Example Embodiment

[0032] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0033] This embodiment provides a train bogie, such as Figure 1-4 Shown. among them, figure 1 It is a schematic structural diagram of a specific embodiment of the bogie frame provided by the present invention; figure 2 for figure 1 Partial enlarged view of; image 3 Exploded diagrams of beams and small longitudinal beams; Figure 4 Is a structural diagram of the gear box hanger 3;

[0034] The bogie includes a frame 1 which includes two ...

Abstract

The invention provides a bogie comprising a frame. The frame comprises two parallelly-arranged side beams, end beams perpendicularly connected between the two side beams and crossbeams arranged between the two side beams. Small longitudinal beams composed by splicing a plurality of plates are arranged between the crossbeams; the interior of each small longitudinal beam is of a hollow structure, and one ends of the small longitudinal beams extend to the outer sides of the crossbeams. According to the small longitudinal beams of the hollow structures, the weight of the bogie is reduced while the overall structural strength of the bogie is guaranteed, and rainwater and the like are also prevented from invading inner cavities of the small longitudinal beams to corrode internal structures; one ends of the small longitudinal beams extend to the outer sides of the crossbeams, on the one hand, the stiffness and strength of a main structure of the frame can be improved, and the welding contact area of the small longitudinal beams with the crossbeams is increased; and on the other hand, the situation that the ends, extending out of the crossbeams, of the small longitudinal beams are connected to other parts such as a gear box hanger and a motor hanger is facilitated, in this way, the structures of the other parts are simplified, the operation space of part mounting is enlarged, and mounting is convenient. On this basis, the invention further provides a railway train.

Description

technical field [0001] The invention relates to the technical field of rail vehicles, in particular to a bogie and a rail vehicle with the bogie. Background technique [0002] With the popularity of high-speed rail, people have put forward higher and higher requirements for the ride comfort of high-speed rail. High-speed rail engineers have put forward higher requirements for the manufacturing process of trains on the basis of meeting the needs of passengers. [0003] The bogie is the main component of the train, and it is the direct bearer of the vehicle traction force, braking force, vehicle load and external force on the track, and plays a vital role in the running quality of the vehicle and the safety of passenger transportation. The small longitudinal beam on the bogie is an important part of the bogie. Motors and gear boxes are also arranged on the small longitudinal beam. Not only that, the small longitudinal beam also shoulders the function of the stop. Whenever the...
