Wheel tread cutting device and wheel tread cutting control method

摘要

PROBLEM TO BE SOLVED: To propose a technique capable of improving a deterioration of riding comfort during idling and sliding by a method other than motor control during straight-line traveling. A wheel tread cutting device 10 is mounted on a railroad vehicle, and cuts the wheel tread based on the rail state of whether or not the top surface of the rail is in a dry state and / or whether or not it is in a wet state. To control. In the wheel tread cutting device 10, the machined portion 110 has a machined portion 111 with respect to a predetermined linear traveling contact portion including a predetermined neutral position as a portion of the wheel tread that comes into contact with the rail during straight traveling. Performs a cutting operation to form a groove by pressing. Further, the semi-wet state detection unit 165 detects that a predetermined semi-wet state condition based on the rail state is satisfied. Then, the cutting control unit 167 causes the machining unit 110 to operate the cutting operation when the acceleration / deceleration detection unit 163 and the semi-wet state detection unit 165 are detected respectively and the groove detection unit 120 is not detected. ..
