Abstract:

In the article is stated developed new structure of horizontal bearer of two-axle bogie model 18-100 of gauge railways of 1520 mm. The bearer represents the box with two longitudinally arranged balls. The balls are performing only rotational motion related to axes of spatial coordinate system OXYZ at contact with bearer of freight car body. At touching occurs the rolling friction that virtually eliminates jamming of body on bogie at diagonal fitting on the bearers. For more smooth motion of carriage is proposed the presented structure with elastomer. Are defined the friction forces and movement forces drive moment on balls at touching with bearers of freight car.
