Joint element with a swing-damping brake， joint assembly comprising the joint element， and machine comprising the joint assembly

A hinge element provided with a vibration damping brake， comprising a first hinge part (2)， a second hinge part (4) and a vibration damping brake. The second articulation portion (4) comprises a first end portion (41) mounted on the first articulation portion (2) for pivoting about a pivot axis via a bearing assembly (3). The vibration damping brake is adapted to dampen the oscillation between the first articulation part (2) and the second articulation part (4) about the axis of rotation， the vibration damping brake comprising at least one first brake disc member (52) and at least one second brake disc member (54). The second hinge portion (4) comprises a second end portion (42) releasably connected to the first end portion (41) by a hinge portion joint adapted to transmit torque between the first end portion (41) and the second end portion (42)， and the hinge portion joint adapted to allow the second end portion (42) ) in the axially disengaged position relative to the first end portion (41)， the disengaged position allowing the active components of the shock absorber brake to be replaced while the first end portion (41) remains mounted on the first articulated portion (2)， the active components of the shock absorber brake comprising at least one first brake disc member (52) and at least one second brake disc member (54).
