Abstract

The invention relates to a hydrodynamic torque converter, comprising: a torsion vibration damper and an axial bearing disposed between a damper component of the torsion vibration damper or a turbine shell of the hydrodynamic torque converter, the turbine shell connected with the damper component, and an adjacent connecting component; and devices for centering the axial bearing in a radial direction. The invention is characterized in that the axial bearing is disposed between two disc shaped components and the centering devices are disposed at least at one of the two disc shaped components.

Claims (4)

1. A hydrodynamic torque converter ( 3 ), comprising: a torsion vibration damper ( 4 ) and an axial bearing ( 2 ) disposed between a damper component ( 4 . 1 ) of the torsion vibration damper ( 4 ) or a turbine shell (T) of the hydrodynamic torque converter ( 3 ), the turbine shell connected with the damper component ( 4 . 1 ), and an adjacent connecting component (F); and devices ( 10 ) for centering the axial bearing in a radial direction, wherein the components ( 4 . 1 , 9 , 18 ) directly supported through the axial bearing ( 2 ) are configured as disc shaped components (S 1 , S 2 ), wherein a centering device ( 11 ) for centering the axial bearing ( 2 ) is configured at least at one of the disc shaped components (S 1 , S 2 );

wherein a particular centering device ( 11 ) includes a centering unit ( 11 . 1 ) configured at the disc shaped component (S 1 , S 2 ) and a centering unit ( 11 . 2 ) configured in a complementary manner at the axial bearing ( 2 );

wherein the centering unit ( 11 . 1 ) configured at the disc shaped component (S 1 , S 2 ) includes a radial support surface ( 27 ) extending over a partial portion of the disc shaped component (S 1 , S 2 ) in a circumferential direction, and the centering unit ( 11 . 2 ) configured at the axial bearing ( 2 ) includes a radial surface ( 28 ) oriented towards the radial support surface ( 27 ) and configured at the axial bearing ( 2 ), and/or the centering unit ( 11 . 1 ) configured at the disc shaped component (S 1 , S 2 ) includes a support surface ( 35 ) oriented in circumferential direction at the disc shaped component (S 1 , S 2 ), and the centering unit ( 11 . 2 ) configured at the axial bearing ( 2 ) includes a surface ( 36 ) oriented towards the support surface ( 35 ) and configured at the axial bearing ( 2 ); and,

wherein the centering unit ( 11 . 1 , 11 . 2 ) formed at the disc shaped component (S 1 , S 2 ) or at the axial bearing ( 2 ) is formed by an axial material deflection ( 20 ), in particular an ear ( 29 ) or a pass through ( 30 ).
