Technical Field

[0001] The utility model belongs to the technical field of crawler gears, in particular to a 16+16 transmission system with crawler gears. Background Art

[0002] Currently, common tractors are equipped with a crawler gear transmission structure, in which two pairs of gears are specially set behind the auxiliary gearbox to reduce the speed. Since the arrangement of the two pairs of gears is limited by the structure and the center distance between the two axles, it is difficult to reduce the speed to the required 0.25kM / h. In many cases, this speed is 0.35kM / h, and the problem of trenching not meeting the standards often occurs. This problem also plagues the design of the tractor crawler gear.

[0003] To solve the above technical problems, according to the patent document entitled "A Novel Crawler Gear Structure" with authorization announcement number CN218845001U, the structure includes a housing, an output shaft movably connected to the housing, an input shaft, and an intermediate shaft. The circumferential side wall of the output shaft is fixedly connected to a first gear, the circumferential side wall of the output shaft is movably connected to a first meshing sleeve and a third gear in sequence from left to right, and the circumferential side wall of the output shaft is fixedly connected to a fifth gear and a seventh gear in sequence from left to right. However, the following defects still exist:

[0004] Its crawler gear structure only uses a simple structure of gears meshing with each other, which cannot effectively adjust the reduction ratio and improve the load-bearing conditions. Utility Model Content

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a 16+16 transmission system with a crawler gear, comprising a transmission mechanism, a crawler gear assembly being provided in the transmission mechanism, a gear shaft being provided in the crawler gear assembly, and a small gear and a large gear being provided on the outside of the gear shaft.

[0007] Preferably, the transmission mechanism includes a reverse gear assembly, one side of the reverse gear assembly is connected to the forward gear assembly, one side of the forward gear assembly is connected to the first gear assembly, one side of the first gear assembly is connected to the second gear assembly, one side of the second gear assembly is connected to the third gear assembly, one side of the third gear assembly is connected to the fourth gear assembly, the fourth gear assembly is connected to a resist assembly, and one side of the resist assembly is connected to the middle gear assembly.

[0008] Preferably, a high-gear component is provided between the fourth-gear component and the resisting component.

[0009] Preferably, the crawler gear assembly is connected to a side of the middle gear assembly away from the resisting assembly.

[0010] Compared with the prior art, the beneficial effects of the present invention are:
