Embodiment 1

[0018] Such as figure 1 and figure 2 As shown, the four-wheel tractor ground clearance adjusting lifting system of the present invention includes a front wheel ground clearance adjusting lifting system and a rear wheel ground clearance adjusting lifting system. Such as figure 1 As shown, the front wheel ground clearance adjustment lifting system includes an upper box body 1 and a lower box body 20 , both of which are airtight, and the lower box body 20 is arranged below the upper box body 1 . The casing flange 4 on the side of the upper casing 1 facing the front wheel drive shaft is docked with the tractor front-drive steering wheel flange, and the tractor front-drive steering wheel flange is fixedly connected with the tractor front-drive steering component 2, so when the tractor turns, the tractor front-drive turns Part 2 can drive the upper box body 1 to turn. Bevel gear III 22 and bevel gear IV 23 are arranged inside the upper box 1, the shaft intersection angle of beve...

Embodiment 2

[0030] The difference from Embodiment 1 is that in this embodiment, the rear wheel ground clearance adjustment lifting system is connected to the steering component, and at this time, its box body flange 4 is docked with the tractor front drive steering wheel flange, and the bevel gear IV The hub of the tractor is connected to the drive shaft, and the drive shaft is docked with the tractor rear wheel drive disc.

[0031] Others are with embodiment 1.

Embodiment 3

[0033] The difference from Embodiment 1 is that in this embodiment, the ground clearance adjusting lifting system is a front wheel ground clearance adjusting lifting system, that is, no ground clearance adjusting lifting system is provided at the rear wheels. The ground clearance adjusting lifting system can also be a rear wheel ground clearance adjusting lifting system, that is, no ground clearance adjusting lifting system is provided at the front wheels.

[0034] Others are with embodiment 1.

Abstract

The invention relates to the field of vehicle transmission device arranging or installing, and in particular to a ground clearance adjusting lifting system of a four-wheel tractor. The ground clearance adjusting lifting system comprises a closed upper tank and a closed lower tank. The upper tank is located above the lower tank. The ground clearance adjusting lifting system further comprises a lifting rod. The upper tank and the lower tank are connected through the lifting rod. A tank flange is arranged on one side edge of the upper tank, and a fixing base is arranged on the corresponding other side edge of the upper tank. The upper tank is internally provided with a third bevel gear and a fourth bevel gear. The crossed axis angle of the third bevel gear and the fourth bevel gear is 90 degrees. The third bevel gear and the fourth bevel gear are engaged. The fourth bevel gear is fixedly connected with a drive shaft. The third bevel gear is in sliding connection with the lifting rod. After the system is installed on the four-wheel tractor, the ground clearance of the four-wheel tractor can be greatly increased and can be freely adjusted.

Description

technical field [0001] The invention relates to the field of arrangement or installation of a vehicle transmission device, in particular to a lifting system for adjusting the ground clearance of a four-wheel tractor. Background technique [0002] At present, the number of four-wheel tractors produced in my country is already very large, but the ground clearance of existing tractors is fixed and very limited, and their application in agricultural production has great limitations. [0003] With the rapid development of my country's agriculture, in my country's current agricultural production, there are more and more requirements for tractors. It is required that tractors can not only realize the functions of general tractors, but also be able to connect with receiving machinery suitable for high straw crops. Drug spraying machinery, chemical fertilizer spraying machinery, etc., not only expand the adaptability of tractors, but also save money and resources. But at this time, w...
