Description

悬架装置
技术领域
本发明涉及悬架装置。
背景技术
专利文献1公开了将液压减震器收容到电磁减震器的内部。在此，液压减震器的活塞设有流体通路和穿插于该流体通路中的销。并且，在通常行程中，由于销的销缩径部面向流体通路而形成较大的空隙，因此液压减震器的衰减力降低。另外，在端部侧行程区域中，由于销的大径部面向流体通路，因此液压减震器的衰减力增大。

具体实施方式
以下，说明本发明的实施方式的2个例子。
＜实施方式1＞
图1是作为本发明的一个实施方式的悬架装置的剖视图。以下存在将悬架装置1的图1中的右侧的前端部侧称为前端侧的情况。另外，存在将悬架装置1的图1中的左侧称为后方侧的情况。
悬架装置1具备液压式减震器3。液压式减震器3由杆11、活塞12、阀13、14等构成。液压式减震器3作为常规的悬架发挥功能。即，在作为悬架装置1的外侧框体的外筒4的内侧收纳有内筒5。在内筒5的内部收纳有与内筒5同轴芯的杆11。杆11能够在内筒5内沿着内筒5的长尺寸方向(图1的左右方向)移动。在杆11的长尺寸方向前端侧(右侧)设有活塞12。活塞12以其外周面沿着内筒5的内周面的方式移动。
内筒5内被活塞12分隔为活塞12后方侧的第1液室6和活塞12前端侧的第2液室7。活塞12设有圆筒状的磁铁21，在磁铁21内设有将第1液室6与第2液室7导通的磁铁内流路22(节流口)。在活塞12的磁铁内流路22的前头部设有阀13。在内筒5的前头部设有阀14。阀14能够使内筒5内和内筒5与外筒4之间的空间16导通。悬架装置1内的空间由油等液体充满。因此，在将阀13、14打开的状态下，通过使杆11在第1液室6与第2液室7之间位移，从而液体在磁铁内流路22、阀13、14中流通，活塞12活动，液压式减震器3能够产生液压。
悬架装置1还具备电动(电磁)减震器8。电动减震器8由磁铁21、线圈23等构成。电动减震器8作为电磁式的悬架发挥功能。即，在外筒4与内筒5之间设有圆筒状的线圈23(致动器)。通过向该线圈23通电而产生磁场，该磁场作用于磁铁21，从而能够使活塞12进一步来说能够使杆11沿着其轴向活动。在线圈23内设有线圈内通路24(节流口)。线圈内通路24将外筒4与内筒5之间的线圈23前后的空间16与空间17导通。
图2是内筒的长尺寸方向中央部的立体图。在内筒5中，在活塞12移动的位置的长尺寸方向中央部的内侧形成有以内筒5的长度方向为长尺寸方向的多道槽31。在活塞12经过该槽31时，活塞12也从槽31内通过，槽31内保持空间状态。即，槽31成为使活塞12的轴向两端侧的第1液室6与第2液室7连通的连通路。在图1、图2中，在内筒中央部32的区间形成有槽31。如图2所示，在内筒5中，内筒中央部32的两端部33的区间成为未形成槽的区域34。
从前述说明可知，电动减震器8为由磁铁21、线圈23等构成并使用从线性马达产生的磁力的电磁减震器。
接下来，说明本实施方式的作用。
图3A、图3B是说明实施方式1的悬架装置的作用的悬架装置的概念图。如图3A所示，在活塞12位于内筒中央部32的区间的情况下，活塞12位于内筒5的中央部。在该情况下，在阀13的位置处，阀13及槽31位于内筒5的径向。由于流体如箭头所示通过槽31，因此液压式减震器3的衰减力变得非常小。因而，在活塞12位于内筒中央部32的区间的情况下，对电动减震器8进行驱动。该内筒中央部32的区间为活塞12最频繁通过的区间。
如图3B所示，在活塞12位于未形成有两端部33的槽31的区间的情况下，活塞12位于内筒5的端部。在该情况下，在阀13的位置处，在内筒5的径向上有阀13而没有槽31。该情况下，流体通过阀13、14并如箭头所示流动，液压式减震器3的衰减力变得与常规的液压式减震器相同。即，在活塞12位于两端部33的情况下，液压式减震器3进行驱动。该两端部33为活塞仅偶尔通过的区间。
通过像这样仅使作为活塞12频繁移动的区间的内筒中央部32由电动减震器8驱动，从而能够削减磁铁21、线圈23等零部件、实现悬架装置1的低制造成本。
另外，由于仅在内筒5形成槽31即可，因此能够使悬架装置1整体小型化并简单地构成。
此外，通过利用设有磁铁21、线圈23的部位来设置磁铁内流路22(节流口)、线圈内通路24(节流口)，从而能够使电动减震器8整体的外形变窄。
此外，由于仅在内筒5形成槽31即可，因此能够以磁铁21与线圈23的距离很近的状态在内筒5与活塞12之间形成旁通通路(槽31)，电磁效率优良。
＜实施方式2＞
在本实施方式2中，主要说明与实施方式1不同的内筒，对相同的部件使用相同的附图标记并省略共通的内容。
图4是内筒的长尺寸方向中央部的立体图。如图1、图4所示，在内筒5中，活塞12移动的位置的长尺寸方向中央部(内筒中央部32)的内侧以使内筒5的内侧扩径的方式形成。在活塞12通过该扩径部41时，活塞12也不会从扩径部41的扩径的部分通过，扩径部41的扩径的部分内保持空间状态。即，扩径部41的扩径的部分成为用于使活塞12的轴向两端侧的第1液室6与第2液室7连通的连通路。在图1、图4中，在内筒中央部32的区间形成有扩径部41。如图4所示，在内筒5中，内筒中央部32的两端部33的区间成为未形成扩径部41的区域34。
接下来，说明本实施方式2的作用。
如图3A所示，在活塞12位于内筒中央部32的区间的情况下，活塞12位于内筒5的中央部位置。在该情况下，在阀13的位置处，阀13及扩径部41的扩径的部分位于内筒5的径向。由于流体如箭头所示通过扩径部41的扩径的部分，因此液压式减震器3的衰减力变得非常小。因而，在活塞12位于内筒中央部32的区间的情况下，对电动减震器8进行驱动。该内筒中央部32的区间为活塞12最频繁通过的区间。
如图3B所示，在活塞12位于两端部33的未形成有扩径部41的区间的情况下，活塞12位于内筒5的端部。在该情况下，在阀13的位置处，在内筒5的径向上有阀13而没有扩径部41。在该情况下，流体通过阀13、14并如箭头所示流动，液压式减震器3的衰减力变为与常规的液压式减震器相同。即，在活塞12位于两端部33的情况下，液压式减震器3进行驱动。该两端部33为活塞仅偶尔通过的区间。
通过像这样仅使作为活塞12频繁移动的区间的内筒中央部32由电动减震器8驱动，从而能够削减磁铁21、线圈23等零部件、实现悬架装置1的低制造成本。
另外，由于在内筒5形成槽31即可，因此能够使悬架装置1整体小型化并简单地构成。
通过利用设有磁铁21、线圈23的部位来设置磁铁内流路22(节流口)、线圈内通路24(节流口)，从而能够使电动减震器8整体的外形变窄。
此外，扩径部41整体地使内筒扩宽，能够增加液体的旁通量。另外，整体地使内筒扩宽，成形也简单，生产技术性提高。
需要说明的是，作为在内筒中央部32设置前述连通路的手段，不限定于第1实施方式的槽31的形成、第2实施方式的扩径部41的形成，也可以使用其他手段。
