[0002] Damping devices of the type mentioned in the introduction are used in motor vehicle construction to damp vibrations transmitted from the engine to vehicle components, such as the transmission, during driving or even when stationary, thereby improving driving comfort. Known damping devices comprise a spring device made of rubber and a main body, wherein the main body is vibratingly connected to the vehicle component to be damped via the spring device. If the vehicle component connected to the damping device begins to vibrate, the main body also amplifies the vibration with a 90° phase difference, wherein the vibration is damped by the spring device.

[0003] WO 01 / 92752 A1, US Pat. No. 10,006,514 B2, US Pat. No. 9,702,423 B2, and CN 106969074 B disclose vibration dampers comprising a vibration damping body, a fastening element, and a spring device in the form of a rubber body. To secure the spring device to the vibration damping body and the fastening element, the spring device has two circumferential receiving grooves that positively engage corresponding projections of the vibration damping body and the fastening element. Summary of the Invention

[0004] The present invention is based on the object of providing a damping device and a method for mounting a damping device which allow improved and at the same time inexpensive production and assembly.

[0005] In order to achieve this object, a damping device and a method for installing a damping device are proposed.

[0006] A damping device for absorbing and / or damping vibrations of a vehicle part or for isolating and / or damping vibrations of a vehicle component, comprising at least one main part, at least one fastening element for fixing the damping device to the vehicle part or a vehicle part adjacent to the main part, and at least one spring device for connecting the main part to the fastening element in a vibratory manner, wherein the main part or the fastening element has at least one fastening mechanism for fixing the spring device, and the fastening element, the main part and / or the vehicle part have at least two supporting mechanisms for supporting the spring device, wherein the spring device has at least one fixing device fixed to the fastening mechanism and at least two supporting parts supported on the supporting mechanism in opposite axial directions, wherein the fastening mechanism and the supporting mechanism are axially spaced apart from each other such that the spring device is prestressed when the supporting parts abut against the supporting mechanism.

[0007] Here, the axial direction corresponds to the longitudinal direction of the damping device. Here, the radial direction should be understood to mean a direction transverse to the axial direction. Opposite axial directions mean that the two bearings point in opposite directions, i.e., the first bearing points in a first axial direction and the second bearing points in a second axial direction.

[0008] The damping device can be used to absorb and / or damp a vehicle part such as a transmission, a rear cover or a chassis. When the damping device is used to absorb and / or damp a vehicle part such as a transmission, a rear cover or a chassis, the damping device may also be referred to as a shock absorber. The damping device may also be used to isolate and / or damp a vehicle component such as a pump, an air compressor, a control component or a powertrain. When the damping device is used to isolate and / or damp a vehicle component, the vehicle component forms the main body of the damping device and the fastener is fixed to the vehicle part adjacent to the vehicle component. When the damping device is used to isolate and / or damp a vehicle component, the damping device may also be referred to as a decoupling device.

[0009] Due to the structural preload between the spring device, the main body, the fastening element, and / or the vehicle part, the joint can be achieved solely by support on the joint side, so that at least one of the support parts can only be placed on one of the support surfaces. Furthermore, due to the structural preload, the two support parts are pressed against the support surface on both sides due to the compressive force, thereby creating a two-sided form fit from the simple support, which secures the spring device to the main body or fastening element. Consequently, there is no need to connect the spring device to the main body, the fastening element, and / or the vehicle part by material connection. This makes the damping device simple and inexpensive to manufacture.

[0010] To generate the preload, the fixing device is advantageously first connected to the fastening mechanism in a form-fitting manner, and the spring device is compressed so that the support portion can be placed on the support mechanism. Advantageously, the fixing device is connected to the fastening mechanism in a form-fitting manner to generate the preload, and for final fastening, the spring device is overstressed by the fastener and / or the main part and thereby preloaded, since the first support portion abuts a first support surface of the main part or the fastener, and the second support portion abuts a second support surface of the main part or the fastener. Furthermore, for final fastening, the first and / or second support portions can rest against a screwing surface of the vehicle part, whereby the damping device is screwed to the vehicle part to apply the preload, and the spring device is thereby compressed and preloaded.

[0011] In an advantageous design, the main body is made of metal. Advantageously, the main body can be cylindrical or polygonal. Advantageously, the main body can be a pump, air compressor, control unit, or powertrain of a vehicle.

[0012] In one advantageous design, the main body has an opening. In one advantageous design, the opening extends from a first end of the main body to a second end of the main body. Further advantageously, the opening extends from a first end of the spring device to a second end of the spring device. In one advantageous design, the protrusion protrudes radially from the inner wall of the opening. Advantageously, a trapezoidal recess connects each of the two protrusions, and one of the protrusions of the spring device protrudes into the trapezoidal recess. In one advantageous design, a semicircular recess is provided between the two trapezoidal recesses, so that the outer wall of the spring device can abut against the recess and limit radial deflection of the main body.

[0013] In one advantageous embodiment, the fastener is designed as a sleeve or a cuboid container with a bottom surface and side walls surrounding the bottom surface. The fastener can be made of metal or plastic, in particular fiber-reinforced plastic. In one advantageous embodiment, the fastener has a through-hole. The through-hole allows the damping device to be fixed to an adjacent vehicle part, such as a transmission, a rear lid, or a chassis. Alternatively, the fastener can have a blind hole for fixing to an adjacent vehicle part, or it can be designed as a pin with a partially circumferential edge on the end side, which serves as a contact surface with the vehicle part to be fixed.

[0014] In an advantageous embodiment, the spring device comprises one or more rubber springs, one or more metal springs or one or more plastic springs. It is also advantageous if the spring device is designed as a hollow body.

[0015] In an advantageous design, the fastening mechanism is formed by the fastener or main part in an integrated and materially unified manner. In addition, the fastening mechanism can be a separate part, which can be connected to the fastener or main part in a form-fitting and / or materially engaged manner.

[0016] In an advantageous embodiment, the support mechanism is formed in one piece and of a uniform material from the fastening element, the main element and / or the vehicle part. Alternatively, the support mechanism can be a separate part that can be connected to the fastening element, the main element and / or the vehicle part by a form-fitting, force-fitting and / or materially bonded manner.

[0017] In one advantageous embodiment, the first support portion abuts a first support mechanism of the main body, fastener, or vehicle part, and the second support portion abuts a second support mechanism of the main body, fastener, or vehicle part. In one advantageous embodiment, the support portions are spaced apart from one another. In one advantageous embodiment, the support portions are spaced apart in the radial and axial directions of the fastening device. The support mechanisms advantageously each have a support surface against which the support portion abuts.

[0018] Advantageously, the fixing device surrounds the fastening mechanism in a form-fitting manner.Also advantageously, the fixing device consists of one or two fixing parts formed on the spring device.

[0019] In an advantageous embodiment, the spring device has a length between the fixing device and the support part in the unmounted state that is greater than the distance between the fastening device and the support part. As a result, the spring device is compressed and prestressed when it abuts the support part, so that the spring device exerts a pressing force on the support part in order to hold the main part or the fastening element between the support parts in a form-fitting and force-locking manner.

[0020] In an advantageous embodiment, the support portions overlap axially when resting against the support means, thereby exerting a uniform pressing force on the support means.

[0021] In an advantageous embodiment, the support portions are spaced apart in the axial direction A. Thus, the support portions can form a receiving groove for receiving a part of the main part or of the fastening element in a form-fitting and force-fitting manner.

[0022] In an advantageous embodiment, the fixing device is fixed to the fastening mechanism in a form-fitting and force-fitting manner, thereby providing a simple and inexpensive fixation. In an advantageous embodiment, the form-fitting connection between the fixing device and the fastening mechanism is achieved by clamping.

[0023] In one advantageous embodiment, the fixing device comprises at least one partially circumferential groove, and the fastening mechanism comprises at least one projection corresponding to the circumferential groove. This provides a simple and inexpensive form-fitting and force-locking connection between the spring device and the main body or the fastening element. Furthermore, the fixing device advantageously comprises at least one circumferential groove, and the fastening mechanism comprises at least one projection corresponding to the circumferential groove. In one advantageous embodiment, the projection projects radially from the inner wall of the opening of the main body into the opening.

[0024] In one advantageous embodiment, the groove and / or projection can be produced during the manufacture of the spring device and the main part or the fastener. Thus, for example, the projection can be produced during cold extrusion, casting, or turning of the main part or the fastener. Alternatively, the projection can be realized by an additional component that can be connected to the main part or the fastener. The additional component can be a clamping ring or produced by plastic overmolding.

[0025] In one advantageous embodiment, the support means is designed as at least one shoulder or recessed portion projecting from the main part or fastener. This support surface can thus be formed in a simple and inexpensive manner during the manufacture of the main part itself or by means of an additional component that can be connected to the main part or fastener. Thus, for example, the shoulder or recessed portion can be produced during cold extrusion, casting, or turning of the main part or fastener. Furthermore, the shoulder can also be realized by means of an additional component that can be connected to the main part or fastener. This additional component can be a clamping ring or produced by plastic overmolding. In one advantageous embodiment, the recessed portion is a blind hole.

[0026] In an advantageous design, at least one protrusion and at least one shoulder overlap in the radial direction to form an anti-loss mechanism. The anti-loss mechanism prevents the main body from detaching from the damping device and thereby causing damage to the vehicle when the spring device is damaged. In addition, the anti-loss mechanism withstands the load that occurs in the event of an accident. The outer diameter of the protrusion is advantageously greater than or equal to the inner diameter of the protruding shoulder to produce a radial overlap. Advantageously, the inner diameter of the protrusion is smaller than or equal to the outer diameter of the protruding shoulder. In addition, in the case where at least one protrusion and at least one shoulder do not completely overlap in the radial direction, the force of the anti-loss mechanism can also be high due to the deformation of the spring device and the closing of the gap formed between the components and is sufficient to function as an anti-loss mechanism.

[0027] In an advantageous design, at least one pin protrudes from the main body, the pin extending through the edge of an opening in the fastener, wherein the pin and the edge of the opening overlap in the radial direction to form an anti-lost mechanism, in particular an anti-lost mechanism in the radial direction. In an advantageous design, the pin protrudes from the main body, the pin extending through the edge of an opening in the fastener, wherein the pin and the edge of the opening overlap in the radial direction to form an anti-lost mechanism, in particular an anti-lost mechanism in the radial direction.

[0028] In an advantageous embodiment, the spring device has at least one axial stop and / or at least one radial stop, which cooperate with the fastener and / or the main body to limit the deflection of the main body relative to the fastener. Advantageously, the at least one axial protrusion is designed as a ridge, which rests against the top or bottom side of the main body and cooperates with a flange formed on the fastener. In an advantageous embodiment, the spring device has two axial stops, wherein a first axial stop rests against the top side of the main body and a second axial stop rests against the bottom side of the main body and cooperates with a flange formed on the fastener and / or a vehicle part. In an advantageous embodiment, the axial stops are arranged in the immediate vicinity of the fixing portion. In an advantageous embodiment, the inner and / or outer contour of the spring element forms the at least one radial stop. It is also advantageous if the radial stop cooperates with a setback in the fastener or the main body, in particular in the main body.

[0029] In an advantageous design, the spring device has additional radial strips on its outside and / or inside. Advantageously, the radial strips act parallel to the spring portion and influence the frequency expansion between radial and axial directions. Thus, the frequency expansion can be adjusted between radial and axial directions by a rigid portion between the spring device and the second radial stop designed as an additional spring. In an advantageous design, the radial strips are radial rubber strips. In an advantageous design, the radial strips abut against the fastener and / or the main body. The damping device is preferably designed to be hard in the radial direction and soft in the axial direction because of the radial strips. In an advantageous design, the radial strips are designed to be protrusions protruding radially from the spring device, which partially or completely surround the spring device.

[0030] In one advantageous embodiment, the spring device is inserted into an opening in the main part or the fastening element, and at least one section of the main part or the fastening element is inserted into a through-hole in the spring device. To generate the preload, the spring device is first inserted into the opening in the main part or the fastening element so that the fastening device is connected to the fastening mechanism in a form-fitting manner. Subsequently, for final fastening, at least one section of the main part or the fastening element is inserted into the through-hole in the spring device so that the spring device is overstressed and preloaded by the first support portion resting on a first support surface of the main part or the fastening element and the second support portion resting on a second support surface of the main part or the fastening element, or by final fastening such that the second support portion rests against a vehicle part and the spring device is preloaded by mounting the damping device on the vehicle.

[0031] In an advantageous embodiment, the support portion and the support mechanism comprise a surface that is inclined relative to the longitudinal axis of the damping device or a surface that is perpendicular relative to the longitudinal axis of the damping device, so that the spring device can exert a sufficiently large pressing force on the support portion to reliably connect the main body and the fastening element.

[0032] In an advantageous design, the fixing device and each supporting portion are connected via a spring portion that is inclined relative to the longitudinal axis of the damping device. The oblique placement of the spring portion can easily transfer the compressive force originating from the preload to the supporting mechanisms spaced apart in the radial and axial directions of the fixing device. Advantageously, the fixing device is formed by two fixing portions, each of which is connected to one of the supporting portions via a spring portion. In addition, the fixing device can be formed by a fixing portion, wherein each supporting portion is connected to the fixing portion via a spring portion. In an advantageous design, the spring device has a first spring portion and a second spring portion, which are obliquely disposed with respect to the longitudinal axis of the damping device. The first spring portion and the second spring portion are preferably axially opposed. In an advantageous design, the spring device can also have only one spring portion, which is obliquely disposed with respect to the longitudinal axis of the damping device.

[0033] In an advantageous design, the spring device comprises at least one partially sleeve-shaped rubber body, a partially sleeve-shaped plastic body or a partially sleeve-shaped metal body. In an advantageous design, the spring device has two sleeve-shaped rubber bodies. In an advantageous design, the spring portion is designed as a rubber strip that is tilted with respect to the longitudinal axis of the damping device. When the spring device is composed of a single sleeve-shaped rubber body, the rubber body may have a fixing portion, two spring portions and two supporting portions that form the fixing device. When the spring device is composed of two rubber bodies, each rubber body has a fixing portion, a spring portion and a supporting surface. In an advantageous design, the cross-section of the rubber body is designed to be L-shaped, C-shaped or S-shaped. When the spring device is composed of two sleeve-shaped rubber bodies, the two rubber bodies form a receiving groove in the installed state in an advantageous design, and the supporting mechanism can be installed, especially pressed into the receiving groove. If the fixing device is designed as a container in which the main body is vibratingly seated, the spring device, in one advantageous embodiment, comprises four sleeve-shaped rubber bodies, each of which has a fixing portion, a spring portion, and a bearing surface. With four rubber bodies, each groove of a fixing portion surrounds an opening edge in a form-fitting manner.

[0034] Furthermore, a method for mounting a damping device having at least one main part, at least one fastening element for fastening the damping device to a vehicle part, and at least one spring device for connecting the main part to the fastening element in a vibration-capable manner is provided. The method comprises the following method steps: First, the at least one spring device is installed in an opening of the main part or the fastening element, so that the fastening device of the spring device surrounds the fastening means of the main part or the fastening element in a form-fitting manner. Next, at least one section of the fastener or the main part is pressed into the through hole of the spring device until the first support portion of the spring device abuts the first support surface of the main part or the fastener and the second support portion of the spring device abuts the second support surface of the main part or the fastener, or at least one section of the fastener or the main part is inserted into the through hole of the spring device until the first support portion of the spring device abuts the first support surface of the main part or the fastener and the second support portion of the spring device abuts the second support surface of the vehicle part, wherein the damping device is fixed to the vehicle part or an adjacent vehicle part to introduce a preload force into the spring device.

[0050] exist Figures 1 to 3 Detailed Description of the Preferred Embodiments A damping device 10 according to a first embodiment is shown, which serves to absorb and / or damp vibrations of a vehicle part (not shown).

[0051] The damping device 10 comprises a main part 12 , a fastening element 14 for fastening the damping device 10 to a vehicle part (not shown), and at least one spring device 16 which connects the main part 12 to the fastening element 14 in a vibration-capable manner.

[0052] The main body 12 is made of metal and has an approximately cylindrical shape. Figure 2 As seen in FIG, the main body 12 has an opening 18 that extends from a first end 20 of the main body 12 to a second end 22 of the main body 12.

[0053] The main part 12 also has a fastening means 23, which consists of two projections that project into the opening 18 in the region of the ends 20, 22. A trapezoidal recess 26 adjoins the two projections 24, between which a semicircular recess 28 is provided.

[0054] The fastener 14 is designed as a sleeve 30 made of metal or plastic, in particular fiber-reinforced plastic. The sleeve 30 has a central through-hole 32 through which a fastener (not shown) can be guided in order to connect the damping device 10 to a vehicle part (not shown).

[0055] If possible Figure 1 and Figure 2 As can be seen in FIG, the sleeve 30 has a support member 33 approximately in the center, which is designed as a circumferential shoulder 34. The shoulder 34 has a first support surface 36 on the side facing the first end 20 and a second support surface 38 on the side facing the second end 22.

[0056] The spring device 16 is composed of two sleeve-shaped rubber bodies 40a, 40b. Each of the rubber bodies 40a, 40b has a through hole 41, a fixing device 42, a first supporting portion 46a, a second supporting portion 46b and spring portions 44a, 44b connecting the fixing device 42 with the first supporting portion 46a, the second supporting portion 46b.

[0057] The fixing device 42 has fixing portions 43 a and 43 b including circumferential grooves 48 formed in the rubber bodies 40 a and 40 b.

[0058] The spring portions 44a, 44b are arranged obliquely with respect to the longitudinal axis of the damping device 10, so that the spring portions form conically tapering sleeve portions. The axial stiffness of the damping device 10, ie, the stiffness in the axial direction A, is adjusted by the spring portions.

[0059] If you can Figure 3As can be seen in the figure, in the installed state, the first support portion 46a and the second support portion 46b point in opposite axial directions A and are opposite to each other to form a receiving groove 50 for the shoulder 34 of the fastener 14. In the installed state, the contact surface 47 of the first support portion 46a abuts the first support surface 36, and the contact surface 47 of the second support portion 46b abuts the second support surface 38.

[0060] Because the rubber bodies 40a, 40b have a length LF between the fixing portions 43a, 43b and the first and second supporting portions 46a, 46b in the unassembled state, which is greater than the distance AK between the fastening means 23, in particular the projection 24, and the supporting means 33, in particular the shoulder 34, the rubber bodies 40a, 40b are compressed and thereby prestressed when they abut against the first and second supporting surfaces 36, 38. Due to this prestressing, the rubber bodies 40a, 40b exert a pressing force on the first and second supporting surfaces 36, 38, which secures the fastening element 14 between the first and second supporting portions 46a, 46b in a form-fitting and force-locking manner.

[0061] Furthermore, each of the rubber bodies 40a, 40b has an axial stop 52a, 52b, which is designed as a protuberance 54. Figure 1 As shown, a first axial stop 52a is disposed on the top side or first end 20 of the main body 12, and a second axial stop 52b is disposed on the bottom side or second end 22 of the main body 12. The axial stops 52a, 52b cooperate with a flange (not shown) of the sleeve 30 and / or an unshown vehicle portion to limit deflection of the main body 12 in the axial direction A.

[0062] The rubber bodies 40a, 40b also have radial stops 56 that limit deflection of the main part 12 relative to the fastener 14 in the radial direction R. Here, the radial stops 56 are formed by the inner side 58 and the outer side 60 of the rubber bodies 40a, 40b. To limit the deflection in the radial direction R, the inner side 58 abuts against the sleeve 30 and the outer side 60 abuts against the inner wall of the opening 18 in the region of the semicircular recess 28.

[0063] If still Figure 1 As can be seen in FIG, the shoulder 34 and the protrusion 24 form an overlap 61 in the radial direction R at the second end 22. The overlap forms an anti-loss mechanism, which prevents the main body 12 from falling when the rubber bodies 40a, 40b are damaged and accommodates the load that occurs at this time in the event of an accident.

[0064] Below, a possible method for installing Figures 1 to 3 The method of the damping device 10 shown. Figure 2As shown, the rubber bodies 40a, 40b are inserted into the opening 18 so that the groove 48 surrounds the projection 24 in a form-fitting manner, and the first and second bearing surfaces 36, 38 face each other and form a receiving groove 50. Subsequently, the sleeve 30 is inserted into the rubber bodies 40a, 40b by pressing the shoulder 34 into the receiving groove 50. Because the rubber bodies 40a, 40b have a length LF between the fixing portions 43a, 43b and the first and second bearing portions 46a, 46b in the unassembled state, which is greater than the distance AK between the fastening means 23 and the supporting means 33, the two rubber bodies 40a, 40b are compressed, causing the first and second bearing portions 46a, 46b to be preloaded against the first and second bearing surfaces 36, 38. This preload secures the spring device 16 to the main body 12 and the fastening element 14 in a form-fitting and force-fitting manner.

[0065] Further exemplary embodiments of the damping device 10 will be described below, wherein the same reference numerals are used for identical or functionally identical parts.

[0066] exist Figures 4 to 6 , a second embodiment of the damping device 10 is shown, which differs from the first embodiment in that the spring device 16 is formed by a single sleeve-shaped rubber body 64 .

[0067] You can also Figure 5 As can be seen in FIG, the fixing device 42 is composed of a fixing portion 43, which is arranged centrally and has a groove 48 for positively locking around the fastening means 23. A spring portion 44a, 44b protrudes from each fixing portion, which is arranged obliquely with respect to the longitudinal axis of the damping device 10. A first supporting portion 46a and a second supporting portion 46b adjoin the spring portions.

[0068] If still Figures 4 and 5 As can be seen in FIG. 1 , the main part 12 , compared to the first embodiment, has an approximately cylindrical opening 18 with only one projection 24 as a fastening means 23 .

[0069] Furthermore, the fastening element 14 configured in the form of a sleeve 30 differs from the first embodiment in that it has a circumferential first flange 66 a and a second flange 66 b on the end sides, respectively, which form the first support surface 36 and the second support surface 38 .

[0070] In such Figures 4 to 6In the illustrated embodiment, in the unassembled state, the length LF of the rubber member 64 between the fixing portion 43 and the first and second supporting portions 46a, 46b is greater than the distance AK between the fastening mechanism 23 and the first and second flanges 66a, 66b. Consequently, the rubber member 64 is compressed and prestressed when abutting against the first and second flanges 66a, 66b, thereby applying a compressive force to the first and second flanges 66a, 66b, thereby securing the fastener 14 between the first and second supporting portions 46a, 46b in a form-fitting and force-locking manner.

[0071] To install Figures 4 to 6 In the damping device 10 shown, the rubber body 64 is first inserted into the opening 18 of the main body 12 so that the groove 48 surrounds the protrusion 24 in a form-fitting manner. Subsequently, the sleeve 30 is inserted, in particular pressed, into the rubber body 64 until the first flange 66a abuts the first support surface 36 and the second flange 66b abuts the second support surface 38. As a result, the rubber body 64 is preloaded, and the first and second support surfaces 36 and 38 exert a pressing force on the first and second flanges 66a and 66b.

[0072] exist Figure 7 , a third embodiment of the damping device 10 is shown, which differs from the second embodiment in that the sleeve 30 does not include a flange at its end facing the second end 22, so that the second support portion 46b contacts a vehicle part (not shown) when the damping device 10 is installed, and the rubber body 64 is thereby compressed and preloaded.

[0073] exist Figure 8 , a fourth embodiment of the damping device 10 is shown, which differs from the other embodiments in that the supporting mechanism 33 is formed on the main body 12 in the form of a shoulder 34 forming a first supporting surface 36 and a second supporting surface 38, and the fastening mechanism 23 is formed on the sleeve 30 in the form of a protrusion 24 that engages with the groove 48 of the rubber body 40a, 40b in a shape-fitting manner.

[0074] exist Figure 9 , a fifth embodiment of the damping device 10 is shown. This embodiment differs from the first embodiment in that the rubber bodies 40a, 40b have a plurality of radial rubber strips 68a, 68b, which are designed as radially inwardly convex protrusions that protrude into the semicircular recess 28 and contact the main body 12. The radial rubber strips 68a, 68b allow the frequency spread to be adjusted between the radial and axial directions by means of the rigid portion between the rubber bodies 40a, 40b and the radial rubber strips 68a, 68b, which are in the form of additional springs. Thus, the damping device 10 is designed to be rigid in the radial direction R and flexible in the axial direction A.

[0075] exist Figure 10, a sixth embodiment of the damping device 10 is shown, which differs from the fifth embodiment in that radial rubber strips 68 a , 68 b protrude radially in the region of the fastenings 43 a , 43 b and bear against the sleeve 30 .

[0076] exist Figure 11 and Figure 12 , a seventh embodiment of the damping device 10 is shown, which differs from the other embodiments in that the fastening element 14 is designed as a container 70 having a bottom surface 72 and side walls 74, in which the main element 12 is accommodated in a vibration-resistant manner. In order to fix the spring device 16, a plurality of openings 76 are made in the side walls.

[0077] The main part 12 is designed in the form of a cuboid for insertion into a container and has four recesses 78 , wherein a pin 80 projects from each recess 78 .

[0078] In such Figure 11 and Figure 12 In the seventh embodiment shown, the spring device 16 has four sleeve-shaped rubber bodies 40a, 40b, which correspond to the rubber bodies of the first embodiment. The rubber bodies 40a, 40b connect the main body 12 to the container 70 in a vibratory manner. To this end, each rubber body 40a, 40b is inserted into an opening 76 in the side wall 74, so that the groove 48 surrounds the opening edge 82 in a form-fitting manner and the first and second support portions 46a, 46b abut the bottom surface of the recess 78, which serves as the support means 33.

[0079] like Figure 12 As shown, the spring portions 44a, 44b surround the pin 80, so that the pin 80 abuts against the rubber bodies 40a, 40b in the region of the opening edge 82, thereby limiting the deflection of the main body 12 relative to the container 70. In addition, the pin 80 and the opening edge 82 form an anti-loss mechanism that acts in the radial direction R.

[0080] exist Figure 11 and Figure 12 In the illustrated embodiment, in the unmounted state, the length LF of the rubber bodies 40a, 40b between the fixing portion 43 and the first and second supporting portions 46a, 46b is greater than the distance AK between the fastening mechanism 23 and the bottom surface of the recess 78. As a result, the rubber bodies 40a, 40b are compressed and prestressed when abutting against the main body 12, thereby applying a pressing force to the main body 12, which secures the main body 12 between the first and second supporting portions 46a, 46b in a form-fitting and force-fitting manner.

[0081] exist Figure 13, an eighth embodiment of a damping device 10 is shown. This embodiment differs from the first embodiment in that the main body 12 is a vibrating vehicle component 84, such as a pump, compressor, control unit, or powertrain. The damping device 10 isolates and / or damps vibrations of the vehicle component 84. To this end, the damping device 10 is secured to a vehicle portion (not shown) adjacent to the vehicle component 84 by fasteners 14.

[0082] exist Figure 14 , a ninth embodiment of a damping device 10 is shown. This embodiment differs from the second embodiment in that the main body 12 is a vibrating vehicle component 84, such as a pump, compressor, control unit, or powertrain. The damping device 10 isolates and / or damps vibrations of the vehicle component 84. To this end, the damping device 10 is secured to a vehicle portion (not shown) adjacent to the vehicle component 84 via fasteners 14.

[0083] Because of the structural preload between the spring device 16, the main body 12, the fastening member 14, and / or the vehicle portion, the spring device 16 is joined together solely through support, at least on the joining side. Consequently, at least one of the first support portion 46a and the second support portion 46b can only be placed on one of the first support surfaces 36 and the second support surface 38. Furthermore, due to the structural preload, the two first support portions 46a and the second support portions 46b are pressed against the first support surface 36 and the second support surface 38 on both sides, resulting in a two-sided form fit through simple support, thereby securing the spring device 16 to the main body 12 or the fastening member 14. Consequently, the damping device 10 is simple and inexpensive to manufacture.
