The following description of at least one exemplary embodiment is merely exemplary in nature and is in no way intended to limit the utility model, its application, or uses. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

As shown in fig. 1 to 3, the embodiment of the present utility model provides a bogie comprising a side frame 10, a bolster 20, and a cam 30, the side frame 10 extending in a lateral direction, the side frame 10 having a mounting hole extending in a longitudinal direction and penetrating therethrough; the swing bolster 20 extends longitudinally, one end of the swing bolster 20 is inserted into the mounting hole, a planar structure 21 is arranged on the side wall of the first side of the swing bolster 20, and the first side of the swing bolster 20 is in friction fit with the hole wall of the mounting hole through the planar structure 21; wedge 30 is disposed between side frame 10 and a second side of bolster 20, and has ramp structure 22 on a sidewall of the second side of bolster 20, the second side of bolster 20 being in friction fit with the first side of wedge 30 via ramp structure 22, and the second side of wedge 30 being in friction fit with side frame 10.

By applying the technical scheme of the utility model, the bogie comprises a side frame 10, a swing bolster 20 and a wedge 30, one end of the swing bolster 20 is inserted into a mounting hole of the side frame 10, a plane structure 21 on the side wall of the first side of the swing bolster 20 is in friction fit with the hole wall of the mounting hole, a bevel structure 22 on the side wall of the second side of the swing bolster 20 is in friction fit with the first side of the wedge 30, and the second side of the wedge 30 is in friction fit with the side frame 10. Compared with the prior art, the two sides of the swing bolster 20 are in friction fit with the side frames 10 through the inclined wedges 30, and the bogie is adopted, so that the number of the inclined wedges 30 is reduced on the premise of improving the running speed of the bogie, and the manufacturing and maintenance cost is reduced.

In the related art, since both sides of the bolster 20 are friction-fitted with the side frames 10 through the wedges 30, a gap must be present between the bolster 20 and both wedges 30 in order to ensure assembly and operation requirements, which reduces the anti-diamond rigidity of the bogie and reduces the running speed of the bogie. By adopting the bogie provided by the embodiment, as the number of the inclined wedges 30 is reduced, the gap between the swing bolster 20 and the side frame 10 in operation can be reduced, and the diamond resistance rigidity of the bogie can be effectively improved, so that the operation speed of the bogie is improved.

As shown in fig. 2 and 3, a first abrasion plate 211 is disposed on the planar structure 21, a second abrasion plate 221 is disposed on the inclined surface structure 22, a side frame abrasion plate is disposed on the wall of the mounting hole, the first abrasion plate 211 is in friction fit with the corresponding side frame abrasion plate, and the second abrasion plate 221 is in friction fit with the inclined wedge 30. The use of the first wear plate 211 and the second wear plate 221 increases the friction between the bolster 20 and the side frame 10, extending the service and maintenance time.

In this embodiment, the second side of wedge 30 is friction fit with side frame 10 via a wear plate.

As shown in fig. 2 and 3, two first wear plates 211 are provided on the planar structure 21, the two first wear plates 211 are disposed at intervals in the longitudinal direction, and two second wear plates 221 are provided on the inclined structure 22, the two second wear plates 221 are disposed at intervals in the longitudinal direction.

In this embodiment, the first wear plate 211, the second wear plate 221, and the side frame wear plates are all made of metal material and heat treated to have sufficient hardness to reduce wear during operation.

As shown in fig. 2, two first stoppers 23 are disposed on the side wall of the first side of the swing bolster 20, the two first stoppers 23 are disposed at intervals along the longitudinal direction, the two first stoppers 23 are respectively located at two sides of the side frame 10, two first wear plates 211 are located between the two first stoppers 23, each first wear plate 211 is in clearance fit with a corresponding first stopper 23, and by using the two first stoppers 23, a limiting effect can be formed on the side frame 10, so that the bogie is in a stable working state, and meanwhile, the two first wear plates 211 are disposed as close to the first stoppers 23 as possible, so that the diamond resistance of the bogie can be further improved.

As shown in fig. 3, two second stoppers 24 are disposed on a sidewall of the second side of the bolster 20, the two second stoppers 24 are disposed at intervals along the longitudinal direction, the two second stoppers 24 are respectively disposed at both sides of the side frame 10, and two second wear plates 221 are disposed between the two second stoppers 24, and each second wear plate 221 is in clearance fit with the corresponding second stopper 24. With two second stops 24, a limiting effect can be formed on the side frame 10 to bring the bogie into a stable working state, and at the same time, the two second wear plates 221 are arranged as close to the second stops 24 as possible, so that the diamond resistance of the bogie can be further improved.

As shown in fig. 3, the surface height dimension of the second wear plates 221 gradually increases in the direction in which the two second wear plates 221 are away from each other. By adopting the structure, the anti-diamond rigidity of the bogie can be improved so as to improve the running speed of the bogie.

In the first embodiment of the present application, the second side of the swing bolster 20 is provided with the avoidance groove 25, the groove bottom of the avoidance groove 25 forms the inclined surface structure 22, in the direction from top to bottom, the distance between the groove bottom of the avoidance groove 25 and the notch thereof is gradually increased, in the direction in which the two second wear plates 221 are mutually far away, the distance between the groove bottom of the avoidance groove 25 and the notch thereof is gradually reduced, and the second wear plates 221 are flat plates. By adopting the structure, the avoidance groove 25 of the swing bolster 20 is gradually changed in size, and the swing bolster has the advantages of being simple in structure and convenient to process.

In the second embodiment of the present application, the difference between the second embodiment and the first embodiment is that in the second embodiment, in the direction in which the two second wear plates 221 are away from each other, the distance between the groove bottom of the avoidance groove 25 and the notch thereof is unchanged, and the height dimension of the second wear plates 221 is gradually increased. By adopting the structure, the second wearing plate 221 is used for gradually changing the size, and has the advantages of simple structure and convenience in processing.

Of course, the groove bottom of the escape groove 25 and the second wear plate 221 may be configured to gradually change in size in a direction in which the two second wear plates 221 are away from each other.
