China ZK1 Cast Steel Three-Piece Bogie - Quality Suppliers & Factory Components for Ultimate Performance
Basic Information
The ZK1 type bogie belongs to a cast steel three piece bogie with variable friction damping device. An octagonal rubber shear pad is added between the adapter and the side frame, which utilizes longitudinal and transverse shear deformation characteristics and upper and lower positioning structures to achieve elastic positioning of the wheel set.
✔
Curve Performance: When the vehicle passes through a small radius curve, the lateral force of the wheel rail can be reduced, thereby reducing wheel edge wear.
✔
Anti-Diamond Stiffness: A side frame elastic cross support device improves anti-diamond stiffness by 4-5 times compared to traditional three-piece bogies.
✔
Hunting Motion Control: Employs a double action constant contact rubber side bearing to restrain hunting motion through friction torque.
The central secondary suspension adopts a two-stage stiffness spring device that compresses the outer circular spring first, improving the static deflection of the empty car spring. The structure and parameters of the inclined wedge variable friction vibration damping device have been designed with wear-resistant materials to improve service life. The basic braking device adopts freight components and standard components, which are convenient for use and maintenance.
🚀 The above measures have played a good role in improving the operating speed, safety, and stability of the wagon.
