Problems solved by technology
[0002] The main structure of the current bolster is usually welded by aluminum alloy profiles. An anti-roll mounting seat is arranged on one side of the main structure of the bolster. When the vehicle is running, the anti-roll mounting seat will transmit the force to the bolster Structurally, since the bolster is stressed on one side, the bearing balance and fatigue resistance are poor
[0003] The anti-roll mounting seat of tailor-welded bolster structure of EMU currently in operation is pre-buried in the internal structure of the bolster, and the screw seat is installed in the anti-roll mounting seat, which is a tapping structure of the existing car. If the screw seat is damaged during the process, the replacement and repair of the anti-roll device cannot be realized

Embodiment 1
[0029] Such as figure 1 As shown, the figure schematically shows that the new vehicle body bolster structure includes a bolster main body 1 , an anti-roll mounting seat 2 and a screw seat 3 .
[0030] In the embodiment of the present application, the corbel main body 1 is tailor-welded from aluminum alloy profiles.
[0031] The anti-roll mounting seat 2 is arranged on both ends of the outer surface of the bolster main body 1, wherein the anti-roll rolling mounting seat 2 is configured as an open structure with the opening facing the outside, and on the bottom plate of the anti-rolling mounting seat 2 The upper surface of 21 is equipped with screw seat 3. Specifically, since the bolster main body 1 is installed on the underframe structure of the vehicle, it needs to carry the entire vehicle body structure, by installing anti-rolling mounts 2 on the two ends of the outer surface of the bolster main body 1 respectively, and making the anti-side roll The rolling mounting seat 2 ...

The present invention relates to the technical field of rail transit vehicle body structure, and discloses a novel car body bolster structure, comprising: a bolster main body; Two ends of the outer surface, wherein the anti-rolling mounting seat is configured as an open structure with an opening facing the outside, and a screw seat is installed on the upper surface of the bottom plate of the anti-rolling mounting seat. The new car body bolster structure has the advantages of effectively preventing unilateral force on the bolster main body and strong anti-fatigue properties, and also has the advantage that the anti-rolling mounting seat adopts an open structure, which facilitates the installation and replacement of the screw seat.
Description
technical field [0001] The invention relates to the technical field of rail transit vehicle body structure, in particular to a novel car body bolster structure. Background technique [0002] The main structure of the current bolster is usually welded by aluminum alloy profiles. An anti-roll mounting seat is arranged on one side of the main structure of the bolster. When the vehicle is running, the anti-roll mounting seat will transmit the force to the bolster Structurally, since the bolster bears force on one side, the bearing balance and fatigue resistance are poor. [0003] The anti-roll mounting seat of tailor-welded bolster structure of EMU currently in operation is pre-buried in the internal structure of the bolster, and the screw seat is installed in the anti-roll mounting seat, which is a tapping structure of the existing car. If the screw seat is damaged during the process, the replacement and maintenance of the anti-rolling device cannot be realized. Contents of ...
