Problems solved by technology
Although the height difference device disclosed in this patent has a compact structure and is more convenient to use, due to the effect of gravity, a torque will be generated on the left and right connecting pipes, although the height difference device realizes the rocker arm through a set of worm and gear devices. The swing self-locking, but this torque acts on this worm gear device for a long time, which will affect its service life
At the same time, the structure of the height difference device is too complicated, and the manufacturing cost is relatively high

Embodiment Construction
[0014] An improved tractor driving wheel differential height device, such as figure 1 with figure 2 As shown together, it includes a left rocker arm 3 and a right rocker arm 3' that can also be used as a final transmission case. The first end and the second end surround the outer peripheral surfaces of the left power output half shaft 11 and the right power output half shaft 11 ′. A left final drive 9 and a right final drive 9 ′ are respectively provided between the left power output half shaft 11 and the right power output half shaft 11 ′ and the left drive wheel 4 and the right drive wheel 4 ′, which can be chain drives, It can also be a belt drive or a gear drive or the like.
[0015] The left support sleeve 6 surrounds the outer peripheral surface of the left power output shaft 11 and is fixed to the gearbox case 1 , and the second end of the left rocker arm 3 is sheathed on the outer peripheral surface of the left support sleeve 6 . The right support sleeve 6' surroun...

The invention discloses an improved tractor drive wheel differential height device, which includes a left rocker arm and a right rocker arm that can also be used as a final drive box, and the second end of the left rocker arm is rotatable around the left power drive The outer peripheral surface of the output half shaft, the second end of the right rocker arm is rotatable around the outer peripheral surface of the right power output half shaft; it also includes a lever hinged to the tractor frame, and hinged to the tractor frame and the hydraulic cylinder between the lever, said lever is arranged transversely along the tractor frame, one end of which is hinged with the left rocker arm through the first connecting rod, and the other end is hinged with the right rocker arm through the second connecting rod. The invention has the advantages of simple structure, low manufacturing cost, and reasonable stress on each component, and can be suitable for use in mountainous or hilly areas with large slopes through direct simple transformation on the basis of existing walking tractors.
Description
technical field [0001] The invention relates to the technical field of tractors, in particular to a device capable of adjusting the relative heights of two driving wheels of the tractor. Background technique [0002] The left and right driving wheels of most known walking tractors are fixed on the same axis, and the relative height of the left and right driving wheels cannot be adjusted with the gradient of the walking area. It is suitable for small slope operations, but cannot be used in mountainous or hilly areas with large slopes. Chinese patent CN1579121A discloses a mountain tractor, which drives the left and right connecting pipes surrounding the outer peripheral surfaces of the left and right power output shafts to rotate in opposite directions at the same time through a set of height difference device arranged in the gearbox, and the rotation of the left and right connecting pipes makes it fixedly connected The rocker arm rotates around the axis of the power output ...
