Description

Technical Field

[0001] The present disclosure relates to a brake assembly, such as a brake assembly for an automobile. Background Art

[0002] The brake assembly typically includes a brake group including one or more stator plates coupled to a stationary portion such as an axle housing, and one or more rotor plates coupled to a rotatable shaft to be braked. Typically, the brake assembly also includes a brake piston that can selectively compress the brake group to apply a braking torque on the rotor plate or on a rotatable shaft coupled to the rotor plate. The number of stator plates and / or rotor plates included in the brake group may vary depending on the maximum braking torque to be applied to the rotatable shaft and / or the available space for the brake group.

[0003] For example, it is advantageous that the brake assembly can be adapted to brake groups comprising different numbers of stator plates and / or rotor plates. In this way, the same brake assembly can be installed on vehicles of different sizes and / or different masses. In brake assemblies known in the prior art, changing the number of stator plates and / or rotor plates usually requires complex disassembly and reassembly procedures and / or changes to other components of the brake assembly. Utility Model Content

[0004] Therefore, there is a need for a brake assembly that is more easily adaptable to brake groups having different sizes.

[0005] The currently proposed brake components include:

[0006] a stationary portion forming a hollow portion for receiving the brake group therein, and

[0007] a stop member partially received or configured to be partially received in the hollow portion along the axis to form a brake group stop,

[0008] The stop member has a plurality of axially spaced coupling features for selectively coupling or securing the stop member to the stationary portion at any one of two or more different axial positions of the stop member relative to the stationary portion.

[0009] Since the coupling feature can couple or axially couple the stop member to the stationary part, e.g. at least along the axis, at any one of two or more different axial positions relative to the stationary part, the brake assembly can be easily adapted to brake groups having different axial thicknesses or axial extents. This can, for example, significantly reduce production costs and / or maintenance costs.

[0010] The stop member may be a sleeve-shaped member. The plurality of coupling features of the stop member may be arranged on a radially outer side of the stop member. The stop member may be coupled to the stationary part in a torque-proof manner relative to the axis, for example, by means of a plurality of radially extending protrusions of the stop member being received in an axially extending recess formed in a radially inner surface of the stationary part, wherein the radial direction is a direction perpendicular to the axis. The radially extending protrusions of the stop member may be axially spaced apart from the coupling features of the stop member. For example, at least one or more of the plurality of coupling features of the stop member may protrude out of a hollow portion of the stationary part.

[0011] The brake assembly may also include a brake group that is received in the hollow portion of the stationary part. Typically, the brake group includes one or more stator plates coupled to the stationary part, and one or more rotor plates configured to be coupled to the rotatable shaft. For example, the one or more stator plates may be coupled to the stationary part in a torque-proof manner, such as via a spline connection between the one or more stator plates and the stationary part, allowing the stator plates to move or slide along the axis relative to the stationary part. Similarly, the one or more rotor plates may be coupled to the rotatable shaft in a torque-proof manner, such as via a spline connection between the one or more rotor plates and the rotatable shaft, allowing the one or more rotor plates to move or slide along the axis relative to the rotatable shaft.

[0012] The brake assembly may also include a brake piston for selectively pressing the brake group against the stop member along the axis. Then, the brake group is usually arranged between the brake piston and the stop member along the axis.

[0013] The brake assembly may also include a coupling assembly secured to the stationary portion. Thus, the stop member may be configured to selectively couple to the coupling assembly via any one of a plurality of axially spaced coupling features. Or in other words, the stop member may be coupled to or secured to the stationary portion via the coupling assembly.

[0014] The coupling assembly may include a cover member secured to the stationary portion. For example, the brake assembly may include a plurality of fasteners securing the cover member to the stationary portion. The fasteners may include screws, bolts, etc. The coupling assembly may also include a coupling member mounted on the cover member. Thus, the stop member may be configured to selectively axially couple to or secure to the cover member via any of a plurality of axially spaced coupling features. The cover member may couple or secure the coupling member to the stationary portion. The coupling member may be mounted in a recess formed in a radially inner side of the cover member.

[0015] The plurality of axially spaced apart coupling features of the stop member may include a plurality of axially spaced apart annular grooves formed in the radial outer surface of the stop member. Thus, the coupling member may be selectively received in any one of the plurality of axially spaced apart annular grooves. For example, the coupling assembly may include a snap ring received in or configured to be received in any one of the plurality of axially spaced apart annular grooves of the stop member. For example, the coupling member of the coupling assembly may include or may be configured as the snap ring. In this way, the axial position of the stop member relative to the stationary part may be changed by engaging the snap ring with different ones of the axially spaced apart annular grooves of the stop member. For example, the plurality of axially spaced apart annular grooves may be periodically arranged along the axis. The period length of the plurality of axially spaced apart annular grooves may correspond to the sum of the axial thicknesses of one of the stator plates and one of the rotor plates.

[0016] Additionally or alternatively, the plurality of axially spaced apart coupling features of the stop member include a male threaded portion formed in a radially outer surface of the stop member. Thus, the coupling assembly may include a female threaded portion that engages with or is configured to engage with the male threaded portion of the stop member. For example, the female threaded portion may be formed in a radially inner surface of the coupling member. For example, the coupling member may be or may include a nut. In this way, the axial position of the stop member relative to the stationary portion may be changed by moving the threads of the female threaded portion of the coupling assembly or the coupling member along the threads of the male threaded portion of the stop member, or vice versa.

[0032] Figure 1a-1c A brake assembly 100 is schematically shown, comprising a stationary part 1 and a stop member 3. Figure 1b middle, Figure 1a The sectioning plane is indicated by the line labeled AA. Figure 1d A perspective view of the stop member 3 of the brake assembly 100 is depicted in FIG. Figure 1e-1g Schematically shows Figure 1a-1c A brake assembly 100 in which the stop member 3 is in different axial positions relative to the stationary part 1. Here and in the following, repeated features in different figures are indicated by the same reference numerals.

[0033] exist Figure 1a-1g In the brake assembly embodiment, the stationary part 1 has a cylindrical shape. One or both of the stationary part 1 and the stop member 3 may be rotationally symmetrical or substantially rotationally symmetrical with respect to the axis 4. The stationary part 1 forms a hollow portion 1a. The hollow portion 1a is open on one side along the axis 4, thereby allowing the stop member 3 to be inserted into the hollow portion 1a along the axis 4. The stop member 3 includes an annular stop portion 3a and a sleeve portion 3b extending from the stop portion 3a along the axis 4. The stop portion 3a and the sleeve portion 3b may be formed as one piece. The stop member 3 is partially received in the hollow portion 1a along the axis 4. More specifically, the stop portion 3a of the stop member 3 is received in the hollow portion 1a formed by the stationary part 1, while the sleeve portion 3b protrudes or at least partially protrudes from the hollow portion 1a along the axis 4.

[0034] In the embodiment of the brake assembly 100 depicted in the figures, the stationary part 1 is partially received in the axle housing 7. The stationary part 1 has a flange 1b that protrudes from the axle housing 7. The flange 1b extends radially outward and away from the axis 4, and abuts against a radially extending portion 7a of the axle housing 7. For example, the stationary part 1 can be fastened to the axle housing 7 by means of fasteners 8, see Figure 1b and 1c The fastener 8 may include screws, bolts, etc. For example, Figure 1b and 1c As indicated in , the fastener 8 may extend parallel to the axis 4 and pass through the flange 1 b of the stationary part 1 .

[0035] The brake assembly 100 further includes a brake group 2 disposed in the hollow portion 1a formed by the stationary part 1. The brake group 2 can be rotationally symmetrical with respect to the axis 4. The brake group 2 includes a plurality of stator plates 2a and a plurality of rotor plates 2b. The stator plates 2a and the rotor plates 2b extend perpendicularly to the axis 4 and are alternately stacked along the axis 4. The plates 2a, 2b each have an annular shape so that Figure 1b and 1c The rotatable shaft 10 shown in FIG. 1 may extend through the brake group 2 along an axis 4. The axis 4 coincides with the axis of rotation of the rotatable shaft 10. For reference purposes only, Figure 1a The rotatable shaft 10 is not shown.

[0036] The stator plates 2a are coupled to the stationary part 1 in a torque-proof manner relative to the axis 4. For example, the stator plates 2a may be coupled to the stationary part 1 via a spline connection. More specifically, each of the stator plates 2a may have a radial outer edge having a toothed profile that engages with an axially extending spline formed in a radial inner surface of the stationary part 1, wherein the radial outer edge of the stator plate 2a faces away from the axis 4 and the radial inner surface of the stationary part 1 faces the axis 4. In this way, the stator plate 2a may move or slide relative to the stationary part 1 along the axis 4.

[0037] Similarly, each of the rotor plates 2b may be coupled in a torque-proof manner to a rotatable shaft 10 extending through the brake group 2, for example via a spline connection. More specifically, each of the rotor plates 2b may have a radially inner edge having a toothed profile that engages with an axially extending spline formed in the outer surface of the rotatable shaft 10, wherein the radially inner edge of the rotor plate 2b faces the axis 4. In this way, the rotor plate 2b may move or slide on the rotatable shaft 10 along the axis 4.

[0038] The brake assembly 100 also includes a brake piston 5. Here, the brake piston 5 is arranged in a hollow portion 1a formed by the stationary part 1. Along the axis 4, the brake group 2 is arranged between the brake piston 5 and the stop member 3. The brake piston 5 is configured to move along the axis 4. The stop member 3, or more specifically, the stop portion 3a of the stop member 3 serves as a stop for the brake group 2. Or in other words, the stop portion 3a limits the brake group 2 from the brake piston 5 to move in the direction of the stop member 3 along the axis 4. That is, the brake piston 5 can push the brake group 2 against the stop member 3 along the axis 4, thereby compressing the plates 2a, 2b of the brake group 2 along the axis 4, thereby applying a braking torque on the rotor plate 2b and / or the rotatable shaft 10 to which the rotor plate 2b is connected. For example, the brake piston 5 can be configured to be actuated by hydraulic force or electromagnetic force. The shoulder portion 1c formed on the radial inner side of the stationary part 1 serves as another mechanical stop for the brake group 2. Or in other words, the shoulder portion 3 a limits the movement of the brake group 2 in a direction along the axis 4 from the stop member 3 toward the brake piston 5 .

[0039] like Figure 1a As can be seen in the figure, the axial position of the stop member 3 relative to the stationary part 1 determines the maximum axial thickness or maximum axial extent of the brake group 2. In addition, the axial position of the stop member 3 relative to the stationary part 1 determines the axial width of the gap 11 formed between the brake piston 5 and the brake group 2 when the brake piston 5 is in the non-braking or retracted position. For example, the axial width of the gap determines how fast and / or how hard the rotatable shaft 10 is braked when the operator actuates the brake piston 5, such as by stepping on the brake pedal.

[0040] The stop member 3 may be coupled to the stationary part 1 in a torque-proof manner relative to the axis 4. For example, the stop member 3 may comprise a plurality of protrusions 3c, see e.g. Figure 1d , which extend radially outwards from the stop portion 3a. The projections 3c can be received in correspondingly shaped axially extending recesses formed in the radially inner surface of the stationary part 1, which faces the axis 4.

[0041] Along the axis 4, the stop member 3 is axially coupled or secured to the stationary part 1 by means of a coupling assembly 6. In the embodiment of the brake assembly 100 depicted in the figure, the coupling assembly 6 comprises a cover member 6a and a coupling member 6c. The cover member 6a has an annular shape and is secured to the stationary part 1 via a plurality of fasteners 9. For example, the fasteners 9 may extend parallel to the axis 4 and pass through the cover member 6a. The fasteners 9 may include screws, bolts, etc.

[0042] In the embodiment of the brake assembly 100 shown in the figure, the coupling member 6c is a snap ring mounted on the cover member 6a. More specifically, the coupling member 6c is received in a recess 6b formed in the radial inner side or radial inner surface of the cover member 6a. For example, the coupling member 6c can be mounted on the cover member 6a or in the recess 6b formed by the cover member 6a in a press-fit manner. Figure 1a As shown, the recess 6b can be open along the axis 4 toward the brake group 2 or the brake piston 5. This can facilitate assembly because it can allow the cover member 6a to slide over the stop member 3 and the coupling member 6c after the coupling member 6c has been coupled to the stop member 3 or has been engaged with the stop member 3. In a radial direction perpendicular to the axis 4, the coupling member 6c protrudes from the recess 6b and faces the axis 4. Or in other words, the inner radius of the annular coupling member 6c is smaller than the minimum inner radius of the cover member 6a. The cover member 6a limits the movement of the coupling member 6c along the axis 4, for example, at least in the direction along the axis 4 from the brake piston 5 to the stop member 3.

[0043] In order to allow the axial position of the stop member 3 relative to the stationary part 1 to be suitable for various axial thicknesses of the brake group 2, the stop member 3 has a plurality of axially spaced coupling features, each of which can engage with the coupling member 6c. In the embodiment of the brake assembly 100 shown in the figure, the coupling feature includes three axially spaced annular grooves 30a-30c. The annular grooves 30a-30c are formed in the radial outer surface of the stop member 3. More specifically, the annular grooves 30a-30c are formed in the radial outer surface of the sleeve portion 3b of the stop member 3. Along the axis 4, the annular grooves 30a-30c are spaced apart from the stop portion 3a of the stop member 3 and the projection 3c extending from the stop portion 3a. The axial width of each of the annular grooves 30a-30c corresponds to or is slightly greater than the axial width of the coupling member 6c, so that the coupling member 6c can be received in each of the annular grooves 30a-30c. When the coupling member 6c is received in one of the annular grooves 30a-30c, the coupling member 6c is axially fixed relative to the stop member 3, and the cover member 6a limits the axial movement of the stop member 3 relative to the stationary part 1, for example at least in the direction from the brake piston 5 to the stop member 3 along the axis 4.

[0044] Figure 1e-1gIt is shown how the axial position of the stop member 3 relative to the stationary part 1 can be changed by engaging a coupling member 6c, given here as a snap ring, with different axially spaced annular grooves 30a-30c of the stop member 3, so that the axial position of the stop member 3 relative to the stationary part 1 is adapted to different thicknesses of the brake group 2. In particular, the axially spaced annular grooves 30a-30c of the stop member 3 are periodically arranged along the axis 4. The period length of the periodically arranged annular grooves 30a-30c corresponds to the sum of the axial thicknesses of one of the stator plates 2a and one of the rotor plates 2b.

[0045] exist Figure 1e In the embodiment, the brake group 2 comprises five stator plates and four rotor plates, the coupling member 6c is engaged with the leftmost annular groove 30a, and the stop member 3 is arranged in a first axial position relative to the stationary part 1. Figure 1f In the embodiment, the brake group 2 includes four stator plates and three rotor plates, that is, its axial thickness is Figure 1e The axial thickness of the brake group 2 is reduced, the coupling member 6c is engaged with the central annular groove 30b, and the stop member 3 is arranged at a second axial position relative to the stationary part 1, which is smaller than Figure 1e The first axial position of is further toward the brake piston 5. And Figure 1g In the embodiment, the brake group 2 includes three stator plates and two rotor plates, that is, its axial thickness is Figure 1f The axial thickness of the brake group 2 is reduced, the coupling member 6c is engaged with the rightmost annular groove 30c, and the stop member 3 is arranged at a third axial position relative to the stationary part 1, which is smaller than Figure 1f The second axial position of is further towards the brake piston 5 .

[0046] Figure 2a-2c A brake assembly 200 is schematically shown, comprising a stationary part 1 and a stop member 3. Figure 2b middle, Figure 2a The sectioning plane is indicated by the line labeled BB. Figure 2d A perspective view of the stop member 3 of the brake assembly 200 is depicted in FIG. Figure 2e-2g Schematically shows Figure 2a-2c The brake assembly 200 of the embodiment of the present invention is shown in Figure 1, wherein the stop member 3 is in different axial positions relative to the stationary part 1. As before, features that are repeated in different figures are indicated by the same reference numerals.

Unless otherwise expressly stated, Figure 2a-2g The brake assembly 200 may include Figures 1a-1g The brake assembly 100 has the same features.

That is, in FIG. Figure 2a-2g In the brake assembly 200, the axial position of the stop member 3 relative to the stationary part 1 can be changed by moving or twisting the threads of the female threaded portion 60 of the coupling member 6c along the threads of the male threaded portion 40 of the stop member 3, or vice versa.

[0049] In addition, Figure 2a-2g In the brake assembly 200 , the coupling member 6 c is disposed between the stationary part 1 and the cover member 6 b along the axis 4 , and the cover member 6 b fixes or secures the coupling member 6 c to the stationary part 1 .
