Independent axle Bridge
The axle is a cylindrical object worn in the middle of the bearing or in the middle of the wheel, but there are also a few parts that are square. Axle bridge is a mechanical part that supports the train wheel to rotate and rotate with it to transmit motion, torque and bending moment. The parts of the machine for rotary motion are mounted on the axle.
Metro traction beam
The metro traction beam is used to realize the connection between the locomotive and the vehicle, the vehicle and the vehicle, and the traction force and the impact force, and the vehicle can keep a certain distance between the vehicle and the vehicle.
Axle box
In railway locomotives and vehicles, set in shaft neck uplink node wheel and steering frame or two axis vehicle body components, referred to as the crankcase. Its function is to transfer the weight of the body and the load to the wheel, the lubrication journal, reduce friction, the running resistance. The axle box device is divided into two types: plain bearing box device and rolling bearing box device. In early twentieth Century, the rolling bearing box device was used in the early stage of locomotive and rolling bearing. China railway passenger cars and diesel locomotives and electric locomotives all have used rolling bearing box.
