2. The turbocharger according to claim 1, wherein the at least three connections are arranged on a bearing housing of the turbocharger.

3. The turbocharger according to claim 1, wherein at least a first one of the at least three connections has a protrusion beneath which a first flange of the individual flanges of a first of the lines is engageable in the manner of a bayonet lock.

4. The turbocharger according to claim 2, wherein at least a first one of the at least three connections has a protrusion beneath which a first flange of the individual flanges of a first of the lines is engageable in the manner of a bayonet lock.

5. The turbocharger according to claim 3, wherein a thread configured to receive the common screw is provided between a second one of the connections and a third one of the connections.

6. The turbocharger according to claim 4, wherein a thread configured to receive the common screw is provided between a second one of the connections and a third one of the connections.

7. The turbocharger according to claim 5, wherein the first connection and the third connection are designed as water connections for a cooling of the turbocharger, and the second connection is designed as an oil connection for a lubrication of the turbocharger.

8. The turbocharger according to claim 6, wherein the first connection and the third connection are designed as water connections for a cooling of the turbocharger, and the second connection is designed as an oil connection for a lubrication of the turbocharger.

9. The turbocharger according to claim 5, wherein a second of the lines is attached to the second connection and a third of the lines is attached to the third connection, where the second line has a second flange of the individual flanges and the third line has a third flange of the individual flanges, and the second flange and the third flange overlap such that the second line and the third line are held by the common screw on the turbocharger.

10. The turbocharger according to claim 8, wherein a second of the lines is attached to the second connection and a third of the lines is attached to the third connection, where the second line has a second flange of the individual flanges and the third line has a third flange of the individual flanges, and the second flange and the third flange overlap such that the second line and the third line are held by the common screw on the turbocharger.

11. The turbocharger according to claim 9, wherein the first line is attached to the first connection, and the first flange and the second flange are formed such that the first flange is held in a rotationally fixed manner at least by the second flange, so that the bayonet lock of the first line cannot be released for as long as the second line is attached to the second connection.

12. The turbocharger according to claim 10, wherein the first line is attached to the first connection, and the first flange and the second flange are formed such that the first flange is held in a rotationally fixed manner at least by the second flange, so that the bayonet lock of the first line cannot be released for as long as the second line is attached to the second connection.

13. A method for mounting the lines on the turbocharger according to claim 11, the method comprising the following acts of: a) fitting the first line onto the first connection; b) rotating the first line so that the first line is held on the first connection in the manner of a bayonet lock; c) fitting the second line onto the second connection, so that the first flange is held in a rotationally fixed manner by the second flange; d) fitting the third line onto the third connection; and e) tightening of the common screw so that the second line and the third line are held by the common screw.

14. A motor vehicle comprising: at least one turbocharger according to claim 1.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) FIG. 1 is a schematic representation of a motor vehicle with a turbocharger.

(2) FIG. 2 is a top view of the turbocharger of FIG. 1.

DETAILED DESCRIPTION OF THE DRAWINGS

(3) FIG. 1 shows a motor vehicle 1 with a turbocharger 2 for an internal combustion engine (not shown). Attached to a bearing housing 3 of the turbocharger 2 are a first line 7, a second line 8 and a third line 9. Cooling water for the cooling can be conducted via the first line 7 and the third line 9 through the turbocharger 2. Oil for the mounting of a drive shaft (not shown) can be supplied via the second line 8 to the turbocharger 2.

(4) FIG. 2 shows a top view of a portion of the turbocharger 2 of FIG. 1. In particular, the bearing housing 3 of the turbocharger 2 can be seen. On the depicted side of the bearing housing 3 are arranged a first connection 4, a second connection 5 and a third connection 6. The first line 7 is attached to the first connection 4. A first flange 10 of the first line 7 engages beneath a protrusion 14 of the first connection 4 in the manner of a bayonet lock. The second line 8 has a second flange 11. The third line 9 has a third flange 12. The second flange 11 and the third flange 12 overlap such that the second line 8 and the third line 9 are held by a common screw 13 on the turbocharger 2. A thread for the common screw 13 is provided between the second connection 5 and the third connection 6.

(5) The first flange 10 and the second flange 11 are formed such that the first flange 10 is held in a rotationally fixed manner at least by the second flange 11, so that the bayonet lock of the first line 7 cannot be released for as long as the second line 8 is attached to the second connection 5.

(6) The first connection 4 and the third connection 6 are designed as water connections 15 for a cooling of the turbocharger 2. The second connection 5 is designed as an oil connection 16 for a lubrication of the turbocharger 2.
