Abstract

Floor provided with pneumatic springs, in which low-pressure pneumatic springs are mounted in array on the floor in a passenger's compartment of a train, bus, motorcar or a driver's compartment of a track, etc. to thereby absorb the simultaneous vibrations of the body and the floor by the pneumatic springs. This low-pressure pneumatic spring is made of a molded two-ply rubber layer in which two sheets of cloth are buried in rubber, and has rugged upper surface to prevent passengers from slipping. This spring is filled with the air of 0.5 to 0.8 kg/cm2. According to this invention, the low-pressure pneumatic springs are installed at the positions which are not concerned with the weigth of the vehicle body to thereby eliminate the faults due to high pressure in the conventional device, it provides superior effects such as remarkable vibration absorption, elimination of passenger's fatigue due to vibration of the vehicle, or the like. Even if the sway of the wheels and engine vibration are transmitted directly to the floor, they are absorbed by the low-pressure pneumatic springs so that the riding quality is remarkably improved. In as much as this invention employs a number of compact low-pressure pneumatic springs, it has superior advantages such as very inexpensive production, simple installation, and long air pressure endurance, and also does not need of complicated maintenance.

In particular, it relates to a stabilizing device on the floor, which is characterized by absorbing and disappearing.
以下本発明の一実施例、 バスで説明する。  Hereinafter, an embodiment of the present invention will be described using a bus.
バ スは、 車体をシ ャ シ フ レ ー ムに架装する所謂フ レ ー ム構造と、 広力外皮構造による一体構造のもの、 所謂フ レ ー ム レ ス モ ノ コ ッ ク 搆造のいずれにおいても、 車室の床は車体側の搆造であり、 車体と 床とは同時振動を受ける。  The bus has a so-called frame structure in which the vehicle body is mounted on the chassis frame, and an integrated structure with a wide-strength skin structure, and a so-called frameless monocoque frame structure. In any case, the floor of the cabin is made of steel on the car body side, and the car body and the floor receive simultaneous vibration.
ところで， 車体に対する緩衝は、 当然のことながら乗客数零時の 無負荷状態から満員時の乗客重量による最大負荷状態を対称に設計 されるが、 バ スの緩衝は、 最近の路線バ スでは板ばね装置を主体と して、 油圧式緩衝器が併用されている。 バ スは周知の如く重量輸送 車であるため、 タ イ ヤ圧は乗用車よ り も高い 7 であり、 車輪反力 の衝撃は前記板ばね装置 よび油 緩衝器併用だけでは効果的に緩 衝し得 い。  By the way, the cushioning for the vehicle body is naturally designed to be symmetrical from the no-load condition when the number of passengers is zero to the maximum load condition due to the full passenger weight when the number of passengers is full. A hydraulic shock absorber is also used mainly with a spring device. As is well known, the bus is a heavy-duty vehicle, so the tire pressure is higher than that of a passenger car7, and the impact of the wheel reaction force can be effectively damped by using only the leaf spring device and the oil shock absorber alone. I get it.

しかし 空気 ί王が高くるることはそれに応じて振動の吸収性は鈍 化し、 圧力的浮上振動が併発する等の難点があり、 また、 車体全体 。 をヱァク ッ シ ョ ンゃ油圧緩衝器によ り緩衝するとィ ニシ ア ル コ ス 卜 が高〈 ¾る難点がある。 However, as the air height increases, the vibration absorption becomes slower, and there are disadvantages such as the occurrence of pressure-induced floating vibration, and the entire vehicle body. There is a drawback that the initial cost is high if the oil is buffered by a working hydraulic shock absorber.
本発明はこれに鑑み、 良好の緩衝性を経済的に得られるよ うにし たバ スを提供するもので、 車体内の床面が全域に、 多数の低圧空気 ばね体を列設し、 それら低圧空気ばね体を一連の給気管に連結し、 車室内の乗客に対して不快 衝撃る振動が及ばるいよ うにした点に 特徴がある。  In view of the above, the present invention provides a bus which can provide good cushioning performance economically, and a number of low-pressure air springs are arranged in a row on the entire floor surface in a vehicle body. A distinctive feature is that a low-pressure air spring is connected to a series of air supply pipes so that passengers in the cabin are subjected to uncomfortable shock vibrations.

第 1図は、 本発明のバスが縦断面図で示されており、 車体 1 の床 面 2上には多数の低圧ばね体 3が列設されている。  FIG. 1 shows a bus of the present invention in a longitudinal sectional view, in which a number of low-pressure springs 3 are arranged in a row on a floor 2 of a vehicle body 1.
上記低圧ばね体 3は、 第 2図に示すよ うに、 二枚の布をゴムに埋 設した 2 プライ ゴム層で成形されたものであって、 その上面は凹凸 面とるっていて、 乗客が滑るのを防ぐよ うになつている。 上記低圧 空気ばね体は好ま しくは高さ 5. 5 、 巾 7 で 0. 5 〜 0. 8 %の空気 圧の空気が供給されている。 上記低圧ばね体 5は、 第 3図に示すよ うに、 床面全域に亘つて配置され、 接する低圧ばね体 5 、 5は給 気管 5によ り互いに連結されている。 そして最端側に位置する低圧 ばね体 5はその列設した低圧ばね体を囲繞するよ うに配設した耠気 配管 5に連結されていて、 その給気管 5には図示しない圧縮装置よ 0. 5 〜 0. 8 の空気圧の空気が供給されるよ うになっている。 ま た上記列設した低 Eばね体 5の上には座席 όが中央通路を挾んで両 側に間隔を置いて配 aされている。  As shown in FIG. 2, the low-pressure spring body 3 is formed of a two-ply rubber layer in which two cloths are embedded in rubber, and the upper surface thereof has an uneven surface, so that passengers can enjoy it. It is designed to prevent slipping. The low-pressure air spring body is preferably 5.5 in height and 7 in width, and is supplied with air at 0.5 to 0.8% air pressure. As shown in FIG. 3, the low-pressure springs 5 are arranged over the entire floor surface, and the low-pressure springs 5, 5 in contact with each other are connected to each other by an air supply pipe 5. The low-pressure spring body 5 located at the extreme end is connected to an air pipe 5 arranged so as to surround the low-pressure spring bodies arranged in a line, and the air supply pipe 5 has a compression device (not shown). Air with an air pressure of 5 to 0.8 is supplied. Further, a seat 体 is arranged on the low E spring body 5 arranged in the above-mentioned manner on both sides of the central passage with a space therebetween.

In addition, passengers will feel as if sitting on a cloud while the bus is running.

'
—方ばね装置 3は車体自重は負荷に加わらず、 乗車可能る人員と、 その手荷物の重量などを対象と して負荷計算すればよいことに ¾る し、 多数に分けることになるので、 1 つの低圧ばね体の負荷は比較 的小さ く てすむから安価に得られる。 . 又、 乗客数が少 い状態での悪路走行において、 車体 1 に大き 衝撃が生じても、 床 2上に設けられた座席には、 ばね装置 5によ り 衝撃が吸収されるため衝撃が直接伝えられ 。  —The spring device 3 does not apply its own weight to the load, but it is sufficient to calculate the load for the occupants and the weight of the baggage. The load on the two low-pressure springs is relatively small and can be obtained at low cost. In addition, when traveling on rough roads with a small number of passengers, even if a large impact occurs on the vehicle body 1, the seat provided on the floor 2 absorbs the impact by the spring device 5, so the impact Is communicated directly.
また本装置を、 列車 . バ ス . 乗用車 . ト ラ ッ ク運転室等に付設す れば振動による疲労障害がな く る等すぐれた効果がある。  If this device is installed in trains, buses, passenger cars, truck cabs, etc., it has an excellent effect such as eliminating fatigue damage due to vibration.

The spring device to be provided with comfort is also very economical because of the use of many small low-pressure spring devices. An object of the present invention is to provide a floor device that contributes to the health of the world and is free from vibration.
