The difference between a railway wagon to 8B bogie and a transfer to 8G

Turn 8 series bogie includes turn 8, turn 8A, turn 8AG, turn 8G, with G is mainly to increase the lower cross support device, increase the bogie stiffness and shear stiffness.

The braking device of the bogie of the railway passenger car and the freight car is relatively the passenger car bogie.

The first and second series are simple to suspension, and generally do not set speed and temperature sensors. The truck bogie is mostly of the "three pieces" type, and the bus bogie is integrated. **For the traction part, the truck bogie adopts the center pin, while the bus bogie is diversified.

Railway passenger wagons are generally composed of five basic parts: car body, bogie, coupler buffer device, braking device and vehicle internal equipment.

Bogie: The running part of the vehicle, its function is to support the car body, steering and braking, to ensure that the vehicle can run smoothly on the track.

Uses: Passenger car bogies are used to carry passengers, pay attention to speed and passenger comfort. Trucks are used to load goods, focusing on their carrying capacity. The speed of bus steering is also significantly higher than that of truck bogies.

Manufacturing: Most of the truck bogies are cast frames, and a small part of the speed-up frames are welded frames. The bus bogie is mostly a welded frame.

L to 8B is a derivative of 8G, at the beginning there was no 8B this model, 8AG and 8G after the use of found that can not meet the requirements of 100 kilometers per hour and other quality problems, and later improved the transformation, the improved 8B and 8AB operating speed reached 120 kilometers per hour. The letter "T" is added to the code of the vehicle model after the perfect transformation, and the letter "T" is changed to "E" for the vehicle model that has not been perfectly transformed

Turning K6 is similar to turning K2, and the lower cross supports the three-piece structure;

The K7 is a three-piece structure of Sunzhen's two U-shaped sub-frame self-guided Bizhi Xiang mechanism hand Kaimin type, the side frame guide frame is short, and the appearance of the bearing saddle changes the most.

No, there are K7s.

On September 7, the Ministry of Railways finalized the 25T axle load sub-frame radial bogie of China CSR Meishan Vehicle Factory into a K7 bogie. This is another kind of heavy-duty truck bogie with an axle load of 25t and a commercial operating speed of 120km h finalized by the Ministry of Railways after the K5 and K6 bogies. This is also the first time that the bogie of the quasi-gauge railway wagon independently developed by the Meishan plant has been finalized by the Ministry of Railways.

I only know that there are heavy duty and ordinary truck bogies, and the bogies are selected according to the load and critical speed.

For conducting static electricity, the static electricity of the car body is conducted to the wheelset and grounded through the rail.
