Abstract

A holder ( 3 ) serves for fastening a component ( 2 ), in particular a fuel distributor ( 2 ), onto an internal combustion engine ( 16 ). A holding element ( 9 ) that has a component-side connecting segment ( 10 ) is provided. The holding element ( 9 ) is connectable at the component-side connecting segment ( 10 ) to the component ( 2 ). The holding element ( 9 ) furthermore has a fastening-means-side connecting segment ( 11 ) at which the holding element ( 9 ) is fastenable via a fastening means ( 15 ) onto the internal combustion engine ( 16 ). A receiving part ( 12 ) and a fastening sleeve ( 13 ) are provided. The receiving part ( 12 ) serves to connect the fastening sleeve ( 13 ) to the fastening-means-side connecting segment ( 11 ) of the holding element ( 9 ). The fastening sleeve ( 13 ) has a through opening ( 39 ) through which the fastening means ( 15 ) is guidable. An assemblage ( 1 ) having such a holder ( 3 ) is also described. A connecting method is furthermore described.

First claim

1 - 10 . (canceled)

11 . A holder for fastening a component onto an internal combustion engine, comprising:
a holding element including: a component-side connecting segment at which the holding element is connectable to the component, and a fastening-means-side connecting segment at which the holding element is fastenable via a fastening means onto the internal combustion engine; at least one receiving part; and a fastening sleeve, wherein:
the receiving part serves to connect the fastening sleeve to the fastening-means-side connecting segment of the holding element, and
the fastening sleeve has a through opening through which the fastening means is guidable.

12 . The holder as recited in claim 11 , wherein the component is a fuel distributor.

13 . The holder as recited in claim 11 , further comprising an abutment surface that is configured at least approximately as part of a cylinder enveloping surface is configured on the component-side connecting segment.

14 . The holder as recited in claim 11 , wherein:
an aperture in which the fastening sleeve is placeable is provided on the fastening-means-side connecting segment, and a positioning clearance that enables positioning of the fastening sleeve in at least one of an axial direction of the fastening sleeve and at least one radial direction of the fastening sleeve relative to the fastening-means-side connecting segment, before connection of the fastening sleeve via the receiving part to the fastening-means-side connecting segment, is provided between the fastening sleeve and the aperture.

15 . The holder as recited in claim 14 , wherein the aperture is one of:
configured as a through bore, and open toward one side of the fastening-means-side connecting segment.

16 . The holder as recited in claim 11 , wherein one of:
the receiving part at least one of is configured as a partly annular receiving part and partly surrounds the fastening sleeve circumferentially, and the receiving part is configured as at least one of an annular receiving part and surrounds the fastening sleeve circumferentially.

17 . The holder as recited in claim 11 , further comprising:
a further receiving part that connects the fastening sleeve to the fastening-means-side connecting segment of the holding element, wherein the fastening-means-side connecting segment is disposed, for connection of the fastening sleeve to the fastening-means-side connecting segment, between the receiving part and the further receiving part.

18 . The holder as recited in claim 11 , wherein:
the receiving part has on an outer side an at least partly peripheral cutout, and the fastening-means-side connecting segment engages into the cutout of the receiving part for connection of the fastening sleeve to the fastening-means-side connecting segment.

19 . The holder as recited in claim 11 , wherein:
the fastening sleeve has a fastening segment at which the receiving part is disposed for connection of the fastening sleeve to the fastening-means-side connecting segment, and the fastening sleeve is configured constrictedly, relative to at least one end segment of the fastening sleeve, at the fastening-means-side connecting segment.

20 . An assemblage, comprising:
a component; and at least one holder for fastening the component onto an internal combustion engine, the holder including:
a holding element including:
a component-side connecting segment at which the holding element is connectable to the component, and
a fastening-means-side connecting segment at which the holding element is fastenable via a fastening means onto the internal combustion engine,

at least one receiving part,
a fastening sleeve, wherein:
the receiving part serves to connect the fastening sleeve to the fastening-means-side connecting segment of the holding element,
the fastening sleeve has a through opening through which the fastening means is guidable,
the component includes a base member,
at least one fastening region of an outer side of the base member is configured at least approximately as part of a cylinder enveloping surface, and
the at least one holder is fastened at its component-side connecting segment to the fastening region on the outer side of the base member.

21 . A connecting method for connecting a component that has a tubular base member to at least one holder for fastening a component onto an internal combustion engine, the holder comprising:
a holding element including:
a component-side connecting segment at which the holding element is connectable to the component, and
a fastening-means-side connecting segment at which the holding element is fastenable via a fastening means onto the internal combustion engine;
at least one receiving part; and a fastening sleeve, wherein:
the receiving part serves to connect the fastening sleeve to the fastening-means-side connecting segment of the holding element, and
the fastening sleeve has a through opening through which the fastening means is guidable, the method comprising:
receiving the tubular base member between two receiving tapers; placing the fastening sleeve of the at least one holder on an associated slip-on arbor in such a way that a lower side of the fastening sleeve rests in planar fashion on an alignment surface and slips centeredly onto the slip-on arbor; positioning the receiving part in at least one radial direction on the fastening sleeve; abutting the holding element with its component-side connecting segment against the tubular base member; rotating the holding element around a tube axis of the tubular base member in such a way that a lower side of the fastening-means-side connecting segment of the holding element is parallel to the alignment surface; displacing the at least one receiving part relative to the fastening sleeve, axially with respect to the through opening of the fastening sleeve, in such a way that the at least one receiving part abuts against the fastening-means-side connecting segment; connecting the component-side connecting segment intermaterially to the tubular base member; connecting the receiving part intermaterially to the fastening-means-side connecting segment; and connecting the receiving part being connected intermaterially to the fastening sleeve.
