Description

Technical Field

[0001] The invention relates to an electromechanically operated floating caliper brake for a motor vehicle, in particular a passenger car. The invention also relates to an electromechanically driven motor vehicle having such a floating caliper brake. These include both floating caliper brakes that are operated only electromechanically and floating caliper brakes that are operated hydraulically and additionally electromechanically. The second case is common in brakes that are hydraulically actuated during driving operation and electromechanically actuated to fix the position of the vehicle in question. In the case of floating caliper brakes that are operated only electromechanically, the actuator piston is actuated by means of an electric motor and in most cases combined with a gear transmission assembly. In the case of a combined solution, the actuator piston can be moved both hydrostatically and by means of an electric motor and a gear transmission assembly. Background Art

[0002] Floating caliper brakes are usually designed as fist-type floating caliper brakes, in which the floating caliper is of the fist type. The fist-type caliper, which is mounted in an axially floating manner, has a piston area and a finger area. The brake disc and the brake pad are arranged inside the "fist", between the finger area and the piston area. The inner area of ​​the fist together with the brake carrier forms a chamber in this area, in which the brake disc is positioned when installed in a motor vehicle. The floating caliper is mounted in such a way that it can be axially displaced relative to the brake carrier.

[0003] Electromechanical drives take up more installation space than hydraulic drives. They also generally have a higher weight than hydraulic drives. However, the installation space available in the area of ​​the wheel rim and wheel mounting or wheel suspension is limited. There is also a trend towards having to accommodate additional components in the area of ​​the floating caliper brake, such as brake covers or brake dust collectors. If powerful floating caliper brakes are required, as is often the case for front wheel brakes or relatively large passenger cars, the problem of high bearing forces between brake carrier and floating caliper also arises (especially with electromechanical units that protrude a lot). In conjunction with the development of purely electromechanically driven passenger cars, the demand for wheel brakes that are also operated purely electromechanically is increasing. As a result, the scope of use of hydraulic actuation is also decreasing in brakes where high braking powers must be achieved. Summary of the invention

[0004] The object of the present invention is therefore to provide a powerful, electromechanically operated floating caliper brake which is suitable, for example, for front wheel brakes and / or large passenger vehicles, such as SUVs, and which is optimized with regard to installation space to the extent that it can be better installed in the area of ​​the wheel rim and wheel mounting or wheel suspension.

[0005] The floating caliper brake comprises at least one actuator piston for displacing at least one brake pad unit, at least one electromechanical drive for actuating the actuator piston, a brake carrier and a floating caliper. The floating caliper has a piston area and a finger area. The floating caliper brake extends in an axial direction so that the piston area is on a first side of a brake disc that can be accommodated in a chamber formed by the brake carrier and the floating caliper, and so that the finger area is on a second side of the brake disc that can be accommodated in the chamber, opposite to the first side. The expression "in an axial direction" relates to the orientation of the axis of rotation of the associated brake disc, which rotates around the axis of rotation when installed in the floating caliper brake and during driving operation of the associated motor vehicle. That is, "in an axial direction" means extending parallel to or along the axis of rotation. The first guide assembly is arranged on the third side, spaced apart from a center plane, which extends in line with the axis of rotation of the brake disc that can be accommodated in the chamber. The first guide assembly extends along a first guide axis, which extends in the axial direction and is parallel to the axis of rotation. The second guide assembly is arranged on a fourth side, spaced apart from the center plane, and extends along a second guide axis, which extends in the axial direction and parallel to the axis of rotation, with respect to the center plane. The first guide assembly has a first guide channel, which is surrounded by the brake support; a first guide element, which is guided in the first guide channel so as to be displaceable in the axial direction and has a first guide axis and a first fastening end; and only one first connecting part, which is connected to the floating caliper, preferably connected to the floating caliper in one piece. The first guide element is fixedly connected to the first connecting part by means of its first fastening end. The connection is preferably a screw connection. The first connecting part is located at the level of the finger-shaped area in the axial direction. The connecting part can also be located at least partially on the second side. The above-mentioned two positions of the first connecting part can also exist simultaneously. The design according to the invention, in which the first guide assembly has only one connecting part (i.e., the first connecting part) connected to the floating caliper at the said position, leads to a design of a floating caliper brake that is optimized in terms of installation space.

[0006] Preferably, a first installation space is available on the first side adjacent to the first guide assembly aligned with the first guide axis. A first installation space can also be available in the axial direction at the level of the piston area. The above two positions of the first installation space can also exist simultaneously. The installation space is generated by the interaction with the arrangement of the single first connecting part.

[0007] Preferably, the electric motor is at least partially arranged in the first installation space. The electric motor is used to actuate the actuator piston. The transmission can also be at least partially arranged in the first installation space. The housing of the electromechanical drive can also be at least partially arranged in the first installation space. Preferably, the electric motor and the transmission cooperate as an electromechanical drive, with which the actuator piston can be actuated. Preferably, the transmission is connected between the electric motor and the actuator piston. The electronic control unit can also be at least partially positioned in the first installation space. Such an electronic control unit can preferably be designed to control the electric motor that actuates the actuator piston. Such an electronic control unit can include a PCB, electronic components and preferably a CPU. An electrical interface can also be arranged in the first installation space. Such an electrical interface can be designed to connect a data line or a control line or to connect a power line. It can also be designed to connect a data line, a control line and a power line. The interface can be in the form of a plug or a socket. Components or component areas of the brake cover can also be arranged in the first installation space. Components or component areas of the brake dust collection device can also be arranged in the first installation space. Preferably, several of the above-mentioned components or assemblies can also be arranged at least partially in the first installation space. The advantage is that the first installation space is fully utilized. As a result, components for powerful brakes can also be positioned close to the floating caliper. This has a favorable effect on the bearing forces (lever length is shortened). Overall, this also allows the necessary components to be accommodated in the area of ​​the rim and wheel mounting or wheel suspension.

[0008] Preferably, the floating caliper brake comprises a brake cover, which is fastened to the floating caliper by means of the first fastening end. The brake cover can also be fastened to the first fastening end or to the first connecting part. The brake cover can also be fastened to both the first fastening end and the first connecting part. Preferably, the brake cover has a first retaining part, which is clamped between the first connecting part and the first fastening end. The first fastening end can include a screw, by which the first retaining part is fixed against the first connecting part. Preferably, the first retaining part has a channel, through which the screw passes for this purpose. By means of the above-mentioned possibility of fastening the brake cover, a design of the floating caliper brake is achieved that is optimized in terms of installation space. In this case, the fastening part for coupling the brake caliper and the brake support is also used at the same time to fasten the brake cover. This saves installation space and is an economical solution. It also allows an aesthetically attractive design of the brake cover. Such a brake cover can be a protective cover, a logo plate or part of a brake dust collection device. It can also be a stabilizing plate. Several or all of the above-mentioned functions can be realized in the brake cover.

[0009] Preferably, the first guide channel has a first end and a second end and extends along a first guide axis between the first end and the second end, wherein the first end is arranged closer to the piston area than to the finger-shaped area in the axial direction, and wherein the second end is arranged closer to the finger-shaped area than to the piston area in the axial direction, wherein the first end is closed and the second end is open, and wherein the first guide element extends into the first guide conduit with its guide axis (i.e., the first guide axis) through the opening of the second end.

[0010] In a preferred embodiment of the floating caliper brake according to the invention, the second guide assembly has: a second guide duct, which is surrounded by the brake carrier; a second guide element, which is guided in the second guide duct so as to be displaceable in the axial direction and has a second guide shaft and a second fastening end; and only one second connecting part, which is connected to the floating caliper, in particular connected integrally to the floating caliper. In this preferred embodiment of the floating caliper brake, the second guide element is fixedly connected to the second connecting part by means of its fastening end, preferably screw-fastened to the second connecting part. The second connecting part is located at the level of the piston area in the axial direction or at least partially on the first side. The above two positions of the second connecting part can also exist simultaneously. This embodiment of the floating caliper brake leads to a particularly suitable force transmission between the brake carrier and the floating caliper. That is, as a result, the large weight of the electromechanical drive is supported in a suitable manner and dissipated via the first guide assembly and the second guide assembly, so that relatively low stresses caused by the effective forces occur in the relevant components.

[0011] Preferably, the second guide channel has a third end and a fourth end and extends along a second guide axis between the third end and the fourth end, wherein the third end is arranged closer to the piston area than to the finger-shaped area in an axial direction, and wherein the second end is arranged closer to the finger-shaped area than to the piston area in an axial direction, wherein the third end is open and the fourth end is closed, and wherein the second guide element extends into the second guide duct with its guide axis (i.e., the second guide axis) passing through an opening at the third end.

[0012] In another preferred embodiment of the floating caliper brake according to the invention, the second guide assembly has: a second guide duct, which is surrounded by the brake carrier; a second guide element, which is guided in the second guide duct so as to be displaceable in the axial direction and has a second guide shaft and a second fastening; and only one second connection part, which is connected to the floating caliper, in particular connected integrally to the floating caliper. In this preferred embodiment of the floating caliper brake, the second guide element is fixedly connected (preferably screw-fastened) to the second connection part by means of its fastening end (i.e., the second fastening end). The second connection part is located at the level of the finger-shaped area in the axial direction or at least partially on the second side. The above two positions of the second connection part can also exist simultaneously. This embodiment in which the first guide assembly has only one connection part connected to the floating caliper (i.e., the first connection part) at the aforementioned position and the second guide assembly has only one connection part connected to the floating caliper (i.e., the second connection part) at the aforementioned position leads to an extended design of the floating caliper brake optimized in terms of installation space.

[0013] Preferably, a second installation space is available on the first side adjacent to the second guide assembly aligned with the second guide axis. A second installation space can also be available in the axial direction aligned with the second guide axis at the level of the piston area. The above two positions of the second installation space can also exist simultaneously. The installation space is generated by the interaction with the arrangement of the single second connecting part.

[0014] Preferably, the motor is at least partially arranged in the second installation space. The motor is used to actuate the actuator piston. The transmission can also be at least partially arranged in the second installation space. The housing of the electromechanical drive can also be at least partially arranged in the second installation space. Preferably, the motor and the transmission cooperate as an electromechanical drive, with which the actuating piston can be actuated. Preferably, the transmission is connected between the motor and the actuator piston. The electronic control unit can also be at least partially positioned in the first installation space. Such an electronic control unit can preferably be designed to control the motor that actuates the actuator piston. Such an electronic control unit can include a PCB, electronic components and preferably a CPU. The electrical interface can also be arranged in the first installation space. Such an electrical interface can be designed to connect data lines or control lines or connect power lines. It can also be designed to connect data lines, control lines and power lines. The interface can be in the form of a plug or a socket. Components or component areas of the brake cover can also be arranged in the second installation space. Components or component areas of the brake dust collection device can also be arranged in the second installation space. Preferably, several of the above-mentioned components or assemblies can also be arranged at least partially in the second installation space. The advantage is that the second installation space is fully utilized. As a result, components for powerful brakes can also be positioned close to the floating caliper. This has a favorable effect on the bearing force (lever length is shortened). Overall, this also allows the necessary components to be accommodated in the area of ​​the rim and wheel mounting or wheel suspension.

[0015] Preferably, the above-mentioned brake cover or another brake cover is fastened to the floating caliper by means of the second fastening end. The brake cover can also be fastened to the second fastening end or to the second connecting part. The brake cover can also be fastened to both the second fastening end and the second connecting part. Preferably, the brake cover has a second retaining part, which is clamped between the second connecting part and the second fastening end. The second fastening end can include a screw, by which the second retaining part is fixed against the second connecting part. Preferably, the second retaining part has a channel, for this purpose, the screw passes through the channel. The effects of these fastening possibilities are the same as those already mentioned above with respect to fastening the brake cover to the first fastening end and the first connecting part or to fastening the first fastening end and the first connecting part together.

[0022] In a first embodiment of the floating caliper brake 1 according to the present invention, Figure 1 As shown, the floating caliper 40 is mounted so as to be displaceable in the axial direction A relative to the brake carrier 20 by means of a first guide assembly 8 and a second guide assembly 9. The floating caliper 40 has a finger region 42 and a piston region 41. In the connecting region between the finger region 42 and the piston region 41, the floating caliper 40 has a hollow portion on its inner side. The brake carrier 20 also has a cavity in this region. These cavities together form a chamber 4 for accommodating a brake disc. During operation of the floating caliper brake 1 and when the floating caliper brake 1 is installed in a motor vehicle, the brake disc can rotate in the chamber 4 about the axis of rotation 7.

[0023] In the present example, a side of the mounted brake disc in the mounted state which is oriented towards the finger area 42 or is located near the finger area 42 is defined as the second side 6. In the present example, a side of the mounted brake disc in the mounted state which is oriented towards the piston area 41 or is located near the piston area 41 is defined as the first side 5. The rotation axis 7 defines an axial direction A which extends along the rotation axis 7 or is parallel to the rotation axis 7. In the present example, a plane which extends in line with the rotation axis 7 is defined as the center plane 15. The center plane 15 separates the third side 10 from the fourth side 12.

[0024] Two mutually opposite brake pad units 3 are arranged in a chamber 4 so that the brake disc can rotate between them and the brake pad unit 3 can brake the brake disc when the floating caliper brake 1 is actuated. The actuating piston 2 is accommodated in the piston area 41 of the floating caliper 40, displaced in the axial direction A when the floating caliper brake 1 is actuated, and presses the brake pad unit 3 against the brake disc. For this purpose, the floating caliper 40 is mounted in an axially displaceable manner relative to the brake support 20. The actuating piston 2 is schematically shown with a dotted line. An electromechanical drive 60 is attached to the floating caliper 40 in the piston area 41. The electromechanical drive 60 includes a housing 63, a transmission 62 mounted in the housing 63, an electric motor 61 and an electrical interface 68 in the form of a socket. Depending on the application, the electrical interface 68 of the floating caliper brake 1 can be in the form of a socket or a plug. Only a part of the electric motor 61 can be seen. The floating caliper 40 has a first connecting portion 49 in the finger area 42 on the third side 10. The first connection portion 49 is fixedly connected to the floating caliper 40 , since it is the same cast part. The first connection portion 49 slightly protrudes from the floating caliper 40 away from the center plane 15 .

[0025] The first guide assembly 8 is located on the third side 10, spaced apart from the center plane 15 and comprises a first guide duct 21 which is made in a part of the brake carrier 20 and extends along the first guide axis 18 in the axial direction A between a first end 23 and a second end 24. The first guide duct 21 is closed at the first end 23 and is open at the second end 24. The first end 23 of the first guide duct 21 is located on the second side 6, i.e. at the level of the finger region 42 when viewed in the axial direction A, and the second end 24 is located on the first side 5, i.e. at the level of the piston region 41. The first guide assembly 8 further comprises a first guide element 43 having a first guide shaft 44 and a first fastening end 45. The first guide element 43 is fixedly connected to a first connecting portion 49 by its fastening end 45. A screw protrudes through the first connecting portion 49 and is screw-fastened to the first fastening end 45. The first guide element 43 is accommodated in the first guide duct 21 with its guide shaft 44 in a displaceably mounted manner. The open second end 24 of the first guide duct 21 is sealed by a schematically shown rubber sleeve, which is fastened to the second end 24 of the first guide duct 21 and the first guide element 43. The first installation space 11 is positioned aligned with the first guide axis 18, following the second end 24 of the first guide duct 21 when viewed from the second side towards the first side. The installation space is defined by the arrangement of the first connecting part 49 and the manner in which the first guide element 43 is fastened to the first connecting part 49 and introduced into the first guide duct 21. A part of an electromechanical drive 60 with a housing 63, an electric motor 61 and a transmission 62 is arranged in the first installation space 11. An electrical interface 68 is arranged in or near the first installation space 11.

[0026] The second guide assembly 9 is located on the fourth side 12, spaced apart from the center plane 15 and comprises a second guide duct 25 which is made in another part of the brake carrier 20 and extends along the second guide axis 19 in the axial direction A between a third end 27 and a fourth end 28. The second guide duct 25 is closed at the fourth end 28 and open at the third end 27. The fourth end 28 of the second guide duct 25 is located on the second side 6, i.e. at the level of the finger region 42 when viewed in the axial direction A, and the third end 27 is located on the first side 5, i.e. at the level of the piston region 41. The second guide assembly 9 further comprises a second guide element 46 having a second guide shaft 47 and a second fastening end 48. The second guide element 46 is fixedly connected to a second connecting portion 50 by its fastening end 48. This second connecting portion 50 is fixedly connected to the floating caliper 40 in the piston region 41 on the fourth side 12, since it is the same cast part. The second connecting portion 50 protrudes slightly from the floating caliper 40 away from the center plane 15 and the chamber 4. The screw protrudes through the second connecting part 50 and is screwed to the second fastening end 48. The second guide element 46 is accommodated in the second guide duct 25 with its guide shaft 47 in a displaceable manner. The open third end 27 of the second guide duct 25 is sealed by a schematically shown rubber sleeve, which is fastened to the third end 27 of the second guide duct 25 and the second guide element 46. Figure 1 In the view shown, the first connection part 49 and the second connection part 50 are arranged, to a certain extent, diagonally to each other. It can also be said that the two guide assemblies 8, 9 are arranged inverted relative to each other through a point at least in the direction in which the guide elements 43, 46 pass through the guide ducts 21, 25. In this example, the inversion point is located on the center plane 15 and in the area of ​​the chamber 4 or between the chamber 4 and the piston area 41. The first guide axis 18 and the second guide axis 19 are located in the same plane. The structure allows to obtain and optimize the installation space when the forces and moments are properly transmitted between the floating caliper 40 and the brake carrier 20. The parts of the transmission 62 and the associated housing 63 are arranged in the first installation space 11. These components are thereby arranged relatively close to the mounting of the floating caliper 40 in the axial direction, as a result of which the moments and forces in the mounting and the material stresses in the corresponding components are reduced.

[0027] Figure 2 The second embodiment of the floating caliper brake 1 according to the invention shown differs from the first embodiment only in the second guide assembly 9. For this reason, only these differences will be discussed below. In the case of the general structure of the floating caliper brake 1 and the first guide assembly 8, reference is made to the corresponding statements about the first embodiment.

[0028] In accordance with Figure 2In the second embodiment of the invention, the second guide assembly 9 is likewise located on the fourth side 12, spaced apart from the center plane 15 and comprises a second guide duct 25 which is made in another part of the brake carrier 20 and extends along the second guide axis 19 in the axial direction A between a third end 27 and a fourth end 28. The second guide duct 25 is open at the fourth end 28 and closed at the third end 27. The fourth end 28 of the second guide duct 25 is located on the second side 6, i.e. at the level of the finger region 42 when viewed in the axial direction A, and the third end 27 is located on the first side 5, i.e. at the level of the piston region 41. The second guide assembly 9 further comprises a second guide element 46 having a second guide shaft 47 and a second fastening end 48. The second guide element 46 is fixedly connected to a second connecting portion 50 by its fastening end 48. This second connecting portion 50 is fixedly connected to the floating caliper 40 on the fourth side 12 in the finger region 42, since it is the same cast part. The second connecting portion 50 protrudes slightly from the floating caliper 40 away from the center plane 15. The screw protrudes through the second connecting portion 50 and is screwed to the second fastening end 48. The second guide element 46 is accommodated in the second guide conduit 25 with its guide shaft 47 in a displaceable manner. The open fourth end 28 of the second guide conduit 25 is sealed by a rubber sleeve, which is fastened to the fourth end 28 of the second guide conduit 25 and the second guide element 46. Figure 2 In the view shown, the first connection part 49 and the second connection part 50 are arranged in a mirror-symmetrical manner relative to each other with respect to the center plane 15. The first guide axis 18 and the second guide axis 19 are located in the same plane. On the first side, on the third side and on the fourth side there are first and second installation spaces, which are aligned with the first guide axis 18 and the second guide axis 19 in the piston area, respectively. Due to the two installation spaces, components (e.g. cover plate, dust collector) can again be positioned close to the mounting (mounting of the floating caliper), as a result of which the installation space is optimized overall and the moments and forces in the mounting and the material stresses in the corresponding components are reduced.

[0029] exist Figure 3 In FIG. 1 , the electronic control unit 64 is schematically shown to be installed in the first installation space 11 by a rectangle. For the sake of clarity, Figure 3 Many reference numerals are omitted. Figure 2The corresponding reference numerals not shown can be found in . The electronic control unit 64 can include a CPU and a PCB with corresponding electronic components. It goes without saying that the electronic control unit 64 can also be installed in the second installation space 13, or it extends over the two installation spaces 11 and 13. The combination with the housing 63 in which the electronic control unit 64 is installed is particularly advantageous. During the energization of the floating caliper brake, especially in a powerful brake, a waterproof and dustproof housing is provided, which can also be used to accommodate the electrical control system and its components, which likewise leads to optimization of the installation space.

[0030] exist Figure 3 In the embodiment of the present invention, a brake cover 65 is also present on the second side 6. This brake cover 65 covers in particular the fingers of the floating caliper 40. The brake cover 65 has retaining portions 66, 67 on its outer ends extending away from the center plane 15. The first retaining portion 66 is fixed between a screw of the first fastening end 45 of the first guide element 43 and the first connecting portion 49 of the floating caliper 40. The second retaining portion 67 is fixed between a screw of the second fastening end 48 of the second guide element 46 and the second connecting portion 50 of the floating caliper 40. This type of fastening of the brake cover 65 is an advantageous design in terms of installation space.

[0031] Figure 3 The features of the invention shown in and described in the preceding paragraphs may of course also be used with Figure 1 The embodiments of the present invention shown in are combined and compatible.
