Description

Technical Field

[0001] This disclosure relates to a mounting assembly for securing components of a vehicle braking system to a vehicle structure.

[0002] Furthermore, this disclosure relates to a vehicle having such mounting components and a vehicle braking system. Background Technology

[0003] It is well known that components of a vehicle's braking system generate noise and vibration during operation. This is especially true for brake boosters.

[0004] Therefore, noise-absorbing devices are typically installed around the components of the vehicle's braking system, especially around the brake booster. These devices reduce noise and vibration without affecting the comfort of passengers inside the vehicle. In other words, the passenger compartment is isolated from the components of the vehicle's braking system in terms of noise and vibration.

[0005] However, absorption devices are expensive in terms of both material and labor costs because they need to be installed in vehicles. Summary of the Invention

[0006] Therefore, the purpose of this disclosure is to provide a solution for reducing noise and vibration generated during the operation of components of a vehicle braking system, which is cost-effective while maintaining a high level of effectiveness.

[0007] The problem is at least partially resolved or mitigated by the subject matter of the independent claims of this disclosure, wherein further examples are incorporated in the dependent claims.

[0008] According to a first aspect, a mounting assembly for securing components of a vehicle braking system to a vehicle structure is provided. The mounting assembly includes a mounting portion of the vehicle structure having a through-hole and a mounting element of the vehicle braking system having a through-hole. A bolt extends through the through-hole of the mounting portion and the through-hole of the mounting element. The bolt has a bolt head at its first end. Furthermore, a nut engages the bolt at its second end portion opposite the first end, wherein the mounting portion is attached to the mounting element via the bolt and nut. Additionally, a resilient bushing is provided having a bushing body disposed in the through-hole of the mounting portion or the through-hole of the mounting element. The resilient bushing also has a first bushing collar extending radially from the bushing body. The first bushing collar extends on a first axial side corresponding to the mounting portion or the mounting element. In this context, the corresponding mounting portion or mounting element is a mounting portion or mounting element having a through-hole in which the bushing body of the resilient bushing is disposed. The first axial side is defined relative to the central axis of the through-hole in which the bushing body is disposed. The first bushing collar can, for example, be inserted between the mounting portion and the mounting element. Because the bushing is elastic, it provides attenuation or damping in terms of noise and vibration. This is especially true for the first bushing collar. When placed between the mounting portion and the mounting element, noise and vibration are prevented from being transmitted between these elements. Furthermore, bushings are readily available on the market at a relatively low cost. This is particularly true when considering the typically large-scale production in the automotive industry. Additionally, bushings are easy to install when mounting components of a vehicle braking system. Therefore, the mounting assembly according to this disclosure provides a cost-effective solution for suppressing noise and / or vibration.

[0009] The resilient bushing may have a second bushing collar extending radially from the bushing body, the second bushing collar being disposed at the end of the bushing body opposite to the end where the first bushing collar is disposed. In other words, the bushing has bushing collars at both ends. This means that if the bushing is disposed in a through-hole of the mounting portion, the resilient bushing collars are disposed on both sides of the mounting portion. If the bushing is disposed in a through-hole of the mounting element, the resilient bushing collars are disposed on both sides of the mounting element. In both cases, this results in effective attenuation of noise and vibration generated by the operation of components of the vehicle braking system.

[0010] The second ring can be positioned between the nut and the mounting portion or element along the axial direction of the elastic bushing. As a result of this configuration, noise and / or vibration can only be transmitted to the nut and its mating bolts in a damped manner. This further prevents noise and vibration from reaching the passenger compartment.

[0011] The bolt can extend through the resilient bushing. In other words, the bushing circumferentially surrounds the bolt. This is especially true for the bushing body. This configuration is very compact. Therefore, the mounting assembly is suitable for installation in the constrained space of a vehicle.

[0012] Flexible bushings can be a single, integral structure. In other words, flexible bushings can be designed as a single piece. This simplifies bushing design. Furthermore, such bushings can be easily installed within mounting components.

[0013] Furthermore, the mounting assembly may include a rigid bushing having a bushing body extending through a through-hole identical to the through-hole through which the resilient bushing passes. The rigid bushing has a radially projecting bushing collar disposed at the axial end of the bushing body. The bushing collar of the rigid bushing is disposed outside the resilient bushing. This rigid bushing can be used to compress the resilient bushing in a defined and at least locally substantially uniform manner. This allows the damping characteristics of the resilient bushing to be set. Furthermore, vibrations can be fed into the resilient bushing for damping via the rigid bushing.

[0014] Bolts can also extend through the rigid bushing. Again, this configuration is very compact. Furthermore, bolts can be used to compress the resilient bushing in a defined manner via the rigid bushing.

[0015] The collar of a rigid bushing can be inserted between the nut and the flexible bushing. Therefore, the rigid bushing occupies very limited space.

[0016] The end of the rigid bushing opposite to its collar can abut against a mounting portion or mounting element. Therefore, the rigid bushing can be easily positioned in a defined location. Thus, the mounting portion or mounting element against which the bushing abuts serves to position the rigid bushing. Of course, the rigid bushing positioned in a defined location can also be used to position other components of the mounting assembly.

[0017] The mounting assembly may additionally include a stop member with a through-hole through which the bolt extends. The stop member abuts against a nut and has at least one abutting leg configured to abut against a mounting portion or mounting element. Thus, the stop member is secured within the mounting assembly by bolts and nuts. The abutting leg can be used to limit the relative movement of the components of the mounting assembly relative to each other.

[0018] In the neutral state of the mounting assembly, a gap can be provided between one end of the adjacent leg and the mounting portion or mounting element. In this context, the neutral state of the mounting assembly should be understood as a state in which the components of the vehicle braking system neither generate noise nor vibration. This means that the deformation of the elastic bushing will not exceed the deformation that occurs due to its installation within the mounting assembly. Therefore, this gap defines the range of motion within the mounting assembly available for further elastic deformation of the elastic bushing. More precisely, this gap defines the range of relative motion between the mounting portion and the mounting element.

[0019] Furthermore, damping material can be arranged in the adjacent area of ​​the mounting portion or mounting element, which is configured to contact the adjacent leg. Therefore, noise and / or vibration are particularly avoided when the adjacent leg contacts the adjacent area. This further improves the comfort of vehicle passengers.

[0020] In this variant, the stop member can be formed as part of the rigid bushing. In other words, the stop member and the rigid bushing are implemented as a single component. This makes the design of the mounting assembly very simple. Furthermore, since only one component needs to be installed—that is, the component that is both the stop member and the rigid bushing—instead of two components, namely the stop member and the rigid bushing, the assembly of the mounting assembly becomes easy.

[0021] An extension space may be provided radially adjacent to the first and / or second bushing rings of the elastic bushing on the mounting portion and / or mounting element, such that the first and / or second bushing rings can extend into the extension space upon deformation. Therefore, the elastic bushing can freely deform into the extension space. In other words, the deformation of the elastic bushing is not hindered by geometric constraints. Consequently, vibration and noise can be reliably reduced.

[0022] According to a second aspect, a vehicle is provided that includes a mounting assembly and a vehicle braking system according to the present disclosure. Components of the vehicle braking system are fixed to the vehicle structure via the mounting assembly. Therefore, noise and vibration generated by the operation of the components of the vehicle braking system are effectively reduced in a cost-effective manner.

[0023] In one example, a component of the vehicle braking system is a brake booster.

[0024] It should be noted that, regardless of the aspects involved, the above examples can be combined with each other.

[0025] These and other aspects of this disclosure will become apparent and illustrated with reference to the examples described below. Attached Figure Description

[0026] Examples of this disclosure will now be described with reference to the following figures:

[0031] Figure 5 It shows the corresponding Figure 3 The view includes the installation components according to the second example of this disclosure, and

[0032] Figure 6 It shows along Figure 5 A sectional view of plane VI-VI in the diagram.

[0033] The accompanying drawings are merely illustrative and are intended to illustrate examples of this disclosure only. In principle, identical or equivalent elements have the same reference numerals. Detailed Implementation

[0034] Figure 1 A vehicle 10 with a vehicle braking system 12 is shown, which is illustrated schematically.

[0035] The vehicle braking system 12 includes a pedal unit 14 that extends into the passenger compartment 16 of the vehicle 10.

[0036] In addition, the vehicle braking system 12 has a component 18 that serves as a brake booster and is operatively connected to the pedal unit 14.

[0037] For ease of explanation, components of the vehicle braking system and brake boosters are indicated by reference numeral 18 in the attached drawing.

[0038] In addition, an exemplary front brake caliper 20 adapted to interact with the front brake disc 22 is connected to the brake booster 18 via an exemplary first brake line 24.

[0039] An exemplary rear brake caliper 26 is adapted to interact with a rear brake disc 28. The rear brake caliper 26 is connected to the brake booster 18 via an exemplary second brake line 30.

[0040] The brake booster 18 is secured to the structure 31 of the vehicle 10 via mounting assembly 32. More precisely, the brake booster 18 is secured to the partition wall 34 that separates the motor compartment 36 from the passenger compartment 16. This partition wall 34 is sometimes referred to as a firewall. Clearly, the partition wall 34 forms part of the structure 31 of the vehicle 10.

[0041] exist Figure 2 The brake booster 18 and pedal unit 14 are shown in more detail. The partition wall 34 is also visible. In addition, a front bulkhead bracket 38, which is also fixed to the partition wall 34, is shown.

[0042] Now refer to Figure 3 and 4 A first example of mounting assembly 32 is illustrated. In these figures, the brake booster 18 is not shown to enhance the visibility of the components of mounting assembly 32.

[0043] Mounting assembly 32 includes mounting portion 40 of vehicle structure 31. In this example, mounting portion 40 is a plate-shaped portion of partition wall 34.

[0044] Mounting portion 40 has through hole 42 (see...) Figure 4 ).

[0045] In addition, mounting assembly 32 includes mounting element 44 for vehicle braking system 12. In this example, mounting element 44 is a generally plate-shaped mounting element 44 for brake booster 18.

[0046] Mounting element 44 also has through hole 46.

[0047] In addition, bolts 48 are provided that extend through the two through holes 42 and 46.

[0048] Bolt 48 has a bolt head 50 at its first end.

[0049] In this example, the bolt head 50 abuts against the mounting portion 40 on the side opposite to the mounting element 44.

[0050] At the second end portion of the bolt 48, which is positioned opposite the first end, the nut 52 is screwed onto the bolt 48. This means that the external thread of the bolt 48 engages with the internal thread of the nut 50.

[0051] In addition, a flexible bushing 54 is provided.

[0052] The resilient bushing 54 has a bushing body 56 extending through a through-hole 46 of the mounting element 44.

[0053] More precisely, the bushing body 56 radially abuts against the cylindrical surface of the circumference forming the through hole 46.

[0054] The resilient bushing 54 has a first bushing collar 58 extending radially from the bushing body 56.

[0055] The first bushing collar 58 abuts against the edge of the through hole 46. Furthermore, the first bushing collar 58 is located between the mounting portion 40 and the mounting element 44.

[0056] The resilient bushing 54 also has a second bushing collar 60 extending radially from the bushing body 56.

[0057] Compared to the first bushing collar 58, the second bushing collar 60 is located at the opposite end of the bushing body 56.

[0058] The second bushing collar 60 also abuts against the edge of the through hole 46. However, the edge abutting the second bushing collar 60 is located on the opposite side compared to the edge abutting the first bushing collar 58.

[0059] In addition, the second bushing collar 60 is located between the nut 52 and the mounting element 44 along the axial direction A of the elastic bushing 54, which corresponds to the axial direction of the through holes 42 and 46.

[0060] The elastic bushing 54, namely the bushing body 56, the first bushing collar 58, and the second bushing collar 60, are formed as one unit.

[0061] Mounting assembly 32 also includes a rigid bushing 62.

[0062] The rigid bushing 62 also has a bushing body 64.

[0063] The bushing body 64 extends radially inside the elastic bushing 54 through the through hole 46 of the mounting element 44.

[0064] In addition, the rigid bushing 62 has a radially protruding bushing collar 66, which is disposed at the end of the bushing body 64.

[0065] The bushing collar 66 of the rigid bushing 62 is axially arranged outside the second bushing collar 60 of the elastic bushing 54.

[0066] The bushing collar 66 abuts axially against the second bushing collar 60.

[0067] Therefore, the bushing collar 66 of the rigid bushing 62 is located between the nut 52 and the elastic bushing 54 (more precisely, its second bushing collar 60).

[0068] Furthermore, the rigid bushing 62 is arranged within the mounting assembly 32 such that the end 68 of the rigid bushing 62 opposite to the bushing collar 66 abuts against the mounting portion 40.

[0069] Bolt 48 extends through the center of rigid bushing 62.

[0070] Since the rigid bushing 62 is at least partially radially arranged within the elastic bushing 54, the bolt 48 also extends through the elastic bushing 54.

[0071] Mounting assembly 32 also includes a stop member 70, which is typically shaped as a half-shell and has a through hole 72 through which bolts 48 extend.

[0072] On the first side, the stop member 70 abuts against the nut 52.

[0073] On the opposite second side, the stop member 70 abuts against the bushing collar 66 of the rigid bushing 62.

[0074] Therefore, the central portion of the stop member 70 is located between the nut 52 and the rigid bushing 62.

[0075] The stop member also has an adjacent leg 74, which is configured to abut against the mounting element 44.

[0076] In this example, when the central axis A of the through hole 72 is taken as the center, the adjacent leg has a generally circular shape. However, the axial length of the adjacent leg 74 is different from its perimeter.

[0077] To provide a defined range of motion for the mounting element 44, a gap 76 is provided between one end of the adjacent leg 74 and the adjacent region 78 of the mounting element 44. Of course, this is only... Figure 3 and Figure 4 The installation component 32 shown is in a neutral state.

[0078] To soften the potential contact between the adjacent leg 74 and the mounting element 44, damping material 80 is disposed on the adjacent area 78.

[0079] Therefore, the mounting part 40 is attached to the mounting element 44 by bolts 48, elastic bushing 54, rigid bushing 62, stop member 70 and nut 52.

[0080] Thus, the rigid bushing 62 and the stop member 70 are rigidly fixed to the mounting portion 40 by bolts 48 and nuts 52. This is because the end 68 of the rigid bushing 62 rigidly abuts against the mounting portion 40, and the stop member 70 is rigidly held against the rigid bushing 62 by nuts 52.

[0081] Furthermore, if the rigid bushing 62 is mounted on the mounting portion 40 such that the end 68 of the rigid bushing abuts against the mounting portion 40, the resilient bushing 54 is compressed in a defined manner. Therefore, the axial space available for the resilient bushing 54 in the mounted state corresponds to the distance between the end 68 of the rigid bushing 62 and its bushing collar 66.

[0082] However, by compressing the first bushing collar 58, the mounting element 44 can move relative to the mounting portion 40 in the first axial direction.

[0083] Furthermore, by physically compressing the second bushing cover 60, the mounting element 44 can move relative to the mounting portion 40 in the second axial direction. However, the range of movement in the second axial direction is limited by the size of the gap 76. Once the gap 76 is overcome, the mounting element 44 abuts against the stop member 70.

[0084] Furthermore, the mounting element 44 can move in the radial direction by deforming the bushing body 56.

[0085] In order not to geometrically restrict the elastic deformation of the elastic bushing 54, the extension space 82 is arranged radially adjacent to the first bushing collar 58, so that the latter can extend into the extension space 82 during deformation.

[0086] In this example, the extension space 82 is a geometric feature of the mounting element 44.

[0087] During the operation of the brake booster 18, this movement of the mounting element 44 will be generated as part of the vibration. Due to the aforementioned deformation of the elastic bushing 54, these vibrations will not be transmitted to the mounting portion 40, or at least will be attenuated before being transmitted to the mounting portion 40.

[0088] Now refer to Figure 5 and 6 A second example of mounting assembly 32 is illustrated. Similarly, in these figures, the brake booster 18 is not shown to enhance the visibility of the components of mounting assembly 32.

[0089] The only difference between the mounting assembly 32 of the second example and the mounting assembly 32 of the first example is that the stop member 70 is formed as part of the rigid bushing 62. In other words, the stop member 70 and the rigid bushing 62 are formed as a single component.

[0090] In the second example, it can be imagined that the stop 70 and its adjacent leg 74 are formed by extending the bushing 66 of the rigid bushing 62.

[0091] In addition, refer to the explanation given in the first example.

[0092] Note that in both the first and second examples, the mounting element 44 is not only mounted on the mounting portion 40 via bolts 48 and nuts 52 as previously explained. In both examples, a second bolt 84 and a second nut 86 are provided.

[0093] However, in both examples, the mounting element 44 is secured to the mounting portion 40 via the second bolt 84 and the second nut 86, in the same manner as the securing method via bolt 48 and nut 52. Therefore, the description above can be referenced.

[0094] in other words, Figure 4 and 6 The illustration also shows the fastening via the corresponding second bolt 84 and the corresponding second nut 86.

[0095] It should also be understood that the mounting assembly 32 described above can be kinematically reversed without departing from the basic idea of ​​this disclosure. This means that the resilient bushing 54 and the rigid bushing 62 can also be arranged in the through hole 42 of the mounting portion 40, and the bolt head 50 can abut against the mounting element 44.

[0096] Based on an examination of the drawings, the disclosure, and the appended claims, those skilled in the art can understand and implement other variations of the disclosed examples in practice with respect to the claimed disclosure. In the claims, the word "comprising" does not exclude other elements or steps, and the indefinite articles "a" or "an" do not exclude a plurality. No reference numerals in the claims should be construed as limiting the scope of the claims.
