Embodiment
In the structure of rail vehicle, framework 1 is rotatably connected with one end of axle box by positioning node, and framework 1 is also
Connected by the other end of primary spring and axle box.Axle box is also rotatably connected with axle.When framework 1 is subject to external force, there is two
Bar route of transmission, first route of transmission is that the external force on framework 1 is transferred to axle box by positioning node, then is transferred to axle,
The wheel being connected with axle is then passed to, Article 2 route of transmission is that the external force on framework 1 is transferred to axis by primary spring
Case, then axle is transferred to, it is then passed to the wheel being connected with axle.
In practical applications, when framework 1 is subject to vertical force, due to having rotation relation between one end of axle box and framework,
The other end also has rotation relation with axle, causes vertical power not load in one end that axle box is connected with framework 1.Therefore,
When framework 1 is subject to vertical force, the route of transmission of power passes sequentially through framework 1, primary spring, is connected with primary spring on axle box
One end, axle, wheel.In rail vehicle, primary spring, axle, the position of wheel are and and structures point-blank
Plane where frame 1 is vertical, that is to say, that framework 1 is after vertical external force is subject to, direction and the place of framework 1 that external force is propagated
Plane it is perpendicular.
In practical applications, when framework 1 is subject to cross force and longitudinal force, most routes of transmission of external force are successively
By one end for being connected on framework 1, axle box with framework 1, axle, wheel, the only route of transmission of very small part power in external force
It is to pass sequentially through framework 1, primary spring, the one end being connected with primary spring on axle box, axle, wheel.
Signified vertical refer to, perpendicular to the direction on 1 surface of framework (Z), laterally refer to parallel it should be noted that above-mentioned
In the direction of crossbeam 12 (Y), longitudinally refer to the direction (X) parallel to curb girder 11.
Fig. 2 is a kind of structure chart of fixing device for bogie frame fatigue test provided in this embodiment.
It is used for bogie frame fatigue test fixing device as shown in Fig. 2, provided in this embodiment, including：
