JOINT ELEMENT PROVIDED WITH SWING DAMPENER BRAKE， JOINT ASSEMBLY COMPRISING THE JOINT ELEMENT， AND MACHINE COMPRISING THE JOINT ASSEMBLY

A joint element provided with a swing dampener brake and comprising a first joint part (2)， a second joint part (4)， and the swing dampener brake. The second joint part (4) comprises a first end part (41) and a second end part (42) which is detachably fixed to the first end part (41) by a joint part coupling which is adapted to transfer torque between the first end part (41) and the second end part (42)， and the joint part coupling is adapted to allow the second end part (42) to be moved in an axial direction to a detached position in relation to the first end part (41)， the detached position allowing the replacement of active components of the swing dampener brake while the first end part (41) remains bearing- mounted to the first joint part (2).
