  • Patent number: 9689431
    Abstract: A seal arrangement (1) of an anti-friction bearing, which seal arrangement (1) is inserted between a first bearing part (2) and a second bearing part (4). The seal arrangement includes a seal (6) which is positioned on the rotationally fixed first bearing part by a support element (15) which is enclosed at least on one side by an elastic seal material (16), and which seal (6) includes at least one sealing lip (25, 26). A thrower ring (7), forming a collection chamber (13), of the seal arrangement is assigned to the second rotatable bearing part. To this end, a cylindrical portion (9) of the thrower ring is snapped in an end-side circumferential groove (11) by a flange (5) of the second rotatable bearing part. A radial leg (12) of the thrower ring extends such that it maintains a sealing gap (14) to the seat. Moreover, the seal of the seal arrangement includes elastic sealing lips which are supported on the second bearing part such that they are offset with respect to the thrower ring.

  • Patent number: 8403121
    Abstract: A device for sealing a double clutch transmission of a motor vehicle, with a transmission housing, in which are arranged a clutch chamber with clutch oil and a double clutch, a transmission chamber with transmission oil and a double clutch transmission wheel set and two co-axial drive shafts disposed, one inside the other. One drive shaft is an interior central shaft which extends inside the transmission chamber from the end of the second hollow drive shaft. The two drive shafts each have a sealing element to seal the clutch chamber from the transmission chamber. A mounting component is situated inside and fixed to the transmission housing to support two adjacent sealing elements. A first sealing element forms a seal radially on the hollow drive shaft and a second sealing element forms a seal radially on the central drive shaft to provide a reliable seal and offer a simple ventilation and leakage detection.
