Abstract

An existing system for synchronizing the brakes of a tractor and a trailer is not suitable when a self-propelled vehicle, e.g. a self-propelled truck, is used as a trailer because it has no switching function. A system for braking the trailer with the inertia of a weight being generated through braking of the tractor is slow in response. A system of the inventor for synchronizing the accelerator disclosed in Laid-open No. 2003-118614 is not simple in structure and requires adjustment every time when the tractor and the trailer are coupled. The system for synchronizing traveling of the trailer, or the like, comprises a bar for coupling the tractor and the trailer extensibly,and controls the brake system and/or the accelerator of the trailer based on two systems; a means for detecting excess and deficiency in the braking power and/or the driving power of the trailer with respect to the tractor as a extensible displacement of the coupling bar, and a means for detecting brake operation or accelerating operation of the tractor in the form of an electric signal or a pneumatic signal.

発明を実施するための最良の形態  BEST MODE FOR CARRYING OUT THE INVENTION
以下図示する実施例により、 本発明に係るトレーラ等の走行同調装置の実施 の形態を説明する。  An embodiment of a travel tuning device such as a trailer according to the present invention will be described below with reference to the illustrated embodiment.
図 1 a乃至図 3 cに記載の実施例において、 本発明に係るトレーラ等の走行 同調装置において、 トラクタ 1とトレーラ 2は伸縮可能な連結バー 3によって 連結されている。 連結バー 3は、 トレーラ 2の前部に設けてあり、 その先端部 に設けたルネットアイ 1 5をトラクタ 1の後部に設けた連結フック 1 4に屈曲 可能且つ回動可能に連結することによって連結されいる。 また、 連結バー 3に は、 その伸縮変位を検出する検出手段が設けてあり、 トラクタ 1に対するトレ ーラ 2の制動力及び又は駆動力の過不足を、 連結バー 3の伸縮変位として検出 手段で検出し、 伸縮変位に基づいてトレーラ 2のブレーキ装置及び又はァクセ ル装置を制御するように構成してある。 In the embodiment shown in FIGS. 1a to 3c, the traveling of a trailer or the like according to the present invention In the tuning device, the tractor 1 and the trailer 2 are connected by a telescopic connecting bar 3. The connecting bar 3 is provided at a front portion of the trailer 2 and is connected by connecting a lunet eye 15 provided at a tip portion thereof to a connecting hook 14 provided at a rear portion of the tractor 1 so as to be bendable and rotatable. I have. Further, the connecting bar 3 is provided with a detecting means for detecting the expansion and contraction displacement of the connecting bar 3, and the detection means detects the excess or deficiency of the braking force and / or the driving force of the trailer 2 with respect to the tractor 1 as the expansion and contraction displacement of the connecting bar 3. It is configured to detect and control the brake device and / or the accelerator device of the trailer 2 based on the expansion and contraction displacement.
図 1 a〜図 3 cに記載の実施例の場合、 連結バー 3は、 全体として平面図で ほぼ V字状をなし、 トレーラ 2の前部から前方内側向きに設けた 2本のメイン アーム 1 2と、 このメインアーム 1 2にほぼ直交して水平な連結軸 8により相 互に屈曲可能に連結して設けた V字状のサブアーム 1 3とからなり、 サプア一 ム 1 3の先端にスライド軸部材 3 2 1とスライド軸受部材 3 2 0が設けてある。 スライド軸受部材 3 2 1はその先端部にルネットアイ 1 5を具備し、 トラクタ 1の後部に設けた連結フック 1 4に屈曲可能且つ回動可能に連結してあると共 に、 その軸部はスライド軸受部材 3 2 0を貫通して摺動自在に嵌合している。 スライド軸受部材 3 2 0を貫通したスライド軸部材 3 2 1の後端部にはフラ ンジ部 3 2 2が設けてあり、 フランジ部 3 2 2とスライド軸受部材 3 2 0の間、 及ぴスライド軸受部材 3 2 0とルネットアイ 1 5との間に、 拡張弾力を付勢し たスプリングコイル、 ゴム弾性部材、 又はそれらの組み合わせ等からなるバラ ンスバネ部材 3 2 3 , 3 2 4が設けてある。  In the case of the embodiment shown in FIGS. 1 a to 3 c, the connecting bar 3 has a substantially V-shape in plan view as a whole, and two main arms 1 provided inward from the front of the trailer 2 toward the front. 2 and a V-shaped sub-arm 13 that is connected to the main arm 12 at right angles to the main arm 12 so as to be able to bend with each other by a horizontal connecting shaft 8, and slides to the tip of the sub-arm 13. A shaft member 3 21 and a slide bearing member 3 20 are provided. The slide bearing member 3 21 has a lunette eye 15 at the tip thereof, and is connected to a connecting hook 14 provided at the rear of the tractor 1 so as to be able to bend and rotate, and the shaft portion slides. It slidably fits through the bearing member 320. A flange portion 3222 is provided at the rear end of the slide shaft member 3221 penetrating the slide bearing member 320, and between the flange portion 322 and the slide bearing member 320, and a slide. Between the bearing member 320 and the lunette eye 15, there are provided balance spring members 322, 324 made of a spring coil, a rubber elastic member, or a combination thereof, which urges the extended elasticity.
そして、 例えば、 トラクタが加速するときには、 連結パー 3には引っ張り力 が働いて伸張し、 スライド軸部材 3 2 1はスライド軸受部材 3 2 0から前方に 突出してバランスパネ部材 3 2 3が圧縮されてその反力によりスライド軸部材 3 2 1を中立位置に押し戻そうとし、 逆に、 トラクタが減速するときには、 連 結バー 3に圧縮力が働いて、 スライド軸部材 3 2 1はスライド軸受部材 3 2 0 から後方に突出してバランスバネ部材 3 2 4が圧縮されてその反力によりスラ ィド軸部材 3 2 1を中立位置に押し戻そうと作用するように構成してある。 バランスバネ部材 3 2 3， 3 2 4の強度により連結バー 3の伸縮変位の大小 は設定され、 ばね強度が比較的弱く伸縮変位が大きい場合はその変位を機械的 に検出することが適し、 ばね強度が比較的強くて伸縮変位が小さい場合や、 バ ランスバネ部材を使用しないで連結バー 3に生じる応力変化を検出する場合に は、 ス トレンゲージ等の感圧部材ゃ微少変位検出計等の電気的な方法によって 検出することが適している。 For example, when the tractor accelerates, the connecting par 3 is extended by a tensile force, and the slide shaft member 3 21 projects forward from the slide bearing member 3 20 to compress the balance panel member 3 2 3. When the tractor decelerates, a compressive force acts on the connecting bar 3, and the slide shaft member 3 2 1 becomes the slide bearing member 3. The balance spring member 324 is protruded rearward from 20 and is compressed so as to act to push the slide shaft member 321 back to the neutral position by its reaction force. The magnitude of the expansion and contraction displacement of the connecting bar 3 is set by the strength of the balance spring members 3 2 3 and 3 2 4. If the spring strength is relatively weak and the expansion and contraction displacement is large, it is appropriate to detect the displacement mechanically. When the strength is relatively strong and the expansion / contraction displacement is small, or when detecting a change in stress occurring in the connecting bar 3 without using a balance spring member. Is suitable to be detected by an electric method such as a pressure-sensitive member such as a strain gauge or a micro-displacement detector.
