Wheels and axles are the most important parts of a train, literally supporting the safety of railway rolling stock under the floor.
We mainly produce three types of train wheels: wagon wheels, Passenger Car Wheels and Locomotive Wheels.
Train Wheels Manufacturing Process:
Billet review → cutting → heating → forging → heat treatment → sampling test → rough machining → semi-finishing → finishing → hardness test → static unbalance test → ultrasonic inspection → magnetic particle inspection → packaging
Types of Train Wheels
1. Wagon train wheel
Used for railway freight car bogies, running speed up to 120km/h, wheel load. Truck wheels usually use tread brakes.
There are usually two types of manufacturing, casting and rolling. Use basin wheel webs when casting. For rolling, the web is usually S-shaped.
The wheels are manufactured in accordance with TB/T 2817, AAR M-107/208, BS 5892-3 and EN 13262 standards.
2. Passenger car train wheel
For railway passenger car bogies, the wheel running speed is about 120km/h or more, and the wheel load is light.
They usually use shaft disc brakes or wheel disc brakes.
Passenger car wheels are manufactured by rolling. According to different braking methods, the webs can be S-shaped, double S-shaped or straight.
In the manufacturing process, it complies with manufacturing standards TB/T 2817/2708, AAR M-107, BS 5892-3 and EN 13262.
3. Locomotive and train wheels
There are two types of locomotive wheels: integral wheels and split wheels.
The diameter of locomotive wheels is larger than that of ordinary wheels, usually over 1000mm.
Comply with manufacturing standards TB/T 2817, AAR M-107/208, BS 5892-3, IRS R-34 and EN 13262.
