Description

【０００１】
【産業上の利用分野】
この発明は、自動車用補機部品の取付構造に関するものである。
【０００２】
【従来の技術及びその課題】
従来、例えば図２に示すような自動車用補機部品であるパワーステアリングポンプの取付構造において、エンジン１には固設状にパワーステアリングポンプブラケット２が設けられ、このパワーステアリングポンプブラケット２には外側支持片部３と内側支持片部４が突出形成されており、この一対の支持片部３，４間にパワーステアリングポンプ５の取付部６を嵌め込んで、取付部６に形成されている通し孔６ａ内に外側支持片部３の外側より通しボルト８を挿通させて、通しボルト８の先端側にブッシュ９を介在させてナット１０を締め付けて、パワーステアリングポンプブラケット２にパワーステアリングポンプ５が取り付けられるものであるが、パワーステアリングポンプ５にはエンジン１側からの動力がベルトを介し伝達されるプーリー７が設けられており、このプーリー７にＡで示すベルト張力を掛けた状態で前記通しボルト８にナット１０を締め付けて固定しており、この際、ベルト張力Ａが加わることによりパワーステアリングポンプ５は図２に示すように傾斜状態となり、前記外側支持片部３の内側面に傾いた状態でパワーステアリングポンプ５の取付部６が点状に当接し片当り部Ｐが発生してしまい、この片当り部Ｐには図中Ｂで示す矢印方向に力が加わり、外側支持片部３を外側へ開けようとする力が掛かることとなり、従って、パワーステアリングポンプブラケット２にはこのＢで示す力に対抗させるために相当の強度を持たせる必要があり、そのためパワーステアリングポンプブラケット２を肉厚状に形成させておく必要があり、パワーステアリングポンプブラケット２の重量が増大してしまうという問題点があった。
【０００３】
【課題を解決するための手段】
本発明は上記従来の問題点に鑑み案出したものであって、自動車用補機部品を取り付けるブラケットを軽量かつ安価なものとすることのできる取付構造を提供せんことを目的とし、その第１の要旨は、一端側にベルト張力が掛かるプーリーを有する補機部品の取付部を、ブラケットに形成された第１支持片部と第２支持片部の間に嵌め込んでボルトで締結する取付構造において、該ボルトを挿通する前記第１支持片部の第１取付穴の軸線と、前記第２支持片部の第２取付穴の軸線が、ベルト張力により補機が傾斜する方向と逆方向にオフセットするよう該第１取付穴と該第２取付穴を形成し、前記オフセット寸法は、前記補機部品の取付部と、前記第１支持片部または前記第２支持片部の接触面が面接触となる寸法であることである。
また、第２の要旨は、前記第１取付穴の軸線と前記第２取付穴の軸線がそれぞれ前記プーリーの軸線と平行になるように配置されたことである。
【０００４】
【実施例】
以下、本発明の実施例を図面に基づいて説明する。
図１は、パワーステアリングポンプの取付構造を示す要部拡大構成図であり、エンジン１にはパワーステアリングポンプブラケット２が固設されており、このパワーステアリングポンプブラケット２には下方に突出状に平行に外側支持片部３と内側支持片部４が形成されており、この一対の支持片部３，４間に、下側からパワーステアリングポンプ５の取付部６を嵌め込んで、取付部６に形成されている通し孔６ａ内に通しボルト８を挿通させて、通しボルト８の先端にナット１０を締め付け、パワーステアリングポンプブラケット２にパワーステアリングポンプ５を取り付けることができるように構成されており、本例においては、前記外側支持片部３に形成されている通しボルト８を通すための取付穴３ａに対し、内側支持片部４に形成されている取付穴４ａは、図中ｃで示す寸法分だけ上方向にオフセットされて形成され、右側の取付穴３ａから左側の取付穴４ａに向かって上傾するようにオフセット状に各取付穴３ａ，４ａが形成されている。また、取付穴４ａ内にはブッシュ９を嵌合できるように構成されている。
【０００５】
このようなオフセット状の取付穴３ａ，４ａ内に前記通しボルト８を外側支持片部３側から通すと、通しボルト８は水平面に対し傾斜した状態で配設されることとなる。即ち、前記通しボルト８にナット１０を締め付ける前に、パワーステアリングポンプ５から突出されたプーリー７にはエンジン１側からベルトが掛装されて、プーリー７には図中Ａで示す方向にベルト張力が加わることとなるが、このベルト張力Ａが加わった時に、前記外側支持片部３の内側面に対しパワーステアリングポンプ５の取付部６の右端面が面接触状態で当接されるように前記オフセットｃの寸法が設定されている。
【０００６】
即ち、取付部６に水平方向に貫通形成された通し穴６ａの内周面に内側支持片部４側の通しボルト８の外周面が当接するため、ベルト張力Ａが加わった時にもパワーステアリングポンプ５はブラケット２に対し従来例のように傾くことがなく、パワーステアリングポンプ５の取付部６の右端面は良好に外側支持片部３の内側端面に面接触し、従来のように片当り部Ｐが発生することがなく、従って、外側支持片部３には従来のＢで示すような力は加わることがない。そのため、図１のパワーステアリングポンプブラケット２においては従来のようなＢで示す外側に向かう力が加わらないために、外側支持片部３等の肉厚を薄く形成させておいても十分な強度が得られることとなり、従ってパワーステアリングポンプブラケット２の全体の強度を従来よりも低減させて肉厚を薄くして全体を軽量化させることができ、コストを低減させることができるものとなる。
【０００７】
なお、本例では、自動車用補機部品の代表例としてのパワーステアリングポンプの取付構造を例示したが、パワーステアリングポンプ以外の他の自動車用補機部品であるオルタネーター，コンプレッサー，エアポンプ等の取付構造においても同様な構造を採用して、ブラケットを軽量化させることができるものとなる。
また、本例では、通しボルト８にナット１０を締め付ける構造を例示したが、ナットを用いることなく前後２本のボルト８，８で締め付ける構造の場合にも、同様に取付穴３ａ，４ａをオフセットさせておけば自動車用補機の傾きを防ぐことができる。
【０００８】
【発明の効果】
本発明は、一端側にベルト張力が掛かるプーリーを有する補機部品の取付部を、ブラケットに形成された第１支持片部と第２支持片部の間に嵌め込んでボルトで締結する取付構造において、該ボルトを挿通する前記第１支持片部の第１取付穴の軸線と、前記第２支持片部の第２取付穴の軸線が、ベルト張力により補機が傾斜する方向と逆方向にオフセットするよう該第１取付穴と該第２取付穴を形成し、前記オフセット寸法は、前記補機部品の取付部と、前記第１支持片部または前記第２支持片部の接触面が面接触となる寸法であることにより、補機部品のプーリーにベルト張力が掛かった状態では補機部品の取付部がブ ラケットに面接触となり、従来のようにブラケットに補機部品が片当りすることがなく、ブラケットには異常な力が加わらないために、ブラケットの肉厚を薄く形成させてブラケットを軽量化させることができ、ブラケットのコストを低減させてかつ取付強度を大とし得る効果を有する。

Although attached, the power steering pump 5 is a pump through which power from the engine 1 is transmitted via a belt. A pulley 7 is provided, and a nut 10 is fastened and fixed to the through bolt 8 in a state where a belt tension indicated by A is applied to the pulley 7. At this time, the belt tension A is applied to the power steering pump. 2 is in an inclined state as shown in FIG. 2, and the mounting portion 6 of the power steering pump 5 abuts in a point-like manner in a state inclined to the inner surface of the outer support piece portion 3, and a piece contact portion P is generated. A force is applied to the piece contact portion P in the direction of the arrow indicated by B in the drawing, and a force is applied to open the outer support piece portion 3 outward. Therefore, the power steering pump bracket 2 is indicated by B. In order to counteract the force, it is necessary to have a considerable strength. For this reason, the power steering pump bracket 2 must be formed thick, and the power steering pump Weight of up bracket 2 has a problem that increases.
[0003]
[Means for Solving the Problems]
The present invention has been devised in view of the above-mentioned conventional problems, and an object of the present invention is to provide a mounting structure that can make a bracket for mounting an auxiliary component for an automobile lightweight and inexpensive. The gist of this is an attachment structure in which an attachment part of an auxiliary machine part having a pulley to which belt tension is applied at one end side is fitted between a first support piece part and a second support piece part formed on a bracket and fastened with a bolt. The axis of the first mounting hole of the first support piece portion through which the bolt is inserted and the axis of the second mounting hole of the second support piece portion are in a direction opposite to the direction in which the accessory is inclined by belt tension. The first mounting hole and the second mounting hole are formed so as to be offset, and the offset dimension is determined by a mounting surface of the accessory part and a contact surface of the first support piece portion or the second support piece portion. It is a dimension which becomes contact .
The second gist is that the axis of the first mounting hole and the axis of the second mounting hole are arranged so as to be parallel to the axis of the pulley.
[0004]
【Example】
Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 is an enlarged configuration diagram of a main part showing a mounting structure of a power steering pump. A power steering pump bracket 2 is fixed to the engine 1 and is parallel to the power steering pump bracket 2 so as to protrude downward. An outer support piece portion 3 and an inner support piece portion 4 are formed on the inner portion of the power steering pump 5. The attachment portion 6 of the power steering pump 5 is fitted between the pair of support piece portions 3 and 4 from the lower side. The through bolt 8 is inserted into the formed through hole 6a, the nut 10 is fastened to the tip of the through bolt 8, and the power steering pump 5 can be attached to the power steering pump bracket 2. In this example, it forms in the inner side support piece part 4 with respect to the attachment hole 3a for letting the through bolt 8 formed in the said outer side support piece part 3 pass. The mounting holes 4a are offset in the upward direction by the dimension indicated by c in the figure, and each mounting hole is offset so as to incline upward from the right mounting hole 3a toward the left mounting hole 4a. 3a and 4a are formed. Further, the bush 9 can be fitted into the mounting hole 4a.
[0005]
When the through-bolt 8 is passed through the offset mounting holes 3a, 4a from the outer support piece 3 side, the through-bolt 8 is disposed in an inclined state with respect to the horizontal plane. That is, before tightening the nut 10 to the through-bolt 8, a belt is hung from the engine 1 side on the pulley 7 protruding from the power steering pump 5, and the belt tension is applied to the pulley 7 in the direction indicated by A in the figure. However, when the belt tension A is applied, the right end surface of the mounting portion 6 of the power steering pump 5 is brought into contact with the inner surface of the outer support piece 3 in a surface contact state. The dimension of the offset c is set.
[0006]
That is, since the outer peripheral surface of the through bolt 8 on the inner support piece 4 side abuts on the inner peripheral surface of the through hole 6a formed in the mounting portion 6 so as to penetrate in the horizontal direction, the power steering pump is applied even when the belt tension A is applied. 5 is not inclined with respect to the bracket 2 as in the conventional example, and the right end surface of the mounting portion 6 of the power steering pump 5 is in good surface contact with the inner end surface of the outer support piece portion 3, and the one-contact portion as in the conventional case. P does not occur. Therefore, the force as shown by B in the related art is not applied to the outer support piece 3. Therefore, in the power steering pump bracket 2 of FIG. 1, since the outward force indicated by B as in the prior art is not applied, a sufficient strength can be obtained even if the outer support piece 3 or the like is formed thin. Accordingly, the overall strength of the power steering pump bracket 2 can be reduced as compared with the conventional case, the thickness can be reduced and the overall weight can be reduced, and the cost can be reduced.
[0007]
In this example, the power steering pump mounting structure as a typical example of the automotive auxiliary parts is illustrated, but the mounting structure of an alternator, compressor, air pump, etc., which are other automotive auxiliary parts other than the power steering pump. A similar structure can be adopted to reduce the weight of the bracket.
Further, in this example, the structure in which the nut 10 is fastened to the through bolt 8 is illustrated, but the mounting holes 3a and 4a are similarly offset in the structure in which the nuts are fastened by the two bolts 8 and 8 without using the nut. If this is done, the inclination of the auxiliary equipment for automobiles can be prevented.
[0008]
【The invention's effect】
The present invention relates to an attachment structure in which an attachment part of an accessory part having a pulley on which belt tension is applied to one end side is fitted between a first support piece part and a second support piece part formed on a bracket and fastened with a bolt. The axis of the first mounting hole of the first support piece portion through which the bolt is inserted and the axis of the second mounting hole of the second support piece portion are in a direction opposite to the direction in which the accessory is inclined by belt tension. The first mounting hole and the second mounting hole are formed so as to be offset, and the offset dimension is determined by a mounting surface of the accessory part and a contact surface of the first support piece portion or the second support piece portion. by a size as the contact mounting portion of Hoki parts in a state in which took pulley belt tension of the auxiliary component becomes bracket in face contact, the bracket that Hoki parts are per piece in as in the prior art There is no abnormal force applied to the bracket. For no, the thickness of the bracket to the thin bracket can be lighter, it has the effect capable of large a and mounting strength by reducing the cost of the bracket.
