Description

本発明は、車両のエンジンの防振金具として使用されるトルクロッドに関する。   The present invention relates to a torque rod used as a vibration isolator for a vehicle engine.

一般にトルクロッドは、内筒と外筒との間にゴム弾性体が介装され、車両のエンジン側と車体側に取り付けられる一対のブッシュと、これら一対のブッシュを連結する連結ロッドとを有し、車両のエンジン側と車体側とに跨って介装され、エンジンのロール方向及び前後方向の変位を規制し、併せてエンジン側と車体側との振動絶縁を行うようになっている。   Generally, the torque rod has a pair of bushes attached to the engine side and the vehicle body side of a vehicle, and a connecting rod that connects the pair of bushes, with a rubber elastic body interposed between an inner cylinder and an outer cylinder. It is interposed between the engine side and the vehicle body side of the vehicle, regulates the displacement of the engine in the roll direction and the front-rear direction, and also performs vibration isolation between the engine side and the vehicle body side.

このようなトルクロッドにおいては、連結ロッドを外筒とは別に製造して溶接接合することが必要であり、構成部品点数が多くなり、加工工数が多く、コスト高になってしまうこととなる。   In such a torque rod, it is necessary to manufacture and weld the connecting rod separately from the outer cylinder, which increases the number of components, increases the number of processing steps, and increases the cost.

そのため、連結部を板状に形成し、その両端部に外筒を一体に形成することにより、加工の工程数を少なくして、コストを安価にする提案もなされている（特許文献１参照）。
特開２００５−１６３８４４号公報 Therefore, a proposal has been made to reduce the number of processing steps and reduce the cost by forming the connecting portion in a plate shape and integrally forming the outer cylinder at both ends thereof (see Patent Document 1). .
JP 2005-163844 A

このようなトルクロッドにあっては、各車種ごとに取付け長さが異なる場合、長さの異なるトルクロッドを新設しなければならないという問題があった。   In such a torque rod, when the installation length is different for each vehicle type, there is a problem that a torque rod having a different length must be newly provided.

本発明の目的は、各車種ごとに取付け長さが異なる場合であっても、新設することなく、各車種に対応することのできるトルクロッドを提供することにある。   An object of the present invention is to provide a torque rod that can be adapted to each vehicle type without being newly installed even when the mounting length is different for each vehicle type.

前記目的を達成するため、本発明のトルクロッドは、内筒と外筒との間にゴム弾性体が介装され、車両のエンジン側と車体側に取り付けられる一対のブッシュと、これら一対のブッシュを連結する連結部とを有するトルクロッドにおいて、
前記連結部は、各ブッシュの外筒より突出して設けられた一対の筒状連結部材からなり、一方の筒状連結部材が他方の筒状連結部材内に差込み可能にされていることを特徴とする。 In order to achieve the above object, a torque rod according to the present invention includes a pair of bushes mounted on the engine side and the vehicle body side of a vehicle, with a rubber elastic body interposed between the inner cylinder and the outer cylinder, and the pair of bushes. A torque rod having a connecting portion for connecting
The connecting portion includes a pair of cylindrical connecting members provided so as to protrude from the outer cylinder of each bush, and one of the cylindrical connecting members can be inserted into the other cylindrical connecting member. To do.

本発明によれば、連結部を各ブッシュの外筒より突出して設けられた一対の筒状連結部材にて構成し、一方の筒状連結部材を他方の筒状連結部材内に差込み可能にすることで、各車種ごとに取付け長さが異なる場合であっても、一対の筒状連結部材をスライドさせてラップ代を調整して溶接することにより、一対のブッシュ間のピッチを自由に設定することができるため、他のトルクロッドを新設することなく、各車種の取付け長さに対応させることができ、しかも、連結部が筒状となるため、連結部の強度を保つことができる。   According to the present invention, the connecting portion is constituted by a pair of cylindrical connecting members provided so as to protrude from the outer cylinder of each bush, and one cylindrical connecting member can be inserted into the other cylindrical connecting member. Thus, even if the mounting length is different for each vehicle type, the pitch between the pair of bushes can be set freely by sliding the pair of cylindrical connecting members and adjusting the lap allowance for welding. Therefore, it is possible to correspond to the mounting length of each vehicle type without newly installing another torque rod, and furthermore, since the connecting portion has a cylindrical shape, the strength of the connecting portion can be maintained.

また、一対の筒状連結部材を連結する構成となっているため、取り付け時にブッシュを回転させることで、ブッシュの角度も自由に設定することができることとなる。   Moreover, since it becomes the structure which connects a pair of cylindrical connection members, the angle of a bush can also be freely set by rotating a bush at the time of attachment.

本発明においては、前記各筒状連結部材は、それぞれのブッシュの外筒と一体に曲折形成されるようにすることができる。   In the present invention, each of the cylindrical connecting members can be bent integrally with the outer cylinder of each bush.

このような構成とすることにより、従来の連結ロッドを廃止でき、部品点数を削減でき、加工工数も削減して、コストを削減することが可能となる。   By adopting such a configuration, the conventional connecting rod can be eliminated, the number of parts can be reduced, the number of processing steps can be reduced, and the cost can be reduced.

以下、本発明の実施の形態について、図面を参照して説明する。   Embodiments of the present invention will be described below with reference to the drawings.

図１〜図４は、本発明の一実施の形態にかかるトルクロッドを示す図である。   1-4 is a figure which shows the torque rod concerning one Embodiment of this invention.

図１は、本実施の形態にかかるトルクロッドの車両への取付け状態を示す斜視図で、この車両は車体側に取り付けられたサスペンションメンバ１０上に、エンジンマウント１２を介して、エンジン１４及びトランスミッション１６を含むパワーユニット１８が弾性支持された状態となっている。   FIG. 1 is a perspective view showing a state in which a torque rod according to the present embodiment is attached to a vehicle. This vehicle has an engine 14 and a transmission mounted on a suspension member 10 attached to the vehicle body side via an engine mount 12. The power unit 18 including 16 is elastically supported.

そして、エンジン１４の下部と、サスペンションメンバ１０のセンターフレーム２０とに跨ってトルクロッド２２が取り付けられている。   A torque rod 22 is attached across the lower part of the engine 14 and the center frame 20 of the suspension member 10.

このトルクロッド２２は、一対の大小のブッシュ２４、２６と、これらのブッシュ２４、２６を連結する連結部２８とを有し、大きなブッシュ２４がセンターフレーム２０に取り付けられ、小さなブッシュ２６がエンジン１４の下部に取り付けられるようになっている。   The torque rod 22 has a pair of large and small bushes 24, 26 and a connecting portion 28 that connects the bushes 24, 26. The large bush 24 is attached to the center frame 20, and the small bush 26 is the engine 14. It can be attached to the bottom of the.

このトルクロッド２２の詳細を、図２の拡大正面図、図３の拡大平面図及び図４の拡大分解斜視図に基づいて説明する。   Details of the torque rod 22 will be described based on an enlarged front view of FIG. 2, an enlarged plan view of FIG. 3, and an enlarged exploded perspective view of FIG.

大きなブッシュ２４は、内筒３０と外筒３２との間に円筒状のゴム弾性体３４が介装され、それらが加硫接着により一体化された状態となっており、内筒３０がセンターフレーム２０にボルト・ナットで締結固定されて大きなブッシュ２４がセンターフレーム２０に弾性的に結合された状態となっている。   In the large bush 24, a cylindrical rubber elastic body 34 is interposed between the inner cylinder 30 and the outer cylinder 32, and these are integrated by vulcanization adhesion. The large bush 24 is fastened and fixed to the center frame 20 by a bolt and a nut, and is elastically coupled to the center frame 20.

小さなブッシュ２６は、内筒３６と外筒３８との間に円筒状のゴム弾性体４０が介装され、それらが加硫接着により一体化された状態となっており、内筒３６がエンジン１４にボルト・ナットで締結固定されて、小さなブッシュ２６がエンジン１４に弾性的に結合された状態となっている。   In the small bush 26, a cylindrical rubber elastic body 40 is interposed between the inner cylinder 36 and the outer cylinder 38, and these are integrated by vulcanization adhesion. The small bush 26 is elastically coupled to the engine 14 by fastening with bolts and nuts.

連結部２８は、一対の筒状連結部材４２、４４に分割形成されたもので、一方の筒状連結部材４２は大きなブッシュ２４の外筒３２側面より突出して設けられ、他方の筒状連結部材４４は小さなブッシュ２６の外筒３８側面より突出して設けられている。   The connecting portion 28 is divided into a pair of cylindrical connecting members 42, 44. One cylindrical connecting member 42 is provided so as to protrude from the side surface of the outer cylinder 32 of the large bush 24, and the other cylindrical connecting member. 44 is provided to protrude from the side surface of the outer cylinder 38 of the small bush 26.

一方の筒状連結部材４２は、大きなブッシュ２４の外筒３２と一体に曲折形成され、他方の筒状連結部材４４は、小さなブッシュ２６の外筒３８と一体に曲折形成されている。   One cylindrical connecting member 42 is bent integrally with the outer cylinder 32 of the large bush 24, and the other cylindrical connecting member 44 is bent integrally with the outer cylinder 38 of the small bush 26.

また、大きなブッシュ２４側筒状連結部材４２内径が小さなブッシュ２６側の筒状連結部材４４の外径と略一致するように、大きなブッシュ２４側の筒状連結部材４２の径が大きく、小さなブッシュ２６側の筒状連結部材４４の径が小さく形成されている。   In addition, the large bushing 24 side cylindrical coupling member 42 has a large diameter and a small bushing so that the inner diameter of the large bushing 24 side cylindrical coupling member 42 substantially matches the outer diameter of the small bushing 26 side cylindrical coupling member 44. The diameter of the cylindrical connecting member 44 on the 26th side is formed small.

そして、筒状連結部材４４が筒状連結部材４２内に差込まれて、筒状連結部材４２、４４同士が軸方向にスライド可能、かつ、軸回りに回転可能にされている。   The cylindrical connecting member 44 is inserted into the cylindrical connecting member 42 so that the cylindrical connecting members 42 and 44 can slide in the axial direction and rotate about the axis.

このように、連結部２８を各ブッシュ２４、２６の外筒３２、３８より突出して設けられた一対の筒状連結部材４２、４４にて構成し、筒状連結部材４４を筒状連結部材４２内に差込み可能にすることで、各車種ごとに取付け長さが異なる場合であっても、一対の筒状連結部材４２、４４をスライドさせてラップ代を調整した後、溶接することにより、一対のブッシュ２４、２６間のピッチＰ（図３参照）を自由に設定することができる。   As described above, the connecting portion 28 is constituted by a pair of cylindrical connecting members 42 and 44 provided so as to protrude from the outer cylinders 32 and 38 of the bushes 24 and 26, and the cylindrical connecting member 44 is configured as the cylindrical connecting member 42. Even if the mounting length is different for each vehicle type by allowing it to be inserted in, a pair of cylindrical connecting members 42, 44 are slid to adjust the lap allowance, and then welded. The pitch P between the bushes 24 and 26 (see FIG. 3) can be freely set.

したがって、他のトルクロッドを新設することなく、各車種の取付け長さに容易に対応させることができる。   Therefore, it is possible to easily correspond to the mounting length of each vehicle type without newly installing another torque rod.

しかも、連結部２８が筒状となるため、連結部２８の強度を保つことができる。   Moreover, since the connecting portion 28 has a cylindrical shape, the strength of the connecting portion 28 can be maintained.

また、連結部２８が一対の筒状連結部材４２、４４を差込み連結する構成となっているため、図４に示すように、取り付け時にブッシュ２４または２６を回転させることで、ブッシュ２４、２６の角度も自由に設定することができることとなる。   Further, since the connecting portion 28 is configured to insert and connect the pair of cylindrical connecting members 42 and 44, as shown in FIG. 4, by rotating the bush 24 or 26 at the time of attachment, The angle can also be set freely.

さらに、各筒状連結部材４２、４４は、それぞれのブッシュ２４、２６の外筒３２、３８と一体に曲折形成されるようにしているため、従来の連結ロッドを廃止でき、部品点数を削減でき、加工工数も削減して、コストを削減することが可能となる。   Furthermore, since each cylindrical connection member 42 and 44 is bent together with the outer cylinders 32 and 38 of the respective bushes 24 and 26, the conventional connection rod can be eliminated and the number of parts can be reduced. It is possible to reduce costs by reducing the number of processing steps.
