Through the cooperation of vertical rudder wheel assembly, encoder, gear, curved plate, motor, wheel, electromagnetic brake, shell, straight pipe and oil injection structure, lubricating oil is poured into the pipe body, and then the lubricating oil is absorbed by the sponge. The electric push rod drives the pressing plate to move downward, the pressing plate extrudes the sponge, and then the lubricating oil absorbed in the sponge is discharged.

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] like Figures 1 to 7 As shown, the present invention provides a high-torque flexible sealed transmission dual-wheel vertical drive wheel, including a support assembly 1, and further comprising:

[0034] The drive assembly 2 is mounted on the top of the support assembly 1, and the output shaft end of the drive assembly 2 is fixedly connected to the transmission assembly 3;

[0035] Wheels 4 are arranged on both sides of the bottom of the support assembly 1, and the wheels 4 are connected to the transmission assembly 3;

[0036] The lubrication assembly 5 is fixedly connected to one side of the middle portion of the outer wall of the support assembly 1 and is located above the wheel 4;

[0037] The oil replenishing component 6 is movably connected to the interior of the lubricating component 5;

[0038] Among them, the lubrication component 5 includes a support frame 51, one end of the support frame 51 is movably connected to a rotating drum 52, the bottom of the rotating drum 52 is fixedly connected to a gear plate 53, a guide groove 54 is provided in an annular shape at the top end of the outer wall of the support frame 51, and the top of the support frame 51 is fixedly connected to an oil storage barrel 55 and an oil storage tank 56, and two nozzles 58 are provided on the side of the oil storage tank 56 close to the transmission component 3.

[0039] By means of the above scheme: by opening the guide groove 54, the connecting column 511 can slide along the track of the guide groove 54, thereby driving the limiting block 510 and the sealing plate 59 at the bottom end of the limiting block 510 to move downward, the sealing plate 59 moves downward to extrude the lubricating oil in the oil storage tank 56, thereby enabling the lubricating oil to be uniformly sprayed onto the transmission assembly 3 under the action of pressure through the two spray heads 58, and the operation is repeated, thereby realizing the lubrication effect of the transmission assembly 3, and further ensuring the normal operation and work of the double-wheel vertical driving wheel.

[0040] As shown in Figures 4 to 6 , the oil storage barrel 55 is fixedly connected at the bottom end of the side close to the oil storage tank 56, the oil storage barrel 55 is in communication with the oil storage tank 56 through the oil outlet pipe 57, the top end of the oil storage barrel 55 is provided with a circular top cover, the inside of the oil storage tank 56 is movably connected with the sealing plate 59, the top end of the sealing plate 59 is fixedly connected with the limiting block 510, one end of the limiting block 510 close to the rotating drum 52 is fixedly connected with the connecting column 511, and the connecting column 511 is movably clamped in the inside of the guide groove 54.

[0041] By means of the above scheme: by providing the circular top cover at the top end of the oil storage barrel 55, it is convenient for the operator to supplement the lubricating oil in the inside of the oil storage barrel 55, thereby ensuring the normal operation of the device.

[0042] As shown in Figure 6 and Figure 7 , the oil supplementing assembly 6 comprises a round plug 61, one end of the round plug 61 is fixedly connected with an inclined block 62, the outside of the inclined block 62 is sleeved with a spring 63, the two ends of the spring 63 are fixedly connected with the round plug 61 and the oil outlet pipe 57 respectively, the bottom of the inner cavity of the oil storage barrel 55 is fixedly connected with a limiting rod 64, the limiting rod 64 is composed of a round rod and a cross block, the cross block of the limiting rod 64 is movably clamped in the inside of the round plug 61, the inner wall of the round plug 61 is provided with a cross groove 65 matched with the limiting rod 64, one end of the inclined block 62 away from the round plug 61 is in a beveled shape, the beveled end of the inclined block 62 is located in the inside of the oil storage tank 56, one end of the round plug 61 away from the round plug 61 is in a beveled shape, and the beveled part of the round plug 61 is provided with a rubber gasket.

[0043] By means of the above scheme: when the sealing plate 59 moves upward to release the extrusion on the inclined block 62, at this time, the inclined block 62 will be reset under the action of the spring 63, thereby enabling the round plug 61 to release the sealing of the oil outlet pipe 57, subsequently, the lubricating oil in the inside of the oil storage barrel 55 will pass through the gap between the oil outlet pipe 57 and the round plug 61, thereby being smoothly conveyed from the oil storage barrel 55 to the inside of the oil storage tank 56, thereby realizing the continuous supplement of the lubricating oil in the inside of the oil storage tank 56, and achieving the effect of continuous spraying;

[0044] A rubber gasket is provided at the inclined surface of the round plug 61. Its function is that, since the rubber gasket has good corrosion resistance and oil resistance, it can resist the chemical substances in the lubricating oil. At the same time, the rubber gasket also has good sealing performance, which can improve the sealing effect of the round plug 61 on the oil outlet pipe 57.

[0045] like Figure 3 and Figure 4 As shown, the outer wall of the support frame 51 is provided with a slide groove 512 that cooperates with the connecting column 511. The slide groove 512 is used to circumferentially limit the connecting column 511 when the rotating drum 52 rotates. The inner wall of the support frame 51 away from the gear plate 53 is provided with a square groove. The end of the limit block 510 away from the connecting column 511 moves inside the square groove. The guide groove 54 is composed of two transverse grooves and two V-shaped grooves connected to each other. The gear plate 53 is meshed and connected with the transmission assembly 3. The transmission assembly 3 is located inside the support assembly 1. The gear plate 53 passes through the outer wall of the support assembly 1 and extends to the inside of the support assembly 1.

[0046] The above-mentioned solution is adopted: through the design of the square groove and the slide groove 512, its function is to limit the limit block 510 through the slide groove 512 and the square groove, so that after the connecting column 511 slides into the V-shaped groove of the guide groove 54, it can only drive the limit block 510 to move linearly in the vertical direction, thereby ensuring the stable operation of the device.

[0047] like Figure 4 and Figure 5 As shown, the sealing plate 59 is composed of an arc-shaped plate and two round rods. The outer wall of the arc-shaped plate fits with the inner wall of the oil storage tank 56. The round rods pass through the top of the oil storage tank 56 and extend to the outside of the oil storage tank 56. The end of the nozzle 58 away from the oil storage tank 56 passes through the outer wall of the support assembly 1 and extends to the inside of the support assembly 1. A gap is left between one end of the nozzle 58 and the transmission assembly 3.

[0048] The above solution is adopted: a gap is left between one end of the nozzle 58 and the transmission component 3. Its function is that since the lubricating oil is sprayed through the nozzle 58, a gap is left between the nozzle 58 and the transmission component 3, which can make the lubricating oil sprayed more evenly on the surface of the transmission component 3, thereby forming a thinner and more uniform oil film, thereby improving the lubrication effect.

[0049] The working principle and usage process of the present invention are as follows: the driving component 2 transmits power to the two wheels 4 through the transmission component 3, thereby driving the wheels 4 to rotate, thereby providing power for the device to move forward, backward or turn, and while the transmission component 3 rotates at a constant speed, since the transmission component 3 is meshed and connected with the gear plate 53, it will drive the rotating drum 52 to rotate together through the gear plate 53, thereby causing the connecting column 511 to slide along the trajectory of the guide groove 54. While the rotating drum 52 rotates, the connecting column 511 initially slides inside the horizontal groove of the guide groove 54. When the connecting column 511 slides to the inside of the V-shaped groove of the guide groove 54, the connecting column 511 will drive the limit block 510 to move downward under the action of the circumferential limit of the slide groove 512.

[0050] When the limit block 510 moves downward, it drives the sealing plate 59 to move synchronously, so that the sealing plate 59 abuts against the inclined surface of the inclined block 62. At this time, the circular plug 61 is limited in the horizontal direction by the limit rod 64, so that the sealing plate 59 squeezes the inclined block 62 and drives the circular plug 61 to move horizontally in the direction of the limit rod 64. After the circular plug 61 moves, it drives the rubber gasket at its inclined surface to abut against the inner wall of the oil outlet pipe 57, thereby sealing the oil outlet pipe 57, thereby completely blocking the oil path between the oil storage barrel 55 and the oil storage tank 56, and the lubricating oil inside the oil storage barrel 55 can no longer pass The oil outlet pipe 57 and the air pressure inside the oil storage tank 56 also change. Then, the limit block 510 continues to drive the sealing plate 59 downward, so that the sealing plate 59 squeezes the lubricating oil inside the oil storage tank 56. Under the action of pressure, the squeezed lubricating oil is forced to flow into the two nozzles 58 and is evenly sprayed toward the transmission component 3 through the nozzles 58. Then, the sprayed lubricating oil forms a uniform oil film on the tooth surface of the gear. This oil film can effectively reduce the friction coefficient of the transmission component 3 during operation, thereby reducing wear and heat generation.

[0051] When the connecting column 511 slides to the bottom end of the V-shaped groove, the rotating drum 52 continues to move, so that the connecting column 511 continues to move along the track of the V-shaped groove to drive the limit block 510 to move upward, and then drives the sealing plate 59 to move upward. After the sealing plate 59 moves upward, it will release the squeeze on the lubricating oil inside the oil storage tank 56, so that the lubricating oil stops spraying. When the sealing plate 59 moves up to the top of the inner wall of the oil storage tank 56, the sealing plate 59 will release the squeeze on the inclined block 62, so that the round plug 61 is Under the action of the elastic force of the spring 63, the inclined block 62 is driven to reset. After the round plug 61 and the inclined block 62 are reset, the rubber gasket on the inclined surface of the round plug 61 will release the seal on the oil outlet pipe 57, thereby opening the oil path between the oil storage barrel 55 and the oil storage tank 56. Subsequently, the lubricating oil inside the oil storage barrel 55 flows smoothly into the interior of the oil storage tank 56 through the gap between the oil outlet pipe 57 and the round plug 61, thereby achieving the effect of replenishing the lubricating oil inside the oil storage tank 56, thereby facilitating the recycling of the device.

[0052] The device is in continuous operation, the transmission assembly 3 will drive gear plate 53 continuous rotation, until the connecting column 511 slip to another V-shaped groove inside, then, the above operation repeatedly, so that the different parts of the transmission assembly 3 continuous spray lubricating oil, and thus achieve the effect of lubrication of the transmission assembly 3, thereby preventing the transmission assembly 3 continuous operation after the phenomenon of excessive wear, and thus ensure the normal operation and work of the double wheel vertical drive wheel.
