One end of the cab mechanism 30 is detachably connected to the mounting frame 8, and the other end is detachably connected to the chassis assembly. The cab mechanism 30 is installed through the protective frame 4 and has a covered space inside. The drive axle assembly 101, heat dissipation assembly 102, counterweight assembly and chassis assembly are all located in the covered space.

[0046] This embodiment designs a chassis fixture that improves the stability of tractor component transportation by orderly and detachably mounting various tractor components onto the bottom support plate 1. Simultaneously, the centralized stacking method reduces the overall space occupancy of tractor components, improves space utilization for boxed transportation, and lowers shipping costs. It should be noted that, as... Figure 1 As shown, the length direction of the bottom support plate 1 is the front-to-back direction in the figure, and the width direction of the bottom support plate 1 is the left-to-right direction in the figure.

[0047] like Figure 2 As shown, in this embodiment, the counterweight assembly includes a first counterweight 201 and a second counterweight 202 arranged at intervals along the width direction of the bottom support plate 1. A rear mounting space is formed between the first counterweight 201 and the second counterweight 202. The chassis assembly includes a main body 203 and a mounting part 204 integrally connected. The main body 203 of the chassis assembly is disposed in the rear mounting space and is detachably connected to the bottom support plate 1. The mounting part 204 is located behind the counterweight assembly.

[0048] In this embodiment, by placing the counterweight assembly and chassis assembly at the rear end of the bottom support plate 1, the balance of each tractor component placed on the bottom support plate 1 can be achieved, preventing the bottom support plate 1 from tilting forward due to excessive tractor components, which would affect the stability of tractor component transportation. Furthermore, the first counterweight 201 and the second counterweight 202 are arranged at intervals along the width direction of the bottom support plate 1, which ensures the weight balance of the tractor components on the bottom support plate 1 in the left-right direction.

[0049] like Figure 1 and Figure 2 As shown, in this embodiment, the chassis fixture further includes a first mounting bracket and a second mounting bracket 3 installed at the rear end of the bottom support plate 1. The first mounting bracket includes a left bracket 21 and a right bracket 22 spaced apart along the width direction of the bottom support plate 1. Both the left bracket 21 and the right bracket 22 are welded to the bottom support plate 1. The left bracket 21 is used for detachable connection with the first counterweight 201. The top end of the right bracket 22 has a first limiting groove for the second counterweight 202 to be locked in place, so as to prevent the second counterweight 202 from slipping off the right bracket 22. The second mounting bracket 3 is located on the side of the counterweight assembly away from the drive axle assembly 101. The top end of the second mounting bracket 3 has a second limiting groove for the mounting part 204 to be locked in place, so as to limit the mounting part 204 and prevent the mounting part 204 from slipping off the second mounting bracket 3.

[0050] In this application, the top of the left support 21 is provided with four limiting posts 211, which can be inserted and engaged with the first counterweight 201 to prevent the first counterweight 201 from slipping off the left support 21. Furthermore, the top of each limiting post 211 is provided with a fastener. By detachably connecting the fastener to the limiting post 211, the first counterweight 201 can be stably locked onto the left support 21, preventing it from slipping off. It should be noted that the number of limiting posts 211 can be adjusted according to actual needs.

[0051] like Figure 2 As shown, in this embodiment, the driving mechanism includes an oil tank 401 located between the second counterweight 202 and the drive axle assembly 101. By placing the oil tank 401 in the empty space at the top of the right bracket 22, the top space of the bottom support plate 1 is rationally utilized. The chassis fixture includes a locking device, which can stably lock the oil tank 401 onto the right bracket 22, preventing the oil tank 401 from slipping off the right bracket 22. The locking device can be made of a workpiece that is easy to disassemble, such as wire.

[0052] like Figure 2As shown, in this embodiment, the driving mechanism further includes an engine 402 and a bracket 403, which are spaced apart along the width direction of the bottom support plate 1. Specifically, as... Figure 1 As shown, bracket 403 is located on the left side of engine 402. Bracket 403 is detachably located between the first counterweight 201 and drive axle assembly 101. The bottom support plate 1 of the central mounting space has multiple mounting holes for the bracket 403 to be detached and installed. The bracket 403 can be detachably connected to the bottom support plate 1 with bolts, resulting in good installation stability.

[0053] like Figure 1 and Figure 4 As shown, in this embodiment, the driving mechanism further includes a first tire assembly 404, and the chassis fixture further includes a protective frame 4, a tie rod 5, and a limiting plate 6 disposed in the central mounting space. The first tire assembly 404 is placed on the top of the protective frame 4. The tie rod 5 is mounted on the protective frame 4 and extends towards the side of the protective frame 4 away from the engine 402. The tie rod 5 passes through the cavity in the middle of the tire for mounting the wheel hub to limit the first tire assembly 404 and prevent it from slipping off the protective frame 4. Furthermore, the limiting plate 6 can be detachably installed on the top of the tie rod 5. The limiting plate 6 is L-shaped and can stably lock the first tire assembly 404 onto the protective frame 4 to prevent it from slipping off the protective frame 4 during transportation due to bumps. The bracket 403 and the engine 402 are both located within the protective space of the protective frame 4 to reduce the impact damage to the bracket 403 and the engine 402 caused by external impacts.

[0054] The protective frame 4 includes a tire mounting bracket 42 and four outrigger welded components 41. All four outrigger welded components 41 are perpendicular to the bottom support plate 1. The tire mounting bracket 42 is welded to the top of the outrigger welded components 41 and together with the outrigger welded components 41 forms a protective space for the hood assembly 301, mitigating damage to tractor parts placed within the protective space when the container deforms due to impact. Furthermore, the protective frame 4 also includes multiple reinforcing rods 43, each with one end connected to the outrigger welded components 41 and the other end connected to the bottom support plate 1, to improve the overall structural strength of the protective frame 4.

[0055] like Figure 4 and Figure 5As shown, in this embodiment, the driving mechanism further includes a second tire assembly 405. The second tire assembly 405 is arranged at intervals on both sides of the protective frame 4 along the width direction of the bottom support plate 1. The chassis fixture also includes a locking member for locking the second tire assembly 405 onto the protective frame 4. Both the first tire assembly 404 and the second tire assembly 405 include two tires. The two tires in the first tire assembly 404 are stacked sequentially from top to bottom on the top of the protective frame 4. The two tires in the second tire assembly 405 are respectively arranged on opposite sides of the engine 402 and the bracket 403, i.e., one tire is locked onto the protective frame 4 on the left side of the bracket 403, and the other tire is locked onto the protective frame 4 on the right side of the engine 402. It should be noted that storage spaces are provided between the drive axle assembly 101 and the first counterweight 201, and between the drive axle assembly 101 and the fuel tank 401. This application achieves efficient utilization of the top space of the bottom support plate 1 by placing the two tires of the second tire assembly 405 into the storage spaces on the left side of the bracket 403 and the right side of the engine 402, respectively. Furthermore, this application also uses locking devices to lock the two tires to the left and right sides of the protective frame 4, respectively, to achieve stable installation of the two tires. This ensures the weight balance on the left and right sides of the protective frame 4 and improves the stability of tractor parts transportation. The locking devices can be cable ties for easy disassembly and installation.

[0056] like Figure 3 As shown, in this embodiment, the cab mechanism 30 includes a hood assembly 301 and a cab assembly 302. The mounting bracket 8 is located on the side of the drive axle assembly 101 away from the engine 402. The hood assembly 301 is detachably connected to the mounting bracket 8 and covers the engine 402 and the heat dissipation assembly 102. The cab assembly 302 is located above the counterweight assembly and the chassis assembly and is detachably mounted on the mounting portion 204 of the chassis assembly. The protective frame 4 forms a protective space for protecting the hood assembly 301 to reduce the impact damage to the hood assembly 301.

[0057] In this embodiment, the engine hood assembly 301 and the cab assembly 302 are relatively large and have a hollow structure, with a large covering space at their bottoms. The engine hood assembly 301 covers the engine 402 and the cooling assembly 102, protecting them while also making full use of the space above them, thus improving the overall compactness of the tractor components. Similarly, the cab assembly 302 covers the counterweight assembly and the chassis assembly, protecting them while also efficiently utilizing the space above them, further improving the overall compactness of the tractor components.

[0058] like Figure 1 As shown, in this embodiment, the chassis fixture also includes a limiting seat mounted on the bottom support plate 1. The limiting seat is located on the side of the drive axle assembly 101 away from the mounting frame 8, and the heat dissipation assembly 102 is detachably connected to the top of the limiting seat. Specifically, the limiting seat includes a connecting plate 71 and two limiting rods 72. Both limiting rods 72 are perpendicular to the bottom support plate 1. The two ends of the connecting plate 71 along its length are respectively connected to the side walls of the two limiting rods 72. A space is left between the connecting plate 71 and the bottom support plate 1 for part of the drive axle assembly 101 to extend into. The drive axle assembly 101 is detachably connected to the connecting plate 71 by bolts to ensure the stability of the drive axle assembly 101 during transportation. The heat dissipation assembly 102 is detachably connected to the top of the limiting rods 72. The heat dissipation assembly 102 is located above the drive axle assembly 101. Both the heat dissipation assembly 102 and the drive axle assembly 101 are located at the front end of the bottom support plate 1. The above installation method can achieve reasonable utilization of the front end space of the bottom support plate 1. The rear end of the bottom support plate 1 is equipped with a counterweight assembly and chassis components, ensuring the weight balance between the front and rear ends of the bottom support plate 1 and improving the stability of transporting tractor components.

[0059] like Figure 1 As shown, in this embodiment, the right bracket 22 extends outward from the bottom support plate 1 along its width direction, that is, the right bracket 22 extends to the right and forms an extension portion. A mounting plate 221 is also connected to the side of the extension portion of the right bracket 22 away from the second counterweight 202. The mounting plate 221 is located on the outer side of the bottom support plate 1 and extends downward. The silencing mechanism 50 is detachably connected to the mounting plate 221 to fully utilize the side space of the bottom support plate 1 and ensure that the tractor components are installed compactly. The height of the mounting plate 221 is lower than the height of the bottom support plate 1 to avoid direct contact between the mounting plate 221 and the ground.

[0060] It should be noted that during the packaging and transportation of tractor parts, once the tractor parts are installed on the bottom support plate 1, a forklift can be used to lift the bottom support plate 1 and place it into the container. Only the bottom support plate 1 contacts the bottom of the container, avoiding damage to the tractor parts during transfer and unpacking. Furthermore, in this embodiment, each tractor part can be compactly installed on the bottom support plate 1. By adopting the installation method of the tractor parts in this application, the overall space occupied by the tractor parts can be significantly reduced, effectively improving the space utilization rate of the container, reducing the shipping cost of the tractor parts, and enhancing the product's market competitiveness.
