[0037] like Figure 1-Figure 4 As shown, the present invention is a monorail suspended rail vehicle, comprising an I-shaped rail 1, a suspension device 2 and a carriage 3. The carriage 3 is suspended at the lower part of the rail 1 through the suspension device 2 and travels on the rail 1.

[0038] The track 1 includes a vertical plate 102 . A top plate 101 is disposed on the upper portion of the vertical plate 102 , and a bottom plate 103 is disposed on the lower portion of the vertical plate 102 .

[0039] The specific structure of the suspension device 2 is as follows: Figure 5 , Figure 6 As shown, the suspension device 2 includes a first suspension component and a second suspension component respectively located on both sides of the vertical plate 102 and symmetrically arranged. The suspension device 2 is a combined structure and is symmetrically arranged on both sides of the vertical plate 102 to keep both sides of the track 1 balanced.

[0040] The first suspension component includes a first suspension bracket 201 and a first disc suspension bracket 202. The first disc suspension bracket 202 is located at the lower part of the first suspension bracket 201. The first suspension bracket 201 is provided with a first walking and guiding component that walks on the track 1. The second suspension component includes a second suspension bracket 203 and a second disc suspension bracket 204. The second disc suspension bracket 204 is located at the lower part of the second suspension bracket 203. The second suspension bracket 203 is provided with a second walking and guiding component that walks on the track 1.

[0041] Among them, the first walking and guiding assembly and the second walking and guiding assembly both include guide wheels 205 and walking wheels 206. The walking wheels 206 are respectively installed on the inner arms of the first suspension bracket 201 and the second suspension bracket 203 and walk on the base plate 103. The guide wheels 205 are respectively installed on the upper and lower ends of the first suspension bracket 201 and the second suspension bracket 203 and walk on the vertical plate 102.

[0042] The guide wheels 205 and the running wheels 206 work together to drive the suspension device 2 to move along the track 1. The guide wheels 205 are located on both sides of the vertical plate 102 and move along the vertical plate 102. A gap is provided between the wheel rims of the guide wheels 205 and the vertical plate 102. When the rail vehicle is running normally, there is no contact between the guide wheels 205 and the vertical plate 102, and no friction resistance is generated, which has a protective effect on the guide wheels 205 and the track 1; when the rail vehicle turns, the guide wheels 205 move along the initial running direction under the action of inertia, the track 1 turns, and the guide wheels 205 abut against the vertical plate 102 of the track 1. Contact friction is generated between 205 and the track 1, and the guide wheel 205 is set as a horizontal guide wheel. The horizontal guide wheel rotates horizontally along the axis of the vertical direction. In the embodiment of the present invention, one traveling wheel 206 in each traveling and guiding assembly corresponds to four guide wheels 205. When the suspension device 2 drives the carriage 3 to run, the guide wheel 205 can prevent the traveling wheel 206 from sliding out of the track 1 and tipping over to ensure the overall balance, and can also guide the traveling wheel 206 to run along the extension direction of the track 1, so that the traveling wheel 206 can run stably when turning, and has a transition effect of assisting the traveling wheel 206 to turn.

[0043] An annular slide with a slide cutout is formed in the first disc suspension bracket 202 and the second disc suspension bracket 204 respectively, and a rotating component 4 is provided in the annular slide. The rotating component 4 enters through the slide cutout and is connected with the annular slide. The rotating component 4 includes a connecting arm 401 and a rotating wheel 402 installed at its end. The rotating wheel 402 is set as a vertical rotating wheel. The lower end surface of the vertical rotating wheel rim rotates horizontally along the lower surface of the annular slide. A sliding groove is provided on the side wall of the annular slide. A slider 403 that moves with the sliding groove is provided on the side surface of the vertical rotating wheel rim. The rotating component 4 realizes horizontal rotation on the annular slide by the rotating wheel 402 walking on the lower surface of the annular slide and the slider 403 walking along the side of the annular slide. A connecting component 5 is installed at the lower part of the rotating component 4. The car 3 is installed at the lower part of the suspension device 2 through the connecting component 5, thereby driving the car 3 to rotate horizontally at any angle relative to the suspension frame, thereby achieving a technical effect of a small horizontal turning radius, making the overall mechanism more flexible and suitable for sharp turns or steep curves.

[0044] The carriage 3 includes a power unit 302 and a passenger unit 301. Figure 7(a) , 7(b) As shown in 7(c), a driving device 6 is provided on the power unit 302, and the driving device 6 includes a driving gear 601, a driver 604, a driving bracket 602 and a driving shaft 603. The driver 604 is installed on the driving gear 601 through the driving shaft 603, and both ends of the driving shaft 603 are respectively connected to the driving bracket 602, and the upper end of the driving bracket 602 is connected to the connecting component 5.

[0045] Specifically, the connecting component 5 is a supporting disc, wherein the carriage 3 of the passenger part 301 is fixedly connected to the rotating component 4 via the supporting disc, and the carriage 3 of the power part 302 is connected to the supporting disc via the driving bracket 602 and then fixedly connected to the rotating component 4.

[0046] Among them, in an embodiment of the present invention, the driver 604 can adopt a variety of drive structures to meet different driving environments, such as a reducer drive structure (as shown in Figure 7(a)), a hub motor drive structure (as shown in Figure 7(b)) and a hydraulic motor drive structure (as shown in Figure 7(c)).

[0047] As shown in Figures 8(a), 8(b), 8(c) and 8(d), a rack 104 is provided at the lower portion of the track 1, and the rack 104 is mounted at the lower portion of the base plate 103. The drive gear 601 is meshed with the rack 104. In the embodiment of the present invention, the drive gear 601 and the rack 104 can adopt a variety of structures to meet different driving environments, such as a structure in which a pin gear meshes with an integrated rack (as shown in Figure 8(a)), a structure in which a spur gear meshes with an integrated rack (as shown in Figure 8(b)), a structure in which a spur gear meshes with a trapezoidal inlaid tooth rack (as shown in Figure 8(c)) and a structure in which a spur gear meshes with a cylindrical inlaid tooth rack (as shown in Figure 8(d)).

[0048] The present invention transmits traction force through the meshing and cooperation of the driving gear 601 and the rack 104. When the rail vehicle is climbing a slope, the cooperation between the driving gear 601 and the rack 104 causes the rail vehicle to move upward. Compared with the ordinary track 1, the present invention has a strong climbing ability, high efficiency, safety and reliability, and is suitable for the operation of rail vehicles on large slopes and the traction of heavy loads. The maximum climbing angle can reach 30°.

[0049] The embodiments described above are merely descriptions of preferred implementations of the present invention and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
