Description

technical field

[0001] The invention relates to the field of low-floor trams, in particular to an end beam and a lower hinged mounting seat structure of a low-floor tram. 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. [0003...
