<p>A belt and pulley system for the transmission of power from the crankshaft of an internal combustion engine to a plurality of power consuming devices, such as a generator/alternator, a power steering pump, a power brake pump, etc. The system employs a fluid shear pulley coupled to the engine crankshaft. The pulley employs the principle of fluid shear transmission of torque for the purpose of isolating torsional vibrations in the hub of the pulley from the outermost, belt-driving portion of the pulley. By virtue of this system, torsional vibrations in the crankshaft are effectively isolated 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 also making possible the use of lighter and smaller driving belt.</p> |
