Mouth T-phase is logical, and power assisted gearshift system and gas source separate and lose power assisted gearshift.By this mode, front hanging is allowed to keep off arc convex 12
Starting point and neutral gear position groove 11 slot bottom central point between with shifting shaft 6 be the central angle size in the center of circle, it is same with synchronizer
The power-assisted of power assisted gearshift system, can be terminated opportunity control in synchronization by the corresponding shifting shaft rotation angle automatching setting of walking journey
After the synchronizing process of device, and before synchronizer gear sleeve is engaged with gear ring.Shelves and the principle and mistake to front hanging shelves are hung backward
Cheng Xiangtong, details are not described herein.The present invention realizes the accurate control for terminating opportunity to power-assisted, solves prior art synchronizer
The problem of by power assisted gearshift continuous action and causing secondary pulse improves the comfort and portability of shift, ensure that synchronization
The safety and reliability of device.It should be noted that in practical applications, front hanging gear arc convex 12 and after put into gear arc convex
13 be symmetrical structure, and make front hanging gear arc convex 12 and after put into gear that arc convex 13 is corresponding and the two sidewalls of neutral gear position groove 11
It is connected smoothly, to enhance the ride comfort and continuity hanging shelves and trigger the movement of mandril 4 in the process.
As specific embodiment, if the clearance distance between 31 lower end of contact pilotage of trigger switch 3 and triggering 4 upper end of mandril
It is indicated with x, the line in slot bottom central point a to 6 axle center of shifting shaft of neutral gear position groove 11 indicates that the length of m1 is with r1 table with m1
Show, the line in starting point b to 6 axle center of shifting shaft of front hanging gear arc convex 12 indicates that the length of m2 is indicated with r2 with m2, m2 and m1
Between angle indicate that (front hanging is kept off between the starting point b of arc convex 12 and the slot bottom central point a of neutral gear position groove 11 to change with α
Gear shaft 6 is the central angle in the center of circle), the present invention should allow r2-r1-x=y, and wherein y indicates the triggering stroke of trigger switch 3, so that touching
The lower end for sending out mandril 4, which is moved to trigger switch 3 when front hanging keeps off the starting point of arc convex 12 from neutral gear position groove 11, reliably to trigger
It connects, and allows α-Δ α=θ, wherein Δ α is 1 °~2 °, and θ indicates that the corresponding shifting shaft of the synchronized stroke of synchronizer rotates angle,
To guarantee that the power-assisted of power assisted gearshift system terminates opportunity after the synchronizing process of synchronizer and in synchronizer gear sleeve and gear ring
Before engagement, effectively prevents generating collision when power assisted gearshift causes synchronizer gear sleeve to engage with gear ring and secondary pulse shows
As.In addition, if the line in terminal c to the shifting shaft axle center of front hanging gear arc convex 12 is indicated with m3, the angle between m2 and m1
Indicate that (front hanging is kept off between the terminal c of arc convex 12 and the slot bottom central point a of neutral gear position groove 11 with shifting shaft 6 as the center of circle with β
Central angle), the present invention usually allows β >=δ, and wherein δ expression is put into gear the corresponding shifting shaft rotation angle of stroke, to put into gear before guaranteeing
Arc length between the starting point b and terminal c of arc convex 12 meets the requirement for stroke of putting into gear.It should be noted that the present invention is usual
α is designed as 12 °~15 °, β is designed 20 °~25 °, to match synchronized stroke and the corresponding shifting shaft rotation angle of stroke of putting into gear
Degree can adapt to adjustment according to specific synchronizer and gearshift in practical applications.
As prioritization scheme, present embodiment, which passes through, allows the pilot hole peripheral wall in triggering mandril 4 and fixing seat 2 to slide
Cooperation has made to trigger the air channel 41 axially disposed on the peripheral wall of mandril 4, steady axially movable in enhancing triggering mandril 4
On the basis of property, the operating sensitivity and precision of gas-cutting off device in advance are improved.And the lower end of triggering mandril 4 is allowed to use spherical surface
Head allows the upper end of triggering mandril 4 to use tack, to enhance the ride comfort and continuity of its movement to guarantee it to contact pilotage 31
The reliability of press.Meanwhile present embodiment is by allowing 3 spinning of trigger switch to be arranged on the upside of pilot hole in fixing seat 2
Threaded hole in, improve the convenience of dismounting, and it is octagonal so that trigger switch 3 in the upper side position of fixing seat 2 is provided with limit
First 32, roll adjustment gasket 33 is provided between limit octagonal head 32 and fixing seat 2, by the roll adjustment gasket 33 for selecting different-thickness
Spacing between adjustable contact pilotage 31 and triggering mandril 4, improves the scope of application of gas-cutting off device in advance.In addition, the present invention allows
The slot bottom of neutral gear position groove 11 uses flat formation, to simplify structure and preparation process.
It should be noted that in the present invention front hanging gear arc convex 12 and after the put into gear crowning of arc convex 13 be to change
Gear shaft is the cylinder in axle center.The above content essentially describe front hanging gear arc convex 12 and when putting into gear forward to power-assisted at the end of
The control process of machine, arc convex 13 of then putting into gear are to be arranged with front hanging gear arc convex 12 in symmetrical structure, are put into gear backward
Process is identical with process of putting into gear forward.
Above embodiments are only the descriptions carried out to the preferred embodiment of the present invention, and model not is claimed to the present invention
