Description
Technical field
The invention belongs to the tractor selector device, be 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 is provided with two one control lever A, B, takes vertically horizontal vertical arrangement side by side, be operating handle among the operating handle A, gearshift axle and connection set between the two, spatially be arranged vertically mutually often.Operating handle among the same operating handle B, gearshift axle and connection set between the two, spatially also vertically arranged mutually 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 big, the cost of production height.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.
Summary of the invention
Technical problem to be solved by this invention provides 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 invention, comprise first operating handle and 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 first thumb wheel in the described protective housing side by side, 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 first driving lever that is nested together, second driving lever, link together by key between the 3rd driving lever and the 4th driving lever, each thumb wheel and corresponding driving lever.
Because technique scheme adopts first operating handle, second operating handle to stir four thumb wheels that have U-shaped groove, realize shifting by four driving levers that have shifting block that are nested together again, the entire mechanism compact structure, gear is more simultaneously, mechanical efficiency is high, cost is very low, easy-to-operate; Four thumb wheels that have U-shaped groove are arranged side by side together, and are connected by key with four driving levers that are provided with shifting block and are nested together successively and have been that it is little to take up room, thereby save cost of production.

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