Speed development, particularly recently as the developing of auto industry, the increase of inexpensive transportation demand, commercial car is to large-tonnage trend
Development.People propose vehicle mistake proofing safety, the reliability of critical component higher while automobile " Duola hurries up " is paid close attention to
It is required that.
Driver is often present with misplaced gear situation by mistake in drive routine, unexpected when driver's speed of operation is excessively high
1 gear is linked by mistake, can cause the damage of gear or entire gearbox.
The content of the invention
The utility model proposes a kind of quiet spools for commercial car heavy-duty power transmission solenoid valve, in order to solve
Movable valve plug can generate the locking power that enough electromagnetic forces overcome gearbox shifting shift fork, while coil block when being contacted with quiet spool
Movable valve plug being capable of quick separating with quiet spool after magnetic field disappears.
The technical solution of the utility model is therefore：A kind of quiet spool for commercial car heavy-duty power transmission solenoid valve,
It is characterized in that：
The end face of quiet spool is equipped with cooperation vestibule, and the bottom of vestibule is coordinated to be equipped with 2-5 and encloses snail line, plane spiral shell
The line width of spin line is 0.5-1.5mm, screw pitch 1-2mm, and the tapered past indent of snail line is V-shaped from radial section.
Preferably, quiet valve core material uses soft magnetic materials.
Preferably, the outer circumferential surface of quiet spool is preset with annular groove, the center of quiet spool is equipped with axially directed hole.
Advantageous effect：The bottom of the cooperation vestibule of quiet spool is equipped with the snail line of tapered past indent, makes valve
There are rational gap when core is contacted with quiet spool, and sped structure will not generate leakage field because of gap, so as to ensure movable valve plug
Magnetic leakage factor is minimum when being contacted with quiet spool, and the electromagnetic force of generation is maximum, overcomes the resistance of gearbox shifting block；
It is avoided in process using sped structure simultaneously because processing the flatness of the quiet spool end of influence；Spiral
Formula gap can effectively reduce the air drag that when being bonded generates of the movable valve plug with quiet spool, so that magnetic field after coil block power-off
Movable valve plug can quickly separate under the action of return spring power with quiet spool during disappearance.
Quiet valve core material uses soft magnetic materials, and material property is the generation induced electricity magnetic force under the action of having magnetic field, when
Induced electricity magnetic force quick disappearance when magnetic field disappears.
The outer circumferential surface of quiet spool preset annular groove facilitate installation sealing ring or with coil block clamping etc., axially directed hole root
It is configured according to function needs.

Specific embodiment
A kind of quiet spool for commercial car heavy-duty power transmission solenoid valve, the quiet spool be cylindrical structure, quiet spool
End face be equipped with cooperation vestibule 10B, coordinate vestibule bottom be equipped with 2-5 enclose snail line 10C, snail line 10C
Line width for 0.5-1.5mm, screw pitch 1-2mm, tapered past the indent of snail line, from radially seeing helical structure composition V-arrangement
Structure.
The material of the quiet spool uses soft magnetic materials.
The outer circumferential surface of the quiet spool is preset with annular groove 10D, and the center of quiet spool is equipped with axially directed hole 10A.
The specific implementation applied below for the utility model in a kind of commercial car gearbox high-speed response mistake proofing solenoid valve
Example：
A kind of commercial car gearbox high-speed response mistake proofing solenoid valve, including valve body, coil block and spool, valve body includes outer
Shell 1 and pedestal 3, shell 1 include upper cover function part 2, and the upper cover function part 2 of valve body is equipped with axially extending bore, and pedestal 3 is equipped with row
Stomata 4, gas vent is interior to be equipped with check valve 5；Coil block 6 is mounted in shell 1, is supported in the skeleton of coil block 6 every magnetic
Guide sleeve 7, the axially extending bore inner end of upper cover function part 2 are equipped with spring installation cavity, and the axially extending bore of upper cover function part 2 is slidably fitted with
Contact 8, spring installation cavity are equipped with reseting spring device 9；
Every being equipped with spool installation cavity in magnetic conductance set 7, the left side interference of spool installation cavity is equipped with quiet spool 10, right side slip
Movable valve plug 11 is installed, the left end interference of quiet spool 10 is installed on the inner end of upper cover function part 2, the quiet default ring of spool outer circumferential surface
