Abstract
A drive assembly, especially for agricultural implements with rotatingly driven masses, has a shear pin coupling (1) with a coupling hub (3) and a coupling sleeve (12) rotatable relative to the coupling hub (3). A ratchet gear (20) supported on the coupling hub (3) and rotatable relative to the coupling hub (3) and the coupling sleeve (12). All three components (3, 12, 20) are connected to one another by the head screw (26) constituting the shear pin. A ratchet (not illustrated) may engage a holding face of the ratchet gear (20). This results in the head screw (26) being sheared. As a result, the coupling sleeve (12) is disconnected from the coupling hub (3) in respect of drive.
