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 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.

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.

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.

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.

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.
