Description
Technical field
The utility model relates to a kind of tractor transverse axis speed-changing box pulling fork axle interlock.
Background technique
At present, Sichuan type transverse axis speed-changing box pulling fork axle is axial restraint on gearbox, and shift fork is located with holddown spring and steel ball on declutch shift shaft, on declutch shift shaft, move axially and carry out gear shift, when the tractor-drawn load is big, phenomenon out of supply might occur like this, cause human casualty accident.
Summary of the invention
It is not out of supply when traction load is big that the technical problems to be solved in the utility model provides a kind of tractor, normal engage a gear, gear shift, plucks a grade labour-saving transverse axis speed-changing box pulling fork axle interlock.
For solving the problems of the technologies described above, the utility model comprises gearbox, be provided with declutch shift shaft, shift fork in the gearbox, its structural feature is that described shift fork is fixed on the declutch shift shaft relevant position, on each gear relevant position of declutch shift shaft, be provided with " V " type groove, speed-changing box pulling fork axle top is provided with interlock body, and speed-changing box pulling fork axis hole top is provided with positioning hole, and described interlock body bottom is provided with the positioning hole of aforementioned positioning hole correspondence; In interlock body, be set with only rotating interlocking shaft, be provided with the locating stud that matches with described " V " type groove in the positioning hole between interlocking shaft and the declutch shift shaft, be processed with on the described interlocking shaft and the corresponding plat slot in described locating stud top, an axial end of interlocking shaft is installed with rocking arm, and rocking arm is connected with clutch pedal by rod assembly.
Be processed with the location curve bath on interlocking shaft, by the holding down bolt corresponding with curve bath position, described location it can only be rotated, this holding down bolt is fixed on described interlock body on the gearbox simultaneously.
In order to guarantee to hang up shelves, and only could engage a gear when neutral gear, be processed with curve bath at two axial end corresponding positions of declutch shift shaft, be provided with interlocking plunger between the two declutch shift shaft curve baths.
After adopting said structure, because two declutch shift shafts are provided with " V " type groove, be provided with locating stud in " V " type groove, and locating stud is locked it in " V " type groove of corresponding gear by interlocking shaft, even therefore tractor is not out of supply when traction load is big yet, and the rotation of interlocking shaft is driven by clutch pedal, only steps on clutch pedal just can carry out gear position operation, normal engage a gear, gear shift, to pluck shelves laborsaving, and safe in utilization.
