Abstract
A coupling arrangement, particularly for a hydrodynamic coupling device, including a first friction surface arrangement that is rotatable around an axis of rotation with a housing filled with fluid, a second friction surface arrangement, which is rotatable around the axis of rotation with a driven member, and a pressing arrangement that is actuated by pressure fluid. The first friction surface arrangement and the second friction surface arrangement are brought into frictional engagement by the pressing arrangement. The pressing arrangement includes an annular piston element that is movable in its radial inner area in a fluid-tight manner in direction of the axis of rotation on a guide disk element which is secured to an inner side of the housing.
Claims15
A coupling arrangement for a hydrodynamic coupling device, comprising:
- a first friction surface arrangement configured to be rotatable around a first axis of rotation;
- a housing configured to be filled with fluid, the housing being rotatable with the first friction surface arrangement about the first axis of rotation;
- a second friction surface arrangement configured to be rotatable around the first axis of rotation;
- a driven member coupled to the first friction surface arrangement the driven member being rotatable about the first axis of rotation with the second friction surface arrangement;
- and
- a pressing arrangement actuatable by a pressure fluid, the pressing arrangement configured to bring the first friction surface arrangement and the second friction surface arrangement into frictional engagement, the pressing arrangement comprises:
- a guide disk element secured to an inner side of the housing;
- and
- an annular piston element configured for movement in its radial inner area in a fluid-tight manner in a direction of the axis of rotation on the guide disk element.
