Embodiment Construction

[0046] Next, an embodiment of the auxiliary machine drive device 1 of the present invention will be described in detail with reference to the drawings.

[0047] Such as figure 1As shown, the auxiliary machine drive device 1 is attached to an internal combustion engine (hereinafter referred to as an engine E) for a vehicle. The engine E is a 4-cycle in-line multi-cylinder gasoline engine, which has: an engine body 2, which is composed of a cylinder block and a cylinder head, the cylinder block dividing the cylinder and a crankcase; a chain cover 3, which is fastened to the side of the engine body And cover timing chain; Oil pan 4, it is fastened on the lower end of engine main body 2; 6 is mounted on the vehicle in a slightly inclined state toward the rear of the vehicle. And, in figure 1 In FIG. 3 , the engine E is shown in a state of being mounted on a vehicle, with the vertical direction on the paper being the vertical direction. The following description is based on the...

Abstract

The invention provides an auxiliary engine driving device of an internal-combustion engine. The direction of a belt load applied by the auxiliary engine driving device to a crankshaft belt wheel is different from the axis of a cylinder, so that crashing is restrained. A V-shaped belt (15) is coiled on a compressor belt wheel (11), an AC generator belt wheel (12), a tensioning wheel (14) and a pump belt wheel(13) toward a tensioning side and by taking the crankshaft belt wheel (10) as the starting point. The compressor belt wheel (11) is configured at the side of the crankshaft belt wheel (10), and the pump belt wheel (13) is configured at the outer side of the V-shaped belt (15). The belt wheels are configured in the following manners that: the center of the pump belt wheel is configured in a triangle that is formed by connecting the centers of the crankshaft belt wheel (10), the compressor belt wheel (11) and the AC generator belt wheel (12), a first hypothetical point is located between a first hypothetical line (31) and a second hypothetical line (32), and a second hypothetical point is located between a third hypothetical line (33) and a fourth hypothetical line (34).

Description

technical field [0001] The invention relates to an auxiliary machine driving device for an internal combustion engine that drives three auxiliary machines via a crankshaft pulley. Background technique [0002] Generally, in an internal combustion engine having a plurality of cylinders, an auxiliary machine driving device using a belt is arranged at one end of the crankshaft along the direction in which the cylinders are arranged. The auxiliary machine driving device is constituted by winding a transmission belt around a crankshaft pulley fixed at one end of the crankshaft and auxiliary machine pulleys for driving each auxiliary machine. auxiliary machine. [0003] In recent years, in order to realize the miniaturization of the engine, the form of driving multiple auxiliary machines by one transmission belt is often used. In this case, a V-belt having a higher transmission capacity than a flat belt is often used as the transmission belt. In addition, in order to ensure fri...
