Embodiment Construction

[0025] All features disclosed in this specification, or steps in all methods or processes disclosed, may be combined in any manner, except for mutually exclusive features and / or steps.

[0026] A 100% low-floor tram car body is a mixed steel-aluminum riveted car body, including a trailer, including 1 chassis, 2 end walls, 3 roofs, and 4 side walls. It has a simple structure, light weight, and convenient assembly in different places. Reliable performance and strong repairability. The four modules 1 underframe, 2 end walls, 3 roof and 4 side walls are riveted to form a frame structure, the overall strength and rigidity of the car body are guaranteed and the process difficulty of car body assembly is reduced; when one of the modules is damaged , this part can be replaced separately; the off-site factory can easily realize the separate transportation of the four modules, and the off-site quick integration reduces transportation costs and improves work efficiency.

Abstract

The invention discloses a 100% low-floor tramcar trailer body and an assembling method thereof. The trailer body comprises a bottom frame, an end wall, a roof and a sidewall; the sidewall is riveted with the roof and the bottom frame; the end wall is riveted with the roof and the bottom frame; the end wall is riveted with the sidewall. The 100% low-floor tramcar trailer body is simple in structure, light in weight, convenient and quick to assemble at different places, reliable in performance, and high in repairability; four modules, namely, the bottom frame module, the end wall module, the roof module and the side wall module are riveted to form a frame structure, thus the overall intensity and rigidity of the trailer body are ensured, and the difficulty of trailer body assembling process is lowered down; any damaged module can be replaced individually; the four modules can be individually easily transported for plant at different place, and the four modules can also be quickly integrated at different places, thus the transportation cost is decreased, and the working efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of tramcars, and in particular relates to a vehicle body assembly method in which riveting is used instead of welding. Background technique [0002] The modules of the tram body at home and abroad are mostly connected by welding. The welding process and quality control process are very complicated, and the corresponding capital investment is also relatively high. The underframe of the car body described in this patent is a steel structure module, and the rest are aluminum alloy modules, and each module is assembled through a riveting process. This not only reduces the weight of the car body, but also satisfies the strength and rigidity of the whole vehicle, which has great advantages especially when the car body is assembled in different places. Contents of the invention [0003] The object of the present invention is to solve the above problems, and to provide a riveting relationship between modules of a...
