In an alternative embodiment, the oscillation brake comprises at least one first brake disc member, and at least N 35 one second brake disc member.
    The bearing assembly 3 is located radially outside the sleeve hole of the sleeve portion 26, and thus also outside the second brake disc members 54 of the first brake disc members 52. The bearing assembly 3 comprises a plain bearing, and is adapted to receive both radial and axial loads. The radial direction is perpendicular to the axis of rotation. In alternative embodiments, the bearing assembly may comprise a ball bearing or a roller bearing. The vibration damping brake actuation system is adapted to provide axial forces to press the active surface of each first brake disc member 52 against the active surface of the adjacent second brake disc member 54, thereby providing an active surface of each first joint of the first brake disc member 52 and adjacent second brake member. 2 and the second joint part 4.

    The second end portion 42 is adapted to be moved relative to the first end portion 41 between the drive station shown in Figure 1 and the detached station shown in Figure 2. From the situation of Fig. 1, the situation of Fig. 2 is reached by moving the second end portion 42 in the axial direction relative to the first end portion 41.
    In Figure 2, each of the first brake disc member 52 and each of the second brake disc member 54 is located in the axial direction outside the sleeve portion 26. The detached position of the second end portion 42 allows the active components of the vibration damping brake to be serviced and replaced while the first end portion 41 remains mounted on the first articulation 2.
