<p>A fluid-shear pulley (10) coupled to the engine crankshaft (12) operates on the principle of fluid-shear transmission of torque through liquid in the chamber (32) for the purpose of isolating torsional vibrations in the hub (14) of the pulley from the outermost, belt-driving portion (20) of the pulley. The fluid-shear pulley (10) thus serves to isolate torsional vibrations in the crankshaft (12) from the driving belt. This isolation of vibrations precludes attainment of resonant modes of vibration in the driving belt, thereby extending the life of the driving belt and making possible the use of a lighter and smaller driving belt. The belt (34), Fig. 2 (not shown). drives an alternator (36), a power steering pump (38) and a power brake pump (40). <IMAGE></p> |
