Forged Railway Spare Parts Train Bogie Coupler Yoke Good Mechanical Properties
Coupler yoke for Railway Wagon Frame of Trail hook for bogie (forging) is mainly used for the connection of the railway wagon hook catching device.

Train forged yoke, coupler, buffer, and other components of the coupler buffer device is a railway vehicle has a device that connects a vehicle to a vehicle (or a locomotive), pulls it, and eases an impact force during train operation, the train forged yoke is an important part of the coupler buffer device and a key component for installing the slave board, the buffer, and the traction force of the train vehicle.

Forged Coupler yoke for Railway Wagon Frame of Trail hook for bogie is mainly welded by a frame body and a connecting plate group. The frame body is made of a steel billet of 25MnCrNiMoA, and the forging ratio of the billet is ≥3. The billet is delivered by annealing or high-temperature tempering after hot rolling or forging.


Train Forged Center Plate
Train forged center plates ;are the components of railway wagon bogies, they can be cast and forged. Dimensions are 14'', 16'', and whatever the customer wants. When production, every center plate will be checked by a specialized inspector for the chemical and mechanical performance, so the quality will be good. ;

Functional, durable multi-tools ideal for road or trail-side use. Forged aluminum side plates, easy to grip while wearing gloves. Forged, Center-pivot stainless steel bits. Durable stainless steel fastening hardware. Forged aluminum chain breaker. Three-spoke wrenches are integrated into the chain breaker.


TEDRAIL supplies two types of center plates.

One is the Top Center Plate or Upper Center Plate as well as called Body Center Plate. It has been used on almost all wagon designs. A railroad car body has a longitudinally extending center sill, and the main bolster extends transversely relative to the center sill. ; The center plate is mounted under the center sill at the intersection of the center sill and the main bolster.

Another type of center plate is the Lower Center Plate as well as called the Bogie Center plate. Normally the center plate has been fixed on a truck bogie by bolts and nuts, which supports the railroad car body for rolling motion along the railroad tracks.

The upper center plate and the lower center plate are working together to link the car body and truck bogie to move forward.

The center plate is made by casting and machining. A Center plate is used on the bogie. It is the connection parts between the wagon body and the bogie.


Train Forged Knuckle
As one of the most important load-bearing parts, the train forged knuckle ;has a direct relationship with the safety in operation and reliability of the freight trains. Railway couplers are components designed for connecting rolling stocks on a train to transmit traction force and impact force, as well as to keep some distance between the rolling stocks. Knuckle throwers are a type of coupler. ;

Key features and advantages of ;train forged knuckles

100% forged from a single piece of steel

Innovative, patent-pending design

Weight parity with castings

Over 2.2 million fatigue cycles in testing: 3.7x the AAR minimum

Over two years of global heavy-freight service Meets or exceeds all AAR specifications

Reduced slack design


Forging Wheel
The forging wheel ;is created from a heated aluminum bar, which in its turn, is pressed at different steps by an 8000 t. press. Thus the wheel develops its rough cylindrical shape. The channel is then stretched using the flow-forming process, a technology used to stretch the material in the same direction. As a result, the granular flow of the aluminum is aligned even at the most critical points of the wheel. This ensures much greater support of the working loads. The wheel is then exposed to heat treatment so as to improve its mechanical properties.

A forging wheel is manufactured from a billet or a large square piece of solid metal. The billet is heated to extreme temperatures and pressurized to take its shape. This thermal cycle process causes forged wheels to be stronger than cast wheels due to grain refinement. Consistent forging makes for stronger structural integrity with less material compared to a cast wheel, however, the process costs more, rendering forged wheels the more expensive option.

Forging wheels offer several advantages. The manufacturing process results in a stronger wheel by eliminating cavities, porosity, and shrinkage. Due to their tighter grain structure, forged wheels are also mechanically stronger, ensuring better wear resistance over time. You also get better performance and handling because of this process.


Draft Gear
Outside of Western Europe, the majority of freight vehicles are equipped with knuckle couplers rather than hooks, screwcouplers, and buffers. While this system offers strong coupling between vehicles it provides little impact protection, particularly during train formation, and does not protect the freight from snatch forces when the train is running. Each coupler normally incorporates an energy absorption unit known as a draft gear. The majority of draft gears are equipped with steel springs, or rubber, combined with friction wedges to absorb and dissipate the energy.

The conventional draft gear ;is not an efficient absorber of energy and although it is large and heavy it only absorbs a small amount of energy 83kJ. Oleo has developed a hydraulic draft gear that offers 407kJ which is almost five times the energy absorption capability of a conventional draft gear.


Draft Gear Parts (Forged)
Forging has long been used in the manufacture of draft gears. This is particularly true for the production of gear blanks, which would subsequently be cut/machined into the final desired configuration. Gear blanks have been produced by open-die forging, closed-die forging (Figure 7), and hot upset forging. During the past 35 years, there has been considerable research and development aimed at producing near-net or net-shape gears by precision forging. Today, draft gear parts (forged) requiring little or no finish machining are commonly used in the automotive, truck, off-highway, aerospace, railroad, agriculture, and material handling industries, as well as the energy and mining fields.

Typical gear forgings:

The 4.5 kg (10 lb) gear was forged from 8620 steel billet 75 mm (3 in.) in diameter by 124 mm (4.9 in.) in length. An energy level of 353,000 J (260,000 ft · lbf) was needed to forge the gear in one blow at 1230 °C (2250°F). The web on the gear was forged to final thickness; the teeth were forged with 0.51 mm (0.020 in.) of stock for finish machining.
