Abstract

The invention provides a carriage hinge device and a streetcar. The carriage hinge device comprises a loading frame, a lower hinge assembly and an upper hinge assembly. The lower hinge assembly comprises a first oscillating bearing, a second oscillating bearing, a first connecting plate and a second connecting plate, and the connecting plates are hinged to the loading frame through the oscillating bearings. An upper installing shaft is arranged at the upper portion of the loading frame and provided with a rubber bearing. The upper hinge assembly comprises two first connecting rods, a second connecting rod, two first installing bases and two second installing bases; one ends of the first connecting rods are hinged to the loading frame through the rubber bearing, and the other ends of the first connecting rods are hinged to the first installing bases through a third oscillating bearing; the two ends of the second connecting rod are hinged between the two second installing bases through a fourth oscillating bearing, and one of the second installing bases is fixed to the upper portion of the loading frame. The reliability of the streetcar is improved.

Description

technical field [0001] The invention relates to traffic vehicles, in particular to a carriage hinged device and 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 bea...
