AAR standard narrow railway bogie

The standard  railway bogie are produced under the cooperation between CRRC Taiyuan   who took swing-type bogies as prototype. The new railway bogies have such features as three-pieced cast structure, bolster spring for secondary level suspension and swinging mechanism for primary suspension, and two leveled longitudinal and horizontal rigidity, improving a great deal horizontal flexibility of the vehicle, minimizing wearing-down between wheels and tracks, and elevating operation quality.

K5 railway bogie



K6 Bogie
3D axle welded railway bogie
GDT wide gauge track railway bogie
GDT bogie mainly consists of side frame, bolster, bearing spring, shock absorber, wheel pair, bearing, base braking equipment, side support and etc. The bogie is “three parts” cast steel controllable bogie produced by Brazil CVRD company; F bearing is adopted; the gauge is 1600mm wide track bogie.

GDE meter-gauge track bogie
GDE meter-gauge track railway bogie mainly consists of bogie bolster, bogie frame, wheel pair, bearing, adapter, base braking equipment, bearing spring, inclined wedge, inclined wedge spring, side support and etc. The bogie is a typical “Ride Control” control bogie; comparing with Chinese 8A bogie, the bogie adopts controllable inclined wedge shock absorber to improve rigidity of rhombus displacement among “three parts” and the operational stability.

14 ton meter-gauge railway bogie for Vietnam

14 tons meter gauge railway bogie for Vietnam is of three-piece structure, consisting of bolster, side frame, wheel set, 5×9 double taper rolling bearing, basic brake device and vibration-control device. The bolster, side frame and adapter adopt AAR-C grade steel to ensure enough strength and rigidity. Wheel set adopts the wheel with radius of 780mm. The wheel tread is LM meter gauge wearing type. The bearing device is 5×9 SKF double taper rolling bearing. The vibration-control device adopts Ride Control constant frictional damper and ADI wedge. The center spring is of equal height inner and outer spring made of 60SI2CrVA material. The bogie adopts center plate loading mode. The center plate is Φ299mm flat lower center plate. The side bearing is rigid side bearing with small clearance. The basic brake device is single sliding brake. The brake block is highphosphorous brake blocks.

Cast steel railway bogie for Pakistan
Casting Steel Bogie for Pakistan is three-piece cast steel railway bogie, main consisting of bolster, side frame, wheel set, lower center plate, elastic side bearing and basic brake device. The bogie adopts frictional vibration-control device, with wedge made of wearing resistance material and imported E 6×1double taper rolling bearing. The brake device is single side mid-phosphorous brake block. The side frame and bolster are made of B grade steel.
