K4 Railway bogie
The railway bogie
are produced under the cooperation
between Zhuzhou Wagon Works and ABC-NACO
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
This is a 25t shaft weight wag type railway
bogie developed based on K4 bogie. The bogie
is casting steel three parts wag bogie,
which follows the main structure of K4, the
spring plate is concave downward type
modified from flat type of K4, the base
braking adopts the L-c combined braking beam
developed by the shop own, the shock
absorber inter round spring, inclined wedge,
flexible side support and other parts are
mutually replaceable with K4.
K6 Bogie
K6 railway bogie is domestic main type 25t
shaft weight freight bogie. The bogie is
casting steel three parts structure. Bolster
and side frame are B casting steels. Side
beam is wide guide frame structure; a down
cross supporting device is additionally
arranged between two side beams; the first
suspension system is arranged with modified
shaft box rubber gasket; the second
suspension system is central bolster spring
suspension system with friction shock absorb
device.
3D axle welded
railway bogie
The railway bogie is D shaft bogie for K16A
mineral hopper and general large freight.
The structure is characterized in: 1.
Overall welded structure consists of side
beam, center plate beam, transversal beam
and end beam. All these beams are steel
plate welded enclosed box structure.
25t low power action structural freight wagon bogie
The railway bogie is a H frame consisting
of two side beams and a center plate beams,
which are welded together, a box type cross
section is adopted. Wheel-pair axle box
spring is supported in suspension through
the axle box spring; the internal and the
external springs with rigidity of class II
are adopted with different height, double
inclined wedge type axial box friction
reduction is adopted. Suspension sliding
type two-sides braking is used for the basic
braking equipment, brake head links with the
brake beam through pin shaft. The high
friction brake block is used.
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.
This bogie is suitable on open wagon, flat
wagon and box wagon stipulated in the
contract of supplying 1,300 freight vehicles
for Pakistan national railway.
