Description

The present invention relates to an elastic vibration damper for damping vibrations of a pipe, in particular a fluid-carrying pipe, of a vehicle.

In a motor vehicle, a plurality of lines, in particular fluid-carrying lines, in the form of hoses, pipes and the like is used, such as a line for conducting fuel in order to supply fuel to an internal combustion engine of the motor vehicle. In the operation of a motor vehicle, due to moving components, such as e.g. the internal combustion engine, to vibrations in the engine compartment. The vibrations that occur can be transmitted to lines in the engine compartment and may affect the mechanical properties of the lines. To damp the vibrations damping elements can be attached to the lines. In this case, however, an effective attachment of the damping elements must be ensured on the lines.

The publication EP 1 099 899 A2 describes a hose for holding pipes. This hose is made of a solid material and consists of two different hard components.

It is the object underlying the invention to provide an elastic vibration damper for lines, in particular fluid-carrying lines, in a vehicle, which has advantageous damping properties, and can be effectively attached to the line.

This object is achieved by the subject matter having the features of the independent claim. Advantageous embodiments of the invention are the subject of the figures, the description and the dependent claims.

According to one aspect of the invention, the object is achieved by an elastic vibration damper for damping vibrations of a line, in particular a fluid-carrying line, a vehicle, with an elastic sleeve ring for enclosing the conduit, wherein the elastic sleeve ring has a conduit facing inner wall and an outer wall , wherein in the circumferential direction on the inner wall radially deformable elastic retaining webs are arranged.

By the radially deformable elastic retaining webs on the inner wall of the elastic sleeve ring extending in the circumferential direction of the elastic sleeve ring, an effective support of the conduit can be ensured within the elastic vibration damper and an effective damping of vibrations of the line can be achieved.

In a motor vehicle, a plurality of conduits, in particular fluid-carrying conduits, in the form of hoses, pipes and the like is used, such as e.g. Fuel lines, hydraulic fluid lines or charge air lines to ensure efficient operation of the motor vehicle. During operation of the motor vehicle, movable components, such as e.g. the internal combustion engine, vibrations occur. To vibrationally decouple the leads from the motor housing and thereby prevent the vibrations from being transmitted to the leads, the resilient vibration damper ensures that sufficient damping of vibrations is enabled.

The radially deformable elastic retaining webs can, after the vibration damper has been placed around the line, deform radially outward. Due to the elastic properties of the radially deformable elastic retaining webs, the elastic retaining webs press against an outer surface of the enclosed conduit and allow an effective attachment of the conduit, in particular fluid-carrying conduit, in the elastic vibration damper.

Thus, the radially deformable elastic retaining webs ensure that the elastic vibration damper and the fluid-carrying line are effectively decoupled vibration technology. Depending on the diameter of the enclosed by the elastic vibration damper line, the radially deformable elastic retaining webs can be radially deformed different degrees. Thus, it can be ensured that different lines with different diameters can be enclosed by the elastic vibration damper and can be effectively fixed by the elastic retaining webs. At the same time, an effective damping of vibrations of the lines of different diameters can be ensured.

The elastic vibration damper has a length extending along the longitudinal direction of the pipe. Here, different elastic vibration damper may have different lengths to ensure an effective enclosure of the respective lines at different lines.

In an advantageous embodiment of the elastic vibration damper, the radially deformable elastic retaining webs are curved radially inwardly.

As a result, the technical advantage is achieved that the inward, away from the inner wall of the elastic sleeve ring, directed radial curvature of the radially deformable elastic retaining webs ensures the elastic properties of the elastic retaining webs. As a result, the inwardly curved elastic retaining webs can be effective against the line, in particular on the fluid-carrying line. When enclosing the fluid-carrying line of the elastic vibration damper, the inwardly curved elastic retaining webs can be deformed radially outward, ie be deformed in the direction of the inner wall of the elastic sleeve ring to ensure effective reception of the line.

In a further advantageous embodiment of the elastic vibration damper, the radially deformable elastic retaining webs are attached to both ends of the inner wall, wherein between the inner wall and a central portion of the respective radially deformable elastic retaining web, a gap is limited, in which the respective radially deformable elastic retaining web deformable is.

In a further advantageous embodiment of the elastic vibration damper, the respective radially deformable elastic retaining web has a web thickness, wherein the elastic sleeve ring has a ring thickness, and wherein the ring thickness is greater than the web thickness.

As a result, the technical advantage is achieved that the larger compared to the web thickness of the respective holding web ring thickness of the elastic sleeve ring ensures that a stable elastic vibration damper is obtained. The smaller web thickness of the respective holding web than the ring thickness ensures that the respective holding webs are effectively elastically deformable in order to be in contact with the line accommodated in the elastic vibration damper.

In a further advantageous embodiment of the elastic vibration damper, the radially deformable elastic retaining webs comprise a first retaining web, a second retaining web and a third retaining web, or comprise a first retaining web, a second retaining web, a third retaining web and a fourth retaining web, or comprise a first retaining web, a second retaining web, a third retaining web, a fourth retaining web and a fifth retaining web, or comprise a first retaining web, a second retaining web, a third retaining web, a fourth retaining web, a fifth retaining web and a sixth retaining web, and comprise the radially deformable elastic retaining webs in particular a first retaining web, a second retaining web and a third retaining web.

Thereby, the technical advantage is achieved that the use of three radially deformable elastic retaining webs ensures easy manufacturability of the elastic vibration damper and at the same time allows effective fixation of the line in the elastic vibration damper.
