The invention relates to a vehicle transmission assembly (1) comprising a rolling bearing (3) having a sealing device (10) formed by a first annular diaphragm (11) and a second annular diaphragm (13). The first partition plate (11) is connected with the static bearing outer ring (5), and the second partition plate (13) is connected with the rotary bearing inner ring (4). Wherein first and second L-shaped portions (18, 19) radially outward of the first and second partition plates (11, 13) protrude from the bearing (3) toward the constant velocity joint (2) in the axial direction. The first L-shaped portion 18 has a first and a second annular lip (14, 15) forming a labyrinth seal radial sequence (22, 27, 28) with the second L-shaped portion (19). A third annular sealing lip (16) is located radially downstream of the labyrinth seal radial sequence and cooperates with the second diaphragm (13) by sliding contact. An encoder (20) fitted on the second L-shaped portion (19) has an annular projection (21) forming a first labyrinth seal (22) with the first seal lip (14).
车辆传动总成(1),包含的滚动轴承(3)具有由第一环形隔板(11)和第二环形隔板(13)构成的密封装置(10)。所述第一隔板(11)与静止轴承外圈(5)相连,所述第二隔板(13)与旋转轴承内圈(4)相连。其中,第一和第二隔板(11、13)径向外侧的第一和第二L形部(18、19)在轴向上从轴承(3)突向等速万向节(2)。第一L形部18具有第一和第二环形唇(14、15),与第二L形部(19)之间形成迷宫密封径向序列(22、27、28)。第三环形密封唇(16)在径向上位于所述迷宫密封径向序列的下游,通过滑动接触与第二隔板(13)配合。装配在第二L形部(19)上的编码器(20)具有环形突部(21),与第一密封唇(14)形成第一迷宫密封(22)。
