Description

本発明は、主としてトラック用シャシフレームにおいて、必要長さ、必要強度のものを容易且つ安価で製作でき、且つ必要に応じてその長さ、強度等を容易に変更し得る構造に関するものである。   The present invention mainly relates to a structure capable of easily and inexpensively manufacturing a required length and required strength of a truck chassis frame and easily changing the length, strength, and the like as required.

トラックでは、一般に図４、図５に示す如き、２本の並行した所定長さのサイドメンバ２、２’を複数本のクロスメンバ３により連結したはしご形のシャシフレーム１が使用されているが、基本的に長いサイドメンバ２、２’は大型プレス機によって成形する必要があり、大型の金型を含む設備費、製作費、管理費等が膨大なものとなっている。   In a truck, as shown in FIGS. 4 and 5, a ladder-type chassis frame 1 in which two parallel side members 2 and 2 ′ having a predetermined length are connected by a plurality of cross members 3 is used. Basically, the long side members 2 and 2 'need to be formed by a large press, and the equipment cost, production cost, management cost and the like including a large die are enormous.

また、前記シャシフレーム１は、トラックの用途、仕向地等によってそのサイドメンバ２、２’に要求される長さやクロスメンバ３を含めたシャシフレーム１の要求強度等を異にするが、この場合、前記要求性能に大きな差があるときは、長いサイドメンバ自体の長さ、断面高さ、板厚の変更或いはシャシフレームへの補強の実施などにより対応する必要がある。   Further, the chassis frame 1 has different lengths required for the side members 2 and 2 ′ and required strength of the chassis frame 1 including the cross member 3 depending on the use of the truck and the destination. When there is a large difference in the required performance, it is necessary to cope by changing the length of the long side member itself, the cross-sectional height, the plate thickness, or reinforcing the chassis frame.

しかしながら、サイドメンバ１の長さ、断面高さ、の異なるものを準備するためには、新たな金型を準備する必要があり、やはり前記設備費、製作費、管理費等が膨大なものとなり、シャシフレームのコストの大きな上昇に繋がっていた。そのため、要求性能上必要なサイドメンバ１の長さ等について、不本意ながらそれに近いところで妥協することも多かった。   However, in order to prepare the side members 1 having different lengths and cross-sectional heights, it is necessary to prepare a new mold, and the equipment cost, production cost, management cost, etc. are enormous. This led to a significant increase in chassis frame costs. For this reason, the length of the side member 1 required for the required performance is unnecessarily compromised in the vicinity.

また、前部、後部の懸架装置装着部等のシャシフレームの強度を向上するため、補強を施す場合も、例えば後記特開公報の如きコスト増の比較的小さな構造を採用する場合が多い。しかし、これでもサイドメンバの補強材を成形するための金型費は当然必要であり、且つ補強材の加工、組付けの費用を要する。
そこで本発明者は、殊にトラック用のシャシフレームに関する前記問題点への対応を根本的に研究した結果、本発明に至ったものである。
特開２００２−０１２１６４号公報 In addition, in order to improve the strength of the chassis frame such as the front and rear suspension device mounting portions, a structure with a relatively small increase in cost as described in Japanese Patent Laid-Open Publication No. 2000-168, for example, is often employed when reinforcing. However, the mold cost for molding the side member reinforcing material is still necessary, and the processing and assembling costs of the reinforcing material are required.
Therefore, the inventor of the present invention has finally reached the present invention as a result of fundamental researches on the above-mentioned problem relating to the chassis frame for trucks.
JP 2002-012164 A

本発明が解決しようとする問題点は、主としてトラック用シャシフレームにおいて、トラックの用途等に応じて必要長さ、強度のものを容易且つ安価で製作でき、且つ必要に応じてその長さ、強度等を容易且つ安価に変更し得る構造を提供することである。   The problem to be solved by the present invention is that a chassis frame for trucks can be manufactured easily and inexpensively with the required length and strength according to the use of the truck, and the length and strength as required.

The front portion 22 has a U-shaped cross section. The first cross member portions 16 and 16 are integrally formed at the front ends of the first and second small member members 12 and 12, and the second cross member member 17 is connected between the rear ends of the first small side member members 12 and 12, respectively. The adjusting portion 23 is formed by connecting the middle portions of the second small side member members 13 and 13 having a U-shaped cross section parallel to each other by a third cross member member 18, and the suspension portion 24 is a third small side having a U-shaped cross section. The fourth and fifth cross member portions 19, 19 and 20, 20 are integrally formed at the front and rear ends of the member members 14, 14, and the rear portion 25 is formed by a fourth small side member member 15 having a U-shaped cross section. , 15 rear end Because characterized by comprising forming a integrally sixth cross member portion 21, by comprising a small side member member and the cross member or portion, the mold requires a relatively small, thus the equipment cost, Production costs and management costs can be kept low.

このことは、トラック等の用途、仕向地等によって前記サイドメンバの長さやクロスメンバを含めたシャシフレームの要求強度等を変更したい場合に、納期を含めて比較的柔軟に対応することができることである。   This is because it is possible to respond relatively flexibly including the delivery date when it is desired to change the length of the side member and the required strength of the chassis frame including the cross member depending on the use of the truck and the destination. is there.

また、シャシフレームを、小サイドメンバ部材とクロスメンバ部材または部分からなる複数個のユニットにより構成したことにより、例えば後部の懸架装置装着部等のシャシフレームの強度を向上したい場合は、設計当初から当該部を構成するユニットの小サイドメンバ部材とクロスメンバ部材または部分の断面高さを大とし、或いは板厚の厚いものを使用して対応し、補強を不要にすることもできる。   In addition, since the chassis frame is composed of a plurality of units consisting of a small side member member and a cross member member or portion, for example, when it is desired to improve the strength of the chassis frame such as the rear suspension device mounting portion, It is possible to increase the cross-sectional height of the small side member member and the cross member member or the portion of the unit constituting the part, or to use a thick plate member so that reinforcement is not necessary.

さらに、シャシフレームを、小サイドメンバ部材とクロスメンバ部材または部分からなる複数個のユニットにより構成したことにより、ユニット毎に組付けでき、また必要機器の装着ができるとともに、万一シャシフレームが破損したときもユニット毎に修理することもできる。   Furthermore, because the chassis frame is composed of multiple units consisting of small side member members and cross member members or parts, it can be assembled for each unit, and necessary equipment can be mounted and the chassis frame should be damaged.
