Abstract

The invention provides a heavy-duty frame-type bearing chassis and a railway vehicle. The heavy-duty frame-type bearing chassis comprises two crossbeams and two longitudinal beams, the two longitudinal beams are connected between the two crossbeams, cross sections of the crossbeams are of box-shaped structures, cross sections of the longitudinal beams are of step structures, and the two longitudinal beams are arranged oppositely. The heavy-duty frame-type bearing chassis has the advantages of high strength, good rigidity, simple and compact structure and small in occupied space, a convenient space is provided for mounting of a common chassis of units, the weight of a chassis of a rail vehicle is lowered, and space utilization rate is increased.

Description

[0001] technical field [0002] The invention relates to the field of rail transportation, in particular to a heavy-duty frame-type bearing chassis and a rail vehicle. [0003] Background technique [0004] At present, rail vehicles are widely used in the industrial transportation industry. The chassis of rail vehicles usually includes two beams and two longitudinal beams, and the two longitudinal beams are connected between the two beams. In order to enhance the structural strength of the chassis, a middle beam is usually added between the two beams. structure, the center sill structure can effectively strengthen the longitudinal bearing capacity of the car body, but because the center sill must run through the entire length of the car, the longitudinal span is large, it will increase the weight of the car body, and occupy the space of the underframe, resulting in the bottom of the rail vehicle in the prior art The rack is heavy and the space utilization rate is low.
