Certification in accordance with Customs Union Technical Regulations

Wheelsets wagon

The key element of the running gear of the railway transport are wheel pairs. These products can be manufactured in a certain design, size and shape. However, the manufacture must be carried out in accordance with the requirements of GOST and the regulations of the customs union. Since the element is subjected to high loads, it is necessary to ensure high strength and wear resistance of products. To achieve efficient production allows the addition of carbon to the wheel pair. However, the strength of the material is not the only requirement.

What is considered for certification?

The inspection of wheel sets is based on the safety of operation and the conformity of the product to the established parameters. Since the railway tracks are strictly in accordance with the customs union, the undercarriage of any vehicle must be based on an operating document. All wheel pairs are divided according to the type of wagons they are installed on:

Freight. These products must withstand a load of 230.5 kN, and maintain performance at a speed of 120 km / h. The tests carried out are primarily based on the preservation of the properties and characteristics of these parameters during the movement.

Passenger. Such wheel pairs undergo the least load (about 176.6 kN). However, the compositions move at a speed of up to 160 km / h, which implies high wear and tear.

Non-motor diesel or electric trains. The design speed is 130 km / h, the maximum load is 186 kN. Wheel pairs here undergo medium loads, so they must combine features of other products.

The most important parameters of the wheel pair are the structure of the axis, the material of manufacture and the diameter of the articles. These features directly affect the quality of the wheel, as well as its functionality while driving.

Today, most wheel pairs are divided into one-piece, bandage, elastic, sliding and rotating on the axle. Depending on the design features, the certification of products is different.
