Description

本発明は、車両のサスペンション構造に関するものである。   The present invention relates to a vehicle suspension structure.

一般に、トラック等の車両においては、車両の前後方向へ延びる一対のサイドレールが車両の幅方向へ所要間隔をあけて対向配置されたシャシフレームを備え、該シャシフレームの各サイドレール前部に、車両の前後方向へ延びるリーフスプリングの前後端を車両の幅方向へ延びるスプリングピンを介して取り付け、該リーフスプリングの中央部間に掛け渡すようにフロントアクスルを配設したサスペンション構造が採用されている。   In general, in a vehicle such as a truck, a pair of side rails extending in the front-rear direction of the vehicle includes a chassis frame disposed to face the vehicle in the width direction at a required interval, and the front side of each side rail of the chassis frame includes: A suspension structure is adopted in which front and rear ends of a leaf spring extending in the front-rear direction of the vehicle are attached via spring pins extending in the width direction of the vehicle, and a front axle is disposed so as to span between the center portions of the leaf springs. .

尚、前記シャシフレームの各サイドレール後部には、該各サイドレールの前部と同様に、車両の前後方向へ延びるリーフスプリングの前後端を車両の幅方向へ延びるスプリングピンを介して取り付け、該リーフスプリングの中央部間に掛け渡すようにリヤアクスルが配設されている。   The front and rear ends of leaf springs extending in the vehicle front-rear direction are attached to the rear portions of the side rails of the chassis frame via spring pins extending in the vehicle width direction, similar to the front portions of the side rails. A rear axle is disposed so as to span between the center portions of the leaf springs.

前記フロントアクスルの両側にはホイール及びタイヤが取り付けられ、該タイヤと路面との接地により直進性が保たれるが、操舵装置を操作して曲線走行を行った場合、車両の積荷の量並びに位置及び曲線走行の度合い等によって、前記フロントアクスルが取り付けられたリーフスプリングの前後端部をスプリングピンを介して支持するスプリングブラケットが路面に対し車幅方向へ大きく傾動することがある。   Wheels and tires are attached to both sides of the front axle, and the straightness is maintained by the ground contact between the tires and the road surface. Depending on the degree of curve traveling and the like, the spring bracket that supports the front and rear ends of the leaf spring to which the front axle is attached via the spring pin may be greatly tilted in the vehicle width direction with respect to the road surface.

これにより、前記シャシフレームが捩れることになり、該シャシフレームの復元力により自励振動が生じる。この自励振動は車体を振動させると共に、操舵装置を構成するステアリングが激しく振動する、いわゆるウォッブル（ｗｏｂｂｌｅ）現象を生じさせるという不具合がある。特にリーフスプリングの後端はシャックルを介してリヤ側のスプリングブラケットに取り付けられるため、該シャックルを支持するリヤ側のスプリングブラケットとサイドレールを含めたシャシフレームの全体の剛性が不足すると、前記ウォッブル現象を防止できなくなるという問題点があった。   As a result, the chassis frame is twisted and self-excited vibration is generated by the restoring force of the chassis frame. This self-excited vibration causes the vehicle body to vibrate and causes a so-called wobble phenomenon in which the steering wheel constituting the steering device vibrates violently. In particular, since the rear end of the leaf spring is attached to the rear spring bracket via a shackle, if the rigidity of the chassis frame including the rear spring bracket and the side rail supporting the shackle is insufficient, the wobble phenomenon There was a problem that it was impossible to prevent.

こうした問題点を解消するために、従来、シャシフレームを構成するサイドレール及びクロスメンバの板厚を増加させてシャシフレーム自体の剛性を高めることや、左右のリヤブラケットの間にサポートビームを架設することが行われていた。   In order to solve these problems, conventionally, the thickness of the side rail and cross member constituting the chassis frame is increased to increase the rigidity of the chassis frame itself, and a support beam is installed between the left and right rear brackets. Things were going on.

尚、左右のリヤブラケットの間にサポートビームを架設したサスペンションと関連する一般的技術水準を示すものとしては、例えば、特許文献１がある。   For example, Patent Document 1 shows a general technical level related to a suspension in which a support beam is installed between left and right rear brackets.

特開２００４−９８７７２号公報Japanese Patent Laid-Open No. 2004-98772

しかしながら、前述のように、シャシフレームを構成するサイドレール及びクロスメンバの板厚を増加させてシャシフレーム自体の剛性を高めるのでは、車両の重量増加やコストアップにつながるという不具合を有していた。又、特許文献１に開示された構造では、左右のリヤブラケット自体にサポートビームを架設しているため、リヤブラケットが大型化し、やはり車両の重量増加やコストアップは避けられなかった。   However, as described above, increasing the thickness of the side rails and cross members constituting the chassis frame to increase the rigidity of the chassis frame itself has the disadvantage of increasing the weight and cost of the vehicle. . Further, in the structure disclosed in Patent Document 1, since the support beams are installed on the left and right rear brackets themselves, the rear brackets are increased in size, and the increase in the weight and cost of the vehicle cannot be avoided.

本発明は、上記従来の問題点に鑑みてなしたもので、車両の重量増加やコストアップを最小限に抑えつつ、フロントアクスル用のリーフスプリングの支持剛性を高め、操縦安定性並びに振動特性向上を図り得る車両のサスペンション構造を提供しようとするものである。   The present invention has been made in view of the above-described conventional problems, and while increasing the weight and cost of the vehicle to a minimum, the support rigidity of the leaf spring for the front axle is increased, and the steering stability and vibration characteristics are improved. It is an object of the present invention to provide a vehicle suspension structure that can achieve the above.

本実施例の場合、前記リーフスプリング４前端におけるスプリングピン５の両端を連結する保持部１２Ａと、該保持部１２Ａ間をつなぐ連結部１２Ｂとを有する補強材１２を備えた点が特徴部分となっている。   In the case of the present embodiment, the feature is that the reinforcing member 12 having the holding portion 12A for connecting both ends of the spring pin 5 at the front end of the leaf spring 4 and the connecting portion 12B for connecting the holding portions 12A is provided. ing.

前記補強材１２は、図２及び図３に示す如く、前面側補強プレート１３と後面側補強プレート１４とを有しており、該前面側補強プレート１３は、前記リーフスプリング４との干渉を避けるよう二股状に形成され且つ先端部がスプリングピン５の両端前面側に当接される前面側二股状板部１３Ａと、該前面側二股状板部１３Ａ間をつなぐ前面側連結板部１３Ｂとを有し、前記後面側補強プレート１４は、前記リーフスプリング４との干渉を避けるよう二股状に形成され且つ先端部がスプリングピン５の両端後面側に当接される後面側二股状板部１４Ａと、該後面側二股状板部１４Ａ間をつなぐ後面側連結板部１４Ｂとを有している。前記前面側補強プレート１３及び後面側補強プレート１４は、複数（図３の例では四個）の円筒状のカラー１５を介装することにより、所要間隔ｓをあけて重ね合わされ、該カラー１５に対し締結部材１６としてのボルトを貫通させてナットを螺着することにより、前記前面側補強プレート１３及び後面側補強プレート１４を一体に締め付けるようにしてある。更に、前記前面側二股状板部１３Ａ及び後面側二股状板部１４Ａでスプリングピン５の両端部を前後から挟み付けた状態とし、この状態で、締結部材１７としてのボルトを貫通させてナットを螺着することにより、前記前面側補強プレート１３及び後面側補強プレート１４のスプリングピン５への取り付けを行うようにしてある。   As shown in FIGS. 2 and 3, the reinforcing member 12 has a front-side reinforcing plate 13 and a rear-side reinforcing plate 14, and the front-side reinforcing plate 13 avoids interference with the leaf spring 4. A front-side bifurcated plate portion 13A that is formed in a bifurcated shape and whose front ends are in contact with the front sides of both ends of the spring pin 5, and a front-side connecting plate portion 13B that connects the front-side bifurcated plate portion 13A. The rear surface side reinforcing plate 14 is formed in a bifurcated shape so as to avoid interference with the leaf spring 4, and the front surface side bifurcated plate portion 14 A with the front end portions being in contact with the rear surface sides of both ends of the spring pin 5. The rear side connecting plate portion 14B connecting the rear side bifurcated plate portions 14A. The front-side reinforcing plate 13 and the rear-side reinforcing plate 14 are overlapped with a predetermined interval s by interposing a plurality of (four in the example of FIG. 3) cylindrical collars 15. On the other hand, the front-side reinforcing plate 13 and the rear-side reinforcing plate 14 are integrally tightened by passing a bolt as the fastening member 16 and screwing a nut. Further, the both ends of the spring pin 5 are sandwiched from the front and rear by the front-side bifurcated plate portion 13A and the rear-side bifurcated plate portion 14A, and in this state, the bolts as the fastening members 17 are passed through the nuts. The front-side reinforcing plate 13 and the rear-side reinforcing plate 14 are attached to the spring pins 5 by screwing.

前記スプリングピン５は、図４及び図５に示す如く、両端部に、前記前面側二股状板部１３Ａ及び後面側二股状板部１４Ａの先端部が当接可能な平坦面１８を形成して取付部１９を設け、該取付部１９に、前記平坦面１８と直交する水平方向へ延び且つ前記締結部材１７としてのボルトが貫通可能な締結孔２０を穿設してある。   As shown in FIGS. 4 and 5, the spring pin 5 is formed with flat surfaces 18 at both ends that can contact the front end portions of the front side bifurcated plate portion 13A and the rear side bifurcated plate portion 14A. An attachment portion 19 is provided, and a fastening hole 20 extending in a horizontal direction perpendicular to the flat surface 18 and allowing a bolt as the fastening member 17 to pass through is provided in the attachment portion 19.

又、図２に示す如く、前記スプリングピン５の両端部における締結点Ｐ，Ｐを結ぶ直線ＨＬの中間部から垂下させた垂線ＶＬ上に、前記カラー１５を介した前面側補強プレート１３及び後面側補強プレート１４の締結点Ｑを設定してある。   Further, as shown in FIG. 2, the front-side reinforcing plate 13 and the rear surface via the collar 15 are placed on a perpendicular line VL suspended from an intermediate portion of a straight line HL connecting the fastening points P, P at both ends of the spring pin 5. The fastening point Q of the side reinforcing plate 14 is set.

次に、上記実施例の作用を説明する。   Next, the operation of the above embodiment will be described.

前述の如く、前記リーフスプリング４前端におけるスプリングピン５の両端を連結する保持部１２Ａと、該保持部１２Ａ間をつなぐ連結部１２Ｂとを有する補強材１２を備えるようにすると、前記補強材１２は、スプリングピン５の両端を保持部１２Ａで連結しつつ、該保持部１２Ａ間を連結部１２Ｂでつないでいるため、フロントアクスル７用のリーフスプリング４の支持剛性がきわめて有効に高められる。   As described above, when the reinforcing member 12 having the holding portion 12A for connecting both ends of the spring pin 5 at the front end of the leaf spring 4 and the connecting portion 12B for connecting the holding portions 12A is provided, the reinforcing member 12 is Since the both ends of the spring pin 5 are connected by the holding portion 12A and the holding portions 12A are connected by the connecting portion 12B, the support rigidity of the leaf spring 4 for the front axle 7 is extremely effectively increased.

しかも、前記補強材１２は、前面側二股状板部１３Ａ間を前面側連結板部１３Ｂでつないだ前面側補強プレート１３と、後面側二股状板部１４Ａ間を後面側連結板部１４Ｂでつないだ後面側補強プレート１４とをカラー１５を介して締結部材１６で一体に締め付ける構造としてあるため、前記補強材１２自体の重量が増加することを必要最小限に抑えることが可能となる。   Moreover, the reinforcing member 12 connects the front-side reinforcing plate 13 between the front-side bifurcated plate portions 13A with the front-side connecting plate portion 13B and the rear-side bifurcated plate portions 14A with the rear-side connecting plate portion 14B. Since the rear reinforcing plate 14 is integrally tightened with the fastening member 16 via the collar 15, it is possible to minimize the increase in the weight of the reinforcing member 12 itself.

この結果、従来のように、シャシフレーム３を構成するサイドレール２及びクロスメンバ１１の板厚を増加させてシャシフレーム３自体の剛性を高める必要がなくなり、車両１の重量増加を抑えつつ、コストアップを回避することが可能となる。   As a result, there is no need to increase the rigidity of the chassis frame 3 itself by increasing the plate thickness of the side rails 2 and the cross members 11 constituting the chassis frame 3 as in the prior art, while reducing the weight of the vehicle 1 and reducing the cost. It becomes possible to avoid up.

又、図２に示す如く、前記スプリングピン５の両端部における締結点Ｐ，Ｐを結ぶ直線ＨＬの中間部から垂下させた垂線ＶＬ上に、前記カラー１５を介した前面側補強プレート１３及び後面側補強プレート１４の締結点Ｑを設定してあるため、前記前面側補強プレート１３の前面側二股状板部１３Ａ及び後面側補強プレート１４の後面側二股状板部１４Ａがそれぞれ捩れたり、広がったり、或いはずれたりしてしまうことがなくなり、剛性を確保する上で非常に有効となる。   Further, as shown in FIG. 2, the front-side reinforcing plate 13 and the rear surface via the collar 15 are placed on a perpendicular line VL suspended from an intermediate portion of a straight line HL connecting the fastening points P, P at both ends of the spring pin 5. Since the fastening point Q of the side reinforcing plate 14 is set, the front side bifurcated plate portion 13A and the rear side bifurcated plate portion 14A of the front side reinforcing plate 13 are twisted or spread, respectively. In other words, it is very effective in securing rigidity.

こうして、車両１の重量増加やコストアップを最小限に抑えつつ、フロントアクスル７用のリーフスプリング４の支持剛性を高め、操縦安定性並びに振動特性向上を図り得る。   In this way, it is possible to increase the support rigidity of the leaf spring 4 for the front axle 7 while minimizing the increase in weight and cost of the vehicle 1, thereby improving the steering stability and vibration characteristics.

尚、本発明の車両のサスペンション構造は、上述の実施例にのみ限定されるものではなく、本発明の要旨を逸脱しない範囲内において種々変更を加え得ることは勿論である。   The suspension structure for a vehicle according to the present invention is not limited to the above-described embodiments, and various changes can be made without departing from the scope of the present invention.
