    [001] The present invention relates to a fixed caliper brake for a motor vehicle, as well as a respective brake pad for a fixed caliper brake.
    [002] Fixed caliper brakes normally comprise a caliper-shaped casing with two casing arms and a casing bridge for the flexural-resistant connection of the casing arms at a defined distance from each other. In an intermediate space (distance a) between the frame arms, in partial-pad disc brakes, a segment of a rotor is always received, in other words, a segment of a brake disc, together with the brake pads, which request the thread. In the frame arms, pistons are received, most of the time hydraulically or electromechanically actuated, axially guided in relation to the brake disc, in piston holes. In addition, carcass bridge carcass arms define a compartment, open radically from the outside, for easy changing of brake pads. To receive rotational forces, the compartment has abutment surfaces in the brake disc outlet region, for a so-called compressed abutment of the brake pads. When the fixed caliper is fixed to a motor vehicle axle trunnion, it is possible to generate a braking effect, by the fact that the pistons are displaced with defined normal force, preferably hydraulically or electromechanically towards the friction surfaces of the brake disc, so that frictional or rotational forces are introduced through the brake pads in the housing. For the radial fixation of the brake pads, pins are normally used, which go through the holes in the brake pads and are mounted in holes in the housing. This prevents the brake pads from being unintentionally removed from the housing. In order to avoid chattering noises, a spring with spring arms can be provided, which engages the brake pads with pre-tensioning force in a permanently elastic way in a stop.
    [003] The invention is based on the task of proposing a fixed caliper brake, or a brake pad, for use in a fixed caliper brake, which, in each case, optimally satisfy the requirements existing at the time, particularly , in terms of higher resistance, reduced residual braking moments, maximized brake pad surface, reduced weight, reduced costs and improved appearance. To solve the proposed foot problem, in each case, a fixed caliper brake, or a brake pad according to the invention. In detail, a fixed caliper brake is proposed, whereby the brake pads are supported, at least on the inlet side, as well as with a positive union, on the frame bridge. Another aspect of the invention relates to a brake pad, with a brake pad and with a brake pad backplate, the backplate being formed, at least on the inlet side, with an arm comprising a hook-shaped, radially outwardly open, and the back plate serving, at least in part, for positively joining a housing section. The stretched back plate and a power support on the frame bridge further enable an improved configuration in noise behavior (NVH) and protected against corrosion as well as fouling. Other details of the invention are shown along with the description, by means of the drawing.
    [004] The drawings show:
    [005] Figures 1 - 17 fixed caliper brakes, elastic spring of the same, as well as brake pads, in each case in different modalities and representation in the drawings.
    [006] A fixed caliper brake 1 for a motor vehicle can be releasably attached to an axle trunnion of a motor vehicle, and comprises a frame 2 formed in one piece (monoblock frame), with two frame arms 3, 4, positioned substantially laterally, formed substantially completely closed, at least on one side of the edge, plateau-shaped, and with a frame bridge 5, which connects the frame arms 3, 4, so rigid to flexion, with a defined distance from each other. A flat, closed contour of the carcass arms 3, 4 gives a special appearance, aesthetically closed and harmonious, which is particularly also suitable for efficiently applying figurative elements to the public, such as, in particular, manufacturer's emblems. The formed, substantially completely closed carcass bridge 5 ensures high flexural rigidity and harmonizes with a total closed appearance of the carcass arms 3, 4. Technical effect (strength) and aesthetic form an optimized symbiosis, with production being described in more detail in detail below. The bridge housing 5 formed extensively closed - no withdrawal opening for brake pads 6, 7 overlies the brake pads 6, 7 and a brake disc not shown in an outer radial region. In the frame arms 3, 4 are received pistons 13, 14 in holes 8, 9, axially displaceable along axis A. In addition, brake pads 6, 7 are received in frame 2, guided axially displaceable way . Rotational forces are supported in the peripheral direction on housing 2. Each brake pad 6, 7 comprises a friction mass 10, which is fixed substantially centrally over a central section 12 of a back plate 11. Each brake pad 6, 7 , can be operated directly by at least one of the pistons 13, 14. The rear plate 11 has arms 15, 16 - substantially opposite and which, in each case, leaving the central section12, pointing laterally in a peripheral direction, and which, in each case consists of arm sections 42, 43, which serve to support the traction of the rotational forces in frame 2.
    [007] To enable this support called traction (pull) of the brake pads 6, 7, it is provided that each back plate 11 is supported on the inlet side as well as with positive union in a radially external region on a support surface 17, 18 defined, worked in a flat manner, of the frame bridge, which works as a counterbody for the introduction of force. Furthermore, it is defined that each rear plate 11 of a brake pad 6, 7 has on the inlet side at least one hook-shaped arm 15, 16, pointed radially outwards, which with the arm section 42 initially extends in the circumferential direction which then with the arm section 43 is directed radially outwards, parallel to the abutment surface 1, 18 of the frame bridge 5, to receive radially outwardly a section of the frame bridge 5. Thereby a backrest protected against dirt and corrosion (in view of thrown dirt) for the brake pad supported by traction. Each arm 15, 16 may be formed particularly in the form of a hammer head, a hammer head tip pointing radially outwards. Ideally, an attack point X of the introduction of force into the housing 2 is aligned with a surface center of gravity Y of the friction mass 10, such that the brake pad 6, 7 does not, in principle, show any tendency to rotation, because no pair of forces is formed, so that consequently no parasitic rotational action is formed. In other words, by the geometric positioning and dimensioning of the back plate 11, as well as by the geometric formation of the friction mass 10 in relation to the ideally input of force on the frame bridge 5, a minimization of rotational tendencies is made possible. If, at the base of the geometric relations, an imaginary point of attack X of the friction forces is arranged, with radial distance from the surface center of gravity, a pair of forces is defined, in a certain way, so that the brake pad 6, 7, with its end on the outlet side radially outwards, it tends to an additional abutment on the frame bridge 5. In this case, abutment surfaces 19, 20 arranged parallel to the circumferential direction u, on the arm 15, 16 serve as support. For the formation of a defined stop, additionally on the output side, of the brake pads 6, 7 - or for an independent support of the running direction of the brake pads 6, 7 - the additional arms, arranged in each case, on the side are used. exit on the back plate 11. All the arms 15, 16 have, in addition to an extension in the circumferential direction u, an abutment surface 17, 18, at least radially outwardly directed.
    [008] To prevent chattering noises, at least one spring element 21 is provided, which can be fixedly disposed in the housing, and which permanently elastically forces the two brake pads 6, 7 with at least one spring arm 22, 23, so that they are compressed radially outwardly into abutment in their receptacle in housing 2. Details and alternatives are explained in the text below.
    [009] The modality of a fixed caliper brake 1 described above is intended, particularly, for light passenger cars, for motor vehicles additionally braked in a recuperative mode, or for use in the region of a rear axle, because these applications primarily require moments comparatively small braking force and circumferential forces or limited energy transformation or, when only one-sided (input-side) force support of circumferential forces may suffice.
    [010] An alternative fixed caliper brake mode 1 enables increased energy transformation and higher braking moments or decreased surface pressure at the attack points, by the fact that the force flow is divided, so that additional attack points X1, X2 can be used. In this way, the forces are not only introduced at one end on the inlet side - in a way, with the rear plate 11 requested exclusively for tractive force, but for particularly high braking moments, a support of the rear plate 11 is made possible. in a way, compressed (push). In this case, each back plate 1 can be formed almost elastically and present on the arm, in each case on the outlet side, an additional abutment surface 24, 25, such that it is provided, at least for high stresses, an additional attack point X2 for introducing frictional forces (circumferential forces) into a frame-shaped widening 26, 27 of the frame bridge 5. Thereby, the force flow is somewhat divided, with a first proportion of force can be introduced at the point of attack X1, on the inlet side of a stop surface 29, and an additional proportion of force, particularly in the case of high circumferential forces, can be introduced on the outlet side, on the attack point X2 on an abutment surface 30. Depending on the dimension of a tolerance between abutment surfaces 17, 18; 24, 25 on the back plate and the associated abutment surfaces 29, 30 on housing 2, the support can be arranged gradually differently (pull support and additionally push support, starting with small circumferential forces or pull support on the case of small circumferential forces and additionally push support from higher circumferential forces). A low-cost work on abutment surfaces 29, 30, 31, 32 of the housing 2, extending radially, provides that a single tool (milling or countersink) is formed and dimensioned in such a way, with the tool being guided in such a way by the widening 26, 27 of the carcass, which has two abutment surfaces 29, 31; 30, 32 can be worked simultaneously with chip lifting, with a tool feed movement.
    [011] In principle, it is possible that the circumferential forces of the rear plate 11 are immediately introduced directly into the corresponding x1, x2 strike points of the frame bridge 5. But, for various reasons, it may be advantageous to configure this force input indirectly, by interleaving a reinforcement 28, in that, for example, a comparatively thin sheet of stainless high-alloy steel sheet material is placed on the bearing surface. Because, in this way, a possibility is created to exert influence on the conditions of contact force and friction between back plate 11 (steel plate material) and frame bridge 5 of the fixed caliper (casting material, such as, particularly , gray casting or cast steel or light metal alloy), and avoid immediate direct contact of components. Furthermore, corrosion behavior or insensitivity to dirt can be positively influenced. A particularly advantageous configuration is given when the housing 2 of the fixed caliper is formed of light material, originally formed in one piece - therefore cast - in a sand casting process or in a die casting process and the holes 8 , 9 are inserted by lifting chips, by appropriate measures in the frame arms 3, 4 by the fact that a tool is introduced in the intermediate space between the frame arms 3, 4, which, after the complete assembly of the fixed caliper, receives the brake pads 6, 7 and the brake disc. In this context, it is also advantageous when all the holes 8, 9 are arranged, in each case, aligned with one another and precisely arranged opposite each other in the frame arms 3, 4, and the distance being defined between the housing arms 3, 4 are formed at least slightly longer than the length of a piston 13, 14, so that a bolt-on multi-part configuration of the fixed caliper can be dispensed with. In the hydraulically operated variants of a fixed caliper brake 1, further work steps can consist of providing hydraulic connection holes 33 or additional connections 34. This particularly concerns vent holes for one or more hydraulic pressure chambers 35, as well as the production of one or more connecting holes 33 between several hydraulic pressure chambers 3 . Whenever a frame arm 3, 4 has several holes 8, 9, connection holes of this type between hydraulic pressure chambers 35 are required.
    [012] Another measure necessarily necessary in fixed decaliper brakes 1 consists in the fact of providing at least one hydraulic connection 36 between opposite hydraulic pressure chambers35 in the opposite frame arms. This hydraulic connection 36 can be internally guided, therefore, starting from a pressure chamber 35 in a frame arm 3, 4, or starting from a connection hole 33 between pressure chambers 35 in this frame arm 3, 4, through the frame bridge 5, to a hydraulic pressure chamber 33a in the frame arm 3, 4 arranged on the opposite side, or to a connecting hole 33a between pressure chambers 33a,33b in that frame arm, so that the guide of the hydraulic lines is planned in a fully integrated way. However, if an immediate point-to-point connection is not possible, due to a geometric configuration of the fixed caliper brake 1, it may be appropriate and necessary to form the connection holes segmentally, from multiple hole sections, and where the hole sections are aligned at an angle to each other. As for the production of the corresponding hole sections there remain in the housing at least unwanted tool inlet openings and, optionally, also unwanted tool outlet openings, it can be provided that, after hole production, hole cleaning and/or surface treatment, they are provided with a closure means. In the preferred case, the closure means are formed as spheres, the diameter of which is dimensioned slightly larger than the diameter of the hole, so that by compressing the hole a hydraulically hermetic closure of the tool inlet openings and tool openings is produced. tool output. It may also be envisaged to tamp down the closing means, particularly balls, alternatively or in addition to the compression, with the carcass material, whereby force introduction points are provided, uniformly distributed on the circumference, which are visually perceptible by markings. compression.
    [013] As an alternative to a fully integrated line guide, a conventional pipe connection, externally attached, between the frame arms 3, 4, can be provided, which allows a reduced chip lifting work. Mixed shapes are conceivable due to the fact that, for example, the pressure chambers 35 in a housing arm 3, 4 are connected by internal connection holes, and the two housing arms 3, 4 being supplied by a attached piping connection.
    [014] Although electromechanical wheel brakes comprise, in principle, a totally different active energy, the supply of electrical energy takes place by means of electrical line guidance, in principle, analogously to the hydraulic active energy supply - as described above.
    [015] As explained above, a brake pad 6, 7seats radially from the inside on the bridge housing of the fixed caliper brake 1, so that there is a guide and protection against loss in the radially outward direction. In the radially inward direction, normally, a constructively existing brake disc cup (wheel hub) prevents a fall out of the brake pads 6, 7, so that, in this way, a protection against constructive loss, efficient by positive union and also protected against falling out. An exchange of the brake pads 6, 7 is carried out by the fact that the brake caliper is dismantled from the axle journal, and the brake pads 6, 7 are removed from the housing 2, after having removed the shaft element. spring. According to various embodiments of the invention, the spring is provided in each case in such a way that the brake pads 6, 7 are pulled or pressed in the guide in a permanently elastic way radially outwards. The at least one spring element 21 under elastic pretension, is provided between piston 13 14 and/or housing 2 and brake pads 6, 7, and forces at least one or two brake pads 6, 7 radially outwards, towards the 5th frame bridge.
    [016] In this context, in principle, in detail, several alternative variants for a spring are possible: a) spring element(s) 21, provided integrally fixed on the back plate 11 of one or two brake pads 6 , 7 - for example, by engaging a piston 13, 14 in the form of a cupb) spring element(s) 21, provided for the two brake pads 6, 7 fixed integrally to housing 2.
    [017] In the modes integrated in the brake pads (type a)), a form of construction is presented, which consists in the fact that the back plate 11 has at least one spring arm 39 for engagement with a piston 13, 14 cup-shaped, and the elastic effect is directed radially outwards.
    [018] In another preferred solution (type b)) a spring element 21 is arranged in the housing 2 radially inside, in the region of a brake disc cup, and compresses the brake pads 6, 7 radially outside on the guide the same. The spring element 21 can be provided to be fixed, particularly releasably. As an example only, a screwing of the spring element 21 in the housing 2 is given.
    [019] A spring element 21 can be produced from steel wire or a flat steel plate, substantially transformed without lifting of chips and present a corresponding plate configuration, with reinforcement 52 in the form of ribs, directed axially. For fastening the spring element 21, an arrangement for screwing or engaging the housing 2 is particularly suitable, as an example, at least one locking section 37 of the spring element 21 slides over an associated guide 39 and thereby it can engage with an axially directed insertion movement, with positive coupling, into or behind at least one cavity or recess 38 of the housing 2, so that an axially directed mounting of the spring element 21 is made possible. Mounting takes place by the fact that the brake pads 6, 7 are inserted into the housing 2 and then the spring element 21 is inserted parallel to the axial direction ax, through an opening 40 of the back plate 11, before mounting takes place. of frame 2 on the motor vehicle.
    [020] The housing 2 has at least one cavity, preferably a mounting, spring or hook fastening for positive union reception of a locking section 37 of the spring element 21. Subsequently to an integrated guide39, the section of locking 37, after reversible elastic deformation, elastically engages with positive coupling in a recess 38 of housing 2. In this way, spring element 21 is arranged fixed to housing 2.
    [021] The spring element 21 can take on additional tasks, particularly by a component according to Figure 17, along with the following features. Because the spring element 21 is formed for fastening a support element 46, it can additionally serve to support at least one other component. For example, the support element 46 may have arms 50, 51, which secure one or more BBW brake pad wear warning device conductors 47, 48 (alert contacts) in such a way elastically to the frame 2, that these conductors 47, 48 are arranged, for example, in the region of a visible front or bridge surface of the housing 2, optically attractively guided as well as inexpensively, and protected against abrasion, damage etc. Furthermore, by the simple measure according to the invention, an unintentional withdrawal of an eventual plug-in connection can be safely prevented. A separate measurement is not necessary for a known tubular component, such as in EP 602866 B1. According to the invention, the rod-shaped spring element 21, extended parallel to the axial direction ax, has a multiple function. Separate fastening means between support element 46 and housing 2 are further omitted. The invention is thus particularly advantageously suited to solutions in which each wheel brake is placed in each case on both sides. of a brake disc, at least one separate warning contact for monitoring the wear condition of a frictional mass 10. Between spring element 21 and support element 46, at least one elastic locking device 49 can be provided, which advantageously , has several arms, which serve for the releasable attachment of the support element 46. Preferably, the attachment is released in such a way that the support element 46 engages in a cavity of the spring element 21.
    [022] The brake pads 6, 7 may be provided, in combination, according to figures 3, 4, 5, 13, 14, with all the mentioned characteristics, or, in each case, individually, with the following characteristics . At least one of the arm sections 42, 43 of the back plate 11 may have a thickness t1 which is formed greater than a thickness t2 of the central section12 of the back plate 11. As the placement of the thickening t1 increases a traction cross-section. tension, substantially over the entire height H thereof in the region of the existing tensile stresses, an introduction of reduced tensile stress in undercut effect is made possible in the arm sections 42, 43. According to the invention, by at least one process of cold transformation of the back plate 11 the problem of feeding an additional material volume for the production of thickening in the tension-free cross section of the arm sections 42, 43 is solved. The system is thus sufficiently distinguished from the design base plate of a known hammer head-shaped backplate, substantially thickened only partially in the region of a bearing surface, for a caliper. floating per piece according to EP 1 217 247 B1 wherein the free end is thickened substantially on the edge side in the region of a counterbody support (support), mainly to form an enlarged support surface for the counterbody, so that the surface compression is reduced in the region of this support.
    [023] For all modalities of frame 2 of caliperfixed brake 1 it is, in principle, that a fixation between shaft journal, not shown, and frame 2 can take place under reciprocal adaptation of the intersection point, with the help of means radially directed fixing holes (screws) or a mixed form of these variants, and the fixing means being guided by fixing holes correspondingly aligned in the housing 2. In principle, however, for application or adaptation to different mounting situations in a motor vehicle, it is conceivable to provide a modular system of intersection points, such that the frame 2 has, in principle, only fixing holes for the radially aligned fixing means, and that a "standard" frame of this type a separate supplementary part 41 (adapter) is associated, to enable, with little complexity, an adaptation to motor vehicles with an axially or inversely directed fixing intersection point. By the supplementary part 41, additional costs are saved for a production of several casting molds in an optically acceptable way, and standardization is promoted. In this way, advantages result in the rationalization of mechanical production.REFERENCE SIGNAL LIST1 fixed caliper brake2 housing3 ,4 carcass arm5 carcass bridge6 ,7 brake pad8,9 hole10 friction mass11 rear plate12 center section13 , 14 piston15 , 16 arm17-20 abutment surface21, spring element22, 23 spring arm24, 25 abutment surface26, 27 flare28 reinforcement 29-32 stop surface33 connecting hole34 connection35 pressure chamber36 connection37 locking section38 recess39 guide40 opening41 supplementary part42, 43 arm section44 , 45 spring arm46 support element47 driver48 driver49 coupling device50 arm51 arm52 distance reinforcementA axisH height / Hm average heightax axial direction circumferential direction radial directiont1, t2 thicknessx, x1, x2 point of attackY surface center of gravityBBW warning device for cold insert wear (alert contact)
