Charpy beam type straddle type monorail vehicle two-axle power bogie

Abstract

The invention discloses a simply supported beam type straddle type monorail vehicle biaxial power bogie, comprising a support frame and a running wheel assembly, the support frame is provided with a running wheel installation cavity, and the running wheel assembly is arranged on the running wheel In the installation cavity, the innovation is that the support frame and the running wheel assembly adopt a simply supported beam structure; the beneficial technical effect of the present invention is: a new simply supported beam type monorail vehicle bogie support structure is provided, which can effectively Improve the stress of the structure and solve the problem of tire eccentric wear.

Description

technical field [0001] The invention relates to a straddle type monorail vehicle, in particular to a simply supported beam type straddle type monorail vehicle double-axle power bogie. Background technique [0002] At present, the support shafts used to support the running wheels on straddle-type monorail vehicles all adopt a cantilever beam support structure. The outer end of the support shaft is connected with the power assembly, and the power assembly is arranged The inner end is suspended and located inside the support frame, and the running wheel is sleeved on the inner end of the supporting shaft. The design purpose is: due to the huge stress on the running wheel, the wear is fast, and the maintenance period is short, so that it is easy to disassemble the running wheel. Considering the angle, the prior art adopts the aforementioned design. When dismounting, the supporting shaft and the traveling wheels can be moved out from the opening on the support frame. After the ma...

[0002] At present, the support shafts used to support the running wheels on straddle-type monorail vehicles all adopt a cantilever beam support structure. The outer end of the support shaft is connected with the power assembly, and the power assembly is arranged The inner end is suspended and located inside the support frame, and the running wheel is sleeved on the inner end of the supporting shaft. The design purpose is: due to the huge stress on the running wheel, the wear is fast, and the maintenance period is short, so that it is easy to disassemble the running wheel. Considering the angle, the prior art adopts the aforementioned design. When dismounting, the supporting shaft and the traveling wheels can be moved out from the opening on the support frame. After the maintenance operation is completed, the supporting shaft and the traveling wheels can be installed together on the supporting frame. The existing problems are: due to the adoption of the cantilever beam support structure, the negative stress borne by the support frame is relatively concentrated, the force is uneven, and the stress in the local area is huge. At the same time, the load on the traveling wheels is also unevenly distributed. The tires have eccentric wear, and due to the special structure, the spoke-type rim cannot be used, and only special hubs with large volume and complex structure can be used. This kind of hub not only has high cost, but also has high quality. The assembly, supporting shaft, and running wheel can be disassembled as a whole, but the subsequent tire replacement operation is still very cumbersome, time-consuming, and inefficient; in addition, because the supporting shaft needs to bear huge stress, the supporting shaft is not only huge in mass but also complex in structure
