By driving the vehicle on a belt, the load generated when the vehicle actually runs on the road is applied to the vehicle, and the fuel efficiency, power performance, durability test, etc. of the engine according to various driving patterns are performed.
上記の荷重支持装置Ｗは、駆動輪のタイヤ35に加わる
荷重を支え、しかもベルト32の走行を円滑に行う必要が
あり、試験装置の重要な部分であるため、これに適した
種々の装置が提案されている。The above-mentioned load supporting device W needs to support the load applied to the tire 35 of the driving wheel, and furthermore, it is necessary to smoothly run the belt 32. Since this is an important part of the test device, various devices suitable for this are used. Proposed.
一般的には、ベルトとの接触面側に、水を供給して、
この水の動圧又は静圧を利用してベルトの円滑な走行を
行わせる方法が採られている。Generally, water is supplied to the contact surface side with the belt,
A method is adopted in which the belt runs smoothly using the dynamic pressure or static pressure of the water.

この出水口に給水路から水を供給するようにしている。The method based on dynamic pressure is disclosed in Japanese Patent Application Laid-Open No. 56-122986. The outline is that a plurality of long grooves are provided in a direction perpendicular to the running direction of the belt on a surface of the load supporting device facing the belt, and a water outlet is formed in the center of each long groove,
Water is supplied to the water outlet from a water supply channel.

平面のランド部には、水力学的に生起された液膜上の動
圧が生じ、この動圧によりベルトが支えられる。The load of the tire is applied to the load supporting device W via a belt. At this time, when water is supplied from the water supply channel to the water outlet and jetted into the long groove and the belt is run, the dynamic pressure on the liquid film generated hydrodynamically is generated on the land portion of the horizontal plane between the long grooves. This dynamic pressure causes the belt to be supported.
また、ベルトを静圧により支持するものとしては、特
開昭55−128140号公報に開示されている。Japanese Patent Application Laid-Open (JP-A) No. 55-128140 discloses an apparatus for supporting a belt by static pressure.
このものは、上記長溝に代えて多数の円形の出水口を
設けて、この出水口より高圧水を噴出させてベルトを浮
上させて支持する。In this apparatus, a large number of circular water outlets are provided in place of the long grooves, and high-pressure water is ejected from the water outlet to float and support the belt.
D.発明が解決しようとする課題 動圧によるものは、少量の水で足りる利点があるが、

ベルトが傾くと、ベルトの荷重の少ない方の端縁側が浮

て、円滑な支持が損なわれる。D. Problems to be Solved by the Invention Dynamic pressure has the advantage that a small amount of water is sufficient,
After the movement of the belt, the shearing action occurs and the pressure required to support the belt is generated.At the start of the belt start, no dynamic pressure is generated between the belt and the load supporting device. The device is strongly pressed and damaged. In addition, since the long groove is formed by a single groove extending in a direction perpendicular to the running direction of the belt, if the belt is biased due to the bias of the load, the edge of the belt with the smaller load floats, and from there, Water leaks and the pressure supporting the belt decreases, impairing smooth support.
また、静圧によるものは上述の課題はないが水の圧力
でベルトを浮上させ、ベルトと荷重支持装置の間に隙間
を作ってベルトを走行させるので、高圧力の水を大量に
供給する必要があり、水供給設備も大きなものとなり、
また定常時に大量の水を循環させるので、水温の調節に
も大きな設備を必要とする。In addition, the static pressure does not have the above-mentioned problems, but the belt floats with the pressure of water, and a gap is created between the belt and the load supporting device to run the belt. And the water supply facilities are also large,
In addition, since a large amount of water is circulated in a steady state, a large facility is required for adjusting the water temperature.
更に、供給される水が高圧であるため、荷重支持装置
の外部に水が飛散するので、これを防止する完全なシー
ル機構を備える必要がある。Further, since the supplied water is at a high pressure, the water scatters outside the load supporting device, and it is necessary to provide a complete sealing mechanism for preventing the water from scattering.

On the opposite surface, water outlets 2 each having a flat rectangular shape are arranged in columns and rows at arbitrary intervals, and the water outlets 2 are recessed in the belt running direction indicated by the arrow X as shown in FIG. 4 (B). The applicant of the present invention has proposed a configuration in which an arc-shaped pocket portion P is formed and communicates with a water supply passage 4 and a water supply hole 14 as shown in FIG. 4 (C) so that both dynamic pressure and static pressure can be used. .

複雑なものとなる等の課題が残されていた。However, when actually used, the load is not applied to the belt on all the water outlets, but is applied only to the portion where the tire 35 is mounted as shown in FIG. The hydraulic pressure required to support the load only needs to be given to the water outlet 2a in the part where the water flows, and the other water outlets 2b and 2c
May be provided by supplying a small amount of liquid necessary for forming a liquid film. However, the one shown in FIG. 4 supplies a liquid necessary to support the load to all the water outlets, so that a large amount of liquid is required, and the pump for supplying the liquid is accordingly enlarged, and the power consumption is also large. As the amount of liquid used increases and the amount of liquid used further increases, the amount of liquid scattered around increases, and the sealing mechanism for preventing drainage and leakage becomes complicated. Challenges remained.
そこで、本発明は、供給液体量を大巾に減少させて、
上記の課題の解決を図ることを目的とする。Therefore, the present invention significantly reduces the supply liquid amount,
An object of the present invention is to solve the above problems.

An endless belt that runs stretched between two rotating drums,
A support member for supporting the load applied to the upper surface of the endless belt between the two rotating drums on the lower surface of the endless belt, and a plurality of water outlets provided on the surface of the belt facing surface of the support member;
In a load supporting device provided with the water outlet and a water supply passage for supplying liquid to the water outlet through the communication hole, a nozzle having a water supply hole at the center of the communication hole is movably penetrated, and an outer periphery of the nozzle is provided. Forming a water passage that connects the water supply passage and the water outlet outside the communication, and forming a valve in the water supply passage that opens and closes by moving a nozzle, and opens the valve when the nozzle is pressed by the belt to open the water passage; The liquid is supplied from the water supply passage to the water outlet through the water supply passage.

を支持するに必要な液体が供給される。F. Action When a load such as a tire is applied to the belt, the nozzle at the water outlet located at the back of the belt at the portion supporting the load is pushed down by the belt. When the nozzle moves downward, the valve opens, and the liquid in the water supply passage flows out of the water outlet through the water passage on the outer periphery of the nozzle from the water supply passage, and the liquid necessary to support the load is supplied.

すればよいので、供給液体の量は少なくて済む。On the other hand, the nozzle at the outlet of the portion where no load is applied is not pressed and the valve is kept closed, so that a small amount of liquid is supplied from the water supply hole through the central throttle hole. Therefore, the necessary liquid needs to be supplied only to the water outlet of the portion supporting the load, so that the amount of the supplied liquid can be small.

に螺合されている。FIG. 1 shows a sectional view of one of the outlets,
(A) shows a state where the valve is open, and (B) shows a state where it is closed. In these figures, reference numeral 1 denotes a support member, on which a water outlet 2 as shown in FIG.
The communication hole 3 which communicates with the hole is formed. 5 is a nozzle,
The nozzle 5 has a head 6 having a diameter smaller than the width of the water outlet 2 and a diameter larger than the communication hole 3, a cylindrical portion 7 penetrating the communication hole 3, and a water supply penetrating the center of the head 6 and the cylindrical portion 7. Holes 14 and screw portions 8, 9 screwed to the outer periphery of the lower end portion of cylinder portion 7 opposite to head portion 6
And a water passage 10 formed of a spiral groove screwed around the outer periphery of the cylindrical portion 7. V is a valve, which is formed by a valve member 11 screwed into a screw portion 9 in the water supply passage 4 at the lower end of the nozzle 5. In this valve V, when the upper surface of the nozzle 5 is flush with the upper surface of the support member 1, a gap h is formed in the valve V as shown in FIG. It is communicated via the waterway 10. When the nozzle 5 moves upward, the valve V is closed as shown in FIG. 1 (B), and the head surface of the nozzle 5 protrudes from the surface of the support member 1 by the wrist h '.
Reference numeral 12 denotes an aperture member, which is provided with an aperture 13 in the center,

When water is supplied to the water supply passage 4 as shown in FIG.
Valve V is a hydraulic (or spring) as shown in FIG.
Then, the valve V is closed and the valve V is closed, and a small amount of water flows out of the tip of the nozzle 5 through the throttle hole 13 and the water supply hole 14 to form a water film on the entire surface of the support member 1. In this state, when the tire is placed on the belt and a load is applied to the belt, the belt in the portion where the load is applied is pressed by the support member 1 as shown in FIG. The nozzle 5 is pushed down to the surface position of the support member 1 as shown in FIG. Therefore, the gap h between the valve member 11 and the support member 1
The water in the water supply passage 4 flows out of the gap through the water passage 10 and also from the water outlet 2 to support the load on the belt. The nozzles 5 of the water outlets 2b and 2c in the portions that do not support the load allow a small amount of water to flow out only from the water supply hole 14 while keeping the state of FIG. 1 (B). Therefore, since it is not necessary to supply water necessary to support the belt to all the water outlets of the load supporting member, the amount of water supplied from the water supply passage 4 is greatly reduced.
