The main product of the running gear of railway vehicles that transfer vertical loads from the mass of the locomotive to the rails are wheel pairs. These products are designed to perceive impacts from unevennesses and horizontal forces. The safety of traffic depends on compliance with technical requirements. Correct selection of production technology, materials and wheel formation excludes the risk of an emergency. All requirements are prescribed in the GOST and in the regulations of the customs union. Compliance with standards in the manufacture of wheel sets will help pass the certification, which will allow the sale and operation of the product.
The products for wagons are subject to less stringent requirements. Wheel pairs of locomotives or motor-car rolling stock are subject to high loads, so it is necessary to achieve high strength, reliability and wear resistance of the element. The design of the locomotive wheel pair includes:
On mobile trains pairs with unhindered axles are installed. In this case, some vehicles use disc brakes. Their key feature is the lack of pressing on the axle between the wheels. This is due to the location of the engine in the gap between the wheels.
Locomotive wheel pairs must provide the realization of the power of the locomotive. This requirement is provided by the presence of a gear wheel. It is through it that the torque from the engine or the hydrotransmission is transmitted.
The regulations specify the requirements for installing a bandage for a wheel pair. Over time, the profile wears out around the circle of riding. In this case, turning on a specialized lathe is required. A feature of the process is the work without removing the wheel pair.
“New register” offers services of independent examination of the wheel pair. Qualified specialists of our department within a specified period will perform a full range of tests and provide detailed documentation on the work performed. We accompany clients at all stages of certification, guaranteeing the independence of ongoing research.
