| 摘要 |
A longitudinal plunging unit for a shaft assembly used for torque transmitting purposes. The unit includes a profiled sleeve (11) with circumferentially distributed, longitudinally extending first ball grooves (12), a profiled journal (21) with circumferentially distributed, longitudinally extending second ball grooves (22), balls (31, 32, 33) which are arranged in groups of balls in pairs of first and second ball grooves (11, 21), and a ball cage (41) which is positioned between the profiled sleeve (11) and the profiled journal (21) and axially fixes the balls in their positions relative to one another, wherein in the region of the ball grooves (12, 22), the profiled sleeve (11) and the profiled journal (21) include the same torsional stiffness, such that, during the introduction of torque, they are subject to the same angles of torsion.
