The clutches in milling machines must be capable of transmitting their high power output and reliably connecting and disconnecting the power in the milling power train. WIRTGEN clutches were designed for use in the respective power train. They are optimised to handle the stresses generated by the dynamic action of the cutting process. Disks and gear rim should always be replaced together. The pressure springs require changing within the set.

1 Precisely fitting manufacturing of the disk teeth that permits easy movement in their guides and thereby allows for low-loss operation.

2 The sturdy thrust washer for pretensioning is supported by the gear rim made of precision-cast aluminium for a custom-fit power transmission.

3 The compression spring is designed for a high number of load cycles and is free of fatigue while providing a safe power transmission to the bolts and clutch hub.

4 The grooved ring is made of heat-resistant material. Pairing of cylinders and pistons also ensures backlash-free mobility.

5 Outer disks with optimised coating for powerful friction, inner disks for reliable torque transmission.
