Problems solved by technology

The bolster of this structure is unreasonable from the perspective of bearing the vertical force, and in order to ensure the strength, the thickness of the side wall of the bolster must be increased, so that the weight of the bolster will increase a lot, which is not conducive to reducing the self-weight

Embodiment 1

[0019] image 3 It is a schematic structural diagram of a bogie link support device provided in Embodiment 1 of the present invention. The bogie link support device includes a rigid connecting body 40 and four connecting rods 10 . The shape of the rigid connecting body 40 is ring-shaped; four connecting rods 10 are respectively arranged on both sides of the rigid connecting body 40, and the two connecting rods 10 on the same side are respectively pivotally connected to the rigid connecting body 40 to form a U-shaped linkage mechanism , the four pivot axes are all along the vertical direction.

[0020] When the bogie connecting rod supporting device provided in this embodiment is arranged on the bogie, the four connecting rods are respectively fixed on the two side frames to realize the effect of anti-diamond deformation. The connection between the connecting rod and the rigid connecting body is a flexible connection, which can be a round pin connection, or other forms of pivo...

Embodiment 2

[0026] Figure 5 The structure schematic diagram of the bogie connecting rod supporting device provided on the upper part of the bolster provided by the second embodiment of the present invention. In this embodiment, the connecting rod supporting device is arranged above the bolster 20 and the annular rigid connecting body 40 is sleeved on The outer side of the heart plate 22 of the bolster 20 . When arranged above, the rigid connecting body 40 preferably adopts a circular shape, matching the shape of the core disc 22 .

[0027] The bogie link support device provided by this embodiment can be sleeved on the outside of the center plate of the bolster because the rigid connecting body is ring-shaped, and can cooperate well with the structure of the bolster itself, which can effectively save space. In actual use, the bogie link support device can also be arranged under the bolster, which can also play a good role in anti-rhombic deformation.

Abstract

The invention provides a supporting device of a connecting rod of a bogie, a bogie and a truck. The supporting device comprises a rigid connecting body and four connecting rods. The shape of the rigid connecting body is annular; four connecting rods are arranged on two sides of the rigid connecting body respectively; two connecting rods on the same side are pivoted on the rigid connecting body respectively to form a U-shaped connecting rod mechanism; and four pivoting axes are in the vertical direction. Because the rigid connecting body is annular, the supporting device of the connecting rod of the bogie, the bogie and the truck, provided by the invention, can be sleeved on the outer side of a centre plate of a swing bolster, or can cooperate with a swing bolster structure well after passing through preformed holes on two sides in the middle of the swing bolster, so as to ensure the strength of the swing bolster.

Description

technical field [0001] The invention relates to bogie mechanical structure technology, in particular to a bogie connecting rod support device, bogie and freight car. Background technique [0002] At present, the most common bogies on railway freight cars are three-piece two-axle bogies, including bolsters, side frames and wheelsets. The car body and its load act on the bogie through the bolster center plate, and turn through the curve between the upper and lower center plates. However, the three-piece two-axle bogie has a low rhombic stiffness because the connection between the side frame and the bolster is only through the shock absorber. As the shock absorber wears out, the side frame is prone to "rhombic misalignment". The "diamond misalignment" of the side frame of the bogie will reduce the critical speed of the vehicle's serpentine motion, thereby reducing the running stability and increasing the wear of the wheel and rail. When the vehicle runs on the railway curve, ...
