The invention provides a vehicle hinge device, a vehicle chassis and a vehicle. The vehicle hinge device comprises a hinge seat, a mounting seat suitable for being mounted at one end of a chassis of the vehicle, and provided with the hinge seat, and a reinforcing seat arranged between the mounting seat and the chassis so as to transfer the stress of the hinge seat to the chassis and / or the vehicle body. According to the vehicle hinge device, the mounting seat is arranged at one end of the vehicle chassis, the hinge seat can be directly mounted on the mounting base, and then vehicle hinging can be achieved. The reinforcing seat is arranged between the mounting seat and the bottom frame, so that when the hinge seat is longitudinally compressed and stretched, longitudinal stress can be transmitted to the bottom frame through the reinforcing seat; when the hinge seat is subjected to a vertical load, the vertical stress can be transmitted to the vehicle body through the reinforcing seat. In this way, the bearing capacity of the vehicle hinge device can be improved, and the safety performance of the vehicle is improved. In addition, the vehicle hinge device further has the advantages of being simple in structure, high in reliability, convenient to maintain and the like.
Description
technical field [0001] The present invention relates to the technical field of vehicle equipment, and in particular, to a vehicle hinge device, a vehicle chassis and a vehicle. Background technique [0002] In the related art, articulated vehicles are mostly found in low-floor trams. This type of articulated vehicle is roughly divided into the following three types: one is fixed hinge, that is, the two adjacent vehicle underframes are only connected by a fixed hinge device; the other is the connection at both ends, also That is, the bogies of two adjacent vehicles are provided with core plates connected to the vehicle bodies, the two vehicle underframes are individually connected to the two core plates of the bogies, and there is no hinge device between the vehicle bodies; the other is In the middle hinge structure, that is, two adjacent vehicle underframes are connected by a hinge device, and then the hinge device is connected with the bolster in the bogie through a center...
