Embodiment 1

[0044] figure 2 A structural diagram of a loading device for testing the bearing capacity of a bogie frame shown in an exemplary embodiment of the present invention.

[0045] like figure 2 As shown, the loading device 10 for testing the bearing capacity of the bogie frame provided by this embodiment includes:

[0046] The loading part 1 is used to apply external force to the bogie frame to be tested, the connecting part 2 is used to transmit the external force to the bogie frame, and the first ball joint 3 is used to adjust the application angle of the external force.

[0047] The first end 11 of the loading member 1 is connected to the connecting member 2 through the first ball joint 3 .

[0048] Wherein, the first end 11 of the loading member 1 is connected with the first ball hinge 3 through a connecting device, and the first ball hinge 3 is connected with the connecting part 2 through a connecting device, and the connecting device can be a bolt, a support member and the ...

Embodiment 2

[0061] image 3 Another exemplary embodiment of the present invention is a structural diagram of a loading device for testing the bearing capacity of a bogie frame.

[0062] like image 3 As shown, on the basis of Embodiment 1, the loading device provided by this embodiment also includes a support base 4, the support base 4 is connected to the second end 12 of the loading member 1 through the second ball joint 5, and the support base 4 is used for For fixed loading parts.

[0063] Specifically, the connection through the second ball joint 5 means that the support seat 4, the second ball joint 5, the loading part 1, the first ball joint 3, and the connecting part 2 are sequentially connected. Wherein, through the connection of the second ball joint 5, one end of the second ball joint 5 can be fixed on the support base 4, and the other end is connected with the second end 12 of the loading part 1. When the bogie frame is subjected to an external force, the force will Through ...

Embodiment 3

[0068] For the convenience of the directions mentioned in this embodiment and the following embodiments, the direction parallel to the beam of the bogie frame is determined as the transverse direction (Y), the direction parallel to the side beam is determined as the longitudinal direction (X), and the direction perpendicular to the side beam is determined as the longitudinal direction (X). The directions of the transverse (Y) and longitudinal (X) directions are determined as vertical (Z). Wherein, the longitudinal direction (X) is the moving direction of the vehicle on which the bogie frame is installed. It should be noted. The above description of directions is only for clearly describing the positional relationship of the components in the embodiments of the present invention, and is not intended to limit the present invention.

[0069] This embodiment also provides a loading device for testing the bearing capacity of the bogie frame in the first direction. On the basis of ...

Abstract

The invention provides a loading device and a testing system for testing the carrying capacity of a bogie. The loading device comprises a loading component, a connecting component and a first spherical hinge; the loading component is used for applying an external force to a bogie to be tested; the connecting component is used for transferring the external force to the bogie; the first spherical hinge is used for adjusting the application angle of the external force; the first end of the loading component is connected with the connecting component through the first spherical hinge; and the connecting component is connected with the bogie so as to enable the external force which is applied by the loading component and has been subjected to the angle adjustment of the first spherical hinge toact on the structure of the bogie. The loading component is connected with the connecting component through the spherical hinge component, so that a force generated by the loading component can be transferred along the connection line of the spherical hinge component and the connecting component, and forces in other directions can be released, and therefore, the transfer direction of the force generated by the loading component can be locked, and the technical problem of unnecessary damage to the bogie caused by a condition that the structure of the bogie bears the forces in the other directions can be prevented.

Description

technical field [0001] The invention relates to mechanical equipment detection technology, in particular to a loading device and a testing system for testing the bearing capacity of a bogie frame, belonging to the field of machinery. Background technique [0002] The bogie is one of the most important components of a rail vehicle. It is used to support the car body and ensure the normal operation of the vehicle. Whether the structure of the bogie is reasonable will directly affect the comfort, stability, power performance and driving safety of the vehicle during operation. . A bogie includes a frame. like figure 1 As shown, the frame 1 includes side beams 101, cross beams 102 and longitudinal beams 103, two side beams 101 and two cross beams 102 are welded into an "H" shape structure, wherein the height of the side beams 101 is lowered in the middle for installing air Springs, side beams 101 are also used for welding primary and secondary spring seats, shock absorber seat...
