Embodiment

(12) An anti-derailment bogie of a rail vehicle of the disclosure as shown in FIG. 4, comprises a bogie 9 and an anti-derailment apparatus 4. The upper portion of the anti-derailment apparatus 4 is mounted at the bottom of the bogie 9, and the lower portion of the anti-derailment apparatus 4 hangs between the two front and rear wheelsets 6 to which the bogie 9 corresponds.

(13) FIGS. 1-4 also illustrates the anti-derailment apparatus 4 for the bogie of a rail vehicle of the disclosure, and the anti-derailment apparatus 4 comprises a pair of mounting seats 1 which are mounted at the bottom of the bogie 9 of the rail vehicle. The pair of mounting seats 1 comprise a first mounting seat 11 which is located at the left side of the bottom of the bogie 9 and a second mounting seat 12 which is located at the right side of the bottom of the bogie 9. Preferably, the first mounting seat 11 and the second mounting seat 12 can be arranged symmetrically along the centre line of the ground rail 8 (but it is not necessary), and each of the first mounting seat 11 and the second mounting seat 12 is configured with an anti-derailment slide plate 2 extending toward the ground rail 8.

(14) As shown in FIG. 2, the mounting seat 1 in the embodiment is an L shape, and the L shaped mounting seat 1 comprises a horizontal top surface 13 which can be fastened to the bogie 9 through the fastener 3 (in the embodiment, it is a bolt), and also comprises a vertical side surface 14 which can be fastened to the anti-derailment slide plate 2 through the fastener 3 (in the embodiment, it is a bolt). As such, both the anti-derailment slide plate 2 and the mounting seat 1 are detachable.

(15) As shown in FIGS. 2-3, the anti-derailment slide plate 2 of the embodiment is configured as a slide plate of which the vertical length or height is adjustable. In particular, the mounting seat 1 is provided with a strip-shaped sliding groove 15 which extends along the vertical direction, and the anti-derailment slide plate 2 is fitted on the mounting seat 1 through the fastener 3 which can slide upward and downward in the sliding groove 15. As shown in FIGS. 2-3, the contact surfaces of the anti-derailment slide plate 2 and the mounting seat 1 are configured as zigzag butting surfaces which mesh with each other (or in other ways of a relative large friction coefficient). Such a structure can achieve the upward and downward adjustment of the position of the anti-derailment slide plate 2, and can also adjust the height of the lower surface 21 of the anti-derailment slide plate 2 (further adjust the anti-derailment apparatus 4) through the zigzag meshing, avoiding the interference of the anti-derailment slide plate 2 with the infrastructure such as the ground rail 8 etc. caused due to the reduction of the radius of the wheel resulting from the re-profiling repair of the wheelset 6.

(16) As shown in FIGS. 1 and 3, both ends of the lower portion of the anti-derailment slide plate 2 of the embodiment are provided with a keep-space area 5. The keep-space area 5 is disposed particularly at the side of the anti-derailment slide plate 2 facing the ground rail, and the anti-derailment slide plate 2 provided with the keep-space area 5 is a tip shape or a wedge shape (equivalent to two chamfers with relatively great radius being disposed at both sides of the lower portion of the anti-derailment slide plate 2). As such, it can ensure that the whole anti-derailment apparatus 4 has good switch-passing performance and does not interfere with the ground rail 8.

(17) In the embodiment, the transverse position of the anti-derailment slide plate 2 on the bogie 9 and the extending length thereof in the vertical direction are set to meet the following requirements simultaneously:

(18) 1) making the anti-derailment slide plate 2 located at the inside of the ground rail 8 when the rail vehicle runs normally (referring to FIG. 4);

(19) 2) when at least one wheelset 6 of the rail vehicle climbs rail, the anti-derailment slide plate 2 acts on the ground rail 8 to form lateral limitation points so as to limit the freedom of the rail vehicle and make it still constrained by the ground rail 8 (referring to FIG. 5).

(20) As shown in FIG. 4, the transverse position of the anti-derailment slide plate 2 of the embodiment is achieved by controlling the lateral distance of the anti-derailment slide plate 2 and the flange 7 of the wheelset 6. In particular, in the embodiment, the transverse position of the anti-derailment slide plate 2 on the bogie 9 ensures that the anti-derailment slide plate 2 and the flange 7 are located at the same line (that is, the acting surface of the anti-derailment slide plate and the flange 7 are located in the same vertical plane). The extending length of the anti-derailment slide plate 2 of the embodiment in the vertical direction is achieved by controlling the height of the lower surface 21 (with respect to ground) of the anti-derailment apparatus (i.e., the anti-derailment slide plate 2), and the vertical length of the anti-derailment slide plate 2 of the embodiment ensures that the height of the lower surface 21 of the anti-derailment apparatus (i.e., the anti-derailment slide plate 2) is aligned with the height of the flange 7. As such, the contact of the middle anti-derailment slide plate 2 with the inside of the ground rail 8 is not ineffective while one wheelset 6 climbs rail, and the anti-derailment slide plate 2 can pass railway switches well and does not interfere with the ground rail 8.

(21) Of course, the anti-derailment slide plate 2 in the disclosure should also have enough lateral strength, to ensure that the anti-derailment slide plate 2 does not generate a great deformation while suffering the lateral force. Further, the wheelset 6 climbing rail does not derail due to the excessive lateral deformation of the anti-derailment slide plate 2. And preferably, the anti-derailment apparatus 4 of the disclosure uses light-weight and wear-resistance materials, to ensure that the dynamics performance of the vehicle system does not deteriorate.

(22) The anti-derailment apparatus 4 of the embodiment mainly applies to the situation where axle-box springs does not exist or axle-box springs have relatively great rigidity, and the operating principle upon applying is shown in FIG. 5. When the wheelset 6 at one side of the bogie 9 of a rail vehicle climbs rail, the anti-derailment slide plate 2 can still contact with the inside of the ground rail 8, and since a triangular system constituted by the rigidity of the bogie 9 and the contact of the anti-derailment slide plate 2 with the ground rail 8 forms a stable mechanism, a further lateral displacement of the wheelset 6 climbing rail is limited. Furthermore, the wheelset 6 climbing rail has an automatic centering function, and will resume to the normal position from the state of climbing rail, avoiding the occurrence of derailment.
