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
[0017] Mechanical height difference adjustment of tractor drive wheels, e.g. figure 2 As shown, it includes left and right rocker arms 3, 3' which can also be used as final drive boxes, and the left and right rocker arms 3, 3' have first ends mounted on left and right drive wheels 4, 4' respectively , and the second ends surrounding the outer peripheral surfaces of the left and right power output half shafts 11, 11'. Left and right final transmission devices 7 and 7' are respectively arranged between the left and right power output half shafts 11 and 11' and the left and right driving wheels 4 and 4', which can be chain transmission devices or belt transmission devices or gear transmission etc.
[0018] The left support sleeve 6 surrounds the outer peripheral surface of the left power output half shaft 11 and is fixed to the case body 12 of the gearbox. The second end of the left rocker arm 3 is sheathed on the outer peripheral surface of the left support sleeve 6 . The rig...

The invention discloses a mechanical height difference adjusting device for driving wheels of a tractor, which comprises left and right rocker arms which also serve as final drive boxes. The left and right rocker arms respectively have first end, and the second end around the outer peripheral surface of the left and right power output half shafts of the tractor gearbox, the second ends of the left and right rocker arms are respectively rotatably around the left and right power output half shafts It also includes a rotatable pivot mounted transversely on the tractor frame, and a transmission device connected to the input shaft of the tractor gearbox and capable of driving the pivot; and when the pivot rotates The rocker arm driving device can make the left and right rocker arms rotate in opposite directions respectively. The present invention has simple structure and low manufacturing cost, and can be suitable for use in mountainous or hilly areas with relatively large gradients by directly carrying out 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 tractors are fixed on the same axis, and the height of the left and right driving wheels cannot be adjusted according to the gradient of the walking area. It is easy to rollover when walking laterally on slopes, and it is only suitable for flat land or slopes with small slopes. operations, but not 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 fixed...
