Description
本発明は、エンジンを防振装置によって車体に取り付ける際にエンジンと防振装置との間に介装される取付けブラケットに関するものである。 The present invention relates to a mounting bracket that is interposed between an engine and a vibration isolator when the engine is attached to a vehicle body by the vibration isolator.
自動車のエンジンは防振装置を介して車体に取り付けられるが、エンジンや防振装置の取付け個所の位置、高さ、向きは一致しているとは限らない。このため、それぞれの取付け個所の形態に応じた二つの取付け部を有する下記特許文献１で示される取付けブラケットを介在させている。したがって、この取付けブラケットは複雑な形状になるが、同時に相応の肉厚を有する強度の高いものである必要がある。 The engine of an automobile is attached to the vehicle body via a vibration isolator, but the position, height, and orientation of the engine and the vibration isolator mounting location are not always the same. For this reason, the attachment bracket shown by following patent document 1 which has two attachment parts according to the form of each attachment location is interposed. Therefore, this mounting bracket has a complicated shape, but at the same time, it must have a high strength with a corresponding thickness.
そこで、従来は、鋳造品、特にアルミ鋳造品を用いていたが、これによる場合はバリ取りを必要とするし、仕上げに機械加工を必要としたりしてコストが高くなるのが欠点である。また、鍛造品もあるが、機械加工を要するのはもちろん、複雑な形状のものを一つ一つ鍛造するにはコストもかかるし、製品形状も限定されてくる。加えて、これら取付けブラケットには相手方部材に取り付ける際に緩衝材としてのゴム層を必要とするが、鋳造品又は鍛造品にこのゴム層を加硫接着するためには、酸化膜層を除去するために機械加工しなければならない（下地処理が要る）。 Therefore, conventionally, cast products, particularly aluminum cast products have been used. However, in this case, deburring is required, and machining is required for finishing, resulting in a high cost. There are also forged products. Needless to say, machining is required, but forging each of the complex shapes one by one is costly and the product shape is limited. In addition, these mounting brackets require a rubber layer as a cushioning material when attached to the mating member. In order to vulcanize and bond this rubber layer to a cast or forged product, the oxide film layer is removed. Must be machined (requires surface preparation).
一方で、下記特許文献２にはこの取付けブラケットをプレス成形してもよいとあるが、どのようなものかは記されておらず、おそらく、鋳造又は鍛造に代えてプレス成形するものと解される。とすると、このような厚肉のものをプレス成形するには、通常のプレス成形機では無理である。
本発明は、上記の課題に対応したもので、通常のプレス機で成形できる程度の肉厚のものを複数枚成形し、これを溶接して一体化することで鋳造品と変わらない強度、形状のものにできるようにしたものである。さらに、取付け部の孔加工や平面度確保のための機械加工も不要にしたものであり、併せてゴム層の加硫接着のために酸化膜層を除去する機械加工も不要にしたものである。 The present invention responds to the above-mentioned problems, and forms a plurality of thick pieces that can be formed by a normal press, and welds and integrates them to have the same strength and shape as a cast product. It can be made into something. In addition, it eliminates the need for drilling the mounting part and machining to ensure flatness, and also eliminates the need for machining to remove the oxide film layer for vulcanization adhesion of the rubber layer. .
以上の課題の下、本発明は、請求項１に記載した、エンジンを防振装置によって車体に取り付ける際にエンジンと防振装置との間に介装される取付ブラケットにおいて、当該取付けブラケットを、鋼板を所定の形状にプレス成形したものを複数枚重ね、合せ部を溶接止めして一体化するとともに、エンジン又は防振装置の取付孔の周囲にゴム層を一体に設けたことを特徴とする取付けブラケットを提供するとともに、これにおいて、請求項２に記載した、鋼板の合せ部の側面がスポット溶接又は連続溶接される手段、請求項３に記載した、強度的に弱い部分において、当板を当てて溶接したり、一つの鋼板に孔をあけて孔の周囲と相手方の鋼板を溶接する補強構造が取られる手段を提供する。 Under the above problems, the present invention provides a mounting bracket that is interposed between the engine and the vibration isolator when the engine is attached to the vehicle body by the vibration isolator described in claim 1. It is characterized in that a plurality of sheets of steel plates pressed into a predetermined shape are stacked, the mating portions are welded together and integrated, and a rubber layer is integrally provided around the mounting hole of the engine or vibration isolator. A mounting bracket is provided, in which means for spot welding or continuous welding of the side surface of the mating portion of the steel plate according to claim 2, and at the weakly strong portion according to claim 3, Provided is a means by which a reinforcing structure is provided for welding by hitting, or by making a hole in one steel plate and welding the periphery of the hole and the opposite steel plate.
請求項１の手段によれば、通常のプレス成形機によるプレス成形と溶接加工とで所要の強度、形状のものができるから、設備を増強する必要がない。また、プレスによって同時に孔加工ができるとともに、精度も高いことから、取付け部や平面度確保のための機械加工を必要としないから、製作コストが安いさらに、ゴム層の加硫接着も鋼板の表面の酸化膜層の除去のための機械加工なしでできるため、この点でもコストの上昇を抑制する。請求項２の手段によれば、求められる強度に応じて溶接の種類を適切なものに選定できるし、請求項３の手段によれば、効率的な補強ができる。 According to the first aspect of the present invention, the required strength and shape can be obtained by press forming and welding with a normal press forming machine, so there is no need to increase the equipment. In addition, since the hole can be drilled simultaneously with the press and the accuracy is high, there is no need for machining to secure the mounting part and flatness, so the manufacturing cost is low, and the rubber layer is vulcanized and bonded to the surface of the steel plate. Since this can be done without machining for removing the oxide film layer, an increase in cost is also suppressed in this respect. According to the means of claim 2, it is possible to select an appropriate type of welding according to the required strength, and according to the means of claim 3, efficient reinforcement can be performed.
以下、本発明の実施の形態を図面を参照して説明する。図１〜４は本発明の第１実施例の取付けブラケットの正面図、側面図、背面図、平面図、図５は斜視図であるが、この取付けブラケットは、側面視でダブルくの字形をした縁付きの板状体であり、それぞれ縁部１、２を突起させた鋼板３、４を背中合せにし、その合せ面の側面を溶接５して一体化したものである。そして、板状部の上方にはエンジンを取り付けるための締結具を挿入する取付孔６が形成され、下方には防振装置に連結する締結具を挿入する取付孔７が形成されている。 Hereinafter, embodiments of the present invention will be described with reference to the drawings. 1 to 4 are a front view, a side view, a rear view, and a plan view of a mounting bracket according to a first embodiment of the present invention, and FIG. 5 is a perspective view. The steel plates 3 and 4 with the edge portions 1 and 2 protruding from each other are back-to-back, and the side surfaces of the mating surfaces are integrated by welding 5. An attachment hole 6 for inserting a fastener for attaching the engine is formed above the plate-like portion, and an attachment hole 7 for inserting a fastener connected to the vibration isolator is formed below.
また、これら取付孔６、７の一方又は両方の周囲は緩衝材としてのゴム層１１を加硫接着するが、これを本例では取付孔６の存する部分の鋼板３、４にゴム層１１を帽子状に被せる状態で加硫接着している（この態様に限定されるものではない）。なお、ゴム層１１の加硫接着は溶接５後に行うことになる。この他、ゴム層１１を一体に設けるには、ゴムを射出成形して接着なしで行うこともある。 In addition, a rubber layer 11 as a cushioning material is vulcanized and bonded around one or both of the mounting holes 6 and 7, and in this example, the rubber layer 11 is attached to the steel plates 3 and 4 where the mounting holes 6 exist. It is vulcanized and adhered in a cap-like state (not limited to this embodiment). The rubber layer 11 is vulcanized and bonded after the welding 5. In addition, in order to provide the rubber layer 11 integrally, rubber may be injection-molded without bonding.
これにおいて、鋼板３、４は厚さ６ｍｍの鋼板を二枚合せにしているが、これに限定されるものではない（三枚以上重ねてもよい）。また、溶接５は合せ部の側面をスポット溶接によっているが、スポット溶接は溶接材を節約できて作業も簡単であるから、これで強度面が確保されるなら、スポット溶接は第一義的に採用される。ただし、より強度が要求されるときには、連続溶接や隅部に溶接ポケットを形成した隅肉連続溶接によることもある。 In this case, the steel plates 3 and 4 are formed by combining two steel plates having a thickness of 6 mm, but the invention is not limited to this (three or more plates may be stacked). In addition, although the welding 5 uses spot welding on the side surface of the mating portion, spot welding can save welding materials and is easy to work. Adopted. However, when higher strength is required, continuous welding or fillet continuous welding with a weld pocket formed at the corner may be used.
加えて、本発明では、強度的に弱い部分は当該個所を補強する補強構造がとられる。第１実施例における具体例として、くの字の折曲部の間の一方の鋼板４に孔８をあけ、この孔８の周囲と相手方の鋼板３とを（スポット）溶接５している。すなわち、二つの鋼板３、４を一体化する溶接を接触面（合せ面）にも設けることで、一体化をより強化して強度を高めるようにしているのである。 In addition, in the present invention, a reinforcing structure is provided to reinforce the portion where the strength is weak. As a specific example in the first embodiment, a hole 8 is formed in one steel plate 4 between the bent portions of the dogleg shape, and the periphery of the hole 8 and the counterpart steel plate 3 are (spot) welded 5. That is, by providing welding for integrating the two steel plates 3 and 4 also on the contact surface (matching surface), the integration is further strengthened to increase the strength.
図６〜図８は第２実施例の取付けブラケットの正面図、側面図、背面図、図９は斜視図であるが、本例のものも、形状、構造及び溶接の態様は第１実施例のものと同じであるが、補強構造として、一方の鋼板４の上部に取付孔６の周囲を欠落させた当板９をあてがい、その縁を鋼板４に対して（スポット）溶接５したものである。また、他方の鋼板３の折曲部において孔１０をあけ、この孔１０の周囲と相手方の鋼板４に（スポット）溶接５をしている。 6 to 8 are a front view, a side view, and a rear view of the mounting bracket of the second embodiment, and FIG. 9 is a perspective view, but the shape, structure, and welding mode of the present embodiment are also the first embodiment. As a reinforcing structure, a contact plate 9 with the periphery of the mounting hole 6 missing is applied to the upper part of one steel plate 4 and the edge thereof is (spot) welded 5 to the steel plate 4 is there. Further, a hole 10 is made in the bent portion of the other steel plate 3, and (spot) welding 5 is performed around the hole 10 and the other steel plate 4.
以上、本発明は、通常のプレス成形機で成形できる範囲の鋼板を用いるプレス成形と溶接加工とで必要な形状、構造、強度を確保したものであり、設備の増強が必要ないから、コストの上昇を抑えられる。また、プレスによって同時に孔加工ができるとともに、精度も高いことから、取付け部や平面度確保のための機械加工を必要としないし、ゴム層の加硫接着も鋼板の表面の酸化膜層の除去のための機械加工なしでできるため、この点でもコストの上昇を抑制する。 As described above, the present invention secures the necessary shape, structure, and strength by press forming and welding using a steel plate in a range that can be formed by a normal press forming machine, and does not require equipment enhancement. The rise can be suppressed. In addition, since the hole can be drilled simultaneously with the press and the accuracy is high, there is no need for machining to secure the mounting part and flatness, and the vulcanization adhesion of the rubber layer also removes the oxide film layer on the surface of the steel plate. Because this can be done without machining, the increase in cost is also suppressed in this respect.
さらに、鋳造や鍛造を排することができるから、統合的にコスト低減が可能になる。発明者等の試算では、第１及び第２実施例のもので約６０％程度のコストで製作できることが判明した。加えて、強度的に弱い部分のみを補強構造によって集中的に補強できるようにしたものであるから、効率的な補強ができる。 Furthermore, since casting and forging can be eliminated, cost can be reduced in an integrated manner. According to the inventors' estimation, it was found that the first and second embodiments can be manufactured at a cost of about 60%. In addition, since only the weakly strong portions can be intensively reinforced by the reinforcing structure, efficient reinforcement can be performed.
