Abstract

The invention provides a bogie frame, a bogie, a rail vehicle and a rail transit system, and belongs to the technical field of rail vehicles. The bogie frame comprises two parallel side beams, two endbeams and a supporting frame connected with the two side beams. Each side beam is provided with a first mounting position for mounting a wheel set; the two end beams are arranged at the two ends of the same side beam respectively, and a closed shape is defined by the two end beams and the two side beams. A second mounting position for mounting a rubber wheel is arranged on the front end beam; thesupporting frame is located between the first installation position and the second installation position and used for installing the traction device and the suspension device. The invention further provides a bogie, a rail vehicle and a rail transit system. According to the bogie frame, the bogie, the rail vehicle and the rail transit system, self convergence of the frame structure is achieved, the mode that the steel wheels and the rubber wheels are combined is adopted, excitation sources in the vehicle running process are reduced, and the stability and running stability of the bogie are improved.

Description

technical field [0001] The invention belongs to the technical field of rail vehicles, and more specifically relates to a bogie frame, a bogie, a rail vehicle and a rail transit system. Background technique [0002] With the increase of population, the traffic pressure is increasing, and the development of rail transit can solve the problem of urban public transportation very well. Moreover, the social and economic ties between cities are closer, people travel more frequently between cities, and fast and convenient articulated vehicles have become the most convenient means of transportation. It is an inevitable trend in the development of railway vehicles to meet the requirements of low platforms, multi-point stops, large starting acceleration, and fast boarding and landing. [0003] The most critical issues of rail vehicles are stability and safety. How to make rail vehicles have high indicators of stability and safety has always been the direction of vehicle research today...
