れる状態が生じる。2. Description of the Related Art In a vehicle such as an automobile, the running speed of the internal combustion engine varies greatly depending on the running condition, from a low idling speed of less than 1000 rpm to a maximum speed which is usually several times higher. It is better to drive at a suitable constant speed rather than directly related to engine auxiliary equipment such as air conditioner compressor, alternator, cooling water pump, oil pump for power steering, etc. If it is driven directly by the engine through something like a constant belt transmission, the rotation speed will be insufficient at idling, but
When the engine rotates at a high speed, the number of revolutions becomes excessive, which causes a state in which the engine is driven within a range of revolutions that is unsuitable.

A well-known continuously variable transmission 22 having a structure in which variable-diameter V pulleys 16 and 18 and a V belt 20 are combined is inserted between the shaft 14 and the continuously variable transmission 2 according to the engine speed.
By automatically adjusting the gear ratio of No. 2 so that the rotational speed of the shaft 14 does not change so much even if the engine rotational speed fluctuates, the various auxiliary machines as described above are driven from the shaft 14. Attempts have been made to configure such. (For example, see Japanese Utility Model Laid-Open No. 63-110752.)

や信頼性が低下する等の問題がある。As a continuously variable transmission that can be used as such an auxiliary machine drive device, a combination of a variable-diameter V pulley and a V belt, which is also found in the above-mentioned prior art, and friction are used. A combination of cars is considered, but generally friction type continuously variable transmission has more transmission loss due to friction and slip compared to a constant speed transmission using gears and V-belts. Since the transmission efficiency is usually low, in the case where the auxiliary machine is driven through the continuously variable transmission over the entire range of the engine speed as in the prior art, the engine speed is supplemented. Even when the engine speed is within the range suitable for driving the machine, the power is transmitted through the continuously variable transmission, and the transmission loss of the continuously variable transmission constantly occurs, resulting in a decrease in the overall transmission efficiency and the engine. Fuel economy, and There are problems such as the durability and reliability is lowered by premature wear of machine parts.

A pulley attached to the output shaft of the continuously variable transmission via a one-way clutch,
A variable speed auxiliary device for an internal combustion engine, comprising: a pulley attached to one or more auxiliary devices to drive each auxiliary device; and a series of belts wound around the pulleys. A machine driving device is provided.

よって前記入力軸上で空転している。When the internal combustion engine is in an operating state and is in a relatively low rotation speed range, the rotation of the crankshaft of the engine is transmitted through the continuously variable transmission and further to the output shaft of the continuously variable transmission. A pulley mounted via a one-way clutch is transmitted by a series of belts to the pulleys that drive each accessory. At this time, the rotation speed of the pulley attached to the input shaft of the continuously variable transmission via the one-way clutch becomes higher than the rotation speed of the input shaft. Idle above.

ので、無段変速機による動力の伝達ロスが減少する。When the rotational speed of the internal combustion engine becomes higher, the gear ratio of the continuously variable transmission is adjusted toward the direction of decreasing the speed ratio, and the rotational speed of the output shaft of the continuously variable transmission is unidirectional to the rotational speed of the output shaft of the continuously variable transmission. Since the rotation speed of the pulley attached via the clutch is increased by being driven by the pulley and the series of belts attached via the one-way clutch to the input shaft of the continuously variable transmission, The pulley attached to the output shaft of the continuously variable transmission via the one-way clutch shall idle on the output shaft of the continuously variable transmission by the one-way clutch, and the rotation of the crankshaft shall go through the continuously variable transmission. Instead, the power is transmitted from the input shaft directly to the series of belts, and thereby to the pulleys that drive the respective auxiliary machines, so that the power transmission loss by the continuously variable transmission is reduced.

うに構成しているのが第２の特徴である。One of the features of the embodiment of the present invention shown in FIGS. 1 to 3 is that even in the input shaft of the continuously variable transmission 22, it becomes clear as compared with FIGS. 4 and 5 showing the prior art. In addition to the variable-diameter V pulley 16 and the constant-diameter pulley 38 on a certain crankshaft 12.
(The pulley 38 in FIG. 1 is drawn with a slightly smaller diameter than in FIGS. 2 and 3 in order to avoid the belts and pulleys from overlapping each other.) And a series of belts 32 is also provided in this pulley 38. It's wrapped around. By doing so, the rotation speed of the shaft 14 does not change even when the continuously variable transmission 22 performs a gear shifting operation. Therefore, between the input shaft 12 and the pulley 38 supported by it, and between the output shaft 14 and its support. When the one-way clutches 40 and 42 are inserted between the pulleys 30 and 34 and the rotation speeds of the shafts 12 and 14 become higher than the rotation speeds of the pulleys 38 and 30, respectively. However, the second feature is that the transmission is performed from the shaft to the pulley and the reverse case or the reverse drive from the pulley to the shaft is not performed.

て空転状態になる。With this configuration, in the embodiment shown in FIGS. 1 to 3, when the internal combustion engine 10 is operated in a relatively low speed range such as idling, the speed ratio of the continuously variable transmission 22 is It is decided to a relatively large value. Thereby, the rotation speed of the shaft 14 which is the output shaft of the continuously variable transmission 22 becomes
Since the rotation speed of the pulley 30 becomes higher than that of the pulley 30 when driven at a constant speed ratio via the specially provided pulley 38 and the belt 32, the motive power is as shown by the arrow in FIG.
4 to the pulley 30 and the belt 32 via the one-way clutch 42. In this state, the rotation speed of the crankshaft 12 is lower than that of the pulley 38, so that the pulley 3
The one-way clutch 40 causes the crankshaft 12 to idle.

リ３０を駆動することはない。When the rotation speed of the internal combustion engine 10 increases,
Accordingly, the gear ratio of the continuously variable transmission 22 is also changed to adjust the rotation speed of the pulley 30 so as to gradually increase, or to maintain a substantially constant value.
In a high-speed operating state of the engine that exceeds the adjustable range of the continuously variable transmission 22, the rotation speed of the crankshaft 12 becomes higher than that of the pulley 38, and the one-way clutch 40 is engaged.
As shown by the arrow in FIG. 3, the power is switched from the pulley 38 to the belt 32. In this state, the rotation speed of the pulley 30 is higher than that of the shaft 14, so the one-way clutch 42 idles and the pulley 30 is transferred from the continuously variable transmission 22 via the shaft 14 and the one-way clutch 42. It never drives.

Since the transmission is performed by the belt transmission device having the constant rotation ratio including the crankshaft 12, the pulley 38, and the belt 32 without passing through the continuously variable transmission 22, the power transmission loss is reduced, and the transmission efficiency is increased. Since the load on the step transmission 22 is reduced, the variable diameter pulleys 16 and 18 of the belt 20 are
Wear due to friction with respect to the belt 20 is reduced, and the durability of the continuously variable transmission 22 including the belt 20 is also improved.

The rotational speed of the internal combustion engine 10 is rotatably driven via 26 and 28, and in some cases, such as an auxiliary machine 36 is directly driven from the shaft 14, so that the rotational speed of the internal combustion engine 10 is not substantially different from the rotational speed. There is a problem that it is driven at a constant or a relatively narrow range of rotation speed, and it is driven at an unnecessarily high rotation speed as in the past, which deteriorates durability, or it is driven at a low rotation speed of insufficient rotation speed.
