〈産業上の利用分野〉
本発明は、内燃機関のトルク変動緩和装置に関し、特に
、トルク変動の吸収作用を機関運転条件に応じて制御可
能な装置に関する。DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a torque fluctuation mitigation device for an internal combustion engine, and more particularly to a device capable of controlling the torque fluctuation absorption function according to engine operating conditions.
〈従来の技術〉
内燃機関の燃料消費率を向上するためには、機関を出来
るだけ低回転域で使用することが好ましいが、アイドリ
ング運転時等の低回転域では、機関回転数の低下に従っ
て回転数変動が顕著になり、トランスミッション部の騒
音や機関の振動等の問題が発生する。<Prior art> In order to improve the fuel consumption rate of an internal combustion engine, it is preferable to use the engine in a low speed range as much as possible, but in a low speed range such as during idling, the engine speed decreases as the engine speed decreases. The number fluctuation becomes noticeable, causing problems such as transmission noise and engine vibration.
従って、大きな慣性力を有したフライホイールを使用す
ることが考えられるが、機関寸法、形状、重量等の制約
を受けるため、実用的ではない。Therefore, it is conceivable to use a flywheel with a large inertial force, but this is not practical due to restrictions such as engine size, shape, weight, etc.
そこで、従来では、フライホイールの慣性力を増大する
ことなく、機関のトルク変動を吸収して、上記の問題点
を解消するようにしたトルク変動緩和装置が知られてい
る（実開昭５６−１５５１４３号公報、実開昭５８−１
７２０１８号公報及び実開昭５９−３２１３７号公報等
参照）。Therefore, conventionally, a torque fluctuation mitigation device has been known that solves the above problem by absorbing engine torque fluctuation without increasing the inertia force of the flywheel. Publication No. 155143, Utility Model Publication No. 1983-1
(See Japanese Utility Model Publication No. 72018 and Japanese Utility Model Application Publication No. 59-32137, etc.).
ここで、かかる従来のトルク変動緩和装置の一例を第３
図及び第４図に基づいて説明する。Here, an example of such a conventional torque fluctuation mitigation device will be described in the third section.
This will be explained based on the diagram and FIG.
