Spring offset axis of the probe 7 has the ability and the second end of the pair of wheels.

From the side facing the wheel pair, the lever 6 is spring-loaded helical spring 9, which is located and secured to the beam 4 by means of a pin 10. At the ends of the axes 2, on the reverse side relative to the roller 1 is fixed bracket 11 with a horizontal shelf 12 with the hole 13 and the screw 14 for installation and fastening of the Registrar of defects on the surface 15 made in the form of a dial indicator ICH-10. Opposite the spherical thrust bearing 8 spring two shoulders of the lever 6 is the rod 16. At a 90° angle to the generatrix of the two shoulders of the lever 6 is attached Registrar diameter wheels, made in the form of a flat element 17 arrow 18 and a linear scale 19, secured to the bracket 11. Linear scale 19 has the shape of part of a circle, the radius of which is identical with the radius of movement of a spring-loaded two shoulders of the lever 6 about its axis 5. The bracket 11 is attached a spring-loaded bracket 20 by screws 21, the guide sleeve 22, a spring 23, a guiding element 24, which interacts with the guide sleeve 22. Strip of 3 mounted and fixed hollow element with a groove 25 with linear divisions to Registrar of wear ridges, which is a rod 26 with a mark of 27. The rod 26 audinece axis of the probe 28, you can measure defects on the ridge along its generatrix from the base of the ridge to its summit.

The carriage 29 is formed by rollers 1 and axis 2, interconnected by a strap 3.

Sensitive elements made in the form of probes 7 and 28, connected with the carriage 29 and through the respective signal converters - Registrar respectively of wear ridges and imperfections on the surface.

Is based devices rollers 1 on the rolling surface of the pair of wheels on the same surface, but between the rollers 1 set the sensing element with an offset axis 7 of the signal Converter 6. The sensing element 7 by a spring 9 mounted on the beam 4 by the pin 10, is pressed against the surface of Coles the sending element 24, after that move at low speed wheelset along with rail rolling stock, with rolled rollers 1 wheelset wheelset, and the sensing element with an offset axis 7 of the signal Converter 6 receives the opportunity due to its offset axis to be located at any point on the tread surface of the wheel pairs, starting from the base of the crest wheelset to its end facet by reversal of the sensing element 7 with respect to its main axis to the desired angle.

The measurement result of defects of the wheelset wheelset is read by the variance of the arrow Registrar defects of the surface 15, which is installed in the hole 13 and is fixed by a screw 14 on the horizontal shelf 12 that is installed and fixed to the bracket 11. Intermediate components involved in the measurement are spherical thrust bearing 8 signal Converter 6 that is in contact with the rod 16 Registrar defects on the surface 15 of the beam 4 that is installed and fixed on the carriage 29, the axis 5 about which moved two equal along the length of the shoulder of the signal Converter 6.

All of these listed items are involved in the measurements. With their pomology influx of metal;

ring generation;

- thin rim;

- the slider (flat position);

- nawar (offset metal on the surface of the wheel rim);

- fishermen (spalling surface area of Catania);

- the surface of the slit at the outer edge of the rim;

the slit circular influx;

- single transverse cracks;

- longitudinal cracks distances and nonmetallic inclusions;

- grid thermal cracks in the rim.

To measure the wear ridge at spring and shifted the axis of the sensing element 28 of the rod 26 to rotate it to the end portion of the offset axis, resulting in the sensing element 28 in the form of a rod under the action of its spring 23 is in contact with the comb in place. This ability of the sensing element 28 generates a control comb, starting from its base to its top. The probe 28 when this affects the signal Converter, made in the form of a rod 26 with a mark 27, through which the line divisions in the hollow element with a groove 25 (Registrar of wear ridges) is the measurement result.

The above steps create the ability to control these defects at the crest wheelset:

- thin ridge (the thickness of the ridge is less valid is the pair of the cutting part of the ridge with the top).

Next stop the movement of the pair of wheels with rail rolling stock and measure the diameter of the pair of wheels that were previously mounted on a linear scale 19 Registrar diameter wheels a grade of “0” corresponding to the new wheel pair, and when measuring the diameter of the worn wheel pair due to the displacement axis of the sensing element 7 to the signal Converter 6 is moved down, pulling the sensitive element (probe) 7 to contact with the surface of the pair of wheels, turning at the same time around its axis 5. As a result, the second shoulder of the signal Converter 6 together with a spherical thrust bearing 8 and the Registrar of the wheel diameter, made in the form of a flat element 17 arrow 18 and the linear scale 19, rotated about the axis 5 and rises at the same angle as when lowering the sensing element 7 to the wheelset wheelset. At this time the arrow 18 Registrar diameter wheel will indicate its linear scale 19 the mark corresponding to the diameter of the wheel pair.

The use of this device in rail rolling stock eliminates the possibility of gathering it from the track and the ability to create emergency situations associated with loss of life.

So who ensure the safety of railway rolling stock by improving device reliability and extend its functionality.
