Description

【0001】
【発明の属する技術分野】
この発明は、自動2輪車のエンジンの電子制御装置であるECUやバッテリなどの電装品を有利に取付けるための構造に関する。
【0002】
【従来の技術】
従来のECUは、フェアリングを支持するためヘッドパイプから前方へ延出しするセンターカウルステーや、車体フレーム又はシートレール等へ支持されることが多い。特に車体フレームに対する支持の場合は主フレームの外側へ取付けられることが多く、また、シートレールに対しては、リヤフェンダを介して支持されることもある。
【0003】
このような一例として、特開昭63−82886号には、C字状断面をなす左右一対の主フレームを、互いの開口部が対向するように配置し、この開口部にエンジン用等の電装品を取付けた自動2輪車が示されている。なお、この例では、側面視において、主フレームと重ならない形式のエンジンを採用し、かつ電装品も全く外観されないように配設されている。
【0004】
【発明が解決しようとする課題】
ECUなどの高価な電装品は、できるだけ車体で保護する配置が望ましく、また、ECUやバッテリなどの比較的重量がある電装品はマスの集中を図れることができかつワイヤーハーネスを可能な限り短縮できる配置が望まれている。
【0005】
さらに、ECUなどは発熱するのでこれを効率的に冷却することが必要であり、またカプラー部における結線作業を容易にできることが好ましいが、前記特開昭63−82886号は、主フレームとエンジンが重ならない形式のエンジンを採用しているため、発熱部品に対して冷却する動機が少ない。
【0006】
また、電装品は側面視で主フレームに隠された配置になっているが、これはワイヤーハーネスを電装品のケース自体から直接一体的に延出させ、結線部を車体上の作業容易な別の場所に設けてあるためである。しかしながら、このようにすると、結線作業に際して、電装品と対応する結線部を捜す手間が増え、かつワイヤーハーネスの短縮化に反する。
【0007】
なお、電装品のケース自体から直接一体的に延出するワイヤーハーネスを使用しない場合、電装品のケースにワイヤーハーネスを結線するための結線部を設けなければならなくなるが、このような場合には、電装品側の結線部が主フレームに隠されてしまっているため、結線時の作業性が悪くなる。
【0008】
【課題を解決するための手段】
上記課題を解決するため本願発明の請求項1に係る自動2輪車の電装品取付構造は、フロントフォークを回動自在に支持するヘッドパイプから後方へ左右に対をなして延びる主フレームを有する車体フレームを備えた自動2輪車において、記左右の主フレーム間にエンジンの気筒を側面視で前記主フレームと重なるように配設し、この気筒の後方かつ平面視で前記気筒を含むエンジンと前記主フレームの内側面との間に間隙を設けて走行風の通路を形成し、
この間隙内にエンジン制御用のECUを側面視で前記主フレームと重なるように配設する。
【0009】
さらに、このECUを、そのカプラーが側面視で前記主フレームの下面から外方へ覗くように配設させ、ECUを車体側方から作業可能に配設する。
【0010】
請求項2は上記請求項1において、前記気筒が、側面視で上向きの第1の気筒と下向きの第2の気筒を備え、平面視でこの第2の気筒後方に前記間隙及びECUを配設させるようにしたことを特徴とする。
【0011】
請求項3は、上記請求項1において、前記車体フレームの左右後部間にリヤサスペンション用緩衝器の上端部を取付けるための緩衝器取付部を設け、この緩衝器取付部側面にバッテリを支持させることを特徴とする
【0012】
請求項4は、上記請求項3において、前記緩衝器取付部の左右両側を車体カバーで覆うとともに、この車体カバーの側面にバッテリの覗き窓を設けることを特徴とする
【0013】
【発明の効果】
請求項1によれば、ECUを左右のフレーム間に配設し、側面視で主フレームと重なり、かつEUCのカプラーが主フレームの下面から外部へ覗くように配設したので、剛性部材である主フレームによって高価な電装品であるECUを保護する配置にできるとともに、カプラーに対する作業を車体側方から容易に行うことができ、結線作業が容易迅速化する。
【0014】
また、エンジンの気筒を側面視で左右の主フレーム間に配設し、平面視でこの気筒後方かつ気筒を含むエンジンと主フレームの内側面との間に間隙を設けて走行風の通路を形成し、この間隙内にECUを配設したので、高価なECUを効果的に保護可能な場所に配置できるとともに、左右の主フレーム間において気筒後方に通気通路をなす間隙を形成できるため、この間隙を流れる走行風を利用してECUを効率的に冷却でき、ECUが過度に温度上昇することを防止できる。そのうえ、ECUのカプラーがエンジン近傍に位置するので、ワイヤーハーネスを可能な限り短縮できる。
【0015】
請求項2によれば、さらに、 エンジンの気筒が、側面視で上向きの第1の気筒と下向きの第2の気筒を備え、平面視でこの第2の気筒後方に前記間隙及びECUを配設させたので、ECUの前方に位置する第2の気筒を利用して走行風をECUへ向かって流れやすくしてECUを効率的に冷却することができる。
【0016】
請求項3によれば、また、緩衝器取付部の側面にバッテリを設ければ、重量の大きなバッテリを車体中心部に支持できるので、マスの集中を図ることができ、かつワイヤーハーネスを可能な限り短縮できる。
【0017】
請求項4によれば、そのうえ、車体カバーにバッテリの覗き穴を設ければ、車体カバーを車体へ取付けたままの状態で、バッテリの点検ができるので点検やメンテナンスが容易になる。しかも、車体内部を後方へ流れる走行風がこの覗き窓から外部へ抜けるようになるため、走行風を緩衝器の周囲へ集めることができ、その結果、発熱部品である緩衝器の冷却効率を高める。
【0018】

まず、図2に基づいて本願発明の適用された自動2輪車の全体構造を概略説明する。前輪1を支持するフロントフォーク2の上端はヘッドパイプ3へ回動自在に支持され、ハンドルにて操向されるようになっている。
【0020】
ヘッドパイプ3からは、縦長角筒断面の主フレーム5が二股状に拡開しながら斜め下がりに後方へ左右一対で延び、左右の各主フレーム5の後端部には上下方向へ延びるピボットフレーム6の上部が接続されている。
【0021】
ピボットフレーム6にはピボット7で片持式リヤアーム8の前端部が揺動自在に支持され、その後端部に後輪9が支持されている。
【0022】
左右のピボットフレーム6の上部間を連結して設けられたクロスパイプ10(図4参照)の中間部には緩衝器取付部11が上方へ突出して設けられ、この緩衝器取付部11の頂部12に緩衝器13の上端部が支持されている。
【0023】
緩衝器13の下端部はピボットフレーム6と片持式リヤアーム8間に設けられたクッションリンク14へ連結されている。
【0024】
主フレーム5とピボットフレーム6は車体フレームを構成し、主フレーム5のエンジンハンガ15及び、ピボットフレーム6のマウント部16a,16bにV型エンジン17が支持されている。
【0025】
V型エンジン17は前部に右気筒18と左気筒19が前方へV型に拡開して設けられ、右気筒18は斜め上向きに、左気筒19は斜め下向きに設けられている。
【0026】
V型エンジン17の前方にラジエタ20が、上方には吸気ボックス21が配設されており、吸気ボックス21の上方に燃料タンク22が配設されている。
【0027】
吸気ボックス21は、フェアリング23のヘッドパイプ前方部分へ前向きに開口する吸気ダクト24より走行風を取り入れてV型エンジン17へ吸気するようになっている。
【0028】
フェアリング23は、車体の前部からV型エンジン17の左右を覆い、車体前方からフェアリング23内側へ取り込まれてラジエタ20を冷却した走行風はラジエタ20後方のフェアリング23に設けられた排気口25から外側へ排出される。
【0029】
緩衝器取付部11の頂部12には、斜め上がりに後方へシートレール26が延び、このシートレール26に支持されたシートカウル27上にシート28が取付けられている。
【0030】
図3に明らかなように、V型エンジン17と主フレーム5の間には、間隙30が設けられ、この間隙30中にエンジン制御用の電装品であるECU31が収容され、主フレーム5の内側面に車体内方へ突出して設けられたナット32にボルト33で取付けられている。
【0031】
ECU31が収容されている間隙30は、斜め下向きに前方へ突出している左気筒19上方の空間と連通しており、走行風Wが左気筒19にガイドされて流れ込み易くなる走行風の通路になっている。
【0032】
図1に明らかなように、ECU31と主フレーム5は側面視で重なっており、ECU31の下端部には、ECU31の下部に設けられているカプラー34が主フレーム5の下面から外側方へ覗いている。
【0033】
さらに、主フレーム5のヘッドパイプ3の近傍部外側面でフェアリング23との間にデトネーションカウンターボックス35が取付けられている。このデトネーションカウンターボックス35は、乗車姿勢のライダーの脚から離れた位置でかつ側面視においてフェアリング23に隠されない位置へ配設される。
【0034】
図4に明らかなように、緩衝器取付部11は左右のピボットフレーム6よりも車体中心側へ入り込んでおり、緩衝器取付部11の側面に重量のある電装品であるバッテリ36が支持されている。

【0036】
次に、本実施形態の作用を説明する。電装品であるECU31及びバッテリ36が左右の主フレーム5及びピボットフレーム6の内側に配設されているため、これらの電装品は、剛性部材である車体フレーム(5,6)により保護され、比較的高価な部品であるECU31及びバッテリ36が効果的に保護される。
【0037】
また、ECU31がエンジン17の近傍に位置し、かつバッテリ36も車体中心近傍に位置するから、それぞれワイヤーハーネスを可能な限り短縮できる。しかも、重量のあるバッテリ36が車体中心近くに配設されるため、マスの集中を図ることができる。
【0038】
さらに、ECU31は、前方へ下向きに突出する左気筒19の後方となる間隙30内へ配設されているので、走行風がECU31の周囲へ流れ易くなり、温度上昇を避ける必要があるECU31を効率的に冷却できる。
【0039】
また、ECU31の下部に設けられたカプラー34が主フレーム5の下面から外部へ覗いているので、外側方からの結線作業が容易迅速化する。
【0040】
そのうえ、バッテリ36は緩衝器取付部11側方の空間を配設スペースとして有効利用できるとともに、シートカウル27を取り外すことなく覗き窓37からバッテリ36を点検できるので、点検及びメンテナンス性に優れたものになる。
【0041】
しかも、車体内部の前記間隙30側から後方へ流れてきた走行風Wが緩衝器取付部11の周囲を通って覗き窓37から外側方へ流出するので走行風Wの抜けが良くなり、緩衝器取付部11の周囲に走行風Wを集め易くなるので、発熱し易い緩衝器13を有効に冷却できる。
【0042】
さらにまた、デトネーションカウンターボックス35を乗車姿勢のライダーの脚から離れた位置でかつ側面視においてフェアリング23に隠されない位置へ配設したので、ライダーが乗車したままでデトネーションカウンターボックス35の点検ができ、整備性が良好になる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a structure for advantageously mounting electric components such as an ECU and a battery, which are electronic control units for a motorcycle engine, and the like.
[0002]
[Prior art]
Conventional ECUs are often supported by a center cowl stay extending forward from a head pipe to support a fairing, a vehicle body frame, a seat rail, or the like. In particular, in the case of supporting the vehicle body frame, it is often attached to the outside of the main frame, and the seat rail is sometimes supported via a rear fender.
[0003]
As one example, Japanese Patent Application Laid-Open No. 63-82886 discloses that a pair of left and right main frames having a C-shaped cross section are arranged so that their openings face each other. A motorcycle equipped with a product is shown. In this example, an engine of a type that does not overlap with the main frame is employed in a side view, and the electrical components are arranged so as not to be seen at all.
[0004]
[Problems to be solved by the invention]
It is desirable to arrange expensive electric components such as ECUs with the vehicle body as much as possible, and relatively heavy electric components such as ECUs and batteries can concentrate mass and shorten the wire harness as much as possible. An arrangement is desired.
[0005]
Further, since the ECU and the like generate heat, it is necessary to efficiently cool the heat, and it is preferable that the connection work in the coupler portion can be easily performed. However, Japanese Patent Application Laid-Open No. 63-82886 discloses that the main frame and the engine are Since the engine does not overlap, there is little motivation to cool the heat-generating components.
[0006]
Also, the electrical components are hidden behind the main frame when viewed from the side.This is because the wire harness extends directly directly from the electrical component case itself, and the connection part is easily accessible on the vehicle body. It is because it is provided in the place. However, in this case, in the connection work, the trouble of searching for the connection part corresponding to the electrical component is increased, and it is against the shortening of the wire harness.
[0007]
If a wire harness that extends directly from the case of the electrical component itself is not used, a connection portion for connecting the wire harness to the case of the electrical component must be provided. Since the connection part on the electrical component side is hidden by the main frame, workability at the time of connection is deteriorated.
[0008]
[Means for Solving the Problems]
In order to solve the above-mentioned problem, an electric component mounting structure for a motorcycle according to claim 1 of the present invention has a main frame extending in a pair to the left and right from a head pipe rotatably supporting a front fork. engine including at motorcycle having a body frame, the cylinder of the engine between the main frame before Symbol lateral disposed so as to overlap with the main frame in a side view, the cylinder behind and plan view of the cylinder And providing a gap between the inner surface of the main frame and a passage of the traveling wind,
An ECU for controlling the engine is disposed in the gap so as to overlap the main frame in a side view.
[0009]
Further, the ECU, the coupler is disposed so as seen through the lower surface of the main frame as viewed from the side outward, it arranged to allow the working of ECU from the vehicle body side.
[0010]
According to a second aspect, in the first aspect, the cylinder includes a first cylinder facing upward in a side view and a second cylinder facing downward, and the gap and the ECU are disposed behind the second cylinder in a plan view. It is characterized in that it is made to be.
[0011]
According to a third aspect of the present invention , in the first aspect, a shock absorber mounting portion for mounting an upper end of a rear suspension shock absorber is provided between left and right rear portions of the vehicle body frame, and a battery is supported on a side surface of the shock absorber mounting portion. It is characterized by .
[0012]
A fourth aspect of the present invention is characterized in that , in the third aspect, both right and left sides of the shock absorber mounting portion are covered with a vehicle body cover, and a viewing window for a battery is provided on a side surface of the vehicle body cover.
[0013]
【The invention's effect】
According to claim 1, and disposed between the main frame of the right and left ECU, it overlaps the main frame as viewed from the side, and therefore is disposed so as couplers EUC peek outside from the lower surface of the main frame, a rigid member A certain main frame can be arranged to protect the ECU, which is an expensive electrical component, and the work on the coupler can be easily performed from the side of the vehicle body, thereby facilitating the connection work.
[0014]
In addition, a cylinder of the engine is disposed between the left and right main frames in a side view, and a gap is provided between the engine including the cylinder and the inner surface of the main frame behind the cylinder in a plan view to form a passage for traveling wind. and, since the disposed ECU in this gap, it is possible to place an expensive ECU to effectively protect possible locations, can form a gap constituting a ventilation passage into the cylinder rear between the left and right main frames because, during this time The ECU can be efficiently cooled by using the traveling wind flowing through the gap, and the temperature of the ECU can be prevented from rising excessively. In addition, since the ECU coupler is located near the engine, the wire harness can be shortened as much as possible.
[0015]
According to the second aspect, the cylinder of the engine further includes a first cylinder facing upward in a side view and a second cylinder facing downward, and the gap and the ECU are disposed behind the second cylinder in a plan view. As a result, it is possible to make the traveling wind easier to flow toward the ECU by using the second cylinder located in front of the ECU, thereby efficiently cooling the ECU.
[0016]
According to the third aspect, if a battery is provided on the side surface of the shock absorber mounting portion, a heavy battery can be supported at the center of the vehicle body, so that mass can be concentrated and a wire harness can be formed. As long as possible.
[0017]
According to the fourth aspect, if the battery cover is provided with a peephole for the battery, the battery can be inspected while the vehicle body cover is still attached to the vehicle body, so that the inspection and maintenance are facilitated. In addition, since the traveling wind flowing backward inside the vehicle body passes through the viewing window to the outside, the traveling wind can be collected around the shock absorber, and as a result, the cooling efficiency of the shock absorber, which is a heat generating component, is improved. .
[0018]

A seat rail 26 extends obliquely upward and rearward on the top portion 12 of the shock absorber mounting portion 11, and a seat 28 is mounted on a seat cowl 27 supported by the seat rail 26.
[0030]
As is apparent from FIG. 3, a gap 30 is provided between the V-type engine 17 and the main frame 5, and an ECU 31, which is an electrical component for engine control, is accommodated in the gap 30. A bolt 32 is attached to a nut 32 provided on the side surface so as to protrude inward of the vehicle body.
[0031]
The gap 30 in which the ECU 31 is accommodated communicates with a space above the left cylinder 19 that projects obliquely downward and forward, and serves as a passage for the traveling wind W that is guided by the left cylinder 19 and easily flows in. ing.
[0032]
As is apparent from FIG. 1, the ECU 31 and the main frame 5 are overlapped in a side view, and a coupler 34 provided below the ECU 31 is provided at a lower end of the ECU 31 from the lower surface of the main frame 5 outward. I have.
