Description

本発明は、車両の荷重伝達システムに関する。 The present invention relates to a vehicle load transfer system.

小型商用車（ＬＣＶ）やトラック等の車体フレームとキャブが別体に構成されて、キャブが車体フレームの上に載置されているフレーム構造の車両においては、車両が前方衝突したときに、この衝突時の衝撃力は車両の前方両端に向って加わり、車体フレームとキャブの両側の前方接合部から中央側に向かって斜め後方向に向かってキャブの床面に伝わる。しかしながら、従来のキャブの床面構造では、縦補強部材（縦フレーム）が床面の前後方向に配置されており、この衝撃力によりキャブの客室の床面が変形する虞がある。 In a vehicle with a frame structure in which the body frame and cab are separately configured, such as a light commercial vehicle (LCV) or truck, and the cab is placed on the body frame, this occurs when the vehicle collides forward. The impact force at the time of a collision is applied toward both front ends of the vehicle and is transmitted to the floor surface of the cab diagonally backward toward the center from the front joints on both sides of the vehicle body frame and the cab. However, in the conventional cab floor structure, vertical reinforcing members (vertical frames) are arranged in the front-rear direction of the floor surface, and this impact force may deform the floor surface of the cabin of the cab.

ここで、車体フレームにおいて、車体に平行に設けられた左右一対のフロントサイドフレームの近傍に、このフロントサイドフレームの補強材である縦フレームを設けるとともに、この縦フレームを平面視でフロントサイドフレームに対して傾斜させて、その後部がその前部よりもそれぞれ車幅方向の内側に位置するようにした車体前部構造が提案されている（例えば、特許文献１参照）。 Here, in the vehicle body frame, a vertical frame that is a reinforcing material of the front side frame is provided in the vicinity of a pair of left and right front side frames provided parallel to the vehicle body, and this vertical frame is used as a front side frame in a plan view. On the other hand, a vehicle body front structure has been proposed in which the rear portion is inclined to be located inside the front portion in the vehicle width direction (see, for example, Patent Document 1).

ところで、上記の車体前部構造は、キャブの搭載位置より前方の車体フレームに係る構造であるので、車両の前方衝突時におけるキャブの床面の変形には関与しない。 By the way, since the vehicle body front structure is related to the vehicle body frame in front of the cab mounting position, it does not participate in the deformation of the cab floor surface at the time of a frontal collision of the vehicle.

本発明の目的は、キャブと車体フレームが別体で形成される構造の車両において、車両の前方衝突時における客室の床面の変形を抑制することができる車両の荷重伝達システムを提供する。 An object of the present invention is to provide a vehicle load transmission system capable of suppressing deformation of the floor surface of a passenger compartment at the time of a frontal collision of the vehicle in a vehicle having a structure in which the cab and the vehicle body frame are formed separately.

上記の目的を達成するための本発明の車両の荷重伝達システムは、車両の前後方向に延在する車体フレームの前方に該車体フレームとは別体のキャブを載置して構成される車両の荷重伝達システムにおいて、前記キャブの客室の床面の前方両端に配設され、前記キャブおよび前記車体フレームの側方を接合する接合部と、前記床面の幅方向に延在し、前記キャブの重量を支持するための補強材である横強度部材と、前記キャブの床面に沿って前記接合部から後方の中央内側に向かって配設された強度部材と、前記床面の幅方向中央の下方に前記床面の前後方向に延在して配設される動力伝達用装置の収納部と、を備え、この収納部の上方に位置する前記床面がその周辺の前記床面に対して上方に盛り上がるように構成されて、前記横強度部材が前記収納部を跨りながら配設されて、前記強度部材は、前記接合部と前記収納部および前記横強度部材の交差する部位である交差部とを接続して配設される。 The vehicle load transmission system of the present invention for achieving the above object is a vehicle configured by mounting a cab separate from the vehicle body frame in front of the vehicle body frame extending in the front-rear direction of the vehicle. In the load transmission system, the cab is provided at both front ends of the floor surface of the passenger compartment of the cab, and extends in the width direction of the floor surface with a joint portion that joins the cab and the side of the vehicle body frame. A lateral strength member which is a reinforcing material for supporting the weight, a strength member arranged along the floor surface of the cab from the joint toward the rear center inside, and a center in the width direction of the floor surface. A storage portion for a power transmission device extending downward in the front-rear direction of the floor surface is provided, and the floor surface located above the storage portion is provided with respect to the floor surface around the storage portion. The lateral strength member is arranged so as to swell upward so as to straddle the storage portion, and the strength member is an intersection portion where the joint portion, the storage portion, and the lateral strength member intersect. And are connected and arranged .

車体フレームとキャブを別体で構成する車両では、前方で衝突したときにこの衝突時の衝撃力が車体フレームを介してこの車体フレームとキャブの側方の接合部から中央内側に向かってキャブの床面に加わり、キャブの床面が座屈して変形する。 In a vehicle in which the vehicle body frame and the cab are separated from each other, when a collision occurs in front of the vehicle, the impact force at the time of the collision is applied to the cab from the lateral joint between the vehicle body frame and the cab toward the inside of the center via the vehicle body frame. It joins the floor and the floor of the cab buckles and deforms.

本発明の車両の荷重伝達システムによれば、強度部材をキャブの床面に沿って側方の接合部から後方の中央内側に向かって配設するので、このキャブの床面の変形を抑制することができる。 According to the vehicle load transmission system of the present invention, the strength members are arranged along the floor surface of the cab from the lateral joint toward the rear center inside, so that the deformation of the floor surface of the cab is suppressed. be able to.

キャブと車体フレームの関係を示す側面図である。It is a side view which shows the relationship between a cab and a body frame. 図１のキャブと車体フレームの関係を車体の底面から見た図で、本発明の第１実施形態を示す図である。FIG. 1 is a view of the relationship between the cab and the vehicle body frame in FIG. 1 as viewed from the bottom surface of the vehicle body, and is a diagram showing a first embodiment of the present invention. 図２より車体フレームを除いた図である。It is the figure which excluded the body frame from FIG. 本発明の第２実施形態を示す、車体フレームを除いた図である。It is a figure which shows the 2nd Embodiment of this invention, excluding the body frame.

以下、本発明に係る第１実施形態の車両の荷重伝達システムについて、図面を参照しながら説明する。なお、図１〜図３では、車両の前後方向、車両の幅方向、車両の上下方向をそれぞれ矢印Ｘ、Ｙ、Ｚで示している。また、図１では、車両の前方部分のみを図示し、キャブ１０の後方に配設される荷台や荷台を支持する車体フレーム２０の部分は省略している。また、図２では、車体フレーム２０がエンジンルーム１１より前方に突き出しているが、この突き出している部分には、バンパー（図示しない）が配設される。 Hereinafter, the vehicle load transmission system of the first embodiment according to the present invention will be described with reference to the drawings. In FIGS. 1 to 3, the front-rear direction of the vehicle, the width direction of the vehicle, and the vertical direction of the vehicle are indicated by arrows X, Y, and Z, respectively. Further, in FIG. 1, only the front portion of the vehicle is shown, and the loading platform arranged behind the cab 10 and the portion of the vehicle body frame 20 that supports the loading platform are omitted. Further, in FIG. 2, the vehicle body frame 20 projects forward from the engine room 11, and a bumper (not shown) is arranged at the projecting portion.

図１に示すように、本発明の対象となる車両の荷重伝達システム１は、車両の前後方向（Ｘ方向）に延在する車体フレーム２０の前側部分に、この車体フレーム２０とは別体のキャブ１０を載置して構成される車両、例えば、小型商用車（ＬＣＶ）やトラック等の車両に対して適用されるシステムである。この車両では、車両が他の車両や障害物等と前方衝突したときに、この衝突時の衝撃力が車両の前方から車体フレーム２０の両側の強度部材に加わる。 As shown in FIG. 1, the vehicle load transmission system 1 which is the object of the present invention has a front portion of the vehicle body frame 20 extending in the front-rear direction (X direction) of the vehicle, which is separate from the vehicle body frame 20. It is a system applied to a vehicle configured by mounting a cab 10, for example, a vehicle such as a light commercial vehicle (LCV) or a truck. In this vehicle, when the vehicle collides forward with another vehicle, an obstacle, or the like, the impact force at the time of the collision is applied to the strength members on both sides of the vehicle body frame 20 from the front of the vehicle.

キャブ１０は、車両の前方より順に、エンジンルーム１１、ダッシュパネル１２、客室１３を備えて構成される。エンジンルーム１１は、車両の走行用の動力源であるエンジン（内燃機関、図示しない）を収納する部位である。ダッシュパネル１２は、エンジンルーム１１と客室１３を区画する部位である。この客室１３の床面（フロアパネル）１４においては、図２に示すように、その下方にトランスミッションやプロペラシャフト（図示しない）等の車両の動力伝達に関わる動力伝達用装置を配設するために、直下に動力伝達用装置を配設する部分の高さ（右斜線部）を他の部分の高さより高くしている。言い換えれば、フロアパネル１４が他の平板部分のフロアパネル１４より盛り上がる凸形状の収納部（トンネル）１５に動力伝達用装置を配設している。 The cab 10 includes an engine room 11, a dash panel 12, and a cabin 13 in this order from the front of the vehicle. The engine room 11 is a portion for accommodating an engine (internal combustion engine, not shown) which is a power source for traveling a vehicle. The dash panel 12 is a portion that separates the engine room 11 and the guest room 13. On the floor surface (floor panel) 14 of the cabin 13, as shown in FIG. 2, in order to dispose a power transmission device related to vehicle power transmission such as a transmission and a propeller shaft (not shown) below the floor surface (floor panel) 14. , The height of the part where the power transmission device is arranged directly underneath (right shaded part) is made higher than the height of the other parts. In other words, the power transmission device is arranged in the convex storage portion (tunnel) 15 in which the floor panel 14 is raised from the floor panel 14 of the other flat plate portion.

図２に示すように、キャブ１０はフロアパネル１４の前方両端に備えたキャブマウント（前方接合部）２１で車体フレーム２０と接続される。なお、図２では、キャブ１０と車体フレーム２０の接続位置について、キャブマウント２１のみを図示しているが、その他のキャブマウントについては省略している。また、エンジンルーム１１及びダッシュパネル１２と車体フレーム２０の接続位置についても省略している。 As shown in FIG. 2, the cab 10 is connected to the vehicle body frame 20 by cab mounts (front joints) 21 provided at both front ends of the floor panel 14. In FIG. 2, only the cab mount 21 is shown for the connection position between the cab 10 and the vehicle body frame 20, but the other cab mounts are omitted. Further, the connection positions of the engine room 11, the dash panel 12, and the vehicle body frame 20 are also omitted.

本発明では、図２、図３に示すように、キャブ１０のフロアパネル（床面）１４に沿って、キャブ１０と車体フレーム２０の側方の接合部２１から後方の中央内側に向かって強度部材（アンダーフロアレインフォース）３０を配設して構成する。つまり、車両の前方に衝撃力Ｆが加わったときに、フロアパネル１４にて衝撃力（荷重）Ｆが加わって座屈する部分Ｂ（図３のみ図示、図２では煩雑さを回避するため省略）に対して、この円弧状の座屈線（しわ）Ｂに対して直交する方向に強度部材３０を配設して構成する。 In the present invention, as shown in FIGS. 2 and 3, the strength is increased from the lateral joint portion 21 of the cab 10 and the vehicle body frame 20 toward the rear center inside along the floor panel (floor surface) 14 of the cab 10. The member (underfloor reinforcement) 30 is arranged and configured. That is, when the impact force F is applied to the front of the vehicle, the impact force (load) F is applied to the floor panel 14 to buckle the portion B (only shown in FIG. 3, omitted in FIG. 2 to avoid complication). On the other hand, the strength member 30 is arranged in a direction orthogonal to the arc-shaped buckling line (wrinkle) B.

車両の前方に衝撃力Ｆが加わったとき、この衝撃力Ｆは車体フレーム２０を介してキャブマウント２１に伝達される。強度部材３０が無い場合は、キャブマウント２１に伝達された衝撃力Ｆは、客室１３のフロアパネル１４のみで受け止められるために、キャブマウント２１を中心とした円弧状の座屈部Ｂがフロアパネル１４に形成される。 When an impact force F is applied to the front of the vehicle, this impact force F is transmitted to the cab mount 21 via the vehicle body frame 20. In the absence of the strength member 30, the impact force F transmitted to the cab mount 21 is received only by the floor panel 14 of the cabin 13, so that the arc-shaped buckling portion B centered on the cab mount 21 is the floor panel. It is formed at 14.

また、強度部材３０を設けた場合であっても、従来のように車両の前方から後方に向うにつれて、車両の幅方向中央から車体の前後方向と平行に強度部材３０を設けてしまうと、衝撃力Ｆの伝達方向とずれてしまうため、フロアパネル１４に座屈部Ｂが形成されることとなる。 Further, even when the strength member 30 is provided, if the strength member 30 is provided parallel to the front-rear direction of the vehicle body from the center of the width direction of the vehicle as the vehicle moves from the front to the rear as in the conventional case, an impact is generated. Since the force F deviates from the transmission direction, the buckling portion B is formed on the floor panel 14.

これに対して、本発明では、強度部材３０を座屈部Ｂに対して直交するように配設するので、衝撃力Ｆを強度部材３０で十分に受け持つことができ、効率的な荷重伝達経路を得ることができる。したがって、フロアパネル１４が座屈するのを抑制できる。 On the other hand, in the present invention, since the strength member 30 is arranged so as to be orthogonal to the buckling portion B, the impact force F can be sufficiently handled by the strength member 30, and an efficient load transmission path. Can be obtained. Therefore, it is possible to prevent the floor panel 14 from buckling.

なお、強度部材３０は、フロアパネル１４の車体フレーム２０側にスポット溶接等により接続される「コ」の字型の鋼材である。ただし、その形状、材質は容易に変形しない剛性を有していれば特に限定されない。 The strength member 30 is a "U" -shaped steel material connected to the vehicle body frame 20 side of the floor panel 14 by spot welding or the like. However, the shape and material are not particularly limited as long as they have rigidity that does not easily deform.

また、本発明では、横強度部材（レインフォース）１４ｃをフロアパネル１４の幅方向に延在して配設して、強度部材３０をキャブマウント２１と横強度部材１４ｃとを接続して配設されるように構成してもよい。この横強度部材１４ｃは、キャブ１０の重量を支持するための車体幅方向の補強部材であり、その形状、材質は容易に変形しない剛性を有していれば特に限定されない。 Further, in the present invention, the lateral strength member (reinforcement) 14c is arranged so as to extend in the width direction of the floor panel 14, and the strength member 30 is arranged by connecting the cab mount 21 and the lateral strength member 14c. It may be configured to be. The lateral strength member 14c is a reinforcing member in the vehicle body width direction for supporting the weight of the cab 10, and the shape and material thereof are not particularly limited as long as they have rigidity that does not easily deform.

このように構成することで、衝撃力Ｆは、その大部分をキャブマウント２１及び強度部材３０とその後方の横強度部材１４ｃで受け止めることができる。その結果、フロアパネル１４が座屈するのを抑制することができる。 With this configuration, most of the impact force F can be received by the cab mount 21, the strength member 30, and the lateral strength member 14c behind the cab mount 21. As a result, it is possible to prevent the floor panel 14 from buckling.

なお、図２、図３では、フロアパネル１４について、横強度部材１４ｃより前方のフロアパネルをフロントフロア１４ｂ、後方のフロントパネルをリアフロア１４ｄとしている。また、ダッシュパネル１２とフロントフロア１４ｂとの間の区画を１４ａ、客室１３と後方の荷台との間の区画を１４ｅとしている。 In FIGS. 2 and 3, regarding the floor panel 14, the floor panel in front of the lateral strength member 14c is the front floor 14b, and the front panel in the rear is the rear floor 14d. Further, the section between the dash panel 12 and the front floor 14b is 14a, and the section between the cabin 13 and the rear loading platform is 14e.

また、横強度部材１４ｃは、車体フレーム２０側よりフロアパネル１４に接続される部材である。横強度部材１４ｃのＸ方向の一端は、フロントフロア１４ｂの後方端部の上方にリアフロア１４ｄを重ね合わせて接合した部分に対して下方よりスポット溶接等により接合される。横強度部材１４ｃのＸ方向の他端は、一端より前方の位置のフロントフロア１４ｂに対して下方よりスポット溶接等により接合される。 Further, the lateral strength member 14c is a member connected to the floor panel 14 from the vehicle body frame 20 side. One end of the lateral strength member 14c in the X direction is joined by spot welding or the like from below to the portion where the rear floor 14d is overlapped and joined above the rear end portion of the front floor 14b. The other end of the lateral strength member 14c in the X direction is joined to the front floor 14b located in front of one end by spot welding or the like from below.

また、本発明では、図２、図３に示すように、フロアパネル１４の幅方向中央の下方に動力伝達用装置の収納部１５をフロアパネル１４の前後方向に延在して配設するとともに、この収納部１５の上方に位置するフロアパネル１４をその周辺のフロアパネル１４に対して上方に盛り上がるように構成し、横強度部材１４ｃを収納部１５を跨るように配設する。そして、強度部材３０を、キャブマウント２１と、収納部１５と横強度部材１４ｃの交差する部位である交差部２２とを接続して配設する。 Further, in the present invention, as shown in FIGS. 2 and 3, the storage portion 15 of the power transmission device is arranged below the center of the floor panel 14 in the width direction so as to extend in the front-rear direction of the floor panel 14. The floor panel 14 located above the storage portion 15 is configured to bulge upward with respect to the floor panel 14 around the floor panel 14, and the lateral strength member 14c is arranged so as to straddle the storage portion 15. Then, the strength member 30 is arranged by connecting the cab mount 21 and the intersection 22 which is a portion where the storage portion 15 and the lateral strength member 14c intersect.

このように構成することで、エンジンと連結されるトランスミッション等の動力伝達用装置の配設位置を確保しつつ、キャブマウント２１を経由して伝達される衝撃力Ｆを強度部材３０と後方の横強度部材１４ｃとで受けることができる。 With this configuration, the impact force F transmitted via the cab mount 21 is transmitted to the strength member 30 and the rear side while securing the arrangement position of the power transmission device such as the transmission connected to the engine. It can be received with the strength member 14c.

次に、本発明に係る第２実施形態の車両の荷重伝達システムについて、図面を参照しながら説明する。図４に示すように、本発明の第２実施形態は、第１実施形態と同様に、キャブ１０のフロアパネル１４に沿って、キャブ１０と車体フレーム２０の側方の接合部（キャブマウント）２１から後方の中央内側に向って強度部材３０を配設する点は同じであるが、車両の前後方向に延在する第２強度部材（第２アンダーフロアレインフォース）３１を、キャブ１０のフロアパネル１４に沿って、強度部材３０の車両後方端部に接続して配設する点で異なっている。 Next, the vehicle load transmission system of the second embodiment according to the present invention will be described with reference to the drawings. As shown in FIG. 4, in the second embodiment of the present invention, similarly to the first embodiment, the side joint portion (cab mount) between the cab 10 and the vehicle body frame 20 is provided along the floor panel 14 of the cab 10. The point that the strength member 30 is arranged from the 21 toward the center inside of the rear is the same, but the second strength member (second underfloor reinforcement) 31 extending in the front-rear direction of the vehicle is provided on the floor of the cab 10. It differs in that it is arranged along the panel 14 by connecting to the rear end of the vehicle of the strength member 30.

このように構成することで、キャブマウント２１及び強度部材３０により形成される荷重伝達経路に、さらに、第２強度部材３１により形成される新たな荷重伝達経路を接続して、全体としての剛性を更に高めた効率的な荷重伝達経路を形成するので、衝撃力Ｆによるフロアパネル１４の座屈の発生に対する抑制力を更に向上させることができる。 With this configuration, the load transmission path formed by the cab mount 21 and the strength member 30 is further connected to the new load transmission path formed by the second strength member 31, and the overall rigidity is increased. Since a further enhanced and efficient load transmission path is formed, it is possible to further improve the restraining force against the occurrence of buckling of the floor panel 14 due to the impact force F.

なお、図４では、横強度部材１４ｃを介して、フロントフロア１４ｂに配設した強度部材３０に、リアフロア１４ｄに配設した第２強度部材３１を接続しているが、車両の前方衝突時における効率的な荷重伝達経路を得ることができれば、この構成に限定されない。 In FIG. 4, the second strength member 31 arranged on the rear floor 14d is connected to the strength member 30 arranged on the front floor 14b via the lateral strength member 14c, but at the time of a frontal collision of the vehicle. If an efficient load transfer path can be obtained, the present invention is not limited to this configuration.

本発明の車両の荷重伝達システム１によれば、強度部材３０をキャブ１０のフロアパネル（床面）１４に沿って側方の接合部２１から後方の中央内側に向かって配設するので、車体フレーム２０とキャブ１０を別体で構成する車両では、前方で衝突したときにこの衝突時の衝撃力Ｆが車体フレーム２０を介してこの車体フレーム２０とキャブ１０の側方の接合部２１から中央内側に向かってキャブ１０のフロアパネル１４に加わるが、キャブ１０のフロアパネル１４が座屈して変形するのを抑制することができる。 According to the vehicle load transmission system 1 of the present invention, the strength member 30 is arranged along the floor panel (floor surface) 14 of the cab 10 from the side joint 21 toward the rear center inside, so that the vehicle body In a vehicle in which the frame 20 and the cab 10 are formed separately, when the vehicle collides in front, the impact force F at the time of the collision is centered from the lateral joint portion 21 of the vehicle body frame 20 and the cab 10 via the vehicle body frame 20. Although it joins the floor panel 14 of the cab 10 toward the inside, it is possible to prevent the floor panel 14 of the cab 10 from buckling and deforming.
