Definitions
- the invention relates to a connecting device for an exhaust-gas turbocharger of the type specified in the preamble of claim 1. Furthermore, the invention relates to an exhaust-gas turbocharger according to the preamble of patent claim 9.
- an exhaust gas turbocharger consists of a plurality of housing sections: a first housing section, which is generally traversed by hot gases, usually exhaust gas of an internal combustion engine, a second housing section, which rotatably mounted in the second housing portion Aufinnbare and between the first housing portion and a third
- Housing portion which is permeated by ambient air in general, is positioned. Between the individual housing sections flange surfaces are formed, such that these flange surfaces are designed to be touched, so that leakage of the hot gas and the ambient air is largely avoided. If there are leaks between the flange surfaces, on the one hand, an overall efficiency of the exhaust gas turbocharger is reduced and, on the other hand, polluting exhaust gases occur between the first housing section and the second housing section, which is particularly to be avoided. It should be noted that the exhaust gas turbocharger should be dismantled, that is, for example, a cohesive connection between the individual flange surfaces could bring about a tightness between the flange surfaces, but then the exhaust gas turbocharger is no longer easy to disassemble and reassemble.
- connection device is different
- the connecting device is usually formed like a tubular clamp, wherein two extending over a circumference of the connecting device elements are connected at their ends facing each other at least on one side releasably connected by means of a screw-nut connection.
- the published patent application DE 10 2014 103 683 A1 discloses a profile clamp whose ends of the elements facing each other in the area of the screw-nut connection are each provided with a nose, such that flange areas of the elements preferably exclusively with the noses have a contact.
- the elements are profiled executed and have flanks, which are designed trapezoidal, since the profile clamp for producing a
- the object of the present invention is a secure connection
- the invention relates to a connection device for an exhaust-gas turbocharger, having a substantially curved first element and a substantially curved second element, the first element having at a first end a radially extending first clamping arm and the second element at a second end opposite the first end End having a radially extending second clamping arm, and wherein a remote from the first end formed third end of the first element opposite to the second end formed fourth end of the second element opposite and is movable therewith.
- the first clamping arm has a first stop facing away from the third end and the second clamping arm has a first stop opposite second stop on.
- the first clamping arm and the second clamping arm can be connected by means of a first connecting element of the connecting device.
- the second end and the fourth end are movably connected to each other by means of a second connecting element.
- Clamping arm facing away from the first end portion with the second element facing away from the second clamping arm second end portion has the movable connection by means of the second connecting element, and wherein at least the first element and / or the second element is formed profiled at least in the region of the second connecting element, and wherein the first element and / or the second element in the region of the second connecting element are formed by this comprehensive.
- the advantage of the invention is that the first element and the second element are shorter, i. can be made shorter in the circumferential direction, as they can stretch due to the elasticity of the transitions. This means that a deformation in particular an extension of the connecting device by
- Heat input which takes place primarily in the contacting with a housing of the exhaust gas turbocharger section of the connecting device, can be reduced, since the elements are designed shortened compared to the prior art.
- a cross section of the transition is formed variable. This means in other words that preferably the cross section of the transition, starting from its end facing the clamping arm to its strongest curvature decreases starting from its strongest curvature up to its receiving portion, which serves to receive the housing of the exhaust gas turbocharger end facing to increase in terms of its cross-section.
- the movable connection by means of the second connecting element leads to an improved and simplified assembly of the connecting device, wherein a further improvement of the assembly can be brought about by carrying out the connection by means of a chain link.
- each element is relatively movable in the direction of three-dimensional space can be added to the chain link and thereby a movement of the two elements relative to each other, for example.
- a compound of the elements with an elastic connecting band is substantially increased.
- the elements are not only profiled in the region of the second connecting element, that is, having a cross-sectional profile, formed.
- an improved overall elasticity of the connecting device can be achieved, which leads to an improved relative adaptation of the connecting device to the housing sections to be connected.
- the connecting device arises in the region of the transitions just as great tensile stress on the inner circumference or compressive stress on the outer circumference that an elastic deformation of the transitions to realize a contact between the attacks is possible. As a result, a uniform distribution of a circumferential stress acting in the elements can be achieved.
- the first clamping arm and the second clamping arm are formed oppositely extending, wherein in the region of the stops a greatest distance between the clamping arms is formed.
- the end portion is bent, the second connecting element formed at least partially encompassing.
- the end portion is executed crane hook-shaped. This leads to a further increase in the resistance moment and thus to a better, in other words more optimized distribution of stresses in the End portions, such that cracks or cracking and bending of the
- the second aspect of the invention relates to an exhaust gas turbocharger, with a first housing section which can be flowed through, in particular by hot exhaust gas, and a second housing section, the first housing section and the second housing section being connected to one another by means of a connecting device.
- the connecting device is designed according to one of claims 1 to 8.
