Abstract

A movable member (3) having a plurality of coaxial cylindrical walls and adapted to be rotated with a movable shaft (2) which is turned by an external force, and a fixed member (7) having a plurality of coaxial cylindrical walls, which are located uniformly spaced from and alternately with the walls of the movable member (3) when the members (3, 7) are fitted in each other, are set in a meshed state in a casing (1) in which a viscous fluid is held. One or both of the movable member (3) and fixed member (7) are formed so that they can be turned along the threads thereon to enable the area of the opposed portions of the movable member (3) and fixed member (7) to increase or decrease in accordance with the turning of a turning adjuster (5). When the turning adjuster (5) is turned, the meshing depth of the movable member (3) and fixed member (7) varies. Accordingly, the viscous shearing resistance produced by the viscous fluid existing between the fixed member (7) not in motion and the movable member (3) which receives this turning force varies in proportion to the above-mentioned area of the opposed portions thereof, whereby the braking force of the damper can be freely regulated.

明 細 書 - 粘性流体 を用いた回転同軸多筒板式ダンバ一  Description-Rotating coaxial multi-cylinder plate type damper using viscous fluid
技 術 分 野  Technical field
本発明は ボ リ ィ ソ ブチ レ ンなどの高分子粘性流体 その 他の粘性流体を用い、 その粘性剪断抵抗を利用する こ と に よ り 抵抗力を得る よ う に し、 当該抵抗力に よ っ て外力 に対す る緩衝作用すなわち制動力を発揮さ せ る よ う に し た各種の用途 に供 し得る回転同軸多筒板式ダ ンパー の改 良に関する 。  The present invention uses a polymer viscous fluid such as polysobutylene or other viscous fluids, and obtains a resistance by utilizing its viscous shear resistance. Accordingly, the present invention relates to an improvement of a rotary coaxial multi-cylinder plate type damper capable of exerting a damping action against external force, that is, a braking force, which can be used in various applications.
技 術 の 背 景  Background of technology
従来の ダ ンパーには、 既知の如 く 油を用 い、 これが狭 い通隙 を通 る と き の乱流抵抗を利用する よ う に し た も の が多用 されて来た。  Conventional dampers have been heavily used, which uses oil as is known, and uses the turbulence resistance when passing through a narrow passage.
し か し、 当該緩衝装置に よ る と き は、 所定の抵抗力に よ る 制動を得るのに、 上記の通隙に対 し高い精度が要求 される こ と と な り 、 また衝擊的な外力を受けた際 に は、 油が圧縮不能であ るため、 各部材に外力そ の ま ま の衝擊 が加わ る こ と と な り 、 この結果高い強度が必要 と な る こ と か ら大形化 して しま う難点がぁ リ 、 さ ら に 当該通隙が 汚物に よ り 狭塞されて し ま ラ と いった支障が生ず る 虞れ も あ る 。  However, in the case of using the shock absorber, high precision is required for the above-mentioned gap to obtain braking by a predetermined resistance, and also, an impact is required. When an external force is applied, the oil is incompressible, so that each member is subjected to the same impact as the external force, and as a result, high strength is required. There is a risk that the shape will be difficult, and there is also a risk that the pores will be blocked by dirt, which may cause troubles.
そ こ で、 上記従来方式のダンパーがもつ欠陥を解消す るた め 、 相対運動を行 う二物体の相近接す る 二面間 に、 高粘性 を も っ た粘性流体を配在させておき 、 上記相対運 動に際 し て生ずる 、 当該粘性流体の粘性剪断抵抗を利用 し、 こ の粘性流体に内部昇圧を発生させる こ と な し に、 外力に対する 抵抗力 を得るよ う に した方式の緩衝装置 が、 既に開発されるに至っている。 Therefore, in order to eliminate the defects of the conventional damper described above, a viscous fluid with high viscosity is arranged between two adjacent surfaces of two objects that perform relative motion. Utilizes the viscous shear resistance of the viscous fluid generated during the relative movement. However, a shock absorber of a type that obtains a resistance against an external force without generating an internal pressure increase in the viscous fluid has already been developed.
上記方式による初期のダンパーの一つと して、 既に実 公昭 5 6— 5 6 1 8号の Γ多筒式粘性ダンバ一 j が知られてい る。  As one of the early dampers based on the above method, the multi-cylinder viscous damper j of JP-B-56-51618 has already been known.
これは、 ケ一シ ング内に、 外力にょ リ 回転する可動軸 と共に回転する同軸多筒 置の所要数可動板と、 これら の可動板と交互に均等離間状態と した同軸多筒 K置であ る所要数の固定板とが晴合状態にて S設され 、 当該ケ— シ ング内の粘性流体が、 これら可動板、 固定板の板面間 に配在されているダンバーであ リ 、 それな り の利点を有 するが、 可動板と固定扳とが何れも位置不変の状態に設 け られてお り 、 当該ダンパ一と しての制動力を増減変更 して各種用法に適合させる といったこ とができないもの であ る。  This is a required number of movable plates of coaxial multi-cylinders that rotate together with a movable shaft that rotates in response to an external force in a casing, and a coaxial multi-cylinder K unit that is alternately and equally spaced from these movable plates. A required number of fixed plates are set in a balanced state, and the viscous fluid in the casing is a damper disposed between the surfaces of the movable plate and the fixed plate. Although there are some advantages, both the movable plate and the fixed 扳 are set in the position-invariant state, and the braking force as the damper is increased or decreased to adapt to various usages. It cannot do this.
太発明は上記従来例に鑑み、 同種ダンバ一でめ る同 ¾ 多筒板式の も のにあ っ て、 可動扳、 固定板の —方または 双方を 、 外部か ら の箇易な操作によ っ て変動自在と な し、 このこ と によって両扳の対向面積を増減変更させた り 、 また必要に応 じ 当該粘性流体を加圧して、 その密 度、 従っ て粘性をも加減でぎる よ うにし、 当該ダーパ一 の制動力を簡易に微調整可能とするのが、 その 目 的であ る。  In view of the prior art described above, according to the invention of the prior art, the same multi-cylinder plate type is mounted on the same type of damper, and one or both of the movable plate and the fixed plate are easily operated from the outside. This makes it possible to increase or decrease the facing area between the two surfaces, or to pressurize the viscous fluid as necessary to adjust its density and hence its viscosity. The purpose is to make it possible to easily and finely adjust the braking force of the damper.

A required number of fixed plates in a coaxial multi-cylinder arrangement in an evenly spaced state are arranged in a combined state, and the viscous fluid in the casing is distributed between the surfaces of the movable plate and the fixed plate. In the damper, one or both of the movable plate and the fixed plate can be freely screwed in the axial direction to increase or decrease the facing area of the two plates by rotating the rotation adjuster. It is an object of the present invention to provide a rotary coaxial multi-cylinder plate type vehicle using a viscous fluid having such a configuration.

Is increased or decreased, so that when an external force applies a rotational force to the movable plate, viscous shearing occurs in the viscous fluid existing between the stationary fixed plate and the movable plate subjected to the rotational force. Since the resistance changes in proportion to the size of the facing area, the damping force of the damper can be adjusted to a desired value.
