である。In a railway vehicle, a driving force or a braking force generated on the vehicle side is transmitted to the rail side by a frictional force between the rail and wheels. FIG. 3 is a view showing an adhesive device for a high-speed railway vehicle, in which 1 is an air reservoir, 2 is an air pipe,

Hereinafter, this operation will be described. For example, compressed air stored in the air reservoir (1) is sent to an air cylinder (4) through an air pipe (2) and an open air passage in a solenoid valve by a brake signal and a slip signal or a sliding signal. As a result, the abrasion element (6) is pressed against the wheel tread and removes the adhesion of the wheel tread which reduces the adhesive force, and increases the adhesive force by making the wheel tread an appropriate roughness.

ない。FIG. 2 is a block diagram illustrating the operation of the conventional thickening device for high-speed railway vehicles. In FIG. 2, a grinding wheel control signal is output when a slip signal or a sliding signal is input to the control unit (flow F1), or when a slip signal or a sliding signal is not input to the control unit (flow F1), a brake signal is output. When the signal is input to the control section (flow F2), the control section outputs the signal to drive the solenoid valve (3) in synchronization with these signals (flow F3). Then, the solenoid valve (3) is driven by the grinding wheel control signal, the air cylinder (4) is operated by the air from the air reservoir (1), and the grinding wheel (6) is pressed against the wheel tread surface, and the wheel tread surface is rotated. The process of increasing tackiness is performed. In addition, no slip signal or run signal is input (flow F1)
When the brake signal is not input (flow F2), the control unit does not output the grinding wheel operation signal, and the process of increasing the tackiness of the wheel tread is not performed. Further, when the slip signal or the sliding signal is included in the brake signal, the operation signal of the grinding wheel is continuously output even if the brake signal is turned off (flow F3). However, the operation of the grinding wheel follows the brake signal, the slip signal, or the sliding signal regardless of the adhesion state between the rail and the wheel, that is, regardless of the amount of adhesion. For this reason,
Although the operation of the grinding wheel is unnecessary in fine weather, the grinding wheel is always pressed against the wheel tread surface while the brake signal is input, and the wheel material should be a material with a high adhesion effect from the viewpoint of wear resistance. And the effect of increasing tackiness is small.

化している。The adhesion increasing device of the railway vehicle is configured as described above, and the operation of the abrasive is controlled according to the presence or absence of the input of the brake signal, the slip signal, or the sliding signal regardless of the amount of the adhesive force. However, the adhesive force between the rail and the wheels is not always insufficient, but changes due to natural conditions on the rail.

うことができることから高速鉄道車両用増粘着装置を提
供することを目的とする。In such a situation, the increase in the amount of abrasion of the railroad vehicle increases because the grinder is constantly pressed against the wheel tread while the brake signal is being input, regardless of the amount of adhesion between the rail wheels. For this reason, there is a problem that the material of the wheel cannot be made a material having a high adhesion effect. In addition, since the wear of the grinding element progresses, it takes time and effort to maintain the grinding element. At the same time, the wheel tread surface is abnormally worn, so that the shape of the wheel tread surface is deformed. Further, there is a disadvantage that it is not possible to improve the adhesive strength during power running. The present invention has been made to solve the above-described problems, and detects an adhesion state between a rail and a wheel tread surface, operates a grinder only in a low adhesion state, and increases the material of a wheel. It is an object of the present invention to provide an increased adhesion device for high-speed railway vehicles because a material having a high adhesion effect can be used.

走ばかりでなく空転も防止するものである。The high adhesion device for high-speed railway vehicles according to the present invention, when a rain signal is input, when the adhesion between the rail and the wheel tread is detected as a low adhesion state, when the vehicle is in a running state, the grinding wheel Is activated by making the wheel tread rough by intermittently operating. Then, the adhesion between the rail and the wheel tread is increased due to the remaining effect of the wheel tread activated when the next brake signal is input. Further, as in the prior art, the grinder is operated when a brake signal or a sliding signal is input, and the grinder is operated also during a powering signal, thereby preventing not only running but also slipping.

る。When there is no rain signal, the grinder is operated only when a gliding or slip signal is input. If there is a rainfall signal but no brake signal or powering signal, the grinding wheel is operated intermittently, and due to the remaining effect of activation of the wheel tread, an increase in sticking effect at the next brake signal input is expected. When the brake signal or the powering signal is input together with the rainfall signal, the grinding element is continuously operated as in the related art.

A powering sensor for detecting, a wheel sliding state of the vehicle and a sliding / idling sensor for detecting an idling state of the wheel of the vehicle, and a solenoid valve (3) for pressing the abrasive (6) shown in FIG. 3 against the wheel tread surface are driven. It has a drive unit and a control unit that controls the drive unit based on a detection signal of each of the sensors described above. The control unit outputs a continuous control signal for continuously controlling the solenoid valve (3) or an intermittent control signal for controlling the solenoid valve (3) intermittently to the drive unit according to the input detection signal.

な加減速度が確保できるという効果を有する。As described above, the present invention improves a low-adhesion state due to rainfall by adding a rainfall signal to the operation circuit of the polishing element. Also, by operating the polishing element during power running, adhesion during power running is improved, and frequent occurrence of sliding and idling is suppressed. This means that by operating the grinder only during rainfall, it is possible to use a material with a high sticking effect even if the amount of wear increases somewhat, while improving maintenance problems due to wear of the grinder and reducing vehicle movement. This has the effect of preventing abrasion of the wheel tread, which is a problem. These have the effect that safe and reliable acceleration / deceleration can be ensured.
