Railway freight car introduction to the composition and function

Railway freight car introduction to the composition and function - 2020 02 - 15 bogie is the supporting body device, bogie supporting body ( Also known as the bogie load mode) Should satisfy two basic requirements: safe and reliable supporting body, bearing and pass all the forces ( Such as the vertical force, vibration, etc. ) ； Through curve, the vehicle body between the bogie and should be able to around the center of rotation relative rotation. Wheel bogie composition and the effect of mixer and bearing assembly: wheel for rolling along the rail, transfer vehicle weight and wheel/rail forces between ( Including the traction and braking force) ； Axle box contact bearing assembly structure ( Or side of the frame) , and the transformation of wheel to scroll to car body translation along the rail. Mixer architecture ( Or side of the frame) : architecture ( Or side of the frame) Is the basis of the bogie, it the bogie of the zero, parts as a whole. The elastic damping device: bogie on the wheels and the frame ( Side frame) Or between architecture ( Side frame) With the car body ( Bolster) Between the elastic suspension device; The former is called the axle box linkage ( Also known as the first suspension) , which is called roll pillow ( The central) Suspension ( Right according to the second suspension) 。 Foundation brake: in order to make the running vehicle parking in within a prescribed distance, must be installed braking device, its role is to transfer and amplification cylinder brake force, bogie in friction between the brake shoe and wheel into the friction between the wheel/rail, the braking force, so that the vehicle under the direction of the resistance, the braking effect. （ Source: the resources of railway vehicle platform)
