Description

本発明は、モータ、内燃機関等の回転駆動源の動きを安定化させるためのフライホイールに関し、特に、速度に応じて慣性および回転モーメントを変化させうるようにしたフライホイールに関するものである。  The present invention relates to a flywheel for stabilizing the movement of a rotational drive source such as a motor or an internal combustion engine, and more particularly to a flywheel that can change inertia and rotational moment according to speed.

フライホイールは、回転時の慣性を利用して回転速度の平均化を図るもので、一般に自動車の内燃機関に取付けられている。自動車の内燃機関にフライホイールを取付けた場合において、高速時においては、フライホイールは重い方が走行の安定性は向上するが、停止状態から加速する場合や減速から停止に至る場合は、フライホイールは軽い方が追従性が向上し、燃費は低減する。このような高速時の走行安定性と、加減速時の追従性という、相反する機能をフライホイールに持たせるためには速度に応じて慣性および回転モーメントを可変させる必要がある。  The flywheel is intended to average the rotational speed by utilizing inertia at the time of rotation, and is generally attached to an internal combustion engine of an automobile. When a flywheel is mounted on an internal combustion engine of an automobile, the flywheel is heavier at high speeds, and the stability of the run improves.However, if the flywheel accelerates from a stopped state or decelerates to stops, the flywheel The lighter the lighter the better the follow-up and the lower the fuel consumption. In order for the flywheel to have such contradictory functions of running stability at high speed and follow-up performance at acceleration / deceleration, it is necessary to vary the inertia and rotational moment according to the speed.

このように慣性および回転モーメントを可変させるフライホイールとして、回転軸の外周方向に移動可能に複数の重錘を配置し、これらの重錘を回転軸の方向に弾性部材で付勢し、回転数に応じて重錘の位置を可変するようにしたものがある（例えば、特許文献１参照）。  As a flywheel that varies the inertia and the rotational moment in this way, a plurality of weights are arranged so as to be movable in the outer peripheral direction of the rotating shaft, and these weights are urged by an elastic member in the direction of the rotating shaft, and the number of rotations There is one in which the position of the weight is changed in accordance with (see, for example, Patent Document 1).

That is, generally, there is a manufacturing error in the weight and the elastic body, and it is difficult to move the weight to an accurate position as intended in proportion to the rotation speed. For this reason, there is a problem that it is difficult to contribute to the stability of follow-up performance during acceleration / deceleration or high-speed running performance.

各図において、フライホイールＦは、モータ、内燃機関などの回転駆動源（図示せず）の回転軸１に固定された円盤状の本体２を有している。本体２の中央には、回転軸１に固定されたハブ３を有し、外周にはフランジ部４が形成されている。  In each figure, the flywheel F has a disk-shaped main body 2 fixed to a rotary shaft 1 of a rotary drive source (not shown) such as a motor or an internal combustion engine. A hub 3 fixed to the rotary shaft 1 is provided at the center of the main body 2, and a flange portion 4 is formed on the outer periphery.

本体２には放射状に４本のアリ溝５（図５参照）が形成され、それぞれのアリ溝５に扇型の重錘６が装着されている。図５に示すように、重錘６の裏面にアリ型６ａが形成され、このアリ型６ａがアリ溝５に摺動自在に嵌め込まれている。この重錘６とハブ３との間に引張ばね７が取付けられており、停止時又は減速時には、重錘６を図１に示すように最内端に引き寄せている。  The main body 2 is formed with four dovetail grooves 5 (see FIG. 5) radially, and fan-shaped weights 6 are attached to the respective dovetail grooves 5. As shown in FIG. 5, the dovetail 6 a is formed on the back surface of the weight 6, and the dovetail 6 a is slidably fitted in the dovetail groove 5. A tension spring 7 is attached between the weight 6 and the hub 3, and when stopping or decelerating, the weight 6 is pulled toward the innermost end as shown in FIG.

回転軸１の回転時に重錘６を最適の位置に設定するための重錘移動手段として、流体圧シリンダ８（油圧又は空気圧シリンダ）をフランジ部４に固定し、そのピストンロッド８ａを重錘６の裏面の取付部６ｂに固定している。この流体圧シリンダ８は制御バルブ（図示せず）に接続され、この制御バルブの制御によりピストンロッド８ａを任意の位置に停止させ、重錘６をその任意の位置に固定することができるようになっている。制御バルブは、回転軸１の回転速度を検出する手段からの電気信号により制御されるようになっている。回転速度の検出手段は、例えば、自動車であれば、車速メータ、制動装置、変速機あるいはアクセルの開度変化量等の情報などを電気信号として取り出すものである。この電気信号により制御バルブを制御し、ピストンロッド８ａの位置を任意の位置で停止させることにより、重錘の位置を速度に応じて最適位置に設定するようになっている。  A fluid pressure cylinder 8 (hydraulic or pneumatic cylinder) is fixed to the flange portion 4 as a weight moving means for setting the weight 6 to an optimum position when the rotary shaft 1 rotates, and the piston rod 8a is fixed to the weight 6. It is being fixed to the attachment part 6b of the back surface. The fluid pressure cylinder 8 is connected to a control valve (not shown), and the piston rod 8a is stopped at an arbitrary position by the control valve, so that the weight 6 can be fixed at the arbitrary position. It has become. The control valve is controlled by an electric signal from a means for detecting the rotational speed of the rotary shaft 1. For example, in the case of an automobile, the rotational speed detection means extracts information such as a vehicle speed meter, a braking device, a transmission, or an opening change amount of an accelerator as an electrical signal. By controlling the control valve by this electric signal and stopping the position of the piston rod 8a at an arbitrary position, the position of the weight is set to the optimum position according to the speed.

停止状態から起動して最初に加速する際には、図１、図３に示すように、重錘６は慣性が最も小さい最内周位置で固定されていることが好ましい。そのため、重錘６を最内周の位置で固定する低速固定手段１０を設けている。低速固定手段１０は、本体２に固定された流体圧シリンダ１１のピストンロッド１１ａを重錘６の外周に当接することにより、重錘６をそれ以上外周方向に動かないように固定するものである。  When starting from a stop state and accelerating for the first time, as shown in FIGS. 1 and 3, the weight 6 is preferably fixed at the innermost circumferential position where the inertia is the smallest. Therefore, low speed fixing means 10 for fixing the weight 6 at the innermost peripheral position is provided. The low speed fixing means 10 fixes the weight 6 so as not to move further in the outer peripheral direction by contacting the piston rod 11a of the fluid pressure cylinder 11 fixed to the main body 2 to the outer periphery of the weight 6. .

また、図２、図４に示すように、高速安定時に重錘６を一定位置で固定する高速固定手段１３を設けている。高速固定手段１３は、本体２に固定された流体圧シリンダ１４のピストンロッド１４ａを重錘６の内周に当接することにより、重錘６をそれ以上内周方向に動かないように固定するものである。  Further, as shown in FIGS. 2 and 4, high-speed fixing means 13 for fixing the weight 6 at a fixed position is provided when the high-speed is stable. The high-speed fixing means 13 fixes the weight 6 so as not to move further in the inner circumferential direction by contacting the piston rod 14a of the fluid pressure cylinder 14 fixed to the main body 2 with the inner circumference of the weight 6. It is.

一般に、回転体の慣性は質量と重心位置とにより計算される。
例えば、厚さ２０ｍｍ、直径５００ｍｍの鉄のフライホイールでは、以下のように計算される。
慣性＝０９６３（Ｋｇ・ｍ２）
回転モーメント＝３８５（Ｋｇｆ・ｍ２）In general, the inertia of the rotating body is calculated by the mass and the position of the center of gravity.
For example, in an iron flywheel having a thickness of 20 mm and a diameter of 500 mm, the calculation is performed as follows.
Inertia = 0963 (Kg · m 2 )
Rotational moment = 385 (Kgf · m 2 )

本発明の可変モーメント方式のフライホイールＦは、重錘６を移動させることにより、慣性及び回転モーメントを変化させるものである。フライホイールＦを自動車のエンジンに適用した場合について述べると、自動車を停止状態では図１のように、重錘６は引張ばね７により最も内側に移動した状態で停止している。この状態からアクセルで加速していくことにより、回転軸１が回転して重錘６に遠心力が働き、回転速度に応じて引張ばね７に抗して外周方向に移動する。  The variable moment flywheel F of the present invention changes the inertia and the rotational moment by moving the weight 6. When the flywheel F is applied to an automobile engine, the weight 6 is stopped in a state where it is moved inward by a tension spring 7 as shown in FIG. By accelerating with the accelerator from this state, the rotating shaft 1 rotates and centrifugal force acts on the weight 6 and moves in the outer peripheral direction against the tension spring 7 according to the rotational speed.

本発明では、重錘６の位置を回転速度に正確に対応させるため、重錘移動手段として流体圧シリンダ８を用いている。上述のように、流体圧シリンダ８は、車速メータ、制動装置、変速機、あるいはアクセルの開度変化量の情報などを電気信号として取り出し、この電気信号により制御バルブ（図示せず）を制御し、ピストンロッド７ｂの位置を任意の位置で停止させるものである。  In the present invention, in order to accurately correspond the position of the weight 6 to the rotational speed, the fluid pressure cylinder 8 is used as the weight moving means. As described above, the fluid pressure cylinder 8 extracts information such as a vehicle speed meter, a braking device, a transmission, or an accelerator opening change amount as an electrical signal, and controls a control valve (not shown) by this electrical signal. The position of the piston rod 7b is stopped at an arbitrary position.

このような重錘移動手段を用いないで、引張ばね７のみ場合、重錘６や引張ばね７の製造誤差により、速度と重錘６の位置が正確に対応できず、そのため充分な加速性能の向上や燃費の向上をはかることができにくいという問題があった。  Without using such weight moving means, when only the tension spring 7 is used, the speed and the position of the weight 6 cannot be accurately matched due to manufacturing errors of the weight 6 or the tension spring 7, so that the acceleration performance is sufficient. There was a problem that it was difficult to improve the fuel consumption and fuel consumption.

本発明では、車速メータ、制動装置、変速機、あるいはアクセルの開度変化量の情報などを電気信号として取り出し、この電気信号により制御バルブを制御し、ピストンロッ８ａを介して重錘６を最適の位置に停止させるので、自動車に適用した場合、加減速時には回転モーメントを小さくしてアクセル追従性を良好にするとともに、高速走行時は回転モーメントを大きくしてフライホイールＦ自体が持つトルクを上げる。  In the present invention, information such as a vehicle speed meter, a braking device, a transmission, or an accelerator opening change amount is taken out as an electrical signal, and the control valve is controlled by this electrical signal, and the weight 6 is optimized via the piston lock 8a. Since it is stopped at the position, when applied to an automobile, the rotational moment is reduced during acceleration / deceleration to improve accelerator followability, and during high speed traveling, the rotational moment is increased to increase the torque of the flywheel F itself.

慣性および回転モーメントは、フライホイールＦの重心が回転軸１に近いほど小さくなり、重心が外周方向に移動するほど大きくなるという特性がある。このような物理的特性を用いて、加減速時及び減速時に慣性および回転モーメントを小さくすることにより、加減速性能（速度追従性）が向上するとともに、燃費性能が向上する。また、高速走行時には慣性および回転モーメントを大きくすることにより、上り坂や下り坂などにおけるエンジンの負荷変動を小さくし、燃費の向上を図ることができる。  Inertia and rotational moment have characteristics that the smaller the center of gravity of the flywheel F is, the smaller it is, and the larger the center of gravity moves in the outer circumferential direction. By reducing the inertia and rotational moment during acceleration / deceleration and deceleration using such physical characteristics, acceleration / deceleration performance (speed follow-up performance) is improved and fuel consumption performance is improved. Further, by increasing the inertia and the rotational moment during high-speed traveling, it is possible to reduce engine load fluctuation on an uphill or downhill and improve fuel efficiency.

さらに本発明では、停止状態から起動して最初に加速する際に重錘６を一定位置で固定する低速固定手段１０を設けるとともに、高速安定時にも重錘６を一定位置で固定する高速固定手段１１を設けている。低速固定手段１０は、流体圧シリンダ１１のピストンロッド１１ａを重錘６の外周に当接することにより重錘を外周方向に移動しないように固定する。また、高速固定手段１３は、流体圧シリンダ１４のピストンロッド１４ａを重錘６の内周に当接することにより、重錘６を内周方向に移動しないように固定する。  Further, in the present invention, there is provided low speed fixing means 10 for fixing the weight 6 at a fixed position when starting acceleration from the stop state and first accelerating, and high speed fixing means for fixing the weight 6 at a fixed position even when the high speed is stable. 11 is provided. The low speed fixing means 10 fixes the weight so that it does not move in the outer peripheral direction by bringing the piston rod 11a of the fluid pressure cylinder 11 into contact with the outer periphery of the weight 6. The high-speed fixing means 13 fixes the weight 6 so as not to move in the inner circumferential direction by contacting the piston rod 14a of the fluid pressure cylinder 14 with the inner circumference of the weight 6.

図１に示すように、重錘６の慣性および回転モーメントが最も小さい最内側位置にある時点でエンジンを起動する場合、重錘６が停止したままのほうが加速しやすいため、加速が安定するまで低速固定手段１０により重錘６を固定させておく。  As shown in FIG. 1, when the engine is started at the time when the weight 6 is at the innermost position where the inertia and the rotational moment are the smallest, it is easier to accelerate while the weight 6 is stopped. The weight 6 is fixed by the low speed fixing means 10.

加速度が安定してきた時点でピストンロッド１１ａを引き込み、固定を解除すると、速度が上昇するにしたがって遠心力で重錘６は引張ばね７に抗して外周方向に移動していく。この際、遠心力のみで重錘６を外周方向に移動させるのではなく、自動車の速度情報、すなわち、車速メータ、制動装置、変速機等の情報あるいはアクセルの開度変化量の情報など、所望の情報を電気信号として取り出し、この電気信号により制御バルブを制御し、流体圧シリンダ８のピストンロッド８ａにより重錘６を自動車の速度に応じた最適の位置に設定する。  When the piston rod 11a is pulled in and the fixation is released when the acceleration is stabilized, the weight 6 moves in the outer peripheral direction against the tension spring 7 by centrifugal force as the speed increases. At this time, instead of moving the weight 6 in the outer circumferential direction only by the centrifugal force, the vehicle speed information, that is, information on the vehicle speed meter, the braking device, the transmission, etc., or information on the amount of change in the accelerator opening is desired. This information is taken out as an electrical signal, the control valve is controlled by this electrical signal, and the weight 6 is set to the optimum position according to the speed of the automobile by the piston rod 8a of the fluid pressure cylinder 8.

自動車が高速安定で走行している場合は、重錘６が停止したままのほうが高速安定走行しやすいため、高速状態を継続する場合は、高速固定手段１３により重錘６を固定させておく。すなわち、高速固定手段１３である流体圧シリンダ８のピストンロッド７ｂを突出させて重錘６の内周に当接させ、重錘６を固定する。高速走行を中止し、走行速度が変動する走行に移行する場合は、高速固定手段１３のピストンロッド１４ａを引っ込め、重錘６を移動させる通常の走行状態とする。
低速固定手段１０及び高速固定手段１３は、上記した自動車の速度情報に基いて制御バルブを介して流体圧シリンダ１１，１４を制御し、ピストンロッド１１ａ、１４ａを突出又は引っ込めるようにしている。When the automobile is traveling at high speed and stable, it is easier to travel stably at high speed while the weight 6 is stopped. Therefore, when the high speed state is to be continued, the weight 6 is fixed by the high speed fixing means 13. That is, the piston rod 7b of the fluid pressure cylinder 8 which is the high-speed fixing means 13 is protruded and brought into contact with the inner periphery of the weight 6 to fix the weight 6. When the high speed travel is stopped and the travel is changed to a travel where the travel speed fluctuates, the piston rod 14a of the high speed fixing means 13 is retracted and a normal travel state in which the weight 6 is moved is set.
The low-speed fixing means 10 and the high-speed fixing means 13 control the fluid pressure cylinders 11 and 14 via the control valve based on the vehicle speed information described above, and project or retract the piston rods 11a and 14a.

上記実施形態において、重錘６は扇型に限定されず、どのような形状であってもよい。また、重錘６の個数も４個に限定されず、任意の個数であってよく、それぞれの重錘に対して重錘移動手段を設けるものとする。また、重錘６を付勢する手段は引張ばね７に限定されず、所望の弾性部材を使用することができる。  In the said embodiment, the weight 6 is not limited to a fan shape, What kind of shape may be sufficient. Further, the number of weights 6 is not limited to four, and may be any number, and weight moving means is provided for each weight. Further, the means for biasing the weight 6 is not limited to the tension spring 7, and a desired elastic member can be used.

また、重錘移動手段、低速固定手段１０、高速固定手段１３として流体圧シリンダを用いているが、これに限定されず、例えば、ソレノイドによりプランジャを移動させたり、あるはモータ駆動のリンク機構などを用いることも可能である。  Further, although the fluid pressure cylinder is used as the weight moving means, the low speed fixing means 10 and the high speed fixing means 13, it is not limited to this. For example, the plunger is moved by a solenoid or a motor-driven link mechanism or the like. It is also possible to use.

さらに、回転駆動源は自動車のエンジンの例を説明したが、自動車に限定されず、あらゆる内燃機関、モータに適用でき、また、自動車のほか、自転車その他あらゆる乗り物にも適用可能である。  Furthermore, although the example of the engine of the automobile has been described as the rotational drive source, it is not limited to the automobile, but can be applied to any internal combustion engine and motor, and can be applied to any other vehicle besides a car.
