Abstract: A rolling boot that has improved stability especially at increased rotational speeds comprises a first fastening region, a second fastening region, a transition region adjacent to the first fastening region, as well as a diaphragm region adjoining the transition region, and at least on peripheral reinforcement fin is arranged on an external side of the transition region.

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.

Abstract: A longitudinal plunging unit for the transmission of torque in a drive assembly. It comprises a profiled sleeve (21) with circumferentially distributed, longitudinally extending first ball grooves (22); a profiled journal (11) with circumferentially distributed, longitudinally extending second ball grooves (12); balls (31) which are arranged in groups of pairs of first and second ball grooves (12, 22); a ball cage (41) which is arranged between the profiled sleeve (21) and the profiled journal (11) and fixes the balls (31) in their positions relative to one another; and a spring mechanism (51) which is supported on at least one axial stop (42, 43) and designed in such a way that, in an unloaded condition, the ball cage (42) is held at a distance from the at least one axial stop (42, 43).
