Maanshan Kingrail Technology Co.,Ltd supply various bogies, such as K1,K2,K3,K4,K5,K6, S-2 barber, swing motion bogies, used for wagons, locomotives, metro for railway, mining field.
The bogie is one of the most important components in the structure of rail vehicles. Its main functions are as follows:
1) The bogie is used on the vehicle to increase the vehicle's load, length and volume, and to increase the train's running speed to meet the needs of the development of railway transportation;
2) Ensure that under normal operating conditions, the car body can be reliably seated on the bogie, and the rolling of the wheels along the rails is converted into the translation of the car body along the line through the bearing device;
3) Support the car body, bear and transmit various loads and forces from the car body to the wheels or from the wheel rail to the car body, and evenly distribute the axle weight.
4) Ensure the safe operation of the vehicle, and be able to run flexibly along a straight line and pass through curves smoothly.
5) The structure of the bogie should facilitate the installation of the spring damping device, so that it has good damping characteristics, so as to ease the interaction between the vehicle and the line, reduce vibration and impact, reduce dynamic stress, and improve the stability and safety of vehicle operation.
6) Make full use of the adhesion between the wheel and the rail, transmit traction and braking force, amplify the braking force generated by the brake cylinder, so that the vehicle has a good braking effect to ensure that it stops within the specified distance.
7) The bogie is an independent component of the vehicle, and the number of connecting parts between the bogie and the vehicle body should be reduced as much as possible.
