The invention provides a bogie frame, a bogie, a rail vehicle and a rail transportation system, and belongs to the technical field of rail vehicles. The bogie frame includes two side beams parallel to each other, two end beams and a support frame connecting the two side beams; each side beam is respectively provided with a first installation position for installing wheelsets; the two end beams are separately arranged on the same The two ends of the side beam form a closed figure with the two side beams; the second installation position for installing rubber wheels is arranged on the front end beam; the support frame is located between the first installation position and the second installation position, and is used For the installation of traction and suspension devices. The invention also provides a bogie, a rail vehicle and a rail transit system. The bogie frame, bogie, rail vehicle and rail transit system provided by the present invention realize the self-convergence of the frame structure, adopt the combination of steel wheels and rubber wheels, reduce the source of disturbance in the operation of the vehicle, and improve the performance of the bogie. stability and smooth operation.
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...
