Abstract
Description
Technical Field
[0001] This disclosure relates to a bushing for a joint assembly for a vehicle suspension, a joint assembly for a vehicle suspension, and a vehicle suspension. Background Technology
[0002] A tight and sealed connection is crucial to preventing hydrogen embrittlement of the high-strength screws used in the joint. This is especially important in suspension screw joints and dynamic high-load joints in vehicle suspensions. This is because water entering the interior of such joints can cause corrosion. Even small corrosion damage on the screw surface can potentially lead to sudden screw breakage. Consequently, the threaded joint will no longer function, which will limit the vehicle suspension's capabilities and could potentially make driving a vehicle with such a suspension system dangerous. Summary of the Invention
[0003] According to a first aspect, a bushing for a joint assembly in a vehicle suspension is provided. The bushing includes an inner cylinder portion for receiving a pivot element of the joint assembly. The inner cylinder portion includes a longitudinal extension along a longitudinal axis and two end faces located at opposite longitudinal ends of the inner cylinder portion. The bushing also includes an outer cylinder portion surrounding the inner cylinder portion. Furthermore, the bushing includes an elastic portion disposed between the inner cylinder portion and the outer cylinder portion. At least one of the longitudinal ends of the inner cylinder portion includes a protruding section extending in height along the longitudinal axis, protruding in height beyond one of the end faces, and extending circumferentially in length around the longitudinal axis.
[0004] In bushings used in joint assemblies of vehicle suspensions, the outer cylinder portion is subjected to shear forces from rotating components of the vehicle suspension (e.g., swivel arms). Advantageously, a protruding section can increase the shear load capacity of the entire joint assembly, or in other words, increase the shear load capacity of the joint itself, with little or no dependence on friction. This is because the protruding section extends beyond its end face by a certain height or extends above its end face, thereby allowing it to clamp or cut into the U-shaped clamping side of the U-shaped clamp of the joint assembly in which the bushing is used. Thus, the protruding section creates the appearance function of a U-shaped clamp, thereby increasing the shear load capacity of the entire joint assembly. In addition, the protruding section extends circumferentially about the longitudinal axis of the inner cylinder portion or generally the bushing, or in other words, extends longitudinally, extending its maximum extension in any dimension. Therefore, this locking function can advantageously be provided along the entire circumference of the longitudinal axis, for example, along most or substantially the entire outer periphery of the end face, thereby significantly increasing the shear load capacity of the joint assembly. In addition, the locking function helps to secure and seal the connector assembly, preventing water from entering between the pivot element and the inner cylinder, thereby effectively reducing or preventing corrosion.
[0005] Typically, a bushing may include a cylindrical shape and consist of several portions that may also be cylindrical or other shapes. These portions are referred to herein as an inner cylinder portion, an outer cylinder portion, and an elastic portion. These portions may generally be cylindrical in shape, and the bushing may or may not be limited to these cylindrical portions. For example, the bushing may include a metallic material. Specifically, the inner and outer cylinder portions may include or be made of metallic material, while the elastic portion may include or be made of an elastic material (e.g., an elastomer). Specifically, the elastic portion may be sandwiched between or otherwise arranged between the inner and outer cylinder portions.
[0006] The inner cylinder portion may have a cylindrical shape with an opening or channel. The opening or channel may extend from one end face at one longitudinal end of the inner cylinder portion to another end face at its opposite longitudinal end. The opening or channel may be located in the middle of the inner cylinder portion and extend along its longitudinal axis, which is the axis along which the inner cylinder portion extends, its length being its maximum extension in one dimension. Pivoting elements, such as screws, shafts, pins, or similar elements, may be received through or within the opening or channel. The longitudinal axis may be a rotationally symmetric axis for the inner cylinder portion, outer cylinder portion, and / or elastic portion. The inner diameter of the opening or channel may be substantially equal to or greater than the outer diameter of the pivoting element. The end face at the opposite longitudinal end of the inner cylinder portion may be a substantially flat surface, except for a protruding section projecting above it, and particularly projecting from or extending from it, but not limited to this.
[0007] The outer cylinder portion may have a cylindrical shape with an opening or channel. This opening or channel may be significantly larger than the opening or channel of the inner cylinder portion, allowing the inner cylinder portion and the elastic portion to be received within them. Specifically, the outer cylinder portion may surround (particularly substantially completely surround) the elastic portion, and the elastic portion may (particularly substantially completely surround) surround the inner cylinder portion. The outer cylinder portion may include one or more attachment devices or segments for attachment to rotating components of the vehicle suspension.
[0008] A resilient section can provide elasticity to the joint assembly within the bushing. The resilient section can typically be derived from an elastic material or otherwise possess elastic properties, such as being formed as a mechanical spring or the like. At its longitudinal end, the resilient section can be U-shaped, or in other words, recessed. The U-shape or recess can be arranged along the longitudinal axis. Thus, the resilient section can provide (further) elastic properties. However, this could potentially allow water or an inlet to enter the space between the pivot element and the inner cylinder, which could potentially lead to corrosion. This can be prevented, in particular, by a protruding section and optionally by another protruding section on the resilient section as further described herein.
[0009] According to one example, the protruding section can be formed as a protruding ring on one of the end faces. As a ring, the protruding section can be substantially entirely or completely circumferential around the longitudinal axis and extend on one of the end faces. The protruding ring may have one or more interruptions along its extension, such as recesses, or no interruptions at all. The protruding ring can, in particular, be continuous. This means that the protruding ring has no interruptions like recesses. Specifically, this may mean maintaining a minimum height above the end face along the longitudinal extension of the protruding ring. In particular, the height above the end face along the longitudinal extension of the protruding ring can be a substantially constant height. The protruding ring further enhances the locking function of the protruding section, thereby increasing the shear load capacity and watertight seal of the joint assembly.
[0010] According to one example, the protruding section may extend lengthwise along the outer periphery of the inner cylinder. Specifically, the protruding section may extend lengthwise, or in other words, longitudinally, along the outer periphery or outermost periphery of the inner cylinder on its end face. Therefore, a locking function of the protruding section can be provided at the outer periphery or outermost periphery of the inner cylinder. Specifically, this could be where an optional additional protruding section of the elastic portion can be provided and extend lengthwise together with the protruding section.
[0011] According to one example, the protruding section can be configured as a sealing section for abutting against a U-clamp sealing bushing in the connector assembly. Thus, the protruding section is constructed to provide a sealing function against the U-clamp. For example, the protruding section can be a geometry as defined herein, such as having a pointed peak or end, such that it cuts into or clamps into the U-clamp, thereby establishing a seal against the U-clamp.
[0012] According to one example, at least one of the two opposite longitudinal ends of the elastic portion may include another protruding section, which extends in height along the longitudinal axis, protruding beyond one of the end faces in height, and extends circumferentially around the longitudinal axis in length. The other protruding section may comprise or be made of an elastic material, particularly the same elastic material used in the elastic portion. Specifically, the other protruding section may be an elastic protruding section. In particular, the other protruding section may be formed as a sealing lip. In particular, the other protruding section may be formed as a sealing ring or annular sealing lip that can extend circumferentially around the longitudinal axis in length. As a ring, the other protruding section may extend substantially entirely or completely around the circumference of the longitudinal axis. The other protruding ring may, in particular, be uninterrupted along its extension, for example, by a recess. The other protruding ring may, in particular, be continuous. This means that the other protruding ring has no interruption like a recess. Specifically, this may mean that a minimum height is maintained along the longitudinal extension of the other protruding ring. In particular, the height above the adjacent face end of the longitudinal end of the inner cylinder portion along the longitudinal extension of the ring may be a substantially constant height. On the other hand, the protruding section can be either inelastic or rigid. One protruding section may primarily contribute to the locking function described herein, while the other protruding section may primarily contribute to the resilient sealing function.
[0013] According to one example, the other protruding section may extend lengthwise along the inner circumference of the elastic portion. Specifically, the other protruding section may extend lengthwise along the inner or innermost periphery of the elastic portion and at its longitudinal end, or in other words, longitudinally. Therefore, the sealing function of the other protruding section may be located at the inner or innermost periphery of the elastic portion and adjacent to the outer periphery of the inner cylinder portion.
[0014] According to one example, the other protruding segment and the other protruding segment may extend adjacent to each other in length. In particular, the other protruding segment and the other protruding segment may be directly adjacent to each other, especially along their entire length. Thus, a type of double seal with the two main functions mentioned herein is provided by means of the other protruding segment and the other protruding segment.
[0015] According to one example, the other protruding section can be vulcanized to the protruding section. Therefore, the other protruding section can be formed of a vulcanizable material, which can be a polymer material. Specifically, the elastic portion can be vulcanized together with the other protruding section to the inner cylinder portion or vulcanized separately. Typically, the inner cylinder portion with the protruding section can be manufactured as a single piece, or in other words, integrally or alternatively separately. Similarly, the elastic portion and the other protruding section can be manufactured as a single piece, or in other words, integrally or alternatively separately.
[0016] According to one example, the two longitudinal ends of the inner cylinder may include protruding sections, and the two longitudinal ends of the elastic portion may include the other protruding section. In other words, the protruding section and the other protruding section may be provided on each longitudinal end of the inner cylinder and the elastic portion to provide locking and sealing functions as described herein at the two longitudinal ends toward the U-clamp side of the U-clamp in the connector assembly.
[0017] According to one example, the protruding section and the other protruding section may comprise substantially the same height. Substantially the same height herein includes manufacturing deviations of up to 20%, particularly up to 10% or 5%, from each other. In each case, the height can be calculated along the longitudinal axis and from the end face, particularly the flat portion of the end face from which the protruding section extends in height along the longitudinal axis.
[0018] According to one example, the protruding section may include a pointed peak. The other protruding section may include a blunt peak. Using a pointed, or in other words, a sharp peak, the protruding section can easily engage with a U-shaped clip in a slotted or cut-in manner, thereby creating a robust locking function. Using a blunt peak, the other protruding section can create a strong and large seal against the U-shaped clip.
[0019] According to one example, the protruding section and / or the other protruding section may include a height in the range of 0.1 mm to 0.5 mm, particularly 0.2 mm to 0.4 mm. It has been found that at heights within this range, the protruding section can securely provide sufficient locking function without breaking, and the other protruding section can provide sufficient sealing function without becoming brittle or losing contact with the U-shaped clip.
[0020] According to one example, the protruding section and / or the other protruding section may include a radial width in the range of 0.1 mm to 0.5 mm, particularly 0.2 mm to 0.4 mm, wherein the radial direction is transverse to (particularly perpendicular to) the longitudinal axis. It has been found that at heights within this range, the protruding section can securely provide sufficient locking function without breaking, and the other protruding section can provide sufficient sealing function without becoming brittle or losing contact with the U-shaped clip.
[0021] According to a second aspect, a joint assembly for a vehicle suspension is provided, the joint assembly including a bushing according to a first aspect, a pivoting element, and a U-shaped clamp. The pivoting element is received inside the inner sleeve of the bushing and inside the U-shaped clamp. The bushing is arranged between opposing U-shaped clamp sides such that a protruding section is compressed in its height between one of the end faces and one of the U-shaped clamp sides.
[0022] When the other protrusion is present on the bushing, it can also be compressed in height between one of the end faces and one of the U-shaped clamping sides. Compression can be caused by an interference fit or press fit between the bushing and the U-shaped clamp, thereby deforming or compressing the protrusion and the other protrusion. On one hand, the protrusion can be compressed in height, but it can also be cut into or clamped into the U-shaped clamping side. The other protrusion can be compressed to create a sealing lip.
[0023] According to a third aspect, a vehicle suspension including the joint assembly of the second aspect is provided. The outer sleeve portion of the bushing is connected to a rotating component of the vehicle suspension, and the U-shaped clip is connected to another component of the vehicle suspension.
[0024] For example, the rotating component could be a rotating arm of a vehicle suspension. Another component connected to the U-clamp could be, for example, a static component, meaning it is not provided for relative movement within the vehicle suspension (unlike the rotating arm), but can move together with the entire vehicle suspension, for example, moving up and down when a vehicle with a vehicle suspension passes over a bump.
[0025] Another aspect of this disclosure may include a vehicle comprising the vehicle suspension of the third aspect. Additionally, the vehicle may include a frame to which the vehicle suspension may be attached. Another component may be part of the vehicle suspension and / or the frame.
[0026] Vehicles can be specific to, but not limited to, automobiles, such as buses or trucks. Vehicle suspensions can be specific to, but not limited to, automobile suspensions. Generally, while bushings are used in joint assemblies of vehicle suspensions, this does not preclude bushings from being used for other purposes, particularly in joint assemblies in systems or devices other than vehicle suspensions. Furthermore, joint assemblies are not limited to vehicle suspensions and can be used for other purposes.
[0027] Note that the examples above can be combined with each other, regardless of the aspects involved.
[0028] These and other aspects of this disclosure will become apparent from the examples described below and will be illustrated with reference to the examples described below. Attached Figure Description
[0029] Examples of this disclosure will now be described with reference to the following figures.

[0031] Figure 2 It shows Figure 1 A cross-sectional view of the joint assembly in the vehicle suspension.
[0032] Figure 3 It shows Figure 2A cross-sectional view of the bushing of the connector assembly.
[0033] Figure 4 It shows Figure 3 A perspective view of the inner cylinder of the bushing.
[0034] Figure 5 It shows Figure 3 A perspective view showing the details of the bushing. Detailed Implementation
[0035] The accompanying drawings are merely schematic representations and are intended to illustrate this disclosure only. In principle, identical or equivalent elements have the same reference numerals.
[0036] Figure 1 A perspective view of a portion of an exemplary vehicle suspension 1 for a vehicle (not shown) is shown. The vehicle suspension 1 includes typical components such as a wheel hub 40, a steering knuckle 50, a rotating component 20, etc. The vehicle suspension 1 is understood broadly herein and may include components of the vehicle frame. For example, the vehicle suspension 1 also includes another component 30 to which the wheel is linked when attached to the wheel hub 40; this other component may be a static component.
[0037] exist Figure 1 In the example, the connector assembly 10, having a bushing 100, a clevis 200, and a pivot element 300, is used to link or connect a rotating component 20 (e.g., a rotating arm) to another component 30 (e.g., a static component). Similarly, in Figure 1 The other bushing located at the steering knuckle 50 and / or any other bushing of the vehicle suspension 1 seen herein may have the same design as described further herein with respect to bushing 100, or may have a different design.
[0038] Figure 2 A cross-sectional view of bushing 100 is shown. Bushing 100 typically has a length extending along a longitudinal axis A, which may be the axis of symmetry of bushing 100.
[0039] The bushing 100 includes an inner cylindrical portion 110 having an opening 140 or through-hole extending along the length of the bushing 100 from one end to the other. A pivoting element 300 is inserted therein and thus extends inside the opening 140.
[0040] Here, the pivot element 300 is exemplarily shown as a screw element having a head 310. The screw element is secured between the head 310 and a nut 320 against a U-shaped clip 200, the nut 320 being positioned opposite the head 310 and screwed onto the corresponding threaded portion of the screw element. The head 310 and the nut 320 are secured against the U-shaped clip 200 from opposite sides, and a washer 330 is placed therebetween. Similar to the inner cylinder portion 110, the U-shaped clip 200 has an opening or through hole for the pivot element 300.
[0041] The bushing 100 also includes an elastic portion 130 made of an elastic material (e.g., a polymer or rubber), which is positioned adjacent to and completely surrounds or encloses the inner cylinder portion 110. The elastic portion 130 is in turn surrounded or enclosed by an outer cylinder portion 120, which may be made of the same material as the inner cylinder portion 110 (e.g., a metal material).
[0042] like Figure 2 As shown, by tightening the screw element on the outside of the U-shaped clip opposite to the inside 201 of the U-shaped clip, the bushing 100 is press-fitted between the inside 201 of the U-shaped clip 200.
[0043] As in Figure 1 As can be seen further, the rotating component 20 can be attached to the outside of the outer cylinder portion 120, and another component 30 can be attached to the U-shaped clamp 200.
[0044] exist Figure 1 The joint assembly 10 used in the vehicle suspension 1 Figure 2 In the bushing 100, the outer cylinder portion 120 is able to withstand shear forces F from the rotating component 20. To withstand these shear forces F, the bushing 100 may require a high shear load capacity. In addition, although the bushing 100 is press-fitted between the U-shaped clamps 200, water may potentially enter the space between the pivot element 300 and the inner cylinder portion 110, potentially leading to corrosion.
[0045] To provide high shear load capacity and waterproof seal, such as Figure 3 As shown in the cross-sectional view of the bushing 100, the inner cylinder portion 110 is provided with a protruding section 113, and the elastic portion 130 is provided with another protruding section 133. Specifically, as... Figure 2 and Figure 3 As shown, the inner cylinder portion 110 includes an opposite longitudinal end portion 111 having an end face 112, the end face 112 being mostly or substantially completely planar or flat except for the protruding section 113 disposed thereon.
[0046] As in Figure 4 Perspective view of the inner cylinder 110 and Figure 5As further seen in the detailed cross-sectional view of the bushing 100, the protruding section 113 extends a height H above the end face 112 in the longitudinal extension of the bushing 100 or inner cylinder portion 110. 113 Or in other words, extending beyond the end face by a height of 112 H 113 Height H 113 The length is measured along the longitudinal axis A and therefore along the bushing 100. The protruding section 113 also extends circumferentially along the longitudinal axis A in length L, specifically around the center C in the opening 140. More specifically, in this example, the protruding section 113 extends along the outer periphery 114 of the inner cylinder portion 110 in length L as a protruding ring on the end face 112. The protruding ring is provided on two opposite end faces 112 of the inner cylinder portion 110.
[0047] Similar to protruding segment 113, the elastic portion 130 includes another protruding segment 133, which is also formed as a protruding ring, but is formed of an elastic material instead of a hard or rigid material (e.g., a metal) like protruding segment 113. In this example, the other protruding segment 113 is designed as an elastomeric sealing lip and extends together in length and is directly adjacent to protruding segment 113 on the inner periphery 134 of the elastic portion 130, as... Figure 3 and Figure 5 As shown. Another protruding segment 133 extends above or beyond the end face 112 or an extension or imaginary plane of the end face 112 by a height H. 133 Alternatively, at the longitudinal end 131 of the elastic portion 130, it extends at a height H above or outside the end face 132 of the elastic portion 130. 133 In this respect, the extended or imaginary plane can extend from the end face 112 or be imagined to the elastic part 130. The height H of the two segments 113, 133 113 H 133 They can be basically the same.
[0048] Protruding segment 113 is exemplarily shown as having a sharp peak, and another protruding segment 133 is exemplarily shown as having a blunt peak. Furthermore, the protruding segment and the other protruding segment 133 have, as Figure 5 The width W shown 113 W 133 It can be measured in the radial direction R perpendicular to the longitudinal axis. Furthermore, the width W of the two segments 113 and 133... 113 W 133 They can be basically the same. Width W 113 W 133 In this article, it refers to the height H along segment 113,133. 113 H 133 Maximum width.
[0049] When the bushing 100 is inserted into the space between the inner sides 201 of the U-shaped clamps 200 and press-fitted, the protruding section 113 cuts into or clamps into the U-shaped clamps 200, thereby creating a locking function that enables the bushing to withstand high shear loads. The protruding section 113 thus at least partially extends at height H. 113 The upper part is compressed (this is in) Figure 2 The relatively small size of the protruding section 113 is not visible in the image. In addition, another protruding section 133 is compressed between the U-shaped clamping side 201 and the elastic part 130, thereby forming a sealing lip around the protruding section 113, thereby preventing the opening 140 or space between the pivot element 300 and the inner cylinder 110 from being filled with water and thus corroded.
[0050] As used herein, the phrase “at least one” in relation to a list of one or more entities should be understood to mean at least one entity selected from any one or more entities in the entity list, but not necessarily at least one of each entity specifically listed in the entity list, and does not exclude any combination of entities in the entity list. This definition also allows for the optional presence of entities other than those specifically identified in the entity list referred to by the phrase “at least one,” whether related to or unrelated to those specifically identified entities. Thus, as a non-limiting example, “at least one of A and B” (or equivalently, “at least one of A or B”, or equivalently, “at least one of A and / or B”) could in one example mean at least one (optionally including more than one) A, without B (and optionally including entities other than B); in another example, at least one (optionally including more than one) B, without A (and optionally including entities other than A); and in yet another example, at least one (optionally including more than one) A and at least one (optionally including more than one) B (and optionally including other entities). In other words, the phrases “at least one,” “one or more,” and “and / or” are open-ended expressions that are both connected and separate in operation. For example, each of the expressions “at least one of A, B, and C,” “at least one of A, B, or C,” “one or more of A, B, and C,” “one or more of A, B, or C,” and “A, B, and / or C” can mean a single A, a single B, a single C, A and B together, A and C together, B and C together, A, B, and C together, and optionally, any of the above combined with at least one other entity.
[0051] By studying the accompanying 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 multiple. The fact that certain measures are recited in mutually different dependent claims does not mean that a combination of these measures cannot be used advantageously. Any reference numerals in the claims should not be construed as limiting the scope of the claims.
