Controlled axial biasing unit

摘要

A controlled axial biasing unit (1) is provided which substantially includes a first ramp disk (11) and a second ramp disk (12), each of which disks is configured with a plurality of ramp contours (8). An annular cage (2) that carries a plurality of rolling elements (3) is inserted between the first ramp disk (11) and the second ramp disk (12). At least the first ramp disk (11), the second ramp disk (12) and the cage (2) are made by a shaping method without chip removal. Each of the first ramp disk (11) and the second ramp disk (12) is configured with a continuous wall (32). Likewise through this shaping method, the first ramp disk (11) and the second ramp disk (12) have on an outer periphery (UA) an integrally formed safety stop device (14) for respective end positions.
