Embodiment Construction

[0029] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0030] As described in the background technology, the cast steel three-piece bogie has low rigidity against rhomboid deformation, is prone to rhomboid deformation, and is prone to misalignment of the two side frames. When it is in the normal position, the oblique wedge is in close contact with the side frame and the bolster. After dislocation, the oblique wedge rotates, and the two oblique wedges are also dislocated, which affects the normal operation of the bogie.

[0031] To solve the above problems, see figure 1 As shown, the present invention provides a bogie, the bogie in this embodiment includes two side frames 10 and a bolster 20 arranged between the two side frames 10, the bogie also i...

Abstract

The invention provides a bogie and a railway vehicle with the bogie. The bogie includes two side frames and a swing bolster arranged between the two side frames, the bogie further includes a support part, the two ends of the support part are connected with the side frames respectively, and the support part is parallel to the swing bolster. Since the bogie includes the support part, the two ends ofthe support part are connected with the two side frames respectively and the support part is parallel to the swing bolster, when the bogie is subjected to external force, the support part can supportthe two side frames, thus the diamond-resistant rigidity of the bogie is effectively improved, and occurrence of diamond deform is prevented; meanwhile, the support part is parallel to the swing bolster, the inside space of the bogie is reasonably used, the support part does not need to pass through the swing bolster and is not located below the swing bolster, the design of the swing bolster is not affected, the situation that the swing bolster contains the support part, opening thus is needed and the strength of the swing bolster is reduced is avoided, and it is convenient for workers to install the bogie.

Description

technical field [0001] The invention relates to the technical field of bogies, in particular, to a bogie and a rail vehicle with the bogie. Background technique [0002] Railway freight cars of wheel-rail vehicles are generally composed of car body, bogie, brake device, coupler buffer device and other parts. Among them, the function of the bogie is to support the car body, guide the vehicle to run along the track, and bear various loads from the car body and the line. The most common bogie on a railway freight car is a cast steel three-piece two-axle bogie, which consists of a bolster, two side frames, two wheelsets, a spring damping device and a braking device. [0003] According to relevant theories, the low anti-diamond stiffness of the bogie will lead to low critical speed of the vehicle. The cast steel three-piece bogie has low rigidity against rhomboid deformation, and is prone to rhomboid deformation, and the two side frames are prone to misalignment. When it is in...
