Embodiment 1

[0055] Such as Figure 1-5 As shown, the wear assembly of the embodiment of the present invention includes a wear block 1 , a wear plate 2 and a transition table 4 . The through channel in the embodiment of the present invention includes a bellows assembly (not shown in the figure) and the wear assembly provided in the embodiment of the present invention. The bellows assembly includes two bellows bodies (not shown in the figure) and the middle connecting frame 3 of the bellows.

[0056] Such as figure 2 and Figure 4 As shown, the transition table 4 includes a friction block 41 . The wear block 1 is U-shaped. Specifically, the longitudinal section of the wear strip 1 is U-shaped, that is, its projection on the longitudinal vertical plane (yOz plane) is U-shaped. The cross-sectional shape of the wear strip 1 , that is, the wear block 1 is U-shaped. The wear block 1 includes two side plates 11 and a bottom plate 12 . Each of the two side plates 11 is provided with three ...

Embodiment 2

[0070] Figure 6-8 Shown is another embodiment of the wear assembly provided by the present invention, the wear assembly is Figure 1-5A modification of the wear assembly (that is, the wear assembly of Embodiment 1 of the present invention), which is the same as Figure 1-5 The wear component distinctions include:

[0071] Such as Figure 7 As shown, the wear block 1 and the friction groove 42 are fixedly connected; preferably, the wear block 1 and the friction groove 42 are integrally formed. Such as Figure 8 As shown, the wear plate 2 and the friction block 41 are fixedly connected; preferably, the wear plate 2 and the friction block 41 are welded or integrally formed. The friction block 41 is located at the center of the wear plate 2 .

[0072] Such as Figure 6 As shown, the inner plane of the friction groove 42 integrated with the wear block 1 is in contact with the top surface of the friction block 41 integrated with the wear plate 2; The outer ring surface of th...

Abstract

The invention provides an abrasion assembly for a rail vehicle through passage. The abrasion assembly comprises an abrasion block, an abrasion plate and a transition table, wherein the top of the abrasion block is adaptably and fixedly connected with a diaphragm assembly of the through passage; the bottom of the abrasion plate is adaptably and fixedly connected with a vehicle hook of a rail vehicle; the transition table is positioned between the abrasion block and the abrasion plate; the abrasion block and the abrasion plate are in contact and are matched through the transition table; the abrasion block can do relative rotation around a fixed axial line relative to the abrasion plate. The abrasion assembly for the rail vehicle through passage provided by the invention has the advantages that when the rail vehicle steers, an abrasion strip and the abrasion plate can freely do relative rotation around the fixed axial line; the transverse deviation friction and rotating position clampingof the abrasion strip and the abrasion plate can be avoided; the great rotation abrasion area is realized; the serious abnormal sound and abrasion due to transverse deviation friction and rotation position clamping can be greatly reduced; the comfortable vehicle taking feeling is ensured; the service life of the abrasion assembly is prolonged.

Description

technical field [0001] The invention belongs to the field of rail transportation, and in particular relates to a wear assembly for a rail vehicle through passage and a through passage with the same. Background technique [0002] The existing wear plates for rail vehicles are generally fixedly connected at the bottom with the coupler, and the top is limited in the vehicle length direction by two stoppers on the middle frame of the passageway. During the operation of this kind of rail vehicle, especially on the way of turning, the middle frame of the through channel will have lateral offset friction with the wear plate, and the rotation of the middle frame of the through channel is limited by two stoppers, which will cause very serious abnormalities. Noise and wear, affecting ride comfort and wear plate life. Contents of the invention [0003] In view of the above technical problems, the present invention provides a wear assembly, which does not produce abnormal noise durin...
