Good effect of the present utility model be its have rational in infrastructure, be easy to make, assemble the features such as simple and convenient, the three position gears especially realizing reverse shift fork with simple structure slide, realize at each gear the function such as real-time monitoring of self-locking and reverse shift fork displacement; Compact overall structure of the present invention, conserve space, make whole gearbox structure simpler, be easier to processing.
Accompanying drawing explanation
Fig. 1 is structural drawing of the present utility model.
Fig. 2 is reverse shift fork local structural graph of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further: a kind of odd-side is the AMT gear box sub-case gear shifting cylinder of two intermediate shaft structure, it is characterized in that: displacement transducer 4 is fixedly connected in the induction groove of cylinder block 7 casing wall side, solenoid valve 11 is fixedly connected on cylinder block 7 casing wall opposite side, selector fork axle 8 front end penetrates cylinder block 7 inner chamber, main piston 6 is arranged in cylinder block 7 inner chamber, main piston 6 front end is fixedly connected with selector fork axle 8 front end by tightening nut 3, the spacing steel ball 10 that main piston 6 rear end and selector fork axle 8 pass through on selector fork axle 8 is spacing, in gearbox main box body locating and machining hole, steel backing composite bush 9 is fitted in speed changer main box body and cylinder block 7 rear end positioning hole respectively, selector fork axle 8 rear end has self-locking grooves and self-locking spring 16, self-locking steel ball 14 forms self-locking device, reverse shift fork 13 is connected by clamping bolt 15 with selector fork axle 8, induction magnetic patch 5 is embedded on main piston 6, cylinder head 1 is covered and is tightly connected in cylinder block 7 front end and cylinder block 7, cylinder head 1 and cylinder block 7 joint limited location catch 2, sub-piston 12 is arranged in cylinder head 1.
When cylinder assembly is installed, one end of declutch shift shaft 8 is inserted in gearbox main casing, realizes the two end supports of declutch shift shaft 8, better can ensure that the installation precision of 13 forks is dialled in gear shift, increases its working life.In gearbox main box body locating and machining hole, and in declutch shift shaft 8 rear end processing self-locking grooves, make itself and self-locking spring 16 and self-locking steel ball 14 be combined into self-locking device, this device can realize the auto-lock function of reverse shift fork at each gear.Reverse shift fork 13 with change to declutch shift shaft 8 and be connected by clamping bolt, structure is simple, be convenient to dress changes.
For making main piston 6 accurately can get back to central idle position, require that the sliding stroke of sub-piston 12 is greater than main piston 6 and slides the half of total kilometres.Like this when cylinder A chamber passes into gas, sub-piston 12 slides to the right, then promote now to slide to the right at the main piston 6 of left side gear, stop when sub-piston 12 slides into limited location snap ring 2 position sliding, sub-piston 12 sliding stroke is the half of the total sliding stroke of main piston 6, and now main piston 6 plunks in the middle neutral position; When cylinder B chamber air inlet and A chamber leads to air time, promoting the leftmost side while main piston 6 slides sub-piston 12 being back into cylinder to the right.This structure makes main piston 6 reliably can be returned to bit positions, not easily produces phenomenon not in place, and thus reset reliability is higher.
The present invention is directly contained in controlling the solenoid valve of gas on cylinder, has two gas circuits to be connected with the gas circuit of solenoid valve the both sides of main piston in also direct access cylinder body, control the turnover of gas in cylinder.Such a configuration reduce unnecessary pipeline, make cylinder entirety compacter.
For strengthening the using effect of matching property between main piston 6 outer wall and cylinder inner wall and lubricating grease, process 2 groups of oil grooves at main piston 6 outer wall, lubricating grease is more evenly distributed, and working efficiency is higher.
As shown in accompanying drawing 1, accompanying drawing 2, embed induction magnetic patch 5 in main piston 6 and pour into epoxy resin, at temperature 140 DEG C, solidifying 2 hours; After main piston 6 and declutch shift shaft 8 add spacing steel ball, O shape ring, be assembled together by tightening nut 3; Declutch shift shaft 8 also forms axial sliding fit with it through the steel backing composite bush embedded in cylinder-bore, and main piston 6 assembles two O shape rings and can slide axially in cylinder block 7.
Limit stoper is the limited location snap ring 2 be arranged between cylinder block 7 and cylinder head 1.Stop when main piston 6 slides into limited location snap ring 2 left, stop when sliding into cylinder inner cavity bottom surface to the right, between stroke be the gear shift stroke of left and right two grades.
Resetting means is the sub-piston 12 be arranged in cylinder head cavity, requires that the sliding distance of sub-piston 12 is not less than the half of gear shift stroke.Promote main piston 6 to the right to slide to the right when sub-piston 12 slides simultaneously, stop to during limited location snap ring 2 place, the stroke now promoting main piston 6 slip is the half of left and right two speed shift strokes, is namely parked in central idle position.
