◪  1.Central axle pedestal

The central axle is made of premium low alloy seamless steel pipe, and processed by tempering and various high precision processing techniques. Thus the axle’s strength is greatly enhanced. The panel is made of high-strength low alloy steel plate by punch forming technique, so it is strong and durable. Other supporting accessories are all welded by high-strength low alloy plate. The central axle pedestal comes with stiffening girder in it, making the whole structure of our bogie suspension highly resistant to the twisting force and bending force.

◪  2. Central bearing pedestal

The anti-wear sliding bearing (with copper bush) embedded design is adopted. Thus the central axle and the bearing are more stable and have longer service life.

◪  3.Leaf spring pedestal

The nodular cast iron is used for the leaf spring pedestal of our bogie suspension to make it more anti-wear and impact resistant. The coupler between leaf spring pedestal and leaf spring assembly comes in rubber inner-bushing and separating design, which can effectively lower the abrasion coefficient between the leaf spring and spring pedestal, and make the service life of the two components longer.

◪   4. Leaf spring

The leaf spring is made of high-strength alloy leaf spring, and processed by advanced European processing techniques. The spring of our bogie suspension features high strength, great durability and is highly interchangeable.
