A device for measuring Bicycle wheels of railway vehicles made in the form of a movable in the horizontal plane of the carriage 1, is equipped with a vertical axis 2 with the roller 3, which is designed to interact with nathusii wheel, pushing the carriage 1 to the inside of the track. Between the end portions of the rails 4 and 5 is rigidly fixed to the base 6 attached to the soles of the mentioned rails, provided with a notch 7 for placement and movement of the carriage 1. In order that the carriage 1 can move only in the horizontal plane, the neck 7 has the shape of a swallow's tail" (see Fig. 3). To return the carriage 1 to the initial position provided by the spring 8. In the carriage 1 has a cylindrical cavity for placement of the sensing elements in the form of spring-loaded probes 9 and C-scale amplifiers 15 and 16 are connected to respective inputs of the recorder 17. The probe 9 is designed to measure the amount of rent, and the probe 10 to determine when the measurement on the tape recording device 17, which is the recording of both signals. The distance "a" depends on the type of the measured wheel and it is therefore necessary to have a set of carriages 1 for each type of wheels of the fleet of locomotives and wagons. The roller 3 can communicate with the Central part of the bandage.

Before using the device, check the mutual position of the pointed heads of the rods 9 and 10 to a reference sample, is designed as a portable sector bandage wheels, and record the marker pens of the recorder on the tape recorder 17. If necessary, the head of the probes 9 and 10 is screwed into the cylindrical body of the probe, or Vice versa vivencial of them, then) these heads in a position corresponding to the zero rent. Then let the vehicle through the device and measure his car wheels on both sides of the path, which provides two carriage 1, installed in the crevices of both lines of rails with some shift to measure Bicycle wheel wheelset was carried out sequentially one after the other hand, although different carriages, but OBV with the carriage, under the influence of the wheel.

The wheel 18 during its movement along the rail 4 comes into contact with the roller 3 with its rounded crest 19 that leads to the displacement of the carriage 1 to the right, i.e., inside the track in the measuring position in which the roller 3 communicates with the vertical surface 20 of the drive wheel 18, by setting the carriage 1 so that the head of the probe 10 has been in contact with the ridge 19 on the distance "b" from the vertical plane 20, and the head of the probe 9 at a distance "a" in contact with the rolling surface of the wheel 18.

Move the probes 9 and 10 under the influence of the wheel 18 in a vertical plane will be transformed by the elements 14 and 13 control movement into the corresponding electrical signals which are amplified large-scale amplifiers 15 and 16 and then fed to the corresponding inputs of the recorder 17, the control feathers recorder.

The device provides high quality measurements of Bicycle wheels vehicles without stopping on the last position control, which allows you to shorten the scan time and location of a moving object in the repair. The test results of each pair of wheels fixed on the tape recorder and can serve as documentary podtverzhdeniya.neskolko vehicles contains the set of the rails in the passage area of the wheel sensors to interact with the side surfaces of the wheels and their crests and the sensing element to start the measurement, the last two of which through the respective signal transducers associated with the Registrar, characterized in that it is provided with a sensitive element for engagement with the rolling surface of the wheels, the latter and the sensing element for interaction with a crest wheels made in the form of probes, and installed between the ends of two adjacent rails of the movable and spring-loaded in a horizontal plane, a carriage having a base in the form of a dovetail, posted in made in rigidly attached to the sole plate rails guide groove similar to the base form, the longitudinal axis of which is perpendicular to the longitudinal axis of the rails, whereby the carriage is made with two vertical cylindrical cavities have mentioned probes, which is spring-loaded in a vertical plane, and the signal transducers made in the form of associated thrust through with probes controls movement, and the Registrar - recorder.
