    专利说明:

    [1] The present invention relates to a device for a hose and / or hose in accordance with claim 1.
    [2] It is possible to connect two free rudder or hose ends or alternatively connect a rudder or hose with a fixed installation with the help of different types of hose and rudder clamps. These hose and pipe clamps are usually designed as a ring formed by a band, which is tensioned around pipes and / or hoses overlapping each other and on the joint formed by these pipes by means of a tightening device such as e.g. a screw. When the screw is tightened, the ring is tightened so that its diameter decreases and creates a clamping action between the hose or pipe clamp and the overlapped and spliced pipes.
    [3] Within the areas where pressurized hose and rudder systems are used for gaseous media, it is advisable to minimize pressure drop due to inert joints between pipes and / or hoses.
    [4] Another area of application where the requirement for tightness has increased between spliced pipes is e.g. in the automotive industry and especially in the category for exhaust and charge air systems. Today's exhaust system has, due to higher environmental requirements, demands to cope with higher pressures and higher temperatures than before, and then higher demands are also made on the tightness between such interconnections of pipes. The higher requirements for tightness thus stem from stricter environmental requirements regarding purity, ie. minor leakage of untreated emissions Iran exhaust systems to the environment, alternatively leakage in the charge air system into the engine.
    [5] A disadvantage of known hose and rudder clamps is that they do not exert a uniform clamping force around the entire circumference of the rudder, but the clamping force from the hose or rudder clamp varies around the periphery of the rudder. This uneven clamping effect means that the part where the pipes are overlapping and interconnected and which is affected by (F10) 2 a lower clamping force from the clamp risks allowing leakage so that the medium inside the pipes is allowed to leach out to the environment, which is not undesirable.
    [6] An object of the present invention is to provide a device at a rudder which better closes around a joint between two overlapping rudders / hoses of prior art devices.
    [7] The invention will now be described, by way of example, with reference to the accompanying drawings, in which:
    [8] FIG. 1 shows an isometric view of a device according to the invention,
    [9] FIG. 2 shows a straight view from the front of the device according to the invention,
    [10] FIG. 3 shows a straight side view of the device according to the invention,
    [11] FIG. 4 shows a straight view from below of the device according to the invention, and
    [12] FIG. Fig. 5 shows a sectional view according to sections A-A, shown in Fig. 2.
    [13] In the following comes a detailed description of the device according to the invention. In the description, legal indications as up, down, At the side will be used and these refer to when the device is arranged with its tightening device arranged straight up as shown in Fig. 2.
    [14] Fig. 1 shows the device according to the invention in an isometric view. The device according to the invention is a hose or pipe clamp for connecting pipes or hoses. The device can also be used for connecting a pipe or a hose with a fixed installation such as e.g. an engine or the like.
    [15] The device comprises an outer ring 1 with a first and a second free spirit 2, 3. The outer ring 1 is challenged in a double material, of which further details later. A tightening device 4 is provided for joining and (F10) 3 tightening the first and second free spirits 2, 3 of the outer ring 1. The outer ring 1 has a tipped portion 12 and is thus not closed, and its geometric shape can be described as circular. circular with a tipped portion.
    [16] An inner ring 5 is arranged on the inside of the outer ring 1, like a liner. The inner ring 5 further has a first and a second part 6, 7. The first part 6 is preferably arranged in the upper part of the outer ring 1 in connection with the tightening device 4, and the second part 7 is preferably arranged in the lower part of the outer ring 1.
    [17] Fig. 2 shows in a straight view from the front of the device, the outer ring 1, the inner ring 5 and its first and second parts 6, 7 and the tightening device 4. At least the first part 6 of the inner ring 5, alternatively both the parts 6 , 7 are designed profiled with a varying profile height, ie. thickness in radial direction. The profile height of the first part 6 of the inner ring 5 increases from its central part 8 in the direction towards its spirits 14, in order to be greatest about 0 in each direction from its central part 8. Thus, a part of the first part 6 of the inner ring 5 has a thinner waist, with a minimal profile height, in its central part 8, in order to then increase the profile height towards its spirits 14. The extension in the width direction of the inner ring 5, i.e. axially, varies depending on the design of the profiling, but is substantially continuous in the direction of propagation of the inner ring 5. In a preferred embodiment, the profiling has the form of two ridges, or axes, which run approximately parallel to the edges of the inner ring.
    [18] The progressively increasing profile height of the first part 6 provides a correspondingly increasing clamping effect around the circumference of the outer ring 1, with the aid of its larger profile height. In those areas where the inner ring 5 has a greater thickness, a higher sealing force is achieved against the hose or pipe, which results in a higher local sealing effect against the hose or pipe than would otherwise have been the case. The largest profile heights are arranged in the areas where the clamping effect without the profiling of the inner ring would otherwise have been lowest. In this way, the clamping effect and the pressure against the pipe along the circumference of the clamp is equalized.
    [19] The first and second part 6, 7 of the inner ring 5 taper off, i.e. has a decreasing profile height, in its breathing areas to form pointed ends 9. This makes it easier for the first and second part 6, 7 to be able to slide about with each other when the tightening device 4 is tightened and reduces the diameter of the outer ring 1 and thus also the inner ring 5 diameter. The design and surface properties have the two parts 6, 7 of the inner ring 5 in relation to each other and in relation to the outer ring 1 tested and adjusted by the person skilled in the art, so that the outer 1 and the inner ring 5 slide easily in relation to each other.
    [20] In the preferred embodiment, the first and second parts 6, 7 of the inner ring 5 are formed as semicircular segments. In an alternative embodiment, the inner ring 5 may be formed as quadrants of a circle segment. Additional alternatives are other divisions, which are adapted to the profiling, and thus achieved clammy effect, which is desirable.
    [21] The part of the inner ring 5 which is progressively designed is preferably arranged symmetrically in relation to the tightening device 4 inside the outer ring 1, as shown in Fig. 2. This symmetrical location is preferred because the clamping force from the device, as mentioned, is usually are lower in the portions where the inner ring 5 has been given a greater profile height. The profile height contributes to an increased clamping force in these areas and thus the clamping force effect along the periphery of the outer ring 1 becomes smoother and thus contributes to a tighter interconnection of the pipes or hoses.
    [22] The first, upper part 6 of the inner ring 5 is fixed in the outer ring 1 at one or more points. Such fastenings can be seen on the outside of the outer ring in Figures 1 and 3. The fastenings can be rivets, welds or fastening by means of flaps in the upper part 6 of the inner ring 5. The flaps are arranged to extend through recesses in the outer ring 1 and are bent. for abutment along it, so that the Owe part 6 is held in place in relation to the outer ring 1 in one area, while it is slid in relation to the outer ring 1 and the lower part 7 of the inner ring 5 in other areas. Other variants of flaps and fastenings are also conceivable for achieving essentially the same function.
    [23] The second part 7 of the inner ring 5 can also be formed with a profiling ring 10, which is shown in Fig. 5. Of the root or hoses which are connected, the inner hose or tube can be made of a firmer material. the outer hose or rudder. When the tightening device contracts the outer ring 1, this means that the softer outer hose or tube will be pushed out into the depression of the profiling between the above-mentioned axes, which produces a sealing effect similar to that of an O-ring, which means that the whole device taken towards the hose or the outside of the rudder. The inner hose or tube of the firmer material thus has the function of an abutment when the tightening device 4 is pulled around the outer softer hose or tube. The profiling 10 for the second part 7 is mainly usable when the force distribution is fairly even in the circumferential direction of the second ring part 7.
    [24] In Figs. 1 and 2 the tightening device 4 is shown arranged between the first and second free spirits 2, 3 of the outer ring 1. On the free spirits 2, 3 of the outer ring 1 there are arranged threaded portions (not shown), which are connected with each other via an elongate device 11 with external passages. The tightening device 4 can also be designed in other ways, such as e.g. a span that spans am heels on each free spirit, (not shown).
    [25] Figures 3 and 4 show the device according to the invention straight from the side and straight from below. In Fig. 4 it is particularly clear that the outer ring 1 is made of a strip, preferably of metal, which is arranged twice around the greater part of the circumference of the outer ring 1. Fig. 4 shows the fixed area 13 where the band of the outer ring 1 is opposite and fastened together by means of welding or riveting. In the preferred embodiment, the fastening also extends through the lower part 7 of the inner ring 5.
    [26] In a special variant, the lower part of the inner ring 5 coincides with the inner layer of the double band in the outer ring 1. Thus, the lower part of the inner layer of the outer ring 1 has been given the above-mentioned profiling, preferably even before the band in the outer ring has been doubled and fastened together as above.
    [27] Because the outer ring 1 is double around most of its circumference, the wall thickness becomes even and the ring 1 also becomes approximately equally rigid along its circumference. This meant that the force when tightening the tightening device 4 is distributed evenly around the clamp.
    [28] The welding directly opposite the tightening device 4 means that the outer band is used to the maximum to apply a pressure to the hose inside the clamp. The friction between the outer and the inner metal band is considerably less than the friction between the clamp and the hose, which mediates minimal force losses in the clamp.
