[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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.

[0024] The utility model solves the problem that the looseness or deformation caused by load changes affects the stability and safety of agricultural machinery vehicles, poses a safety risk, and the vibration and impact force generated cause large noise. Figure 1-Figure 4 The energy-saving large agricultural machinery vehicle transmission device shown includes a first transmission shaft 1 and a second transmission shaft 2. The outer periphery of the end of the first transmission shaft 1 is annular and evenly fixed with multiple square blocks 11. A through hole 21 is opened in the middle of the second transmission shaft 2. The inner wall of the through hole 21 is annular and evenly opened with multiple slide grooves 22. The square blocks 11 are slidably connected with the corresponding slide grooves 22. The square blocks 11 are flexible metal sheets; the agricultural machinery vehicle transmission device, during the driving of the agricultural machinery vehicle, the agricultural machinery vehicle drive shaft needs to withstand pressure from all directions, including bending moment and torque. The agricultural machinery vehicle drive shaft is used to ensure the normal operation of the agricultural machinery vehicle, and at the same time can also make it more stable and safe during driving.

[0025] In the present invention, the first transmission shaft 1 is fixedly connected to a short shaft 12 at one end away from the square block 11, and the end of the short shaft 12 is fixedly connected to a first universal joint fork 13; the short shaft 12 helps connect the first transmission shaft 1 with the first universal joint fork 13, and the first universal joint fork 13 can be a device connected to other transmission devices.

[0026] It should be noted that a second universal joint fork 27 is fixedly connected to one end of the second transmission shaft 2, and a plurality of sealing plugs 24 are provided at the other end of the second transmission shaft 2. A refueling hole 25 is provided on one side of the oil chamber 23, and a sealing plug 24 is installed inside the refueling hole 25; the sealing plug 24 is a sealing structure for the oil chamber 23. When the lubricating oil in the oil chamber 23 is less and needs to be added, the sealing plug 24 is opened, and the staff adds lubricating oil from the refueling hole 25.

[0027] It should also be noted that a mounting ring 26 is slidingly provided on the outer periphery of the first transmission shaft 1. The mounting ring 26 is installed on one side of the inner portion of the through hole 21. The mounting ring 26 is located between the short shaft 12 and the square block 11. The mounting ring 26 helps to fix the first transmission shaft 1 and the second transmission shaft 2, and at the same time can help limit the square block 11 so that it does not slide out of the slide groove 22, thereby ensuring the normal operation of the transmission device.

[0028] In the present invention, when the transmission device is subjected to pressure, the first transmission shaft 1 slides in the through hole 21 of the second transmission shaft 2, and the first transmission shaft 1 drives the square block 11 to move, and the square block 11 slides in the slide groove 22, thereby ensuring the stability of the agricultural machinery vehicle. Since the square block 11 is a flexible metal sheet, its good elasticity and toughness can provide additional supporting force, which helps to ensure that the first transmission shaft 1 remains stable during the sliding process in the second transmission shaft 2, prevents loosening or deformation due to load changes or vibrations, and ensures the stability and safety of the agricultural machinery vehicle.

[0029] Furthermore, since the square block 11 is a flexible metal sheet, it can absorb and disperse part of the vibration and impact, thereby reducing the noise caused by the vibration and impact.

[0030] Furthermore, the provision of the flexible metal sheet of the square block 11 can form a lubricating layer between the square block 11 and the slide groove 22, thereby reducing direct contact and friction between them, which helps to reduce the wear rate and extend the service life of the transmission device.

[0031] It should be noted that the square block 11 is a flexible metal sheet and can be made of spring steel or other materials, and the specific material is not limited.

[0032] When the cam 22 is in a state of being moved along the longitudinal axis 23 , the oil in the cam 22 is moved along the longitudinal axis 23 , so that the oil in the cam 22 is moved along the longitudinal axis 23 , so that the oil in the cam 22 is moved along the longitudinal axis 23 .

[0033] Furthermore, the addition of lubricating oil can make the transmission process smoother and significantly reduce vibration and noise caused by friction.

[0034] It should be noted that the square block 11 is in active contact with the two elastic sheets 3 in the corresponding oil chamber 23 , and the elastic sheets 3 are normally located inside the slide groove 22 .
