The invention discloses an improved height difference adjusting device for driving wheels of a tractor, which comprises left and right rocker arms which double as final drive boxes, and the left and right rocker arms respectively have first ends installed on the left and right drive wheels, and the second ends surrounding the outer peripheral surfaces of the left and right power output half shafts of the main gearbox of the tractor, the second ends of the left and right rocker arms are respectively rotatably surrounding the left and right power output half shafts Outer peripheral surface, it also includes a rocker arm driving device installed on the frame and controlling the synchronous reverse swing of the left and right rocker arms, the output shaft of the main gearbox and the input of the rocker arm driving device A power transmission device is provided between the shafts. The present invention can be directly transformed on the basis of the existing walking tractor, has simple structure and low manufacturing cost, and is suitable for use in mountainous or hilly areas with large slopes.
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 relative height of the left and right driving wheels cannot be adjusted according to the gradient of the walking area. Slope operations, but can not 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 half shaft, so that the ...
