A 100% modern urban tram upper articulated mount

Abstract

The invention discloses a 100% modern city tram upper hinged installation seat, which comprises an upper panel, a lower panel, a connecting rib plate, a rear blocking plate, and a base. The connecting rib plate is respectively connected to the upper panel, the lower panel by welding. The panel and the rear blocking plate, the upper panel and the lower panel are welded on the rear blocking plate, the rear blocking plate is welded on the base, and the base is provided with holes for riveting. The present invention can be used for the installation of the upper articulated device of 100% low-floor trams. Since it is connected to the car body by riveting, it is not limited by the material of the top of the car, and it is easy to repair and replace after it is damaged; Welded with high-strength carbon steel material, it has sufficient strength and rigidity, especially suitable for local reinforcement of the upper hinge of the aluminum alloy car body, which not only meets the strength index of the whole vehicle, but also reduces the weight of the car body. The device has obvious advantages such as simple structure, convenient assembly, reliable performance and good repairability.

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
