Description

Technical Field

[0001] This utility model relates to the field of rail vehicle chassis structure technology, and in particular to an articulated monorail vehicle chassis. Background Technology

[0002] Currently, the traditional monorail elevated sightseeing vehicle chassis design often employs thick plate welding for the chassis traction beam and side longitudinal beams to ensure structural rigidity and strength. This results in a cumbersome structure, a large amount of welding work, and directly increases the pressure on the vehicle's drive and electrical control systems, leading to a decrease in passenger capacity and rescue capabilities. Furthermore, the existing technology suffers from a weak intermediate traction beam with limited traction force, and the chassis rigidity is low, resulting in poor passenger safety and experience.

[0003] In summary, there is an urgent need for an articulated monorail vehicle chassis that can significantly reduce structural weight while ensuring structural strength and rigidity. Utility Model Content

[0021] The application of the technical solution of this utility model has the following beneficial effects:

[0022] An articulated monorail vehicle chassis includes a main frame, a sleeper beam, and a traction beam. The main frame includes two sets of parallel longitudinal beams and two sets of side crossbeams connecting the two sets of longitudinal beams. The sleeper beams are parallel to the side crossbeams, with both ends connected to the two sets of longitudinal beams. The traction beams are parallel to the longitudinal beams, with both ends connected to the two sets of side crossbeams, and the traction beams pass through the sleeper beams and are fixedly connected to them. A traction plate is provided on the traction beam.

The design of the side crossbeams simplifies the stress distribution on the longitudinal beams. Furthermore, the chassis structure of this invention is easy to construct. The original design required preparing various specifications of profiles and plates, and involved a large amount of welding work; this patented structure uses mostly the same or similar specifications of profiles, simplifying material preparation and reducing welding work, thus saving more than 30% of manufacturing time.

[0023] In addition to the objectives, features, and advantages described above, this utility model has other objectives, features, and advantages. The present utility model will now be described in further detail with reference to the figures. Attached Figure Description

[0027] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in many different ways as defined and covered by the claims.

[0028] refer to Figure 1 A hinged monorail vehicle chassis includes a main frame, a sleeper beam 4, and a traction beam 2. The main frame includes two sets of parallel longitudinal beams 1 and two sets of side crossbeams 3 connecting the two sets of longitudinal beams 1. The sleeper beam 4 is parallel to the side crossbeams 3, and its two ends are respectively connected to the two sets of longitudinal beams 1. The traction beam 2 is parallel to the longitudinal beams 1, and its two ends are respectively connected to the two sets of side crossbeams 3. The traction beam 2 passes through the sleeper beam 4 and is fixedly connected to the sleeper beam 4. A traction plate 6 is provided on the traction beam 2. The entire structure is "eye" shaped, bearing the pressure of the upper carriage, including the pressure of the upper structure itself and the passengers. The traction plate is the traction hinge point, and together with the traction beam, it bears the function of transmitting traction force.

[0029] The articulated monorail vehicle design of this embodiment, with its side crossbeams connecting to the side longitudinal beams, can effectively distribute the pressure from the superstructure and passengers on the side longitudinal beams, avoiding excessive stress, and can also be used to suspend heavier undercarriage electromechanical components.

[0030] The underframe is also equipped with lifting points to lift the articulated monorail vehicle underframe and the entire carriage on it.

[0031] The design of the side beams, with their simple structure, distributes the stress on the side longitudinal beams.

[0032] Multiple sets of the bolster beams 4 are evenly distributed along the length of the side longitudinal beams 1, and the traction beam 2 passes through multiple sets of bolster beams 4 and is fixedly connected to multiple sets of bolster beams 4.

[0033] Multiple sets of the traction beams 2 are evenly distributed along the length of the side crossbeams 3, and the traction plate 6 is simultaneously connected to multiple sets of the traction beams 2.

[0034] The multiple sets of traction beams 2 are connected by a truss structure.

[0035] The side beams 3, the pillow beams 4, and the traction beams 2 are all provided in two layers along the height direction of the main frame;

[0036] The two layers of side beams 3, the two layers of pillow beams 4, and the two layers of traction beams 2 are all connected by a truss structure.

[0037] The main frame is square.

[0038] A reinforcing crossbeam is also provided between the two sets of side longitudinal beams 1;

[0039] The side beams 3 are also provided with reinforcing longitudinal beams that connect the two sets of side beams 3 respectively.

[0040] The side crossbeam 3 is also provided with a bearing plate 5, which rests on the lower bogie and is slidably disposed relative to the bogie.

[0041] The entire structure of the articulated monorail vehicle chassis is welded from profiles. The traction beam, side crossbeams, and sleeper beams, assembled by welding small profiles, together with the side longitudinal beams, form a lightweight and stable structure.

[0042] The traction beam, side crossbeam, and sleeper beam are all designed as a double-layer truss structure, which ensures both strength and rigidity.

[0043] The profile is a square tube.

[0044] In this embodiment, the chassis structure has been changed from the original main beam, sleeper beam, and side longitudinal beam structure to a quilted structure. The main beam consists of a double-layer quilt, which significantly reduces the weight of the structure. Calculations have verified that the original design chassis weight was 469.4 kg, while the optimized structure reduces the weight to 341.6 kg, a design weight reduction of 27.2%, which is a significant weight reduction effect. Secondly, the chassis structure of this embodiment is easy to construct. The original plan required the preparation of various specifications of profiles and plates, and the amount of welding work was large. The structure of this patent uses mostly the same or similar specifications of profiles, which simplifies the preparation of materials and reduces the amount of welding. It saves more than 30% of manufacturing time.

[0045] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
