Since a drive wheel 4 is arranged outside the motor 3, and both sides below the drive wheel 4 are respectively connected to the first load-bearing wheel 5 and the second load-bearing wheel 6, and at the same time, the outside of the drive wheel 4, the first load-bearing wheel 5, and the second load-bearing wheel 6 are connected by a crawler ring 9, when the motor 3 drives the drive wheel 4 to run, at this time, the drive wheel 4 will synchronously drive the first load-bearing wheel 5 and the second load-bearing wheel 6 to rotate on the second support component 7 and the third support component 8 respectively, and at this time, the second support component 7 and the third support component 8 are in the same direction, so as to drive the crawler ring 9 to travel on the ground. And under its own characteristics, the crawler ring 9 can move on special terrains or working scenarios such as snow, desert, and swamp. At the same time, the crawler ring 9 cooperating with the two positioning components 1 can also play a role in protecting the motor 3, so as to improve the use safety and service life of the motor 3.
[0041] Refer to Figure 5 、 Figure 6 , The positioning component 1 includes a vertical plate 11. A flat hole 12 for installing the first support component 2 is opened at a position above the middle of the side wall surface of the vertical plate 11. A sliding hole 13 and a mounting hole 14 for installing the second support component 7 are opened at a position near one end at the bottom of the side wall surface of the vertical plate 11, where the sliding hole 13 is located outside the mounting hole 14. A shaft hole 15 for installing the third support component 8 is opened at a position near the other end at the bottom of the side wall surface of the vertical plate 11;
[0042] By positioning the vertical plate 11 in the positioning component 1, it can not only support the skeleton but also provide space for opening the flat hole 12, the sliding hole 13, the mounting hole 14, and the shaft hole 15. Through the flat hole 12, the first support component 2 can be inserted and installed, and the first support component 2 can be prevented from rotating in its inner cavity, thereby improving the stability of the use of the first support component 2. Through the mounting hole 14, one side of the second support component 7 can be installed and fixed, and through the sliding hole 13, the second support component 7 can be inserted and limited, and the position of the second support component 7 can be flexibly adjusted, thereby being able to adjust the position of the first load-bearing wheel 5. Through the shaft hole 15, the third support component 8 can be installed and fixed.
[0043] Refer to Figure 5 - Figure 7 , the first support component 2 includes a first shaft rod 21 passing through the axis of the motor 3. Both ends of the first shaft rod 21 are respectively fixedly connected with a first flat screw 22 and a second flat screw 23 for observing the positioning component 1.

[0044] Through the first shaft rod 21 in the first support assembly 2, it can be installed between the two vertical plates 11, and the motor 3 can be installed through the two bearings 24. At the same time, it can be inserted into the flat holes 12 on the two vertical plates 11 through the first flat screw rod 22 and the second flat screw rod 23 respectively. At this time, the two flat holes 12 can not only serve the purpose of installing the first flat screw rod 22 and the second flat screw rod 23, but also limit the first flat screw rod 22 and the second flat screw rod 23, thereby preventing the first shaft rod 21 from rotating. Since a wire hole 25 is provided on one side of the bottom of the first shaft rod 21 and close to the first flat screw rod 22, through the wire hole 25, it is convenient for the external wire cable to be connected to the motor 3, and thus the motor 3 can be powered. Since a first nut 26 is rotatably connected to the first flat screw rod 22, and an internal thread groove 29 for rotatably connecting the second flat screw rod 23 is provided at one end of the support shaft 28, and the first nut 26 and the support shaft 28 are respectively located outside the two positioning assemblies 1, the first flat screw rod 22 and the second flat screw rod 23 can be locked and limited respectively through the first nut 26 and the support shaft 28, thereby improving the stability of their installation on the vertical plate 11. Since a first limiting tube 27 is sleeved on the second flat screw rod 23, and the first limiting tube 27 is located between the two positioning assemblies 1, through the first limiting tube 27, the purpose of adjusting the distance between the two vertical plates 11 can be achieved. Since the other end of the support shaft 28 is rotatably connected to a second nut 210, it is convenient for the support shaft 28 to cooperate with the second nut 210 to install it at the designated position on the tracked electric vehicle frame.
[0045] Refer to Figure 5 、 Figure 6 、 Figure 8 - Figure 10 The second support assembly 7 includes a second shaft rod 71 for passing through the first load-bearing wheel 5 and two fixing frames 78 provided on the outer walls of the two positioning assemblies 1. A second limiting tube 72 and a third limiting tube 73 are respectively sleeved on both sides of the first load-bearing wheel 5 on the second shaft rod 71; fourth limiting tubes 74 are sleeved on the second shaft rod 71 near both ends, connection heads 75 are sleeved on the second shaft rod 71 outside the two fourth limiting tubes 74, and both ends of the second shaft rod 71 are rotatably connected to third nuts 76, and external threaded rods 77 are fixedly provided at one ends of the two connection heads 75; through holes 79 for inserting the external threaded rods 77 are provided on the side walls of the two fixing frames 78, and fourth nuts 710 and fifth nuts 711 are respectively rotatably connected to the front and rear sides of the fixing frames 78 on the external threaded rods 77, wherein the fifth nut 711 is close to the connection head 75 side. The second limiting tube 72 and the third limiting tube 73 are both located between the two positioning assemblies 1, the two fourth limiting tubes 74 are respectively located outside the two positioning assemblies 1, and the lengths of the second limiting tube 72 and the third limiting tube 73 are different;
[0046] When it is necessary to install a limit on the first load-bearing wheel 5, first insert the first load-bearing wheel 5 onto the second shaft 71 in the second support assembly 7, then sleeve the second limit tube 72 and the third limit tube 73 onto the second shaft 71, and make the second limit tube 72 and the third limit tube 73 located on both sides of the first load-bearing wheel 5 respectively. Then insert both ends of the second shaft 71 into two slide holes 13 on two vertical plates 11. Next, install a fourth limit tube 74, a connector 75, and a third nut 76 on both ends of the second shaft 71 in sequence from inside to outside. By tightening the third nut 76, the second shaft 71 can be initially installed and fixed. Through the fixing bracket 78, it can be both fixedly installed on the outer wall of the vertical plate 11 and engaged in the inner cavity of the mounting hole 14, thereby improving the stability of the fixing bracket 78 in use. At the same time, the outer threaded rod 77 at one end of the connector 75 can be inserted and installed through the through hole 79. Since fourth nuts 710 and fifth nuts 711 are respectively rotatably connected to the outer threaded rod 77 at the front and rear positions of the fixing bracket 78, and the fifth nut 711 is close to the connector 75 side, by rotating and adjusting the fourth nut 710 and the fifth nut 711, the outer threaded rod 77 can be fixed on the fixing bracket 78, and the position of the outer threaded rod 77 of the fixing bracket 78 can be adjusted. Furthermore, the second shaft 71 can be limited again to improve the stability of the second shaft 71 in use. Since the second limit tube 72 and the third limit tube 73 are both located between the two positioning components 1, and the lengths of the second limit tube 72 and the third limit tube 73 are different, and the two fourth limit tubes 74 are respectively located outside the two positioning components 1. At this time, the second limit tube 72 and the third limit tube 73 with different lengths can be used to limit the first load-bearing wheel 5, thereby preventing the first load-bearing wheel 5 from moving left and right on the second shaft 71. Through the two fourth limit tubes 74, the purpose of supporting the connector 75 can be achieved, and further the connector 75 and the outer threaded rod 77 can be on the same axis, thereby improving the structural strength of the two.
[0047] Refer to Figure 5 , Figure 6 and Figure 11 , the third support assembly 8 includes a third shaft 81 for passing through the second load-bearing wheel 6. A fifth limit tube 82 and a sixth limit tube 83 are respectively sleeved on both sides of the second load-bearing wheel 6 on the third shaft 81. Both ends of the third shaft 81 are rotatably connected with sixth nuts 84. The lengths of the fifth limit tube 82 and the sixth limit tube 83 are different. Among them, the fifth limit tube 82 and the sixth limit tube 83 are both located between the two positioning components 1, and the two sixth nuts 84 are respectively located outside the two positioning components 1;
[0048] When it is necessary to limit the second load-bearing wheel 6, first insert the second load-bearing wheel 6 onto the third shaft rod 81 in the third support assembly 8, and then sleeved the fifth limiting tube 82 and the sixth limiting tube 83 onto the third shaft rod 81, and make the fifth limiting tube 82 and the sixth limiting tube 83 located on both sides of the second load-bearing wheel 6 respectively. Then insert both ends of the third shaft rod 81 into two shaft holes 15 on two vertical plates 11 respectively. Then rotate and install two sixth nuts 84 at both ends of the second shaft rod 71 and outside the two vertical plates 11, and by tightening the sixth nuts 84, the third shaft rod 81 can be installed and fixed, thereby improving the stability of the third shaft rod 81 during use. Since the lengths of the fifth limiting tube 82 and the sixth limiting tube 83 are different, and both the fifth limiting tube 82 and the sixth limiting tube 83 are located between the two positioning components 1, at this time, the fifth limiting tube 82 and the sixth limiting tube 83 with different lengths can be used to limit the second load-bearing wheel 6, so as to prevent the second load-bearing wheel 6 from moving left and right on the third shaft rod 81.
[0049] During use: Through the first support assembly 2, the motor 3 can be installed, enabling the motor 3 to run stably on it, and it can also be firmly installed on the two positioning components 1 distributed symmetrically. At the same time, it can also be connected to the frame of the tracked electric vehicle. Then through the second support assembly 7 and the third support assembly 8, the first load-bearing wheel 5 and the second load-bearing wheel 6 can be installed respectively, and can also be installed at the specified positions of the two positioning components 1 respectively, so that the first load-bearing wheel 5 and the second load-bearing wheel 6 can run smoothly on the two positioning components 1. Since a driving wheel 4 is arranged outside the motor 3, and both sides below the driving wheel 4 are connected to the first load-bearing wheel 5 and the second load-bearing wheel 6 respectively, and at the same time, the driving wheel 4, the first load-bearing wheel 5 and the second load-bearing wheel 6 are connected by a tracked ring 9 on the outside. Therefore, when the motor 3 drives the driving wheel 4 to run, at this time, the driving wheel 4 will synchronously drive the first load-bearing wheel 5 and the second load-bearing wheel 6 to rotate on the second support assembly 7 and the third support assembly 8 respectively, and at this time, the second support assembly 7 and the third support assembly 8 are in the same direction, and then the tracked ring 9 can be driven to travel on the ground. And due to the characteristics of the tracked ring 9 itself, it can move on special terrains or working scenarios such as snow, desert, swamp, etc. At the same time, the tracked ring 9 cooperating with the two positioning components 1 can also play a role in protecting the motor 3, so as to improve the safety and service life of the motor 3.
[0050] By positioning the vertical plate 11 in the positioning component 1, it can not only support the skeleton but also provide space for opening the flat hole 12, the sliding hole 13, the mounting hole 14, and the shaft hole 15. Through the flat hole 12, the first support component 2 can be inserted and installed, and the first support component 2 can be prevented from rotating in its inner cavity, thereby improving the stability of the use of the first support component 2. Through the mounting hole 14, one side of the second support component 7 can be installed and fixed, and through the sliding hole 13, the second support component 7 can be inserted and limited, and the position of the second support component 7 can be flexibly adjusted, thereby adjusting the position of the first load-bearing wheel 5. Through the shaft hole 15, the third support component 8 can be installed and fixed.
[0051] Through the first shaft rod 21 in the first support component 2, it can be installed between the two vertical plates 11, and the motor 3 can be installed through the two bearings 24. At the same time, it can also be inserted into the flat holes 12 on the two vertical plates 11 through the first flat screw rod 22 and the second flat screw rod 23 respectively. At this time, the two flat holes 12 can not only serve the purpose of installing the first flat screw rod 22 and the second flat screw rod 23 but also limit the first flat screw rod 22 and the second flat screw rod 23, thereby preventing the first shaft rod 21 from rotating. Since a wire hole 25 is opened at the bottom side of the first shaft rod 21 and near the first flat screw rod 22, through the wire hole 25, the external cable can be conveniently connected to the motor 3, thereby supplying power to the motor 3. Since a first nut 26 is rotatably connected to the first flat screw rod 22, and an internal thread groove 29 for rotatably connecting the second flat screw rod 23 is opened at one end of the support shaft 28, and the first nut 26 and the support shaft 28 are respectively located outside the two positioning components 1, the first flat screw rod 22 and the second flat screw rod 23 can be locked and limited through the first nut 26 and the support shaft 28 respectively, thereby improving the stability of their installation on the vertical plate 11. Since a first limiting tube 27 is sleeved on the second flat screw rod 23, and the first limiting tube 27 is located between the two positioning components 1, through the first limiting tube 27, the purpose of adjusting the distance between the two vertical plates 11 can be achieved. Since a second nut 210 is rotatably connected to the other end of the support shaft 28, the support shaft 28 can be conveniently installed at the specified position of the tracked electric vehicle frame in cooperation with the second nut 210.
[0052] When it is necessary to install a limit on the first load-bearing wheel 5, first insert the first load-bearing wheel 5 onto the second shaft 71 in the second support assembly 7, then sleeve the second limit tube 72 and the third limit tube 73 onto the second shaft 71, and make the second limit tube 72 and the third limit tube 73 located on both sides of the first load-bearing wheel 5 respectively. Then insert both ends of the second shaft 71 into two slide holes 13 on two vertical plates 11. Next, install a fourth limit tube 74, a connector 75, and a third nut 76 on both ends of the second shaft 71 from the inside to the outside in sequence. By tightening the third nut 76, the second shaft 71 can be initially installed and fixed. Through the fixing bracket 78, it can not only be fixedly installed on the outer wall of the vertical plate 11 but also be engaged in the inner cavity of the installation hole 14, thereby improving the stability of the use of the fixing bracket 78. At the same time, the outer threaded rod 77 at one end of the connector 75 can be inserted and installed through the through hole 79. Since the fourth nut 710 and the fifth nut 711 are respectively rotatably connected to the outer threaded rod 77 at the front and rear positions of the fixing bracket 78, and the fifth nut 711 is close to the connector 75, by rotating and adjusting the fourth nut 710 and the fifth nut 711, the outer threaded rod 77 can be fixed on the fixing bracket 78, and the position of the outer threaded rod 77 of the fixing bracket 78 can be adjusted, thereby being able to limit the second shaft 71 again to improve the stability of the use of the second shaft 71. Since the second limit tube 72 and the third limit tube 73 are both located between the two positioning components 1, and the lengths of the second limit tube 72 and the third limit tube 73 are different, while the two fourth limit tubes 74 are respectively located outside the two positioning components 1. At this time, the second limit tube 72 and the third limit tube 73 with different lengths can be used to limit the first load-bearing wheel 5, thereby preventing the first load-bearing wheel 5 from moving left and right on the second shaft 71. Through the two fourth limit tubes 74, the purpose of supporting the connector 75 can be achieved, thereby enabling the connector 75 and the outer threaded rod 77 to be on the same axis, and further improving the structural strength of the two.
[0053] When it is necessary to install a limit on the second load-bearing wheel 6, first insert the second load-bearing wheel 6 onto the third shaft 81 in the third support assembly 8, and then sleeve the fifth limit tube 82 and the sixth limit tube 83 onto the third shaft 81, with the fifth limit tube 82 and the sixth limit tube 83 located on both sides of the second load-bearing wheel 6 respectively. Then insert the two ends of the third shaft 81 into two shaft holes 15 on two vertical plates 11 respectively. Next, rotate and install two sixth nuts 84 at both ends of the second shaft 71 and outside the two vertical plates 11. By tightening the sixth nuts 84, the third shaft 81 can be installed and fixed, thereby improving the stability of the third shaft 81 during use. Since the lengths of the fifth limit tube 82 and the sixth limit tube 83 are different, and both the fifth limit tube 82 and the sixth limit tube 83 are located between the two positioning components 1, the fifth limit tube 82 and the sixth limit tube 83 with different lengths can be used to limit the second load-bearing wheel 6, thus preventing the second load-bearing wheel 6 from moving left and right on the third shaft 81.
