Description

隔热罩 Heat shield

技术领域 FIELD

[0001 ]本申请涉及一种隔热罩,用于屏蔽热区域,例如,内燃机的热区域。 [0001] The present application relates to a heat shield for shielding heat zone, e.g., the hot zone of the engine. 这样的隔热罩通常包括至少一个金属板层。 Such a heat shield typically includes at least a metal plate layer. 该金属板层减少了热源从其面向热区域的热侧到远离热区域的冷侧所发出热的散发,因而减少了传热。 The metal plate layer reduces the heat emitted from the heat source for the hot side remote from the hot zone to the cold side of the heat distributing zone, thus reducing heat transfer. 此外,这样的隔热罩不仅提供了从隔热罩的热表面到冷表面的传热的减少,而且抑制了从隔热罩的一侧到另一侧的振动的传递。 In addition, such a heat shield is provided not only to reduce the heat shield from the hot surface to the cold surface of the heat transfer, but also suppresses the transmission of vibration from one side of the heat shield to the other side.

背景技术 Background technique

[0002]在其它实施方式中,这样的隔热罩包括至少两个金属板,这两个金属板至少部分地彼此连接,例如,沿着它们的外边缘彼此连接。 [0002] In other embodiments, such heat shield comprises at least two metal plates, these plates is at least partially connected to one another, for example, connected to each other along their outer edges. 例如,通过将一层的边缘围绕另一层的边缘折叠形成一种卷边,可以实现这样的连接。 For example, the edge of the edge layer is folded around another to form a bead, can achieve this connection. 这两个板层这样形成壳体,其中可包含另外的中间层(所谓的方眼网(filet)),例如,作为颗粒或者作为压制件的软材料、纸、纤维羊毛、以及云母、膨胀云母、石墨或膨胀石墨。 The two layers thus formed housing plate, wherein the intermediate layer further comprises (a so-called square mesh (Filet)), for example, as granules or as a pressing member soft material, paper, wool fibers, and mica, expanded mica, or expanded graphite.

[0003]通常,这样的隔热罩或其金属板包括作为通道口的孔,这些孔贯穿至少一个金属板。 [0003] Generally, such a metal plate or a heat shield includes a passage opening of the hole, at least one of these holes through the metal plate. 当安装时,这些孔可使用紧固部件(例如,螺钉),该紧固部件可使隔热罩紧固在内燃机上或紧固在内燃机中。 When installed, these holes may be using a fastening member (e.g., screws), which allows the heat shield fastening member is fastened or secured on an internal combustion engine in an internal combustion engine.

[0004]这些紧固部件通常被附接到相应的部件,例如,内燃机。 [0004] These fastening means are typically attached to the respective components, e.g., an internal combustion engine. 这可使紧固部件将振动和热从该部件传递到隔热罩。 This allows the fastening member and the vibration member to transfer heat from the heat shield. 因此,已经存在多种用于分离从紧固部件到隔热罩传递的热和振动的分离元件。 Thus, there has been more separating element for separating from the fastening member to heat and vibration transmitted to the heat shield. 由编织的线等制成的丝垫等被广泛地用作分离元件。 Wire mats and other like braided wire made is widely used as separating element.

[0005]这样的线编织物一方面非常昂贵,另一方面具有相当大的重量,这是对于轻质金属隔热罩是不利的。 [0005] In one aspect of such a wire weave is very expensive, on the other hand a considerable weight, which for a lightweight metal heat shield is disadvantageous.

[0006]另一缺点是,由于这样的分离元件必须从隔热罩的两侧安装,故这样分离元件的安装麻烦。 [0006] Another disadvantage is that, since such element must be separated, so that it is separated from the heat shield mounted on both sides of the element mounting trouble. 此外,除了隔热罩和紧固部件外,还必须备有分离元件以及在安装地点为技工单独地提供全部这些元件。 Further, in addition to the heat shield and a fastening member, and the separating element must be provided with all of these elements individually at the installation site technician.

[0007]安装这样的分离元件对于技工是另一挑战。 [0007] Such a separating element is mounted for technicians is another challenge.

发明内容 SUMMARY

[0008]因此,本发明的目的在于提供一种成本效益高的、轻质的且易于安装分离元件的隔热罩,该分离元件使隔热罩隔离热和/或振动。 [0008] Accordingly, an object of the present invention is to provide a highly cost-effective, lightweight and easy to install separate heat shield element, the heat shield so that the separating element isolate heat and / or vibration. 本发明的另一主要目的为长期的稳定性和经济效益。 Another main object of the present invention is a long-term stability and economic efficiency.

[0009]通过根据权利要求1的隔热罩来实现该目的。 [0009] This object is achieved by a heat shield according to claim 1. 在从属权利要求中给出了有利的实施方式。 Advantageous embodiments are given in the dependent claims.

[0010]根据本发明的隔热罩主要适用于在内燃机以及其辅助单元中的应用。 [0010] The heat shield of the present invention is mainly applied in the internal combustion engine and the application thereof to the auxiliary unit. 对于设计轻质金属隔热罩是尤其有利的,例如,根据本发明的铝隔热罩。 For the design of a lightweight metal heat shield is particularly advantageous, for example, according to the present invention, aluminum heat shield.

[0011]根据本发明的隔热罩可以以快速且简单的方式安装。 [0011] may be installed in a quick and simple manner according to the heat shield of the present invention. 这也可以限制安装费用。 This can also limit the installation costs. 根据实际情况,可以在将分离元件预安装在隔热罩上或者隔热罩安装期间插入分离元件的实施方式之间选择。 According to the actual situation, you can choose between a pre-installed insertion of the separating element during thermal or heat shield cover mounted embodiment of the separating element. 由于具有预安装的分离元件的根据本发明的隔热罩可以安装隔热罩而无需插入另外的部件、不存在任何元件的变形以及具有极短的周期时间,故该隔热罩是特别有利的。 Since the separating element having a pre-installed without the need for insertion of an additional heat shield member in accordance with the present invention heat shield can be installed, any deformation element is not present and a very short period of time, so that the heat shield is particularly advantageous .

[0012]根据本发明的隔热罩包括至少一个金属板层,该金属板层具有至少一个用于紧固部件的通道口。 [0012] A heat shield according to the present invention comprises at least one layer of a metal plate, the metal plate layer having at least one opening for passage of the fastening member. 根据本发明,分离元件插入该通道口。 According to the present invention, the passage opening separating element is inserted. 分离元件能够至少部分的分离或抑制热和振动从紧固部件到隔热罩的传递。 It can be isolated or suppress transmission of vibration and heat to the heat shield from the fastening member at least part of the separating element. 为了实现这一点,分离元件包括保持元件和夹持元件。 To achieve this, the separation element comprising a holding element and a clamping element. 保持元件搁置在隔热罩的至少一个金属板的一侧上。 At least on one side of a metal plate holding element resting on the heat shield. 为此,保持元件需要定位在用于紧固部件的通道口的区域的外部,因而定位在金属板的区域中。 To this end, the outer retaining member needs to be positioned in the passage opening for the fastening member region, thus positioned in the region of the metal plate. 分离元件还包括夹持元件,该夹持元件贯穿金属板中的孔且搁置在所述金属板的另一表面上,或者如果该夹持元件贯穿多于一个金属板层中的孔,则搁置在所述多于一个金属板层中的最远那个金属板层的另一侧。 Separating element also comprises a clamping element, which clamping element in the through-hole and the metal plate resting on the other surface of the metal plate, if the clamping element or more than one through-hole in the metal plate layer, the rest far more than the other side of the sheet metal plate layer a metal layer.

[0013]这些孔也定位在用于紧固部件的通道口的外部。 [0013] These holes are also positioned outside the opening for the passage of the fastening member. 从定位有保持元件的表面开始,夹持元件贯穿金属板中一个金属板、多个金属板或全部金属板的孔到达隔热罩的所述金属板(夹持元件已经通过的金属板)的另一表面。 From the surface of the holding member positioned started, the clamping member through a hole in the metal plate a metal plate, a metal plate or all of the plurality of sheet metal heat shield reaches the metal plate (metal plate member has passed through the nip) of another surface. 还可以是夹持元件没有贯穿隔热罩的全部金属板而是搁置在两个相邻的金属板之间。 It may also be a metal plate holding all elements but does not penetrate through the heat shield resting between two adjacent metal plates. 这导致分离元件以形状锁定的方式被紧固,且能使分离元件简单安装在隔热罩的通道口中。 This causes the separating element in a form locking manner is fastened, and the separating element can simply mounted in the passage mouth of the heat shield.

[0014]保持元件和夹持元件可通过连接元件连接到分离元件的通道口区域内的中央底座元件,该连接元件相对于通道口径向延伸。 [0014] clamping element and the retaining element may be connected by connecting elements to the central element in the passage opening of the base region of the separating element, the connecting element extends relative to the channel diameter. 因此,保持元件和夹持元件可径向地定位成与分离元件的中央底座元件间隔开距离。 Thus, holding element and the clamping element can be positioned radially central base member is spaced apart from the separating element.

[0015]底座元件有利地布置在各个金属板的通道口内或布置在隔热罩的通道口内。 [0015] The base element is advantageously disposed within the passage opening of each metal plate is arranged within the passage opening or the heat shield. 如果底座元件布置成圆盘形状,尤其布置成与通道口以同心方式存在的圆形元件,则是特别有利的。 If the disc-shaped base elements are arranged, in particular with a passage opening arranged in a concentric circular elements present embodiment, it is particularly advantageous. 优选地,底座元件包括开口,该开口可与隔热罩中的通道口同心布置且允许采用紧固部件。 Preferably, the base member including an opening can be disposed concentrically with the heat shield passage opening and allows the use of a fastening member. 底座元件的外径可小于金属板的通道口的内宽,以允许底座元件完全布置在通道口的区域内。 May be smaller than the outer diameter of the base member is a metal plate passage opening wide to allow base member disposed entirely within the area of ​​the channel opening.

[0016]如果隔热罩具有显著的非对称的振动,离心布置(例如通过椭圆形通道口)是有利的。 [0016] If the heat shield has a significant asymmetric vibration, centrifugal arrangement (e.g., by an elliptical passage opening) is advantageous. 例如,这样的非对称振动可来自不同紧固区域之间的相互作用。 For example, this may be an asymmetric vibration from the interaction between the different fastening region.

[0017]如果底座元件被布置在金属板的通道口内的隔热罩的金属板平面内,则这是尤其有利的。 [0017] If the plane of the metal base plate are arranged the heat shield member within the passage opening of the metal plate, this is particularly advantageous. 因此,径向延伸的连接元件可以以这样的方式弯曲:这些连接元件直接地或间接地过渡到保持元件中,在金属板或者隔热罩的同一表面上的夹持元件也是如此。 Thus, the connecting member may be bent extending radially in such a manner: a transition or connecting elements directly or indirectly to the holding element, the clamping element on the same surface of the metal plate or a heat shield as well. 因此,夹持元件具有一体式曲柄,其允许夹持元件贯穿金属板中的孔或隔热罩中的孔,使得夹持元件的自由端从金属板的另一表面夹持到金属板的最远的表面,其贯穿该孔且导致分离元件与金属板或隔热罩的形状锁定连接。 Thus, a crank integral with the clamping element, the clamping element which allows the through holes in the metal plate or the heat shield aperture so that the free end of the clamping element clamping the metal sheet from the other surface of the metal plate to the most far surface, which leads through the bore and is separated from the metal plate member or the heat shield locking connection.

[0018]由于隔热罩包括多于一层,故有利的是:夹持元件贯穿全部层(包括非金属层),以及夹持元件的自由端搁置在最外层的最远的表面上,这样位于隔热罩的另一表面上。 [0018] Since the heat shield comprises more than one layer, it is advantageous that: the clamping element through all the layers (including non-metal layer), and the free end of the clamping member rests on the surface of the outermost layer furthest, such a heat shield is located on the other surface. 在其它情况下,有利的是:夹持元件仅贯穿一些层(在最极端情况下仅贯穿一个金属层),且夹持元件的自由端搁置在其贯穿的所述层的最远的一个金属板层的另一侧。 In other cases, it is advantageous that: the clamping element only through some of the layers (in the most extreme case only through a metal layer), and the free end of the clamping member rests on a metal layer which is the furthest penetrating the other side of the plate layer. 这意味着夹持元件的贯穿金属层中的孔的部分通过隔热罩的至少一层仍然可以被覆盖。 Portion of the bore through the metal layer which means that the clamping element at least one layer may still be covered by a heat shield.

[0019]为了优化分离效果或抵消隔热罩的强烈的非对称的振动,以非对称方式设计连接元件是有利的。 [0019] In order to optimize or counteract the separation of strongly asymmetrical vibration of the heat shield, asymmetrically designed connecting element is advantageous. 例如,在不同对的相邻连接元件之间可以设置不同的间距。 For example, between different pairs of adjacent connecting elements different pitches may be provided. 以同样的方式,曲柄的高度可以是不同的。 In the same manner, the height of the crank may be different. 此外,连接元件的宽度,尤其在曲柄的区域内的连接元件的宽度可以变化,例如连接元件可包括腰部。 Further, the width of the connecting element, in particular the width of the connecting element in the region of the crank may be varied, for example, the connecting element may comprise a waist.

[0020]此外,对于全部或仅一些保持元件和/或全部或仅一些夹持元件,保持元件和夹持元件可被布置成离通道口具有不同或相同的径向距离。 [0020] In addition, for all or only some of the retaining elements and / or all or only some of the clamping element, the retaining element and the clamping member may be arranged from the channel port having the same or a different radial distance. 对于全部或仅一些保持元件和/或全部或仅一些夹持元件,它们可伸展到相同的周向方向或相反的周向方向。 For all or only some of the retaining elements and / or all or only some of the clamping elements, they may extend to the same circumferential direction or the opposite circumferential direction. 最后,对于全部或仅一些保持元件和/或全部或仅一些夹持元件,保持元件和夹持元件的长度可独立地选择。 Finally, for all or only some of the retaining elements and / or all or only some of the clamping element, the holding element and the clamping element can be independently selected length.

[0021](—方面)保持元件和夹持元件与(另一方面)隔热罩的邻近金属板之间的接触还可通过在保持元件和/或夹持元件的延伸方向上或者在保持元件和/或夹持元件的端部集成的半凸缘(曲柄)或全凸缘而改善。 [0021] (- aspect) and a clamping element holding member (hand) adjacent to the metal contact between the heat shield plate may also be held by the holding member and / or the extending direction of the clamping element or elements integrated end portion and / or the clamping element flange half (crank) or full bead is improved. 这些半凸缘或全凸缘提供保持元件和夹持元件与各自邻近的金属板之间的弹性接触。 These provide a full bead or half bead holding element and the resilient contact between the clamping element and the respective adjacent metal plate. 同时,隔热罩上的分离元件或者紧固有隔热罩的部分之间的接触面积减小,从而导致传热减少。 Meanwhile, the contact area between the separating element is fastened insulated cover or the heat shield portion is reduced, resulting in reduced heat transfer.

[0022]分离元件的具体的优点来自这样的事实:与卡口式连接件相比,该分离元件可以极其简单的方式通过旋入被安装。 [0022] A particular advantage of the fact that the separating element from this: the connecting member as compared with a bayonet, the separating element can be an extremely simple manner be mounted by screwing. 通过定位在保持元件和夹持元件之间过渡处的曲柄,在将隔热罩固定在另一部分上后,分离元件本身不能从通道口松开。 By positioning the crank element at the transition between the holding member and the clamping, after the heat shield secured to the other portion, the separation member can not release itself from the channel port. 因而该设计提供了一种在分离元件和隔热罩的金属板之间特别稳定和可靠的连接。 This design thus provides a particularly stable and reliable separation between the element and the metal plate is connected to the heat shield.

[0023]本发明尤其包括两个可替选的实施方式:当在隔热罩的生产现场安装分离元件时,紧固部件以防松动的方式紧固至隔热罩上;或者当将隔热罩紧固至相邻部分时,分离元件在隔热罩的生产现场进行安装而紧固元件仅仅被插入。 [0023] In particular, the present invention comprises two alternative embodiments: when the separating element is mounted on the production site of the heat shield, to prevent loosening of the fastening member fastened to the insulation cover; or when the insulation when the cover is fastened to the adjacent portions, separating elements are inserted only in the mounting member the heat shield fastened production site. 就后一个实施方式而言,由现有技术已知,可使用螺钉或螺栓作为紧固部件。 On the latter embodiment, it is known from the prior art, can be used as the fastening means of screws or bolts.

[0024]有利地,紧固部件以防松动但仍可移动的方式被布置在分离元件的开口内。 [0024] Advantageously, the fastening member to prevent loosening but still is movably disposed within the opening of the separating element. 尤其优选地,这可以通过利用螺钉作为紧固部件来实现。 Particularly preferably, this may be achieved by using a screw as a fastening member. 以这样的方式,不再需要必须提供负责使用单独的紧固部件来安装隔热罩的技工。 In this manner, no longer need to provide the required fastening member used to install a separate heat shield mechanics. 由于紧固部件与隔热罩和分离元件一起被提供,故紧固部件还可去除技工的负担且可以便利的方式被紧固到该部分上。 Since the fastening member and the heat shield and the separation element are provided together, so that the burden of the fastening member may be removed and may be conveniently mechanic manner is fastened to the upper portion. 该实施方式还防止繁重的单独保存和配置,且还避免了使用不合适的紧固部件的风险。 This embodiment also prevents heavy and configuration are stored separately, and also avoids the risk of improper use of a fastening member.

[0025]优选的使用螺钉作为防松动的紧固部件。 [0025] The fastening member is preferably used as an anti-loosening screws. 螺钉可以以可转动的方式被支撑在通道口内。 Screw may be supported in the passage opening in a rotatable manner. 如果螺钉在开口的通道方向是另外可移动的,则这是有利的。 If the screw in the channel direction of the opening is further movable, this is advantageous. 对于螺钉而言,技工可将隔热罩放置在用于安装的位置,而不存在通过在部件的相反方向上脱落造成螺钉松动的风险。 For screw mechanic heat shield may be placed in a position for mounting without the risk of the member in the opposite direction loss caused by the loosening of the screw. 因此,在螺钉就位之后,通过旋入可立即安装。 Thus, after the screw position, by screwing for immediate installation.

[0026]根据本发明,如果螺钉具有在螺钉的头部和螺纹之间的杆,该杆具有的直径比相邻螺纹小,则螺钉可以以可移动的方式布置在分离元件的开口内。 [0026] According to the present invention, if the screw has a shaft between the head and the screw thread, the stem having a smaller diameter than the adjacent thread, the screw may be movably disposed within the opening of the separating element. 如果直径减小的该区域已经插入到隔热罩或分离元件的相应的狭窄通道口内,则螺钉本身不能从通道口脱落。 If within the region of reduced diameter has been inserted into the heat shield element or separate respective narrow passage opening, the screw itself can not be detached from the channel port.

[0027]在另一有利的实施方式中,螺钉为具有偏置的螺纹螺栓,因而螺纹螺栓具有不同直径的螺纹的两个区域,其仅在将螺栓插入隔热罩后提供有螺钉头部,例如通过旋入。 [0027] In a further advantageous embodiment, the screw having a threaded bolt biased, and thus the threaded bolt has two regions of different diameters of threads, only after which the heat shield is provided with a bolt into a screw head, for example by screwing.

[0028]优选地,以防松动的方式布置的紧固部件通过在螺钉头的方向上预拉伸被布置,例如通过支承在弹簧上。 [0028] Preferably, to prevent loosening of the embodiment is arranged by arranging a fastening member is pretensioned in the direction of the screw head, for example, by a spring supported on. 这样,螺钉向后挤压,依据螺钉的杆的长度的适当选择,这使螺钉没有在其待安装的部分方向上从隔热罩的通道口伸出。 Thus, the screw backward extrusion, suitably selected according to the length of the screw rod, which does not protrude from the screw passage opening in the heat shield to be mounted on a portion of its direction. 在隔热罩安装期间,这防止螺钉朝向将会阻碍隔热罩的确切定位的部分伸出。 During the heat shield installation, which will prevent the screws toward the hinder exact location of the heat shield portion extends. 在定位后,螺钉可固定在该部分中的相应的母螺纹内以克服预拉伸。 Within a corresponding female thread in the positioning screws may be fixed in this portion is to overcome the pretension. 由于弹簧防止螺钉在该部分方向上的重力引起的移动,故如果安装必须水平进行或者从上方进行,则这是特别有利的。 Since the spring force of gravity to prevent movement of the screw in the direction causes the portion, so that if the installation must be level or from above, this is particularly advantageous.

[0029]这样的弹簧提供了在开口内防螺钉松动且可移动安装的另一可行性。 [0029] Such a spring provides a further possibility of screw loosening prevention within the opening and movably mounted. 为此,弹簧可以以形状锁定和/或粘合方式的形式连接至螺钉头和开口或分离元件。 For this purpose, the spring may be in the form-locking and / or adhesively connected to the screw head and the opening or separation element. 弹簧挤压螺钉头,因此整个弹簧轴向远离隔热罩的金属板,但防止螺钉从通道口脱落。 Spring-loaded and screw head axially away from the spring so that the entire sheet metal heat shield, but prevents the screw from coming off the passage opening.

[0030]利用两层或多层的隔热罩,有利的是,金属板中的通道口布置在这样的区域中:在该区域中,在金属板之间没有布置另外的中间层。 [0030] The use of two or more layers of the heat shield, it is advantageous that the metal plate is disposed in the passage opening in such a region: In this region, the metal plate is not disposed between the intermediate layer further. 这使得在安装有隔热罩的部分上隔热罩的极好的压力锁定连接。 This makes great pressure on a portion of the heat shield is attached to the heat shield locking connection.

[0047]与图1中描述的具有常规的分离元件10的常规隔热罩I相比,图2示出根据本发明的分离元件10。 [0047] Conventional heat shield 10 has a conventional separation element depicted in FIG. 1 I compared, Figure 2 shows a separating element 10 according to the present invention. 作为第一元件的该分离元件10包括具有圆形外径的底座元件11。 Examples of the base element separating element 10 comprises a first member 11 having a circular outer diameter. 底座元件11包括开口20,开口20在分离元件的安装状态中被同心地布置在隔热罩I的通道口3内(参见图1)。 The base member 11 comprises an opening 20, opening 20 is arranged concentrically in the heat shield 3 in the I channel port (see FIG. 1) in the mounted state of the separating element. 在图2中,开口10具有六边形形状的外边缘21,这可使分离元件20通过六边形扳手围绕开口20的通道轴线旋转。 In FIG. 2, the outer edge of the opening 10 having a hexagonal shape 21, which allows the separating member 20 about the axis 20 of rotation of the opening passage through a hexagonal wrench.

[0048] 三个径向的臂12a、臂12b和臂12c从底座元件11中分出,各个径向臂绕底座元件11的中间轴线偏置120°。 [0048] The three radial arms 12a, the arm 12b and the arm 12c is separated from the base member 11, each of the radial arm about the axis of the base member intermediate the offset 120 ° 11. 径向的臂12a、臂12b和臂12c从底座元件11在径向方向上延伸。 Radial arms 12a, 12b and an arm 12c 11 arms extending from the base member in the radial direction. 在从底座元件11到臂12a、臂12b和臂12c的各个过渡处,设置有曲柄13a、曲柄13b和曲柄13c。 In the base member 11 to the arm 12a, 12b of each transition arm and the arm 12c is provided from a crank 13a, 13b and the crank of the crank 13c. 在臂12a、臂12b和臂12c的径向边缘处,各个臂12a、臂12b和臂12c分成两个分支14a和16a、两个分支14b和16b、两个分支14c和16c,这些分支全部沿着底座元件11的周向方向延伸。 The arms 12a, 12b and the radial edge of the arm 12c of the arm, each arm 12a, arm 12b and the arm 12c is divided into two branches 14a and 16a, 14b and two branches 16b, 14c and two branches 16c, in all the branches the base member 11 extending in the circumferential direction. 分支14a、分支14b和分支14c充当保持臂,且基本上在曲柄13a、曲柄13b和曲柄13c所限定的平面内延伸,因此在径向延伸的臂12a、臂12b和臂12c的平面内延伸。 Branch 14a, branch 14b, and branch 14c serve as retaining arms, and extending in a plane substantially crank 13a, 13c of the crank and the crank 13b defined, thus radially extending arms 12a, 12b extending within the plane of the arm and the arm 12c. 与其他分支相比,从径向的臂12a、臂12b和臂12c在径向相反的方向上延伸的分支被用作夹持元件16a、夹持元件16b和夹持元件16c。 Compared with the other branches, the radial arms 12a, 12b, and arms 12c branching arms extending in opposite radial directions is used as a clamping element 16a, 16b and the clamping member clamping element 16c. 曲柄17a、曲柄17b和曲柄17c,使夹持元件16a、夹持元件16b和夹持元件16c从连接元件12a、连接元件12b和连接元件12c朝向底座元件11的平面偏置。 Cranks 17a, 17b and the crank of the crank 17c, the gripping elements 16a, 16b and the gripping member gripping member 16c from the connecting element 12a, 12b connecting element and the connecting element 12c facing the base element 11 of the plane offset. 在这些夹持元件16a、16b和16c的自由端,包括另外的曲柄或半凸缘18a、18b和18c,当它们与臂12a、臂12b和臂12c相比时,曲柄18a、曲柄18b和曲柄18c指向与曲柄17a、曲柄17b和曲柄17c相同的方向。 At 16a, 16b and the free ends of the clamping element 16c comprising a crank or an additional half flange 18a, 18b and 18c, which when the arm 12a, arm 12b and the arm 12c when compared to the crank 18a, 18b of the crank and crank point 18c of the crank 17a, 17b and the crank of the crank in the same direction 17c.

[0049]在以下实施例中,隔热罩I本身被示为椭圆形物体。 [0049] In the following examples, the heat shield itself is shown as I elliptical object. 然而,隔热罩可具有多种形状。 However, the heat shield may have various shapes. 所选择的具有其简单形式的椭圆形形状仅用于说明的目的。 The selected oblong shape having its simplest form for purposes of illustration only.

[0050]图3示出分离元件10,该分离元件10被紧固至隔热罩I的金属板层2。 [0050] Figure 3 shows a separating element 10, the separating element 10 is fastened to the heat shield plate metal I layer 2. 隔热罩I包括三个径向延伸且与通道口20同心的孔或缝6a、6b和6c。 I heat shield comprises three radially extending passage opening 20 concentric with holes or slits 6a, 6b and 6c. 在图2中,分离元件10被示出安装在隔热罩I中。 In Figure 2, the separation element 10 is shown mounted in the heat shield I below. 为此,具有夹持臂16a、夹持臂16b和夹持臂16c的分离元件11被定位在金属板层2上的合适位置中,然后顺时针方向转动使夹持臂16a、夹持臂16b和夹持臂16c贯穿缝6a、缝6b和缝6c且接合在金属板层2的另一表面上。 For this purpose, has clamping arms 16a, 16b and the separating element gripping arm 16c of the clamp arm 11 is positioned in place on the metal plate layer 2, and then rotated clockwise so that the clamping arms 16a, 16b clamp arm and a clamping arm 16c through slits 6a, 6b and the slit slits 6c and engage on the other surface of the sheet metal layer 2. 这样,分离元件10牢固地紧固到金属板层2。 Thus, the separating element 10 securely fastened to the sheet metal layer 2. 在示出的实施例中,分离元件主要作用是热分离。 In the illustrated embodiment, the main role of separating element is thermally isolated.

[0051]图4示出另一隔热罩I的俯视图,该隔热罩I包括与图3中的分离元件类似的分离元件10。 [0051] FIG. 4 shows another plan view of the heat shield I, which comprises a heat shield separating element I in FIG. 3 element 10 similar separation. 与图2相比,此处的底座元件11的外径小于金属板层2的通道口3的自由宽度。 Compared with FIG. 2, the outer diameter of the base member 11 here is smaller than the free opening width of the channel plate 2 is a metal layer 3. 因此,分离元件10的底座元件11远离通道口3的外边缘。 Thus, the base member 10 of the separation element away from the channel opening 11 of the outer edge 3. 这进一步改善了在开口20内紧固的紧固部件与金属板层2之间的分离。 This further improves the separation between the opening 20 in a fastening member fastened to the metal sheet layer.

[0052]在图5中示出了与图4的隔热罩相同的隔热罩,然而,垫圈9和具有螺钉头部7的螺钉5已经被定位在底座元件11上。 [0052] FIG. 5 shows the same heat shield of the heat shield of FIG. 4, however, the washer 9 and the screw 5 having a screw head 7 has been positioned on the base member 11. 在该状态下,隔热罩I可被旋入至另一部件,其中关于至少很大程度上的热和振动的传递,该部件和螺钉通过安装在通道口3内的分离元件10与隔热罩I的金属板2分离。 In this state, the heat shield can be screwed into I to another member, on which the transfer of heat and vibration of at least largely, by the screw member and mounted in the passage opening 3 of the separation element 10 and the heat insulation I, separating the metal cover plate 2.

[0053]图6示出与图2示出的分离元件类似的另一分离元件10的俯视图。 [0053] FIG. 6 shows a top view of another separation element and the separation element shown in FIG. 2 is similar to 10. 此处以及在下文两个实施方式中,分离元件没有明确地示出在连接元件12a、连接元件12b和连接元件12c区域中的曲柄13a、曲柄13b和曲柄13c。 In both embodiments herein and hereinafter, the separation elements are not explicitly shown in the crank 12a, 12c and the region of the connecting element 12b connecting element elements 13a, 13b and the crank of the crank 13c. 图6主要目的在于与下文的两个实施方式进行比较。 The main object of FIG. 6 below compares the two embodiments.

[0054]图7示出根据本发明的另一分离元件的俯视图,其具有四个保持臂14a、14b、14c和14d、以及四个夹持臂16a、16b、16(^P16d。 [0054] FIG. 7 shows a top view of another separating device according to the invention, having four holding arms 14a, 14b, 14c and 14d, and the four clamping arms 16a, 16b, 16 (^ P16d.

[0055]与图2和图6相比,在该分离元件10中,保持元件14a、保持元件14b、保持元件14c和保持元件14d的位置与夹持臂16a、夹持臂16b、夹持臂16c和夹持臂16d的位置已经互换。 [0055] Compared with FIG. 2 and FIG. 6, the separating element 10 in the holding member 14a, holding member 14b, 14c and the holding member holding member 14d with the position of the clamp arm 16a, the clamp arm 16b, the clamping arm position of the clamp arm 16c and 16d have been interchanged. 此夕卜,该分离元件10在设计上相似。 Bu this evening, the separating element 10 is similar in design. 仅仅是保持元件14a、保持元件14b、保持元件14c和保持元件14d的端部与夹持臂16a、夹持臂16b、夹持臂16c和夹持臂16d的端部设置有缺口。 Simply holding elements 14a, holding member 14b, 14c and the holding member holding member and the end portion 14d of the clamping arms 16a, the clamp arm 16b, the clamping arm end portion 16c and 16d is provided with a gripping arm notch.

[0056]图8以图8A和图SB示出与图6中的分离元件类似的两个其他的分离元件1。 [0056] FIGS. 8A to FIG. 8 and FIG. SB shows two other separate elements 1 similar to the separating element 6 of FIG. 然而,这两个分离元件示出非对称的设计。 However, the two separate elements shown asymmetrical design.

[0057] 在图8A给出的实施方式中,径向的臂12b设计成与径向的臂12a和臂12c不同。 [0057] In the embodiment of FIG. 8A given embodiment, the radial arms 12b of the arm 12a and is designed to radially different arm 12c. 径向的臂12b示出腰部和凹槽22。 12b shows the radial arms and waist groove 22. 以这种方式,与其他两个臂12a和12c相比,臂12b更柔软且更有弹性。 In this manner, with the other two arms 12a and 12c as compared to the arm 12b softer and more flexible. 此外,该臂12b在与臂12a和臂12c不同的频率范围内进行振动。 In addition, the arm 12b vibrates in the arm 12a and the arm different frequency ranges 12c. 这提供了振动的非对称解耦。 This provides an asymmetrical vibration decoupling. 另外,此处的开口20被设计成圆形开口而不是六边形开口。 Further, the opening 20 is here designed as circular openings rather than a hexagonal opening. 图8A中的分离元件10的保持臂14a、保持臂14b和保持臂14c还可以倾斜的方式进行设计,这导致这些保持臂突出到一方面的夹持臂16a、夹持臂16b和夹持臂16c和另一方面的底座元件11之间的区域中。 Figure 8A separating element holding arm 10 14a, 14b and the holding arm holding arm 14c can also be designed in an inclined manner, which leads to an aspect of the retaining arms projecting clamping arms 16a, 16b clamp arm and clamp arm 16c and the base member 11 on the other hand in the region between.

[0058] 保持臂14a、保持臂14b和保持臂14c的自由端18a、自由端18b和自由端18c还可增大,形成保持臂14a、保持臂14b和保持臂14c的接触面,该接触面一方面被布置成靠近开口20,另一方面提供了这些臂的牢固搁置。 [0058] The holding arms 14a, 14b and a holding arm holding the free end of the arm 14c 18a, 18b and the free ends of the free ends 18c may further increase the retaining arm 14a is formed, and the holding arm 14b holding the contact surfaces of the arms 14c, which contact surface on the one hand is arranged close to the opening 20, on the other hand provides a firm hold of the arms.

[0059]图8B也示出分离元件10的非对称的实施方式。 [0059] FIG. 8B also illustrates an asymmetrical embodiment of the separating element 10. 一方面,此处的开口 20实施为椭圆形孔,其允许紧固部件的非同心插入。 In one aspect, the opening 20 is here embodied as an oblong hole, which allows the fastening member is inserted into the non-concentric. 另一方面,与第三臂12c相比,臂12a和臂12b相对于彼此具有较小的间距,且保持臂14a、14b和14c的长度以及夹持臂16a、16b和16c的长度适用于此因而具有不同的长度。 On the other hand, compared to the third arm 12c, the arm 12a and the arm 12b relative to one another with a smaller spacing, and holding arms 14a, 16a, 16b and 14c and the longitudinal length 14b and 16c of the clamp arm for this thus have different lengths. 这也导致非对称的振动的解耦。 This also results in an asymmetrical vibration decoupling.

[0060]图9示出另一分离元件2,该分离元件在设计上类似于图2中的分离元件。 [0060] FIG. 9 shows a further separate element in the second separating element 2, the separating element is similar in design to FIG. 在图9中,具有杆8的螺钉5另外被布置在分离元件中。 In FIG. 9, 8 having a screw 5 is arranged in a further separate element. 螺钉5的杆8被弹簧25环绕。 8 of the screw rod 5 is surrounded by a spring 25. 该弹簧紧密地附接至螺钉5的头部7或轴环27上。 The spring is closely attached to the head of the screw 5 or 7 of the collar 27. 以相同的方式,弹簧的另一端与分离元件10连接。 In the same manner, the other end of the spring 10 is connected to the separating element. 这样,螺钉5以防松动的方式分别布置在开口3和开口20中。 Thus, a way to prevent loosening the screws 5 are disposed in the opening 3 and the opening 20. 弹簧25附接至螺钉5的头部7使得弹簧本身不能从螺钉5松开,但是螺钉的头部7可相对于弹簧旋转。 Spring 25 is attached to the head of the screw 5, 7 so that the spring itself can not be released from the screw 5, the head of the screw spring 7 with respect to rotation. 因此,可逆着弹簧25的力挤压螺钉5通过通道口3且连续地将螺钉5旋入相邻的部件中。 Thus, the reversible screw pressing force of the spring 25 through the passage opening 3 and 5 successively screw 5 screwed into the adjacent part. 由于弹簧的预拉伸,故无负载状态的螺钉的头部被推动而尽可能远离隔热罩I,使得依据杆8的合适选择的长度,该螺钉5的杆8没有突出超过金属板层2。 Since the pre-tension spring, so the no-load state of the head of the screw is pushed as far as possible away from the heat shield I, suitably selected such that the lever 8 according to the length of the screw rod 5 8 does not protrude beyond the metal plate layer 2 .

[0061]这有助于避免在部件处的定位期间,隔热罩I被卡在该部件的突出部或类似部位,从而阻碍了隔热罩I在部件上的安装。 [0061] This helps avoid during the positioning member at the heat shield I was stuck in the projection portion or the like member, thereby preventing the heat shield member is mounted on I. 在图9中,隔热罩本身未示出以更清晰地提供该图。 In FIG. 9, the heat shield itself is not shown to more clearly provide the FIG.

[0062]图10示出具有旋转对称性的根据本发明的分离元件2的另一实施方式。 [0062] FIG. 10 illustrates another embodiment according to the present invention the separation element 2 with rotational symmetry. 这里,保持元件14a、14b和14c构成连接元件12a、12b和12c的径向三角形附件,其中,连接元件12a、12b和12c分别在三角形的保持元件14a、14b和14c的一个尖端处被连接到保持元件14a、14b和14c。 Here, the holding elements 14a, 14b and 14c constituting the connecting elements 12a, 12b and 12c of triangular radial attachment, wherein the coupling elements 12a, 12b and 12c, respectively, a triangular holding member 14a, 14b and a tip 14c is connected to the holding elements 14a, 14b and 14c. 与上述尖端相邻的尖端然后延伸成夹持元件16a、16b、和16c。 Above the tip adjacent the tip and then extends into the clamping element 16a, 16b, and 16c. 夹持元件16被设计成与先前的实施方式类似。 Clamping element 16 is designed to be similar to the previous embodiment.
