Effect is realized self-locking；The function of the self-locking top grade, when being guaranteed at top grade, gearbox is not in failure out of supply.
Referring to fig. 4, Fig. 4 is that the gear of the gear box sub-case cylinder of the invention with power takeoff is in the structure of middle area
Figure, interlocking power taking and puts into gear that detailed process is as follows for operation:
Gearbox main tank carries out hanging neutral gear operation, and compressed air enters middle area 05 through corresponding port, pushes second piston 5
Mobile, the compressed air in low-grade area is discharged through corresponding port；
Power take-off valve is opened, compressed air enters high-grade area 06 by corresponding port through vehicle solenoid valve, pushes first
Piston 4 is mobile until being in contact with positioning ring 12；
Gear box sub-case carries out drag-down operation, and the corresponding port of compressed air enters to low-grade area 04, pushes second piston 5
Mobile, 05 compressed air of middle area is discharged through corresponding port, and cylinder is in middle area 05 at this time, puts into gear and is not suspended to position；
When cylinder is in middle area 05, mutual blocking valve 10 is corresponding with interlocking apertures 13, and interlocking gas circuit is opened, at this time odd-side
It cannot put into gear.
After main tank is linked into neutral position state, odd-side can just shift gears, and main tank neutral gear is to keep vehicle stopped state, and odd-side changes
Gear and opening power take-off valve are to guarantee that auxiliary box cylinder is in middle area 05, and odd-side gear state is that gear is not suspended to position at this time,
I.e. main tank can not shift gears；Odd-side gear not in place and piston 2 is not in minimum or highest state, self-locking mechanism be not implemented from
Lock, odd-side gear is unstable, and shift fork axle has axial movement, easily causes out of supply, and auxiliary box synchronizer is caused to damage), interlock gas circuit
Predominantly realize that main tank and odd-side are mutually protected, mutually restrict function.Mutual blocking valve and master of the auxiliary box cylinder installation with interlocking apertures
The gas path control valve connection of case shift control, under main tank neutral position state (main tank gas path control valve is died, i.e., interlock valve is died,
Without air pressure, positioned at interlocking apertures 13 interlock valve mandril without lateral resistance when, auxiliary box cylinder can realize that high and low shift switches).Similarly, main
Case is gas circuit ventilation when putting into gear state, interlock valve mandril and interlocking apertures tight fit, and limitation shift fork axle 3 moves axially, i.e. limitation is secondary
Case shift is realized mutually protection, is mutually restricted.
The gear box sub-case cylinder with power takeoff when force taking of parking, not only prevents main tank due to increasing interlocking structure
It puts into gear, while improving the reliability and service life of auxiliary box cylinder, be conducive to the normal work of auxiliary box synchronizer；Increase simultaneously
Self-locking mechanism, prevents synchronizer from losing rank, improves the reliability and service life of auxiliary box cylinder, be conducive to auxiliary box synchronizer
It works normally.
The above content is merely illustrative of the invention's technical idea, and this does not limit the scope of protection of the present invention, all to press
According to technical idea proposed by the present invention, any changes made on the basis of the technical scheme each falls within claims of the present invention
Protection scope within.
