METHOD OF DETERMINATION OF CLEARANCE BETWEEN RIDGE OF RAILWAY WHEEL AND RAIL HEAD AND DEVICE TO EFFECT DETERMINATION Russian patent published in 2008 - IPC B61K9/12 E01B35/12 

FIELD: transportation.

SUBSTANCE: invention relates to the equipment for measuring railway rails and wheels. The method of determination of the clearance between the railway wheel ridge (2) and rail head (1) includes attaching a pickup with its sensitive element directed towards the point of contact between the wheel and rail head to a crosswise beam (3) of the car truck. Simultaneously with the start of the car, the data coming the pickup on displacement of the wheel ridge relative to the rail head at a preset distance is continuously recorded. Then the pickup is removed from the car, the data carrier is removed from the pickup and the data obtained is processed using a computer programme to provided for a digital visual picture. On the picture thus obtained, a video image of a ruler with divisions is imposed to define the abode said clearance in divisions of the ruler. The said device has a case with a core, a pickup and light sources arranged on both sides of the pickup at an equal distance from it.

EFFECT: simpler design and smaller sizes of the device.
