Abstract

The invention discloses a carriage chassis, a carriage assembly comprising the carriage chassis and a railway self-dumping wagon, the carriage chassis comprises a bearing frame, the bearing frame is formed by at least two cross beams and at least two side beams in an enclosing mode, and a floor is arranged on the frame formed by the cross beams and the side beams in an enclosing mode; at least two outer rotating shaft mechanisms are arranged at the bottom of the bearing frame, at least two inner rotating shaft mechanisms are arranged between the outer rotating shaft mechanisms, and at least one upper limiting stop assembly used for being matched with the underframe assembly is arranged between the inner rotating shaft mechanisms so as to limit the carriage underframe in the longitudinal direction and the transverse direction. Flying dust, raining, stealing and the like of cargoes carried in the carriage can be prevented, the overall structural strength and rigidity of the carriage can be enhanced, meanwhile, the self weight of a vehicle is reduced, and the load of the vehicle is increased.

Description

technical field [0001] The invention relates to the technical field of railway self-rollover vehicles, in particular to a carriage chassis, a carriage composition including the carriage chassis, and a railway self-turnover vehicle. Background technique [0002] The existing railway self-rolling vehicles have a large dead weight, weak overall strength and rigidity of the carriages, insufficient anti-overturning stability during dumping and unloading operations, high costs in product manufacturing and use, excessive daily maintenance workload of the vehicles, and During the process, problems such as dust and theft occurred. Each of the existing railway self-dumping cars is equipped with unloading equipment, and the weight of the unloading equipment for each self-dipping car is usually greater than 2.1t. Since the unloading equipment of the railway self-dumping car is only used during the self-dipping operation, the unloading equipment is not needed in other working conditions...
