本発明は、リング状の防振ゴムを用いた鉄道車両の軸箱
支持装績に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an axle box support system for a railway vehicle using a ring-shaped anti-vibration rubber.

配醒された心金11および該外筒7と心金11との間に
配属されローリングゴム9とから成っている。Conventionally, an axle box support device a using a ring-shaped anti-vibration rubber (hereinafter referred to as a rolling rubber spring) has a structure shown in Figs. 1 and 3. In the figure, l is the vehicle body and 3 is a pillow. A bogie 4 supports the vehicle body l via a spring 2, and a rolling rubber spring 4 supports and fixes an axle box body 5 provided at both ends of a wheel axle 6 and supports the bogie 3. The rolling rubber spring 4
As shown in FIG. 3, it consists of a bell-shaped outer cylinder 7, a mandrel 11 which is concentrically bent, and a rolling rubber 9 disposed between the outer cylinder 7 and the mandrel 11. .

ては別にオイルダンパーなどを追加する必要があるとい
う欠点があった。By the way, in the above structure, since the outer cylinder 7 and the rolling rubber 9 and the core metal 11 and the rolling rubber 9 are in direct contact with each other, they are extremely hard to slip (the spring characteristics are dominated by the characteristics of pure rubber). There was a tendency.As a general characteristic of rubber, the higher the frequency, the harder the rubber becomes equivalently, and the dynamic spring constant tends to increase.This ratio is called the dynamic magnification (Ko/Ks). Figure 2 shows the relationship between frequency and dynamic magnification.In other words, rubber with large internal damping exhibits characteristics like C.In this case, when trying to obtain sufficient damping force in the low frequency range, Although it is suitable, the spring constant increases in the high frequency range, resulting in a rough ride.Rubber with low internal damping exhibits characteristics like B, and the spring constant increases in the high frequency range. Since there is little, the lumpy problem is solved, but this time, the attenuation in the low frequency range results in electrical failure, and in some cases, there is a disadvantage that it is necessary to add a separate oil damper.
上記の点に鑑み本発明は、低周波域で十分な減衰力を与
えながら、かつ、高周波域で動倍率が上昇せず、ゴツゴ
ツ音が伝わりにくい、乗心地の良いばね装Wを提供する
ことを目的としたものである。In view of the above points, it is an object of the present invention to provide a spring mounting W with good ride comfort, which provides sufficient damping force in the low frequency range, does not increase dynamic magnification in the high frequency range, and does not transmit rough sounds easily. The purpose is to

図ることを特徴とするものである・ 。The present invention adjusts the coefficient of friction between the rolling rubber, outer cylinder, and core metal by applying a coating material, etc., and actively provides slippage, thereby providing a high coefficient of friction in the low frequency range and increasing the damping force. At the same time, in the high frequency range, the coefficient is lowered to reduce dynamic magnification and improve riding comfort.

FIG. 3 is a sectional view showing an example of a rolling rubber spring of FIG.

たがって、低周波域では滑り速度が小さいため、摩擦力

。In the figure, the same reference numerals as those in the conventional example shown in 1tff indicate the same members, and their explanation will be omitted here. 8 is a coachive material applied to the inner surface of the outer cylinder 7, lO is a coachive material applied to the outer peripheral surface of the mandrel 11, and the coachive material 8 and lO actively prevent slippage between them and the rolling rubber 9. Choose a material that has a role to play and is compatible with this role. Therefore, in the low frequency range, the sliding speed is small, so the friction force is large h<the damping force is large h<, and in the high frequency range, the sliding speed is high, so the frictional force is small and the damping force is small, resulting in a dynamic magnification. It fosters friction properties that reduce friction.
このような構成によれば、周波数と動倍率の関係が第2

る。According to such a configuration, the relationship between the frequency and the dynamic magnification is the second
It forms a curve like A in the equation above, and gives large damping at 1 to 2 Hz, and lowers the dynamic magnification around 8 to 10 Hz, which corresponds to rough vibrations such as chattering vibrations of the car body, making it difficult for rough vibrations to be transmitted. Therefore, it is possible to obtain a spring arrangement that provides sufficient damping, does not transmit rough vibrations to the vehicle body, and provides a comfortable ride.

ごつした振動が伝わりに((なる。The explanation will be omitted here. 9' is a rolling rubber whose surface is coated with a coating material 12. Note that no coating material or the like is applied to the contact surfaces of the outer cylinder 7 and the core metal 11 with the rolling rubber q.In such a configuration, the characteristics against vibration are the same as those in the above-mentioned embodiment, and the rough vibration is Legend has it ((Naru).
このような構成働こよれば、II前記一実施例に比べて

3, the work time and man-hours can be reduced compared to the case where the inner surface of the outer cylinder 7 and the outer circumferential surface of the mandrel 11 are coated.

Since the dynamic magnification is reduced, it is possible to improve the first ride comfort, which is caused by rough vibrations and chatter vibrations.
