Description
Technical field
The utility model belongs to tractor shift steering mechanism, is specifically related to a kind of tractor bushing type compact type shift control mechanism.
Background technique
At present, the tractor shift control mechanism of domestic production, mostly be provided with two one control lever A, B, takes vertically horizontal vertical arrangement side by side, be operating handle in operating handle A, shifting shaft and connection set between the two, spatially mutually be arranged vertically often.Operating handle in same operating handle B, shifting shaft and connection set between the two, spatially also mutually vertically arranged often.And operating handle A and operating handle B often install side by side.Such tractor shift control mechanism part is more, and shared space is very large, and cost of production is high.In addition, because shift control mechanism medium tache is more, the mechanical transmission route is very loaded down with trivial details, and mechanical efficiency can reduce greatly, be prone to gearshift not in place, hang do not perform, the phenomenon of accidental shifting.
The model utility content
Technical problem to be solved in the utility model is to provide a kind of compact structure, gear is more, cost is very low, the tractor bushing type compact type shift control mechanism of easy-to-operate.
for solving the problems of the technologies described above, tractor bushing type shift control mechanism of the present utility model, comprise the first operating handle and the second operating handle that are provided with shifting block and limit pin hole, first, two operating handles are rack-mount by position limit pin respectively, the below of support is provided with bearing support and protective housing, be provided with side by side the first thumb wheel in described protective housing, the second thumb wheel, the 3rd thumb wheel and the 4th thumb wheel, be equipped with the U-shaped groove that connects for the operating handle shifting block on each thumb wheel, bearing support is provided with the first driving lever that is nested together, the second driving lever, the 3rd driving lever and the 4th driving lever, link together by key between each thumb wheel and corresponding driving lever.
Because adopting the first operating handle, the second operating handle, technique scheme stirs four thumb wheels with U-shaped groove, realize shifting by four driving levers with shifting block that are nested together again, whole mechanism structure is compact, and gear is more simultaneously, mechanical efficiency is high, cost is very low, easy-to-operate; Four thumb wheels with U-shaped groove are arranged side by side together, and with four driving levers that are provided with shifting block and are nested together successively, by key, are connected and have been, take up room little, thereby save cost of production.

Embodiment
Below in conjunction with accompanying drawing, the utility model tractor bushing type compact type shift control mechanism is described further;
by Fig. 1, Fig. 2, Fig. 3, Fig. 4 as seen, the utility model tractor bushing type compact type shift control mechanism, comprise the first operating handle 13 and the second operating handle 14 that are provided with shifting block and limit pin hole, first, two operating handles 13, 14 are arranged on support 10 by position limit pin 11 respectively, the below of support 10 is provided with bearing support 9 and protective housing 12, be provided with side by side the first thumb wheel 1 in described protective housing 12, the second thumb wheel 2, the 3rd thumb wheel 3 and the 4th thumb wheel 4, be equipped with the U-shaped groove that connects for the operating handle shifting block on each thumb wheel, bearing support 9 is provided with the first driving lever 5 that is nested together, the second driving lever 6, the 3rd driving lever 7 and the 4th driving lever 8, link together by key between each thumb wheel and corresponding driving lever.
The utility model is in when operation, and motionless when the second operating handle 14, namely the 3rd thumb wheel 3, the 4th thumb wheel 4 and the first driving lever 5, the second driving lever 6 are motionless, while namely all being in middle gear.To (insert to the right in the second thumb wheel 2 in the U-shaped groove of the shifting block of the first operating handle 13 insertion the first thumb wheel 1 or the second thumb wheel 2, insert left in the first thumb wheel 1) carry out block selecting, when the shifting block of the first operating handle 13 inserts to the right in the U-shaped groove of the second thumb wheel 2, stir forward or backward (being middle gear in the middle of being inserted in), just driving the second thumb wheel 2 rotates forward or backward, also rotate forward or backward with the 3rd driving lever 7 of the second thumb wheel 2 key connecting, the shifting block on the 3rd driving lever 7 is just stirred forward or backward gear in gearbox thereupon and is carried out the selection of two gearshifts thereupon.Insert left with shifting block that should the first operating handle 13 in the U-shaped groove of the first thumb wheel 1 while stirring forward or backward, also can carry out the selection of two gearshifts.
in aforesaid operations, if the second operating handle 14 also uses simultaneously, in inserting the U-shaped groove of the second thumb wheel 2, stirs forward or backward the shifting block of the first operating handle 13, while selecting gear forward or backward, (insert to the right in the 4th thumb wheel 4 in shifting block insertion the 3rd thumb wheel 3 of the second operating handle 14 or the 44 U-shaped groove, insert left in the 3rd thumb wheel 3) carry out block selecting, when the shifting block of the second operating handle 14 inserts to the right in the U-shaped groove of the 4th thumb wheel 4, stir forward or backward (being middle gear in the middle of being inserted in), just driving the 4th thumb wheel 4 rotates forward or backward, also rotate forward or backward with the second driving lever 6 of the 4th thumb wheel 4 key connecting thereupon, shifting block on the second driving lever 6 is just stirred forward or backward gear in gearbox thereupon and is carried out the selection of four gearshifts.Because this moment, the first operating handle 13 was stirred the second thumb wheel 2 forward, the second operating handle 14 is stirred the 4th thumb wheel 4 forward or backward the time, and two gears are arranged; Same the first operating handle 13 is stirred the second thumb wheel 2 backward, and the second operating handle 14 is stirred the 4th thumb wheel 4 forward or backward the time, produces again two gears; So far, can produce the gear of four selections.Same principle, when the shifting block of the second operating handle 14 inserts left in the U-shaped groove of the 3rd thumb wheel 3, stir forward or backward (being middle gear in the middle of being inserted in), just driving the 3rd thumb wheel 3 rotates forward or backward, also rotation forward or backward thereupon of the first driving lever 5 that connects with the 3rd thumb wheel 3 pin, the shifting block on the first driving lever 5 are just stirred forward or backward gear in gearbox thereupon and are carried out the selection of four gearshifts.
When the utility model is worked, some or severally be in forward, backward or neutral position in the first thumb wheel 1, the second thumb wheel 2, the 3rd thumb wheel 3 and the 4th thumb wheel 4, namely some in corresponding the first driving lever 5, the second driving lever 6, the 3rd driving lever 7 and the 4th driving lever 8 or severally be in forward, backward or during neutral position, the first manipulation bar 13 or the second manipulation bar 14 can carry out many kinds of gears and select.
The utility model is not limited to above-mentioned embodiment, and for example thumb wheel, driving lever can increase or reduce according to actual conditions, within all belonging to the utility model protection domain.
