Description

本考案は、貨物自動車の過積載を防止するための装置に関する。  The present invention relates to an apparatus for preventing overloading of a truck.

従来の貨物自動車用の過積載防止装置には、安価なタイプとして、荷台フレームと後輪車軸アクスルとの隙間の距離が、荷重がかかることにより狭まることを利用して、後輪車軸アクスルの中央上部に直接取り付けたレールの先端を、回動するロッドやレバーに連結し、そのレバーと一体化して回動する光遮断部材が、荷台フレーム側に取り付けたセンサの発光部と受光部の間を通り、あらかじめ設定された位置で、光を遮った時に、警報装置が作動し、過積載を知らせることを特徴とした過積載防止装置がある。また、高価なタイプとしては、前輪の２カ所と後輪の２カ所のタイヤ付近の荷台フレームと車軸アクスルに、回動する様にリンクバーをそれぞれ直接取り付け、そのリンクバーの先端を回動する様に、それぞれ連結し、その４カ所の連結部分に、それぞれ角度測定センサを取り付けて、それぞれで測定された測定値の平均値に基づいて積載物の重量を演算し、設定荷重に達した時に、警報装置が作動し、過積載を知らせることを特徴とした過積載防止装置がある。  The conventional overload prevention device for trucks is an inexpensive type that uses the fact that the gap distance between the loading platform frame and the rear axle axle is narrowed by the applied load, so that the center of the rear axle axle is reduced. The tip of the rail attached directly to the top is connected to a rotating rod or lever, and the light blocking member that rotates integrally with the lever is located between the light emitting part and the light receiving part of the sensor attached to the loading frame. As described above, there is an overload prevention device characterized in that an alarm device is activated to notify overloading when light is blocked at a preset position. Moreover, as an expensive type, a link bar is directly attached to the loading frame and the axle axle in the vicinity of the tires at the two positions of the front wheel and the two positions of the rear wheel, and the tip of the link bar is rotated. In the same way, connect the angle measurement sensors to the four connecting parts, calculate the weight of the load based on the average value of the measured values, and reach the set load. There is an overload prevention device characterized in that an alarm device is activated to notify overloading.

しかしながら、以上の技術によれば、過積載防止装置の各部材が車軸アクスルに連結されており、そのため、走行中の激しい振動が常に、各部材に伝わることとなり、各部材に変形、摩耗、破損などが生じ、耐久性の問題がある。また、後輪車軸アクスルには、ブレーキオイルパイプが配管されており、万一、部材の破損が生じた場合に、ブレーキシステムへの損傷が生じるおそれがあり、安全性の問題がある。さらに、過積載防止装置の設置場所は車輪の近くであり、雨天走行の時の泥水の飛散など、汚れやすく、そのため、センサが測定精度が低下したり、測定不能になるなど、汚れ対策の問題もある。また、過積載防止装置の設置場所は、車両の下部であり、車種により様々な設置位置となり、その取り付けや荷重設定、荷重設定変更の時に、作業の困難性の問題がある。
そこで、本考案は、過積載防止装置の耐久性・安全性・汚れ対策・作業の困難性のそれぞれの問題を解決する過積載防止装置を提供することを課題とする。However, according to the above technique, each member of the overload prevention device is connected to the axle axle, so that severe vibration during traveling is always transmitted to each member, causing deformation, wear, and damage to each member. As a result, there is a problem of durability. Further, the rear axle axle is provided with a brake oil pipe, and in the unlikely event that a member is damaged, there is a risk of damage to the brake system, resulting in a safety problem. In addition, the location of the overload prevention device is near the wheel, and it is easy to get dirty, such as splashing of muddy water during rainy weather. There is also. Also, the installation location of the overload prevention device is at the lower part of the vehicle, and it is in various installation positions depending on the vehicle type, and there is a problem of difficulty in work at the time of installation, load setting, and load setting change.
Therefore, an object of the present invention is to provide an overload prevention device that solves the problems of durability, safety, countermeasures against dirt, and difficulty in work of the overload prevention device.

以上の課題を解決するために、貨物自動車の後輪車軸アクスルの中央部上方で、後輪荷台フレーム間を連結するクロスバーに取り付けた距離測定センサと、同距離測定センサに内蔵され前記後輪車軸アクスルの中央部上部と前記距離測定センサの測定部との距離を予め設定した測定記録部と、同測定記録部の設定した測定距離以内になった時に作動する警報装置を前記距離測定センサに内蔵もしくは連動させたことを特徴とする過積載防止装置で、更に、上記距離測定センサに汚れ防止カバーを設置した。加えて、上記距離測定センサに前記後輪車軸アクスルの中央部上部と前記距離測定センサの測定部との距離を設定変更可能にした測定記録設定変更部を設置した。  In order to solve the above problems, a distance measuring sensor attached to a crossbar connecting the rear wheel carrier frames above the center of the rear axle axle of the lorry, and the rear wheel incorporated in the distance measuring sensor. A measurement recording unit in which the distance between the upper center portion of the axle axle and the measurement unit of the distance measurement sensor is set in advance, and an alarm device that is activated when the distance is within the measurement distance set by the measurement recording unit in the distance measurement sensor. The anti-loading device is built-in or interlocked with the anti-loading device, and a dirt prevention cover is installed on the distance measuring sensor. In addition, the distance measurement sensor is provided with a measurement record setting change unit that can change the setting of the distance between the upper center portion of the rear axle axle and the measurement unit of the distance measurement sensor.

第１考案によれば、距離測定センサなどの過積載防止装置の各部材は、後輪車軸アクスルの中央部上部と距離がはなれており、走行中の同後輪車軸アクスルの激しい振動を直接に受けることがなく、そのため、各部材の変形、摩耗、破損のおそれがなく、耐久性の問題が解決できた。同時に、各部材の破損によるブレーキシステムへの損傷のおそれもなくなり、安全性の問題も解決できた。
第２考案によれば、前記距離測定センサに汚れ防止カバーを設置したことにより、雨天走行の時の泥水の飛散などによる汚れで、同距離測定センサが測定精度が低下したり測定不能になることを防げるので汚れ対策の問題が解決できた。
第１考案と第３考案によれば、前記後輪車軸アクスルに、前記距離測定センサなどの過積載防止装置の部材を直接加工取り付けする手間がなくなり、過積載防止装置の設置が簡単になった。また、測定記録設定変更部を作業しやすい場所に設置したことにより、同後輪車軸アクスルの中央部上部と同距離測定センサの測定部との距離設定や距離設定変更を簡単に行うことができ、車両の下部での作業が軽減できた。これらのことにより、作業の困難性が解決できた。According to the first device, each member of the overload prevention device such as the distance measuring sensor is separated from the upper part of the center part of the rear axle axle so that the vibration of the rear axle axle during traveling is directly affected. Therefore, there was no fear of deformation, wear, or breakage of each member, and the problem of durability could be solved. At the same time, there was no risk of damage to the brake system due to breakage of each member, and the safety problem could be solved.
According to the second device, by installing a dirt prevention cover on the distance measurement sensor, the measurement accuracy of the distance measurement sensor is lowered or becomes impossible to measure due to dirt due to scattering of muddy water during rainy weather.

本考案の一実施形態を示す斜視図である。It is a perspective view showing one embodiment of the present invention.

本考案の一実施形態を、図１に示す。
貨物自動車の後輪車軸アクスル５の中央部上方で、後輪荷台フレーム６間を連結するクロスバー７に距離測定センサ１を設置した。この時、後輪車軸アクスル５の中央部上部と距離測定センサ１の測定部との距離は、後輪車軸アクスル５の走行中の激しい振動が距離測定センサ１などの過積載防止装置の部材に直接伝わることがない様に十分にあけた距離とした。なお、距離測定センサ１は、後輪車軸アクスル５の中央部上部と距離測定センサ１の測定部との距離を測定記録設定できるセンサを使用した。また、距離測定センサ１をクロスバー７に固定する方法として自在取り付けステー３を用いた。自在取り付けステー３は、長穴などを利用して距離測定センサ１の位置を前後、左右、上下に調整できるステーである。また、荷物の積み込みにより、後輪車軸アクスル５の中央部上部と距離測定センサ１の測定部との距離が、距離測定センサ１に内蔵された測定記録部に予め設定した後輪車軸アクスル５の中央部上部と距離測定センサ１の測定部との距離以内になった時に作動する図示省略の警報装置を運転席と車両外装部の作業中の作業員にもわかる位置に設置した。警報装置は、作動したことを警報ランプと警報ブザーで知らせる。警報装置のブザーには図示省略のＯＮ−ＯＦＦスイッチを取り付けた。また、距離測定センサ１に汚れ防止カバー２を設置した。汚れ防止カバー２は、後輪車軸アクスル５の走行中の激しい振動を吸収して、距離測定センサ１などの過積載防止装置の各部材に、その振動による影響をほとんど与えない様なクッション性のある形状のゴムカバーを使用した。また、作業しやすい位置に測定記録設定変更部４を設置した。同測定記録設定変更部４は、後輪車軸アクスル５の中央部上部と前記距離測定センサ１の測定部との距離設定や距離設定変更を押しボタンスイッチを押すことにより簡単にできる装置である。One embodiment of the present invention is shown in FIG.
The distance measuring sensor 1 is installed on the cross bar 7 that connects the rear wheel carrier frames 6 above the center of the rear axle axle 5 of the lorry. At this time, the distance between the upper center portion of the rear axle axle 5 and the measuring portion of the distance measuring sensor 1 is that the intense vibration during the traveling of the rear axle axle 5 is applied to the members of the overload prevention device such as the distance measuring sensor 1. The distance was sufficiently wide enough not to be transmitted directly. As the distance measuring sensor 1, a sensor capable of measuring and setting the distance between the upper center portion of the rear axle axle 5 and the measuring portion of the distance measuring sensor 1 was used. Further, as a method for fixing the distance measuring sensor 1 to the cross bar 7, a freely attaching stay 3 was used. The universal mounting stay 3 is a stay that can adjust the position of the distance measuring sensor 1 forward / backward, left / right, and up / down using a slot or the like. Further, by loading the luggage, the distance between the upper center portion of the rear axle axle 5 and the measuring section of the distance measuring sensor 1 is set in the measurement recording section built in the distance measuring sensor 1 in advance. An alarm device (not shown) that operates when the distance between the center upper part and the measuring part of the distance measuring sensor 1 is within the distance is installed at a position that can be understood by workers working in the driver's seat and the vehicle exterior part. The alarm device notifies that it has been activated by an alarm lamp and an alarm buzzer. An ON-OFF switch (not shown) was attached to the buzzer of the alarm device. Further, a dirt prevention cover 2 is installed on the distance measuring sensor 1. The anti-smudge cover 2 absorbs intense vibrations during traveling of the rear axle axle 5 and has a cushioning property such that each member of the overload prevention device such as the distance measuring sensor 1 hardly affects the vibrations. A rubber cover with a certain shape was used. In addition, the measurement record setting changing unit 4 is installed at a position where it is easy to work. The measurement record setting change unit 4 is a device that can easily change the distance setting or the distance setting change between the center upper part of the rear axle axle 5 and the measurement unit of the distance measuring sensor 1 by pressing a push button switch.

「実施形態の効果」
本実施形態によれば、距離測定センサ１などの過積載防止装置の各部材は、後輪車軸アクスル５の中央部上部と距離がはなれており、走行中の後輪車軸アクスル５の激しい振動を直接に受けることがなく、そのため、各部材の変形、摩耗、破損のおそれがなく、耐久性の問題が解決できた。同時に、各部材の破損によるブレーキシステムへの損傷のおそれもなくなり、安全性の問題も解決できた。
また、距離測定センサ１に汚れ防止カバー２を設置したことにより、雨天走行の時の泥水の飛散などによる汚れで、距離測定センサ１が測定精度が低下したり測定不能になることを防げるので汚れ対策の問題が解決できた。
さらに、後輪車軸アクスル５に、距離測定センサ１などの過積載防止装置の各部材を直接加工取り付けする手間がなくなり、過積載防止装置の設置が簡単になった。また、自在取り付けステー３を使用することにより、車種別に個別に取り付けステーを作る手間がなくなった。また、測定記録設定変更部４を作業しやすい場所に設置したことにより、後輪車軸アクスル５の中央部上部と距離測定センサ１の測定部との距離設定や距離設定変更を簡単に行うことができ、車両の下部での作業が軽減できた。これらのことにより、作業の困難性が解決できた。また、普及の妨げとなっている問題として、安価なタイプは精度が低く、高価なタイプは精度は高いが価格が高すぎるという問題がある。本過積載防止装置は安価なタイプで精度も高く、前記価格の問題も解決できた。実証テストを実施したところ設定値が２０８０ｋｇに対して警報装置が２０２０ｋｇから２１４０ｋｇの間で作動した。この結果、誤差が設定値の前後３％以内となった。（テスト条件：塵芥収集車２トン車、平坦地、１２回テスト実施、各回１９００ｋｇ荷重時より積み込み開始、２０ｋｇ毎積み込み×２回、４０ｋｇ毎積み込み×２回、６０ｋｇ毎積み込み×２回、８０ｋｇ毎積み込み×２回、１００ｋｇ毎積み込み×２回、１２０ｋｇ毎積み込み×２回、それぞれの積み込み重量で警報装置が作動するまで積み込みを続けた。それぞれの積み込み重量で積み込み毎に振動を与えた＝走行時の振動を想定したため）また、本実施形態では、後輪車軸アクスル５の中央部上部と距離測定センサ１の測定部との距離設定及び距離測定を行う時、後輪車軸アクスル５の中央部上方に、距離測定センサ１の測定部を設置する様にした。これは、後輪車軸アクスル５の中央部上方以外は、端にずれるほど、荷重の偏りによる測定値の誤差が大きくなるという理由と、後輪車軸アクスル５の中央部上方以外は、汚れ防止の対策が難しいという理由からである。
「他の実施形態」
図１の実施形態では、距離測定センサ１を自在取り付けステー３を用いて固定しているが、他の実施形態では、距離測定センサ１を適切な位置に固定できるならば、直接、クロスバー７に固定するなど、自在取り付けステー３を用いないものでも良い。また、図１の実施形態では、汚れ防止カバー２にゴムカバーを使用しているが、他の実施形態では、クッション性があれば、他の素材のカバーでも良い。また、図１の実施形態では、測定記録設定変更部４に、押しボタンスイッチを使用しているが、他の実施形態では、ＯＮ−ＯＦＦ機能があればトグルスイッチなど他のスイッチを使用しても良い。"Effect of the embodiment"
According to the present embodiment, each member of the overload prevention device such as the distance measurement sensor 1 is separated from the upper part of the center portion of the rear axle axle 5 and is subjected to severe vibration of the rear axle axle 5 during traveling. There was no direct impact, so there was no risk of deformation, wear or breakage of each member, and the problem of durability could be solved. At the same time, there was no risk of damage to the brake system due to breakage of each member, and the safety problem could be solved.
In addition, since the dirt measurement cover 2 is installed on the distance measuring sensor 1, it is possible to prevent the distance measuring sensor 1 from being deteriorated in measurement accuracy or being unable to be measured due to dirt due to muddy water scattering during rainy weather. The problem of the countermeasure was solved.
Furthermore, there is no need to directly process and attach each member of the overload prevention device such as the distance measuring sensor 1 to the rear axle axle 5 and the installation of the overload prevention device is simplified. In addition, the use of the universal mounting stay 3 eliminates the trouble of making a mounting stay for each vehicle type. In addition, by installing the measurement record setting changing unit 4 in a place where it is easy to work, it is possible to easily perform the distance setting and the distance setting change between the center upper part of the rear axle axle 5 and the measuring unit of the distance measuring sensor 1. It was possible to reduce the work at the bottom of the vehicle. By these things, the difficulty of work was solved. Further, as a problem that hinders the spread, there is a problem that an inexpensive type has low accuracy, and an expensive type has high accuracy but is too expensive. This overload prevention device is an inexpensive type with high accuracy and can solve the price problem. As a result of the demonstration test, the alarm device operated between 2020 kg and 2140 kg with respect to the set value of 2080 kg. As a result, the error was within 3% before and after the set value. (Test conditions: garbage truck 2 ton car, flat ground, 12 tests, loading started from 1900kg load each time, 20kg loading x 2 times, 40kg loading x 2 times, 60kg loading x 2 times, every 80kg Loading twice, 100 kg loading twice, 120 kg loading x 2 times, and loading continued until the alarming device was activated at each loading weight. In this embodiment, when the distance between the upper center portion of the rear axle axle 5 and the measuring portion of the distance measuring sensor 1 is set and the distance is measured, the upper center portion of the rear axle axle 5 is In addition, the measuring unit of the distance measuring sensor 1 is installed. This is because the error in the measured value due to the load bias increases as the distance to the end other than above the center part of the rear axle axle 5 is increased, and dirt is prevented except for the upper part of the rear axle axle 5. This is because countermeasures are difficult.
"Other embodiments"
In the embodiment of FIG. 1, the distance measuring sensor 1 is fixed using the universal mounting stay 3. However, in other embodiments, if the distance measuring sensor 1 can be fixed at an appropriate position, the crossbar 7 is directly connected. It is also possible to use one that does not use the universal mounting stay 3 such as fixing to the frame. Further, in the embodiment of FIG. 1, a rubber cover is used for the dirt prevention cover 2, but in other embodiments, a cover made of other materials may be used as long as it has cushioning properties. In the embodiment of FIG. 1, a push button switch is used for the measurement record setting changing unit 4. However, in other embodiments, if there is an ON-OFF function, another switch such as a toggle switch is used. Also good.
