Abstract

The invention relates to a hydrodynamic coupling. Said coupling comprises a primary wheel (2; 2.2; 2.3) and a secondary wheel (3; 3.2; 3.3), which together form a toroidal working chamber (4; 4.2; 4.3), a shell (5; 5.2; 5.3), which is connected in a rotationally fixed manner to the primary wheel and surrounds the secondary wheel in the axial direction and at least partially in the radial direction, thus forming an intermediate chamber (6; 6.2; 6.3) and at least one passage (8; 8.2; 8.3) that is located in the outer radial area of the shell. The invention is characterised by the following features: a second shell (10; 10.2; 10.3) coupled in a rotationally fixed manner to the first shell and/or the primary wheel, thus forming a second intermediate chamber (11; 11.2; 11.3); the second intermediate chamber is connected to the first intermediate chamber via the passage (13; 13.2; 13.3); at least one passage in the outer radial area of the second shell, the passage or passages in the first shell and the passage or passages of the second shell being offset in relation to one another, when viewed from the peripheral direction.
