Technical Field
[0001] The present invention relates to a support member and a support arrangement. Background Technology
[0002] A support member is known to have an inner sleeve, an outer sleeve, and an elastic body disposed therebetween.
[0003] High axial stiffness is known to be achieved through the geometry of an inner sleeve and an outer sleeve, wherein the geometry overlaps axially and rests against the body of the elastic body. However, this does not create an axial stop.
[0004] However, the drawback of this type of support is the lack of a gradual rise in the axial direction. Summary of the Invention
[0005] Therefore, the objective of this invention is to create an improved axially rigid support in which an additional progressive leap is achieved in the axial direction.
[0006] According to the present invention, a support member is provided, which is traversed by a longitudinal axis, comprising an inner sleeve, an outer sleeve surrounding the inner sleeve on an outer circumferential side to form an intermediate space, and an elastomeric body located within the intermediate space and elastically connecting the inner sleeve and the outer sleeve, wherein the elastomeric body is materially bonded to the inner sleeve or materially bonded to the outer sleeve only, wherein the support member includes at least one axial stop member, the at least one axial stop member including a first stop member extending circumferentially on one of the inner sleeve and the outer sleeve and a second stop member extending circumferentially on the other of the inner sleeve and the outer sleeve, wherein the first stop member and the second stop member overlap each other axially and have axial free travel between their contact surfaces.
[0007] Thus, an axially rigid support was discovered, wherein a stiffness jump is achieved in the support itself by means of the at least one axial stop.
[0008] The axial stop can be formed entirely from the support member. The axial stop can form an axial stop in only one axial direction. In the opposite axial direction, a second axial stop can form another axial stop. The axial stop restricts the relative axial movement of the inner sleeve relative to the outer sleeve. The axial stop is activated when the first stop impinges on the second stop (axial stop position) during relative displacement of the inner and outer sleeves. This prevents further relative displacement in that axial direction. The axial stop can be formed in an intermediate space. This is used to integrate the axial stop into the support member.
[0009] Each stop includes a contact surface that faces each other. In the axial stop position, the stop contact surfaces of the axial stops are in contact with each other. The contact surface on the inner sleeve side can be formed by the inner sleeve / stop itself or by an elastomer body and / or an elastomer buffer. The contact surface on the outer sleeve side can be formed by the outer sleeve / stop itself or by an elastomer body and / or an elastomer buffer. Axial stops with at least one elastomer contact surface are used to reduce noise and protect materials. Furthermore, the elastomer contact surface provides a progressive stopping characteristic. When the axial stop is designed with two elastomer contact surfaces, this progressive stopping characteristic can be tuned more gently. The stops of the axial stops and / or radial stops can be formed by stop geometries such as annular flanges, annular grooves, or annular steps. One stop geometry can form multiple stops.
[0010] The inner sleeve and / or outer sleeve may each be formed or have a stop geometry that projects radially and extends circumferentially. The (corresponding) stop geometry forms a corresponding stop element. An annular shape serves as a uniform stop, distributing force as widely as possible. The stop element may be integrally formed from the inner sleeve and outer sleeve themselves. This avoids additional components. The inner sleeve may be integral. The inner sleeve may be the radially innermost supported component. This avoids additional components. The inner sleeve may have an axial through-hole. This is used to accommodate fasteners such as screws. It is conceivable that the support element consists only of the inner sleeve, outer sleeve, and elastomer body. This avoids additional components.
[0011] Free travel can exist between the contact surfaces of the two stops of the axial stop. In the axial stop position, the length of the free travel is zero. The free travel can extend axially parallel to the longitudinal axis. The axial stop can rest against the load path between the inner sleeve, the elastomer body, and the outer sleeve.
[0012] The elastomer body can directly connect the inner and outer sleeves to each other. This reduces the radial installation space requirement. The elastomer body is only material-bondedly connected to one of the inner and outer sleeves to allow for the molding of complex geometries. If the elastomer body is material-bondedly connected to the inner sleeve but not to the outer sleeve, the tool geometry of the vulcanizing mold used to shape the outer elastomer body can be designed almost arbitrarily. This maximizes the design freedom of the external geometry of the elastomer body, resulting in good adjustability of stiffness and free travel when interacting with the assembled outer sleeve. Similarly, if the elastomer body is only fixed to the outer sleeve, and then the unit consisting of the outer sleeve and the elastomer body is installed around the inner sleeve, the design freedom of the elastomer body is also high. This is especially true when the outer sleeve is divided into two parts. The elastomer body can be non-material-bondedly attached to the other of the inner and outer sleeves. The elastomer body can be a single piece and / or the only elastomer body in the intermediate space. This avoids additional components.
[0013] According to an improved embodiment of the support member, it may include at least one axial stiffening element comprising an annular notch extending circumferentially on one of the inner and outer sleeves, and an annular protrusion extending circumferentially on the other of the inner and outer sleeves, the annular protrusion extending radially toward the annular notch, wherein the annular protrusion is elastically supported on the annular notch via an elastomer body. Preferably, the annular notch and the annular protrusion overlap each other axially. Axial stiffness can be adjusted by means of the axial stiffening element. The elastomer body can completely fill the intermediate space between the annular notch and the annular protrusion. This serves to increase axial stiffness. The axial overlap also serves to increase axial stiffness. It is conceivable that the support member comprises a single axial stiffening element. This is advantageous for an axially compact structure.
[0014] According to an improved version of the support, the outer sleeve can be formed from two shell halves. The division of the shell halves at their longitudinal gap edges can extend axially. The two-piece outer sleeve can be easily used to form an axial stop. Thus, the shell halves can be installed radially, thereby making the undercut caused by the axial stop irrelevant to vulcanization. Another advantage is that, since the outer sleeve is divided into two shell halves, the design freedom of the elastomer body is maximized, because the undercut would otherwise be very limited in its forming within the vulcanizing tool.
[0015] According to an improved embodiment of the support member, a first stop and / or a second stop can support an axial elastomeric buffer and / or a radial elastomeric buffer. The stop is a stop for an axial stop. The elastomeric buffer can be integrally formed from an elastomeric body and / or an elastomeric cover layer. The elastomeric buffer can be material-bonded to the stop. This prevents slippage, improves progressiveness, and extends the service life of the stop system. The axial elastomeric buffer restricts axial free travel. The axial elastomeric buffer can be axially spaced apart from the contact surface of another stop. The radial elastomeric buffer restricts radial free travel. The radial elastomeric buffer can be radially spaced apart from the contact surface of a radial stop.
[0016] According to one improvement to the support, the elastomer body can be a thermoplastic elastomer body. This is particularly advantageous if the shell half is made of plastic, as it is material-bondedly attached to the shell half. Here, the thermoplastic elastomer body can be co-molded with the shell half in a two-component (2K) process. This reduces manufacturing costs and allows for highly complex geometries. Such a shell half with an attached elastomer body can be mounted around an inner sleeve during installation, thereby forming the support.
[0017] According to an improved version of the support, the inner sleeve may form a screw head receiving space at one end, which at least partially overlaps with the annular notch in the axial direction. This screw head receiving space can, for example, at least segmentally accommodate a screw head, nut, or centering pin. This reduces the axial installation space requirement. The axial overlap also contributes to a very compact axial support. It is conceivable that the radially outer periphery of the inner sleeve of the screw head receiving space is larger than the inner periphery of the annular protrusion on the outer sleeve. This segment of the inner sleeve thus overlaps axially with the annular protrusion. With the screw head receiving space and the annular protrusion positioned adjacent to each other in the axial direction, the segment of the inner sleeve forming the screw head receiving space can serve as axial support for the annular protrusion in the axial stiffening element. This mutual nesting of the annular notch, screw head receiving space, centering pin receiving space, and screw through-hole reduces the axial and radial installation space requirements. The screw head receiving space can be a segment of the axial through-hole.
[0018] According to an improved embodiment of the support, the inner sleeve may have a screw through-hole, wherein an annular notch is radially positioned on the outer periphery of the screw through-hole. The screw through-hole may be a section of an axial through-hole. The screw through-hole can directly extend axially into the screw head receiving space at one end. This reduces the axial installation space requirement. The screw through-hole may be cylindrical. This allows the bottom of the annular notch in the inner sleeve to have the smallest possible outer diameter. The inner diameter of the screw through-hole can be smaller than the inner diameter of the screw head receiving space. This reduces the radial installation space requirement.
[0019] According to an improved embodiment of the support member, the inner sleeve may have a centering pin receiving space, preferably located at the opposite axial end of the screw head receiving space. Here, the screw through hole can directly enter the centering pin receiving space axially. This reduces the axial installation space requirement. For example, the centering pin of a battery support, motor, or assembly support member can be inserted into the centering pin receiving space and fixed there by means of a fastening element (e.g., by means of a screw). It is conceivable that the outer circumference of the inner sleeve in the radial direction of the centering pin receiving space is larger than the inner circumference of the annular protrusion on the outer sleeve. This section of the inner sleeve therefore has axial overlap with the annular protrusion. When the centering pin receiving space and the annular protrusion are positioned adjacent to each other in the axial direction, the section of the inner sleeve forming the centering pin receiving space can serve as axial support for the annular protrusion in the axial stiffening member. This mutual nesting of the annular notch, screw head receiving space, centering pin receiving space, and screw through hole reduces the axial and radial installation space requirements. The centering pin receiving space can be a section of the axial through hole.
[0020] According to an improved embodiment of the support, the inner diameter of the annular protrusion may be smaller than the inner diameter of the stop on one of the inner sleeve and outer sleeve, and / or smaller than the outer diameter of the stop on the other of the inner sleeve and outer sleeve. This applies to all stops if multiple stops are positioned on the inner / outer sleeve. This geometry favors a large radial extension of the annular protrusion and a compact structure, allowing for maximum overlap with the annular notch. Furthermore, this also contributes to a compact structure. The stop or annular protrusion has an inner diameter when positioned on the outer sleeve. It has an outer diameter when positioned on the inner sleeve. The stop is either the first or second axial stop, depending on its positioning.
[0021] According to an improved design, the inner sleeve may have a cylindrical face section on each side of the annular notch in the axial direction. If the elastomer body is vulcanized on one side of the inner sleeve, its axial extension within the cylindrical face section region can be slightly altered. This slight change in extension results in a small adjustment of stiffness without significantly altering the failure mechanism or the location of the strain peak. This is especially true when the geometry (particularly the geometry of the inner and outer sleeves) remains unchanged. Therefore, the cylindrical face sections improve modularity and allow for easy adjustment of the design stiffness when using the same inner and outer sleeves. The cylindrical face sections can be axially separated from the annular notch.
[0022] According to an improvement of the support member, the support member may include radial stops comprising a third stop extending circumferentially on one of the inner sleeve and the outer sleeve, and a fourth stop extending circumferentially on the other of the inner sleeve and the outer sleeve, wherein the third and fourth stops may overlap each other radially and have radial free travel between their contact surfaces. The radial stops restrict the relative movement of the inner sleeve with respect to the outer sleeve in the radial direction.
[0023] Each stop member has a contact surface, and these contact surfaces face each other. In the radial stop position, the stop contact surfaces of the radial stop members are in contact with each other. The contact surface on the inner sleeve side may be formed by the inner sleeve itself or by an elastomer body and / or an elastomer buffer. The contact surface on the outer sleeve side may be formed by the outer sleeve itself or by an elastomer body and / or an elastomer buffer. Radial stops with at least one elastomer contact surface are used to reduce noise and protect materials. Radial stops with two elastomer contact surfaces provide a gentler stopping characteristic.
[0024] Radial free travel can exist between the contact surfaces of the two radial stops. In the radial stop position, the length of the radial free travel is zero. The free travel can extend radially perpendicular to the longitudinal axis. The axial stop can rest against the load path between the inner sleeve, the elastomer body, and the outer sleeve.
[0025] It is conceivable that one of the stops of the axial stop and one of the stops of the radial stop are formed by the same stop geometry. This is advantageous for a compact structure. Preferably, one stop geometry forms two or three stops, for example, two stops of two axial stops and one stop of a radial stop. This is advantageous for a further compact structure. Preferably, all stops of the first and second axial stops and two stops of the radial stop are formed by the same stop geometry on each side of the intermediate space. This is advantageous for an even more compact structure. In the latter case, the stop geometry (e.g., an annular flange) may extend radially into another stop geometry (e.g., an annular groove). The first axial stop may be formed on one axial side of the stop geometry / annular flange. The second axial stop may be formed on the opposite axial side of the stop geometry / annular flange. The radial stop may be formed radially on the stop geometry / annular flange. The stop geometry / annular flange thus advantageously serves a triple function.
[0026] According to an improved embodiment of the support, the outer sleeve may have a mounting stop on its outer circumferential side. The outer sleeve may have only one mounting stop. The mounting stop may be axially arranged at one end. At the other axial end, the outer sleeve may not have a mounting stop. This is used for directional mounting and precise axial positioning. The mounting stop may be an annular collar. The mounting stop firstly serves as a terminal stop when the support arrangement is (e.g., pressed) into the fixing hole, and secondly, the mounting stop defines the guide direction into the fixing hole.
[0027] According to an improved embodiment of the support member, the outer sleeve may have a mounting surface defining the outer periphery of an imaginary cylinder, wherein a first stop and / or a second stop are at least partially positioned within the imaginary cylinder. Alternatively or additionally, a third and / or a fourth stop may also be at least partially positioned within the imaginary cylinder. Preferably, all stops are at least partially, and more preferably completely, positioned within the imaginary cylinder. This facilitates a radially compact structure. The support member is radially abutted against the mounting surface on the fixing hole, preferably by an interference fit.
[0028] According to an improved embodiment of the support, the annular notch and / or annular protrusion are V-shaped in the longitudinal section. Preferably, the surfaces of the annular notch and annular protrusion extending parallel to each other are perpendicular. Due to this V-shape, compressive stress and shear force are generated in the elastomer body, thereby obtaining a gentle but progressive radial characteristic curve.
[0029] According to an improved embodiment, the support member may include a second axial stop member, comprising: a first stop member extending circumferentially on one of the inner sleeve and the outer sleeve, and a second stop member extending circumferentially on the other of the inner sleeve and the outer sleeve, wherein the first stop member and the second stop member overlap each other axially and have axial free travel between their contact surfaces.
[0030] The second axial stop can act in the opposite direction to the first axial stop. Through the two axial stops, the relative movement of the inner sleeve to the outer sleeve is restricted in two opposite axes. The first and second axial stops can share a common stop.
[0031] According to the present invention, a support arrangement is further provided, comprising: a support member and a fixing hole, the support member being fixed in the fixing hole by means of an interference fit.
[0032] The advantages described above regarding the support components also apply to the support arrangement, and are referenced hereforth. The support arrangement may include a connection structure with fixing holes.
[0033] It can be envisioned that the support arrangement has two such support members in the corresponding fixing holes, wherein the distance between these support members is less than twice the outer diameter of the support member, or less than twice the diameter of the imaginary cylinder. The support members can be arranged adjacent to each other radially. If two support members are arranged side by side with a very small radial spacing, they together can function as a single support member with high torsional stiffness. In this case, it can also be called an anti-torsional support system or an anti-torsional support arrangement.
[0034] It is conceivable that at least one end of the support extends from the fixing hole, and preferably, the axial stop is at least partially positioned outside the fixing hole. This allows the fixing hole to be shortened.
[0035] The design and advantages described for one axial stop or for a stop of an axial stop are equally applicable to the same other axial stop or for another stop of an axial stop. If a component is disclosed multiple times, the design and advantages described for only one component should also be considered as optionally disclosed to the other corresponding components. Axial and axial directions extend parallel to the longitudinal axis. Radial and radial directions extend perpendicular to the longitudinal axis. Circumferential and circumferential directions extend around the longitudinal axis. Attached Figure Description

[0092] In the accompanying drawings, identical or corresponding elements are denoted by the same reference numerals, and therefore will not be described again unless necessary. To avoid repetition, features already described will not be repeated, and unless explicitly excluded, they apply to all elements with the same or corresponding reference numerals. The disclosure contained throughout this specification can be extrapolated to the same parts with the same reference numerals or the same part names. Furthermore, the orientation descriptions selected in the specification, such as above, below, side, etc., are for the purposes of the directly described and illustrated drawings, and can be extrapolated to the new positions when the positions change. In addition, some individual features or combinations of features derived from the different embodiments shown and described can each constitute an independent, inventive, or in accordance with the present invention.
[0093] The radial direction R extends perpendicular to the longitudinal axis L. The circumferential direction U extends around the longitudinal axis L. The axial direction A is arranged along the longitudinal axis L.
[0094] Figure 1The support member 2 is shown in longitudinal section, through which the longitudinal axis L passes. The support member 2 includes an integral inner sleeve 100, an integral outer sleeve 200 surrounding the inner sleeve 100 on its outer circumference to form an intermediate space 4, and an integral elastomer body 300 in the intermediate space 4 that elastically and directly connects the inner sleeve 100 to the outer sleeve 200. The inner sleeve 100 has a through hole 118 in the axial direction A. The outer sleeve 200 is formed by two shell halves 208 and 210.
[0095] The elastomer body 300 is connected to the inner sleeve 100 only by material bonding, and rests against the outer sleeve 200 without material bonding. The elastomer body 300 is a single piece and is the only elastomer body in the intermediate space 4.
[0096] The support member 2 has two axial stops 6.1 and 6.2. Each axial stop 6.1 and 6.2 restricts the relative movement of the inner sleeve 100 with respect to the outer sleeve 200 in the axial direction A.
[0097] Each axial stop 6.1, 6.2 includes a first stop 102 located on the inner sleeve 100 and extending in the circumferential direction U. Each axial stop 6.1, 6.2 further includes a second stop 202.1, 202.2 located on the outer sleeve 200 and extending in the circumferential direction U. The first stop 102 and the second stop 202.1, 202.2 of each axial stop 6.1, 6.2 have overlaps C1.1, C1.2 with each other in the axial direction A, and have axial free travel F1.1, F1.2 between their contact surfaces 104.1, 104.2, 204.1, 204.2. The respective contact surfaces 104.1, 104.2, 204.1, 204.2 of each axial stop 6.1, 6.2 are opposite to each other.
[0098] When in the axial stop position, contact surfaces 104.1, 104.2, 204.1, and 204.2 are in contact with each other. Contact surfaces 104.1 and 104.2 on the inner sleeve side are formed by the elastomer body 300. Contact surfaces 204.1 and 204.2 on the outer sleeve side are formed by the outer sleeve 200 itself.
[0099] Free travel F1.2 and F1.2 exist between their respective contact surfaces 104.1, 104.2, 204.1, and 204.2. Free travel F1.2 and F1.2 extend parallel to the longitudinal axis L.
[0100] The inner sleeve 100 has an annular flange 116, which forms a stop geometry and defines a first stop 102 for two axial stops 6.1, 6.2. The outer sleeve 200 has two annular flanges 218, 220, which are arranged on both sides of the annular flange 116 on the inner sleeve side and form a stop geometry. The annular flanges 218, 220 define second stops 202.1, 202.1. The annular flanges 218, 220 on the two outer sleeve sides define annular grooves 222. The annular flanges 116, 218, 220 project radially R and extend circumferentially U.
[0101] Axial stops 6.1 and 6.2 are formed entirely of support member 2. Each axial stop 6.1 and 6.2 forms an axial stop in only one axial direction, with the directions of action opposite to each other. Axial stops 6.1 and 6.2 are formed in the intermediate space 4.
[0102] The first stop 102 supports an axial elastomeric buffer 302.1, 302.2 and a radial elastomeric buffer 304. The elastomeric buffers 302.1, 302.2 and 304 are integrally formed from the elastomeric body 304 and form an elastomeric covering layer. The elastomeric buffers 302.1, 302.2 and 304 are materially bonded to the stop 102.
[0103] The support member 2 also has an axial stiffening member 8. The axial stiffening member 8 includes an annular recess 106 extending circumferentially along the U direction on the inner sleeve 100 and an annular protrusion 206 extending circumferentially along the U direction on the outer sleeve 200. The annular protrusion 206 extends radially toward the annular recess 106. The annular protrusion 206 is elastically supported on the annular recess 106 by an elastic body 300, wherein the annular recess 106 and the annular protrusion 206 overlap each other C2 in the axial direction A. The elastic body 300 completely fills the intermediate space between the annular recess 106 and the annular protrusion 206. A cylindrical surface section 122 is connected to the left and right sides of the annular recess 106. The inner diameter of the annular protrusion 206 is smaller than the outer diameter of the first stop 102 on the inner sleeve 100, and smaller than the inner diameter of the stops 202.1 and 202.2 on the outer sleeve 100. The annular notch 106 and the annular protrusion 206 are V-shaped in longitudinal section. The surfaces of the annular notch 106 and the annular protrusion 206 that are opposite to each other extend parallel to each other.
[0104] The through-hole 118 of the inner sleeve 100 comprises multiple sections. At one end, the inner sleeve 100 forms a screw head receiving space 108, which at least partially overlaps C3 with the annular notch 106 in the axial direction A. The screw head receiving space 118 is one section of the through-hole 118. Adjacent to it is a screw through-hole 110 of the inner sleeve 100, wherein the annular notch 106 is positioned radially R on the outer periphery of the screw through-hole 110. The screw through-hole 110 is another section of the through-hole 118. The screw through-hole 110 is cylindrical, and its diameter is smaller than that of the screw head receiving space 108. Adjacent to the screw through-hole 110 is a centering pin receiving space 120; a centering pin, as part of a battery, motor, or assembly, can be pushed into this receiving space and secured thereby by means of a screw. The diameter of the screw through-hole 110 is smaller than that of the centering pin receiving space 120. Screw head receiving space 118 and centering pin receiving space 120 are formed on two opposite axial sides of inner sleeve 100.
[0105] The support member 2 also has a radial stop 12. This radial stop includes a third stop 112 extending circumferentially along the U direction on the inner sleeve 100 and a fourth stop 212 extending circumferentially along the U direction on the outer sleeve 200. The third stop 112 and the fourth stop 212 overlap each other radially R by C4 and have radial free travel F2 between their contact surfaces 114, 214. It can be seen that the annular flange 116, as the stop geometry, forms two first stops 102 of the two axial stops 6.1 and 6.2, and the third stop 112 of the radial stop 12. The radial stop 12 restricts the relative movement of the inner sleeve 100 with respect to the outer sleeve 200 in the radial direction R. The stops 112 and 212 each have a contact surface 114, 214, which are opposite each other. The contact surface 114 on the inner sleeve side is formed by the elastomer body 300. The contact surface 214 on the outer sleeve side is formed by the outer sleeve itself. The radial free travel F2 exists between the two contact surfaces 114 and 214. The free travel F2 extends radially R perpendicular to the longitudinal axis L.
[0106] The outer sleeve 200 has a mounting surface 224 defining the outer periphery of an imaginary cylinder D, wherein all stops 102, 202.1, 202.2, 112, and 212 are fully positioned within the imaginary cylinder D. The support member 2 abuts against the fixing hole 14 of the connecting structure 16 radially R via the mounting surface 224, preferably by means of an interference fit. The support arrangement 10 includes the support member 2 within the fixing hole 14. The support member 2 extends axially from the fixing hole 14 at both ends, with a first axial stop 6.1 positioned inside the fixing hole 14 and a second axial stop 6.2 positioned outside the fixing hole 14.
[0107] The outer sleeve 200 has a single mounting stop 216 on its outer circumferential side and at one axial end. At the other axial end, the outer sleeve 200 has no mounting stop. The mounting stop 216 is an annular collar. It rests against the connecting structure.
[0108] Figure 2 Another support member 2 is shown in longitudinal section. To avoid repetition, the following section discusses... Figure 2 Only describe its relationship with Figure 1 The difference is that features that have been described but not repeated should also be considered as disclosed and described.
[0109] Now, the support member 2 no longer has two axial stops 6.1 and 6.2, but only one axial stop 6.1. The elastomer body 300 is now material-bonded to the outer sleeve 200, while non-material-bondedly abutting against the inner sleeve 100. Therefore, the positioning of the elastomer buffers 302.1, 302.2, and 304 has also moved from the inner sleeve 100 to the outer sleeve 200. The contact surfaces 104.1 and 114 on the inner sleeve side are formed by the inner sleeve 100 itself. The contact surfaces 204.1 and 214 on the outer sleeve side are formed by the elastomer body 300.
