Rapid-release safety coupling

摘要

The drive line is divided into at least two axial sections (I,II) which move axially but not able to rotate in relation to each other. Between the two sections, a power unit (13,12,4) allows for movement only when a set amount of axial force has been exceeded. One of the two sections operates the release mechanism (25) for relieving the annular chamber (6) in the case of axial movement.A second release mechanism (23) also possessing the annular chamber is relieved by the relative movement between the sleeve (4) and the surface of an element of the first and or second machine part. The annular chamber is connected to a duct arrangement part. The annular chamber is connected to a duct arrangement (22,26).
