With the 4th inclined-plane 31 or the first inclined-plane 24 and third inclined-plane 29.
6 sets of the left clutch component 2 of the left clutch, left clutch-plate 3, left bearing 4, spacer 6, left bearing 4 and spacer
It is located on gear bush 1, left clutch component 2 is rotatably arranged on babinet, and left clutch-plate 3 is hinged on babinet, one end
Coordinate with 4 end face of left bearing, the other end coordinates with the convex block on left clutch component 2, and 6 end face of spacer is tightly attached to 13 end face of left cap
On；The right clutch component 8 of the right clutch, right clutch-plate 10, right bearing 11, right bearing 11 are set on gear shaft 12,
Right clutch component 8 is rotatably arranged on babinet, and right clutch-plate 10 is hinged on babinet, and one end is matched with 11 end face of right bearing
It closes, the other end coordinates with the convex block on right clutch component 8, and 11 end face of right bearing is tightly attached on 9 end face of right cap.The left and right
Resetting spring 5 is connected between clutch-plate 3,10.
In order to reduce left and right brake spring 17,19 frictional resistance, the gear wheel 7 by gear bush 18 rotationally
It is arranged on gear shaft 12, left and right spring mounting groove, left and right brake spring 17,19 is formed between gear wheel 7 and gear bush 18
It is corresponding to be mounted in the spring mounting groove of left and right.
In order to effectively prevent dust, the further scheme of the invention, the left and right side cap 13,9 and gear wheel 7 it
Between be correspondingly provided with seal washer 33.
The invention operation principle is as follows：When left and right clutch is in off position, as shown in figure 4, left and right
There are larger clutch gap 22 between side cover 13,9 and left and right middle cover 15,20, the side cover disk tooth 14 on left and right side cap 13,9
Clutch state is in the intermediate shrouding disc tooth 21 in left and right middle cover 15,20, when gear wheel 7 rotates under drive gear drive
When, because intermediate shrouding disc tooth 21 is with side cover disk tooth 14 with not engaging, left and right middle cover 15,20 will not drive left and right side cap 13,9 to revolve
Turn, therefore left and right side cap 13,9 will not drive gear bush 1, gear shaft 12 to rotate.
When left and right clutch is in running order, left and right clutch component 2,8 by convex block drive left and right clutch-plate 3,
10 work compress left and right bearing 4,11, and left bearing 4 compresses left cap 13 by spacer 6, and right bearing 11 compresses right cap 9, left and right
Side cover 13,9 left and right clutch active force push under overcome left and right brake spring 17,19 elastic force respectively with left and right middle cover
15th, 20 engagement, by identical thrust, the first plane 25 and second of left and right clutch block 16,34 is flat for left and right middle cover 15,20 both sides
30 closed butt joint of face.When small ploughs is controlled to move forward or back, gear wheel 7 passes through left and right clutch under drive gear drive
The first and second facades 23,27 and the third and fourth facade 28,32 on block 16,34 drive left and right middle cover 15,20 to rotate, left
Right middle cover 15,20 is corresponded to by left and right side cap 13,9 and drives 12 synchronous rotary of gear bush 1 and gear shaft, so as to fulfill advance
Or it retreats.
When being turned to the left by steering external force, as shown in fig. 7, right wheel speed is faster than revolver speed and generates speed discrepancy,
The first plane 25 and the second plane 30 of left and right clutch block 16,34 cannot keep docking and generate dislocation, on left clutch block 16
Second inclined-plane 26 is docked with the 4th inclined-plane 31 on right clutch block 34, and the common work for acting power is combined in steering force and inclined-plane
Clutch gap 22 is generated with bottom right middle cover 20 and right cap 9 and realizes clutch, right middle cover 20 and the independent rotation of right cap 9,
Left middle cover 15 is engaged with left cap 13, and gear wheel 7 drives left cap 13 to rotate by left middle cover 15, and left cap 13 passes through tooth
Axle sleeve 1 drives revolver rotation, so as to fulfill the differential turned to the left；After turning, left and right wheel speed restores consistent, in right
Between lid 20 combine the collective effect for acting power on right 19 elastic force of brake spring and inclined-plane under automatically reset, right cap 9 with it is right
Middle cover 20 engages, and the left and right clutch block 16,34 in left and right middle cover 15,20 restores the first plane 15 and the second plane 30 is right
It connects, is restored to normal forward or backward state.
When being turned to the right by steering external force, as shown in figure 8, revolver speed is faster than right wheel speed and generates speed discrepancy,
The first plane 25 and the second plane 30 of left and right clutch block 16,34 cannot keep docking and generate dislocation, on right clutch block 34
Third inclined-plane 29 is docked with the first inclined-plane 24 on left clutch block 16, and the common work for acting power is combined in steering force and inclined-plane
Clutch gap 22 is generated with bottom left middle cover 15 and left cap 13 and realizes clutch, left middle cover 15 and the independent rotation of left cap 13
Turn, right middle cover 20 is engaged with left cap 9, and gear wheel 7 drives right cap 9 to rotate by right middle cover 20, and right cap 9 passes through tooth
Wheel shaft 12 drives right wheel rotation, so as to fulfill the differential turned to the right；After turning, left and right wheel speed restores consistent, left
Between lid 15 combine the collective effect for acting power on left 17 elastic force of brake spring and inclined-plane under automatically reset, left cap 13 with it is left
Middle cover 15 engages, and the left and right clutch block 16,34 in left and right middle cover 15,20 restores the first plane 15 and the second plane 30 is right
It connects, is restored to normal forward or backward state.
One embodiment of the above, only the invention, not makes in any form the invention
Limitation, on the basis of the technical solution of the invention is not departed from, made simple modification, equivalent variations or modification are fallen
Enter the protection domain of the invention.
