Body passing through the center pins on bolster traction, bolster and frame air spring vertical connections between vertically connected by drawbar, motor rigid suspension in architecture, between the frame and axlebox end connected by a vertical coil springs, the other end through metal rubber elastic hinge. Improved original bogies and bogies to ensure maximum versatility in the part, a suspension with a v-shaped rubber spring, canceled the original vertical springs and elastic hinge structure of axle-box positioning, also make corresponding changes to the framework, the main differences.
