Description

Technical Field

[0001] The present invention relates to the technical field of the running gear of maglev vehicles, and particularly to a frame - type suspension frame applicable to low - vacuum pipeline superconducting electro - magnetic levitation. Background Art

[0002] According to relevant data, after the speed of existing rail transit vehicles reaches 600 km / h, the ratio of air resistance to the total resistance reaches more than 90% and the vibration is intense. Coupled with factors such as mechanical friction and adhesion coefficient, it severely restricts the further increase in the speed of rail transit trains. As a new type of transportation system, low - vacuum pipeline maglev transportation operates in a low - pressure pipeline, and the air resistance has less impact on it, enabling the train to reach a higher operating speed. It is an ideal future means of transportation.

[0003] The suspension frame is one of the core subsystems of a low - vacuum pipeline maglev train, and the suspension frame structure is the skeleton of the suspension frame. As a key component of the suspension frame, in addition to bearing and transmitting various forces, it also needs to integrate all the components of the suspension frame into a whole. Interfaces for superconducting magnets, support and guiding wheel devices, suspension devices, quench protection devices, etc. are provided on the frame. This requires that the suspension frame structure not only meets the functions of traditional rail transit frames, but also be non - magnetic and have sufficient length to accommodate the installation interfaces of superconducting magnets. While meeting the load - bearing requirements, the suspension frame structure needs to minimize its own structural weight as much as possible to meet the mass ratio of above - spring and below - spring, ensure the running stability of maglev vehicles, overcome the "negative damping" phenomenon of the electro - magnetic levitation system. At the same time, a lighter structural weight means an increase in the effective load of maglev vehicles and a reduction in energy consumption.

[0004] In the existing suspension frame structure, load - bearing and load transfer are mainly carried out through large - area planes, resulting in low structural utilization efficiency, heavy frame weight, large unsprung mass, a relatively serious "negative damping" phenomenon in the electro - magnetic levitation transportation system, and poor vehicle dynamics performance. Moreover, this leads to an increase in the thrust of the suspension and propulsion system, an increase in energy consumption, and poor operation economy. Also, due to the extensive use of planar structures, the passing - through performance of hydraulic pipelines and cable networks is poor. Summary of the Invention

[0036] 4 sets of guide wheel mounting seats are fixed to the main structure of the frame by bolt connection. The guide wheel mounting seats provide a precise installation interface for the guide wheel device and ensure sufficient strength at the same time.

The main welds of the frame are all butt welds. Other mounting seats are aluminum alloy machined parts fixedly connected to the main structure of the frame by bolts. Under the condition of meeting the stiffness and strength, the large-area planar structure is changed to a frame-type load-bearing structure, greatly reducing the weight of the frame structure, weakening the "negative damping" phenomenon of electromagnetic levitation, and at the same time increasing the frame thickness to enhance the structural stiffness and strength. At the same time, the connection part structure of the end beam, crossbeam and side beam is retained, and the installation position structure of the support wheel and guide device is retained to ensure the integrity of the main load-bearing structure of the frame and the main load transmission route; Hourglass rubber spring interfaces are provided on the frame to install hourglass rubber springs, which can reduce the complexity of the suspension frame while ensuring the comfort of the vehicle; Safety cable and lateral stop mounting interfaces are provided on the frame to limit the lateral and vertical displacements of the carbody and ensure the smooth operation of the vehicle; An equipment mounting plate is provided on the frame for the installation of the hydraulic pipelines of the support wheel and guide wheel device, which is convenient for the disassembly and assembly above and below the spring; At the same time, the partition part of the frame-type structure can be used for the layout of hydraulic pipelines and cable networks, reducing the layout difficulty and saving costs.

[0049] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by orientation words such as "front, rear, upper, lower, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom", etc. is usually based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description. Without contrary explanation, these orientation words do not indicate and imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation on the protection scope of the present invention; the orientation words "inside, outside" refer to the inside and outside relative to the contour of each component itself.

[0050] For the convenience of description, spatial relative terms such as "above...", "over...", "on the upper surface of...", "above" etc. can be used here to describe the spatial positional relationship between a device or feature shown in the drawings and other devices or features. It should be understood that the spatial relative terms are intended to include different orientations in use or operation other than the orientation described in the drawings for the device. For example, if the device in the drawing is inverted, the device described as "above other devices or structures" or "over other devices or structures" will then be positioned as "below other devices or structures" or "under other devices or structures". Thus, the exemplary term "above..." can include both the orientations of "above..." and "below...". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and corresponding interpretations should be made for the spatial relative descriptions used here.

[0051] In addition, it should be noted that the use of words such as "first", "second", etc. to limit components is only for the convenience of distinguishing the corresponding components. Without otherwise stating, the above words have no special meaning. Therefore, it should not be construed as a limitation on the protection scope of the present invention.

[0052] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
