Traction systems are core components in mechanical engineering, transmitting traction or braking forces, and have typical applications in rail transit equipment. For urban rail vehicle bogie systems, this device employs a double-sided obliquely symmetrical traction rod structure to achieve power transmission. Together with the articulated device, it forms the bogie system. Its reliability at 100 km/h is verified through 3D modeling and dynamic simulation. In the field of high-speed trains, the 400 km/h bogie design adopts a center pin and double traction rod combination structure. Vertically crossed bolts are used to avoid increasing lateral stiffness, and a flexible rubber connection is used to achieve longitudinal force transmission.
In rail transit vehicle bogie systems, the traction system, as a key connecting component, is mainly responsible for the longitudinal force transmission between the car body and the bogie. The use of two obliquely symmetrically distributed traction rod structures meets the requirements of vehicle lightweighting while achieving reliable power transmission. This technology has been developed into a center pin double traction rod combination structure suitable for 400 km/h high-speed trains.
