Abstract

An auxiliary machine-driving device has a first idler roller having an outer peripheral surface biased into contact with the outer peripheral surfaces of a motor/generator roller and an engine roller, a second idler roller having an outer peripheral surface biased into contact with the outer peripheral surfaces of the engine roller and a rotating roller, and a third idler roller having an outer peripheral surface biased into contact with the outer peripheral surfaces of the rotating roller and the motor/generator roller. When the engine starts, the engine is started by transmitting the driving force of the motor/generator to the engine via the motor/generator roller, the first idler roller and the engine roller. After the engine starts, power is generated from the driving force of the engine being transmitted to the motor/generator via the engine roller, the second idler roller, the rotating roller, the third idler roller and the motor/generator roller.

First claim

The invention claimed is:

1. An auxiliary machine-driving device for a vehicle, the auxiliary machine-driving device comprising:
an engine roller that integrally rotates with a crank shaft of an engine;
a motor/generator roller that integrally rotates with a rotary shaft of a motor/generator;
a rotating roller that integrally rotates with a rotary shaft of an auxiliary machine that is driven by the engine or the motor/generator;
a first idler roller that is biased in a direction in which an outer peripheral surface of the first idler roller comes into contact with outer peripheral surfaces of the motor/generator roller and the engine roller;
a second idler roller that is biased in a direction in which an outer peripheral surface of the second idler roller comes into contact with outer peripheral surfaces of the engine roller and the rotating roller; and
a third idler roller that is biased in a direction in which an outer peripheral surface of the third idler roller comes into contact with the outer peripheral surfaces the rotating roller and the motor/generator roller;
wherein
when the engine starts, the engine is started by transmitting the driving force of the motor/generator to the engine via the motor/generator roller, the first idler roller and the engine roller, and after the engine starts, power is generated by the motor/generator by transmitting the driving force of the engine to the motor/generator via the engine roller, the second idler roller, the rotating roller, the third idler roller and the motor/generator roller.

2. The auxiliary machine-driving device as recited in claim 1 , wherein
the engine roller, the rotating roller and the motor/generator roller are arranged in that order in a direction of rotation of the engine roller when viewed from a direction of an axis of rotation of the engine roller.

3. The auxiliary machine-driving device as recited in claim 1 , wherein
the rotating roller integrally rotates with a drive shaft of a water pump that provides cooling water to the engine.

4. The auxiliary machine-driving device as recited in claim 2 , wherein
the rotating roller integrally rotates with a drive shaft of a water pump that provides cooling water to the engine.
