In.When neutral gear position, interlocking plunger 7 and shift fork axle 8 all have groove facing at steel ball.Move when a certain selector fork and
When putting into gear, another selector fork is just fixed on neutral gear position by interlock and can not move axially.
Such as Fig. 1, single axle gearshift mechanism of automotive transmission of the present utility model, including shift fork axle sleeve 1, three/tetra-gear self-lockings
Pin assembly 2, three/tetra-gear gear shifting pulling heads 3, one/bis-gear gear shifting pulling head 4, one/bis-gear self-lock pin assembly 5, one/bis-gear selector fork
6, interlocking plunger 7, shift fork axle 8, three/tetra-gear selector forks 9, linear bearing 10, interlock steel ball 11.
Described shift fork axle sleeve 1, three/tetra-gear self-lock pin assemblies 2, one/bis-gear self-lock pin assembly 5 is fixedly installed in change speed gear box
On housing.
One/bis-described gear gear shifting pulling head 4, three/tetra-gear gear shifting pulling heads 3 are driven by paired shift motor.
One/bis-described gear selector fork 6 is sheathed on shift fork axle 8 by linear bearing 10, and shift motor drives one/bis-
Gear gear shifting pulling head 4 promotes one/bis-gear selector fork 6 to move on shift fork axle 8, and when arriving neutral or one/bis-gear, one/bis-gear changes
Keeping off three axially distributed grooves of shift fork 6 upper surface must have just to be directed at one/bis-gear self-lock pin assembly 5.
Three/tetra-described gear selector forks 9 are fixing with shift fork axle 8 to be connected, and shift motor drives three/tetra-gear gear shifting pulling heads 3
Three/tetra-gear selector forks 9 are promoted to move axially together with shift fork axle 8, when arriving neutral or three/tetra-gears, shift fork axle 8 upper surface
Three axially distributed grooves must have one to be just directed at three/tetra-gear self-lock pin assemblies 2.
It is linked into two gears, design interlocking between one/bis-gear selector fork 6 and shift fork axle 8 during for ensureing variator difference
Device, it is ensured that can move axially at same time only one of which shift fork.Interlock is mainly by interlocking plunger 7 and interlocking steel ball 11
Composition, interlocking plunger 7 is fixedly installed on one/bis-gear selector fork 6, and interlocking steel ball 11 is loaded in the longitudinal hole of gear box casing.
When neutral gear position, interlocking plunger 7 and shift fork axle 8 all have groove facing at steel ball.When one/bis-gear selector fork 6 moves
And when putting into gear, shift fork axle 8 is just fixed on neutral gear position by interlock together with three/tetra-gear selector forks 9 and can not move axially；
When three/tetra-gear selector forks 9 move together with shift fork axle 8 and put into gear, it is fixed on by interlock once/bis-gear selector forks 6
Neutral gear position and can not move axially.
Upshift process is as follows:
Fig. 1 is this utility model single axle gearshift mechanism of automotive transmission neutral position state.
With reference to Fig. 2, when gearshift is linked into a gear from neutral, shift motor drives one/bis-gear gear shifting pulling head 4 to promote

Selector fork 9 is just fixed on neutral gear position and can not move axially, when shift sensor detects that one/bis-gear gearshift is dialled in real time
When fork 6 puts in place, motor stalls.
With reference to Fig. 3, when gearshift is linked into two gears from a gear, shift motor drives one/bis-gear gear shifting pulling head 4 to promote
One/bis-gear selector fork 6 is moved to the left, and first arrives neutral gear position, is further continued for being moved to the left, and now interlocking steel ball 11 is in shift fork
In the groove of axle 8, shift fork axle 8 is just fixed on neutral gear position together with three/tetra-gear selector forks 9 and can not move axially, and works as gear
Level sensor detects when one/bis-gear selector fork 6 puts in place in real time, motor stalls.
With reference to Fig. 4, when gearshift is linked into three gears from two gears, shift motor drives one/bis-gear gear shifting pulling head 4 to promote
One/bis-gear selector fork 6 moves right arrival neutral gear position, another shift motor drive three/tetra-gear gear shifting pulling heads 3 promote three/
Four gear selector forks 9 move right together with shift fork axle 8, and now interlocking steel ball 11 is in the groove of interlocking plunger 7, and one/bis-
Gear selector fork 6 is just fixed on neutral gear position and can not move axially, when shift sensor detects three/tetra-gear gearshifts in real time
When shift fork 9 puts in place, motor stalls.
With reference to Fig. 5, when gearshift is linked into four gears from three gears, shift motor drives three/tetra-gear gear shifting pulling heads 3 to promote
Three/tetra-gear selector forks 9 are moved to the left together with shift fork axle 8, arrive neutral gear position, are further continued for being moved to the left, now interlock
Steel ball 11 is in the groove of interlocking plunger 7, is fixed on neutral gear position once/bis-gear selector forks 6 and can not move axially, when
Shift sensor detects when three/tetra-gear selector forks 9 put in place in real time, motor stalls.
Downshift process is similar with upshift process, therefore repeats no more.
Have employed the single axle gearshift mechanism of automotive transmission in this utility model, structurally use a shift fork axle,
One of them selector fork is fixing with shift fork axle to be connected, and another one selector fork is sheathed on shift fork axle, can realize relatively dialling
Moving axially of fork shaft, each selector fork is furnished with a gear shifting pulling head；For ensureing that variator can not be linked into two gears simultaneously,
Being designed with interlock between shift fork axle and the selector fork that relative movement can occur therewith, this utility model eliminates block selecting
Operating process, improves shift speed, makes shift time shorten, improve the power interruption of AMT vehicle, have wider application
Scope.
