Embodiment 1

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

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

[0047] The framework includes:

[0048] Two side beams 110, the two side beams 110 are arranged oppositely;

[0049] at least one beam connecting 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 beam, and the two extension beams 130...

Embodiment 2

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

[0072] Since the rail vehicle in this embodiment is provided with the bogie described in the first embodiment, the span between the two secondary suspensions on the bogie is relatively large, which is beneficial to improve the anti-rolling ability of the bogie and reduce the anti-rolling ability of the bogie. The pressure of the roll torsion bar.

Abstract

A framework, a bogie and a rail vehicle are provided in the embodiments of the present application. The framework includes two side beams, at least one cross beam and two extension beams. The two side beams are arranged opposite to each other; the cross beam connects the two side beams; The beams are respectively arranged on the side of the two side beams away from the cross beam, and the two extension beams are arranged coaxially, and the extension beams are provided with a secondary suspension mounting seat, which is used to connect the secondary suspension. In the embodiment of the present application, an extension beam is arranged on the side of the side beam away from the cross beam, and a secondary suspension mounting seat is arranged on the extension beam, thereby increasing the span between the two secondary suspensions on the bogie and improving the bogie roll resistance.

Description

technical field [0001] The present application relates to a rail vehicle manufacturing technology, and 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 the 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, flexibly running along a straight line and Pass the curve smoothly; ease the interaction between the vehicle and the wheel-rail, reduce vibration and shock, and improve the running stability and safety of the vehicle. According to the setting position of the axle box, the bogie can be divided into the axle box external bogie and the axle box built-in bogie. [0003] In the solution of the related art, the axle box built-in bogie includes a whee...
