Embodiment 1

[0036] In a typical embodiment of the present invention, such as figure 1 , figure 2 shown. The present invention includes a wheel axle 1, a side beam 2, a frame 3, a side bearing 4, a braking device 5, a bearing saddle 6, and a suspension spring 7;

[0037] The frame 3 is composed of a longitudinal beam and two cross beams, the two cross beams are symmetrically installed on the longitudinal beam, the two cross beams are parallel to each other and perpendicular to the longitudinal beam; the middle part of the longitudinal beam is A concave structure, in which a center disk device is set; on both sides of each beam there is a wheel shaft 1 parallel to it, and the wheel shafts 1 on both sides of the beam are connected together by side beams 2; the side beams The beam 2 is a U-shaped structure with a concave middle part, with guide frames matched with the axle at both ends, and a spring seat in the middle; the frame 3 is loaded on the spring seats of the four side beams throug...

Embodiment 2

[0056] This embodiment discloses a railway freight car. The bogie part of the railway freight car adopts the same structure as that of Embodiment 1, and the structure adopts the existing device.

Abstract

The invention discloses a bogie for a railway wagon with integral low bearing surface and the railway wagon. The bogie comprises side beams and a frame. The frame is composed of a longitudinal beam and two transverse beams, the two transverse beams are symmetrically installed on the longitudinal beam, and the two transverse beams are parallel to each other and perpendicular to the longitudinal beam. The middle part of the longitudinal beam is of a concave structure, and a central disk device is arranged in the concave structure. Axles parallel to the transverse beams are arranged on the two sides of the transverse beams, and the axles positioned on the two sides of the transverse beams are connected together through the side beams. The side beams are of a U-shaped structure with a concavemiddle part, guide frame openings matched with axles are formed in the two ends of the side beams, and spring seats are arranged on the middle parts of the side beams. The frame is supported on the spring seats of the four side beams through four groups of suspension springs.

Description

technical field [0001] The invention relates to a railway vehicle bogie and belongs to the technical field of railway vehicle bogies. Background technique [0002] The statements herein merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] With the rapid development of multimodal transport, it is increasingly urgent to use railway wagons to transport road wagons and semi-trailers as a whole to realize continuous transportation. Railroad wagons for this type of transportation need to have significantly lower load-carrying surfaces than conventional railroad wagons. [0004] The wheel diameter of existing railway freight cars is generally above 840mm, which directly affects the reduction of the height of the vehicle’s load-bearing surface. Due to the limitation of the bogie structure, the current railway freight car adopts a low load-bearing surface in the middle, and the bogie still has a high load-bearin...
