によつて正確かつ容易に可能にした新しいタイヤ
試験機の提供に関する。Detailed Description of the Invention (Field of Industrial Application) The present invention relates to a tire testing machine, and more specifically, it uses a drive source with extremely low output to test driving and braking under the same conditions as an actual vehicle. (motor)
The present invention relates to the provision of a new tire testing machine that is accurate and easy to use.

動力を与えてタイヤ特性試験とブレーキ試験とを
行なうものである。(Prior art) A tire testing machine that drives both a tire and a substitute road surface (steel wheel) is disclosed, for example, in Japanese Patent Publication No. 1981-9881. The surface speed of the steel wheel and the surface speed of the tire are actively set to be different, and the driving force and braking force seen from the tire is transmitted between the tire and the steel wheel. tire characteristics tests and brake tests.
（発明が解決しようとする問題点）
この従来技術においてはタイヤ側及び鋼製ホイ
ール側の双方に駆動、制動の機能をもつた駆動源
を設ける必要があり、又、駆動力及び制動力を充
分に発生させるために相当大きな出力の駆動源
（原動機）を設ける必要があつた。(Problems to be Solved by the Invention) In this prior art, it is necessary to provide a drive source with driving and braking functions on both the tire side and the steel wheel side, and it is necessary to provide a drive source with driving and braking functions on both the tire side and the steel wheel side. In order to generate this power, it was necessary to provide a drive source (prime mover) with a considerably large output.
即ち、原動機として駆動及び制動の双方が容易
に得ることができる油圧ポンプ・モータを使用し
ているのであり、この場合、例えば時速50Kmで走
行している直径1mのタイヤに200Kg・ｍの駆動ト

に必要な動力は、
ＱT＝１／９７４（５０Km／ｈ×１０００ｍ／Km／６
０ｍｉｎ／ｈ
×１／１ｍ×３．１４×200Kg・ｍ）＝54.5Kw
となり、回転部の機械損失やタイヤの転がり抵抗
を無視した理論値として約55KW相当の出力を有
する油圧ポンプモータが必要となる。 In other words, a hydraulic pump/motor is used as the prime mover, which can easily provide both driving and braking functions. (The driving force on the tire surface is 400Kg) is: Q T = 1/974 (50Km/h x 1000m/Km/6)
0min/h x 1/1m x 3.14 x 200Kg・m) = 54.5Kw, and a hydraulic pump motor with an output equivalent to approximately 55KW is required as a theoretical value ignoring mechanical loss in rotating parts and rolling resistance of tires. Become.
又、鋼製ホイール側においても当然前述と同等

動作させなければならないが、油圧ポンプモータ
が吐出した油圧を流量制御弁やリリーフ弁などで
制御することから加わつた動力はほとんど熱とし
て放散してしまう結果となる。 Also, on the steel wheel side, of course, the same power as mentioned above is transmitted from the tire, so the hydraulic pump motor on the steel wheel side must be operated to apply braking force, but the hydraulic pump motor discharges Most of the power applied because hydraulic pressure is controlled by flow control valves, relief valves, etc. is dissipated as heat.

ーに反し、設備的に高価となること等から現実性
にかけるものであつた。 Therefore, when installing a motor that generates driving braking force on both the tire side and the steel wheel side,
A prime mover with an output of 55KW or more was required, which was difficult to implement in practice, in other words, it was not practical because it was energy-saving and the equipment was expensive.
更に、タイヤはその種類形状によつてサイズが
異なつても正確にして確実な回転動力を伝達しな
ければならないにも拘らず、この点についての配
慮がなされていないものであつた。 Further, although tires must transmit rotational power accurately and reliably even though they vary in size depending on their type and shape, no consideration has been given to this point.

今一歩であつた。 Although it is not a tire testing device, technology for saving energy by circulating power in a testing device has been proposed, for example, in Japanese Patent Publication No. 49-36431.
It was still a step before it could be applied to objects with a wide variety of types and shapes.

に必要でなくなる。(Effects of the Invention) According to the present invention, the tire mounted on the tire support is pressed into contact with the substitute road surface body that is rotated or rotated by the drive source, so that the tire is driven to rotate by the rotation of the substitute road surface body. This eliminates the need for separate drive sources, such as those that rotate the substitute road surface and tires independently.

伝動することができる。 Furthermore, since the rotary transmission shaft system on the tire support side has a freely bendable joint shaft that can be freely expanded and contracted in the axial direction, the size of the tire that is detachably attached to the tire support can be changed in size. In either case, the tire support can be smoothly moved near and far with little resistance with respect to the substitute road surface, and the tire support, that is, the tire, can be accurately and smoothly rotated and transmitted to the transmission.

ここに、全体をコンパクトにしながらの正確、円
滑な試験ができる。 In other words, it is possible to connect the shaft end of the universal joint shaft to the tire support side on the side closer to the substitute road surface body side, but according to this, unless the distance between the shafts of each rotary transmission shaft system is large, the size will be large. However, in the present invention, the shaft end of the universal joint shaft on the tire support side is located on the far side from the substitute road surface body, so that it is difficult to change gears. Even if the distance between the shafts of the rotary transmission shaft system on the machine side is reduced and they are set parallel to each other, tires of different sizes can be mounted on the support.
This allows for accurate and smooth testing while keeping the entire device compact.

In this step, rotary transmission shaft systems are provided on each of the output sides of the substitute road surface body side and the tire support side, with their axes parallel to each other, and transmissions each driven by the rotary transmission shaft systems are interposed between the shaft systems. The rotary transmission shaft system on the tire support side has a universal joint shaft that can be freely bent and axially expanded and contracted, and the shaft end of the universal joint shaft on the tire support side is A tire testing machine characterized by being connected to an output shaft on a tire support side on a side farther from a substitute road surface body side.
