1,003,283. Friction clutches. B. HIRANO. Nov. 3, 1961 [Dec. 3, 1960], No. 39393/61. Heading F2L. The pressure engaging a centrifugally or manually-controlled friction clutch in a motor cycle &c. is reduced as the transmitted torque increases, by shear forces acting on one or more non-metallic coupling members in the drive path. As shown, a driving shaft 1 is fast with a drum in which are splined discs 4 interleaved with driven clutch discs carried in a drum 6 rotatable about the driving shaft. Axially-directed non-metallic coupling members in the form of rubber rods 11 transmit torque to a driven gear 10. The clutch is engaged by pressure transmitted through a rod 12. Increasing torque causes the rubber rods 11 to turn relatively to the clutch axis, due to the shear forces developed, and thus reduces the clutch-engaging pressure. |
