Train of reduction gears transmitting rotary power, so as to moving gear F39 and the driving cog 41 1 being embedded in gear F39 centre bores
Play rotation.1. when left output shaft assembly 5 engages knot simultaneously with the internal tooth 17 of the clutch ring 16 of right output shaft assembly 6 with driving cog 41
During conjunction, the gear F39 of rotation drives clutch ring 16 to rotate indirectly, and because clutch ring 16 the side of internal tooth 17 further through steel ball 15
It is slidably connected with clutch axle sleeve 13, when gear F39 rotates, you can drive both sides output axle shaft 10, then drive left and right two
Individual crawler driving whell 12 rotates simultaneously, by gear box structure configuration on the agricultural tool of crawler type, it may be achieved directly to row
Walk；2. directly into operation process, when the steering in left side makees rotate counterclockwise 22, rotating shaft 21 drives the steering fork in left side
20 rotate, and force clutch ring 16 to be slid to the left along the axial direction of clutch axle sleeve 13, make the right side of 16 internal tooth of clutch ring 17 and driving cog 41
Left side external tooth implements separation, and then left output axle shaft shuts down, and right output axle shaft continues the state of rotation, configures small
On the caterpillar agricultural tool of type, left-hand turning walking can be achieved in the presence of right output axle shaft power；Similarly, 3. work as right side
Steering when being turned clockwise 22, right output axle shaft shuts down, and left output axle shaft continues to rotate, and configures in small-sized caterpillar belt
Dextrad turning walking can be achieved after the agricultural tool of formula in the presence of left output axle shaft power；4. it is same, in operation process,
When left side steering 22 with the steering on right side 22 respectively by it is counterclockwise, rotate clockwise when, then the clutch of the right and left
Enclose 16 internal tooths 17 to be kept completely separate with the external tooth of driving cog 41, realize both sides output axle shaft 10 while shut down, otherwise, in both sides bullet
In the presence of spring 18, internal tooth 17 and the external tooth of driving cog 41 of clutch ring 16 are in engagement all the time, configure in crawler type
Agricultural tool after, the operation such as can implement directly to march forward and stop, and this steering mechanism part is rational in infrastructure, novel in design, turns to
Flexibly, noise is low, easy to operate, can be widely applied to crawler type agricultural machinery all weather operations.
