[0006] The axle braking module according to the present invention, having the constituent elements of claim 1, is characterized in that the axle braking module has one common hydraulic brake circuit, or two hydraulic brake circuits attached to each of the wheel braking mechanisms, each as a hydraulically closed brake circuit, such that the brake circuit is attached only to the axle braking module. With the configuration of the axle braking module according to the present invention, each corresponding axle of the automobile is attached to a separate, independent brake circuit. The axle braking module does not require external hydraulic coupling. When multiple axle braking modules are provided, in particular when one axle braking module is provided for each axle of the automobile, these are electrically coupled to a higher-level control logic in particular for activation, and are not hydraulically coupled to one another. From this, the advantage is obtained that the braking system is configured modularly and can be pre-installed independently of the assembly of the automobile. In particular, the usual filling of a vehicle-wide hydraulic brake circuit, which can only be done after the braking system has been completely assembled, is omitted. This is because the axle braking module is a hydraulically closed system and is therefore advantageously pre-filled. To this extent, the axle braking module is an advantageous alternative to the already known axle braking module described at the beginning. While the already known axle braking module does have at least one unique brake force generator per axle, it is clear that each brake force generator is not part of a separate hydraulically closed brake circuit, and in particular relies on a single common brake fluid reservoir.

[0007] According to an advantageous further configuration of the present invention, the brake force generator comprises a activatable first actuator and a first hydraulic piston connected to the actuator and displaceable within a brake cylinder, wherein the first piston chamber, closed by the first hydraulic piston, is fluid-technically connectable to a hydraulic brake circuit or a first hydraulic brake circuit among a plurality of hydraulic brake circuits. The use of this type of actuator with a hydraulic piston provides the advantageous possibility of reliably supplying hydraulic fluid to the corresponding hydraulic brake circuit of the axle braking module. In this case, the brake cylinder is formed as a single main brake cylinder.

[0008] Particularly advantageous is that the brake force generator has a second hydraulic piston that is spring-elastically connected to a first hydraulic piston and displaceable within the brake cylinder, and the second piston chamber closed by the second hydraulic piston is fluid-technically connectable to a second hydraulic brake circuit among a plurality of hydraulic brake circuits, and each of the plurality of hydraulic brake circuits is attached to the other wheel braking mechanism among a plurality of wheel braking mechanisms. By using two hydraulic pistons connected in this way, the advantage is obtained that each of the plurality of wheel braking mechanisms can be attached to one unique hydraulic piston. In this case, the brake cylinder is formed as a tandem type main brake cylinder.

[0009] According to an advantageous further configuration of the present invention, the axle braking module has one hydraulic pump or one hydraulic pump in each hydraulic brake circuit, in which case the hydraulic pump or one of several hydraulic pumps is attached to the wheel braking mechanism. By using and attaching hydraulic pumps or each hydraulic pump, the advantageous possibility is provided to supply hydraulic fluid to each wheel braking mechanism as needed.

[0010] Particularly advantageous, the axle braking module has at least one activatable second actuator, which is attached to each hydraulic pump or to multiple hydraulic pumps in common. The second actuator provides the advantageous possibility of precisely operating the hydraulic pumps or each hydraulic pump to control the fluid flow.

[0011] According to an advantageous further configuration of the present invention, the axle braking module has a plurality of suction valves and a plurality of discharge valves in the hydraulic brake circuit, or in each hydraulic brake circuit, in which case each wheel braking mechanism is equipped with one suction valve from the plurality of suction valves and one discharge valve from the plurality of discharge valves. The suction valves and discharge valves provide the advantageous possibility of precisely controlling the hydraulic pressure in each wheel braking mechanism.

[0012] Particularly advantageous is that the hydraulic pump, or each hydraulic pump, can be fluid-technically coupled to the respective wheel braking mechanism at the inlet side by its respective discharge valve. The coupling of the hydraulic pump at the inlet side provides the advantageous possibility of reducing the hydraulic pressure as needed, particularly easily, by activating the hydraulic pump.

[0013] According to an advantageous further configuration of the present invention, the axle braking module has one main switching valve or one main switching valve in each hydraulic brake circuit, in which case each piston chamber is fitted with one main switching valve or each main switching valve, and the hydraulic pump is fluidly coupled to / coupled to each piston chamber at the inlet side by the main switching valve or each main switching valve. The main switching valve provides the advantageous possibility of reliably disconnecting or coupling the piston chamber from the brake circuit.

[0014] A braking system for an automobile or vehicle trailer having the constituent elements of claim 9 is characterized by being provided with a first axle braking module formed according to the present invention, which can be attached to / is attached to one axle of the automobile or vehicle trailer, particularly the first axle. From this, the advantages already described are obtained.

[0015] Particularly advantageous is that the braking system has a second axle braking module formed according to the present invention, which can be attached to / is attached to another axle of the automobile or vehicle trailer, particularly a second axle, and has a configuration different from that of the first axle braking module. By using at least one second axle braking module, the advantage is obtained that the braking system is modularly configured from at least two hydraulic modules per axle.

[0016] According to an advantageous further configuration of the present invention, the braking system has two electromechanical wheel braking modules, each equipped with one activatable actuator for generating braking force, which are particularly identically configured and can be attached to / attached to other wheels on another axle of the automobile or vehicle trailer, particularly on a second or third axle. The use of two wheel braking modules is advantageous because it ensures that the braking system is configured as a hybrid consisting of at least one hydraulic (wet) module and two electromechanical (dry) modules.

[0017] Particularly advantageous is that the braking system has at least one control mechanism specifically designed to activate the axle braking module or all braking modules, especially the axle braking module and / or wheel braking modules, in a coordinated manner. This type of control mechanism provides the advantage that the braking system as a whole is activated robustly. As mentioned above, if there are multiple modules, the control mechanism serves to activate these modules in a coordinated manner as a whole.

[0018] An automobile having the constituent features of claim 13 is characterized by having the braking device according to the present invention. From this, the advantages already described can also be obtained. In particular, the automobile is part of a vehicle outfit having at least one vehicle trailer. The vehicle trailer, in particular, has at least one further axle braking module according to the present invention.

[0019] A vehicle trailer having the constituent features of claim 14 is characterized by having the braking device according to the present invention. From this, the advantages already described can also be obtained.

[0020] Further advantageous constituent features and combinations of constituent features are apparent from the foregoing description and the claims. Hereinafter, the present invention will be described in more detail with reference to the drawings.

Brief Description of the Drawings

[0021] [Figure 1] It is a figure which shows the 1st Example of an advantageous axle braking module. [Figure 2] It is a figure which shows the 2nd Example of an axle braking module. [Figure 3] It is a figure which shows the 3rd Example of an axle braking module. [Figure 4] It is a figure which shows the 4th Example of an axle braking module. [Figure 5] It is a figure which shows an automobile or a vehicle trailer provided with at least one of a plurality of axle braking modules.

Modes for Carrying Out the Invention

[0022] Figs. 1 to 4 show different examples of the advantageous axle braking module 1, respectively. Fig. 1 shows the first example of the axle braking module 1, Fig. 2 shows the second example, Fig. 3 shows the third example, and Fig. 4 shows the fourth example.

[0023] In the following, as far as possible and meaningful, the same reference numerals are assigned to similar components and they are described together. The differences are pointed out at appropriate places. The axle brake module 1 is a component of the brake device 2 of the motor vehicle 3 or the vehicle trailer 4, respectively.

[0024] For this reason, FIG. 5 illustrates an embodiment of the motor vehicle 3 or the vehicle trailer 4, in which case the motor vehicle 3 or the vehicle trailer 4 has the brake device 2, a first axle 5, for example, a front axle, and a second axle 6, for example, a rear axle. However, the embodiment with two axles 5, 6 is only an example, and in particular, only one axle may be provided (in the case of a vehicle trailer), or a large number of axles, for example, an additional third axle may be provided (possible in the case of the motor vehicle 3 and the vehicle trailer 4). Each axle 5, 6 has two wheels 7.

[0025] The axle brake module 1 has, respectively, an operable first wheel brake mechanism 8 and an operable second wheel brake mechanism 9 for decelerating the motor vehicle 3 or the vehicle trailer 4. The wheel brake mechanisms 8, 9 are formed as normal hydraulically operable friction brakes in this embodiment, and for this purpose have at least two friction partners, particularly a brake lining and a brake disc. One of the friction partners, for example, the brake lining, is supported so as to be displaceable in the direction of the other friction partner, for example, in the direction of the brake disc.

[0026] Each of the wheel brake mechanisms 8, 9 can be attached to the other wheel among a plurality of wheels 7 of the same axle 5, 6 of the motor vehicle 3 or the vehicle trailer 4, or, as suggested in FIG. 5, is attached.

[0027] The feature of each axle brake module 1 is that it has only the two wheel brake mechanisms 8, 9, and further that the axle brake module 1 is formed as a hydraulic closed system, that is, it does not have a hydraulic connection to other wheel brake mechanisms.

[0028] Therefore, each axle braking module 1 further has, in this embodiment, exactly one activatable brake force generator 10. The brake force generator 10 is formed to generate brake pressure in each wheel braking mechanism 8, 9 by transporting hydraulic fluid into at least one hydraulic brake circuit. In this embodiment, there is no mechanical intervention, for example, using a brake pedal that can be operated by a driver. Such intervention is provided according to other embodiments not shown.

[0029] In Figures 1 and 2, the axle braking module 1 has a single hydraulic brake circuit 11 that is attached to both wheel braking mechanisms 8 and 9 in common. The hydraulic brake circuit 11 is configured to be attached only to the axle braking module 1 as a hydraulically closed brake circuit.

[0030] In Figures 3 and 4, the axle braking module 1 includes a first hydraulic brake circuit 11 attached to the first wheel braking mechanism 8 and a second hydraulic brake circuit 12 attached to the second wheel braking mechanism 9. Each of the hydraulic brake circuits 11 and 12 is formed as a hydraulically closed brake circuit and is attached only to the axle braking module 1.

[0031] In Figures 1 to 4, the brake force generator 10 includes, respectively, a activatable first actuator 13 and a first hydraulic piston 14 connected to the actuator 13. In this embodiment, the actuator 13 is formed as an electromechanical unit and is connected to the hydraulic piston 14, for example, via a transmission device not shown in detail.

[0032] The actuator 13 is equipped with a rotor position sensor 26 for determining the rotor position of the rotor shaft of the electromachine. The hydraulic piston 14 is displaceable within the brake cylinder 15 and is pre-biased on one side by spring elasticity within the brake cylinder 15.

[0033] The first piston chamber 16, which is closed by the first hydraulic piston 14 inside the brake cylinder 15, is fluid-technically connectable to, or connected to, the first hydraulic brake circuit 11. In the figure, the corresponding connections are indicated by connecting joints S1.

[0034] In Figures 3 and 4, the brake force generator 10 additionally includes a second hydraulic piston 17 which is spring-elastically connected to the first hydraulic piston 14. The second hydraulic piston 17 is similarly displaceable within the brake cylinder 15 and is pre-biased spring-elastically on both sides within the brake cylinder 15.

[0035] The second piston chamber 18, which is closed by the second hydraulic piston 17, is fluid-technically connectable to, or connected to, the second hydraulic brake circuit 12. In the figure, the corresponding connections are indicated by connecting couplings S2.

[0036] Each axle braking module 1 further has a reservoir 19 for hydraulic fluid. The reservoir 19 has at least one first chamber 20 and, in Figures 3 and 4, an additional second chamber 21, in which case the second chamber 21 is fluid-technically isolated from the first chamber 20, particularly at least in part, by, for example, a partition.

[0037] Each reservoir 19 is fluid-technically coupled to, or is coupled to, each piston chamber 16, 18 via at least one hydraulic tube 22, 23. In this embodiment, each hydraulic tube 22, 23 contains one check valve 24, 25.

[0038] Specifically, the first piston chamber 16 is connectable to / connected to the first chamber 20 by a first hydraulic pipe 22 equipped with a first check valve 24, and in Figures 3 and 4, the second piston chamber 18 is connectable to / connected to the second chamber 21 by a second hydraulic pipe 23 equipped with a second check valve 25.

[0039] Furthermore, the axle braking module 1 has a first hydraulic pump 27 in the first hydraulic brake circuit 11, and in Figures 2 to 4, it has an additional second hydraulic pump 28 in the first hydraulic brake circuit 11 (Figure 2) or in the second hydraulic brake circuit 12 (Figures 3 and 4).

[0040] In Figure 1, the first hydraulic pump 27 is commonly attached to the wheel braking mechanisms 8 and 9 in a corresponding manner, while in Figures 2 to 4, the first hydraulic pump 27 is attached to the first wheel braking mechanism 8, and the second hydraulic pump 28 is attached to the second wheel braking mechanism 9, respectively.

[0041] In this configuration, the axle braking module 1 has at least one activatable second actuator 29, which is attached to the first hydraulic pump 27 (Figure 1) or is attached in common to the first and second hydraulic pumps 27,28 (Figures 2 to 4). In this embodiment, the actuator 29 is formed as an electromechanical device and is connected to the hydraulic pumps 27,28 via a transmission device, for example, not shown in detail. In particular, the respective pump wheels of each hydraulic pump 27,28 are coupled to the rotor shaft of the machine so as not to rotate relative to it.

[0042] Furthermore, each axle braking module 1 has two suction valves 30, 31 and two discharge valves 32, 33. In this embodiment, each of the suction valves 30, 31 is fitted with check valves 34, 35 that are hydraulically connected in parallel thereto. Each of the hydraulic brake circuits 11, 12 contains at least one of the suction valves 30, 31 and at least one of the discharge valves 32, 33.

[0043] Each of the wheel braking mechanisms 8 and 9 is precisely equipped with one of the suction valves 30 and 31 and one of the discharge valves 32 and 33. The first wheel braking mechanism 8 is equipped with one first suction valve 30 with one first check valve 34 and one first discharge valve 32, and the second wheel braking mechanism 9 is equipped with one second suction valve 31 with one second check valve 35 and one second discharge valve 33.

[0044] The first suction valve 30, equipped with a first check valve 34, and the first discharge valve 32 are each located within the first hydraulic brake circuit 11. The second suction valve 31, equipped with a second check valve 35, and the second discharge valve 33 are correspondingly located either within the first hydraulic brake circuit 11 (Figures 1 and 2) or within the second hydraulic brake circuit 12 (Figures 3 and 4).

[0045] The hydraulic pumps 27 and 28 are used as reverse pumps to return excess hydraulic fluid back to their respective piston chambers 16 and 18, and finally into their respective chambers 20 and 21 in the reservoir 19, in order to correct the hydraulic brake pressure, for example, after the completion of one braking process.

[0046] Therefore, the hydraulic pumps 27 and 28, or each of the hydraulic pumps 27 and 28, can be fluid-technically coupled to, or are coupled to, their respective wheel braking mechanisms 8 and 9 by their respective discharge valves 32 and 33 at the inlet side.

[0047] In addition, to form further receiving chambers for hydraulic fluid as needed, a cylinder 36, 37 is further positioned between the inlet side of each hydraulic pump 27, 28 and the respective discharge valves 32, 33, each equipped with a displaceable and spring-biased piston 38, 39. Specifically, a first cylinder 36 with a first piston 38 is positioned on the inlet side of the first hydraulic pump 27, and in Figures 2 to 4, a second cylinder 37 with a second piston 39 is positioned on the inlet side of the second hydraulic pump 28.

[0048] In Figure 2, additional check valves 40 and 41 are positioned between the inlet sides of each cylinder 36 and 37 and each hydraulic pump 27 and 28. Specifically, a second check valve 40 is positioned between the first cylinder 36 and the first hydraulic pump 27, and a third check valve 41 is positioned between the second cylinder 37 and the second hydraulic pump 28.

[0049] Each of the hydraulic pumps 27 and 28 is also fitted with a separate check valve 42 and 43 at its outlet. Specifically, a third check valve 42 is located at the outlet of the first hydraulic pump 27, and a fourth check valve 43 is located at the outlet of the second hydraulic pump 28.

[0050] In addition, within the first hydraulic brake circuit 11 in Figure 2, a pressure sensor 44 is further positioned upstream of each hydraulic pump 27, 28 and check valve 42, 43. In Figure 2, the axle braking module 1 further includes first and second main switching valves 45, 46 and first and second switching valves 47, 48 within the hydraulic brake circuit 11. The main switching valves 45, 46 and the switching valves 47, 48 are attached to the piston chamber 16.

[0051] The first hydraulic pump 27 is fluid-technically coupled to, or is coupled to, the piston chamber 16 on the inlet side by a first main switching valve 45 located between the hydraulic pump 27 and another first check valve 40. The second hydraulic pump 28 is fluid-technically coupled to, or is coupled to, the piston chamber 16 on the inlet side by a second main switching valve 46 located between the hydraulic pump 28 and another second check valve 41.

[0052] The first hydraulic pump 27 and the first suction valve 30 are fluid-technically coupled to the piston chamber 16 at the outlet side by the first switching valve 46, or are coupled to it. The second hydraulic pump 28 and the second suction valve 31 are fluid-technically coupled to the piston chamber 16 at the outlet side by the second switching valve 48, or are coupled to it.

[0053] In Figure 4, the configuration of the first hydraulic brake circuit 11 corresponds to that in Figure 3. In contrast, the configuration of the second hydraulic brake circuit 12 has several features. Specifically, the arrangement of the second hydraulic pump 28 has been changed as follows: the second hydraulic pump is equipped with both a second suction valve 31 with a second check valve 35 and a second discharge valve 33 on its outlet side. As a result, the second hydraulic pump 28 can be selectively coupled to the second piston chamber 18 by one of the valves on its outlet side, or is already coupled to it.

[0054] A check valve 49 is positioned between the second piston chamber 18, the second piston 37, and the second discharge valve 33, and a pressure sensor 44 is positioned between the check valve 49 and the second piston chamber 18, which corresponds to Figure 2.

[0055] In summary, the axle braking module 1 shown in Figure 1 realizes a one-channel anti-lock braking system (ABS), the axle braking module 1 shown in Figure 2 realizes an additional stability control system (ESP), the axle braking module 1 shown in Figure 3 realizes a two-channel anti-lock braking system (ABS), and the axle braking module 1 shown in Figure 4 realizes hybrid ABS / ESP functionality with a favorably reduced number of components.

[0056] Finally, as suggested at the beginning, Figure 5 schematically illustrates an automobile 3 or vehicle trailer 4. The braking system 2 built inside has at least one of the aforementioned axle braking modules 1 shown in Figures 1 to 4 on at least one of the axles 5 and 6.

[0057] The axle braking module 1 is a component of a modular system advantageous for the braking device 2 due to its hydraulically closed configuration and the fact that it is limited to exactly one axle. Thus, the braking device 2 has a first axle braking module attached to, for example, the first axle 5 of the axle braking module 1.

[0058] Additionally, the braking device 2 includes, as indicated by the dashed boxes, a second axle braking module attached to the second axle 6 of the axle braking module 1, or two electromechanical wheel braking modules 50 attached to one of each of the wheels 7 of the second axle 6.

[0059] These axle braking modules 1 may be identically formed or differently formed. The wheel braking modules 50 may similarly be identically formed or differently formed, and each has one activatable actuator for generating braking force.

[0060] In order to consistently activate the corresponding braking modules 1, 50, the braking device 2 further includes at least one control mechanism 51 that is or is communicately coupled to each of the braking modules 1, 50. [Explanation of Symbols]
