Seat adapts to crossbeam and curb girder is smooth excessively, improves the bearing structure of beam body transition region.
In order to improve bearing structure during bogie distortion, the end carriage is middle recessed U-shape structure, the end carriage
End connected with the respective end of curb girder by end carriage connecting seat.
Based on same inventive concept, present invention also offers a kind of bogie, and it includes described framework；It is it is preferred that described
Bogie is low-floor bogie.
Based on same inventive concept, present invention also offers a kind of rail vehicle, and it includes described bogie.
The spar both ends of the present invention are arranged with motor mount, turn it is achieved thereby that bogie motor installation center of gravity is located at
To frame symmetrical centre.
Compared with prior art, the beneficial effects of the invention are as follows：The present invention is on the basis of conventional bogie framework, in side
Spar is set up outside beam, efficiently solves magnetic rail brake device and motor mounting space collision problem, and realizes that bogie motor is pacified
Dress center of gravity is located at bogie symmetrical centre, improves the stability of vehicle operation.Truck transom and the curb girder of the present invention, curb girder with
Smoothness is realized between end carriage, curb girder and spar excessively, at utmost optimizes low-floor steering while improving framework contour structures
Frame bearing structure and installing space.The framework of the present invention meets the various parts installation requirement of low-floor bogie.
