Abstract

The invention relates to a hydrodynamic torque converter with a housing which comprises a wall which is on the driving side, where a connecting plate is fastened to the housing wall and comprises several mounting locations for connecting the hydrodynamic torque converter to a drive unit, the mounting locations being distributed over the circumference of the connecting plate and in the mounted state of the hydrodynamic torque converter being fastened at corresponding mounting locations of the drive unit. In order to provide a hydrodynamic torque converter which can be produced economically and has a long service lifetime, for each two mounting locations the connecting plate comprises, between them in the circumferential direction, a fastening area with which the connecting plate is fastened to the housing wall which is on the driving side.

Claims (12)

1. A hydrodynamic torque converter comprising:

a housing ( 2 ) having a wall ( 4 ) on a driving side, where a connecting plate ( 5 ) is fastened to the housing wall, wherein the connecting plate ( 5 ) has several mounting locations ( 11 , 12 , 13 ) distributed over a circumference of the connecting plate ( 5 ) for connecting the hydrodynamic torque converter ( 1 ) to a drive unit, wherein in a mounted state the torque converter ( 1 ) is fastened at corresponding mounting locations of the drive unit; and, wherein for each two mounting locations ( 11 , 12 , 13 ) the connecting plate ( 5 ) having a fastening area ( 22 , 32 ) with which the connecting plate ( 5 ) is fastened to the housing wall ( 4 ) on the driving side between the two mounting locations in a circumferential direction, and wherein a connecting annular disk ( 6 ) is connected as one piece to the fastening flange ( 22 , 32 ) by an additional cupping surface ( 30 , 37 ).

2. The hydrodynamic torque converter according to claim 1 , wherein the mounting locations each comprise at least one of the mounting surface ( 11 , 12 , 13 ), the mounting surface being spaced from the housing wall ( 4 ) which is on the driving side and extending radially outwards from a connecting annular disk ( 6 ).

3. The hydrodynamic torque converter according to claim 2 , wherein two preferably oblique cupping surfaces ( 17 , 18 , 19 , 20 ) run out from the mounting surface ( 11 , 12 , 13 ) laterally in the circumferential direction, the cupping surfaces each becoming a fastening flange ( 22 , 32 ) and extending, in the circumferential direction, between the two mounting surfaces ( 11 , 12 , 13 ).

4. The hydrodynamic torque converter according to claim 3 , wherein radially outwards the fastening flange ( 22 , 32 ) is welded to the housing wall ( 4 ) on the driving side.

5. The hydrodynamic torque converter according to claim 3 , wherein the fastening flange ( 22 , 32 ) is connected by rivets to the housing wall ( 4 ) on the driving side.

6. The hydrodynamic torque converter according to claim 2 , wherein the connecting plate ( 6 ) is spaced in the axial direction from the housing wall ( 4 ) on the driving side.

7. The hydrodynamic torque converter according to claim 6 , wherein radially inwards the connecting annular disk ( 6 ) is welded to the housing wall ( 4 ) on the driving side.

8. The hydrodynamic torque converter according to claim 6 , wherein the connecting annular disk ( 6 ) is connected by rivets to the housing wall ( 4 ) on the driving side.

9. The hydrodynamic torque converter according to claim 2 , wherein between the mounting surface ( 11 , 12 , 13 ) and the housing wall ( 4 ), which is on the driving side, a nut is fastened to the connecting plate ( 5 ).

10. A hydrodynamic torque converter comprising:

a housing ( 2 ) having a wall ( 4 ) on a driving side, where a connecting plate ( 5 ) is fastened to the housing wall, wherein the connecting plate ( 5 ) has several mounting locations ( 11 , 12 , 13 ) distributed over a circumference of the connecting plate ( 5 ) for connecting the hydrodynamic torque converter ( 1 ) to a drive unit, wherein in a mounted state the torque converter ( 1 ) is fastened at corresponding mounting locations of the drive unit; and, wherein for each two mounting locations ( 11 , 12 , 13 ) the connecting plate ( 5 ) having a fastening area ( 22 , 32 ) with which the connecting plate ( 5 ) is fastened to the housing wall ( 4 ) on the driving side between the two mounting locations in a circumferential direction, wherein two oblique cupping surfaces ( 17 , 18 , 19 , 20 ) run out from the mounting surface ( 11 , 12 , 13 ) laterally in the circumferential direction, the cupping surfaces each becoming a fastening flange ( 22 , 32 ) and extending, in the circumferential direction, between the two mounting surfaces ( 11 , 12 , 13 ).
