<p>The assembly (1) for controlling the clutch (5) of a forestry winch consists of coaxially designed mutually insertable and sealed parts (11, 12) with an adequate cavity with supply (123) of the hydraulic media in-between by which the parts (11, 12) can be shifted in the axial direction one against the other. In this position the fixed internal part (11) is supported by the enclosure (2) or at least a part of it, while thanks to the hydraulic media and against the force of spring (7) or thanks to the latter, the moving external part (12) is either directly or indirectly pushed towards the drum (4). The friction linings (51, 52) of the clutch (5) are located on a chain-wheel (6) and drum (4), which can be freely rotated after activation of the clutch (5) on axis (3) together with the chain-wheel (6). This way a simple and low- cost while at the same time reliably operating control assembly (1) is provided, meaning for activating and deactivating of the clutch (5) which enables the control of the clutch (5) by way of a hydraulic circuit made available on the winch.</p> |
