Abstract

A railcar pivotal connection apparatus and a tram. The pivotal connection apparatus (100) comprises a connecting component (10) and a mounting part (20). The connecting component (10) is connected respectively to one end of the mounting part (20) and to a top part of a first railcar (30) or a last railcar (40). The other end of the mounting part (20) is used for connecting to a pivotal connection apparatus (50) connected to the top part of the railcar adjacent to the first railcar (30) or the last railcar (40). Moreover, the end surface of the end of the mounting part (20) connected to the pivotal connection apparatus (50) is an inclined surface (21). A fixed angle is provided between the inclined surface (21) and a connecting surface of the pivotal connection apparatus (50). With the end surface of the end of the mounting part (20) connected to the pivotal connection apparatus (50) being provided as the inclined surface (21), and tail parts of the first railcar (30) and of the last railcar (40) being jacked up when joined, the inclined surface (21) becomes perpendicular to the ground and connects with the pivotal connection apparatus (50), the railcar forms an upward arched bridge shape when mounted, and the entire vehicle is provided with a fixed pre-deflection, thus solving the problem in which the vehicle deflection is distended by an increase in passenger capacity that results in an axle weight deviation, which affects normal operations of the vehicle.

Description

Technical field [0001] The invention relates to a transportation vehicle, in particular to an articulated connection device for carriages and a tram. Background technique [0002] As a medium-capacity transportation tool, trams can fill the gap between bus and subway transportation. Its length is shorter and it is more convenient and flexible to run on existing urban roads. It is especially suitable for small and medium-sized cities. Main line traffic and branch line traffic in big cities, modern trams have the advantages of convenience, speed, safety and comfort, energy saving and environmental protection, low investment cost, short construction period, and strong adaptability to the urban environment. They are veritable "green vehicles". [0003] A tram is usually provided with multiple carriages, and adjacent carriages are respectively connected with an articulation device through an articulated connecting seat, thereby splicing the carriages together. Take a three-carriage tra...
