Description

Technical Field

[0001] The invention relates to a lining carrier plate for a disc brake of a motor vehicle. The invention also relates to a method for producing a lining carrier plate. Background Art

[0002] Pad carrier plates for disc brakes for motor vehicles are known in various ways. In the disc brake device, the pad carrier plate is guided and supported in the shaft of the brake caliper or brake carrier. The pad carrier plate is designed to receive the brake pressure transmitted by the brake cylinder so as to further transmit the brake pressure to the brake disc. In order to reliably hold the pad carrier plate in the shaft of the brake caliper or brake carrier, a pressure spring is provided, which usually acts on the upper side of the pad carrier plate and is preloaded radially and tangentially toward the pad carrier plate by means of a pressure device. For example, a pad carrier plate with the pressure spring is proposed in DE 10 2013 008 155 A1. A wire spring for a brake pad assembly in a floating caliper brake is known from DE 10 351 477 B4. There, the wire spring is supported by its circular coil in a recess in a lining carrier plate for the brake pad in order to prevent the brake pad from rattling on the guide in the brake pad assembly. Summary of the invention

[0003] The object of the present invention is to provide a lining carrier plate in which an exchangeable arrangement of the spring elements is possible, wherein the logistical expenditure for stocking the required components is minimized and the mounting of the spring elements on the lining carrier plate is also simplified. In addition, the object of the present invention is to provide a method for producing such a lining carrier plate.

[0004] According to the device, this object is achieved by a lining carrier plate having the features of the technical solution of the invention. With regard to the method for producing the lining carrier plate, this object is achieved by a method having the features of the technical solution of the invention. Advantageous embodiments of the invention are realized in the technical solution of the invention.

[0005] The lining carrier plate according to the invention for a disc brake of a motor vehicle, in particular a commercial vehicle, has a front side which is designed to receive a friction lining. The lining carrier plate according to the invention is characterized in that the lining carrier plate has a rear side on which a receiving device is arranged, which is designed to receive a spring element, which consists of a spring base and two spring arms arranged at the ends of the spring base. The spring element can be designed as a wire spring. In this case, the receiving device is designed on the rear side of the lining carrier plate in a materially compatible manner with the lining carrier plate. In particular, protection can also be claimed for the lining carrier plate according to the invention with the spring element.

[0006] It is therefore particularly advantageous in the lining carrier plate according to the invention that the receiving device for receiving the spring element is an integral component of the lining carrier plate and is already produced together with the lining carrier plate when the lining carrier plate is manufactured. As a result, the receiving device is held on the lining carrier plate in a non-lost manner. It is therefore not necessary to stock individual elements, such as screws or retaining clips, so that the receiving device for the spring element can be arranged on the rear side of the lining carrier plate. The logistics costs for purchasing and storing the individual components are thus eliminated. In addition, the processing step of joining the individual components to the lining carrier plate on its rear side is also eliminated. Unlike the lining carrier plate described below, in this lining carrier plate, the receiving device for the spring element can be subsequently mounted on the rear side of the lining carrier plate by means of retaining clips or similar elements to be screwed in, and the processing step of machining the threads for the screws into the rear side of the lining carrier plate is also eliminated. In summary, the manufacturing costs of the lining carrier plate with the receiving device for the spring element can be significantly reduced by the present invention.

[0007] The lining carrier plate according to the invention can thus also minimize the logistical effort and energy expenditure for arranging the receiving device for the spring element on the rear side of the lining carrier plate. As a result, not only the economic balance but also the ecological balance of the lining carrier plate according to the invention is significantly improved compared to the lining carrier plates known from the prior art.

[0008] According to a first advantageous embodiment of the invention, the receiving device has at least one supporting element on the rear side of the lining carrier plate for the spring base and each of the two spring arms. This embodiment of the invention ensures that the spring is securely held in the shaft of the brake caliper or brake carrier during operation of the lining carrier plate in the brake system, wherein the supporting element supports the spring element under load in such a way that the spring element can realize the desired spring function in the brake system, in particular as a pressure spring.

[0009] Alternatively, only one support element for two spring arms and / or spring bases can also be provided. The support element can be designed as a projection with at least one through-opening or recess, similarly a retaining handle or pocket groove. The support element can have two through-openings, in particular holes, for introducing the spring arms.

[0010] The receiving device can have only one supporting element for the spring base and / or only one supporting element for the spring arm. According to an advantageous design, the reduced receiving device has one or more supporting and guiding elements described below for stabilizing the configured spring.

[0011] In an advantageous further development of the invention, it is provided that at least one of the support elements is configured with an undercut relative to the rear side of the lining carrier plate for receiving a spring base or a spring arm of a spring element. The undercut further improves the supporting effect and the non-lost positioning of the spring element inside the receiving device, since the individual elements of the spring element, in particular the spring arm and the spring base, are surrounded on multiple sides by the undercut. The loss-proofness of the spring placed in the receiving device is thus optimized. The undercut can be configured in different ways here. For example, it is conceivable that in a particularly advantageous design the support element has a region arranged perpendicularly to the lining carrier plate, to which an angled, in particular right-angled region of the support element adjoins, the angled, in particular right-angled region being arranged at an angle of less than 90° relative to the rear side of the lining carrier plate, in particular parallel to the rear side of the lining carrier plate. Another possibility for configuring the undercut is that the support element for the spring base or the spring arm is configured such that it has an acute-angled surface relative to the rear side of the lining carrier plate in the region supporting the spring element. The undercut described here is particularly well suited for holding the spring element in a loss-proof manner within a receptacle for the spring element. In principle, the undercut can be designed so that it matches the contour of the spring element. In particular, in the case of a spring element that is circular in cross section, the undercut can have a corresponding arc-shaped support surface for the spring element.

[0012] The following embodiment of the invention is directed to the same direction, namely that the receiving device has a fixing element assigned to the supporting element for the spring base. By means of the fixing element, a region is formed between the fixing element and the supporting element for the spring base, in which the inserted spring element can be received in a loss-proof manner. This is the case in particular when the supporting element of the spring arm has the aforementioned undercut. Thus, the spring element is held in the receiving portion for the spring element on the rear side of the lining carrier plate in a displacement-proof and loss-proof manner.

[0013] According to a further advantageous embodiment of the invention, the receiving device has a common support and guide element for the two spring arms, which is arranged on the central longitudinal axis between the upper side of the lining carrier and the support elements of the two spring arms. The support element is primarily used to support the spring arms on the support element when they are loaded when the lining carrier plate is inserted into the shaft of the brake caliper or the brake carrier. In addition, the support element can be used as a guide element when the spring is inserted into the receiving device on the rear side of the lining carrier plate. That is, the spring can be guided by the support element during insertion in such a way that the common support element of the spring arms is located between the spring arms and the spring element is now moved in such a way that it is guided between the support elements assigned to the respective spring arms. The aforementioned fixing element of the support element assigned to the spring base then serves to fix the spring inside the receiving device in that the spring element with its spring base is pushed over the fixing element. It can be provided here that the fixing element assigned to the supporting element for the spring base is provided with a starting ramp, over which the spring element with its spring base is pushed, whereby the spring base is securely held between the supporting element of the spring base and the fixing element.

[0014] Instead of the aforementioned common support and guide element or in addition thereto, further elements can be provided, which are respectively assigned to individual spring arms. The further support and guide element is preferably arranged between the upper side of the lining carrier and the support element of the two spring arms, not on the central longitudinal axis. The element can be designed, for example, as a projection with a cylindrical or polygonal cross section and optionally also with an undercut. According to a further advantageous design of the invention, the spring arm is provided with a support region at its open end, with which the spring element is supported on the support element of the disc brake system when the lining carrier is mounted in the disc brake system. A contact region for the disc brake system on the spring element is thus achieved, wherein the contact region of the spring element is matched to the disc brake system.

[0015] It is also particularly advantageous that the lining carrier plate according to the invention is designed as a metal casting, preferably as a cast iron part. That is to say, many lining carrier plates currently in use are manufactured as such cast iron parts. Therefore, it is not necessary to provide a completely new manufacturing process for the casting in order to manufacture the lining carrier plate according to the invention. It is sufficient to adjust the casting mold for the lining carrier plate accordingly. Otherwise, the entire manufacturing method can remain unchanged. The use of different casting molds that are replaced with one another during production must be implemented anyway, because different brake systems require different lining carrier plates.

[0016] The method according to the invention for producing the aforementioned lining plate carrier plate, in particular from a metal casting, comprises the following method steps:

[0017] a. providing a liner carrier plate at least divided into two parts of the female mold, the at least two parts of the female mold having a female mold for receiving means,

[0018] b. providing a metal melt, in particular a cast iron melt,

[0019] c. closing the female mold of the liner carrier plate which is divided into at least two parts,

[0020] d. filling the at least two-part female mold of the lining carrier plate with the melt,

[0021] e. causing the melt inside the closed female mold of the liner carrier plate to at least partially harden,

[0022] f. Open the female mold of the liner carrier plate,

[0023] g. Remove the at least partially hardened liner carrier plate.

[0024] The method according to the invention is characterized in that the negative mold of the lining carrier plate has a negative mold for the receiving device. Due to this embodiment of the invention, the receiving device is already produced during the casting of the lining carrier plate as an integrated component of the lining carrier plate, without requiring a subsequent joining process step in order to mount a corresponding receiving device on the rear side of the lining carrier plate.

[0025] In order to ensure that the spring element is securely positioned within the receiving device, it is provided that at least one of the supporting elements for the spring base and the two spring arms is provided with an undercut. The undercut is preferably produced by milling at least one supporting element. The milling can be performed in such a way that the shape of the undercut matches the shape or contour or cross-section of the spring element, thereby achieving a particularly good supporting effect of the spring element within the receiving device when the spring element is loaded during operation.

[0026] According to a further advantageous method step, it can be provided that the fixing element assigned to the spring base and / or the common supporting element for the two spring arms are further processed. In particular, a starting ramp can be processed in the fixing element assigned to the spring base, which facilitates a secure positioning of the spring element within the receiving device when the spring element is inserted into the receiving device.

[0027] In order to finally arrange the lining carrier plate together with the spring element for reliable and correct functioning within the brake system, the spring element is inserted into the receiving device.

[0028] Alternatively, it can also be provided that the lining carrier plate is designed as a steel plate. The lining carrier plate can be punched out of a rolled steel strip, for example. The receiving device can be formed by a progressive transfer method, in particular by a punching method.

[0029] According to an advantageous further development, the receiving device has a pin-shaped projection, also referred to as a pin, on the rear side of the lining carrier plate as a supporting element, in particular for supporting a spring arm. The spring arm preferably rests at least partially on the pin in the assembled position.

[0030] The pins can be designed, for example, in a circular manner, but can also have other shapes. The pins can be designed, for example, in a semicircular manner, wherein the undercuts can each point only toward the center of the lining carrier plate.

[0031] The method according to the invention for producing the aforementioned lining carrier plate with a pin on the rear side from steel comprises that the receiving device of the lining carrier plate is constructed with a pin-shaped projection with an undercut, which projection is constructed as a supporting element and protrudes beyond the rear side of the lining carrier plate by squeezing a part of the lining carrier plate, wherein in a first step the pin-shaped projection is constructed in a forming process, and in a second step the pin-shaped projection is pressed open and formed in a direction opposite to the forming process of the first step, thereby forming the undercut.

[0032] Rolled steel strips can be used for producing the lining carrier plate. The lining carrier plate or the contour of the lining carrier plate can be punched out of the steel strip, for example. BRIEF DESCRIPTION OF THE DRAWINGS

[0050] exist Figure 1 1 shows a lining carrier plate 1 produced according to the method according to the invention in a top view of the rear side. The lining carrier plate 1 has a front side 2, a rear side 3, a lining carrier plate upper side 17, to which a friction lining can be attached, and a lining carrier plate underside 24. Figure 14. The receiving element 4 is composed of a support element 9 for the spring base, two support elements 10 and 11 for the spring arms, a common support element 18 for the spring arms and a fixing element 15 for the spring base. The fixing element 15 also has a starting ramp 23, over which the spring base is pushed when the spring element is inserted, so as to be located between the fixing element 15 and the support element 9.

[0051] The spring element 5 can be designed as a wire spring, which is the case in the exemplary embodiment. In the case of the wire spring 5, the spring base 6 is a substantially semicircular ring. In particular, spring arms 7, 8 extending approximately parallel to each other in the receiving device 4 are connected to the spring base. The semicircular ring and the parallel spring arms form a substantially U-shaped section 35 of the spring element 5 or the wire spring. The free or open ends 19, 20 of the arms 7 and 8 are at least partially angled relative to each other, in particular the free ends 19, 20 extend outwards in the assembled position. In addition, support areas 21 and 22 are arranged on the free ends 19, 20, with which the spring element 5 or the spring arms can be supported in the brake system in the assembled state during operation in the brake system, so as to achieve a spring action. The spring element 5 can have a transition from the U-shaped section 35 of the arms 7, 8 to the angled area approximately in the middle. The lining carrier plate 1 according to the invention can in particular have the spring element 5, in particular the wire spring.

[0052] In this embodiment, the receiving device 4 is designed mirror-symmetrically with respect to the central longitudinal axis 16 of the lining carrier plate 1. In this case, both the common support element 18 for the spring arms and the fastening element 15 and the support element 9 for the spring base are located mirror-symmetrically on the central longitudinal axis 16, while the corresponding mirror-support elements 10 and 11 of the spring arms are spaced symmetrically from the central longitudinal axis 16.

[0053] exist Figure 4 1 shows a detailed view of the receiving device 4 in a perspective view from the upper side 17 of the lining carrier plate. It can be seen here that the support element 9 for the spring base is arranged on the rear side 3 of the lining carrier plate 1 in the region of the lining carrier plate underside 24. Adjacent to the support element 9 for the spring base is a fixing element 15 which is provided with a starting ramp 23 which points away from the support element 9. The spring base of the spring element to be inserted can be pushed over the starting ramp 23 so that the spring base can be reliably positioned between the support element 9 of the spring base and the fixing element 15. The fixing element 15 ensures that the inserted spring element cannot be removed from the receiving device 4 in a simple manner. Furthermore, the support element 9 for the spring base can also be provided with an undercut which is not machined here.

[0054] In addition, according to Figure 4 The two support elements 10 and 11 on the rear side 3 of the lining carrier plate 1 can be clearly seen in the view of FIG. In the exemplary embodiment described, the support elements 10 and 11 each have an undercut 13, 14 in which the spring arms of the spring element lie when the spring element is inserted. The undercuts 13 and 14 ensure that the spring element is captively held in the receiving device 4 in the inserted state in interaction with the fixing element 15 and the support element 9 for the spring base. Finally, in FIG. Figure 3 Also shown in FIG. 1 is a common supporting element 18 of the spring arms of the spring element, which is designed cylindrically in the exemplary embodiment selected here.

[0055] exist Figure 5 , a further detail of the receiving device 4 is shown, this time in a top view of the lining carrier plate underside 24. Here, the front side 2 of the lining carrier plate 1 can now also be seen, on which the friction lining can be mounted.

[0056] In accordance with Figure 5 1 , the undercuts 13 and 14 of the support elements 10 and 11 for the spring arms of the spring elements can be clearly seen in the view of FIG. 1 . The support elements 10 and 11 are designed in this case such that they have webs 25, 26 which stand substantially vertically on the rear side 3 of the lining carrier plate 1 and to which regions 27, 28 which extend substantially parallel to the rear side 3 of the lining carrier plate 1 are connected. The undercuts 13 and 14 are designed in this case such that their shape is adapted to the contour or cross section of the spring arms of the spring elements which are circular in cross section. The undercuts adapted to the shape of the spring arms result in a very good supporting effect of the support elements 10 and 11 and a secure, non-lost arrangement of the spring elements within the receiving device 4.

[0057] exist Figure 2 and 3 4 shows the spring element 5 being introduced into the receiving device 4 of the lining carrier plate 1. The spring element 5, which is produced from a metal part or wire that is circular in cross section, here essentially comprises a rounded spring base 6, to which the parallel-running regions of the spring arms 7 and 8 adjoin. Furthermore, support regions 21 and 22 are arranged at the open ends 19, 20 of the arms 7 and 8, with which the spring element 5 or the spring arms can be supported on the brake device in the assembled state during operation in the brake device, in order to thereby achieve a spring action.

[0058] As by Figure 2 As can be seen, for the initial insertion of the spring element 5 , the spring base 6 is positioned between the common support element 18 and the respective support elements 10 and 11 of the spring arms 7 and 8 , wherein the spring arms 7 and 8 are positioned opposite the common support element 18 .

[0059] The spring element 5 is now subsequently moved in the direction of the support element 9 for the spring base 6. In this case, the spring arms 7 and 8 are positioned between their respective support elements 10 and 11. In order to position the spring element 5 in a loss-proof manner within the receiving device 4, the spring element 5 is now pushed with its spring base 6 over the start ramp 23 of the fixing element 15 until the spring base 6 is located between its support element 9 and the fixing element 15. During the movement of the spring base 6 on the start ramp 23 of the fixing element 15, stresses are generated in the spring element 5, which are relieved again when the spring base 6 is moved over the start ramp 23 and the fixing element 15. In this case, the spring base 6 jumps into the gap between the fixing element 15 and the support element 9 of the spring base 6. The spring base 6 is now thus securely and captively held in the receptacle 4 for the spring element 5 , since the fixing element 15 prevents a return movement of the spring element 5 while the undercuts 13 and 14 of the support elements 10 and 11 of the spring arms 7 and 8 make it impossible for the spring element 5 to pivot out of the receptacle 4 .

[0060] During operation in the brake system, the spring element 5 can now be supported under load with its spring arms 7 and 8 on the common support element 18 , wherein the lining carrier plate 1 is thereby held in its position. The spring element 5 here serves as a pressure spring for the lining carrier plate 1 .

[0061] exist Figures 6 to 8 A second embodiment of a lining carrier plate 1 according to the invention is shown in FIG. Figures 1 to 6 In contrast to the first exemplary embodiment, however, an additional support element 29 or 30 is provided for each of the spring arms 7 and 8, which is arranged above the support and guide element 18 between the support and guide element and the lining carrier top side 17. However, in contrast to the support elements 10 and 11 of the spring arms 7 and 8, the support elements 29 and 30 do not have an undercut. However, further exemplary embodiments are also conceivable in which the support elements 29 and 30 are also provided with an undercut.

[0062] exist Figures 6 to 8 In the exemplary embodiment, the support elements 29 and 30 are substantially aligned with the correspondingly assigned support elements 10 and 11 of the spring arms 7 and 8 with respect to the central longitudinal axis 16 and are designed in a mirror-symmetrical manner with respect to the central longitudinal axis 16. In other exemplary embodiments, it can also be provided that the support elements 29 and 30 have a greater or smaller spacing with respect to the central longitudinal axis 16 than the support elements 10 and 11 and are thus not aligned with them, but always still have a mirror-symmetrical manner with respect to the central longitudinal axis 16.

[0063] Fig. 9A third embodiment of a lining carrier plate 1 according to the invention is shown, which corresponds substantially to Figures 6 to 8 However, in contrast to the second exemplary embodiment, no support element 18 is provided for the spring arms 7 , 8 .

[0064] exist Fig.10 A fourth embodiment of a lining carrier plate 1 according to the invention is shown in FIG. Figures 1 to 5 , wherein, however, likewise no supporting element 18 is provided for the spring arms 7 , 8 .

[0065] according to Figures 11 to 14 A fifth embodiment of a lining carrier plate 1 according to the invention is shown, wherein the lining carrier plate 1, which is essentially made of steel, has in this example a receiving device 4 with four pin-shaped projections 31, which are also referred to as pins, designed as supporting elements. Of course, a different number of pins 31 is also conceivable. The pins 31 are arranged on the rear side 3 of the lining carrier plate 1. The spring arms 7, 8 rest at least partially on the pins 31. As with the Figures 11 to 13 As can be further seen, in this exemplary embodiment, support elements 29 and 30 are also provided for the spring arms 7, 8. Fig.14 The dissection is shown in Fig.11 A cross-sectional view of the center line.

[0066] according to Figures 15 to 17 The sixth embodiment of the invention differs from the fifth embodiment in that the lining carrier plate 1 according to the invention is not provided with lateral support elements 29 and 30 for the spring arms 7, 8. The lining carrier plate 1, which is essentially made of steel, has a plurality of, here four, pins 31, against which each spring arm 7, 8 rests at least partially. Fig.16 The cutting according to the cutting line 36 is shown. Fig.15 A cross-sectional view of the pin 31 in FIG. Fig.17 According to Fig.16 A partial enlarged view of the view.

[0067] As especially according to Fig.17 As can be seen in the enlarged view of , the pin-shaped projection 31 is designed as an extruded part and is therefore designed integrally with the carrier plate 1 .

[0068] To produce the pin-shaped projections or pins 31, a plurality of round pins, for example with a diameter of approximately 6 mm, are first extruded from the front side 2 of the carrier plate 1 by means of a tool with a concavely shaped tip, so that the plurality of pins 31 protrude from the upper surface of the carrier plate on the rear side 3. In general, the ratio of the pin diameter to the carrier plate thickness can be between 1 and 2, ie preferably slightly greater than 1.

[0069] In a second method step, a tool is pressed in the opposite direction onto the protruding pin 31 in order to fold the pin 31 open in a further forming process and form a projection 32 with an undercut 33 from the pin 31. In this case, a tool with a pyramidal tip can be used, which facilitates the folding of the pin 31. A tool with a conical tip can also be used, but a tool with a pyramidal tip is preferred.

[0070] As by Fig.17 As can be seen further, a strong undercut 33 is formed by the calendering projection 32, by which the friction lining can be anchored on the carrier plate 1 in such a way that high shear forces can be absorbed. A circular recess 34, for example with a depth of 2 to 3 mm, remains on the front side 2 of the carrier plate 1, the bottom of which can be convexly curved.

[0071] When the friction lining is pressed onto the carrier plate 1 , the friction material of the friction lining can enter into the undercut 33 and be firmly anchored there.
