Abstract

The invention provides a tramcar. The tramcar comprises at least two carriages, wherein a carriage hinging device is arranged between every two adjacent carriages; each carriage hinging device comprises a bearing framework, a lower hinging assembly, an upper hinging assembly and a vestibule windshield; each lower hinging assembly comprises a first joint bearing, a second joint bearing, a first connecting plate and a second connecting plate; each connecting plate is hinged to the corresponding bearing framework through the corresponding joint bearing; an upper mounting shaft is arranged at the upper part of each bearing framework; a rubber bearing is arrange on each upper mounting shaft; each upper hinging assembly comprises two first connecting rods, a second connecting rod, first mounting bases and two second mounting bases; one end part of each first connecting rod is hinged to the corresponding bearing framework through the corresponding rubber bearing; the other end part of each first connecting rod is hinged to the corresponding first mounting base through a third joint bearing; two ends of each second connecting rod are hinged between the two second mounting bases through fourth joint bearings; and one second mounting base is fixed at the upper part of the corresponding bearing framework. The reliability of the tramcar is improved.

Description

technical field [0001] The invention relates to traffic vehicles, in particular to a tram. Background technique [0002] Tram is a common means of transportation for people’s daily travel. Tram is usually provided with multiple carriages, and two adjacent carriages are connected by hinged joints. Chinese Patent No. 971967709 discloses a relative transportation vehicle separated by an intermediate Composite hinged joints for adjacent carriages. The above-mentioned patent discloses that two adjacent carriages are hinged through the middle cabin, and the middle cabin has two hinge joints to respectively hinge the corresponding carriages. The longitudinal and lateral loads between the two carriages need to be Mutual transfer through the middle compartment, in the actual use process, the middle compartment and the hinged joints on the middle compartment bear the longitudinal force and lateral force exerted by the carriage on the one hand, and also bear the vertical force exerted ...
