[0026] In some embodiments of this application, guide wheelset compositions suitable for different track gauges are provided, with reference to... Figure 1 and Figure 2 It includes a swing arm 100 and a guide wheel pair 200. The swing arm 100 is connected to the frame (not shown).

[0027] The guide wheelset 200 includes a bushing 210, a wheel axle 220, a drive mechanism 230, and a locking pin mechanism 240. The structure of the bushing 210 is shown in the figure. Figures 3 to 5 The structure of wheel axle 220 is referenced. Figure 6 Locking mechanism 240 (refer to) Figure 7 .

[0028] The guide wheel pair 200 includes a bushing 210, and the rotating arm 100 is connected to the bushing 210, for example, by welding or by an assembly structure. A first cavity 211 and a second cavity 212 are formed inside the bushing 210. The first cavity 211 and the second cavity 212 are arranged along the axial direction of the bushing 210, and the first cavity 211 is respectively provided at opposite ends of the second cavity 212.

[0029] The guide wheel pair 200 includes a wheel axle 220, and the wheel axle 220 is inserted into any first cavity 211. A guide wheel 250 is provided at one end of the wheel axle 220.

[0030] The guide wheelset 200 includes a drive mechanism 230, which is disposed in the second cavity 212 and connected to the other end of the wheel axle 220. The drive mechanism 230 is configured to drive the wheel axle 220 to move axially along the first cavity 211.

[0031] The guide wheelset 200 includes a locking pin mechanism 240, which is configured to lock the wheel axle 220 to restrict the axial movement of the wheel axle 220 along the first cavity 211.

[0032] Taking the conversion from 1435mm standard gauge to 1520mm wide gauge as an example, the track change process of the guide wheelset 200 in this application is as follows: The initial state is the 1435mm standard gauge track operation state, at which time the inner distance of the wheelset is 1353mm; during the track change, the drive mechanism 230 drives the wheel axle 220 to move away from the second cavity 212, thereby increasing the distance between the two guide wheels 250 and adjusting the inner distance of the wheelset to 1440mm. At this time, the vehicle can meet the requirements of the 1520mm wide gauge track operation, and the track gauge adjustment is completed.

[0033] This application provides a drive mechanism 230 in the second cavity 212 of the bushing 210 to drive the wheel axle 220 in the first cavity 211 to move axially. This allows for direct adjustment of the spacing between the guide wheels 250 on both sides. Without disassembling the wheelset body or replacing the vehicle, track gauge switching can be completed simply by the cooperation of the drive mechanism 230 and the locking pin mechanism 240. This simplifies the operation process, improves conversion efficiency, and effectively solves the technical problem that traditional methods cannot adapt to rapid conversion.

[0034] The guide wheelset 200 of this application can be flexibly adapted to various track gauge lines through the stroke adjustment of the drive mechanism 230 and the positioning and locking of the locking pin mechanism 240. It does not require the separate design and manufacture of special vehicles or wheelsets for different track gauges, thus improving the reusability of the equipment.

[0035] The locking mechanism 240 can reliably lock the axle 220 after it is adjusted to the target position, restricting its axial movement and ensuring that the distance between the guide wheels 250 is always kept at the design value corresponding to the target track gauge, thus avoiding track gauge deviation caused by the displacement of the axle 220 during vehicle operation.

[0036] In some embodiments of this application, the second cavity 212 includes a second cavity 212Ⅰ and a second cavity 212Ⅱ. The second cavity 212Ⅰ and the second cavity 212Ⅱ are arranged along the axial direction of the bushing 210. A drive mechanism 230 is respectively provided in the second cavity 212Ⅰ and the second cavity 212Ⅱ. The drive mechanism 230 is connected to the wheel axle 220 on the corresponding side.

[0037] The dual drive mechanism 230 is directly connected to the corresponding side wheel axle 220, which shortens the transmission path, eliminates the synchronization error caused by transmission backlash, and helps to improve the adjustment accuracy of the inner distance of the wheelset.

[0038] To meet the needs of changing track gauges, the dual drive mechanism 230 can be adapted in multiple modes without replacing the drive components. For example, when the inner distance of the left guide wheel 250 decreases by 2mm due to wear, the first drive mechanism 230 can be controlled independently to push the left wheel axle 220 to the left by 2mm without adjusting the right wheel axle 220, thus simplifying the maintenance process.

[0039] In some embodiments of this application, the drive mechanism 230 is a hydraulic cylinder or an electric push rod structure to realize automatic adjustment of the axial position of the wheel axle 220.

[0040] In some embodiments of this application, a partition 214 is provided inside the second cavity 212, which divides the second cavity 212 into two opposing cavities 212Ⅰ and 212Ⅱ. One side of the rotating arm 100 is connected to the outer wall of the second cavity 212Ⅰ, and the other side of the rotating arm 100 is connected to the outer wall of the second cavity 212Ⅱ. This helps to improve the structural stability of the bushing 210.

[0041] In some embodiments of this application, reference is made to Figure 4 A first guide portion 215 is provided on the inner peripheral wall of the first cavity 211, and the first guide portion 215 extends along the axial direction of the first cavity 211. (Refer to...) Figure 6 A second guide portion 222 is provided on the outer peripheral wall of the wheel axle 220, and the first guide portion 215 slides in conjunction with the second guide portion 222. For example, the first guide portion 215 is a long groove, and the second guide portion 222 is a long protrusion. The long protrusion is embedded in the long groove and guides the axial movement of the wheel axle 220.

[0042] In some embodiments of this application, reference is made to Figure 5 A first through hole 213 is provided on the bushing 210 that forms the first cavity 211. (Refer to...) Figure 6 A second through hole 221 is provided on the axle 220. (Refer to...) Figure 2 The pin 241 of the locking mechanism 240 passes through the first through hole 213 and the second through hole 221 so that the wheel axle 220 is locked in the target position after moving along the bushing 210.

[0043] In some embodiments of this application, the locking mechanism 240 further includes a hydraulic or pneumatic control unit (not shown) to lock the pin 241 in a target position. The hydraulic or pneumatic control unit enables the automatic operation of the locking mechanism 240, thereby automatically locking the axle 220 in the target position.

[0044] In some embodiments of this application, reference is made to Figure 1 and Figure 7 A mounting seat 260 is fitted onto the bushing 210 that forms the first cavity 211. The mounting seat 260 is connected to the frame via a hydraulic cylinder to achieve the lifting and lowering of the guide wheelset 200. The mounting seat 260 is provided with a third through hole 261, through which the pin 241 of the locking pin mechanism 240 passes.

[0045] In some embodiments of this application, reference is made to Figure 6 Multiple second perforations 221 are arranged at intervals along the axial direction of the wheel axle 220.

[0046] The adjustment process of the guide wheel pair 200 device in this application is as follows: the locking pin mechanism 240 releases the lock on the wheel axle 220; the drive mechanism 230 drives the wheel axle 220 to move, so that the two guide wheels 250 move closer or further apart according to the track gauge requirements; after the wheel axle 220 moves to the target position, the pin 241 of the locking pin mechanism 240 is inserted into the first through hole 213, the third through hole 261 and the corresponding second through hole 221, so as to lock the wheel axle 220 at the target position.

[0047] In the description of the above embodiments, specific features, structures, materials, or characteristics may be combined in any suitable manner in one or more embodiments or examples.

[0048] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention.
