An axial bearing arrangement formed substantially of two rotating carrier components (1, 2) with circular ring-shaped end faces (3, 4) and an axial anti-friction bearing (5) arranged between the carrier components (1, 2). This axial anti-friction bearing (5) has a first ring-shaped angle disk (6), which rests on the end face (3) of the first carrier component (1) and which is made from a thin steel sheet, and a second ring shaped angle disk (7), which rests on the end face (4) of the second carrier component (2) and a needle cage (10), which rolls between the axial inner sides (8, 9) of the angle disks (6, 7) and which is formed from a plurality of bearing needles (12) arranged adjacent to one another and held at equal distances to one another by a bearing cage (11), and is lubricated and cooled by a lubricant flow (13) emitted by a shaft which passes centrally through the axial anti-friction bearing (5). According to the invention, a circular ring-shaped ramp disk (14), which is designed as a spring, is arranged between the first carrier component (1) and the first angle disk (6), by which ramp disk a radial annual gap (15) between the first carrier component (1) and the first angle disk (6), which results from the axial clearance of the axial anti-friction bearing (5) in the no-load state, can be sealed to prevent a wrong direction of the lubricant flow (13) and the lubricant flow (13) at the same time, can be systematically routed into the inside of the bearing (16) between the angle disks (6, 7). |
