DRIVE DEVICE FOR VEHICLE AUXILIARY MACHINE

摘要

Not only is frictional load minimized when an auxiliary device is being driven, but energy loss is minimized by allowing for the selection of an efficient drive source. Provided are an engine (1), a motor/generator (2), and a compressor (3). In the present drive apparatus for a vehicle auxiliary device, an engine roller (4), a motor/generator roller (5), and a compressor roller (6) are linked to a rotary shaft of each of the engine (1), the motor/generator (2), and the compressor (3). A first idler roller (7), a second idler roller (8), and a third idler roller (9) are disposed at gap positions formed between the rollers (4), (5), (6). Also provided is a roller pair selection mechanism (10) for selecting a power-transmitting roller pair from among the rollers (4), (5), (6) by moving the idler rollers (7), (8), (9) in roller contact directions, thereby interposing the idler rollers (7), (8), (9) therebetween.
