Embodiment 1

[0045] figure 1 Shown in is a schematic structural diagram of the framework provided by an embodiment of the present application; figure 2 Shown in is a schematic structural diagram of a bogie provided by an embodiment of the present application; image 3 Shown in is a schematic structural diagram of the bogie provided by an embodiment of the present application after omitting the bolster; Figure 4 Shown in is the structural diagram of the wheelset and the axle box provided by an embodiment of the application; please refer to Figure 1-Figure 4 .

[0046] This embodiment provides a frame 100 and a bogie including the frame 100 .

[0047] Framework includes:

[0048] Two side beams 110, the two side beams 110 are arranged opposite to each other;

[0049] At least one cross beam, the cross beam connects the two side beams 110;

[0050] Two extension beams 130, the two extension beams 130 are respectively arranged on the side of the two side beams 110 away from the cross ...

Embodiment 2

[0071] This embodiment provides a rail vehicle, including a car body and the bogie described in Embodiment 1 above, and the car body is arranged on the bogie.

[0072] Since the rail vehicle of this embodiment is equipped with the bogie described in the first embodiment above, the span between the two secondary suspensions on the bogie is relatively large, which in turn helps to improve the anti-rolling ability of the bogie and reduce the anti-rolling capacity of the bogie. Pressure on the roll torsion bar.

Abstract

The embodiment of the invention provides a framework, a bogie and a rail vehicle; the framework comprises two side beams, at least one cross beam and two extension beams, and the two side beams are oppositely arranged; the cross beam is connected with the two side beams; and the two extending beams are arranged on the sides, deviating from the cross beam, of the two side beams correspondingly, the two extending beams are coaxially arranged, secondary suspension mounting bases are arranged on the extending beams, and the secondary suspension mounting bases are used for being connected with secondary suspension. According to the embodiment of the invention, the extension beams are arranged on the sides, deviating from the cross beams, of the side beams, and the secondary suspension mounting bases are arranged on the extension beams, so that the span between the two secondary suspensions on the bogie is increased, and the side rolling resistance of the bogie is improved.

Description

technical field [0001] The present application relates to rail vehicle manufacturing technology, in particular to a frame, a bogie and a rail vehicle. Background technique [0002] The bogie is arranged between the car body and the track, and is one of the most important components on a rail vehicle. The main functions of the bogie are: supporting the car body, bearing and transmitting various loads and forces from the car body to the wheels or from the wheel rail to the car body; ensuring the safe operation of the vehicle, and being able to flexibly run along the straight line and Pass the curve smoothly; ease the interaction between the vehicle and the wheel rail, reduce vibration and shock, and improve the stability and safety of the vehicle. According to the installation position of the axle box, the bogie can be divided into the axle box external bogie and the axle box internal bogie. [0003] In the solution of the related art, the axle box built-in bogie includes a ...
