The invention relates to a railway wagon
bogie and side frame cross bar mechanism connection method. The railway wagon
bogie and side frame cross bar mechanism connection method is characterized in that the
relative motion between two side frames within the horizontal plane is eliminated by a five-bar mechanism, so that a stable structure is achieved. The five-bar mechanism comprises three connecting bars and two bars formed by the two side frames, the two side frames are connected with both ends of the three connecting bars, so that the five-bar mechanism is formed in the horizontal plane, and the
relative motion between the two side frames within the horizontal plane is eliminated by the five-bar mechanism
assembly. Since the railway wagon
bogie and side frame cross bar mechanism connection method adopts the five-bar mechanism side frame
control principle and the five-bar mechanism side frame control mechanism on the basis of a conventional three-major
part type bogie, the defects of poor performance stability and
structural stability existing in currently used four-cross bar connection bogies are overcome, the
structural fatigue reliability of vehicles and the
critical speed of vehicle running are increased effectively, the dynamic acting force between wheels and rails is decreased, and thereby the purpose of increasing the running speed and running quality of wagons and reducing operation and maintenance costs is achieved.
