Hinged mounting base on 100% modern city tramcar

Abstract

The invention discloses a hinged mounting base on a 100% modern city tramcar. The hinged mounting base comprises an upper panel, a lower panel, a connecting rib plate, a rear block plate and a base, wherein the connecting rib plate is respectively connected to the upper panel, the lower panel and the rear block plate in a welding manner; the upper panel and the lower panel are welded on the rear block plate; the rear block plate is welded on the base; a hole for riveting is formed in the base. The hinged mounting base can be applied to installation of an upper hinge device of a 100% low-floor tramcar. The connection mode of the hinged mounting base and a car body is a riveting manner, so that not only is the hinged mounting base not limited by a roof end part material, but also the hinged mounting base can be conveniently repaired and replaced after being damaged. The hinged mounting base is welded by a high-strength carbon steel material, so that the hinged mounting base has enough strength and rigidity, and is especially applicable to local reinforcement on the hinged part on an aluminum alloy car body, the strength index of the overall car body is met, the weight of the car body is reduced, and the hinged mounting base has significant advantages of simple structure, reliable performance, good repairability and the like, and is convenient to assemble.

Description

technical field [0001] The invention belongs to the technical field of tramcars, in particular to an upper hinged mounting seat for connecting tramcar bodies. Background technique [0002] Low-floor trams are one of the important tools of modern urban rail transit. They are popular among cities for their convenience for passengers, diverse marshalling, flexible operation, and sharing of existing bus stops and road resources. Low-floor trams The car body is the load-bearing part of the low-floor vehicle, and the upper hinged mount on it plays a key part in connecting the two cars and sharing the weight of the floating car. [0003] The material of the upper articulated mounting seat of existing low-floor trams at home and abroad is the same as that of the car body, that is, the carbon steel car body is matched with the upper twisted mounting seat of carbon steel material, and the aluminum alloy car body is matched with the upper twisted mounting seat of aluminum alloy materia...

AI Technical Summary

Problems solved by technology

[0003] The material of the upper articulated mounting seat of existing low-floor trams at home and abroad is the same as that of the car body, that is, the carbon steel car body is matched with the upper twisted mounting seat of carbon steel material, and the aluminum alloy car body is matched with the upper twisted mounting seat of aluminum alloy material. Seats, which are connected to the car body by welding, are irreparable and irreplaceable

At the same time, there is no shock absorber in the installation position of the upper winch of existing low-floor trams at home and abroad, and the upper hinged mounting seat only has the function of installing the upper winch
