Longitudinal Plunging Unit with Cage Securing Means
First Claim
1. A longitudinal plunging unit for transmitting torque in a shaft assembly, comprising:
- a profiled sleeve with circumferentially distributed, longitudinally extending first ball grooves;
a profiled journal which comprises a first portion with circumferentially distributed, longitudinally extending second ball grooves with ball groove run-outs, and an axially adjoining second portion;
balls which are arranged in groups in pairs of first ball grooves and second ball grooves;
a ball cage arranged radially between the profiled sleeve and the profiled journal and fixing the balls in their axial position relative to one another, wherein the ball cage is displaceable, relative to the profiled journal, between axial stops arranged at a distance from one another; and
an abutment sleeve on the profiled journal and abutting the profiled journal or a component connected thereto to delimit the displacement path of the ball cage towards the second portion.

Abstract
A longitudinal plunging unit comprises a profiled sleeve with longitudinally extending first ball grooves, and a profiled journal with longitudinally extending second ball grooves. The profiled journal engages said profiled sleeve with balls arranged in groups in pairs of first ball groove and second ball grooves. A ball cage positioned between the profiled sleeve and the profiled journal fixes the balls in their axial position relative to one another. The ball cage is displaceable relative to the profiled journal between spaced axial stops. On the profiled journal, there is arranged a stop sleeve, which can abut the profiled journal or a component connected thereto. The stop sleeve delimits the displacement path of the ball cage towards the second portion.
