Description

本発明は、トレーラー用メインビームに関し、詳細にはメインビーム構造を有するように、上、下の長さ方向に備えられる上、下フランジの断面上の垂直方向中心線上に備えられるウェブが平面視のとき、凹凸形状に連続することを特徴とする、トレーラー用メインビームに関するものである。
なお、本発明は２０１５年０４月０６日付で先出願された特許文献１に対する韓国国内優先権主張出願である。 The present invention relates to a main beam for a trailer, and more particularly, a web provided on a vertical center line on a cross section of a lower flange is provided in a plan view so as to have a main beam structure. At this time, the present invention relates to a main beam for a trailer characterized by being continuous in an uneven shape.
The present invention is a Korean domestic priority claim application for Patent Document 1 filed earlier on April 06, 2015.

一般的に、トレーラーのメインビーム(MB)については様々のことが知られている。
例えば、図１に示したように、トレーラー用メインフレーム(MF)に備えられるメインビーム(MB)がその代表的なもので、その内容は次の通りである。 In general, various things are known about the main beam (MB) of a trailer.
For example, as shown in FIG. 1, a main beam (MB) provided in a trailer main frame (MF) is a typical one, and the contents thereof are as follows.

図面を参照すれば、従来のトレーラー用メインフレーム(MF)は、メインビーム(MB)とクロスメンバー(CM)とサイドメンバー(SM)とフロアー(図示されず)と、からなる。   Referring to the drawings, a conventional trailer main frame (MF) includes a main beam (MB), a cross member (CM), a side member (SM), and a floor (not shown).

メインビーム(MB)は長さ方向に並んで離れて配置され、その断面が公知の「H」ビームの形状に形成されるように、上、下側に上、下フランジ(TF)(BF)が配置され、この上、下フランジ(TF)(BF)の断面上の中間部分にウェブ(WB)の断面上の上、下端が溶接装着される構造である。   The main beam (MB) is arranged side by side in the longitudinal direction and the upper and lower flanges (TF) (BF) are arranged on the upper and lower sides so that the cross section is formed in the shape of the known `` H '' beam Further, the upper and lower ends on the cross section of the web (WB) are welded to the intermediate portion on the cross section of the lower flange (TF) (BF).

このようなメインビーム(MB)のウェブ(WB)の上側には、長さ方向に等間隔で多数の貫通孔(HL)が形成されて後述するクロスメンバー(CM)が貫通、配置されて装着が容易となるようにした。   On the upper side of the web (WB) of such a main beam (MB), a large number of through holes (HL) are formed at equal intervals in the length direction, and a cross member (CM) described later is penetrated, arranged and mounted. To make it easier.

一方、クロスメンバー(CM)は、前記したウェブ(WB)を貫通しやすいように、同じ形状に形成された貫通孔(HL)を貫通した後、溶接されて一つの組合わせられたフレーム構造を有する。   On the other hand, the cross member (CM) penetrates the through hole (HL) formed in the same shape so as to easily penetrate the above-described web (WB), and is then welded to form one combined frame structure. Have.

このように、一次的に組合わせられたメインビーム(MB)とクロスメンバー(CM)の外側、すなわち、平面視のとき、長方形に形成されるように縁にサイドメンバー(SM)が配置される。   In this way, the side members (SM) are arranged at the edges so as to form a rectangular shape when outside the main beam (MB) and the cross member (CM) that are primarily combined, that is, in plan view. .

長さ方向に長く配置されるサイドメンバー(SM)は、前記したクロスメンバー(CM)の端部に対称形に装着され、幅方向に配置されるサイドメンバー(SM)はメインビーム(MB)の前、後端と前記した長さ方向に配置されたサイドメンバー(SM)の端部と装着されるのである。   Side members (SM) arranged long in the length direction are mounted symmetrically at the end of the cross member (CM) described above, and side members (SM) arranged in the width direction are the main beam (MB). The front and rear ends and the end portions of the side members (SM) arranged in the length direction are attached.

このように装着されたメインフレーム(MF)の前方に牽引車と結合することができるように牽引部(図示されず)を形成してから、後方には道路上で走行しやすいように車軸(図示されず)と車輪(図示されず)を装着すると、トレーラー用メインフレーム(MF)の製作が完了する。   After forming the traction part (not shown) so that it can be coupled with the towing vehicle in front of the main frame (MF) mounted in this way, the axle ( When a wheel (not shown) and a wheel (not shown) are attached, the production of the trailer main frame (MF) is completed.

しかし、一側に詳細に示したように、従来メインビーム(MB)の上、下フランジ(TF)(BF)の間に備えられるウェブ(WB)は、その強度を維持するために、比較的厚い厚さの鉄板を利用するため、トレーラー(PT)の重量が過多となり、相対的に積載重量が少なくなる問題があった。   However, as shown in detail on one side, the web (WB) conventionally provided between the upper and lower flanges (TF) (BF) of the main beam (MB) is relatively free to maintain its strength. Since a thick steel plate is used, the weight of the trailer (PT) is excessive, and there is a problem that the load weight is relatively reduced.

また、前記したメインビーム(MB)の強度を全く補強することができず、トレーラーの自重だけが重くなるので、使用者に信頼を与えることができない問題があった。   In addition, the strength of the main beam (MB) cannot be reinforced at all, and only the weight of the trailer becomes heavy, so there is a problem that the user cannot be trusted.

また、上、下フランジ中心の垂直方向に備えられるウェブが平板形式になっており、メインビームが座屈荷重に脆弱である問題があった。   Further, the web provided in the vertical direction at the center of the upper and lower flanges has a flat plate type, and there is a problem that the main beam is vulnerable to a buckling load.

韓国実用新案登録出願第０００２１４８号Korean utility model registration application No. 0002148

本発明は前述したような問題を解決するために案出されたもので、その目的は、メインビームの上、下フランジ間に備えられるウェブの強度は維持しながらも従来に比べて薄い鉄板を利用したウェブを適用して、車体の重量は減少させるものの、相対的に積載重量は最大限増やすようにすることによって使用者の信頼を高めることにある。   The present invention has been devised in order to solve the above-described problems. The purpose of the present invention is to reduce the thickness of the web provided between the upper and lower flanges of the main beam while reducing the thickness of the steel plate. Although the weight of the vehicle body is reduced by applying the used web, it is to increase the reliability of the user by relatively increasing the load weight as much as possible.

また、上、下フランジ中心の垂直方向に備えられるウェブを比較的薄い厚さの金属板を使用しながらも座屈荷重に対応できるメインビーム用ウェブを広く提供することにある。   Another object of the present invention is to widely provide a main beam web that can cope with a buckling load while using a metal plate having a relatively thin thickness as a web provided in the vertical direction at the center of the upper and lower flanges.

このような目的でなされた本発明は、長さ方向に並んで離れて配置され、上、下の長さ方向に対称形で備えられた上、下フランジと、前記上、下フランジの断面上の垂直方向中心線上にウェブが備えられるメインビームと、前記メインビームを貫通して前方から後方まで等間隔で複数配置されたクロスメンバーと、前記クロスメンバーの両端と前記メインビームの前、後方に配置され、平面視のとき、長方形をなすサイドメンバーからなるトレーラー用メインフレームに関するもので、   The present invention made for such a purpose is arranged in the longitudinal direction apart from each other and provided symmetrically in the upper and lower length directions, and on the cross section of the upper and lower flanges. A main beam having a web on a vertical center line thereof, a plurality of cross members arranged at equal intervals from the front to the rear through the main beam, both ends of the cross member and front and rear of the main beam It is related to the mainframe for trailers consisting of rectangular side members when viewed in plan.

前記メインビームのウェブは、長さ方向平面上に凹凸部が連続的に繰返し形成されることを特徴とする。   The web of the main beam is characterized in that uneven portions are continuously and repeatedly formed on a longitudinal plane.

また、前記凹凸部は、平面上の一側の水平方向に備えられる凹部と、前記凹部の入れ違い方向に対向する凸部からなり；前記凹部と凸部を一体に連結する傾斜部からなる。   Moreover, the said uneven | corrugated | grooved part consists of the recessed part with which the horizontal direction of one side on a plane is provided, and the convex part which opposes the insertion direction of the said recessed part; It consists of the inclined part which connects the said recessed part and a convex part integrally.

また、前記傾斜部の折り曲げ角度は、前記凹部または凸部のいずれかの水平上で４５゜以上９０゜以下の角度で対称形で連続することを特徴とする。   Further, the bending angle of the inclined portion is characterized by being symmetrically continuous at an angle of 45 ° or more and 90 ° or less on the horizontal of either the concave portion or the convex portion.

また、前記ウェブは、厚さ１.６mm以上６.４mm以下の金属板で構成される。   The web is formed of a metal plate having a thickness of 1.6 mm or more and 6.4 mm or less.

メインビームの上、下フランジ間に備えられるウェブの強度は維持しながらも従来に比べて薄い鉄板を利用したウェブを適用して、車体の重量は減少させるものの、相対的に積載重量は最大限増やすようにすることによって、使用者の信頼を高める効果がある。   Although the strength of the web provided between the upper and lower flanges of the main beam is maintained, the weight of the vehicle body is reduced by applying a web using a thin steel plate compared to the conventional one, but the load weight is relatively maximum By increasing the number, there is an effect of increasing the trust of the user.

また、上、下フランジ中心の垂直方向に備えられるウェブを比較的薄い厚さの金属板を使用しながらも座屈荷重に対応できるメインビーム用ウェブを広く提供する効果がある。   Further, there is an effect of widely providing a main beam web that can cope with a buckling load while using a metal plate having a relatively thin thickness as a web provided in the vertical direction at the center of the upper and lower flanges.

図２に示したように、本発明に係るトレーラー用メインビーム１０は、上、下の長さ方向に備えられた上、下フランジ１００、２００と、前記上、下フランジ１００、２００の断面上の垂直方向中心線上に備えられるウェブ(Web)３００を含む。なお、以下、前記したメインビーム１０と組合わせられてトレーラーのメインフレームをなすクロスメンバーとサイドメンバーの構成は従来と同じであるので、別途の説明は省略し、メインビーム１０の構成に対してのみ説明し、符号だけを異にして説明する。   As shown in FIG. 2, the trailer main beam 10 according to the present invention includes upper and lower flanges 100 and 200 provided in the upper and lower length directions, and cross sections of the upper and lower flanges 100 and 200. The web 300 is provided on the vertical center line. In the following description, the structure of the cross member and the side member that are combined with the main beam 10 to form the main frame of the trailer is the same as that of the conventional structure. Only the explanation will be given, and only the reference numerals will be different.

一般的にＨ形鋼やＩ形鋼の場合、上、下対称形で備えられる構成をフランジ(Flange)と称し、このフランジの直角方向に備えられる構成をウェブ(Web)と称するので、本発明においてもその名称に従うことにする。   In general, in the case of H-shaped steel and I-shaped steel, the configuration provided in the upper and lower symmetrical forms is referred to as a flange, and the configuration provided in a direction perpendicular to the flange is referred to as a web. Will follow the name.

ウェブ３００は、長さ方向平面上に凹凸部３１０が連続的に繰返し形成されるコルゲーションパネル(Corrugation Panel)の形状に形成される。   The web 300 is formed in the shape of a corrugation panel in which the concavo-convex portions 310 are continuously and repeatedly formed on the plane in the length direction.

凹凸部３１０は、凹部３１１と凸部３１３と傾斜部３１５とからなる。   The concavo-convex portion 310 includes a concave portion 311, a convex portion 313, and an inclined portion 315.

凹部３１１と凸部３１３は相互入れ違い方向に対応するように形成されるもので、説明の便宜上区分したものである。   The concave portion 311 and the convex portion 313 are formed so as to correspond to the mutual insertion directions, and are divided for convenience of explanation.

傾斜部３１５は、前記した凹部３１１と凸部３１３の各端部を一体に連結する役割をすることによって、本発明に係るウェブ３００は前記した凹部３１１と凸部３１３が傾斜部３１５により連続的に繰返し形成される。   The inclined portion 315 serves to integrally connect the end portions of the concave portion 311 and the convex portion 313, so that the web 300 according to the present invention has the concave portion 311 and the convex portion 313 continuously formed by the inclined portion 315. Repeatedly formed.

一方、傾斜部３１５の折り曲げ角度(θ)は、示したように、凹部３１１または凸部の水平面を基準として、４５゜以上９０゜以下の角度で形成することが好ましく、ウェブ３００を構成する金属板の厚さも更にはトレーラーの種類、例えば、コンテナ運搬用トレーラーの場合、２０フィート用または４０フィートコンテナを運ぶトレーラーの種類によって１.６mm以上６.４mm以下に形成することが好ましい。   On the other hand, the bending angle (θ) of the inclined portion 315 is preferably formed at an angle of 45 ° or more and 90 ° or less with reference to the horizontal surface of the concave portion 311 or the convex portion, as shown in FIG. The thickness of the plate is preferably formed to be not less than 1.6 mm and not more than 6.4 mm depending on the type of trailer, for example, in the case of a container transport trailer, depending on the type of trailer for 20 feet or 40 feet.

その理由としては、比較的薄い厚さの金属板を使用しながらもメインビーム１０をなすウェブ３００が座屈荷重に対して耐久性を維持するとともに車体の重量を大幅に減少させることによって、積載重量を高めるようにするためである。   The reason for this is that the web 300 forming the main beam 10 maintains durability against buckling load while using a relatively thin metal plate, and significantly reduces the weight of the vehicle body. This is to increase the weight.

図３と図４を参照して本発明に係るウェブ３００の製造方法に対して説明する。   A method of manufacturing the web 300 according to the present invention will be described with reference to FIGS.

まず、図３の（ａ）に示したように、直六面体状の金属板を具備し、（ｂ）に示したように、一端と他端とをノッチング(Notching)して後述するメインフレーム１をなすための他の構成の装着を容易にする。   First, as shown in FIG. 3A, a rectangular parallelepiped metal plate is provided, and as shown in FIG. 3B, one end and the other end are notched, and a main frame 1 described later. It is easy to mount other components for achieving the above.

その次に、図４の（ｃ）に示したように、プレス金型を利用して等間隔で貫通孔３２０を形成(ピアシング：Piercing)してクロスメンバー２０の貫通が容易となるようにした後、（ｄ）に図示した折り曲げ工程によって凹凸部３１０を形成する。   Next, as shown in FIG. 4C, through-holes 320 are formed at equal intervals using a press die so that the cross member 20 can be easily penetrated. Thereafter, the concavo-convex portion 310 is formed by the bending process shown in FIG.

この凹凸部３１０の形成は、図５に示したように、図示していないプレス動作によって、このプレス上、下金型(UM)(BM)の間にウェブ３００が形成される金属板を具備した後、押圧して本発明に係るウェブ３００の凹凸部３１０が形成されるのである。   As shown in FIG. 5, the uneven portion 310 includes a metal plate on which the web 300 is formed between the lower mold (UM) (BM) by a pressing operation (not shown). After that, it is pressed to form the uneven portion 310 of the web 300 according to the present invention.

このように形成されたウェブ３００の上、下方向に、上、下フランジ１００、２００を具備させた後、溶接してトレーラー用メインビーム１０が完成する。   After the upper and lower flanges 100 and 200 are provided in the upper and lower directions of the web 300 formed in this way, the trailer main beam 10 is completed by welding.

その次に、図６に示したように、このメインビーム１０にクロスメンバー２０を装着し、このクロスメンバー２０およびメインビーム１０の前、後の両端にサイドメンバー３０を装着してトレーラー用メインフレーム１が完成する。   Next, as shown in FIG. 6, a cross member 20 is attached to the main beam 10, and side members 30 are attached to both front and rear ends of the cross member 20 and the main beam 10. 1 is completed.

このような、凹凸部３１０を備えたメインビーム１０の実施例を説明しながら平板トレーラー用に限定したが、平板トレーラーの外にグースネックトレーラー(Gooseneck Trailer)、グースネックコンボシャシー(Gooseneck Combo Chassis)などのメインビームに適用しても本発明の目的を達成できることはもちろんである。   While the embodiment of the main beam 10 having the uneven portion 310 is described, the embodiment is limited to the flat plate trailer. Of course, the object of the present invention can be achieved even when applied to the main beam.

前述した通り、本発明に係るメインビーム用ウェブ３００は、コルゲーションパネルの形状に形成される凹凸部３１０によって、従来より厚さの薄い鉄板(１.６〜６.４mm)を使用しても構造的な強度を維持することができるので、車体の重量を大幅に減少させることができる。   As described above, the main beam web 300 according to the present invention is structured even if a steel plate (1.6 to 6.4 mm) thinner than the conventional one is used due to the uneven portion 310 formed in the shape of the corrugation panel. As a result, the weight of the vehicle body can be greatly reduced.

また、節減された車体の重量と比べて積載重量を大幅に増やすことができるので、使用者の信頼を高めることができる。   Further, since the loading weight can be greatly increased as compared with the reduced weight of the vehicle body, the reliability of the user can be increased.

また、上、下フランジ中心の垂直方向に備えられるウェブを比較的薄い厚さの金属板を使用しながらも、コルゲーションの形状に連続的に繰り返された凹凸部によって座屈荷重に対応できるメインビーム用ウェブを広く提供することができる。   In addition, the main beam that can cope with the buckling load by the concave and convex portions continuously repeated in the shape of the corrugation while using a relatively thin metal plate for the web provided in the vertical direction at the center of the upper and lower flanges Web can be widely provided.

本発明は前述した特定の好ましい実施例に限定されず、特許請求の範囲で請求する本発明の要旨を逸脱することなく、当該発明が属する技術分野で通常の知識を有した者であれば誰でも多様な変形実施が可能であることはもちろん、そのような変形実施は本発明の特許請求の範囲の記載範囲内にある。   The present invention is not limited to the specific preferred embodiments described above, and anyone who has ordinary knowledge in the technical field to which the invention belongs without departing from the spirit of the invention claimed in the claims. However, various modifications can be made, and such modifications are within the scope of the claims of the present invention.
