Abstract: 1,226,572. Friction clutch. FICHTEL & SACHS A.G. 18 March, 1968 [18 March, 1967], No. 12898/68. Heading F2C. A temperature-controlled clutch between a driving pulley 14 and an engine cooling fan 10 is engaged rapidly by means independant of temperature after initial clutch engagement has been produced by a temperature-sensitive element 24. The wax-filled temperature sensitive element 24 acts through a plunger 30 and spring 42 to move left, against the bias of a return spring 40, a hub 38 and clutch element 39 of a secondary clutch 31. The hub 38 has cam projections 45, (46) which pass through slots 47 in a sleeve 22 fast with the driving pulley 14 and co-operate with cam surfaces (58) on the clutch element 39. At a predetermined temperature initial engagement between the clutch element 39 and a friction surface 33 on the fan 10 causes a drag on the clutch element 39, whereupon interaction between the cam surfaces 45, (58) produces a torque responsive clutch engaging force which rapidly engages both the secondary clutch 31 and a primary clutch 34. As the temperature falls the hub 38 moves right until the cam projections 45, (46) pass over the cam surfaces (58), whereupon the torque responsive force is relieved and the clutch disengages rapidly. Spring strips 50, (51) prevent the clutch element 39 overrunning the hub 38. The friction surfaces 33, 34 of the primary and secondary clutches may have different coefficients of friction. Figs. 5 and 6 (not shown) are alternate embodiments which do not form part of the invention. In Fig. 5, a nut (86) threaded on a shaft (71) fast with the driving pulley (14) is adjustably connected to a cup (107) fast with the shaft (71) by a bimetal spiral temperature responsive element (87). The bi-metal spiral (87) screws the nut (86) along the shaft (71) as the temperature rises until initial engagement of a secondary clutch (82) occurs. Thereafter frictional drag screws the nut (86) further along the shaft (71) to rapidly engage both primary and secondary clutches (81, 82). In Fig. 6 a wax-filled temperature sensitive element (24<SP>1</SP>) acts through a plunger (30<SP>1</SP>) to compress a spring (104) and to move a driven clutch element (97) fast with the fan towards a driving clutch plate (90) fast with the pulley (14). At a predetermined temperature the force of the spring (104) together with the attraction of a permanent magnet (91) on the driving clutch plate (90) overcomes the action of a return spring (103) to engage the clutch with a snap action. When the temperature falls the compression of the spring (104) is reduced until the force of the return spring (103) overcomes the action of permanent magnet (91) and spring (104) to disengage the clutch.
