FIELD: railway transport, measurement of width of gauge directly under rolling stock (locomotive, railway motor car, etc), study of kinematic interaction of rolling stock and track in horizontal plane. SUBSTANCE: increased accuracy of measurement is achieved as gear determining position of wheel pair in railway gauge and width of gauge is composed of rigid frame carrying three capacitive contactless converters as minimum attached to body of traction electric motor or axial reduction gear of rolling stock, capacitive plates of contactless converters are arranged at angle with regard to vertical axis of rail and are placed into diode-capacitor bridges which are connected to computer via amplifiers. Two plates of capacitive contactless converter are arranged at angle from 25 to 45 deg. EFFECT: increased accuracy of measurement by prevention of influence on key measurement signals of noises from acceleration of wheel pairs in boxes, from vertical movements of capacitive plates, from nonlinearity of signal. |
