Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work Every other embodiment obtained, fall within the protection scope of the utility model.

Fig. 1-5 is please referred to, the utility model provides a kind of technical solution: a kind of tractor Special shifting fork, including connecting shaft Set 1, connection pin shaft 3, shift fork arm 4, shift fork connector 5, limits clamping plate 6, limit card slot 7, fixing bolt 8 and fixes link block 2 Nut 9, the downside of connecting bushing 1 is fixed with link block 2, and the lower end of link block 2 is equipped with connection pin shaft 3, connection pin shaft 3 Outside is connected with shift fork arm 4, and the lower end of shift fork arm 4 is fixed with shift fork connector 5, and the outside of shift fork arm 4 is connected with position limiting clamp Plate 6, and limit clamping plate 6 and be located at 5 upside of shift fork connector, it limits and offers limit card slot 7 on clamping plate 6, and limit card slot 7 is interior Portion is connected with fixing bolt 8, and the front end of fixing bolt 8 is through shift fork arm 4 and limit clamping plate 6, and the outer end of fixing bolt 8 connects There is fixture nut 9.

It is integrated between connecting bushing 1 and link block 2, and the middle position of 2 inside of link block is through slot structure, And the through slot direction of 2 inside of link block and the port direction of connecting bushing 1 are perpendicular, it is ensured that the operation is stable of the shift fork Performance, and it is possible to prevente effectively from because the activity of shift fork arm 4 is driven the adverse effect of work to shift.

Inside the upper end insertion link block 2 of shift fork arm 4, and the upper end of shift fork arm 4 passes through connection pin shaft 3 and 2 structure of link block At rotational structure, thus it is possible to vary the size of the shift fork improves the use value of the shift fork.

It is integrated between shift fork connector 5 and shift fork arm 4, and the thickness of shift fork connector 5 is greater than shift fork arm 4 Thickness, and the inside of shift fork connector 5 be arcuate structure, facilitate the shift fork to be installed on gearshift, enhance the shift fork with The stability of gearshift connection.

The centre for limiting clamping plate 6 is upper lower port structure, and the port width for limiting 6 inside of clamping plate is equal to shift fork arm 4 Thickness, position limiting clamp plate 6 can be made to play restriction effect to shift fork arm 4, to reinforce 4 stability under working conditions of shift fork arm.

Fixing bolt 8 includes nuts 801, fixture block 802 and threaded rod 803, and the outside of nuts 801 is fixed with fixture block 802, and the outside of fixture block 802 is fixed with threaded rod 803, fixture block 802 is square prism type, and fixture block 802 is with limit card slot 7 It is connected together, stable adjusting work can be carried out to the size between shift fork arm 4 by limit clamping plate 6 and fixing bolt 8, mentioned The high use high efficiency of the shift fork.

Working principle: when using the tractor Special shifting fork, firstly, first the size of the shift fork to be adjusted, make The shift fork, which can be stablized, to be installed on gearshift, then when adjusting the size of the shift fork, first by fixing bolt 8 from 4 He of shift fork arm It is disassembled on limit clamping plate 6, due to not having the fixation of fixing bolt 8, shift fork arm 4 can connected by connecting pin shaft 3 It is rotated on block 2, to change the size between 2 shift fork arms 4；

At this point it is possible to connecting bushing 1 is connected on the shifting shaft of gearshift, and shift fork arm 4 can be connected by shift fork First 5 are stuck on the driven gear of gearshift, after shift fork connector 5 is connect with driven gear, fixing bolt 8 can be worn Shift fork arm 4 and limit clamping plate 6 are crossed, while the fixture block 802 on fixing bolt 8 needs to be stuck in the limit card slot 7 on limit clamping plate 6 It is interior, after 2 shift fork arms 4 are connect with fixing bolt 8 and fixture nut 9, by limit clamping plate 6 fix 2 shift fork arms 4 it Between size can pass through the shift fork later and push driven tooth to make shift fork connector 5 is stable to be stuck on driven gear Wheel, to complete shift work；

When unexpected situation occurs in the shift fork, fixing bolt 8 can be removed in the manner described above, it can be by shift fork Arm 4 and driven gear separate, and disassemble the shift fork from gearshift to facilitate, later, can be in the manner described above The shift fork more renewed guarantees the efficient working condition of gearshift, is the use process of the shift fork above, and in this specification The content being not described in detail belongs to the prior art well known to professional and technical personnel in the field.
