Abstract
An air induction system (10) is disclosed including an improved drive assembly (12) constructed in accordance with the principles of a preferred embodiment of the present invention and configured for transmitting power to a blower (14). The illustrated drive assembly (12) broadly includes bracketry (26) for supporting the other components of the drive assembly (12), a primary drive pulley (22), a transfer drive subassembly (28) for transferring power from the pulley (22) downstream, a supercharger drive subassembly (30) for transferring power from the subassembly (28) to the supercharger (14), and an intermediate eccentric pulley shaft subassembly (32) adjustably inter-communicating the subassemblies (28) and (30). The intermediate eccentric pulley shaft subassembly (32) is adjustable so as to eliminate the need for an idler pulley on at least one of the subassemblies (28,30) and includes a shiftable bearing tube (76), and an intermediate eccentric pulley shaft (78) rotatably supported in the bearing tube (76) by a pair of bearings (80) and (82).
