本考案は、シリンダの外周にばねシートを設けると共に、ピストンロッド側に ばね受けを設け、これらばねシートとばね受けの間に懸架ばねを介装し、更にガ ス室と油室とを区画したリザーバを有し、シリンダの油室とリザーバの油室とを 連絡路を介して連絡してなる油圧緩衝器の懸架ばね荷重調整装置において、シリ ンダの外周に油圧ジャッキを設け、この油圧ジャッキにて前記ばねシートを担持 し、且つシリンダの外周にばね位置決め部材を位置調整自在に配設し、このばね 位置決め部材にて前記ばねシートを位置決め可能とし、前記シリンダの油室とリ ザーバの油室とを連絡する連絡路に切換弁を設け、切換弁は、通常時、上記連絡 路を導通し、且つ油圧ジャッキの油室から該連絡路への油の流れを許容しその逆 方向流れを阻止するものであり、ばね荷重調整時、シリンダの油室と油圧ジャッ キの油室とを導通し、且つリザーバの油室からシリンダの油室への油の流れを許 容しその逆方向流れを阻止するようにしたものである。 According to the present invention, a spring seat is provided on the outer circumference of the cylinder, a spring receiver is provided on the piston rod side, and a suspension spring is interposed between the spring seat and the spring receiver to further divide the gas chamber and the oil chamber. In a suspension spring load adjusting device for a hydraulic shock absorber that has a reservoir and connects the oil chamber of the cylinder and the oil chamber of the reservoir via a communication path, a hydraulic jack is provided on the outer circumference of the cylinder. The spring seat, and a spring positioning member is arranged on the outer periphery of the cylinder so that the position of the spring seat can be adjusted.

It was designed to prevent it.
【０００７】[0007]
本考案による懸架ばねの初期荷重調整は以下の如くなされる。 The initial load adjustment of the suspension spring according to the present invention is as follows.
【０００８】 (1) ばね荷重調整に際し、切換弁によりシリンダの油室と油圧ジャッキの油室 とを導通する。この状態で、油圧緩衝器に押込み力を付与してシリンダを原状態 から縮ませれば、シリンダが縮む際のロッド体積分の油が油圧ジャッキの油室に 侵入して油圧ジャッキを押し上げ、油圧ジャッキにて担持されているばねシート が懸架ばねを圧縮する。このとき、ばねシートはばね位置決め部材から離れ、ば ね位置決め部材は自由に位置調整可能となる。従って、上述のシリンダを縮ませ た状態を維持しておきながら、ばね位置決め部材を自由に位置調整し、このばね 位置決め部材を懸架ばねの初期設定荷重に相当する新たな設定位置に定める。(1) When adjusting the spring load, the switching valve connects the oil chamber of the cylinder to the oil chamber of the hydraulic jack. In this state, if pushing force is applied to the hydraulic shock absorber to contract the cylinder from the original state, the oil equivalent to the volume of the rod when the cylinder contracts enters the oil chamber of the hydraulic jack and pushes up the hydraulic jack. A spring seat carried by the jack compresses the suspension spring. At this time, the spring seat is separated from the spring positioning member, and the position of the spring positioning member can be freely adjusted. Therefore, the spring positioning member is freely adjusted in position while maintaining the above-mentioned compressed state of the cylinder, and the spring positioning member is set to a new setting position corresponding to the initial setting load of the suspension spring.
【０００９】 (2) ばね位置決め部材の位置設定完了後、切換弁を通常状態に切換える。これ により、油圧ジャッキ側の油が切換弁から連絡路側へ戻ることが可能となり、油 圧ジャッキは、懸架ばねにより押し戻されるばねシートが上述のばね位置決め部 材にて位置決めされる位置に達するまで収縮する。これにより、懸架ばねの初期 設定荷重が上述のばね位置決め部材の新たな設定位置に対応して決定される。(2) After the position setting of the spring positioning member is completed, the switching valve is switched to the normal state. This allows the oil on the hydraulic jack side to return from the switching valve to the communication path side, and the hydraulic jack contracts until the spring seat pushed back by the suspension spring reaches the position where it is positioned by the spring positioning member described above. To do. Thereby, the initial set load of the suspension spring is determined corresponding to the new set position of the spring positioning member.
【００１０】 また、このとき、シリンダが原状態に戻る伸び工程に際し、シリンダの伸びに 対応するロッド体積分の油はリザーバの油室から連絡路を介して補給される。Further, at this time, in the extension process in which the cylinder returns to the original state, the oil corresponding to the rod volume corresponding to the extension of the cylinder is replenished from the oil chamber of the reservoir through the communication path.
【００１１】 (3) 尚、上記(1) において、ばね位置決め部材の位置調整量が、シリンダを原 状態から 1回縮ませるだけでは得られない場合には、油圧緩衝器への押込み力付 与により 1回目のシリンダの縮み状態を維持しながらばね位置決め部材の 1回目 の位置調整を行なった後、シリンダを原状態に戻す。このとき、切換弁はリザー バの油室からシリンダの油室への油の流れを許容しているから、シリンダの戻り による伸びに対応するロッド体積分の油はリザーバの油室から補給され得る。そ して、油圧緩衝器への押込み力を再び付与し、 2回目のシリンダの縮み状態を維 持しながらばね位置決め部材の 2回目の位置調整を行なう如くを繰り返すことに なる。即ち、ばね荷重調整時、切換弁がリザーバの油室からシリンダの油室への 油の流れを許容することから、切換弁の切換え操作を伴うことなく、ばね位置決 め部材の 2回以上の位置調整を繰り返すことを可能とするのである。(3) In the above (1), when the position adjustment amount of the spring positioning member cannot be obtained by only contracting the cylinder from the original state once, the pushing force to the hydraulic shock absorber is applied. After adjusting the position of the spring positioning member for the first time while maintaining the compressed state of the cylinder for the first time, return the cylinder to the original state. At this time, since the switching valve allows the oil flow from the oil chamber of the reservoir to the oil chamber of the cylinder, oil corresponding to the expansion of the cylinder due to the cylinder return can be replenished from the oil chamber of the reservoir. .. Then, the pushing force to the hydraulic shock absorber is applied again, and the second position adjustment of the spring positioning member is performed while maintaining the compressed state of the cylinder for the second time. That is, when adjusting the spring load, the switching valve allows the flow of oil from the oil chamber of the reservoir to the oil chamber of the cylinder.Therefore, switching of the switching valve does not involve switching operation of the spring positioning member more than twice. The position adjustment can be repeated.
【００１２】 即ち、本考案は、油圧ジャッキの作動油として油圧緩衝器内の油を用いるもの である。従って、外部の圧力源を備えたり、外部配管の取回しを伴うことがなく 、簡素な構成により、懸架ばね荷重を調整できる。That is, the present invention uses the oil in the hydraulic shock absorber as the hydraulic oil for the hydraulic jack. Therefore, the suspension spring load can be adjusted with a simple configuration without providing an external pressure source or arranging external pipes.

【００２３】 次に、本実施例の作用について説明する。Next, the operation of this embodiment will be described.
【００２４】 本実施例による懸架ばね１９の初期荷重調整は以下の如くなされる。The initial load adjustment of the suspension spring 19 according to this embodiment is performed as follows.
【００２５】 (1) ばね荷重調整に際し、切換弁３７によりシリンダ１１の油室１６と油圧ジ ャッキ３１の油室３２とを導通する。この状態で、油圧緩衝器１０に押込み力を 付与してシリンダ１１を原状態から縮ませれば、シリンダ１１が縮む際のロッド 体積分の油が油圧ジャッキ３１の油室３２に侵入して油圧ジャッキ３１を押し上 げ、油圧ジャッキ３１にて担持されているばねシート１７が懸架ばね１９を圧縮 する。このとき、ばねシート１７はばね位置決め部材３５から離れ、ばね位置決 め部材３５は自由に位置調整可能となる。従って、上述のシリンダ１１を縮ませ た状態を維持しておきながら、ばね位置決め部材３５を自由に位置調整し、この ばね位置決め部材３５を懸架ばね１９の初期設定荷重に相当する新たな設定位置 に定める。(1) When adjusting the spring load, the switching valve 37 connects the oil chamber 16 of the cylinder 11 and the oil chamber 32 of the hydraulic jack 31 to each other. In this state, if a pushing force is applied to the hydraulic shock absorber 10 and the cylinder 11 is contracted from the original state, the oil equivalent to the volume of the rod when the cylinder 11 contracts enters the oil chamber 32 of the hydraulic jack 31 and the hydraulic pressure is increased. The jack 31 is pushed up, and the spring seat 17 carried by the hydraulic jack 31 compresses the suspension spring 19. At this time, the spring seat 17 is separated from the spring positioning member 35, and the spring positioning member 35 can be freely adjusted in position.

Establish.
【００２６】 (2) ばね位置決め部材３５の位置設定完了後、切換弁３７を通常状態に切換え る。これにより、油圧ジャッキ３１側の油が切換弁３７から連絡路２５側へ戻る ことが可能となり、油圧ジャッキ３１は、懸架ばね１９により押し戻されるばね シート１７が上述のばね位置決め部材３５にて位置決めされる位置に達するまで 収縮する。これにより、懸架ばね１９の初期設定荷重が上述のばね位置決め部材 ３５の新たな設定位置に対応して決定される。(2) After the position setting of the spring positioning member 35 is completed, the switching valve 37 is switched to the normal state. As a result, the oil on the side of the hydraulic jack 31 can return from the switching valve 37 to the side of the communication path 25. In the hydraulic jack 31, the spring seat 17 pushed back by the suspension spring 19 is positioned by the spring positioning member 35 described above. Contract until it reaches the desired position.

Then, the pushing force to the hydraulic shock absorber 10 is applied again, and the second position adjustment of the spring positioning member 35 is performed while maintaining the contracted state of the cylinder 11 for the second time. That is, when the spring load is adjusted, the switching valve 37 allows the flow of oil from the oil chamber 22 of the reservoir 24 to the oil chamber 16 of the cylinder 11, so that the spring positioning member can be operated without switching the switching valve 37.
