Description

本発明は、中央の作用導入体と外側の支持リングに密に結合しているエラストマー製のばね体からなるエラストマー製のばねを有する液圧式マウントであって、エラストマー製のばねと駆動可能な液圧式ピストンとの間に配置されているとともに作動液を収容している作動室を備え、この作動室が支持リング内の少なくとも一つの絞り流路を介して補償室と接続され、この補償室が、中央の作用導入体と支持リングに密に結合しているエラストマーベローズによって密閉されている液圧式マウントに関する。   The present invention relates to a hydraulic mount having an elastomeric spring composed of an elastomeric spring body that is tightly coupled to a central action introducing body and an outer support ring, the elastomeric spring and a drivable fluid. A working chamber disposed between the pressure piston and containing the working fluid, the working chamber being connected to the compensation chamber via at least one throttle channel in the support ring, And a hydraulic mount sealed by an elastomer bellows which is tightly coupled to a central working introducer and a support ring.

上記のような形式の液圧式マウントは、そのばね作用がエラストマー製のばね体の変形によって得られるばねマウント要素として使用される。通常、大きな体積のゴム部材として製造されるエラストマー製のばね体は、この場合には支持ばね及び伸張ばねとして機能する。エラストマー製のばねは、作動室に収容されている作動液に作用を及ぼす。作動液は、少なくとも一つの絞り流路を介して、作動室から、事実上圧力を受けることなく、容積を、すなわちある体積の作動液を受容するエラストマーベローズによって密閉されている補償室に流入可能である。   A hydraulic mount of the type described above is used as a spring mount element whose spring action is obtained by deformation of an elastomeric spring body. Normally, an elastomeric spring body manufactured as a large volume rubber member functions in this case as a support spring and an extension spring. The elastomer spring acts on the hydraulic fluid contained in the working chamber. The hydraulic fluid can flow from the working chamber through the at least one throttle channel into the compensation chamber, which is sealed by an elastomer bellows that accepts a volume of hydraulic fluid, with virtually no pressure. It is.

エラストマー製のばねの運動によって、作動室の容量が拡大又は縮小する。作動室内の圧力上昇によって、一方でエラストマー製のばね体が膨張、伸張される。他方で、作動液が絞り流路を通って補償室に移動する。これにより、振動する系の減衰が達成される。   The movement of the elastomeric spring increases or decreases the capacity of the working chamber. Due to the pressure increase in the working chamber, on the other hand, the elastomeric spring body is expanded and extended. On the other hand, the hydraulic fluid moves through the throttle channel to the compensation chamber. This achieves damping of the vibrating system.

通常、電磁石により駆動される液圧式ピストンによって、振動の伝達を適切に抑制するか、又は少なくとも十分に低減させるやり方で、作動室内の圧力変化を生じさせることができる。したがって、このような液圧式マウントは能動的液圧式マウントとも称される。   Typically, hydraulic pistons driven by electromagnets can cause pressure changes in the working chamber in a manner that adequately suppresses or at least sufficiently reduces vibration transmission. Such hydraulic mounts are therefore also referred to as active hydraulic mounts.

冒頭に記載した上位概念による公知の液圧式マウントの場合には、エラストマー製のばね体が、その外周部で支持リングに加硫接合され、その内側縁部で力を受ける作用導入体に加硫接合されている(例えば特許文献1参照)。作動室と補償室の密封のために、別個の密封措置が講じられなければならない。特に、この場合には、液圧式マウントの複数の接合継目における密封が必要である。
独国特許第3918753号公報
In the case of the known hydraulic mount according to the superordinate concept described at the beginning, the elastomeric spring body is vulcanized and joined to the support ring at its outer peripheral part and vulcanized to the action introducing body that receives force at its inner edge. It joins (for example, refer patent document 1). Separate sealing measures must be taken to seal the working and compensation chambers. In particular, in this case, sealing at a plurality of joint seams of the hydraulic mount is necessary.
German Patent No. 3987553

したがって本発明は、冒頭に記載した上位概念による液圧式マウントを、作動室と補償室の密封に関する製造及び組立の手間を本質的に単純化し、コストを低減し、かつ作動室と補償室の密封をより確実に形成できるように発展させることを課題とする。   Accordingly, the present invention provides a hydraulic mount according to the superordinate concept described at the outset, which substantially simplifies the manufacturing and assembly effort associated with sealing the working chamber and compensation chamber, reduces costs, and seals the working chamber and compensation chamber. It is an issue to develop so that can be formed more reliably.

上記課題は、本発明によれば、エラストマー製のばね体を、補償室を密閉するエラストマーベローズと一体に形成し、かつ支持リングを液圧式ピストンに密に結合しているエラストマー膜と一体に形成することによって解決される。   According to the present invention, the above-described problem is that an elastomer spring body is formed integrally with an elastomer bellows that seals a compensation chamber, and a support ring is formed integrally with an elastomer film that is tightly coupled to a hydraulic piston. It is solved by doing.

外側に向かっての補償室の密封、及び液圧式ピストンの駆動領域内への作動液の流出に対する密封、ならびに補償室の密閉が、一連の製造工程で製造される一体の部材、即ちエラストマーベローズが一体に接続され、かつエラストマー膜が一体に接続されているエラストマー製のばね体によって形成、もたらされる。   The sealing of the compensation chamber toward the outside and the sealing against the outflow of hydraulic fluid into the drive area of the hydraulic piston, and the sealing of the compensation chamber are performed by an integral member, that is, an elastomer bellows, manufactured in a series of manufacturing processes. Formed and provided by an elastomeric spring body connected together and an elastomeric membrane connected together.

Is assumed to be connected. The elastomer film forms a seal with the elastomer spring body against the outside of the working chamber.

絞り流路は、支持リングと、これに接するエラストマー膜の壁部とを介して延伸する少なくとも一つの絞り穿孔として形成されていることが好ましい。少なくとも一つの、好ましくは複数の絞り穿孔を形成することで十分であるから、この絞り流路の形成は本質的に簡略化される。   The throttle channel is preferably formed as at least one throttle hole extending through the support ring and the wall portion of the elastomer film in contact with the support ring. Since it is sufficient to form at least one, preferably a plurality of throttling perforations, the formation of this throttling channel is essentially simplified.

更なる有利な態様は、更なる従属請求項の対象である。   Further advantageous embodiments are the subject of further dependent claims.

補償室を密閉するエラストマーベローズが、その外縁部に密封隆起部を有し、この外縁部の密封隆起部が支持リングとホルダリングの間に密に収容されていることが好ましい。   The elastomer bellows that seals the compensation chamber preferably has a sealing ridge at its outer edge, and the sealing ridge at the outer edge is tightly accommodated between the support ring and the holder ring.

エラストマー膜の環形状の膜部が、その内縁部に密封隆起部を有し、この内縁部の密封隆起部が液圧式ピストンとクランプリングの間に密に収容されていることが好ましい。   The ring-shaped membrane part of the elastomeric membrane preferably has a sealing ridge at its inner edge, and the sealing ridge at the inner edge is preferably tightly accommodated between the hydraulic piston and the clamp ring.

エラストマー膜の環形状の膜部が、液圧式ピストンを支持リングに結合する皿ばねの作動室の側の面に接していることが好ましい。   It is preferable that the ring-shaped membrane portion of the elastomer membrane is in contact with the surface of the disk spring on the side of the working chamber that couples the hydraulic piston to the support ring.

エラストマー製のばね体が、中央の作用導入体に加硫接合され、かつ支持リングに加硫接合されていることが好ましい。   It is preferable that the elastomer spring body is vulcanized and joined to the central action introducing body and vulcanized and joined to the support ring.

液圧式ピストンが、皿ばねとこの皿ばねに対して並列接続されている圧縮ばねとによって位置付けられていることが好ましい。   The hydraulic piston is preferably positioned by a disc spring and a compression spring connected in parallel to the disc spring.

本発明は、中央の作用導入体と外側の支持リングに密に結合しているエラストマー製のばね体からなるエラストマー製のばねを有する液圧式マウントであって、当該エラストマー製のばねと駆動可能な液圧式ピストンとの間に配置されているとともに作動液を収容している作動室を備え、この作動室が前記支持リング内の少なくとも一つの絞り流路を介して補償室と接続され、この補償室が、前記中央の作用導入体と前記支持リングに密に結合しているエラストマーベローズによって密閉されている液圧式マウントに関する。液圧式マウントが、そのばね作用がエラストマー製のばね体の変形によって得られるばねマウント要素として使用され、通常、大きな体積のゴム部材として製造されているエラストマー製のばね体が、この場合には支持ばね及び伸張ばねとして機能し、エラストマー製のばねが、作動室に収容されている作動液に作用を及ぼし、作動液が、少なくとも一つの絞り流路を介して、作動室から、事実上圧力を受けることなくある体積の作動液を受容するエラストマーベローズによって密閉されている補償室に流入可能であり、さらにエラストマー製のばね体が、補償室を密閉するエラストマーベローズと一体に形成され、かつ支持リングを液圧式ピストンに密に結合するエラストマー膜と一体に形成されている。   The present invention is a hydraulic mount having an elastomeric spring consisting of an elastomeric spring body that is tightly coupled to a central action introducer and an outer support ring, which is drivable with the elastomeric spring. A working chamber disposed between the hydraulic piston and containing the working fluid, the working chamber being connected to the compensation chamber via at least one throttle channel in the support ring; The invention relates to a hydraulic mount in which a chamber is sealed by an elastomer bellows which is tightly coupled to the central working introducer and the support ring. A hydraulic mount is used as a spring mount element whose spring action is obtained by deformation of an elastomeric spring body, which is usually supported by an elastomeric spring body, which in this case is manufactured as a large volume rubber member. Acting as a spring and extension spring, an elastomeric spring acts on the hydraulic fluid contained in the hydraulic chamber, and the hydraulic fluid effectively exerts pressure from the hydraulic chamber via at least one throttle channel. It is possible to flow into a compensation chamber sealed by an elastomer bellows that receives a volume of hydraulic fluid without being received, and an elastomeric spring body is integrally formed with the elastomer bellows sealing the compensation chamber, and a support ring Is integrally formed with an elastomer film that is tightly coupled to the hydraulic piston.

このような構成によって、作動室と補償室の密封に関する製造及び組立の手間を本質的に単純化することができ、それによってコストを低減することができ、かつ作動室と補償室の密封をより確実に形成することが可能となる。   Such a configuration can substantially simplify the manufacturing and assembly effort associated with sealing the working chamber and the compensation chamber, thereby reducing costs and making the sealing between the working chamber and the compensation chamber more efficient. It becomes possible to form reliably.

さらに本発明を、添付の図面を参照する実施例に基づいて詳説する。   The invention will be further described on the basis of embodiments with reference to the accompanying drawings.

図1に示す液圧式マウントはエラストマー製のばね1を有し、例えばゴムから製造されているエラストマー製のばね体2が、中央の、金属製の作用導入体3に加硫接合され、かつこの作用導入体3を取り囲んでいる支持リング4に加硫接合されている。作用導入体3により、外部からの力が液圧式マウントに導入される。   The hydraulic mount shown in FIG. 1 has an elastomeric spring 1, for example, an elastomeric spring body 2 made of rubber is vulcanized and joined to a metal action introducing body 3 at the center. It is vulcanized and joined to a support ring 4 surrounding the action introducing body 3. The action introducing body 3 introduces external force into the hydraulic mount.

エラストマー製のばね1の下方には作動液で満たされている作動室5が配置され、この作動室は円板形状の液圧式ピストン6によってその下側が密閉されている。液圧式ピストン6は、環形状の皿ばね7を介して支持リング4と結合している。液圧式ピストン6は、強磁性体材料、例えば鋼から製造され、電磁コイル8に対する電機子を形成し、この電磁コイル8は、液圧式ピストン6の下方のコイルホルダ内に配置され、かつコイルホルダを介して支持リング4と結合している。   A working chamber 5 filled with a working fluid is disposed below the elastomer spring 1, and the working chamber is hermetically sealed by a disk-shaped hydraulic piston 6. The hydraulic piston 6 is coupled to the support ring 4 via an annular disc spring 7. The hydraulic piston 6 is manufactured from a ferromagnetic material, for example steel, and forms an armature for the electromagnetic coil 8, which is disposed in a coil holder below the hydraulic piston 6 and is a coil holder. It couple | bonds with the support ring 4 via.

螺旋状圧縮ばね10が、液圧式ピストン6をコイルホルダ9に対して支持している。したがって液圧式ピストン6は、皿ばね7と螺旋状圧縮ばね10とによって軸方向で位置付けられている。   A helical compression spring 10 supports the hydraulic piston 6 against the coil holder 9. Accordingly, the hydraulic piston 6 is positioned in the axial direction by the disc spring 7 and the helical compression spring 10.

したがって、電磁石又は電磁コイル8から発せされる磁力は、ほぼ静止している場合には、皿ばね7のばね力と圧縮ばね10のばね力の和に等しい。   Therefore, the magnetic force generated from the electromagnet or electromagnetic coil 8 is equal to the sum of the spring force of the disc spring 7 and the spring force of the compression spring 10 when it is substantially stationary.

液圧式ピストン6の予荷重は、皿ばね7と圧縮コイルばね10の並列接続によってもたらされる。液圧式ピストン6の運動により皿ばねのほぼ平坦な中間動作位置が得られるように、かつ摩損作用のある相対運動が皿ばね7の縁部にほとんど生じないように、動作点は皿ばね7と螺旋状ばねとの設計により調整可能である。   The preload of the hydraulic piston 6 is brought about by the parallel connection of the disc spring 7 and the compression coil spring 10. The operating point is the same as that of the disc spring 7 so that the movement of the hydraulic piston 6 provides a substantially flat intermediate operating position of the disc spring, and so that there is almost no abrasive relative movement at the edge of the disc spring 7. Adjustable by design with spiral spring.

エラストマー製のばね体2の上方には、作動液で満たされた補償室11が同様に形成され、この補償室はその外側に向かう側を、容易に変形可能なエラストマーベローズ12によって密閉されているので、その結果、補償室11は圧力を受けることなく、十分な量の作動液を受容することができる。   A compensation chamber 11 filled with hydraulic fluid is similarly formed above the elastomer spring body 2, and this compensation chamber is sealed on its outer side by an elastomer bellows 12 that can be easily deformed. As a result, the compensation chamber 11 can receive a sufficient amount of hydraulic fluid without receiving pressure.

特に図2に明瞭に示すように、エラストマー製のばね体2は、作動室5とは反対側であって、その内側の縁部でエラストマーベローズ12と一体に結合している。補償室11を密閉するエラストマーベローズ12は、その外縁部に密封隆起部13を有し、この外縁部の密封隆起部13は、取り付けられた状態(図1)で、支持リング4とホルダリング14の間に密に収容されている。   As clearly shown in FIG. 2 in particular, the spring body 2 made of elastomer is integrally connected to the elastomer bellows 12 at the inner edge on the side opposite to the working chamber 5. The elastomer bellows 12 that seals the compensation chamber 11 has a sealing ridge 13 at its outer edge, and the sealing ridge 13 at the outer edge is attached to the support ring 4 and the holder ring 14 (FIG. 1). It is tightly housed between.

エラストマー製のばね体2は、作動室5の側の縁部で、その外周部においてエラストマー膜15と一体に結合している。このエラストマー膜15は、作動室側で支持リング4に隣接する壁部16を有し、この壁部16に環形状の膜部17が接続し、この膜部17は、液圧式ピストン6を支持リング4に結合させる皿ばね7の作動室側の面に接する。   The elastomer spring body 2 is integrally joined to the elastomer film 15 at the outer peripheral portion at the edge of the working chamber 5 side. The elastomer membrane 15 has a wall portion 16 adjacent to the support ring 4 on the working chamber side, and an annular membrane portion 17 is connected to the wall portion 16, and this membrane portion 17 supports the hydraulic piston 6. It contacts the working chamber side surface of the disc spring 7 coupled to the ring 4.

エラストマー膜15の環形状の膜部17は、その内縁部に密閉隆起部18を有し、この内縁部の密封隆起部18は、取り付けられた状態(図1)で、液圧式ピストン6とクランプリング19の間に密に収容されている。   The ring-shaped membrane portion 17 of the elastomeric membrane 15 has a sealing ridge 18 at its inner edge, and the sealing ridge 18 at the inner edge is attached to the hydraulic piston 6 and clamped (FIG. 1). Contained tightly between rings 19.

作動室5は、複数の絞り穿孔20によって形成されている絞り流路を介して補償室11と接続している。これらの絞り穿孔20は、支持リング4とこれに接するエラストマー膜15の壁部16とを通って延伸している。   The working chamber 5 is connected to the compensation chamber 11 through a throttle channel formed by a plurality of throttle holes 20. These throttle perforations 20 extend through the support ring 4 and the wall 16 of the elastomeric membrane 15 in contact therewith.
