The invention relates to the technical field of rail transit equipment, and discloses a use method of a rail transit train bogie, the rail transit train bogie comprises a connecting plate, the middleof the bottom end of the connecting plate is fixedly sleeved with a bearing, the middle of the bearing is fixedly sleeved with a fixing shaft, and the bottom end of the fixing shaft is fixedly provided with a buckling block; and a first fixing frame is fixedly installed in the middle of one side of the buckling block, a first damping connecting piece is fixedly installed on one side of the first fixing frame, a first transverse buffer frame is fixedly installed on one side of the first damping connecting piece, and one side of the bottom of the first transverse buffer frame is movably sleevedwith a first longitudinal buffer frame. According to the rail transit train bogie, the first wheel set and the second wheel set are both half shafts, and one end of the first rotating shaft and one end of the second rotating shaft are in transmission connection through the balance spring, so that the load of an outer wheel track is reduced when the bogie turns over, the load of the wheel track iseffectively reduced, the abrasion of the wheel track is reduced, and the fault rate of the bogie is effectively reduced.
Description
[0001] This case is a divisional application with the application number CN201810290829.8, the application date is April 3, 2018, and the title is "A Rail Transit Train Bogie". technical field [0002] The invention relates to the technical field of rail transit equipment, in particular to a method for using a rail transit train bogie. Background technique [0003] The bogie is an independent part of the vehicle. The connection between the bogie and the car body should be reduced as much as possible. The various parameters of the bogie also directly determine the stability of the vehicle and the ride comfort of the vehicle. In order to increase the load, length and volume of the vehicle and increase the speed of the train to meet the needs of the development of railway transportation. [0004] The independent components assembled from the components and devices of the running part of the rolling stock play the role of supporting the car body, steering and braking, and ensure...
