Abstract
A seal retainer device for fixing the position of at least one sealing device, comprising at least one contact surface for fixing the position of a seal in the radial and/or axial direction, a first functional surface for linking to a component, and at least one second functional surface to form an axial or radial bearing sliding surface. In addition, the invention relates to a power transmission unit having a seal retainer that holds seals for sealing off two pressure chambers.
Claims23
A seal retainer device (1) for fixing the position of at least one sealing device (9, 10) between a component (4) and at least one connecting element (7, 8), for sealing two pressure chambers (2, 3) from each other in a power transmission unit (31), comprising at least one contact surface (22, 23) for fixing the position of a sealing device (9, 10) in the radial and/or axial direction, at least one first functional surface (70, 71) for coupling with a component (4) and at least one second functional surface (28) to form a bearing surface, in particular an axial or radial sliding bearing surface.
A power transmission unit (31) for connecting between a drive engine and a transmission input shaft (32), which participates with two other connecting elements (7, 8) in forming two pressure chambers (2, 3), there being sealing devices (9, 10) between the hub (38) and the respective connecting element (7, 8), wherein the individual sealing devices (9, 10) between the hub (38) and the connecting elements (7, 8) are fixed in their position with respect to the hub (38) and the connecting elements (7, 8) in the axial and/or radial direction by means of a seal retainer device (1), and the seal retainer device (1) is situated on the hub (38).
