Description
[0001] Caliper cover assembly for a brake caliper, brake caliper assembly for a
[0002] Motor vehicle disc brake and commercial vehicle disc brake
[0003] The present invention relates to a saddle cover arrangement according to the preamble of claim 1 for a brake caliper for a motor vehicle disc brake, comprising at least a saddle cover.
[0004] The present invention also relates to a brake caliper assembly - or hereinafter also brake caliper - for a motor vehicle disc brake, in particular for a commercial vehicle disc brake with a brake disc moved about an axis of rotation, in particular for a sliding caliper brake, with a caliper housing with a cavity for receiving a clamping mechanism, and with a caliper cover which covers a brake carrier on the upper side and extends over the brake disc from a clamping side of the brake disc to a reaction side of the brake disc.
[0005] Preferably, the cavity serves to accommodate a clamping mechanism that includes a brake lever pivotable about a lever axis. The caliper housing has a vehicle-side housing wall made of a single piece of bent sheet metal, on the inside of which at least one support element is provided for supporting the brake lever. Preferably, the caliper housing is designed for a retaining bracket that can be reversibly and detachably attached to a bracket on the reaction side of the caliper cover to span the brake disc from the clamping side to the reaction side. Preferably, the caliper cover is made partially or completely of sheet metal.
[0006] From WO2016 / 135316 A1, a brake caliper for a disc brake is known in principle, in which a caliper cover and a caliper housing are assembled from segments, each segment being made of sheet metal. However, caliper housings and caliper covers for motor vehicle disc brakes are generally used for brake calipers in which the caliper housing or caliper covers and / or the brake caliper are cast parts. Those functional elements of the brake caliper and the caliper housing and / or the caliper cover, in particular, that require very precise alignment and surface finishing because they movably mount or hold functionally critical components, are mechanically post-processed in these cast parts to enable them to perform the required functions.Manufacturing these components from cast metal is fundamentally justified because castings can be produced efficiently in large quantities and possess outstanding mechanical stability. A disadvantage is generally their high weight. The cost-effectiveness of using castings is sometimes limited depending on the molds used, especially with expendable molds. Therefore, there is a general effort, particularly for the caliper housing but also for the brake caliper itself, to find alternatives that allow for cost-effective production and a reduction in the weight of the vehicle's disc brakes without compromising brake stability, and, in particular for sliding caliper brakes, to improve safety.
[0007] From the aforementioned WO2016 / 135316 A1, a brake caliper for a disc brake is known in which the caliper housing or caliper cover is formed from an outer segment, an inner segment running essentially parallel to the outer segment, and two bases extending between the outer and inner segments with corresponding cover elements, each made of sheet metal. It is proposed therein to form at least two of these segments from a single sheet metal element. To attach at least one support element, it is proposed to bring it into contact with the vehicle-side housing wall and then weld them together from the outside through the housing wall. This is said to have the advantage that the vehicle-side housing wall is easily accessible from the outside for a welding robot.
[0008] The reliability of such a joint is questionable. It is desirable to make the operation and / or manufacture of the brake caliper safer yet simpler. Particularly with regard to a caliper cover assembly—i.e., a caliper cover and its attachments, such as a vehicle-side housing wall or a support plate on the opposite side—it is desirable to make operation safer for the brake carrier and / or to simplify the manufacture of the caliper cover and its attachments. Preferably, the caliper cover, and optionally its attachments, should be designed in such a way that operation is safer for the brake carrier and the manufacture of the caliper cover is simplified. This is particularly desirable for a sliding caliper brake, where the safety needs to be improved primarily with regard to a brake caliper that is initially free to move axially.
[0009] This is where the invention comes in, the object of which is to further develop a brake caliper, in particular a caliper cover arrangement or caliper cover, of the type described above, preferably for a sliding caliper brake, in such a way that the disadvantages described above are overcome as far as possible.
[0010] The invention was based in particular on the objective of providing a caliper cover arrangement, especially a caliper cover, which enables a reduction in the weight of the vehicle disc brake without compromising the stability of the brakes. In particular, the safety of a sliding caliper brake should be improved, and it should preferably also be easier to manufacture.
[0011] The problem relating to the saddle cover arrangement, in particular a saddle cover, is solved in a first aspect of the invention by a saddle cover arrangement according to claim 1.
[0012] The invention solves the underlying problem primarily by means of a saddle cover arrangement, in particular a saddle cover of the type described above, which according to the invention is designed with the features of the characterizing part of claim 1.
[0013] The invention thus relates to a caliper cover arrangement for a brake caliper assembly for a commercial vehicle disc brake, comprising at least a caliper cover or at least the caliper cover and one or more attachments such as a vehicle-side support plate, in particular also a brake disc-side housing wall opposite this and / or a vehicle-side housing wall of a caliper housing, which caliper cover is designed to cover a caliper housing from above, wherein
[0014] - a brake disc along a rotational axis from a clamping side to a reaction side with a frame contour of the caliper cover can be overlapped, and wherein the caliper cover has a vehicle-side outer surface associated with the reaction side, and
[0015] - formed with an arc contour in the direction of rotation of the brake disc, extending between opposite edges of the caliper cover in the direction of rotation.
[0016] According to the invention, the saddle cover is formed as a one-piece metallic molded part forming the frame contour and the arc contour of a frame section, in particular as a molded sheet metal part, in particular as being formed partially or completely from sheet metal, wherein
[0017] - the one-piece molded part has a deviating projection at the arc contour, in particular at at least one of the edges, and / or
[0018] - the support plate away from the vehicle has a non-standard projection and / or a raised part extending into the interior.
[0019] The saddle cover assembly comprises, in particular, the saddle cover and one or more attachments such as a vehicle-side housing wall or a support plate on the opposite side of the vehicle. The saddle cover is, in particular, partially or completely made of sheet metal. The one-piece molded part has a deviating indentation, especially on the outside of the frame-like contour. The one-piece molded part has a deviating projection, especially at at least one of the edges of the arc-like contour.
[0020] The invention provides an advantageous design for a caliper cover assembly for a brake caliper of a motor vehicle disc brake, comprising at least one caliper cover in which the attachment of safety elements and manufacturing elements in the manner described is provided on the one-piece molded part – in particular partially or completely formed from a bent and shaped sheet metal – and which can be placed on the caliper housing. The operation of the brake caliper is considerably safer, and the manufacture of the caliper cover is considerably simplified.
[0021] In a second aspect, the invention also leads to a brake caliper assembly according to claim 16 in order to solve the problem.
[0022] The invention also relates to a brake caliper assembly for a motor vehicle disc brake, in particular for a commercial vehicle disc brake with a brake disc moving about an axis of rotation, in particular for a sliding caliper brake, with a brake carrier and with a caliper cover arrangement according to the concept of the invention and with a caliper housing with a cavity for receiving a clamping mechanism, in particular comprising the caliper cover and one or more attachments such as a vehicle-side support plate, in particular also comprising a brake disc-side housing wall and vehicle-side housing wall of the caliper housing opposite the brake disc, which caliper cover is designed to cover the brake carrier on the upper side and overlaps the brake disc from a clamping side to a reaction side and wherein the caliper cover has a vehicle-side outer side associated with the reaction side.
[0023] In particular, the brake carrier includes an outer stop, especially a protrusion. Specifically, the brake carrier has a horn or a knob on its outer surface. The outer stop on the brake carrier is designed to interact with the non-standard indentation or projection of the caliper cover to limit movement of the brake caliper, especially a sliding brake caliper.
[0024] In particular, the clamping mechanism can include a brake lever pivotable about a lever axis, wherein the caliper housing has a vehicle-side housing wall made of a one-piece bent sheet metal, on the inside of which at least one support element for supporting the brake lever is provided. To solve the problem, the invention, in a third aspect, also relates to a commercial vehicle disc brake according to claim 19. The invention thus also relates to a disc brake and / or a motor vehicle with a brake caliper assembly, i.e., with a brake caliper, of the aforementioned type according to the concept of the invention.
[0025] Further developments of the invention are specified in the dependent claims, which further develop the concept of the invention with regard to advantageous features within the scope of the problem statement and with regard to further advantages.

[0036] In a particularly preferred embodiment, the saddle cover 5 is provided that, in the area of an outer perimeter, in particular the edges of the dome section 51 and / or the frame section, the deviating projection has one or more flat sections, wherein a flat section is predefined and distinct from the shape of the one-piece molded part of the saddle cover, such that the flat section forms a contact surface for a clamping or holding tool. A preferred embodiment is explained and described in particular in connection with FIG. 8.
[0037] As described in detail by way of example in the embodiment, it has proven advantageous in a particularly preferred further development that the flat section is formed, attached or molded onto a semi-finished product of the molded part of the saddle cover, in particular embossed or pressed onto it.

[0042] Thus, as described in detail by way of example in the embodiment, it has proven advantageous in a particularly preferred further development that
[0043] - one or more edge sections of the frame section to the window are chamfered with a predetermined chamfer, in particular the chamfer is formed at a predetermined angle to the window surface and / or with a predetermined chamfer width, and / or
[0044] - one or more edge sections of the frame section to the window are rounded and flattened with a predetermined radius, in particular the radius has a predetermined radius value.

[0060] FIG. 1 shows a commercial vehicle disc brake 100 (hereinafter also referred to as "brake 100") designed to decelerate a brake disc attached to a wheel of a motor vehicle (not shown). The brake 100 has a brake actuator 101 designed to generate a braking force in response to a control command. A pneumatic brake actuator is shown, but alternatively, other types of force generation can also be used. The brake 100 has a brake carrier 3 designed to be attached to the vehicle in the area of the axle. The brake 100 has a first brake pad 107.1 on the clamping side and a second brake pad 107.2 on the reaction side. The brake pads 107.1 and 107.2 are attached to a brake caliper 1 according to the invention. The brake caliper 1 shown is a sliding caliper. However, the invention also relates equally to fixed caliper brakes.
[0061] Furthermore, the brake 100 has a caliper housing 103 with a caliper cover 105 made of bent sheet metal, which is mounted on the caliper housing 103 and is designed to engage a brake disc (not shown) that rotates about its axis of rotation R in the direction of rotation D. The caliper housing 103 with a caliper cover 105 made of bent sheet metal is explained in more detail below with reference to a caliper cover 5, 5', 5", 5'" with a brake carrier 3, 3' of a brake caliper assembly or, in short, "brake caliper" 1 according to the concept of the invention.
[0062] In FIGS. 2A and 2B, a brake caliper 1 is shown according to a comparative example, with the caliper cover 5 made of bent sheet metal, i.e., with a caliper cover 5 formed partially or completely from sheet metal. FIG. 2A shows that the brake caliper 1 has the caliper housing 103, which is formed at least partially from sheet metal segments. The caliper housing 103 has the caliper cover 5 made of bent sheet metal, which is placed on the caliper housing 103 and is configured to engage a brake disc (not shown) that rotates about its axis of rotation R. The brake caliper 1 has a first, vehicle-side, housing wall 7, which is designed as a bent sheet metal body. Preferably, the vehicle-side housing wall 7 is oriented at right angles to the axis of rotation R when the brake caliper 1 is mounted in its operating state.
[0063] The caliper cover 5 has an outer surface 6 and an inner surface 8 with respect to the axis of rotation R. The caliper cover 5 is further designed to accommodate a retaining bracket 31 shown in FIG. 2B, which extends from a clamping side 19 of the brake disc to a reaction side 21 of the brake disc and prevents the brake pads from falling out of the brake in a generally known manner.
[0064] On one side of the brake caliper 1 opposite the vehicle-side housing wall 7, a support plate 9 is provided for supporting a reaction-side brake pad (not shown), preferably also made of sheet metal – this support plate 9 is thus designed as a reaction-side pressure plate. Furthermore, on the reaction side 21 of the caliper housing 3, there is a (first) reaction-side bracket 11 for receiving the retaining bracket 31, see FIG. 2B.
[0065] Between the caliper housing 103 and the caliper cover 5, several sliding sleeves 13 are arranged to receive guide pins of the disc brake. The construction of the brake caliper 1 is preferably entirely without cast parts, but may include one or more forged or machined parts.
[0066] The brake caliper 1 has a mounting interface 15, which is designed for attaching a brake actuator, and a number of through-holes 29 for fastening means. The caliper housing 103 encloses a cavity 23 for receiving a clamping mechanism for the aforementioned clamping-side first brake pad 107.1 and reaction-side second brake pad 107.2, which is accessible from the vehicle side by means of a through-opening 25. In the operating state, a plunger of a brake cylinder of the aforementioned brake actuator 101, which is attached to the mounting interface 15, extends through this through-opening 25.
[0067] As can be seen from FIG. 2A, and even more so from FIG. 2B, the caliper housing 103 has a second housing wall 17 opposite the vehicle-side housing wall 7, on the brake disc side, on which a second bracket 27 is provided. The second bracket 27 is shown in a simplified manner in FIG. 2A and FIG. 2B. The hold-down bracket 31 is engaged with the second bracket 27 on the clamping side 19, and with the first support 11 on the reaction side 21, as can be seen particularly in FIG. 2B.
[0068] This first bracket 11 has a hook 11.1 bent away from the clamping side 19, which is integrally formed on the support plate 9, preferably by bending. Once the hold-down bracket 31 is hooked in the manner shown in FIG. 2B, it can be fixed to the saddle cover 5 by inserting a fastener, for example in the form of a screw, into a fastening opening 12 provided for this purpose in the saddle cover 5. The support plate 9, particularly visible in FIG. 2A, is in contact with the inside 8 of the saddle cover 5 with a corresponding contour 33, particularly visible in FIG. 2B, and is positionally aligned by this contour. The support plate 9 is preferably bonded to the saddle cover 5, preferably by welding. The alignment of the support plate 9 on the saddle cover 5 is preferably achieved using a guide shown in FIG.The positioning collar 35 shown in Figure 2B is formed on the support plate 9 by bending it along a bending edge. Preferably, the positioning collar 35 extends in the same direction, namely away from the clamping side 19, along the support plate 9. The bending edge is preferably formed as a circular arc. The contour 33 can be designed for point contact of the positioning collar 35, or for line or surface contact. However, a two-point contact will be sufficient for basic positioning.
[0069] FIG. 3 shows the saddle cover 5 of the comparative example as a one-piece molded part according to the basic concept of the invention with the recognizable support plate 9 on the inside 8 of the saddle cover 5. The saddle cover 5 of the comparative example, in which a frame-like contour and the arc-like contour of a frame section 52 are already formed as a one-piece molded part, can be further improved within the scope of the invention, as will be explained with reference to the following exemplary embodiments of the views in FIGS. 4 to FIGS. 9.
[0070] The improvements are found, according to the following embodiments, particularly in the areas 10, 20, 30 of the saddle cover 5 marked with reference numerals 10, 20, 30, i.e., the outer edge areas 10.1, 10.2 (views of FIG. 4, FIG. 5, FIG. 8), the outer and inner area 20.1, which is associated with the side wall with the outer surface 6 of the saddle cover 5 (FIG. 4A, FIG. 4B and FIG. 5A, FIG. 5B) and the inner area 20.2, which is associated, among other things, with the support plate 9 (views of FIG. 6, FIG. 7), and the inner edge areas 30 of the saddle cover 5 towards the interior 24 (views of FIG. 9).
[0071] Advantageous saddle covers 5', 5", 5'" according to the concept of the invention are described below. These saddle covers have a deviating indentation on the frame-like contour, particularly on the outer surface, and / or a deviating projection on the arc-like contour, particularly at least one of the edges. Furthermore, the advantageous saddle covers 5', 5", 5'" allow for the attachment of safety elements and manufacturing elements to the one-piece molded part in accordance with the invention. For the sake of simplicity, reference is made to existing reference numerals, and the essential improvements relating to the further developed saddle covers 5', 5", 5'" according to the concept of the invention and corresponding to the saddle cover arrangements 50', 50", 50'" of the first, second, and third embodiments are discussed below.
[0072] FIG. 4A shows a first preferred embodiment of a caliper cover assembly 50' improved compared to the comparative example of the caliper cover, with an improved caliper cover 5' which is explained below. This embodiment also has, as explained, a dome section 51 and a frame section 52, with particular reference being made below to the frame section. The frame section 52 is advantageously modified with respect to the aforementioned outer and inner areas 20.1 and the outer edge area 10.1 in order to limit movement of the brake caliper 1. FIG. 4B shows a corresponding side view of the improved caliper cover 5' as part of the improved caliper cover assembly 50', where “O” denotes an outer reaction side (i.e., the outside of the vehicle or facing away from the vehicle), and “I” denotes a clamping side (i.e., the inside of the vehicle or opposite the clamping side).Both FIG. 4A and FIG. 4B are referred to together in the following.
[0073] As can be clearly seen there, the improved saddle cover 5' in the frame section 52 of the one-piece molded part of the saddle cover 5' has a frame-like contour KR with an outer surface A as well as an arc-like contour KB that curves between two edges R1, R2 - a first front edge R1 in the direction of rotation D and a second rear edge R2 in the direction of rotation D. The frame-like contour KR encompasses or borders, so to speak, the saddle cover 5' as its outer contour, and the arc-like contour KB extends in a curved shape between the first and second edges R1, R2 over the underlying interior space 24 of the saddle cover 5'.
[0074] The interior 24, in particular for the brake pads 107.1, 107.2, is accessible via a window F; the window F can be understood as a recess in the arc-shaped contour KB and thus provides access to the interior 24. As can be seen in FIG. 1 and FIG. 6, the window essentially provides a view of a brake carrier 3, 3'. In the side view of FIG. 4B, both the frame-like contour KR and the arc-shaped contour KB are visible from the side, each with the aforementioned outer surface A of the frame-like contour KR and the leading edge R1 of the arc-shaped contour KB in the direction of rotation D, respectively, and the recess in the form of the window F. In other words, the arc-shaped contour KB extends approximately over a caliper housing in the direction of rotation D, and the frame-like contour KR extends circumferentially around the caliper housing above a brake carrier 3, 3'. The frame-like contour KR and the arc-like contour KB merge into each other, especially in the area of their edges R1 and R2, respectively.R2. The arc-like contour KB is also formed on the dome section 51; likewise, the frame-like contour KR can be found on the dome section 51, as can be seen in FIG. 4B.
[0075] According to the concept of the invention, safety elements E1, E2 are now provided on the caliper cover 5' or the caliper cover arrangement 50' in order to limit movement of the brake caliper 1 along the axis of rotation R, which is particularly relevant in the present case for the brake caliper 1 in the form of a sliding brake caliper.
[0076] The first safety element E1 in the outer edge region 10, 10.1 is formed as a projection deviating from the contours KR, KB, namely as a downwardly projecting extension, which is shown in detail in FIG. 5B at the edge R1 of the arc-shaped contour KB. The corresponding further safety element E1 of this type formed at the second edge R2 – specifically designated E1.2 – is visible in FIG. 4A and is designed analogously to safety element E1.1 as a projection deviating from the shape, which is formed as a downwardly projecting extension at the second edge R2.
[0077] Both safety elements E1.1 and E1.2 have a stop B, visible in FIG. 5B, which projects into the interior space 24 on the inside "I" of frame section 52. For the brake caliper 1, designed as a sliding brake caliper, this means that when moving along the axis of rotation R, it cannot move (or slide) further towards the clamping side (i.e., towards the inside of the vehicle) than is permitted by the stop B of the extension of the safety element E1, E1.2, E1.2. The inner boundary surface BFI formed by the stop surface of the stop B is shown as a dashed line in FIG. 4B and is aligned with the stop surface of the stop B of the safety element E1.
[0078] Furthermore, the one-piece molded part of the further developed saddle cover 5' is provided on its outer surface A of the frame-like contour KR with a deviating indentation W, which forms, so to speak, the second safety element E2. In this case, the deviating indentation W extends from the outer surface A of the frame-like contour KR towards corner E; i.e., towards corner E of the frame-like contour KR or of the saddle cover 5'. The safety element E2 thus comprises a safety element E2.1 located at the front in the direction of rotation and a safety element E2.2 located at the rear in the direction of rotation. Both safety elements E2.1 and E2.2 are formed as so-called deviating indentations relative to the otherwise one-piece molded part of the saddle cover 5'. The outer surface A therefore has a raised portion, which is clearly visible in FIGS. 4A and FIGS. 4B at the location of reference numeral A, and also has an inwardly curved area W towards corner E.
[0079] The concave area – i.e., the concave W – is clearly visible in FIG. 4A at the aforementioned corner E of the frame-like contour KR, or the saddle cover 5', whereby the deviating concave W is recognizably formed as an inwardly projecting indentation or depression. This inwardly projecting indentation or depression resulting from the concave W thus forms a second safety element E2, a boundary located on the outside of the vehicle (i.e., in area 0 of the frame section 52). This therefore limits the movement of a brake caliper 1, which is designed as a sliding brake caliper, towards the reaction side (marked 0 on this side).
[0080] The corresponding outer boundary surface BFO is shown in dashed lines in FIG. 4B together with the inner boundary surface BFI. It can therefore be said that the outer indentation W on the outer side A of the frame-like contour KR forms a boundary in the form of the boundary surface BFO for a sliding brake caliper 1 on the outer side 0 – i.e., towards the reaction side – with a corresponding stop for the sliding brake caliper 1 being created by the inwardly projecting indentation or depression of the indentation W. Similarly, the movement of a sliding brake caliper 1 is limited by the safety elements E1, E1.1, E1.2, which are the deviating projections of the downwardly projecting extensions with a corresponding stop surface on the inner side I – i.e., towards the clamping side.
[0081] A sliding brake caliper 1 is positioned in the sliding area BFS shown in FIG. 4B along the axis of rotation R. This protects, firstly, the clamping device in the cavity 23 of the caliper housing 103 on the inside I and, secondly, prevents damage to the caliper cover 5' or to the caliper housing shown in FIG. 1 and at least recognizable in FIG. 4B on its outside 0. In particular, the brake caliper 1 can move slightly forward (against the direction of rotation D) and relatively more backward (in the direction of rotation D) with respect to the center line shown in FIG. 4B as a reference, in order to accommodate the wear of brake pads (e.g., the brake pads 107.1, 107.2 of FIG. 1) and a brake disc. Only limited movement in the forward direction (against the direction of rotation D) protects the boot visible on the right side below the safety element E1.1 in FIG. 6A from damage.Limited backward movement (in the direction of rotation D) protects against excessive wear of the outer brake pad and the outer surface of the rotor. One could also say that, among other things, the indentation W reinforces the caliper cover 5' on the outer surface A, which is structurally evident from the indentation W embossed or dented against the raised outer surface A.
[0082] Thus, the saddle cover 5' offers an improved safety structure in operation, which is ultimately realized by the safety elements E1 and E2 in the manner previously explained.
[0083] Regarding this first embodiment of an improved saddle cover 5', this requirement is illustrated in its functionality in FIGS. 6A to 6C, which are referred to in their entirety in the following explanation. FIGS. 6A to 6C show how a sliding brake caliper 1 is limited in its movement towards the clamping side (i.e., on the inside I) and towards the reaction side (i.e., on the outside 0) along the axis of rotation R.
[0084] The brake caliper 1 is shown here with the brake carrier 3', on which the direction of rotation D for the brake disc (not shown) is also indicated. Also shown for this arrangement of a brake caliper 1 with a further developed caliper cover 5', as described in the first embodiment, are the previously explained safety elements E1 and E2 in the form, on the one hand, the deviating projection as at least one downwardly projecting extension (E1, E1.1) in the outer edge region 10.1 on the inner side I, and the indentation W in comparison to the raised outer side A on that same outer side A of the frame-like contour KR.
[0085] The brake carrier 3', which in this case is specially prepared for the sliding brake caliper according to the further development shown here, has protrusions C1 assigned to the safety elements E1 , E2, i.e. formed for the stop with the aforementioned stop surfaces B for precisely this stop on the outside, for the first safety element E1 and the second safety element E2 respectively.
[0086] In FIG. 6B this is shown more specifically for a position of the brake carrier 3' on the inside I where the protrusion C1 is in contact K1, i.e. in the stop, with the stop surface BF of the safety element E1.
[0087] In FIG. 6C, the corresponding protrusion C2 on the brake carrier 3' is shown for the indentation W forming the second safety element E2. This protrusion is formed here more like a nub or horn on the brake carrier 3'; that is, it abuts the contact surface K2 with the indentation formed by the indentation W. It can thus be seen that the second contact K2 defines the second contact surface for the second, i.e., outer, contact surface BFO, and the first contact K1 defines the first, i.e., inner, contact surface BFI.
[0088] Referring to FIG. 7 A and FIG. 7B, an embodiment modified from the first embodiment is shown for forming a first safety element E1 or a second safety element E2 with corresponding stops B.
[0089] Figure 7A shows that, in addition to or alternatively (in this case additionally) to a concave section W on the outer surface A of a saddle cover 5', 5", a raised portion can be formed on the saddle cover 5', 5" or on a support plate 9 itself, and / or it is the support plate 9 itself that rests on the raised portion on the saddle cover 5', 5" to serve as a second safety element E2. This may, but does not necessarily, involve a corresponding concave section W on the outer surface A of a saddle cover 5', 5" or the support plate 9.
[0090] A stop can therefore be formed by means of a bead (e.g. in the form of the aforementioned raised part on the outside A or the support plate 9 itself).
[0091] In general, however, an area serving as a second safety element E2 - so to speak as a forward-positioned contact area K2 located on the outside 0 - can be designed to limit the outward movement of a brake caliper even without the indentation W on the outside A of a caliper cover 5', 5".
[0092] Figure 7B further shows a first safety element E1, which is also formed as a non-standard projection. Here, the downwardly projecting extension is visibly attached to the frame contour KR in a joining area FB with a corresponding element (for example, by welding or brazing – thus attached and less integrally formed with the frame contour KR of frame section 52). Such an extension can also be attached to the support plate 9 itself.
[0093] In an embodiment shown in more detail in FIGS. 7C and 7D, a safety element E2, E2.1 can also be implemented simply by an extended support plate 9 for a brake pad; a stop forming the safety element E2, E2.1 is then located on the support plate 9 itself or is formed by means of the support plate 9 itself, so that the aforementioned indentation W on the outer surface A in conjunction with the protrusion on the caliper cover 5"" (for realizing the aforementioned raised part of the support plate 9, which projects into the interior 24) is essentially unnecessary. FIG. 7C shows this embodiment in which the caliper cover 5"" does without indentation W and the support plate 9 has a non-standard projection and / or a raised part projecting into the interior 24 to form a safety element E2, E2.1.
[0094] In other words, the support plate 9 shown in FIGS. 7C and 7D can point towards the location of the contact surface K2 of FIG. 7A; the contact surface K2 points towards the bearing surface of a brake pad. The aforementioned indentation W on the outer surface A in conjunction with the protrusion can then, in my opinion, be omitted. The embodiment shown here in FIGS. 7C and 7D therefore optionally includes a separate plate or alternative support plate that closes a gap between the caliper cover 5 and the support plate 9 – as can be seen in FIGS. 2A, 4A, 6A and 7A.
[0095] FIGS. 8A, 8B, and 8C show a second embodiment of a saddle cover assembly 50" for a saddle cover 5". Here, too, the same or similar features or features with the same or similar function are used, and reference is again made to the previously mentioned reference numerals. In the following, particular reference is made to the differences compared to the example in FIGS. 2 and 3.
[0096] The second embodiment of a saddle cover 5" is further developed in a particularly advantageous way for manufacture by means of the manufacturing elements H1 , H2 shown here on the frame-like contour KR, wherein here too a shape-deviating indentation is provided on the frame-like contour or a shape-deviating projection is provided on the arch-like contour.
[0097] These areas 10, 20 are – as already shown in FIG. 3 – marked with corresponding outer edge areas 10.2 and inner area areas 20.2. At least in part, the manufacturing elements H1, H2 shown here can also be used on the frame-like contour KR as safety elements E1 and E2, respectively.
[0098] It is provided that the further developed saddle cover 5” in the area of an outer perimeter, i.e. at the edges R1 , R2 - in this case of the dome section 51 with regard to the manufacturing elements H1 and of the frame section 52 with regard to the manufacturing elements H2 - has precisely that shape-deviating projection as one or more flat sections.
[0099] The flat sections are shown in FIGS. 8A, 8B, and 8C as the front flat section H1.1 in the direction of rotation D and as the rear flat section H1.2 or H2.1 / H2.2 in the direction of rotation D. Specifically, a flat section H1, H2 is always edged in a predetermined manner and is distinct from the shape of a one-piece molded part of the saddle cover 5". The separation is such that the flat section H1, H2 forms a contact surface on which a clamping or holding tool can engage—or, more generally, be applied.
[0100] It has been shown that, in the case of a one-piece forming process, it should nevertheless be ensured during manufacturing that the saddle cover 5" can be gripped by appropriate machine gripping or holding tools, even with its radii of curvature and bulges. Less curved areas are preferably suitable for this purpose; however, these are only partially present or accessible in the further developed saddle cover 5" as a one-piece molded part. The advantageously designed flat sections H1, H2, however, can also be gripped by appropriate machine gripping or holding tools.
[0101] A flat section H1, H2 shown here can be molded onto, attached to, or embedded in a semi-finished product of the saddle cover 5", in particular pressed onto, attached to, or embedded in the molded part. A molded-on manufacturing element H1 and a pressed-in manufacturing element H2 are clearly visible in the view of FIG. 8C at the edge R1 of the frame contour KR.
[0102] A third preferred further embodiment shows a saddle cover 5'" of a saddle cover arrangement 50'", wherein the saddle cover 5'" is again formed with a dome section 51 and a frame section 52. The frame section 52 again has, as previously described, an arc contour KB extending between two edges R1, R2 and thus arches over a saddle housing (not shown) and therefore overlaps the interior 24.
[0103] Access to the brake carrier 3, 3' (as shown in Fig. 1) or the brake linings (not shown) is provided by a window F in the arc contour KB of the frame section 52, wherein the window F forms one or more edge sections of the frame section as a recess in the arc contour KB. As can be seen in FIGS. 9A, 9B and FIG. 90, the edge sections are formed in the direction of rotation (i.e., running transversely to the direction of rotation D) by means of the rear edge section FK2 or the front edge section FK1 (not shown). FIG. 9B shows a first modification of the third embodiment in which such an edge section FK2 is flattened in a predetermined manner. Accordingly, in a first variant, a flattening is provided in a predetermined manner on the rear edge section FK2 by means of a predetermined radius, i.e.in this case as a radius FKR formed in a predetermined manner at the edge section of the frame section 52.
[0104] FIG. 90 shows a second modification of the third embodiment, in which such an edge section FK2 is flattened in a predetermined manner. In the case of FIG. 9C, the edge section FK2 is provided with a chamfer FKF formed in a predetermined manner towards the window F, i.e., practically as a chamfered edge section. The chamfer FKF can be seen in FIG. 9C on the rear edge section FK2.
