housing or the extruded profile. Preferably, the threaded screw extends into the housing so that the threaded screw is only partially arranged in the housing. Alternatively, the threaded spindle is arranged in its entirety in the extruded profile. The housing is preferably of tubular construction and in this respect has a surrounding peripheral wall which defines, or more precisely surrounds, the housing interior of the housing. The anti-rotation element is preferably constructed separately from the threaded spindle and is fixed to the threaded spindle. Alternatively, the anti-rotation element is preferably constructed integrally with the threaded spindle. Preferably, the anti-rotation element is arranged at the end of the threaded spindle facing the brake master cylinder.

[0005] According to a preferred embodiment, the displacement axis of the threaded spindle is oriented perpendicularly to the cross section of the extruded profile. This makes it easy to effectively connect the threaded spindle to the brake master cylinder. Preferably, the brake master cylinder is arranged at the end side of the extruded profile.

[0006] According to a preferred embodiment, the transmission device has a screw drive mechanism, wherein the screw drive mechanism has a threaded screw and a rotatably supported screw nut, wherein the screw nut can rotate in a first rotation direction and a second rotation direction opposite to the first rotation direction, and wherein the anti-rotation portion is configured to prevent the threaded screw from rotating in the first rotation direction and the second rotation direction. This design of the anti-rotation portion enables the threaded screw to move in a first direction and a second direction opposite to the first direction along the movement axis according to the rotation direction of the screw nut by rotating the screw nut.

[0007] Preferably, the extruded profile has at least one first corresponding rotation stop oriented against a first rotation direction and at least one second corresponding rotation stop oriented against a second rotation direction, wherein the first corresponding rotation stop cooperates with the first rotation stop of the anti-rotation element, and wherein the second corresponding rotation stop cooperates with the second rotation stop of the anti-rotation element.

Alternatively, the first corresponding rotation stop and the second corresponding rotation stop are preferably part of different extruded structures of the extruded profile. Preferably, the extruded profile has a plurality of first corresponding rotation stops spaced apart from each other in the circumferential direction of the extruded profile and / or a plurality of second corresponding rotation stops spaced apart from each other in the circumferential direction of the extruded profile.

[0008] According to a preferred embodiment, the extruded structure is a groove extending through the extruded profile, and the radial projection of the anti-rotation element radially engages in this groove. On the one hand, the groove extending through the extruded profile can be easily realized technically by extrusion. In addition, the groove is particularly suitable for forming the anti-rotation portion. The first corresponding rotation stop mentioned above and the second corresponding rotation stop mentioned above are preferably formed by different side walls of the groove. Preferably, the groove extends axially through the extruded profile relative to the movement axis of the threaded screw.

[0009] Preferably, the extruded profile has a plurality of grooves extending through the extruded profile, which grooves are spaced apart from one another in the circumferential direction of the extruded profile. Particularly preferably, two grooves are provided, which are diametrically opposite one another.

[0010] Preferably, the counter-rotation stop has a sliding coating. Low-friction guidance of the anti-rotation element and thus the threaded spindle in the extruded profile can be achieved by the sliding coating. For example, the sliding coating is a coating made of plastic, in particular PTFE.

[0011] According to a preferred embodiment, the anti-rotation element has a sliding pad, which forms a rotation stop. Low-friction guidance of the anti-rotation element and thus the threaded spindle in the extruded profile can also be achieved by means of the sliding pad. Preferably, the sliding pad is made of plastic. If the anti-rotation element has a sliding pad, the above-mentioned sliding coating is preferably omitted.

[0012] Preferably, the actuating device has a pressure transmitter which is movably mounted in a penetration of the threaded spindle, wherein the pressure transmitter is connected to an input rod of the actuating device and wherein the master brake cylinder can be actuated by moving the pressure transmitter. The master brake cylinder can thus be actuated both by the electric motor via the threaded spindle and by the input rod via the pressure transmitter. By mounting the pressure transmitter in the penetration of the threaded spindle, a particularly advantageous connection of the pressure transmitter and the threaded spindle to the master brake cylinder can be achieved. In particular, the threaded spindle and the pressure transmitter are arranged or oriented coaxially with a hydraulic piston movably mounted in the master brake cylinder.

[0013] According to a preferred embodiment, the peripheral wall of the extruded profile has a flat first mounting surface, and a control of the operating device is arranged on the first mounting surface. Since the first mounting surface is flat, it is particularly suitable for arranging the control. In addition, a flat mounting surface can be easily realized by extrusion. Preferably, the control is designed for actuating an electric motor.

[0014] According to a preferred embodiment, the peripheral wall has a flat second mounting surface, and the electric motor is arranged on the second mounting surface. Since the second mounting surface is flat, it is particularly suitable for arranging the electric motor. In addition, a flat mounting surface can be easily achieved by extrusion.

[0015] Preferably, the peripheral wall has at least one penetration. Preferably, the penetration is formed by subsequent processing of the extruded profile. For example, the penetration is milled into the peripheral wall. In this case, the penetration of the peripheral wall can fulfill various tasks in the operating device. Preferably, the peripheral wall has a penetration for a sensor to be inserted therein, which is configured to monitor the displacement position of the threaded spindle and the pressure transmitter. Alternatively or additionally, the peripheral wall preferably has at least one penetration, through which a drive shaft of the transmission device is rotatably supported. Alternatively or additionally, the peripheral wall preferably has at least one penetration, through which at least one electrically conductive motor phase feed line protrudes.

[0016] The method according to the invention with the features of claim 13 is characterized in that the housing together with the counter-rotation stop is produced by extrusion. This also results in the advantages already mentioned. Further preferred features and feature combinations are derived from the above and the claims. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] Figure 2 shows a cross-sectional view of the operating device,

[0020] Figure 3 shows the housing of the operating device,

[0022] Figure 5 A method of manufacturing a manipulation device is shown. DETAILED DESCRIPTION

[0023] Figure 1 A perspective view of an actuating device 1 for a brake system 2 (not shown in detail) of a motor vehicle is shown. The actuating device 1 has a housing 3. The housing 3 is tubular and has a circumferential peripheral wall 4 which surrounds a housing interior 5 of the housing 3. A disk-shaped housing part 7 is arranged on the end face 6 of the housing 3. In the present case, the housing part 7 is fastened to the housing 3 by a plurality of fastening elements 8. The housing part 7 has a plurality of fastening structures 9 which serve to fasten the actuating device 1 to the body of the motor vehicle.

[0024] The operating device 1 also has a drive unit 10 arranged on the housing 3. The drive unit 10 has an electric motor 12, which is arranged in an electric motor housing 11 and thus Figure 1 The actuating device 1 also has a control unit 13. The control unit 13 is arranged on the housing 3, on the side of the housing 3 facing away from the drive unit 10. The control unit 13 is designed to control the electric motor 12. A brake master cylinder 14 is arranged at the other end side of the housing 3 facing away from the end side 6, in which two hydraulic pistons 15 are movably supported. If the actuating device 1 is installed in the brake system 2 as required, the brake master cylinder 14 is connected to the slave cylinder of the friction brake device of the brake system 2 in terms of fluid technology.

[0025] Figure 2The longitudinal section of the operating device 1 is shown. The operating device 1 has a transmission 16. The transmission 16 is operatively connected to the electric motor 12 so that the transmission 16 can be driven by the electric motor 12. The transmission 16 has a threaded spindle 17 that is movably supported. The threaded spindle 17 extends through a penetration 18 of the housing part 7 into the housing interior 5 of the housing 3 and is therefore partially arranged in the housing interior 5 of the housing 3. The threaded spindle 17 can be moved along the movement axis in a first direction 19 and a second direction 20 opposite to the first direction 19. The directions 19 and 20 are oriented perpendicular to the cross section of the housing 3. The threaded spindle 17 is part of a spindle drive 21 of the transmission 16. The spindle drive 21 has a rotatably supported spindle nut 22 in addition to the threaded spindle 17. The spindle nut 22 can rotate along a first rotation direction 42 and a second rotation direction 43 opposite to the first rotation direction 42. The inner toothing of the spindle nut 22 meshes with the outer toothing of the threaded spindle 17. In order to ensure that the threaded spindle 17 moves when the spindle nut 22 rotates and does not rotate with the spindle nut 22, the threaded spindle 17 is provided with an anti-rotation portion 23. For this purpose, an anti-rotation element 24 is provided, which is fixed to the threaded spindle 17, in the present case at the end of the threaded spindle 17 facing the brake master cylinder 14. According to another embodiment, the anti-rotation element 24 is constructed integrally with the threaded spindle 17. The anti-rotation element 24 cooperates with the housing 3 to form the anti-rotation portion 23, which will be explained in more detail below. In the present case, a pot-shaped push piece 25 is fixed to the anti-rotation element 24.

[0026] The actuating device 1 further comprises a pressure transmitter 26 which is supported so as to be movable relative to the threaded spindle 17, wherein the pressure transmitter 26 also projects through the penetration 18 into the housing interior 5 and is therefore arranged partially in the housing interior 5 of the housing 3. The pressure transmitter 26 can be moved in a first direction 19 and in a second direction 20. In the present case, the pressure transmitter 26 is supported in a penetration 27 of the threaded spindle 17. According to Figure 2 In the embodiment shown, the pressure transmitter 26 is constructed in multiple parts. For this purpose, the pressure transmitter 26 has a rod-shaped section 28 arranged in the penetration 27. The pressure transmitter 26 also has a pressure cap 29, which is arranged at the end of the pressure transmitter 26 facing the brake master cylinder 14. The pressure cap 29 is fixed to the rod-shaped section 28, in the present case by crimping. The end of the pressure transmitter 26 facing away from the brake master cylinder 14 is connected to the input rod 30, so that the pressure transmitter 26 can be moved by the input rod 30. In the present case, the pressure transmitter 26 is connected to the input rod 30 via a ball joint 31. The end of the input rod 30 facing away from the pressure transmitter 26 is fixed to the brake pedal (not shown).

[0027] The master brake cylinder 14 can be actuated by moving the threaded spindle 17 or by moving the pressure transmitter 26. Actuation of the master brake cylinder 14 is understood to mean moving the hydraulic piston 15 in the first direction 19. If the actuating device 1 is installed in the brake system 2 as intended, hydraulic fluid is thereby moved from the master brake cylinder 14 to the slave cylinder of the friction brake device, so that the friction brake device generates a friction braking torque. In the present case, the threaded spindle 17 and the pressure transmitter 26 are operatively connected or operatively connectable to the hydraulic piston 15 via a coupling element 32. The coupling element 32 has an elastically deformable coupling disk 33 and a rigid push rod 34. If the master brake cylinder 14 is actuated by the electric motor 12, the electric motor 12 acts on the hydraulic piston 15 by means of the threaded spindle 17, the anti-rotation element 24, the push piece 25 and the coupling element 32. If the master brake cylinder 14 is actuated by actuating the brake pedal, the brake pedal acts on the hydraulic piston 15 by means of the input rod 30, the pressure transmitter 26 and the coupling element 32.

[0028] According to the following Figure 3 and Figure 4 The structure of the housing 3 is explained in more detail. Figure 3 A perspective view of the housing 3 is shown. Figure 4 A representation of a housing 3 is shown, wherein the viewing direction coincides with the first direction 19. The housing 3 is an extruded profile 3. This means that the housing 3 is produced by extrusion. Without taking into account any subsequent processing of the component, a component produced by extrusion has the same cross section at every point in its longitudinal extension. In the present case, the housing 3 or the extruded profile 3 is made of aluminum. As can be seen from the figure, the housing interior 5 has a circular cross section in the present case.

[0029] As mentioned above, the anti-rotation element 24 cooperates with the housing 3 to form the anti-rotation portion 23. For this purpose, the housing 3 has a plurality of grooves 35, which extend through the peripheral wall 4 of the housing 3 in the housing interior 5. In the present case, two grooves 35 are provided which are diametrically opposite to each other. The grooves 35 are oriented perpendicularly to the cross section of the housing 3 and thus extend in the axial direction relative to the displacement axis of the threaded screw 17. The grooves 35 are respectively formed by a bottom 36, a first corresponding rotation stop 37 and a second corresponding rotation stop 38, wherein the corresponding rotation stops 37, 38 are opposite to each other. The first corresponding rotation stop 37 is oriented against the first rotation direction 42 of the screw nut 22. The second corresponding rotation stop 38 is oriented against the second rotation direction 43 of the screw nut 22. In the present case, the corresponding rotation stops 37, 38 are oriented perpendicularly to the bottom 36. Alternatively, the corresponding rotation stops 37, 38 are oriented obliquely to the bottom 36. For example, the angle between the bottom and the corresponding rotation stops 37, 38 is 60° respectively. The groove 35 is an extruded structure 35 of the extruded profile 3. This means that the groove 35 is made by extrusion. Therefore, the groove 35 can already be identified in the opening of the extrusion tool used to produce the extruded profile 3. The anti-rotation element 24 has a number of radial projections 39 corresponding to the number of grooves 35. Each radial projection 39 radially engages in each different groove 35 to form an anti-rotation portion 23. The radial projections 39 each have a first rotation stop 40 and a second rotation stop 41. The first rotation stop 40 is here opposite to the first corresponding rotation stop 37 of the groove 35. The second rotation stop 41 is opposite to the second corresponding rotation stop 38 of the groove 35.

[0030] If the anti-rotation element 24 and thus the threaded spindle 17 are subjected to a torque acting in a first rotational direction 42 applied by the spindle nut 22, the first rotation stop 40 of the radial projection 39 comes into contact with the first corresponding rotation stop 37 of the groove 35. As a result, the anti-rotation element 24 and thus the threaded spindle 17 are prevented from rotating in the first rotational direction 42. If the anti-rotation element 24 and thus the threaded spindle 17 are subjected to a torque acting in a second rotational direction 43 applied by the spindle nut 22, the second rotation stop 41 of the radial projection 39 comes into contact with the second corresponding rotation stop 38 of the groove 35. As a result, the anti-rotation element 24 and thus the threaded spindle 17 are prevented from rotating in the second rotational direction 43. Therefore, the rotation stops 40, 41 of the anti-rotation element 24 cooperate with the corresponding rotation stops 37, 38 of the extruded profile 3 to form the anti-rotation portion 23.

[0031] According to the embodiment shown in the figures, the radial projections 39 each have a sliding pad 44 made of plastic, wherein the sliding pad 44 forms the rotation stops 40, 41. The sliding pad 44 made of plastic ensures low-friction guidance of the anti-rotation element 24 in the groove 35. According to another embodiment, the groove 35 has a sliding coating at least in the region of the corresponding rotation stops 37, 38. The provision of the sliding coating can also ensure low-friction guidance of the anti-rotation element 24 in the groove 35. If a sliding coating is provided, the sliding pad 44 is particularly omitted.

[0032] As can be seen from the figure, the extruded profile 3 or the housing 3 also has several structures that are not produced by extrusion but by subsequent processing of the extruded profile 3. For example, the housing 3 has a housing step 45 milled out in the peripheral wall 4. In addition, the peripheral wall 5 has a plurality of penetrations 46, 47, 48, which are configured in the region of the first mounting surface 49 of the peripheral wall 4. In the operating device 1 installed as required, the controller 13 is arranged on the first mounting surface 49. The first penetration 46 of the penetrations 46, 47, 48 is of rectangular construction. If the operating device 1 is installed as required, a sensor is arranged in the first penetration 46, which is configured to monitor the displacement position of the threaded screw 17 and the pressure transmitter 26. The second penetration 47 of the penetrations 46, 47, 48 is of circular construction. If the operating device 1 is installed as required, the transmission shaft 50 of the transmission 17, which is configured as a worm shaft 50 in the present case, extends from the housing interior 6 into the penetration 47 or passes through the penetration 47. In particular, the drive shaft 50 is rotatably supported by the bearing surface 51 that delimits the second penetration 47. For example, a rotary bearing is provided, which acts between the drive shaft 50 and the bearing surface 51. The third penetration 48 of the penetrations 46, 47, 48 is of circular design. If the operating device 1 is installed as intended, a plurality of electrically conductive motor phase feed lines 52 extend through the third penetration 48 into the housing interior 5. Figure 2 It can be seen that the extruded profile 3 or the housing 3 also has a fourth penetration 53 and a fifth penetration 54. The penetrations 53 and 54 are constructed in the region of the second mounting surface 55 of the peripheral wall 4. In the operating device 1 installed as specified, the electric motor 12 or the drive unit 10 is arranged on the second mounting surface 55. The fourth penetration 53 is aligned with the second penetration 47. The drive shaft 50 extends from the housing interior 5 into the motor housing 11 through the fourth penetration 53. In the present case, the drive shaft 50 passes through the housing 3. The fifth penetration 54 is aligned with the third penetration 48. The motor phase feed line 52 extends into the motor housing 11 through the fifth penetration 54. Therefore, the motor phase feed line 52 also passes through the housing 3. The motor phase feed line 52 is electrically connected to the motor winding of the electric motor 12 on the one hand and to the controller 13 on the other hand.

[0033] Figure 5A method for producing the actuation device 1 is shown with reference to a flow chart.

[0034] In a first step S1, the housing 3 is manufactured. Here, the housing 3 is manufactured together with the corresponding rotation stops 37, 38 by extrusion. As mentioned above, the housing 3 is thus obtained as an extruded profile 3. The corresponding rotation stops 37, 38 are formed by the extruded structure 35 of the extruded profile 3, in the present case by the groove 35. In a second step S2, the extruded profile 3 is subsequently processed. For example, structures 45, 46, 47, 48, 53, 54 are milled into the extruded profile 3. In a third step S3, a transmission 16 having a movable threaded spindle 17 is provided. In a fourth step S4, the anti-rotation element 24 is connected to the threaded spindle 17 in a non-rotatable manner. According to another embodiment, the anti-rotation element 24 is made integrally with the threaded spindle 17. The threaded spindle 17 is then installed in the transmission 16 together with the anti-rotation element 24. In a fifth step S5, the transmission 16 is arranged such that the threaded spindle 17 is at least partially arranged in the housing 3 and the rotation stops 40, 41 of the anti-rotation element 24 cooperate with the corresponding rotation stops 37, 38 of the extruded profile 3 to form the anti-rotation portion 23. In a sixth step S6, the electric motor 12 is operatively connected to the transmission 16 so that the transmission 16 can be driven by the electric motor 12.
