Description

Technical Field

[0001] The present invention relates in particular to functional elements used in motor vehicles, in particular to block devices for damping devices and / or separating devices, in which a free space for the functional elements and / or the damping or separating device is provided.

Background Art

[0002] In the prior art, for example, in order to prevent vibrations from spreading inside a motor vehicle, functional elements and / or damping or separating devices therefor are used inside the motor vehicle, and the functional elements therefor are used between the vehicle body and the vibrating engine part or other parts inside the vehicle that are prone to vibration, and / or in relation to other areas inside the motor vehicle.

[0003] For example, International Publication No. 2020 / 001872 (Patent Document 1) discloses a vibration damping mechanism in which, for example, an engine and / or a compressor are held inside a link mechanism. The engine and / or the compressor naturally cause vibrations during operation, which can particularly interfere with the vehicle occupants. Therefore, an elastic element is provided in the joint structure within the mechanism, and this elastic element is connected to the vehicle body via an elastomer. The elastomer separates the vehicle body from the compressor as much as possible, that is, it dampens the vibrations emitted from the engine and / or the compressor. The damping and / or separating device proposed in Patent Document 1 consists of various components that must be joined and assembled within a suitable opening of the vibration damping mechanism. Both the necessary pre-assembly and the final assembly are relatively complex and accordingly costly.

Summary of the Invention

Problems to be Solved by the Invention

[0005] The object of the present invention is to provide a block device that offers the advantage of pre-assembling functional elements such as vibration damping devices and / or isolation devices in a designated installation space, preferably an automobile, and then reliably placing them in the final location. [Means for solving the problem]

[0006] According to the present invention, a blocking device for a functional element, in particular a damping device and / or a separation device, is proposed, the device having a predetermined free space for the functional element, provided with a blocking extension, the extension comprising at least one, preferably two, retaining parts extending perpendicular to the cylindrical axis of the functional element and along the cylindrical axis, and provided with at least one accumulation of material for fixing the functional element to a designated installation space provided in the automobile, the fixing being, for example, clamping, and either press-fit or mating connections may further be considered.

[0007] The holding portion is, advantageously, a strut (a slender member) provided in the direction of the cylindrical axis of the block device.

[0008] The material aggregate can be manufactured from polymer materials with excellent coefficient of friction and permanent elastic properties, such as rubber, and can be particularly injected.

[0009] The blocking extension, which extends perpendicularly to the cylindrical shaft, is advantageously provided according to the installation space within the vehicle. The blocking extension may also be a cover. Furthermore, the blocking extension may be star-shaped, elliptical, or other shapes, as long as the area of ​​the blocking extension can fix the functional element in a predetermined installation space.

[0010] Furthermore, the blocking extension must be connected to the functional elements so that the free space provided for separating the functional elements before and after final assembly can be restricted in a prescribed manner. This is achieved by a gap between the blocking extension and the functional elements, created by the accumulation of material. This gap defines the maximum deflection, displacement, and vibration of both the block device itself and the functional elements in the cylindrical axis direction, as enabled by the present invention.

[0011] The present invention can be used advantageously and cost-effectively in any rotationally symmetric functional element and its installation space.

[0012] At least one assembly for securing a functional element to a corresponding installation space within the vehicle is designed to securely fix the functional element, for example, by clamping, in relation to pre-assembly and final positioning in the installation space. The material assembly preferably acts near the cylindrical axis in the overall arrangement with respect to the functional element for retention. Alternatively, the material assembly may latch a block device to the functional element. Other press-fit or mating connections may be used.

[0013] The blocking extension is advantageously connected to the functional element at a distance, i.e., with a gap, in the direction of the cylindrical axis in the overall arrangement, in order to limit the movement and / or vibration of the functional element. This prevents extreme movement of the functional element and / or damping and / or separating device, which are equipped with damping and / or separating parts of permanent elastic elastomer, and prevents the elastomer part from being subjected to excessive load and rapidly deteriorating. This extends the service life of the functional element.

[0014] In a preferred embodiment of the block device according to the present invention, two blocking extensions are provided facing each other in the cylindrical axis direction, with a material accumulation between them provided on the inner circumferential edge of a holding portion which may be a blocking extension and / or strut (elongated member). Here, a functional element, in particular a damping device and / or a separation device, is held between two plate-like and / or mushroom-shaped blocking extensions, and the plate-like and / or mushroom-shaped blocking extensions create a distance and / or gap between the functional element and the surfaces assigned to each of the blocking extensions on both sides. Thus, the maximum deflection of the functional element is defined. [Effects of the Invention]

[0015] Functional elements can be pre-assembled using material aggregates on corresponding forms of block devices according to the present invention, and as a result, functional elements, in particular damping devices and / or decoupling devices, can be securely and permanently coupled and / or mated even before final assembly. Furthermore, the aggregates of two materials that support the corresponding components together and generate a holding force, such as a pinching force, also ensure that the functional elements are securely fixed in place for the entire lifespan of the block device and functional elements, in particular damping devices and / or decoupling devices according to the present invention.

[0016] To secure functional elements in place, adhesives may be used instead of applying a holding force, particularly a clamping force, through the accumulation of materials. Other fastening methods are also known to those skilled in the art, such as latch connections with shapes corresponding to the components being connected.

[0017] The present invention will be described in more detail below with reference to preferred embodiments based on the drawings, but since the same reference numerals in different drawings and embodiments indicate the same components, there is no need to explain them again. [Brief explanation of the drawing]

Mode for Carrying Out the Invention

[0019] Figure 1a is a side view of a block device 100 according to the present invention. The block device 100 has a blocking extension 10 which is a cover and / or plate. Stabilizing struts (elongated members for stabilization) 10a are for providing the cover and / or plate 10 with as little material as possible and with sufficient stability. Two retaining parts 12, which are provided as struts (elongated members) 12 in this case, extend from the cover and / or plate 10. As can be seen from Figure 1b, a passage opening 16 for connecting members (not shown), such as retaining bolts, extends rotationally symmetrically about the cylindrical axis Z. The passage opening 16 has an anti-torsion retaining projection 14, which provides a retaining area such as a clamping area from which a functional element 22, such as a damping device and / or separation device 22, can be fixed in place. The assembly 14 can be molded from, for example, rubber, e.g., injection molded. Various plastics may also be considered for this purpose. As shown in the illustration, the passage opening 16 is not circular, but rather has a non-circular contour in this embodiment, in order to accommodate and hold, for example, a sleeve 18 with a corresponding non-circular cross-section, particularly in a fixed state so as not to rotate. The corresponding sleeve 18 may or may not consist of a structure for holding a stud bolt, such as an internal thread.

[0020] The perspective view in Figure 1c particularly shows the strut (elongated member) fixing projection 14a, which on the one hand provides a sleeve 18 of the corresponding shape (see Figures 4 and 5), and on the other hand can fix the functional element 22, in particular the damping device and / or separation device 22, in a predetermined position. Hereafter, the functional element 22 will be referred to as the separation device, but it may also be referred to as the damping device.

[0021] As illustrated, the separation device 22 is fixed to the block device 100 of the present invention by the accumulation of material of the anti-twist holding projection 14 and / or strut (elongated member) fixing projection 14a that provide the clamping area. Conversely, pre-assembly and final post-assembly positioning of the functional elements can also be simplified by using adhesive instead of the clamping area.

[0022] In the embodiment shown in Figures 2a-2c, two block extensions 10 are provided, each in which two retaining parts and / or struts (elongated members) 12 are in contact with each other in the Z-direction of the cylindrical axis. The damping device 22 can be housed between the two covers 10, thereby being held in place by the accumulation of corresponding materials, for example, by clamping force, for pre-assembly and final fixing. The struts (elongated members) 12 themselves may but do not need to be in contact with each other adjacent to each other, because each of the upper and lower covers 10 is held by a retaining force to a separation device 22 (not shown here), and is firmly held through the separation device 22 (not shown here), for example, by clamping force.

[0023] As can be seen from the figure, both block devices 100 extend along the cylindrical axis Z, and the cover 10 spreads out in the XY plane. Each direction is common to all the embodiments shown.

[0024] The clamping region 14, in particular the anti-twist holding projection 14 that provides the clamping effect, and the strut (elongated member) fixing projection 14a are clearly shown in Figure 2c.

[0025] Figures 3a and 3b show the damping device 22 in addition to the components of the block device 100 according to the present invention. A gap 20 is provided between the separator 22 and each cover 10 of the block device 100 relative to each end face of the separator 22, which helps to define the maximum deflection of the separator 22 during operation and to limit the load on the separator 22. Thus, the damping device 22 having an elastomer portion is not subjected to excessive load and, therefore, premature deterioration can be avoided. A sleeve 18 for acoustically isolating the vibrating part of the vehicle from the rest of the vehicle is provided within the separator 22 in a passage opening 16 for a connecting element, through which a retaining bolt (not shown) can be inserted.

[0026] The specific shape of the separation device 22 is not important in this invention.

[0027] As can be seen from the figure, the sleeve 18 has an outer flat region 18a that corresponds to the shape of the passage opening 16. This allows the strut (elongated member) 12 to act as a fixed mechanical bracket for the sleeve 18 on the one hand, and to fix the sleeve 18 in a twisted direction so that it does not rotate within the passage opening 16 on the other hand. The separation device 22 is pressed against the block device 100 according to the present invention by the twist-preventing holding projection 14, which can also be called the clamping region 14.

[0028] The separation device 22 is described in more detail in Figure 4, and in principle, the separation device 22 can be provided in any form, as long as it is suitable for the vibrations to be damped and the available installation space.

[0029] The separation device 22 has an outer connector sleeve 24 and an inner connector sleeve 24a. Between these two sleeves 24, 24a, there is a permanent elastic elastomer portion 26 that provides a damping function. In the clamping region 14 provided in the direction of the cylindrical axis Z, the accumulation of material provided in the area of ​​the cover and / or the area of ​​the strut (elongated member) 12 holds and clamps the separation device 22.

[0030] In this case as well, the gap 20 restricts the deformation of the permanent elastic elastomer portion 26 in the Z-axis direction.

[0031] Figure 5 shows another embodiment of the present invention and should be referred to in addition to the components already described. Here, retaining bolts (not shown) that can be inserted through the free cross-section of the passage opening 16 can hold a vibrating component to be separated, such as a compressor or engine, to the vehicle body (not shown), and the separation device 22 absorbs vibrations, noise, etc., emitted from the mechanical component to be held, such as the compressor. The block device 100 according to the present invention also in this case consists of two covers 10 and two struts (elongated members) 12 (not shown in the figure) on each, which fix the separation device both in pre-assembly and in the final position, preferably by clamping force.

[0032] In summary, the block device 100 according to the present invention can fix the separation device 22 in place and, in particular, limit the maximum allowable load acting upon it. The components of the block device 100 according to the present invention can be easily manufactured from plastic. Common materials such as polypropylene, polyethylene, and polyamide can be used for the block device 100. Such plastics are durable, mechanically stable, and inexpensive to process. Of course, a metal block device 100 may be manufactured using metal, at a higher cost. [Explanation of symbols]
