Torsionally Stiff Clutch Pneumastar

The PNEUMASTAR clutch is a torsionally stiff double-cone friction clutch. The clutching components consist of two inner and two outer friction cones of which the inner ones are pneumatically pressed against the outer tapered friction faces via a clutching cylinder. Rubber sleeve springs form the torsionally stiff portion of the clutch. As the clutching components are moved over the rubber sleeve springs during the actuation of the clutch, a wear-causing axial sliding movement between the various
