The output end of the reducer 14 includes an output shaft that passes through the housing of the reducer 14. Both ends are connected to the fixing sleeve 22 via a flat key. The inner side of the fixing sleeve 22 on the output shaft is connected to the small output sprocket 21 and the large output sprocket 20 via bearings. The small output sprocket 21 and the large output sprocket 20 are located on both sides of the reducer 14 housing. The top left and right sides of the housing are hinged with shift fork support seats 18, and the two shift fork support seats 18 are located above the small output sprocket 21 and the large output sprocket 20. The ends of the two shift fork support seats 18 furthest from the reducer 14 are slidably connected to the middle of the clutch shift fork 16. The shift fork 16 can rotate around the hinge. One end of each of the two clutch shift forks 16 is connected to the sliding rod of their respective telescopic cylinder 19 via a rotating shaft.

The other end of brake 29 is fixed to drive frame 7. The bottom middle sides of drive frame 7 are bolted to rail clamping devices 10. The small output sprocket 21 drives the large drive gear 27 to rotate. The large drive gear 27 and drive gear 26 share the same bearing, driving drive gear 26 to rotate. Steel wheel 25 rotates freely without power, completing the gear operation mode. The large output sprocket 20 drives the small gear 28 to rotate. The small gear 28 drives drive wheel shaft 24 to rotate, driving steel wheel 25 to rotate. Drive gear 26 idles without power, completing the steel wheel operation mode.

[0036] like Figure 4 and 9 As shown, the passive load-bearing wheel system 9 includes a wheel axle 31, with two load seats 30 slidably connected to both ends of the wheel axle 31. The wheel axle 31 can rotate around the load seats 30. The load seats 30 are fixed to the drive frame 7. Steel wheels 25 are fixed to the inner sides of the two load seats 30 on the wheel axle 31. Shock absorbers 8 are connected to the top of the load seats 30. A brake 32 and an electronic speed measuring device 33 are connected to the wheel axle 31 through a mounting seat 44. The other end of the brake 32 is connected to the drive frame 7 through a spherical hinge. The speed measuring wheel of the electronic speed measuring device 33 is connected to the wheel axle 31 through a tension spring.

[0037] like Figure 10As shown, the rail clamping device 10 includes a mounting frame 34, rail clamping wheels 36, and a second telescopic cylinder 38. The mounting frame 34 slides vertically through guide shafts 35 on both sides. The top ends of the two guide shafts 35 are connected by a connecting plate 37, and the bottoms of the two guide shafts 35 are slidably connected to the rail clamping wheels 36 through bearings. The rail clamping wheels 36 can rotate around the guide shafts 35. The second telescopic cylinder 38 is fixed in the middle of the mounting frame 34. The cylinder rod of the second telescopic cylinder 38 is fixed to the connecting plate 37 with its upward direction. The mounting frame 34 is connected to the drive frame 7 by bolts. The second telescopic cylinder 38 controls the up and down movement of the guide shafts 35 to realize the extension and retraction of the rail clamping wheels 36. In gear operation mode, the rail clamping wheels 36 are engaged with the irregular rails on both sides of the gear rail clamping track 46 to prevent derailment.

[0038] like Figure 11 As shown, the control room 6 includes a control center 39 and a hydraulic control section. The hydraulic control section includes a hydraulic oil tank 40, an oil pump motor 41, an oil pump 42, and an integrated control valve block 43. The oil pump motor 41 is connected to the oil pump 42, and the oil pump 42 is connected to the hydraulic oil tank 40. The integrated control valve block 43 is connected to the oil pump 42 through a pipeline. The control center 39 is equipped with steel wheel travel commands and gear travel commands, and different modes are realized through the hydraulic control section combined with software programs.

[0039] Work process:

[0040] When climbing is required, the operator sends a gear-driven driving command from the driver's cab 1 to the control center 39. The control center 39 then sends a command to the hydraulic system, which provides power to the hydraulic control system via the oil pump motor 41. The control center 39 controls the retraction of the cylinder rod of the telescopic cylinder 38, and the guide shaft 35 drives the rail-clamping wheel 36 to descend below the irregular rails supporting both sides of the gear rail clamping track 46, engaging with the irregular rails on both sides. At this time, the rail-clamping wheel 36 has the function of clamping the rail. The control center 39 controls the drive mode switch, controlling the extension of the telescopic cylinder 19 on the side of the output small sprocket 21 and the retraction of the telescopic cylinder 19 on the side of the output large sprocket 20, and the retraction of the output small sprocket 21. The clutch fork 16 on the side engages the internal splines of the clutch sliding sleeve 17 with the external splines of the output small sprocket 21 and the fixed sleeve 22. The clutch fork 16 on the side of the output large sprocket 20 disengages the internal splines of the clutch sliding sleeve 17 with the external splines of the output large sprocket 20 and the fixed sleeve 22. The output small sprocket 21 outputs power through the double-row roller chain 13 to drive the drive large gear 27 to rotate. The drive large gear 27 and the drive gear 26 share the same bearing, driving the drive gear 26 to rotate. The drive gear 26 engages with the toothed rail of the toothed rail track 46 on the ramp. The steel wheel 25 rotates freely without power output, and the locomotive is in a gear-driven state. Figure 12 As shown.

[0041] In a smooth environment, the operator in the driver's cab 1 sends a steel wheel travel command to the control center 39. The control center 39 then sends a command to the hydraulic system, which provides power to the hydraulic control system via the oil pump motor 41. The control center 39 controls the extension of the cylinder rod of the second telescopic cylinder 38, and the guide shaft 35 drives the rail clamping wheel 36 to rise above the irregular rails supporting both sides of the toothed rail clamping track 46. At this time, the rail clamping wheel 36 does not have a rail clamping function. The control center 39 controls the drive mode switch, controls the retraction of the first telescopic cylinder 19 on the side of the small output sprocket 21, and controls the extension of the first telescopic cylinder 19 on the side of the large output sprocket 20. The clutch fork 16 on the side of the large sprocket 20 engages the internal spline of the clutch sliding sleeve 17 with the external spline of the output large sprocket 20 and the fixed sleeve 22. The clutch fork 16 on the side of the output small sprocket 21 disengages the internal spline of the clutch sliding sleeve 17 with the external spline of the output small sprocket 21 and the fixed sleeve 22. At this time, the output power from the output large sprocket 20 is transmitted to the pinion 28 via the double-row roller chain 12. The pinion 28 drives the drive wheel shaft 24 to rotate. The steel wheel 25 adheres to the ordinary track 45, and the drive gear 26 rotates freely without power output. The locomotive is in a state of steel wheel motion. Figure 13 As shown.
