Description

Technical Field

[0001] This utility model belongs to the technical field of straddle-type monorail transit vehicles, and more specifically, it relates to a vehicle body structure for straddle-type monorail transit vehicles. Background Technology

[0002] Straddle-type monorail vehicles are a type of rail transit where vehicles with rubber tires straddle a track beam that integrates the beam and rail. They are typically elevated, three-dimensional transportation systems with independent right-of-way. Maximum speeds can reach 80 km / h, with an average operating speed of 30-45 km / h, comparable to urban rail transit systems like subways and light rail. Key features include: 1. Excellent adaptability to terrain: straddle-type monorails have a maximum climbing ability of 100‰ and a minimum curve radius of only 46m. 2. Excellent environmental adaptability: using electric traction, there are no exhaust emissions like those of ordinary buses; the narrow monorail beam and support columns result in a small footprint, minimal obstruction, and less impact on sunlight; the absence of an overhead contact line provides good visibility and landscape; and the monorail has low noise and vibration, meeting environmental protection requirements. 3. Simple construction and short construction period. 4. Good economic efficiency, far lower than subway construction costs. However, existing straddle-type monorail car bodies use fully welded designs, and welding defects and constraints contribute to poor fatigue performance of the car body structure. The existing straddle-type monorail car body structure lacks bogie clearance, making a low-floor design impossible, which increases the vehicle's center of gravity and reduces stability. Furthermore, the existing straddle-type monorail car body structure uses a welded, monolithic construction, resulting in poor modularity and difficulties in deformation control.

[0003] Existing technology includes a body structure for a straddle-type monorail vehicle, published under license number CN207657820U. This technology discloses a body structure for a straddle-type monorail vehicle, comprising a body body including a roof, side walls, a chassis, and end walls. The roof, side walls, chassis, and end walls are all welded from large, hollow, double-surfaced extruded aluminum alloy profiles. By designing the roof, side walls, chassis, and end walls as being welded from large, hollow, double-surfaced extruded aluminum alloy profiles, the design of the body structure is greatly simplified, while simultaneously improving its strength.

[0004] However, this technology does not address the technical issues and solutions of this application. Utility Model Content

[0017] The straddle-type monorail transit vehicle body structure of this utility model is based on a modular design, with separate underframe modules, side wall modules, roof modules, and end wall modules. The underframe module is made of high-strength carbon steel plate, while the side wall modules and roof modules are made of hollow aluminum alloy profiles. This design ensures good strength for the underframe module and significantly reduces the weight of the vehicle body while effectively maintaining its strength. The underframe module has a frame structure, and multiple side wall modules are included.

[0030] The following description, with reference to the accompanying drawings, provides a more detailed explanation of the specific embodiments of this utility model, including the shape and structure of each component, the relative positions and connections between the parts, the functions and working principles of each part:

[0031] As attached Figure 1 - Appendix Figure 10As shown, this utility model is a straddle-type monorail transit vehicle body structure. A side wall module 2 is provided on each side of the underframe module 1. The bottom of each side wall module 2 is connected to the corresponding side of the underframe module 1 via rivets 7, and the upper part of each side wall module 2 is connected to the corresponding side of the roof module 3 via rivets 7. End wall modules 4 are provided near the front and rear of the underframe module 1, respectively. Each end wall module 4 is connected to the underframe module 1, side wall modules 2, and roof module 3 via rivets 7. To address the shortcomings of the prior art, an improved technical solution is proposed. In the structural design, based on the modular concept, the underframe module 1, side wall modules 2, roof module 3, and end wall modules 4 are manufactured separately. The underframe module uses high-strength carbon steel plate, while the side wall modules and roof modules are made of hollow aluminum alloy profiles. This ensures good strength for the underframe module and significantly reduces the weight of the vehicle body while effectively guaranteeing its strength. The underframe module 1 is a frame structure, and multiple side wall modules are included. The underframe module 1, side wall modules 2, roof module 3, and end wall modules 4 are then connected using riveting. Specifically, each side of the underframe module 1 has a side wall module 2. The bottom of each side wall module 2 is connected to the corresponding side of the underframe module 1 via rivets 7, and the upper part of each side wall module 2 is connected to the corresponding side of the roof module 3 via rivets 7. End wall modules 4 are located near the front and rear of the underframe module 1, and each end wall module 4 is connected to the underframe module 1, side wall modules 2, and roof module 3 via rivets 7.

[0035] The roof module 3 is configured as a structure welded from multiple hollow aluminum profiles 31. In this structure, the roof module is supported by aluminum alloy profiles, resulting in a lightweight overall design.

[0036] The side wall module 2 is constructed from welded hollow aluminum profiles.

This structure gives the vehicle body structure advantages such as sound insulation, noise reduction, and good water tightness.

[0038] The end wall module 4 is a structure made of aluminum alloy sheet. With the top module and end wall module 4 supported by aluminum alloy sheet material, the overall structure is lightweight, achieving weight reduction.

[0039] The bottom of the multiple crossbeams 11 of the base frame module 1 is welded with stainless steel plates 12. This structure, with the stainless steel plates 12 welded to the bottom of the multiple crossbeams 11, improves the overall strength of the base frame module.

[0040] The straddle-type monorail transit vehicle body structure of this utility model is based on a modular design, with separate components including a base frame module 1, side wall modules 2, roof modules 3, and end wall modules 4. The base frame module is made of high-strength carbon steel plate, while the side wall modules and roof modules are made of hollow aluminum alloy profiles. This design ensures good strength for the base frame module and significantly reduces the weight of the vehicle body while effectively maintaining its strength. The base frame module 1 is a frame structure, and the side wall modules consist of multiple components. The base frame module 1, side wall modules 2, roof modules 3, and end wall modules 4 are then connected using riveting. Specifically, each side of the chassis module 1 is provided with a side wall module 2.
