An axial bearing assembly which essentially is formed of two axial rolling bearings (1, 2) between which a circular ring-shaped carrier component (3) is arranged. Each of the axial rolling bearings (1, 2) has a first ring-shaped bearing disk (6, 7) seated against one of the axial sides (4, 5) of the carrier component (3) and a second ring-shaped bearing disk (8, 9) for fastening to additional components of the surrounding construction which are arranged axially on both sides of the carrier component (3) and which each consist of a thin steel plate. A plurality of rolling elements (14, 15) arranged next to each other additionally roll between the axial inner sides (10, 11 and 12, 13) of the bearing discs (6, 7, 8, 9) and are held at a uniform spacing from each other by a respective bearing cage (16, 17) and together therewith form a needle roller and cage assembly (18, 19). Additional recesses (21) are arranged on the inside diameter (20) of the circular ring-shaped carrier component (3), and at the same time the first bearing discs (6, 7) of both axial rolling bearings (1, 2) are interconnected via a centering collar (22) guided through the inside diameter (20) of the carrier component (3) on the one first bearing disk (6), and via outward moldings (24) on the centering collar (22) of the one first bearing disk (6) which are complementary to the recesses (21) on the carrier component (3), and via inward moldings (26) on the inside diameter side (25) of the other first bearing disk (7) which are complementary to the outward moldings (24) on the centering collar (22), in a manner that prevents faulty assembly, and are secured to the carrier component (3) in a captive and rotationally fixed manner. |
