Description

本発明は、機械に現在貯留している潤滑油若しくは作動油の量を確認するためのオイルレベルゲージの構造に関する。 The present invention relates to the structure of an oil level gauge for checking the amount of lubricating oil or hydraulic oil currently stored in a machine.

車両等に搭載される内燃機関は、その各所を潤滑するとともに当該内燃機関に付随する機構、例えば吸排気バルブの開閉タイミングを変化させるVVT(Variable Valve Timing)機構等を作動させる潤滑油兼作動油であるエンジンオイルを、クランクケース下方のオイルパンに貯留している。エンジンオイルの量は、内燃機関を運転することで徐々に減少してゆく。エンジンオイルの量が不足すると、内燃機関の正常な稼働に支障を来すおそれが生じる。そこで、内燃機関には、当該内燃機関の内部に挿入して現在のエンジンオイルの量を計るためのオイルレベルゲージが付帯している(例えば、下記特許文献1を参照)。 An internal combustion engine mounted on a vehicle or the like is a lubricating oil and a hydraulic oil that lubricates various parts thereof and operates a mechanism associated with the internal combustion engine, for example, a VVT (Variable Valve Timing) mechanism that changes the opening / closing timing of an intake / exhaust valve. The engine oil is stored in the oil pan below the crankcase. The amount of engine oil gradually decreases as the internal combustion engine is operated. If the amount of engine oil is insufficient, the normal operation of the internal combustion engine may be hindered. Therefore, the internal combustion engine is provided with an oil level gauge that is inserted into the internal combustion engine to measure the current amount of engine oil (see, for example, Patent Document 1 below).

内燃機関のクランクシャフトと駆動輪が取り付けられた車軸との間に介在する変速機においても、潤滑油兼作動油であるトランスミッションフルードをオイルパンに貯留している。そして、そのトランスミッションフルードの量を計るためのオイルレベルゲージが付帯している(例えば、下記特許文献2を参照)。 The transmission fluid, which is both lubricating oil and hydraulic oil, is also stored in the oil pan in the transmission that is interposed between the crankshaft of the internal combustion engine and the axle to which the drive wheels are attached. An oil level gauge for measuring the amount of the transmission fluid is attached (see, for example, Patent Document 2 below).

オイルレベルゲージを挿入する対象の機械内には、管状のゲージガイドを設けていることが多い。内燃機関であれば、シリンダヘッド、シリンダブロック及びクランクケースを貫いて伸長したゲージガイドが内包され、その上端がシリンダヘッドカバーに開口する一方、その下端がオイルパンの底部近傍にまで達している。オイルレベルゲージを対象の機械に装備するときには、オイルレベルゲージの把手と一体化した栓部を、ゲージガイドの上端にある入口孔に嵌入して固着する。 A tubular gauge guide is often provided in the machine into which the oil level gauge is inserted. In the case of an internal combustion engine, a gauge guide extending through the cylinder head, the cylinder block and the crankcase is included, and the upper end thereof opens to the cylinder head cover, while the lower end reaches the vicinity of the bottom of the oil pan. When equipping the target machine with the oil level gauge, the stopper integrated with the handle of the oil level gauge is fitted into the inlet hole at the upper end of the gauge guide and fixed.

潤滑油若しくは作動油の油面に浸るオイルレベルゲージの本体、及びゲージ本体を挿通するゲージガイドは、金属製である。他方、ゲージ本体の基端部に接続している把手及び栓部は、樹脂成形品である。金属と樹脂とでは、熱膨張率が異なる。そのため、極低温の環境下において、ゲージガイドの入口孔に嵌入していた栓部が入口孔から抜出してしまうことが懸念される。 The main body of the oil level gauge soaked in the oil surface of the lubricating oil or hydraulic oil, and the gauge guide through which the gauge main body is inserted are made of metal. On the other hand, the handle and the stopper connected to the base end of the gauge body are resin molded products. The coefficient of thermal expansion differs between metal and resin. Therefore, in an extremely low temperature environment, there is a concern that the plug portion fitted in the inlet hole of the gauge guide may be pulled out from the inlet hole.

以上の問題に初めて着目してなされた本発明は、オイルレベルゲージの栓部がゲージガイドの入口孔から意図せず抜出してしまうことを抑止しようとするものである。 The present invention, which has been focused on the above problems for the first time, is intended to prevent the plug portion of the oil level gauge from being unintentionally pulled out from the inlet hole of the gauge guide.

本発明は、潤滑油若しくは作動油を貯留している機械のハウジングの内部に挿入して当該ハウジング内の潤滑油若しくは作動油の量を確認するオイルレベルゲージの構造であって、先端部が潤滑油若しくは作動油の油面よりも下方に没入するゲージ本体と、機械のハウジングの内部に設けた前記ゲージ本体を挿通するゲージガイドと、前記ゲージ本体の基端部に接続し前記ゲージガイドの入口孔に嵌入する栓部を有している把手と、前記ゲージ本体の一部を屈曲させて形成した屈曲部と、前記ゲージガイドの一部の内径をそれに隣接する箇所と比較して縮径または拡径させて形成した、前記栓部が前記入口孔に嵌入している状態で前記屈曲部が係合する抜止部とを具備してなる。 The present invention is a structure of an oil level gauge that is inserted into the housing of a machine that stores lubricating oil or hydraulic oil to check the amount of lubricating oil or hydraulic oil in the housing, and the tip is lubricated. A gauge body that immerses below the oil level of oil or hydraulic oil, a gauge guide that inserts the gauge body provided inside the housing of the machine, and an inlet of the gauge guide that is connected to the base end of the gauge body. A handle having a plug portion to be fitted into the hole, a bent portion formed by bending a part of the gauge body, and an inner diameter of a part of the gauge guide are reduced in diameter or reduced in comparison with a portion adjacent thereto. It is provided with a retaining portion formed by expanding the diameter, in which the bent portion engages with the plug portion fitted in the inlet hole.

本発明によれば、オイルレベルゲージの栓部がゲージガイドの入口孔から意図せず抜出してしまうことを抑止できる。 According to the present invention, it is possible to prevent the plug portion of the oil level gauge from being unintentionally pulled out from the inlet hole of the gauge guide.

本発明の一実施形態を、図面を参照して説明する。図1に、本実施形態におけるオイルレベルゲージの構造を示す。本実施形態のオイルレベルゲージは、機械である内燃機関に付帯し、同内燃機関のハウジング内即ちオイルパンに蓄えられている潤滑油兼作動油であるエンジンオイルの量を確認するために使用される。 An embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows the structure of the oil level gauge in this embodiment. The oil level gauge of the present embodiment is attached to the internal combustion engine which is a machine, and is used to check the amount of engine oil which is a lubricating oil and hydraulic oil stored in the housing of the internal combustion engine, that is, in the oil pan. NS.

オイルレベルゲージの本体1は、細く長尺な帯状をなす、例えばステンレス合金等の金属材料を用いて作製した可撓体である。ゲージ本体1は、内燃機関のハウジングを構成するシリンダヘッドカバー、シリンダヘッド、シリンダブロック及びクランクケースを貫く管状のゲージガイド3に、入口孔31を介して上方から差し込まれる。入口孔31は通常、シリンダヘッドカバーに開口している。 The main body 1 of the oil level gauge is a flexible body having a long and thin strip shape, for example, made of a metal material such as a stainless alloy. The gauge body 1 is inserted into a tubular gauge guide 3 that penetrates a cylinder head cover, a cylinder head, a cylinder block, and a crankcase that constitute a housing of an internal combustion engine from above through an inlet hole 31. The inlet hole 31 is usually open to the cylinder head cover.

そして、ゲージ本体1の先端部即ち下端部が、オイルパンに蓄えられたエンジンオイルの油面よりも下方に没入する。その下端部に付着したエンジンオイルの分量、つまり上下方向に沿った幅を視認することにより、現在のオイルパン内のエンジンオイルの量を計測することができる。 Then, the tip end portion, that is, the lower end portion of the gauge body 1 is immersed below the oil level of the engine oil stored in the oil pan. By visually recognizing the amount of engine oil adhering to the lower end portion, that is, the width along the vertical direction, the amount of engine oil in the current oil pan can be measured.

ゲージガイド3は、長尺な管状をなす、例えばステンレス合金等の金属材料を用いて作製した部材である。本実施形態における内燃機関は、縦型のものではあるが、気筒のシリンダボアの軸線を鉛直方向から大きく傾倒させた姿勢で車両等に搭載する、いわゆるスラントエンジンである。それ故、図1に示しているように、ゲージガイド3は、その基端即ち上端にある入口孔31から水平に近い斜め下方に伸長し、その後鉛直下方に向けて湾曲した形状をなしている。ゲージガイド3に挿通されるゲージ本体1もまた、ゲージガイド3内でこれに対応した湾曲形状に撓み変形する。 The gauge guide 3 is a member having a long tubular shape and made of a metal material such as a stainless alloy. Although the internal combustion engine in the present embodiment is a vertical type, it is a so-called slant engine mounted on a vehicle or the like in a posture in which the axis of the cylinder bore of the cylinder is greatly tilted from the vertical direction. Therefore, as shown in FIG. 1, the gauge guide 3 has a shape that extends diagonally downward near the horizontal from the inlet hole 31 at its base end, that is, the upper end, and then curves vertically downward. .. The gauge body 1 inserted through the gauge guide 3 also bends and deforms into a corresponding curved shape in the gauge guide 3.

ゲージ本体1の基端部即ち上端部には、オイルレベルゲージを抜き差し操作するユーザが把持することのできる把手2を固定している。この把手2の下部には、栓部21を一体的に設けている。栓部21を含む把手2は、例えば合成樹脂材料を用いて作製した一体成形品である。栓部21は、ゲージガイド3の上端の入口孔31に嵌入して、その孔31を気密に閉塞する。栓部21の外周には、ゲージガイド3の内周に密着するシール材であるOリング22を装着している。 A handle 2 that can be gripped by a user who inserts and removes the oil level gauge is fixed to the base end portion, that is, the upper end portion of the gauge body 1. A plug portion 21 is integrally provided at the lower portion of the handle 2. The handle 2 including the stopper 21 is an integrally molded product manufactured by using, for example, a synthetic resin material. The plug portion 21 is fitted into the inlet hole 31 at the upper end of the gauge guide 3 and airtightly closes the hole 31. An O-ring 22 which is a sealing material that adheres to the inner circumference of the gauge guide 3 is attached to the outer circumference of the stopper portion 21.

既に述べた通り、本実施形態では、ゲージガイド3が大きく湾曲しており、ゲージガイド3内に差し込まれるゲージ本体1もまたゲージガイド3に沿って大きく湾曲するように弾性変形する。つまるところ、ゲージ本体1が板ばねのような作用を営む。その帰結として、ゲージガイド3の入口孔31に嵌入している栓部21には、当該入口孔31から押し出されるような力が作用する。 As described above, in the present embodiment, the gauge guide 3 is greatly curved, and the gauge body 1 inserted into the gauge guide 3 is also elastically deformed so as to be greatly curved along the gauge guide 3. After all, the gauge body 1 acts like a leaf spring. As a result, a force that pushes out from the inlet hole 31 acts on the plug portion 21 that is fitted into the inlet hole 31 of the gauge guide 3.

しかも、ゲージ本体1及びゲージガイド3は金属製であり、把手2及び栓部21は樹脂製であって、金属と樹脂とでは熱膨張率(線膨張率や体積膨張率)が相異する。このため、特に極低温の環境下において、ゲージガイド3の入口孔31に嵌入していた栓部21が入口孔31から抜出する懸念が生じる。 Moreover, the gauge body 1 and the gauge guide 3 are made of metal, and the handle 2 and the stopper 21 are made of resin, and the coefficient of thermal expansion (linear expansion rate and volume expansion rate) differs between the metal and the resin. Therefore, there is a concern that the plug portion 21 fitted in the inlet hole 31 of the gauge guide 3 may be pulled out from the inlet hole 31 particularly in an extremely low temperature environment.

そこで、本実施形態では、図1に示しているように、ゲージ本体1の一部に、これを三角波状に屈曲させた屈曲部11を形成する一方、ゲージガイド3の一部に、内径をその隣接箇所と比較して縮小させた抜止部32を形成している。栓部21が入口孔31に嵌入している状態で、ゲージ本体1の屈曲部11は、ゲージガイド3における抜止部32よりも内奥に位置しており、その抜止部32に係合する。しかも、屈曲部11の山となった部位が、ゲージガイド3の内周に当接または密接する。これらが相まって、栓部21が入口孔31から抜出することを抑制する抜け止めとなる。 Therefore, in the present embodiment, as shown in FIG. 1, a bent portion 11 formed by bending the gauge body 1 in a triangular wave shape is formed on a part of the gauge body 1, while an inner diameter is formed on a part of the gauge guide 3. A retaining portion 32 that is reduced in size as compared with the adjacent portion is formed. In a state where the plug portion 21 is fitted into the inlet hole 31, the bent portion 11 of the gauge body 1 is located inwardly behind the retaining portion 32 in the gauge guide 3 and engages with the retaining portion 32. Moreover, the mountainous portion of the bent portion 11 comes into contact with or comes into close contact with the inner circumference of the gauge guide 3. Together, these serve as a retainer that prevents the plug 21 from coming out of the inlet hole 31.

本実施形態では、潤滑油若しくは作動油(エンジンオイル)を貯留している機械(内燃機関)のハウジング(シリンダヘッドカバー、シリンダヘッド、シリンダブロック及びクランクケース)の内部に挿入して当該ハウジング内の潤滑油若しくは作動油の量を確認するオイルレベルゲージの構造であって、先端部が潤滑油若しくは作動油の油面よりも下方に没入するゲージ本体1と、機械のハウジングの内部に設けた前記ゲージ本体1を挿通するゲージガイド3と、前記ゲージ本体1の基端部に接続し前記ゲージガイド3の入口孔31に嵌入する栓部21を有している把手2と、前記ゲージ本体1の一部を屈曲させて形成した屈曲部11と、前記ゲージガイド3の一部の内径をそれに隣接する箇所と比較して縮径させて形成した、前記栓部21が前記入口孔31に嵌入している状態で前記屈曲部11が係合する抜止部32とを具備するオイルレベルゲージの構造を構成した。本実施形態によれば、オイルレベルゲージの栓部21がゲージガイド3の入口孔31から意図せず抜出してしまうことを適切に防止できる。 In the present embodiment, the lubricating oil or hydraulic oil (engine oil) is stored inside the housing (cylinder head cover, cylinder head, cylinder block and crank case) of the machine (internal engine) to lubricate the inside of the housing. The structure of the oil level gauge for checking the amount of oil or hydraulic oil, the gauge body 1 whose tip is immersed below the oil level of the lubricating oil or hydraulic oil, and the gauge provided inside the housing of the machine. A gauge guide 3 through which the main body 1 is inserted, a handle 2 having a plug portion 21 connected to the base end portion of the gauge main body 1 and fitted into the inlet hole 31 of the gauge guide 3, and one of the gauge main bodies 1. The bent portion 11 formed by bending the portion and the plug portion 21 formed by reducing the inner diameter of a part of the gauge guide 3 with respect to a portion adjacent thereto are fitted into the inlet hole 31. The structure of the oil level gauge is configured to include the retaining portion 32 with which the bent portion 11 is engaged. According to this embodiment, it is possible to appropriately prevent the plug portion 21 of the oil level gauge from being unintentionally pulled out from the inlet hole 31 of the gauge guide 3.

なお、本発明は以上に詳述した実施形態に限られるものではない。上記実施形態では、ゲージガイド3の一部の内径を縮小した抜止部32を形成していたが、図2に示すように、ゲージガイド3の一部の内径をそれに連接する箇所よりも拡大させた抜止部32を形成することも考えられる。この場合、ゲージ本体1の屈曲部11の山となった部位が、拡開する抜止部32の内周に嵌まるように係合して、栓部21が入口孔31から抜出することを抑制する抜け止めとなる。 The present invention is not limited to the embodiments described in detail above. In the above embodiment, the retaining portion 32 is formed by reducing the inner diameter of a part of the gauge guide 3, but as shown in FIG. 2, the inner diameter of a part of the gauge guide 3 is enlarged beyond the portion connected to the retaining portion 32. It is also conceivable to form a retaining portion 32. In this case, the mountainous portion of the bent portion 11 of the gauge body 1 is engaged so as to fit into the inner circumference of the expanding retaining portion 32, and the plug portion 21 is ejected from the inlet hole 31. It will be a restraint to prevent it from coming off.

上記実施形態では、機械として内燃機関を想定し、オイルレベルゲージがオイルパンに蓄えられたエンジンオイルの量を計測するものであった、だが、本発明の適用対象は、内燃機関のオイルレベルゲージには限定されない。例えば、機械として自動変速機等を想定し、オイルレベルゲージがオイルパンに蓄えられたトランスミッションフルード等の量を計測するものであっても構わないことは言うまでもない。 In the above embodiment, an internal combustion engine is assumed as a machine, and the oil level gauge measures the amount of engine oil stored in the oil pan. However, the subject of the present invention is the oil level gauge of the internal combustion engine. Not limited to. For example, it goes without saying that an automatic transmission or the like may be assumed as a machine and the oil level gauge may measure the amount of transmission fluid or the like stored in the oil pan.

その他、各部の具体的な構成は、本発明の趣旨を逸脱しない範囲で種々変形が可能である。 In addition, the specific configuration of each part can be variously modified without departing from the spirit of the present invention.
