Abstract

The invention discloses a lower hinge device for a rail vehicle and a rail vehicle having the same. The lower hinge device comprises a fixed base; b bearing housing protruding into the fixed housing;a matching bearing matching bearing housing to be arranged in the bear housing; an intermediate shaft which comprises two hollow connecting bodies arranged in the axial direction of the fitting bearing, wherein through holes are arranged on the end faces of the two connecting bodies facing each other and fitting holes are arranged on the end faces away from each other, and each connecting body isrespectively matched with the fitting bearing and the fixing seat; a fastening assembly which passes through the two through holes and cooperates with the two connectors to position the two connectorson the retainer. The lower hinge device of the invention can reduce the mass of the intermediate shaft, is favorable for the overall lightweight of the lower hinge device, simultaneously can reduce the manufacturing cost, and is convenient for dismantling, inspecting, replacing and repairing the lower hinge device.

Description

technical field [0001] The invention relates to the technical field of rail transportation, in particular to a lower hinge device for a rail vehicle and a rail vehicle with the same. Background technique [0002] The lower hinged device in the related art has a large mass, which is not conducive to the lightweight of the overall device, and at the same time, the manufacturing cost is high, and disassembly, replacement and maintenance are inconvenient. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. For this reason, the present invention proposes a lower hinged device for rail vehicles, which can reduce the mass of the intermediate shaft, which is beneficial to the overall weight reduction of the lower hinged device, and can reduce manufacturing costs at the same time, and is convenient for dismantling and inspection of the lower hinged device. replacement and repair. [0004] The pre...
