Abstract

The invention discloses a low-floor tramcar floating car end beam and lower part hinged mounting base structure. The low-floor tramcar floating car end beam and lower part hinged mounting base structure comprises an end beam and a hinged mounted base arranged at the center of the back end of the end beam; two bilaterally symmetrical workshop damping mounting bases are arranged on the end beam; bilaterally symmetrical rotary stops are arranged on the two sides of the hinged mounting base; the end beam is formed by welding a main sectional material and a secondary sectional material front and back; the main sectional material and the secondary sectional material have hollow structures; rib plates capable of improving rigidity and strength are arranged in the main sectional material and the secondary sectional material; the internal part of the hinged mounting base is trapezoidal hollow; and the trapezoidal hollow internal part is provided with a reinforcing rib. The low-floor tramcar floating car end beam and lower part hinged mounting base structure is high in strength performance, simple in structure, convenient to manufacture and maintain and low in cost, and guarantees the lightweight design of the structure on the premise of meeting the bearing capacity; and through the arrangement form of the unique end beam, the hinged mounting base, the rotary stops and the workshop damping mounting bases, the requirement on vehicle operating stability and comfortability is met.

Description

technical field

[0001] The invention relates to the field of low-floor trams, in particular to a low-floor tram floating car end beam and a lower hinged mounting seat structure. Background technique

[0002] Modern low-floor trams adopt the design scheme of short car body modules in order to meet the requirements of passing through small-radius curves, and the modules are connected by hinge mechanisms. The end beam and the hinged mounting seat need to bear the longitudinal force, lateral force, vertical force and corresponding torsional load generated during the operation of the vehicle, and transmit the above force to another vehicle through the hinge mechanism. At the same time, by constraining and releasing the degree of freedom between the vehicle modules, the vehicle can pass through the small radius curve smoothly and quickly to ensure the smooth running of the vehicle. Therefore, the end beam and the hinged mounting seat are the key components of the low-floor tram. ...
