Description

この発明は、中心軸線の下方に向けて拡径するテーパ状をなす外筒と、外筒の内周側に配置した内筒と、該外筒と内筒とを連結するとともに、外筒の外周面を被覆する弾性部材とを具えてなり、車輪側から延びるストラットロッドの上端部を、前記内筒の内部に貫通させ、底面に貫通孔を設けた倒立皿状形状の車体側パネルの内側に、前記外筒を嵌め合わせて使用に供されるストラットマウントに関するものであり、とくに、車体側パネルとストラットロッドとの間に配設した際の、ストラットマウントの、車体の左右方向および前後方向の少なくとも一方のばね定数を所要に応じて変更可能とし、車両の乗り心地性等を向上させる技術を提案するものである。   The present invention connects an outer cylinder having a tapered shape whose diameter increases toward the lower side of the central axis, an inner cylinder disposed on the inner peripheral side of the outer cylinder, the outer cylinder and the inner cylinder, An inner side of an inverted dish-shaped vehicle body side panel comprising an elastic member that covers the outer peripheral surface, the upper end portion of the strut rod extending from the wheel side is penetrated into the inner cylinder, and a through hole is provided in the bottom surface In particular, the present invention relates to a strut mount that is used by fitting the outer cylinder, and in particular, when the strut mount is disposed between the vehicle body side panel and the strut rod, the left and right and front and rear directions of the vehicle body. The present invention proposes a technique that can change at least one of the spring constants as required to improve the riding comfort of the vehicle.

この種のストラットマウントは、たとえば、特許文献１、２に記載されたものがある。
その一例としての、図５に示すストラットマウント５１は、中心軸線の下方に向けて次第に拡径する外筒５２と、外筒５２の内側に配置した内筒５３と、外筒５２および内筒５３の相互を連結するとともに、外筒５２の外周面および内筒５３の内周面のそれぞれを被覆する弾性部材５４とを具えてなるものである。 This type of strut mount is disclosed in Patent Documents 1 and 2, for example.
As an example, a strut mount 51 shown in FIG. 5 includes an outer cylinder 52 that gradually increases in diameter toward the lower side of the central axis, an inner cylinder 53 that is disposed inside the outer cylinder 52, an outer cylinder 52, and an inner cylinder 53. And an elastic member 54 that covers each of the outer peripheral surface of the outer cylinder 52 and the inner peripheral surface of the inner cylinder 53.

かかるストラットマウント５１を車体に取付けるに当っては、内筒５３の内部に、車輪側に配設される、図示しないショックアブソーバの一部をなすストラットロッド５５を貫通させて配置するとともに、外筒５２を、それの外周面を被覆する弾性部材部分を介して、車体側パネル５６の内側に嵌め合わせる。   When the strut mount 51 is attached to the vehicle body, a strut rod 55 that is part of a shock absorber (not shown) that is disposed on the wheel side is disposed inside the inner cylinder 53 so as to penetrate the outer cylinder. 52 is fitted inside the vehicle body side panel 56 through an elastic member portion covering the outer peripheral surface thereof.

車輪側と車体側との間に、このように介装したストラットマウント５１は、車両の走行時に、車輪が路面から受ける上下方向の入力の大部分を、ショックアブソーバと、その周囲を取り囲むコイルスプリング５８とで吸収するとともに、それらで吸収できなかった入力部分を、ストラットマウント５１の、主として弾性部材５４の剪断変形により吸収して、車輪側からの入力振動の、車体側への伝達を抑制する懸架装置として機能する。   The strut mount 51 interposed between the wheel side and the vehicle body side in this way is a coil spring that surrounds the shock absorber and most of the vertical input received by the wheel from the road surface when the vehicle is running. 58, and the input portion that could not be absorbed by them is absorbed mainly by the shear deformation of the elastic member 54 of the strut mount 51 to suppress the transmission of the input vibration from the wheel side to the vehicle body side. Functions as a suspension device.

ところで、ストラットマウントは、一般的に、車両の乗り心地性および操縦安定性の双方を両立するためには、車両の上下方向（図の上下方向）の入力に対して軟らかいばね特性を発揮するとともに、車両の左右方向もしくは前後方向（図の左右方向もしくは奥行き方向）、またはそれらの両方向の入力に対して、硬いばね特性を発揮できるものであることが望ましい。
ここで、図５に例示するようなストラットマウント５１によれば、車体側パネル５６に一体的に連結固定されていないことから、車両の上下方向の入力に対して軟らかいばね特性を発揮して、この入力による振動を有効に抑制でき、車両の乗り心地性を向上することができる。 By the way, the strut mount generally exhibits a soft spring characteristic with respect to the input in the vertical direction of the vehicle (the vertical direction in the figure) in order to achieve both the ride comfort and the handling stability of the vehicle. It is desirable that a hard spring characteristic can be exhibited with respect to an input in the left-right direction or the front-rear direction of the vehicle (the left-right direction or the depth direction in the figure) or both directions.
Here, according to the strut mount 51 as illustrated in FIG. 5, since it is not integrally connected and fixed to the vehicle body side panel 56, it exhibits a spring characteristic that is soft with respect to the vehicle vertical input, Vibration due to this input can be effectively suppressed, and the ride comfort of the vehicle can be improved.

しかるに、上記のストラットマウント５１では、車両の前後方向および左右方向のばね定数は、弾性部材５４の、図の左右方向および／または奥行き方向の、主には、圧縮および引張り剛性のみで決まるため、車両の上下方向のばね定数を変化させることなく、前後方向および／または左右方向のばね定数をさらに大きくすることは困難である。   However, in the above-described strut mount 51, the spring constant in the front-rear direction and the left-right direction of the vehicle is determined solely by the compression and tensile rigidity of the elastic member 54 in the left-right direction and / or the depth direction in the figure. It is difficult to further increase the spring constant in the front-rear direction and / or the left-right direction without changing the spring constant in the vertical direction of the vehicle.

しかも、このようなストラットマウント５１は、車体側パネル５６に嵌め合わせて取付けられることから、剛性部材である外筒５２および内筒５３の形状が、車体への取付け姿勢でそれらの周囲に位置する部材の形状、とくに車体側パネル５６の形状に大きく依存することになって、外筒５２、内筒５３の形状変更のいかんによっては、ストラットマウント５１の、上述した、車両の上下方向のばね特性などの他の特性に影響を与えるおそれがあった。   In addition, since such a strut mount 51 is fitted and attached to the vehicle body side panel 56, the shapes of the outer cylinder 52 and the inner cylinder 53, which are rigid members, are positioned around them in the mounting posture to the vehicle body. Depending on the shape of the member, in particular, the shape of the vehicle body side panel 56, depending on the shape change of the outer cylinder 52 and the inner cylinder 53, the spring characteristics of the strut mount 51 in the vertical direction of the vehicle described above. Other characteristics may be affected.

この発明は、従来技術が抱えるこのような問題を解決することを課題とするものであり、それの目的とするところは、車両の優れた乗り心地性を維持してなお、車両の前後方向および／または左右方向のばね定数を所要に応じて高めることにより、車両の操縦安定性を向上させ、また、それらの前後方向と左右方向との相互間で適正なばね特性を実現して、要求される性能を十分に満足させることができるストラットマウントを提供するにある。   The present invention has an object to solve such problems of the prior art, and the object of the present invention is to maintain the excellent riding comfort of the vehicle while maintaining the longitudinal direction of the vehicle and By increasing the spring constant in the left / right direction as required, the handling stability of the vehicle is improved, and proper spring characteristics are realized between the front / rear direction and the left / right direction. It is an object of the present invention to provide a strut mount that can sufficiently satisfy the required performance.

この発明のストラットマウントは、中心軸線の下方に向けて拡径するテーパ状をなす外筒と、外筒の内周側に配置した内筒と、該外筒と内筒とを連結するとともに、外筒の外周面を被覆する弾性部材とを具えてなり、車輪側から延びるストラットロッドの上端部を、前記内筒の内部に貫通させるとともに、底面に貫通孔を設けた倒立皿状形状の車体側パネルの内側に、前記外筒を嵌め合わせて使用に供されるストラットマウントにおいて、外筒の下端部で、車体側パネルへの嵌合姿勢で車体の左右方向および前後方向の少なくとも一方向と対応する位置のそれぞれに、下方に向けて突出し、弾性部材の軸線方向の圧縮姿勢の下での水平変位で内筒に、直接的に、または弾性部材等を介して間接的に当接する一対の突出部を設けてなるものである。   The strut mount of the present invention connects the outer cylinder and the inner cylinder, the outer cylinder having a tapered shape whose diameter increases toward the lower side of the central axis, the inner cylinder disposed on the inner peripheral side of the outer cylinder, An inverted dish-shaped vehicle body comprising an elastic member that covers the outer peripheral surface of the outer cylinder, the upper end of the strut rod extending from the wheel side penetrating the inside of the inner cylinder, and having a through hole in the bottom surface In the strut mount that is used for fitting the outer cylinder inside the side panel, at the lower end of the outer cylinder, at least one of the left-right direction and the front-rear direction of the vehicle body in the fitting posture to the vehicle body side panel A pair of protrusions projecting downward at the corresponding positions and abutting directly or indirectly via the elastic member or the like on the inner cylinder by horizontal displacement under the axial compression posture of the elastic member Protrusions are provided .

ここで好ましくは、外筒の一対の突出部の内表面、および、内筒の、前記突出部との当接部分の少なくとも一方を、外筒と内筒とを連結する前記弾性部材で被覆する。   Preferably, at least one of the inner surface of the pair of projecting portions of the outer cylinder and the contact portion of the inner cylinder with the projecting portion is covered with the elastic member that connects the outer cylinder and the inner cylinder. .

この発明のストラットマウントによれば、外筒の下端部で、車体の左右方向および前後方向の少なくとも一方向と対応する位置のそれぞれに、下方に向けて突出する突出部を設け、その突出部を、弾性部材の軸線方向の圧縮姿勢の下での水平変位で内筒に当接させることにより、一対の突出部が、それらを設けた位置と対応する、車体の左右方向および／または前後方向への内筒の相対変位を抑制するべく機能することになるので、ストラットマウントの内筒への、一対の突出部の位置と対応する方向の入力に対するばね定数が大きくなり、この結果として、車両の操縦安定性を向上させることができる。
しかもこれによれば、一対の突出部を、外筒の下端部から下方に向けて突出させたことから、ストラットマウントと、車体側パネルとの嵌合、ないしはストラットロッドとの連結に影響を及ぼすことがなく、主として車両の上下方向のばね特性に基く、車両の乗り心地性の低下を招くおそれがない。 According to the strut mount of the present invention, the lower end portion of the outer cylinder is provided with a protruding portion that protrudes downward at each of the positions corresponding to at least one of the left-right direction and the front-rear direction of the vehicle body. When the elastic member is brought into contact with the inner cylinder with a horizontal displacement under the axial compression posture of the elastic member, the pair of projecting portions correspond to the positions where they are provided in the left-right direction and / or the front-rear direction of the vehicle body. Therefore, the spring constant for the input in the direction corresponding to the position of the pair of protrusions to the inner cylinder of the strut mount is increased. Steering stability can be improved.
In addition, according to this, since the pair of projecting portions project downward from the lower end portion of the outer cylinder, the fitting between the strut mount and the vehicle body side panel or the connection with the strut rod is affected. There is no possibility that the ride comfort of the vehicle will be lowered mainly based on the vertical spring characteristics of the vehicle.

また、一対の突出部を、外筒の下端部の、車両の前後方向または左右方向のいずれか一方と対応する位置にのみ設けることによって、それらの方向のいずれか一方のばね定数のみを大きくすることができるため、要求される性能に応じて適正なばね特性を発揮させることができる。   Further, by providing the pair of projecting portions only at positions corresponding to either the front-rear direction or the left-right direction of the vehicle at the lower end portion of the outer cylinder, only the spring constant in either direction is increased. Therefore, an appropriate spring characteristic can be exhibited according to the required performance.

ここで、外筒の一対の突出部の内表面、および、内筒の、前記突出部との当接部分の少なくとも一方を、外筒と内筒とを連結する弾性部材で被覆したときは、その弾性部材部分により、外筒の突出部と内筒との当接による衝撃をやわらげることができ、またこの場合は、突出部と内筒との間に別個独立の弾性材料を介装配置する場合と比べて、ストラットマウントの製造コストを減少させることができる。   Here, when covering at least one of the inner surface of the pair of projecting portions of the outer cylinder and the contact portion of the inner cylinder with the projecting portion with an elastic member connecting the outer cylinder and the inner cylinder, The elastic member portion can reduce the impact caused by the contact between the protruding portion of the outer cylinder and the inner cylinder. In this case, a separate and independent elastic material is interposed between the protruding portion and the inner cylinder. Compared to the case, the manufacturing cost of the strut mount can be reduced.

以下に図面を参照しつつ、この発明の実施の形態について説明する。
図１に例示するストラットマウント１は、中心軸線Ｃの下方に向けて次第に拡径するテーパ状をなす外筒２と、外筒２の内周側に配置した内筒３と、外筒２と内筒３とを連結するとともに、外筒２の外周面および、図では内筒３の内周面のそれぞれを被覆する弾性部材４とを具える。 Embodiments of the present invention will be described below with reference to the drawings.
A strut mount 1 illustrated in FIG. 1 includes an outer cylinder 2 having a tapered shape that gradually increases in diameter toward a lower side of a central axis C, an inner cylinder 3 disposed on the inner peripheral side of the outer cylinder 2, an outer cylinder 2, While connecting with the inner cylinder 3, it has the outer peripheral surface of the outer cylinder 2, and the elastic member 4 which coat | covers each of the inner peripheral surface of the inner cylinder 3 in the figure.

ここで、外筒２は、金属材料などの剛性材料により形成し、中心軸線Ｃの上方側から下方側に向けて外径および内径がともに拡径するテーパ状をなす。
一方、内筒３は、外筒２と同様に剛性材料により形成し、図に示すところでは、中心軸線Ｃ方向の略中央域に、全周にわたって外周側に向けて膨出する肩部３ｂを形成してなる、頂壁に開口を設けた略ハット形状をなす。 Here, the outer cylinder 2 is formed of a rigid material such as a metal material, and has a tapered shape in which both the outer diameter and the inner diameter increase from the upper side to the lower side of the central axis C.
On the other hand, the inner cylinder 3 is formed of a rigid material in the same manner as the outer cylinder 2, and, as shown in the drawing, a shoulder 3b that bulges toward the outer circumference over the entire circumference in the substantially central region in the central axis C direction. It has a substantially hat shape with an opening formed in the top wall.

また、図に示すところでは、外筒２と内筒３とを連結する弾性部材４によって、外筒２の外周面および、内筒３の内周面のそれぞれを被覆するものとする。このようにすれば、外筒２と、それの外周側に配置する、図示しない車体側パネル、ならびに、内筒３と、それの内側に挿入配置する、これも図示しないストラットロッドのそれぞれを、弾性部材部分を介して当接させることができる。   Further, as shown in the drawing, the outer peripheral surface of the outer cylinder 2 and the inner peripheral surface of the inner cylinder 3 are covered with an elastic member 4 that connects the outer cylinder 2 and the inner cylinder 3. If it does in this way, each of the outer cylinder 2 and the vehicle body side panel which is arrange | positioned in the outer peripheral side of it, and the inner cylinder 3, and the strut rod which is also inserted and arranged inside this, respectively, It can be contacted via the elastic member portion.

そしてここでは、図２に示す、弾性部材４の軸線方向の圧縮姿勢の下で、図では弾性部材部分を介して、外筒２の、直径方向に対抗する二箇所に、外筒２の下端部から下方へ突出し、水平面内で内筒３に重なり合う一対の突出部２ａを設ける。この突出部２ａは、図３に外筒２のみを取出して平面図で示すように、外筒２の下端部の、車体への取付け姿勢で、たとえば車両の左右方向（図３の左右方向）と対応する位置のそれぞれに形成する。
これによれば、ストラットマウント１を、車体に取付けて使用に供する場合、たとえば、突出部２ａと内筒３との、弾性部材部分を介した当接に基き、車両の左右方向のばね定数が大きくなるので、車両の操縦安定性能を有効に向上させることができる。 Here, under the compression posture in the axial direction of the elastic member 4 shown in FIG. 2, the lower end of the outer cylinder 2 is disposed at two locations opposite to the diameter direction of the outer cylinder 2 through the elastic member portion in the figure. A pair of projecting portions 2a that project downward from the portion and overlap the inner cylinder 3 in a horizontal plane are provided. As shown in the plan view of FIG. 3, only the outer cylinder 2 is taken out, and the projecting portion 2a is, for example, the vehicle left-right direction (left-right direction in FIG. 3) in the mounting posture of the lower end of the outer cylinder 2 to the vehicle body. And corresponding positions.
According to this, when the strut mount 1 is attached to the vehicle body and used for use, for example, the spring constant in the lateral direction of the vehicle is based on the contact between the protruding portion 2a and the inner cylinder 3 via the elastic member portion. Since it becomes large, the steering stability performance of a vehicle can be improved effectively.

なおここで、突出部２ａは、外筒２の下端から、中心軸線Ｃと平行に突出形成する場合だけに限定されるものではなく、突出部２ａを、たとえば、外筒２の下端部から、中心軸線Ｃに近接させながら下方に突出させることができる他、中心軸線Ｃから離隔させながら下方へ突出させることもできる。   Here, the protruding portion 2a is not limited to the case where the protruding portion 2a is formed to protrude in parallel with the central axis C from the lower end of the outer cylinder 2, and the protruding portion 2a is, for example, from the lower end portion of the outer cylinder 2. In addition to being able to project downward while being close to the central axis C, it is also possible to project downward while being spaced apart from the central axis C.

このような突出部２ａは、図１、２に示すように、剛性材料からなる外筒２と一体的に形成することが、ストラットマウント１の製造コスト等の観点から好ましく、金属材料により外筒２を形成する場合には、たとえば、素材シートを、図３に示す形状にプレス加工することによって、突出部２ａを一体的に具えた外筒２を形成することができる。   As shown in FIGS. 1 and 2, it is preferable that the protruding portion 2 a is formed integrally with the outer cylinder 2 made of a rigid material from the viewpoint of the manufacturing cost of the strut mount 1. In the case of forming 2, for example, by pressing a material sheet into a shape shown in FIG. 3, the outer cylinder 2 integrally including the protruding portion 2 a can be formed.

ここで、車両の左右方向ではなく前後方向のばね定数を大きくする必要がある場合は、図示は省略するが、突出部を、車両の前後方向（図３の上下方向）と対応する位置のそれぞれに形成することで対処することができる。
また、同様に図示を省略するが、車両の左右方向および前後方向の双方のばね定数を大きくする場合は、車両の左右方向および前後方向の各方向と対応するそれぞれ位置に、二対の突出部を形成することもできる。 Here, when it is necessary to increase the spring constant in the front-rear direction instead of the left-right direction of the vehicle, the illustration is omitted, but the projecting portions are respectively located at positions corresponding to the front-rear direction of the vehicle (up-down direction in FIG. 3). It can be dealt with by forming in.
Similarly, although not shown in the drawings, when the spring constants in both the left-right direction and the front-rear direction of the vehicle are increased, two pairs of protrusions are provided at positions corresponding to the left-right direction and the front-rear direction of the vehicle, respectively. Can also be formed.

なお、図１、２に示すところでは、突出部２ａおよび、内筒３の、突出部２ａが当接する部分３ａのそれぞれを、弾性部材４で被覆していることから、外筒２の突出部２ａと内筒部分３ａとの当接衝撃を、被覆弾性部材部分によって緩和することができる。
但し、単に、車両の左右方向および／または前後方向のばね定数を大きくするためだけには、突出部２ａ、内筒部分３ａを弾性部材４で被覆することは必須の構成ではない。 1 and 2, the protruding portion 2a and the portion 3a of the inner cylinder 3 with which the protruding portion 2a abuts are covered with the elastic member 4, so that the protruding portion of the outer cylinder 2 is provided. The contact impact between 2a and the inner cylinder portion 3a can be mitigated by the covered elastic member portion.
However, in order to simply increase the spring constant in the left-right direction and / or the front-rear direction of the vehicle, it is not essential to cover the protruding portion 2 a and the inner cylinder portion 3 a with the elastic member 4.

ここにおいて、図４に拡大断面図で示す突出部２ａの、中心軸線Ｃと平行をなす方向への突出長さＬや、突出部２ａないしは内筒部分３ａを被覆する弾性部材部分の厚みなどは、ストラットマウント１を取付ける車体の重量や要求性能などに応じて適宜変更することができる。   Here, the protruding length L of the protruding portion 2a shown in the enlarged sectional view of FIG. 4 in the direction parallel to the central axis C, the thickness of the elastic member portion covering the protruding portion 2a or the inner cylinder portion 3a, etc. The strut mount 1 can be changed as appropriate according to the weight of the vehicle body to which the strut mount 1 is attached and the required performance.

これらを変更することによって、たとえば、ストラットマウント１に車体重量が作用した状態で、図２に示すように、突出部２ａが弾性部材部分を介して、内筒３に、水平方向で完全に接触するものとすることができ、この場合は、ストラットマウント１を使用に供するに際して、突出部２ａを被覆する弾性部材部分と、内筒の当接部分３ａを被覆する弾性部材部分との衝接による異音の発生なしに、車両の左右方向のばね定数を常に大きくし、車両の操縦安定性能を向上させることができる。   By changing these, for example, when the weight of the vehicle body acts on the strut mount 1, as shown in FIG. 2, the protrusion 2 a completely contacts the inner cylinder 3 in the horizontal direction via the elastic member portion. In this case, when the strut mount 1 is used, the elastic member portion covering the protruding portion 2a and the elastic member portion covering the contact portion 3a of the inner cylinder are brought into contact with each other. Without generating abnormal noise, the spring constant in the left-right direction of the vehicle can always be increased, and the steering stability performance of the vehicle can be improved.

また、突出長さＬや、被覆弾性部材部分の厚みなどを変更することにより、車体重量の作用下で、図４に破線で示すように、突出部２ａを被覆する弾性部材部分と、内筒の当接部分３ａを被覆する弾性部材部分とが近接するものとすることもできる。
これによれば、突出部２ａは、車両の通常の走行においてはほとんど機能しないが、ストラットマウント１の、内筒３の内側に挿入配置される、図示しないストラットロッドから大きなこじり力等が入力された際に、内筒３の、車両の左右方向への相対変位を規制するストッパとして機能することになる。 Further, by changing the protruding length L, the thickness of the covering elastic member portion, etc., the elastic member portion covering the protruding portion 2a and the inner cylinder as shown by the broken line in FIG. It is also possible that the elastic member part covering the contact part 3a is close.
According to this, the projecting portion 2a hardly functions in normal traveling of the vehicle, but a large squeezing force or the like is input from a strut rod (not shown) that is inserted and disposed inside the inner cylinder 3 of the strut mount 1. In this case, the inner cylinder 3 functions as a stopper for restricting the relative displacement of the vehicle in the left-right direction.
