Description

[0001] The invention relates to a brake arrangement for a commercial vehicle, comprising an axle element for supporting a wheel hub whose axis of rotation coincides with the longitudinal center axis of the axle element, a brake comprising both axle-fixed elements and elements rotatable with the wheel hub, wherein a component of the axle-fixed elements is a brake carrier which transmits the braking forces to the axle element and is mounted on a fastening section of the axle element. For radial mounting on the axle element, the brake carrier has a fork section with a first and a second leg, on which inner surfaces facing one another are formed, wherein the axle element is provided with a first contact surface for contacting the inner surface of the first leg and with a second contact surface facing away from the first contact surface for contacting the inner surface of the second leg.

[0002] A brake assembly of the type mentioned above is known from DE 10 2006 002 442 A1. The brake assembly comprises a disc brake for a wheel of a vehicle. An axle assembly has an outer contour that deviates from a circular shape in cross-section. The brake carrier has an opening whose inner contour deviates from the circular shape and rests against the outer contour of the axle assembly in such a way that the brake carrier is positively coupled to the axle assembly in the circumferential direction around the axis of the brake. A screw arranged transversely to the axis of the brake is provided for temporarily fixing the brake carrier to the axle assembly. The brake carrier is welded to the axle assembly for permanent fixation.

[0003] The aim of the invention is to create a modular brake assembly for a commercial vehicle suitable for transmitting high braking torques. This assembly offers the possibility of combining completely different brake anchors with one and the same axle element, even at a late stage of axle assembly and even during final assembly, depending on the requirements and intended use, thus achieving maximum freedom in the assembly process. In particular, the assembly of the brake anchor should be possible for both a commercial vehicle brake assembly with single tires and a commercial vehicle brake assembly with dual tires. These differ essentially in the offset of 0 and 120.

[0004] The intended modular design should, in particular, offer the possibility of attaching either the brake carrier of a drum brake or the brake carrier of a disc brake to the axle element, thus shifting the decision about whether to use a drum-braked or disc-braked commercial vehicle axle to a later point in the manufacturing and assembly process. Despite the desired flexibility, the brake arrangement should be capable of transmitting high braking torques. Furthermore, it should also be possible to swap the brake carrier of a drum brake for a disc brake.

[0005] To solve this problem, a brake arrangement for a commercial vehicle with the features of patent claim 1 is proposed. Advantageous embodiments of the brake arrangement are specified in subclaims 2 to 15.

[0006] According to the invention, each of the two legs of the fork section on the brake carrier is provided with a bore which is arranged coaxially - to the hole in the other leg, - to a bore in the axle element, which extends radially from the respective contact surface to the longitudinal center axis.

[0007] Furthermore, at least one connecting element extends simultaneously through the bore of the leg and the bore in the axle element. In particular, a single connecting element is provided that extends simultaneously through the respective bore of the respective leg and the bore in the axle element.

[0008] In other words, the brake carrier is pushed radially onto the axle element, with the fork section between the two legs receiving the axle element. The inner surfaces of the legs come into contact with the contact surfaces of the axle element, with the radial fixation of axle element and brake carrier taking place via at least one connecting element which extends at least through the bore in the leg and the bore in the axle element. The respective bore in the leg can at least partially have a thread for fastening purposes. Preferably, the respective bore in the leg is cylindrical and threadless. In particular, at least one of the two bores in the leg is designed as a through bore, with the other bore in the respective leg being designed as a blind bore.Preferably, at least one of the two bores on the respective leg has a thread intended to interact with a thread on the connecting element. Preferably, the bore formed as a blind hole has an internal thread.

[0009] In the present case, a connecting element is understood to be an essentially cylindrical component, in particular a screw element, bolt or pin. Preferably, a single connecting element is provided, wherein the respective bore on the leg and the respective bore on the axle element accommodate the connecting element. In particular, a bore on the axle element is designed as a blind hole. Preferably, at least one bore on the axle element has at least partially a thread. Thus, the brake carrier is connected to the axle element in a rotationally and preferably axially fixed manner by the positive connection on the axle element, wherein the connecting element is provided for a detachable radial connection between the brake carrier and the axle element. The inner surfaces of the legs and the contact surfaces of the axle element are provided for the positive connection between the brake carrier and the axle element.Preferably, the surface normals of the two contact surfaces extend in directions 180° opposite.

[0010] The brake assembly is particularly well-suited for a modular manufacturing process and offers a high degree of flexibility, even during the final assembly of a commercial vehicle axle. Different brake types and sizes can be combined with one and the same axle element. The modular design allows for the choice of detachably mounting either a drum brake or a disc brake on the prepared axle element during final assembly. Due to the detachable connection between the brake anchor plate and the axle element, it is also possible to swap the brake anchor plate of a drum brake for a disc brake.

[0011] The achieved flexibility does not compromise the ability to transmit high braking torques from the brake carrier to the axle element. Rather, the inner surfaces of the arms and the contact surfaces of the axle element provide the prerequisite for transmitting high braking forces and braking torques to the axle element of the vehicle axle. The force transmission is such that the connecting elements that secure the brake carrier to the axle element are largely relieved of braking forces and braking torques. Instead, the braking torques emanating from the brake carrier are transmitted primarily in a tangential direction, and thus in the direction of the actually acting forces, via the inner surfaces of the arms to the contact surfaces on the axle element.

[0012] Preferably, the bores in the axle element are each longitudinal sections of a through bore extending between the first contact surface and the second contact surface. Thus, the bore in the first contact surface is connected to the bore in the second contact surface, so that the two bores form the through bore. This provides the advantage of using only a single connecting element to connect the brake carrier and axle element. Furthermore, two connecting elements can also be used to connect the brake carrier and axle element.

[0013] According to a preferred embodiment, the brake carrier is formed in two parts, consisting of the fork section and a counter element detachably connected thereto. When the brake carrier is mounted on the axle element, the fork section and counter element at least mutually contact one another. When mounted on the axle element, the counter element, together with the fork section, preferably completely encloses the axle element.

[0014] The axle element preferably has a third and a fourth contact surface for the fork section of the brake carrier, wherein a bore extends radially from the respective contact surface to the longitudinal center axis. The third contact surface is designed to be identical to the first contact surface, but is axially offset on the axle element. Furthermore, the fourth contact surface is designed to be identical to the second contact surface, but is axially offset on the axle element. The brake carrier can be mounted on the first and second contact surface or alternatively on the third and fourth contact surface, depending on the application. If the brake carrier is mounted on the first and second contact surface, the third and fourth contact surface and thus also the bores formed therein remain unused. If the brake carrier is mounted on the third and fourth contact surface, the first and second contact surface and thus also the bores formed therein remain unused.

[0015] In particular, a respective closure element is provided to be arranged in a respective unused bore on the respective contact surface of the axle element in order to prevent the penetration of contaminants into the respective unused bore. The closure element is preferably made of a polymer material. The closure element is preferably designed as a sealing element. In particular, the closure element is at least partially cylindrical and is provided to be inserted with a distal end into the respective bore in order to close it. Alternatively, at least one sleeve is provided to be spatially arranged between the two legs in the bores of the axle element in order to prevent the penetration of contaminants into the respective unused bore on the leg.For this purpose, the at least one sleeve is arranged coaxially with the unused bore on the leg and rests on the end face between the two legs. Preferably, a single sleeve is arranged between the two legs in the bores of the axle element. Alternatively, two sleeves are arranged between the two legs in the bores of the axle element.

[0016] The invention includes the technical teaching that the counter element has a first and a second bore, which are arranged coaxially with a third and fourth bore on the fork section and accommodate a respective connecting element for releasably connecting the counter element and the fork section. Thus, one connecting element extends through the first bore on the counter element into the third bore on the fork section, while the other connecting element extends through the second bore on the counter element into the fourth bore on the fork section. The two connecting elements releasably connect the counter element and the fork section to one another, thereby forming the two-part brake carrier.

[0017] According to a first embodiment, the respective bore on the counter element is arranged substantially parallel to the longitudinal center axis of the axle element. According to a second embodiment, the respective bore on the counter element is arranged tangentially with respect to the longitudinal center axis of the axle element. In other words, according to the second embodiment, the respective bore on the counter element extends transversely to the longitudinal center axis of the axle element.

[0018] Preferably, the counter element has a first and a second leg, wherein the first leg of the counter element is connected to the first leg of the fork section, and the second leg of the counter element is connected to the second leg of the fork section. In particular, the two legs enclose an acute angle. Alternatively, the two legs enclose a right angle or a straight angle.

[0019] Preferably, the two legs of the counter element are integrally connected to one another via a bridge section, wherein a radial free space is located between an inner side of the bridge section facing the axle element and the axle element. In other words, the two legs are arranged on the bridge section of the counter element, wherein the bridge section connects the two legs to one another and thereby forms the counter element. When the counter element is mounted on the fork section, the radial free space is formed between the inner side of the bridge section and the axle element. In particular, the counter element only comes into contact with the fork section. Preferably, only the legs of the counter element come into contact with the legs of the fork section.

[0020] Furthermore, the two legs of the fork section are preferably connected to one another in one piece via a bridge section, wherein a radial clearance is located between an inner side of the bridge section facing the axle element and the axle element. When the fork section is mounted on the axle element, the radial clearance is formed between the inner side of the fork section and the axle element.

[0021] In the brake arrangement according to the invention, in the case of the drum brake design, one or two bearing pins are formed on the fork section for pivotably supporting two brake shoes of the drum brake. Preferably, a pivot bearing is formed on the counter element for rotatably supporting a shaft bearing a cam element, wherein the cam element is provided to spread the two brake shoes of the drum brake during braking. In particular, the cam element is formed at a distal end of the shaft, wherein a drive section is formed at the second distal end of the shaft, and wherein the cam element, the shaft, and the drive section are preferably connected to one another in one piece to form a brake camshaft.

[0022] In the brake arrangement according to the invention, in the case of the disc brake design, the brake carrier is formed in one piece and is intended to receive at least one brake pad of the disc brake on a section facing away from the fork section.

[0023] In the following, exemplary embodiments of the invention are explained with reference to the drawings, and further details and advantages are given. They show: Fig. 1 shows a perspective view of a first exemplary embodiment of a fully assembled brake arrangement for a commercial vehicle, which serves to connect a drum brake to an axle element of a commercial vehicle axle; Fig. 2 shows a perspective view of a second exemplary embodiment of a fully assembled brake arrangement for a commercial vehicle, which serves to connect a drum brake to an axle element of a commercial vehicle axle; Fig. 3 the items according to Fig. 1 before assembly; Fig. 4 the items according to Fig. 2 before assembly; Fig. 5 the items according to Fig. 1 in a side view; Fig. 6 a sectional view according to a Fig. 5 shown cutting line; Fig. 7 the items according to Fig. 2 in a side view; Fig. 8 a sectional view according to a Fig. 7 shown cutting line; Fig. 9 shows a perspective view of a third exemplary embodiment of a fully assembled brake assembly for a commercial vehicle, which serves to connect a disc brake to an axle element of a commercial vehicle axle; and Fig. 10 the items according to Fig. 9 in a side view.

[0024] The brake arrangement described here is used on the vehicle axle of a commercial vehicle and preferably on a rigid vehicle axle with an elongated axle body which is provided at both ends with steering knuckles for supporting the wheel hubs and the wheels of the vehicle.

[0025] The commercial vehicle axle is also equipped with a vehicle brake in the area of each wheel hub. The vehicle brake can be either a drum brake, in which two brake shoes mounted on an axle-fixed brake carrier are spread outward at their other ends against the brake drum, or a disc brake, in which two brake pads are pressed against a brake disc arranged between them and rotating with the wheel hub. The actual actuation mechanism for the drum or disc brake is arbitrary; however, for heavy commercial vehicle axles, pneumatic actuation of the brake is common, using a compressed air cylinder attached to an axle element 1 or to the disc brake caliper.

[0026] It is common practice to adapt the technical design of a commercial vehicle axle in advance to the respective brake type (drum or disc brake), and vice versa. It is then practically impossible to choose a different brake type or even a different brake size after axle element 1 has been completed, as the connections would then not match.

[0027] The brake arrangement described below allows for much greater flexibility. In particular, the flexibility is so great that even during final assembly, when the axle element 1 is already fully produced, the most suitable brake for the respective application can be decided upon and then installed. This is achieved by a modular design of the axle element 1 of the vehicle axle, on the one hand, and the brake carrier 40, on the other hand, which in turn can be either the brake carrier 40 of a drum brake ( Fig. 1 to Fig. 8), or the brake carrier 40 ( Fig. 9 and Fig. 10) a disc brake.

[0028] In general, the brake carrier 40 is the element of a drum or disc brake that is fixed to the axle. Depending on their respective mode of operation, drum brakes and disc brakes are also equipped with rotating parts that rotate with the wheel hub, for example, the brake drum in the case of a drum brake, and the brake disc in the case of a disc brake.

[0029] According to Fig. 1 to Fig. 10, the vehicle axle, designed as a rigid axle, consists of an axle tube (not shown here) with a round or square cross-section, to whose two ends the axle elements 1 are attached, whereby only one of the two identical axle elements 1 is shown in each figure. Components of each axle element 1 are a fastening section 4 and a steering knuckle 2, on which the vehicle's wheel hub and the brake drum or brake disc are rotatably mounted by means of corresponding rolling bearings. Located between the steering knuckle 2 and the axle tube, on the same longitudinal center axis A, is the fastening section 4. This serves to connect the axle-fixed elements of the brake.

[0030] In Fig. 1, Fig. 3, Fig. 5 and Fig. 6 shows a first embodiment of the brake arrangement according to the invention. Fig. 2, Fig. 4, Fig. 7 and Fig. 8 show a second embodiment of the brake arrangement according to the invention. Furthermore, Fig. 9 and Fig. 10 a third embodiment of the brake arrangement according to the invention.

[0031] According to Fig. 1 to Fig. 8, the brake arrangement comprises the axle element 1 for supporting the wheel hub, the axis of rotation of which coincides with the longitudinal center axis A of the axle element 1, a drum brake (not shown here) comprising both axle-fixed elements and elements rotatable with the wheel hub, wherein a component of the axle-fixed elements is a brake carrier 40 which transmits the braking forces to the axle element 1 and is mounted on a fastening section 4 of the axle element 1.

[0032] The brake carrier 40 has a fork section 12 with a first and a second leg 6A, 6B and is mounted radially to the longitudinal center axis A on the axle element 1. Inner surfaces facing each other are formed on the legs 6A, 6B. Furthermore, the axle element 1 has a first contact surface 7A for contacting the inner surface of the first leg 6A, and a second contact surface 7B facing away from the first contact surface 7A for contacting the inner surface of the second leg 6B. In the present case, the first contact surface 7A is formed substantially parallel to the second contact surface 7B. Alternatively, it is also conceivable to form the two contact surfaces 7A, 7B at a slight angle.

[0033] Each of the two legs 6A, 6B is provided with a bore 26.1, 26.2, which is arranged coaxially to the bore 26.2, 26.1 in the other leg 6B, 6A, and coaxially to a bore 27.1, 27.2 in the axle element 1, which extends radially from the respective contact surface 7A, 7B to the longitudinal center axis A. Furthermore, a connecting element 36.1 is guided through the respective bore 26.1, 26.2 of the respective leg 6A, 6B and the bores 27.1, 27.2 in the axle element 1. Furthermore, a sleeve 36.2 is guided through the bores 27.1, 27.2 in the axle element 1. The connecting element 36.1 is bolt-shaped and extends through the sleeve 36.2. The sleeve 36.2 is arranged between the two legs 6A, 6B and prevents dirt from entering the holes 26.1, 26.2 on the respective leg 6A, 6B. Both holes 26.2, 26.1 in the respective leg 6B, 6A are designed as through holes, wherein the hole 26.2 in the second leg 6B has a thread 25 for screwing in the connecting element 36.1, wherein the connecting element 36.1 also has a thread at its distal end section.

[0034] The axle element 1 has a third and a fourth contact surface 7C, 7D for the fork section 12 of the brake carrier 40, wherein a bore 27.3, 27.4 extends radially from the respective contact surface 7C, 7D to the longitudinal center axis A. The axial position of the brake carrier 40 on the axle element 1 can thus be varied between the contact surfaces 7C, 7D and 7A, 7B. The contact surfaces 7C, 7D are identical to the contact surfaces 7A, 7B, but are arranged axially offset from one another on the axle element 1. The contact surfaces 7A, 7B, like the contact surfaces 7C, 7D, are essentially parallel to one another. Furthermore, the contact surfaces 7A, 7C are located in a common plane. The contact surfaces 7B, 7D are also located in a common plane.

[0035] As is particularly evident from Fig. 6 and Fig. 8, the bores 27.1, 27.2 in the axle element 1 are each longitudinal sections of a through bore which extends between the first contact surface 7A and the second contact surface 7B.

[0036] The brake carrier 40 is formed in two parts from the fork section 12 and a counter element 3 detachably connected thereto. The counter element 3, together with the fork section 12, completely encloses the axle element 1. Furthermore, the counter element 3 has a first and a second bore 28.1, 28.2, which are arranged coaxially with a third and fourth bore 29.1, 29.2 on the fork section 12 and accommodate a respective connecting element 37.1, 37.2 for detachably connecting the counter element 3 and the fork section 12. In the present case, the bores 28.1, 28.2 are designed as through bores without a thread, with the bores 29.1, 29.2 having a thread. The two connecting elements 37.1, 37.2 are designed as screw elements.

[0037] The counter element 3 has a first and second leg 8A, 8B, wherein the first leg 8A of the counter element 3 is connected to the first leg 6A of the fork section 12, and the second leg 8B of the counter element 3 is connected to the second leg 6B of the fork section 12. The two legs 8A, 8B of the counter element 3 are integrally connected to one another via a bridge section 58, wherein a radial clearance is located between an inner side 59 of the bridge section 58 facing the axle element 1 and the axle element 1. Furthermore, the two legs 6A, 6B of the fork section 12 are integrally connected to one another via a bridge section 48, wherein a radial clearance is located between an inner side 49 of the bridge section 48 facing the axle element 1 and the axle element 1.

[0038] As is particularly evident from Fig. 3, a form-fitting contour is formed on the legs 8A, 8B of the counter element 3 and on the legs 6A, 6B of the fork section 12, wherein the form-fitting contours are essentially complementary to one another and position the fork section 12 and the counter element 3 relative to one another.

[0039] According to Fig. 1, Fig. 3, Fig. 5 and Fig. 6, the respective bore 28.1, 28.2 on the counter element 3 is arranged essentially parallel to the longitudinal center axis A of the axle element 1. According to Fig. 2, Fig. 4, Fig. 7 and Fig. 8, the respective bore 28.1, 28.2 on the counter element 3 is arranged tangentially with respect to the longitudinal center axis A of the axle element 1.

[0040] Two bearing pins 43 for pivotably supporting two brake shoes of the drum brake are formed on the fork section 12. Furthermore, a pivot bearing 51 is formed on the counter element 3 for rotatably supporting a shaft (not shown here) carrying a cam element. The cam element is designed to spread the two brake shoes of the drum brake during braking.

[0041] According to Fig. 9 and Fig. 10, the brake arrangement comprises the axle element 1 for supporting the wheel hub, the axis of rotation of which coincides with the longitudinal center axis A of the axle element 1, a disc brake (not shown here) comprising both axle-fixed elements and elements rotatable with the wheel hub, wherein a component of the axle-fixed elements is a brake carrier 40 which transmits the braking forces to the axle element 1 and is mounted on a fastening section 4 of the axle element 1.

[0042] The brake carrier 40 has a fork section 12 with a first and a second leg 6A, 6B and is mounted radially to the longitudinal center axis A on the axle element 1. Inner surfaces facing one another are formed on the legs 6A, 6B. Furthermore, the axle element 1 has a first contact surface 7A for contacting the inner surface of the first leg 6A, and a second contact surface facing away from the first contact surface 7A for contacting the inner surface of the second leg 6B, the second contact surface not being shown here. The first contact surface 7A is formed substantially parallel to the second contact surface. Alternatively, it is also conceivable to form the two contact surfaces at a slight angle.

[0043] Each of the two legs 6A, 6B is provided with a bore 26.1, 26.2, which is arranged coaxially to the bore 26.2, 26.1 in the other leg 6B, 6A, and coaxially to a bore 27.1, 27.2 in the axle element 1, which extends radially from the respective contact surface 7A to the longitudinal center axis A. Furthermore, a single connecting element 36.1 is guided simultaneously through the bores 26.1, 26.2 of the respective leg 6A, 6B, which are arranged on a common axis, and the bore 27.1, 27.2 in the axle element 1. The bores 27.1, 27.2 in the axle element 1 and the bore 26.2 in the leg 6B are not shown.

[0044] The axle element 1 also has a third contact surface 7C and a fourth contact surface 7D (not visible here), wherein the two contact surfaces 7C, 7D face away from each other and are formed substantially parallel to each other. A bore 27.3 extends radially from the contact surface 7C toward the longitudinal center axis A. The bore 27.3 is arranged on a common axis with another bore that extends radially from the contact surface 7D toward the longitudinal center axis A. The axial position of the brake anchor plate 40 on the axle element 1 can be varied between the contact surfaces 7C and 7A depending on the offset for single or double tires on the commercial vehicle axle. In the present case, a closure element 5 is arranged in the unused bore 27.3 to prevent dirt from penetrating the unused bore 27.3.

[0045] The brake carrier 40 is formed in one piece and is intended to receive a brake pad of the disc brake (not shown here) on a section 9 facing away from the fork section 12. In the present case, the brake carrier 40 is designed to be particularly weight-optimized, with rod structures being formed in the brake carrier 40 to transfer the load of a braking torque indicated by the arrow F. The brake carrier 40 is therefore designed like a truss. First and second kidney-shaped recesses 13A, 13B are formed spatially between the rod structures. The dashed line D illustrates the course of the compressive forces derived from the braking torque F. Furthermore, the dashed line Z illustrates the course of the tensile forces derived from the braking torque F. The tensile and compressive forces Z, F are introduced into the two contact surfaces of the brake carrier 40 on the axle element 1.The two kidney-shaped recesses 13A, 13B face each other with their two narrow, tapered ends. In other words, the two kidney-shaped recesses 13A, 13B are wider and thus larger toward the respective legs 6A, 6B. This geometric design of the kidney-shaped recesses 13A, 13B promotes an arcuate distribution of the tensile and compressive forces Z, D in the brake carrier 40.
