Description

Technical Field

[0001] The present invention relates to an electromechanical brake booster for a vehicle brake system, a brake system for a vehicle, and a manufacturing method of an electromechanical brake booster for a vehicle brake system. Background Art

[0002] From the prior art, for example, patent document DE 10 2018 211 549 A1, electromechanical brake boosters are known, which have an electric motor, a transmission and a linearly adjustable piston part, which can be adjusted by means of the motor force of the electric motor transmitted by the transmission. Such electromechanical brake boosters usually also include a transmission housing component of the transmission and at least one tie rod, by means of which the linearly adjustable piston part is guided. Summary of the invention

[0003] The invention provides an electromechanical brake booster for a vehicle brake system having the features of claim 1 , a brake system for a vehicle having the features of claim 9 , and a method for producing an electromechanical brake booster for a vehicle brake system having the features of claim 10 .

[0004] The invention provides an electromechanical brake booster in which, due to the intermediate plate, it is no longer necessary to fix at least one tie rod to the housing bottom of a transmission housing component as is conventionally the case. By introducing the intermediate plate into the electromechanical brake booster according to the invention, the respective position of the at least one tie rod is decoupled from the vehicle wall to which the electromechanical brake booster is fixed by means of at least one screw arranged at the housing bottom of the transmission housing component. By the decoupling of the respective position of the at least one tie rod from the vehicle wall achieved by means of the invention, the position of the electromechanical brake booster according to the invention can be selected with (almost) 360° orientation freedom depending on the availability of installation space for arranging the electromechanical brake booster at the vehicle wall. As will become clearer from the following description, by introducing the intermediate plate into the electromechanical brake booster according to the invention, the component differences of the transmission housing component thereof required for equipping a large number of different vehicle types / motor vehicle types with the electromechanical brake booster are greatly reduced. Furthermore, if the electromechanical brake booster according to the invention is equipped with exactly two tie rods fixed to the intermediate plate, the two tie rods can be arranged symmetrically with respect to the electric motor.

[0005] In an advantageous embodiment of the electromechanical brake booster, at least a portion of the intermediate plate forms an electric motor bearing cap of the electric motor. The intermediate plate can thus also be used to integrate the function of a motor bearing cap. With this multifunctionality of the intermediate plate, the embodiments of the electromechanical brake booster described here do not need to be equipped with an “additional motor bearing cap”.

[0006] For example, the intermediate plate can be fastened to the transmission housing component by means of at least one rivet connection, at least one screw connection, at least one weld connection and / or at least one snap connection. For fastening the intermediate plate to the transmission housing component, a variety of fastening techniques that are easy to implement and cost-effective can be used.

[0007] Preferably, at least one threaded element is fastened to the side of the housing bottom of the transmission housing component facing away from the intermediate plate, by means of which the electromechanical brake booster is fastened or can be fastened to the vehicle wall. Since the electromechanical brake booster is additionally equipped with its intermediate plate, the respective position of the at least one tie rod is decoupled from the at least one fastening opening of the at least one threaded element punched through the housing bottom, so that a stamping press that is conventionally adapted to the respective desired position of the at least one tie rod for forming the at least one fastening opening of the at least one threaded element is not required. This reduces the manufacturing costs of the transmission housing component with the at least one threaded element and saves the downtimes that are conventionally present during its production.

[0008] In a further advantageous embodiment of the electromechanical brake booster, a first tie rod and a second tie rod are fastened to the intermediate plate as the at least one tie rod, wherein the first tie rod and the second tie rod extend parallel to one another at a maximum distance of less than or equal to 80 mm. Due to the fastening of the two tie rods to the transmission housing component in the manner according to the invention, the tie rods can be arranged closer to one another. Thus, equipping the electromechanical brake booster with its intermediate plate can be used to save installation space.

[0009] If the end of the at least one tie rod facing away from the intermediate plate is fastened to a flange of the master brake cylinder, the flange of the master brake cylinder can have a maximum diameter of less than or equal to 80 mm in a spatial direction oriented perpendicularly to the at least one tie rod. This can be used to save material on the master brake cylinder housing of the master brake cylinder which is designed with a flange.

[0010] Preferably, a motor housing which at least partially surrounds the electric motor is fixed on the intermediate plate. Therefore, the intermediate plate can also be used to fix the motor housing.

[0011] In a further advantageous embodiment of the electromechanical brake booster, a covering at least partially surrounding the at least one linearly adjustable piston element and the at least one tie rod is fastened to the intermediate plate, wherein the covering has a maximum diameter of less than or equal to 100 mm in a spatial direction oriented perpendicularly to the at least one tie rod. Since the electromechanical brake booster described here is advantageously equipped with its intermediate plate, the distances between a plurality of tie rods are smaller and thus a covering having a reduced diameter compared to the prior art can be used, so that installation space can be saved in the embodiment of the electromechanical brake booster described here.

[0012] The advantages described above are also guaranteed for a brake system for a vehicle having such an electromechanical brake booster. The brake system may be, for example, a brake-by-wire system or a servo brake system.

[0013] Furthermore, carrying out a corresponding production method for an electromechanical brake booster for a vehicle brake system also provides the above-mentioned advantages. It is expressly pointed out that the production method can be improved according to the above-mentioned embodiments of the electromechanical brake booster. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The following is an explanation of the other features and advantages of the present invention with reference to the accompanying drawings.

[0015] Figure 1a to Figure 1d A schematic diagram of a first embodiment of an electromechanical brake booster is shown;

[0016] Figure 2a and Figure 2b A schematic diagram showing a second embodiment of an electromechanical brake booster; and

[0017] Figure 3 A flow chart is shown for explaining an embodiment of a method for producing an electromechanical brake booster of a vehicle brake system. DETAILED DESCRIPTION

[0018] Figure 1a to Figure 1d A schematic diagram of a first specific embodiment of an electromechanical brake booster is shown.

[0019] Figure 1a to Figure 1dThe schematically shown electromechanical brake booster can be used at the brake system of a vehicle / motor vehicle. The brake system can be, for example, a servo brake system, in which a brake operating element (not shown), such as a brake pedal, is mechanically connected to the electromechanical brake booster, so that the driver's braking force applied to the brake operating element can be "introduced" into the brake master cylinder 10, so that a brake pressure can be built up in the brake master cylinder 10 by means of the driver's braking force. In this case, the electric motor 12 of the electromechanical brake booster can be used to participate in increasing the brake pressure built up in the brake master cylinder 10 by means of the driver's braking force by means of its motor force, thereby supporting the driver in terms of force when braking a vehicle / motor vehicle equipped with a servo brake system. Alternatively, the brake system can also be a wire brake system, in which the driver only applies his driver's braking force to the simulator, and the brake pressure in the brake master cylinder 10 is built up only by means of the motor force of the electric motor 12 of the electromechanical brake booster. The basic type of electromechanical brake booster described here can be conveniently optionally adapted to a servo brake system or a wire brake system by only slightly modifying a few components of the electromechanical brake booster. The overall structure of the electromechanical brake booster described below as well as its production process and the assembly process carried out for assembling the electromechanical brake booster on a vehicle / motor vehicle are optionally (almost) unaffected by the subsequent use of the electromechanical brake booster for a servo brake system or a brake-by-wire system.

[0020] The master brake cylinder 10 may alternatively be understood as a master brake cylinder 10 of an electromechanical brake booster or a master brake cylinder 10 that is fixed to an electromechanical brake booster as a component that is manufactured separately from the electromechanical brake booster. It should also be noted that the usability of the electromechanical brake booster is not limited to any specific vehicle type / motor vehicle type of vehicle / motor vehicle that is subsequently equipped with the electromechanical brake booster.

[0021] The electromechanical brake booster has at least one linearly adjustable piston component 14, such as a valve body, in addition to its electric motor 12. In addition, the electromechanical brake booster has a transmission device 16, via which the electric motor 12 is connected to the at least one linearly adjustable piston component 14, so that when the electric motor 12 is running, the motor force of the electric motor 12 is transmitted / can be transmitted to the at least one linearly adjustable piston component 14 via the transmission device 16. The piston component 14 can be linearly adjusted in the direction of the brake master cylinder 10 in particular by means of the transmitted motor force of the electric motor 12, so that a brake pressure can be built up in the brake master cylinder 10 by means of the linearly adjustable piston component 14.

[0022] from Figure 1a It can be seen that the transmission housing component 18 at least partially surrounds the transmission 16 . Figure 1aAlso shown is at least one tie rod 20, to which the at least one linearly adjustable piston part 14 is connected, so that the piston part 14 linearly adjusted by means of the transmitted motor force is guided by means of the at least one tie rod 20. The at least one tie rod 20 can also be understood as a traction anchor. Figure 1a to Figure 1d The electromechanical brake booster also has an intermediate plate 22, to which the at least one tie rod 20 is attached. In addition, the intermediate plate 22 is attached to the transmission housing component 18. Therefore, there is a mechanical contact between the at least one tie rod 20 and the intermediate plate 22 and between the intermediate plate 22 and the transmission housing component 18. However, it should be pointed out that the intermediate plate 22 is understood to be a component manufactured separately from the transmission housing component 18.

[0023] By fixing the at least one tie rod 20 to the intermediate plate 22, it is no longer necessary to fix the at least one tie rod 20 directly to the housing bottom of the transmission housing component 18, that is, to fix the at least one tie rod 20 to be in mechanical contact with the housing bottom of the transmission housing component 18 as in the conventional method. As a result, the transmission housing component can be manufactured without punching out at least one tie rod opening to fix the at least one tie rod 20 to the housing bottom of the transmission housing component 18. Although the prior art still requires punching out at least one tie rod opening on the transmission housing component 18 by means of a stamping press, Figure 1a to Figure 1dThe electromechanical brake booster does not need to be installed. This is advantageous because when the electromechanical brake booster is assembled on different vehicle types, the transmission housing component 18 is arranged in different orientations according to the available installation space. (The orientation selected for the transmission housing component 18 when assembling the electromechanical brake booster is usually predetermined by the availability of sufficient installation space for the electric motor 12.) Since it is no longer necessary to punch out at least one tie rod opening as conventionally to fix the at least one tie rod 20 to the transmission housing component 18, it is no longer necessary to modify the stamping press used for this purpose according to the type of vehicle to be equipped with the electromechanical brake booster later, and the downtime required for placing the tool in the manufacturing for this purpose is saved. In addition, the component differences required in the prior art of the transmission housing component 18, such as multiple part families with different geometric differences, are also eliminated. The elimination of the traditionally required "mirror" / "non-mirror" part differences also helps to reduce the component differences of the transmission housing component 18 of the electromechanical brake booster described here. The reduction of component differences also makes it possible to reduce process differences on the production line. By eliminating the tool downtime that would occur in the traditional way, the production line can also be used more efficiently. Since the number of tool changes on the production line is also significantly reduced, the tools can also be designed to be less complex and therefore cheaper. The costs that would occur in the traditional way are also eliminated for variant management. In addition, by reducing the component differences, the complexity of the production line can be reduced, which has a positive impact on its service life and the initial investment in the production line. The advantages described here all contribute to cost savings when manufacturing the transmission housing component 18, compared to which the "additional cost" of the intermediate plate 22 is negligible.

[0024] The intermediate plate 22 can be fixed to the transmission housing component 18, for example, by means of at least one rivet connection 24, at least one threaded connection, at least one welded connection and / or at least one snap-in connection. Thus, a variety of easily formable and secure connection types can be used to fix the intermediate plate 22 to the transmission housing component 18. The intermediate plate 22 can have a flat / planar shape. However, it should be noted that Figure 1aThe shape of the intermediate plate 22 shown as a flat / planar plate is to be interpreted only as an example. The surface area of ​​the intermediate plate 22 can be so dimensioned that the intermediate plate 22 fixed to the transmission housing component 18 completely covers the recess / receiving opening of the transmission 16 formed in the transmission housing component 18. For example, the intermediate plate 22 can also be formed with a central opening 22a, so that the motor force of the electric motor 12 can be transmitted to the at least one linearly adjustable piston component 14 via at least one component of the transmission 16 protruding through the central opening 22a of the intermediate plate 22. Optionally, the driver's braking force can also be transmitted in the direction of the master brake cylinder 10 via a force transmission component (for example an input rod) protruding through the central opening 22a of the intermediate plate 22.

[0025] Figure 1b Shows Figure 1a 2. The electromechanical brake booster after the components shown separately in FIG. 2 have been assembled. It can be seen that the electromechanical brake booster has at least one threaded member 26, which is fixed to the side of the housing bottom of the transmission housing component 18 facing away from the intermediate plate 22. The at least one threaded member 26 can be, for example, a stud. The at least one threaded member 26 can be used to fix the electromechanical brake booster to a vehicle wall (not shown) of the vehicle / motor vehicle during the assembly of the electromechanical brake booster to the vehicle / motor vehicle equipped with the electromechanical brake booster. The corresponding position of the at least one fixing opening of the at least one threaded member 26, which is punched through the housing bottom of the transmission housing component 18, can be selected relatively freely.

[0026] from Figure 1b It can also be seen that a motor housing 28 at least partially surrounding the electric motor 12 can be fastened to the intermediate plate 22. The motor housing 28 can be fastened to the intermediate plate 18, preferably to the side of the intermediate plate 18 facing away from the transmission housing component 18, for example, by means of at least one rivet connection 29, at least one screw connection, at least one weld connection and / or at least one snap connection.

[0027] Figure 1c Shows Figure 1b Cross section of a part of an electromechanical brake booster. Figure 1c It can be seen that at least a portion of the intermediate plate 22 can form a motor bearing cap / A bearing cap of the electric motor 12. Thus, the function of the motor bearing cap / A bearing cap, which is designed as a separate component, can be assumed by the intermediate plate 22. Thus, by using the intermediate plate 22, the motor bearing cap / A bearing cap, which is designed as a separate component in a conventional manner, can be omitted (without replacement). Figure 1cAs shown, another opening 22b through the intermediate plate 22 may be constructed at the intermediate plate 22, through which the planetary carrier 30 protrudes. A planetary gear transmission device (Planetary Gear) 32 arranged in the motor housing 28 may be arranged at the planetary carrier 30, and a drive gear (Drive Gear) 34 of the planetary carrier 30 is located on the side of the intermediate plate 22 facing away from the planetary gear transmission device 32. The drive gear 34 can also be arranged at the housing bottom of the transmission housing component 18 by means of a bearing support (Bearing Carrier) 36. However, Figure 1c The components 30 to 36 illustrated in the drawings should be interpreted as exemplary only.

[0028] Figure 1a to Figure 1d The schematically shown electromechanical brake booster has exactly two tie rods 20 fixed to the intermediate plate 22 as at least one tie rod 20 of the electric brake booster. Since the two tie rods 20 are fixed to the intermediate plate 22, it is not necessary to maintain a minimum distance of at least 100 mm (millimeter) between the two tie rods 20, as is conventionally required for tie rods fixed to the housing bottom of the transmission housing component 18. Therefore, the maximum distance between the two tie rods 20 can be less than 100 mm (millimeter). For example, the two tie rods 20 of the electromechanical brake booster described here can extend parallel to each other at a maximum distance of less than or equal to 80 mm (millimeter), in particular a maximum distance of less than or equal to 75 mm (millimeter), in particular a maximum distance of less than or equal to 70 mm (millimeter).

[0029] As is apparent from the following description, the reduction in the maximum distance between the two tie rods 20 can be used to reduce the installation space requirement of an electromechanical brake booster designed in this way:

[0030] The reduction of the maximum distance between the two tie rods 20 of the electromechanical brake booster can be used, for example, to reduce the size of the master cylinder housing 38 of the master cylinder 10. In particular, the flange 38a of the master cylinder housing 38 of the master cylinder 10, to which the ends of the tie rods 20 facing away from the intermediate plate 22 are respectively fixed, can be designed to be smaller. For example, the master cylinder 10 of the electromechanical brake booster can be designed with a flange 38a of its master cylinder housing 38, which has a maximum diameter of less than or equal to 80 mm (millimeter), for example, a maximum diameter of less than or equal to 75 mm (millimeter), in particular, a maximum diameter of less than or equal to 70 mm (millimeter) in a spatial direction oriented perpendicularly to the tie rods 20. The material saving associated with this at the master cylinder housing 38 reduces its manufacturing costs and makes it easier to assemble the master cylinder 10. Since the maximum extension of the flange 38a of the brake master cylinder housing 38 perpendicular to the tie rods 20 is (essentially) predetermined by the maximum distance between the tie rods 20, the reduction in the maximum diameter of the flange 38a of the brake master cylinder housing 38 achieved by means of the advantageous reduction in the maximum distance between the tie rods 20 does not bring any disadvantages.

[0031] Figure 1a to Figure 1d Also shown is a covering 40, which at least partially surrounds at least one linearly adjustable piston component 14 and the tie rod 20 and is fixed to the intermediate plate 22. Due to the reduction in the maximum distance between the tie rods 20, the covering 40 can also be constructed to be smaller. In particular, the covering 40 can have a maximum diameter of less than or equal to 100 mm (millimeter), for example, a maximum diameter of less than or equal to 90 mm (millimeter), in particular a maximum diameter of less than or equal to 80 mm (millimeter) in a spatial direction oriented perpendicularly to the tie rod 20. Therefore, for the covering 40, the unused dead volume (Tot volume) that often occurs in the conventional manner in the housing 42 that at least partially surrounds at least one linearly adjustable piston component 14 and the tie rod 20 is eliminated. Alternatively, for the electromechanical brake booster described here, the design of the covering 40 can be optimized so that there is (almost) no unused dead volume in the covering 40. This allows for further saving of installation space for the electromechanical brake booster. At the same time, less material can be used for the cover member 40 , thereby reducing its manufacturing cost. Optionally, the cover member 40 may be configured with a seal 40 a that seals the gap existing between the cover member 40 and the intermediate plate 22 in a liquid-tight manner.

[0032] For comparison, Figure 1d The housing 42 of a conventional electromechanical brake booster is shown, which at least partially surrounds at least one linearly adjustable piston component and a tie rod of the electromechanical brake booster. The housing 42 of the conventional electromechanical brake booster is projected onto Figure 1a to Figure 1d The electromechanical brake booster is coated with a cover 40. Figure 1a to Figure 1d The installation space requirement of the electromechanical brake booster is also significantly reduced by the advantageous reduction in the size of its cover 40. In addition, the reduction in the size of the cover 40 makes it easier to arrange the control electronics 43 on the side of the motor housing 28 facing away from the intermediate plate 22.

[0033] Figure 2a and Figure 2b A schematic diagram of a second specific embodiment of an electromechanical brake booster is shown.

[0034] exist Figure 2a and Figure 2b In the electromechanical brake booster of , the intermediate plate 44 is designed as a U-shaped profile (carrier) 44. The U-shaped profile 44 is smaller and more resistant to bending than the intermediate plate 22 of the previously described embodiment. The recess / receiving opening of the transmission 16 formed in the transmission housing component 18 is only partially covered by the U-shaped profile 44 fixed to the transmission housing component 18. A central opening 44a can also be formed in the U-shaped profile 44, so that the motor force of the electric motor 12 can be transmitted to the at least one linearly adjustable piston component 14 via at least one component of the transmission 16 protruding through the central opening 44a, and the driver's braking force can also be transmitted in the direction of the brake master cylinder 10 via the force transmission component protruding through the central opening 44a.

[0035] The (not shown) covering 40 is preferably designed such that the covering 40 projects beyond the U-shaped profile 44, ie the U-shaped profile 44 is located within the volume defined by the covering 40. Thus, no sealing between the covering 40 and the U-shaped profile 44 is required.

[0036] about Figure 2a and Figure 2b For further characteristics and features of the electromechanical brake booster and its advantages, please refer to Figure 1a to Figure 1d An explanation of the implementation method.

[0037] Figure 3 A flow chart is shown for explaining one specific embodiment of a method for producing an electromechanical brake booster for a vehicle brake system.

[0038] All of the above-mentioned electromechanical brake boosters can be manufactured by executing the manufacturing method described below. However, it should be noted that the feasibility of the manufacturing method is not limited to manufacturing the above-mentioned electromechanical brake boosters.

[0039] In method step S1 of the manufacturing method, an electric motor of an electromechanical brake booster to be completed is connected to at least one linearly adjustable piston component of the electromechanical brake booster to be completed via a transmission device, so that during the subsequent operation of the electric motor, the motor force of the electric motor is transmitted to the at least one linearly adjustable piston component via the transmission device. In method step S2, the transmission device is at least partially surrounded by a transmission device housing component. In addition, in method step S3, the at least one linearly adjustable piston component is connected to at least one tie rod, so that the piston component that is linearly adjusted at least by means of the transmitted motor force is guided by means of the tie rod.

[0040] The manufacturing method further comprises method steps S4 and S5. In method step S4, the at least one tie rod is fixed to an intermediate plate which is manufactured as a component independent of the transmission housing component. Furthermore, in method step S5, the intermediate plate is fixed to the transmission housing component. By carrying out method steps S4 and S5, the advantages already explained above are achieved. Method steps S1 to S5 can be carried out in any order, simultaneously or overlapping in time.
