Detailed Implementation

[0025] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0026] See Figure 1 , Figure 2 , Figure 3 and Figure 5 Because existing tractor frames are integral frames, the entire frame needs to be disassembled when repairing and maintaining the components mounted on it. The disassembly and installation of the frame is time-consuming, labor-intensive, and inefficient. Therefore, this utility model provides a tractor frame, including a track connecting frame 1, an engine frame 2, and a generator mounting frame 3. The track connecting frame 1 is used to install the tractor's track assembly 81. The engine frame 2 is detachably connected to the track connecting frame 1 and to the tractor's engine 82. The generator mounting frame 3 is used to install the tractor's generator 83 and is detachably connected to the engine 82. The engine 82 and the generator 83 are connected in a transmission connection, and the output end of the generator 83 is connected in a transmission assembly. The track connecting frame 1 of this utility model can install the track assembly 81 of the tractor, the engine frame 2 can install the engine 82 of the tractor, and the generator mounting frame 3 can install the generator 83 of the tractor. This allows the tractor components to be installed in the corresponding positions on the tractor frame, and the tractor frame can effectively support and install the components installed on the tractor frame. Furthermore, the track connecting frame 1 and the engine frame 2, the engine frame 2 and the engine 82, and the engine 82 and the generator mounting frame 3 are all detachably connected, changing the structure of the tractor frame from an integral type to a segmented type, improving the flexibility of the tractor frame. When a component on the frame needs repair or maintenance, only the corresponding frame structure needs to be disassembled, making the disassembly and installation of the tractor more time-saving and labor-saving, and with high installation and maintenance efficiency. At the same time, there is no connection between the generator mounting frame 3 and the engine frame 2. The engine 82 connects the engine frame 2 and the generator mounting frame 3, allowing the engine frame 2 and the generator mounting frame 3 to be disassembled independently. This also reduces the vibration or impact caused by the direct connection between the engine frame 2 and the generator mounting frame 3, and reduces the stress on the engine frame 2 and the generator mounting frame 3.

[0027] To enable detachable connections between the various frame structures within the tractor frame, the tractor frame also includes a bolt assembly. This bolt assembly connects the track connecting frame 1 and the engine frame 2, the engine frame 2 and the engine 82, and the engine 82 and the generator mounting bracket 3. Compared to welding in existing tractor frame technologies, the bolt assembly reduces weld seams and deformation, effectively overcoming the problems of deformation and stress concentration encountered during welding. Furthermore, it improves the efficiency of disassembling and installing the track connecting frame 1, engine frame 2, and generator mounting bracket 3.

[0028] See Figures 1 to 3 To improve the structural stability of the track connecting frame 1, the tractor frame also includes a connector 4, which connects the track connecting frame 1 and the tractor's safety frame 5. By connecting the track connecting frame 1 and the safety frame 5, the connector 4 effectively prevents deformation of the track connecting frame 1, improves its structural stability, and enhances the rigidity and strength of the vehicle body.

[0029] In one implementation, the connector 4 is detachably connected to the track connecting frame 1 and the safety frame 5.

[0030] To enable the detachable connection between the connector 4 and the track connecting frame 1 and the safety frame 5, one end of the connector 4 is connected to the track connecting frame 1 via a bolt assembly, and the other end of the connector 4 is connected to the safety frame 5 via a U-bolt.

[0031] See Figures 1 to 3 In some embodiments, the track connecting frame 1 includes a left track connecting frame 11 and a right track connecting frame 12, both of which are detachably connected to the engine frame 2.

The connection between the left track connecting frame 11 and the right track connecting frame 12 and the engine frame 2 makes the tractor frame connection more robust.

[0032] In some embodiments, the left track connecting frame 11 and the right track connecting frame 12 are connected to the engine frame 2 by bolt assemblies.

[0033] See Figure 1 In some embodiments, the track left connecting frame 11 includes a left mounting plate 111, a left support rod 112, and a left connecting pipe 113.

The connection between the left mounting plate 111 and the engine frame 2 enables the track left connecting frame 11 to be connected to the engine frame 2. The left connecting pipe 113 effectively supports the left mounting plate 111 and the left support rod 112, ensuring the stability of their relative positions, thereby achieving the fixed installation of the track assembly 81.

[0034] In some embodiments, the left support rod 112 is arranged perpendicularly to the left mounting plate 111, and the left mounting plate 111, the left support rod 112 and the left connecting pipe 113 are fixedly connected by welding.

[0035] In some embodiments, the left support rod 112 is an angle steel and the left connecting pipe 113 is a rectangular tube.

The two ends of the left connecting member 41 are detachably connected to the left track connecting frame 11 and the safety frame 5, respectively. The two ends of the right connecting member 42 are detachably connected to the right track connecting frame 12 and the safety frame 5, respectively. The left connecting member 41 and the right connecting member 42 prevent deformation of the left track connecting frame 11 and the right track connecting frame 12, increasing the rigidity and strength of the vehicle body.

[0040] In some embodiments, the left connector 41 is connected to the left track connector 11 via a bolt assembly and to the safety frame 5 via a U-bolt; the right connector 42 is connected to the right track connector 12 via a bolt assembly and to the safety frame 5 via a U-bolt.

[0041] See Figure 1 and Figure 3 To ensure the stability of the relative positions of the left connecting member 41 and the right connecting member 42, the tractor frame also includes a track connecting frame crossbeam 6. The track connecting frame crossbeam 6 is positioned between the left track connecting frame 11 and the right track connecting frame 12, and both ends of the track connecting frame crossbeam 6 are detachably connected to the left connecting member 41 and the right connecting member 42, respectively. By connecting the left connecting member 41 and the right connecting member 42, the track connecting frame crossbeam 6 effectively ensures the stability of their relative positions and prevents displacement of the left connecting member 41 and the right connecting member 42.

[0042] In some embodiments, the track connecting frame crossbeam 6 is connected to the left connecting member 41 and the right connecting member 42 by bolt assemblies, thereby improving the efficiency of disassembly and installation.

[0043] See Figure 3 In some embodiments, the engine frame 2 includes an engine frame body and multiple engine mounting seats 24. The engine frame body is detachably connected to the left track connecting frame 11 and the right track connecting frame 12. The multiple engine mounting seats 24 are detachably connected to the engine frame body and are also detachably connected to the engine 82. The engine frame body is used to mount the engine 82 and effectively support it. The multiple engine mounting seats 24 connect the engine frame body and the engine 82, allowing the engine 82 to be detachably mounted on the engine frame body. Furthermore, the arrangement of the multiple engine mounting seats 24 makes the connection between the engine frame body and the engine 82 more stable.

[0044] In some embodiments, the engine frame body includes an engine frame crossbeam 23, a left longitudinal beam 21, and a right longitudinal beam 22. The engine frame crossbeam 23 is detachably connected to the left track connecting frame 11 and the right track connecting frame 12. The left longitudinal beam 21 is fixedly connected to the engine frame crossbeam 23, and the right longitudinal beam 22 is fixedly connected to the engine frame crossbeam 23.

[0045] In some embodiments, the engine frame crossbeam 23, left longitudinal beam 21, and right longitudinal beam 22 are fixedly connected by welding, thereby improving the structural stability of the engine frame body.

[0046] In some embodiments, multiple engine mounts 24 are detachably mounted on the left longitudinal beam 21 and the right longitudinal beam 22, and the engine mounts 24 are used for detachable connection with the engine 82.

[0047] In some embodiments, four engine mounting brackets 24 are provided, which are symmetrically arranged on the left longitudinal beam 21 and the right longitudinal beam 22, and are connected to the left longitudinal beam 21 and the right longitudinal beam 22 by bolt assemblies.

[0048] See Figure 2 and Figure 4In some embodiments, the generator mounting frame 3 includes a front generator frame 31 and a rear generator frame 32. One side of the front generator frame 31 is detachably connected to the housing of the engine 82, and the other side of the front generator frame 31 is detachably connected to the generator 83. The rear generator frame 32 is detachably connected to the front generator frame 31. The front generator frame 31 is detachably connected to the housing of the engine 82, thus connecting to the engine frame 2. The generator 83 is installed inside the front generator frame 31, and the rear generator frame 32 is installed on the front generator frame 31, thereby effectively protecting the generator 83. Furthermore, the detachable connection between the front generator frame 31 and the rear generator frame 32 makes the disassembly and installation of the generator 83 more convenient and easier to repair or maintain.

[0049] In some embodiments, engine 82 is a diesel engine, with the rear flywheel housing flange of the diesel engine bolted to the front generator frame 31, and generator 83 connected to the diesel engine via splines.

[0050] In some embodiments, the generator 83 is mounted on the front generator frame 31 by bolt assemblies, and the front generator frame 31 and the rear generator frame 32 are fixedly connected by bolt assemblies to form the generator mounting bracket 3.

[0051] See Figure 4 To achieve a detachable connection between the rear generator frame 32 and the front generator frame 31, the rear generator frame 32 includes a rear annular plate 321, and the front generator frame 31 includes a front annular plate 311, multiple connecting rods 312, and a connecting annular plate 313. The front annular plate 311 is detachably connected to the generator 83. One end of each connecting rod 312 is fixedly connected to the front annular plate 311, and the connecting annular plate 313 is fixedly connected to the other end of each connecting rod 312 and detachably connected to the rear annular plate 321. The front annular plate 311 can be connected to the engine 82 via bolt assemblies and can also mount the generator 83. The connecting rods 312 not only form a space with the front annular plate 311 and the connecting annular plate 313 to accommodate the generator 83, but also prevent the generator 83 from being damaged by external forces. The connecting annular plate 313 can be connected to the rear annular plate 321, so that the generator mounting frame 3 forms a frame structure, effectively protecting the generator 83 inside the generator mounting frame 3.

[0052] To form the front generator frame 31, the front annular plate 311, multiple connecting rods 312, and connecting annular plate 313 are fixedly connected by welding.

[0053] In some embodiments, the rear generator frame 32 further includes a clamping member 322 disposed on the rear annular plate 321, the clamping member 322 being used to clamp the generator 83 against the front annular plate 311. The clamping member 322, in cooperation with the front annular plate 311, ensures that the generator 83 is coaxially arranged with the front annular plate 311, effectively clamping the generator 83 and ensuring the stability of the relative position of the generator 83.

[0054] In some embodiments, the abutment 322 is a cylinder disposed on the rear annular plate 321, which can pass through the through hole of the connecting annular plate 313 and abut against the generator 83 mounted on the front annular plate 311.

[0055] See Figure 1 , Figure 2 , Figure 3 and Figure 5 In some embodiments, the tractor frame also includes two rear axle connecting frames 7, which are detachably connected to the generator mounting frame 3 via a PTO gearbox 84. The rear axle connecting frames 7 are connected to the transmission assembly. The connection between the two rear axle connecting frames 7 and the generator mounting frame 3 via the PTO gearbox 84 achieves an integral connection of the tractor frame, ensuring its integrity, facilitating easy assembly and disassembly, simplifying the structure, and enabling the rear axle connecting frames 7 to connect to the transmission assembly.

[0056] In some implementations, the two rear axle connecting frames 7 are symmetrically arranged on the left and right sides of the PTO gearbox 84, which facilitates connection with other mechanically powered agricultural implements and improves the working stability of the implements.

[0057] See Figure 1 , Figure 3 and Figure 5 The rear axle connecting frame 7 includes a motor guard plate 71, a first mounting plate 72, and a second mounting plate 73. The motor guard plate 71 is detachably connected to the wheel-side motor 85.

The first mounting plate 72, located on one side of the motor guard plate 71, can be connected to the PTO gearbox 84, thereby connecting the generator mounting frame 3 and the rear axle connecting frame 7. The second mounting plate 73, located on the other side of the motor guard plate 71, can mount the reducer 87 onto the rear axle connecting frame 7, thus achieving the drive connection between the wheel-side motor 85 and the reducer 87.

[0058] In some embodiments, the motor guard plate 71 has an arc-shaped cross-section along the length of the tractor frame. The arc-shaped motor guard plate 71 can effectively fix the position of the wheel-side motor 85, prevent the wheel-side motor 85 from shifting, and effectively protect the wheel-side motor 85.

[0059] In some embodiments, the motor guard plate 71, the first mounting plate 72, and the second mounting plate 73 are fixedly connected by welding to form a complete rear axle connecting frame 7.

[0060] In some implementations, the PTO gearbox 84 is fixed to the generator mounting bracket 3 by bolts, and the PTO gearbox 84 is connected to the two rear axle connecting brackets 7 by bolt assemblies.

[0061] See Figure 3 and Figure 5 To enable a detachable connection between the wheel-side motor 85 and the rear axle connecting frame 7, the rear axle connecting frame 7 also includes a wheel-side motor mounting base 74. The wheel-side motor mounting base 74 is detachably installed within the motor guard plate 71 and detachably connected to the wheel-side motor 85. The wheel-side motor mounting base 74 securely mounts the wheel-side motor 85 within the motor guard plate 71, making the installation of the wheel-side motor 85 and the motor guard plate 71 more convenient.

[0062] In some embodiments, the wheel-side motor 85 is mounted on the wheel-side motor mounting base 74 by bolt assembly, and the wheel-side motor mounting base 74 is mounted inside the motor guard plate 71 by bolt assembly.

[0063] To connect the reducer 87 to the rear axle connecting frame 7, the rear axle connecting frame 7 also includes a reducer mounting plate 77. The reducer mounting plate 77 is detachably mounted on the second mounting plate 73 and detachably connected to the reducer 87. By mounting the reducer mounting plate 77 on the second mounting plate 73 and then mounting the reducer 87 on the reducer mounting plate 77, the reducer 87 can be mounted on the rear axle connecting frame 7, and a detachable connection between the reducer 87 and the rear axle connecting frame 7 can be achieved.

[0064] To achieve a detachable connection between the reducer 87 and the reducer mounting plate 77, the reducer 87 and the reducer mounting plate 77 are connected by a bolt assembly, and the reducer mounting plate 77 is connected to the second mounting plate 73 by a bolt assembly.

[0065] See Figure 5 The wheel-side motor 85 and the reducer 87 are connected by a brake 86. A spline sleeve is installed inside the brake 86. The output shaft of the wheel-side motor 85 passes through the spline sleeve of the brake 86 and is connected to the spline in the reducer 87. When braking, the output shaft of the wheel-side motor 85 is engaged to impede movement and perform the braking function. The brake 86 is fixed to the reducer mounting plate 77 by bolts.

[0066] In some implementations, the PTO gearbox 84, the two rear axle connecting frames 7, and the reducer 87, reducer mounting plate 77, brake 86, and wheel-side motor 85 mounted on the rear axle connecting frames 7 form the rear drive axle of the tractor, improving the strength and rigidity of the tractor chassis, making the tractor chassis structure simple, safe and reliable, easy to maintain and repair, and reasonably arranged.

[0067] To mount implements onto the tractor frame, the tractor frame also includes a three-point suspension lower lever mounting base 75 and a three-point suspension limit rod mounting plate 76. The three-point suspension lower lever mounting base 75 is fixedly connected to the first mounting plate 72 by welding, and the three-point suspension limit rod mounting plate 76 is fixedly connected to the outside of the motor guard plate 71 by welding. The cooperation of the three-point suspension lower lever mounting base 75 and the three-point suspension limit rod mounting plate 76 enables the suspension of the three-point suspension device, which is safe, reliable, and easy to assemble and disassemble. The three-point suspension device is used to connect implements. The three-point suspension device allows implements to be supported at three connection points behind the tractor, thereby improving the overall balance and stability and reducing the tractor's swaying and tilting during operation. The use of the three-point suspension device makes the connection and adjustment of implements more convenient and quick, which can greatly improve the efficiency and productivity of operation and reduce the labor and time costs in the agricultural production process.

[0068] This utility model also provides a tractor, which includes the tractor frame of any of the above-described embodiments. The tractor frame is a segmented frame, with each frame structure connected by bolts, reducing welds and effectively overcoming the problems of deformation and stress concentration during welding. Furthermore, it allows components such as the track assembly 81, engine 82, generator 83, PTO gearbox 84, wheel-side motor 85, brake 86, reducer 87, and three-point suspension to be installed in corresponding positions on the tractor frame, improving the efficiency of frame maintenance.

[0069] To improve the stability of the tractor, the track assembly 81, engine 82, generator 83 and PTO gearbox 84 are arranged longitudinally along the tractor frame, which improves the longitudinal stability of the tractor; the reducer 87, brake 86, wheel-side motor 85 and PTO gearbox 84 are arranged transversely along the tractor frame, which improves the lateral stability of the tractor.

[0070] The tractor frame of this utility model is applicable to hybrid electric tractors. It is designed with a frame structure to fix and support the track assembly 81, engine 82, generator 83, PTO gearbox 84, reducer 87, brake 86, wheel-side motor 85 and three-point suspension device that need to be installed on the tractor frame, so that the above components can be installed in reasonable relative positions on the tractor frame.
