It is most easily obtained on many existing three-piece bogies equipped with wide wedges. Swedish Ore Company and the South African Railway Department have jointly launched a new type of iron ore truck for transporting iron ore. The vehicle adopts a newly improved South African Scheffel self-guided bogie. This self-guided bogie mainly involves great changes between the axlebox and the side frame, and adds an auxiliary frame for wheelset guidance. The specific structure is that the self-guided bogie is equipped with a series of rubber springs on the axle box. At the same time, an auxiliary frame is installed between the two axle box rubber springs of the wheel pair and the side frames. There is a total of 2 auxiliary frames for one bogie. They are installed against the bolster respectively, and the auxiliary frames are connected by ball joints and stabilizers, and they are not connected by the previous bushings, thus ensuring the straight running stability and the radial position of the wheel pairs when passing the curve. Another feature of the bogie is that due to the guiding and stabilizing mechanism, the lateral stiffness of the wheelset is small (only 800N/mm), so that when the vehicle is on the curve, even if the wheel/rail adhesion coefficient is small, it can make The wheel pair is in a radial position.
The smaller lateral stiffness of the wheelset also reduces lateral forces and wear between wheels and rails. In order to study the dynamic performance of the bogie, dynamic simulation calculations and dynamic tests were performed successively. The MEDYNA program software was used to simulate and analyze the dynamic performance and optimize the parameters. The calculation results show that the bogie has sufficient operational stability, stability and safety.
