Fig. 1 to Fig. 7 is please referred to, the present embodiment provides a kind of bogies, comprising: framework, connector 4 and braking flap seat 5.
Framework includes two curb girders 1 and two crossbeams 2；Two curb girders 1 are arranged in parallel, two crossbeams 2 be arranged in parallel in two curb girders 1 it
Between, and curb girder 1 is vertically arranged with crossbeam 2；The both ends of crossbeam 2 are fixed with two curb girders 1 respectively；One curb girder 1 towards another
The inner surface of curb girder 1 is formed with connecting hole.Connector 4 includes interconnecting piece 41, mounting portion 42 and fixed part 43, and interconnecting piece 41 protrudes into
In connecting hole, and it is fixedly connected with curb girder 1；Mounting portion 42 is fixed between interconnecting piece 41 and fixed part 43, and fixed part 43 is used for
It is connect with braking flap seat 5；And the cross sectional dimensions of mounting portion 42 from close to interconnecting piece 41 one end to far from interconnecting piece 41 one
End is gradually reduced.
Specifically, bogie can be used in rail vehicle.Bogie may include framework, and framework can be used for carrying system
The components such as dynamic device, motor.Framework is fixed with connector 4, and connector 4 can be used for installing braking flap seat 5, and braking flap seat 5 can
To be connect with brake apparatus, so that brake apparatus is fixed on bogie.
Main structure of the framework as bogie, can be disposed in parallel by two curb girders 1 disposed in parallel and two
Crossbeam 2 forms, and can have certain distance between two curb girders 1, and two crossbeams 2 are arranged between two curb girders 1, crossbeam 2
Both ends can be respectively welded on two curb girders 1, and two curb girders 2 are located at the part between two crossbeams 2 can use to lower recess
In installation suspension arrangement.Curb girder 1 can have multiple plate structures to be welded box typed structure, and crossbeam 2 can columned pipe
Shape structure.Curb girder 1 and crossbeam 2 can be hollow structure, so as to mitigate the weight and intensity of bogie.Curb girder 1 and cross
Beam 2 be fixedly connected mode can there are many, it is preferable that curb girder 1 and crossbeam 2 can be fixed together by welding, to mention
The intensity of high framework.
It could be formed with the connecting hole for installation connecting element 4 on curb girder 1, connecting hole setting is in a curb girder 1 towards another
