れらは、いずれも動力源が必要であり・１嫡構も、複雑
で価格的にも、コスト高になる欠点があった。Conventional rubber lowering devices for rubber retarders include those that combine a retarder and a cam or roller, and those that combine a hydraulic cylinder and a cam roller. All of these require a power source and have the disadvantage of being complicated and expensive.

のｉｊ制御方式を提供するにある。The purpose of the present invention is to apply or release a restraining force to a freight car passing over a rubber retarder by using only the suction action of liquid without using a motive or a power source such as a hydraulic pump. An object of the present invention is to provide an inexpensive and highly reliable ij control method for a rubber retarder.

ようにしたものである。The present invention uses hydraulic pressure, which allows liquid to be sealed in the lower part of an elastic body such as rubber, as a means for applying, breaking, or releasing a braking effect on a freight car passing over a rubber retarder. The wagon is controlled by changing the mounting position of the elastic body.

Numeral 5 is made of rubber and is installed on sleepers 3 through rubber supports 4 in some sections of the rail 3, and the rubber 5 is compressed by the wheels 1 of the freight car to provide a braking action.

FIG. 3 is a sectional view taken along the line AA in FIG. 2, and 8 is a piston that is slidably held within the cylinder 6. A return spring 7 pushes the rubber 5 upward via the piston 8 and the rubber pedestal 4. 9 is an O-ring provided to prevent oil leakage from the cylinder 6. In addition, an electric valve 2 is provided between the tank 14 and the cylinder 6.

る。Next, the operating principle of the present invention will be explained. FIG. 3 shows the operation of the rubber retarder, in which oil 3 is sucked into the cylinder 6, and by closing the port of the direct magnetic valve 12, the oil 3 is sealed inside the cylinder. Therefore, the piston 8 is kept in the raised state, and the two parts of the rubber 5 are transferred to the wheels 1 of the freight car, thereby exerting a braking action. If the freight car does not require a braking action, the port 1 of the solenoid valve 12 is opened, as shown in FIG. 4, so that the oil 13 can freely flow between the cylinder 6 and the tank 14. It's like that.

め、ゴムリターダとしての制動力は作用しない。Therefore, when the freight car enters, the piston 8 is
, the oil 13 in the cylinder 6 flows into the tank 14, the rubber 5 descends, and the wagon wheels 1 transfer to the guide rail. Therefore, since the rubber 5 is not pressurized, no braking force acts as a rubber retarder.

リンダ６内に吸込捷れる。When the wheels of the freight car pass, the piston 8 is buried by the return spring 7 and the inside of the cylinder 6 becomes a vacuum state, so the oil 13 in the tank 14 is sucked into the cylinder 6 through the solenoid valve 12. I can break it.
この実施例によれば、電磁弁１２の利Ａｌのみで、ゴム
リターダの制動・解放制御を行うことができる。According to this embodiment, braking and releasing control of the rubber retarder can be performed using only the aluminum of the solenoid valve 12.
