Abstract

The invention discloses a floating car body for a 100% low-floor tramcar and an assembling method of the floating car body. The floating car body comprises a car roof, a side wall, an end wall, a floor, a front underframe end and an upper articulated mounting base, which are riveted into one body; no bogie is arranged under the floating car body and two ends of the floating car body are connected with a motor car and a trailer by articulated devices; the front underframe end and the upper articulated mounting base are steel plate welding assemblies, and the car roof, the side wall, the end wall and the floor are formed by aluminum alloy sections or aluminum alloy panels through assembling and welding. According to the floating car body for the 100% low-floor tramcar, the entry height of a car door can be effectively reduced due to no limitation of the bogie, and besides, a bench seat can be longitudinally arranged, so that a space inside the car is large and the passenger capacity is effectively increased. The floating car body for the 100% low-floor tramcar has the remarkable advantages of simple structure, convenience in assembly, reliability in performance, good repairability and the like.

Description

technical field

[0001] The patent of the present invention belongs to the technical field of tramcars, and specifically relates to a car body assembly method and an assembly method using riveting instead of welding. Background technique

[0002] 100% low-floor tram is one of the important tools of modern urban rail transit. It is popular in cities for its convenience for passengers, diverse marshalling, flexible operation, and sharing of existing bus stops and road resources. As the load-bearing part of 100% low-floor vehicles, the tram body is the key component to achieve low-floor. Since the low-floor vehicles and trailers are equipped with bogies, the car body is limited by the bogies, and the entrance height of the door cannot be effectively reduced, thereby affecting the space in the car and limiting the passenger capacity, while the low-floor tram floats The car body is a load-bearing part of a 100% low-floor vehicle. Since there is no bogie under it, the height of th...
