エンジンに取り付けた取付けブラケットにトルクロッドの一端部を連結し、
車体に前記トルクロッドの他端部を連結してあるトルクロッドの取付け構造に関する。 The present invention
Connect one end of the torque rod to the mounting bracket attached to the engine,
The present invention relates to a torque rod mounting structure in which the other end of the torque rod is connected to a vehicle body.

乗用車等の自動車に搭載されるエンジンは、通常、トランスミッション等を含めたユニットに構成されて車体に組み込まれ、防振マウントにより支持される。
この際、エンジンユニットのロール方向の動きや振動を抑制するために、該ユニットの一部（主に下部）が車輌走行方向とは反対方向に延びるトルクロッドにより車体に連結されている。 An engine mounted on an automobile such as a passenger car is usually configured as a unit including a transmission and the like, incorporated in a vehicle body, and supported by an anti-vibration mount.
At this time, in order to suppress the movement and vibration of the engine unit in the roll direction, a part (mainly the lower part) of the unit is connected to the vehicle body by a torque rod extending in a direction opposite to the vehicle traveling direction.

図１２〜図１４に従来のトルクロッドの取付け構造を示してある。図１２は従来のトルクロッドの取り付け構造の斜視図を示し、図１３は従来のトルクロッドの取り付け構造の平面図（上方からみた図）を示し、図１４は従来のトルクロッドの取り付け構造の分解斜視図を示している。 12 to 14 show a conventional torque rod mounting structure. 12 is a perspective view of a conventional torque rod mounting structure, FIG. 13 is a plan view (viewed from above) of the conventional torque rod mounting structure, and FIG. 14 is an exploded view of the conventional torque rod mounting structure. A perspective view is shown.

図１２〜図１４に示すように、従来のトルクロッド１００は、断面コの字状の本体部１３と、本体部１３の長手方向の一端部に外周面が溶接固着された円筒状の第１筒部７と、本体部１３の長手方向の他端部に外周面が溶接固着された円筒状の第２筒部２７と、第１筒部７に圧入内嵌された第１防振ブッシュＢ１と、第２筒部２７に圧入内嵌された第２防振ブッシュＢ２とから成り、前記取付けブラケット１は、エンジンに対する取り付け部４と、取付けボルト１９を挿通させるボルト挿通孔を備えたブッシュ支持壁３７とから成っていた。 As shown in FIGS. 12 to 14, the conventional torque rod 100 includes a main body portion 13 having a U-shaped cross section and a cylindrical first member whose outer peripheral surface is welded and fixed to one end portion in the longitudinal direction of the main body portion 13. The cylindrical portion 7, the cylindrical second cylindrical portion 27 whose outer peripheral surface is fixed by welding to the other end portion in the longitudinal direction of the main body portion 13, and the first vibration-isolating bush B 1 press-fitted into the first cylindrical portion 7. And a second vibration isolating bush B2 press-fitted into the second cylindrical portion 27, and the mounting bracket 1 has a bush support having a mounting portion 4 for the engine and a bolt insertion hole through which the mounting bolt 19 is inserted. It consisted of a wall 37.

詳述すると、前記第１筒部７に圧入内嵌された第１防振ブッシュＢ１は、第１内筒と、これを間隔を空けて取り囲む第１外筒と、第１内筒と第１外筒の間に介在し、第１内筒と第１内筒を連結する第１ゴム状弾性体とから成る。そして、振動が入力すると、第１ゴム状弾性体が弾性変形して第１外筒に対して第１内筒が相対移動し、これにより振動を吸収するようになっている。 More specifically, the first vibration-isolating bush B1 press-fitted into the first cylinder portion 7 includes a first inner cylinder, a first outer cylinder that surrounds the first inner cylinder with a space therebetween, a first inner cylinder, and a first inner cylinder. It comprises a first rubber-like elastic body that is interposed between the outer cylinders and connects the first inner cylinder and the first inner cylinder. When vibration is input, the first rubber-like elastic body is elastically deformed, and the first inner cylinder moves relative to the first outer cylinder, thereby absorbing the vibration.

前記第２筒部２７に圧入内嵌された第２防振ブッシュＢ２は、第１防振ブッシュＢ１と同様に、第２内筒と、これを間隔を空けて取り囲む第２外筒と、第２内筒と第２外筒の間に介在し、第２内筒と第２外筒を連結する第２ゴム状弾性体とから成る。
そして、振動の入力により第２ゴム状弾性体が弾性変形して第２外筒に対して第２内筒が相対移動し、これにより振動を吸収するようになっている。 Like the first vibration isolation bush B1, the second vibration isolation bush B2 press-fitted into the second cylinder portion 27 includes a second inner cylinder, a second outer cylinder that surrounds the second cylinder, and a second outer cylinder. The second rubber-like elastic body is interposed between the two inner cylinders and the second outer cylinder and connects the second inner cylinder and the second outer cylinder.
The second rubber-like elastic body is elastically deformed by the input of vibration, and the second inner cylinder moves relative to the second outer cylinder, thereby absorbing the vibration.

前記本体部１３は、上記のように断面コの字状にプレス成形されており、一対の互いに対向する側壁１４は、第１筒部７側が広幅で第２筒部２７側が幅狭の三角形状に形成されている。 The main body 13 is press-molded in a U-shaped cross section as described above, and the pair of opposite side walls 14 are triangular with the first cylinder 7 side wide and the second cylinder 27 side narrow. Is formed.

また、第１筒部７の軸芯（第１防振ブッシュＢ１の軸芯）と、第２筒部２７の軸芯（第２防振ブッシュＢ２の軸芯）とが、間隔を空けて互いに直交するように、第１筒部７と第２筒部２７の姿勢を設定してある（第１筒部７の軸芯と第２筒部２７の軸芯とが直交してないものもある）。 In addition, the axis of the first cylinder portion 7 (the axis of the first vibration isolation bush B1) and the axis of the second cylinder 27 (the axis of the second vibration isolation bush B2) are spaced apart from each other. The postures of the first tube portion 7 and the second tube portion 27 are set so as to be orthogonal to each other (the axis of the first tube portion 7 and the axis of the second tube portion 27 are not orthogonal). ).

そして、トルクロッド１００や取付けブラケット１とは別体のプレス成形された鉄製の挟持板３０を設け、取付けボルト１９を、ワッシャーと、挟持板３０の上端部側に形成したボルト挿通孔と、トルクロッド１００の第１防振ブッシュＢ１の第１内筒１１とに挿通させ、取付けブラケット１のブッシュ支持壁３７に形成した雌ねじ部に螺合締結し、トルクロッド１００の他端部の第２防振ブッシュＢ２を車体に連結してトルクロッドの取り付け構造を構成してあった。 A press-molded iron clamping plate 30 that is separate from the torque rod 100 and the mounting bracket 1 is provided, the mounting bolt 19 is a washer, a bolt insertion hole formed on the upper end side of the clamping plate 30, The rod 100 is inserted into the first inner cylinder 11 of the first anti-vibration bush B 1, and is screwed and fastened to a female thread portion formed on the bush support wall 37 of the mounting bracket 1, and a second anti-vibration at the other end of the torque rod 100. The vibration rod B2 is connected to the vehicle body to constitute a torque rod mounting structure.

前記挟持板３０は上下方向に細長い四角形状に形成されるとともに、横断面コの字状に形成されている（前記挟持板３０が三角形状に形成されているものもある）。つまり、挟持板３０の幅方向の両端部にそれぞれ上下方向に沿うリブを備えている。また、下端部を取付けブラケット１側に折曲してある。これにより、挟持板３０の強度をより強くしてある。 The sandwiching plate 30 is formed in a rectangular shape that is elongated in the vertical direction, and is formed in a U-shape in cross section (some of the sandwiching plates 30 are formed in a triangular shape). That is, the ribs along the vertical direction are provided at both ends in the width direction of the sandwiching plate 30. Moreover, the lower end part is bent to the mounting bracket 1 side. Thereby, the intensity | strength of the clamping board 30 is made stronger.

前記挟持板３０の下端部にもボルト挿通孔が形成されている。そして、前記取付けボルトよりも短い第２の取付けボルト３１を前記ワッシャーに挿通させ、前記取付けブラケット１の下端部に形成した雌ねじ部に、前記第２の取付けボルト３１を螺合し締結してある。 Bolt insertion holes are also formed in the lower end portion of the clamping plate 30. Then, a second mounting bolt 31 shorter than the mounting bolt is inserted through the washer, and the second mounting bolt 31 is screwed and fastened to a female thread portion formed at the lower end portion of the mounting bracket 1. .

符号５は、エンジンに対する取付けボルトを挿通させるためのボルト挿通孔であり、取付けブラケット１の長手方向に長い長孔に形成されて、前記長手方向に所定の間隔を空けて並んでいる。 Reference numeral 5 denotes a bolt insertion hole for allowing a mounting bolt to be inserted into the engine. The bolt insertion hole is formed as a long hole in the longitudinal direction of the mounting bracket 1 and is arranged at a predetermined interval in the longitudinal direction.

上記従来の構造によれば、トルクロッドの取り付け構造が、主としてトルクロッド１００と取付けブラケット１と挟持板３０との３部材から成るために、部品点数が多くて各部材の組付け作業に手間がかかり、製作コストが高かった。また、挟持板３０が鉄製であるために重量も重くなっていた。
本発明は上記実状に鑑みて成されたもので、その目的は、部品点数を少なくすることができて組付け作業を簡単化でき、製作コストを低廉化でき、軽量化できるトルクロッドの取り付け構造を提供する点にある。 According to the above-described conventional structure, the torque rod mounting structure is mainly composed of the three members of the torque rod 100, the mounting bracket 1, and the clamping plate 30, so that the number of parts is large and the work for assembling each member is troublesome. It took a lot of money and the production cost was high. Further, since the sandwiching plate 30 is made of iron, the weight is also heavy.
The present invention has been made in view of the above circumstances, and its purpose is to reduce the number of parts, simplify the assembly work, reduce the manufacturing cost, and reduce the weight, and a torque rod mounting structure. Is to provide
