The invention also discloses a kind of air brakes, use above-mentioned pneumatic brake cylinder.
The invention also discloses a kind of adjustment gap recognition methods, using pneumatic brake cylinder, referring to FIG. 10, including following
Step:
S1: in driving process, checking cylinder is braked, and the gap of braking does not adjust.
Specifically, filling wind to brake chamber 27 by 22 air inlet 29 of brake cylinder casing, 27 air pressure of brake chamber is increased, thus
Make piston 23 is pushed to compress and release spring 28 and be moved to the left, piston sleeve 11 successively push limit base 331, limit spring 333,
The first adjustment nut seat 312, the first adjustment nut 311 and lead screw 12, second adjustment module 32 is under the drive of lead screw 12
It is moved to the left together.In braking process, after the outer power limit certain by other structures outside checking cylinder of reset unit 1,
Limit spring 333 will continue to compress, until gapless between limit base 331, stop collar 332 and the first adjustment nut seat 312, this
When piston thrust successively by piston sleeve 11, limit base 331, stop collar 332, the first adjustment nut seat 312, the first adjustment nut
311, lead screw 12 passes to other structures outside checking cylinder.
S2: checking cylinder carries out release of brake after braking.
Specifically, the pressure air of brake chamber 27 is discharged by the air inlet 29 of brake cylinder casing 22, release spring 28 is multiple
Position elongation makes that piston 23 is pushed to move right, relieve a garrison before the drive of piston sleeve 11 swivel base 316, the first adjustment block 314, first
Adjusting nut 311 and lead screw 12 move right and reset, until the right side of piston 23 is pushed to contact with brake cylinder casing 22.
S3: since the abrasion of brake lining and brake disc keep brake clearance elongated, the first adjustment module 31, second adjustment module 32
The gap that the adjustment that cooperates is braked.
Specifically, the air inlet 29 by brake cylinder casing 22 fills wind to brake chamber 27,27 air pressure of brake chamber is increased, is pushed away
Piston 23 is compressed release spring 28 and is moved to the left, and piston sleeve 11 pushes limit base 331, limit spring 333, first to adjust according to this
Whole nut seat 312, the first adjustment nut 311 and lead screw 12.When guide pad 325 and stop collar contact, lead screw 12 still needs to move
Dynamic, second adjustment nut 321 continues to move to left under the drive of lead screw 12, and the movement of guide pad 325 is limited ring and is limited, at this time
Second adjustment spring 322 is compressed, the first cone tooth clutch pair between second adjustment nut 321 and second adjustment nut seat 323
326 disengage, and second adjustment nut 321 is rotated relative to lead screw 12, and lead screw 12 stretches out to the left with respect to second adjustment nut 321.When multiple
After outer power limit of the bit location 1 by other structures outside checking cylinder, limit spring 333 will continue to compress, until limit base
331, gapless between stop collar 332 and the first adjustment nut seat 312, at this time second adjustment nut 321 and second adjustment nut
The first cone tooth clutch pair 326 between seat 323 engages again.Push the thrust of piston 23 according to this by piston sleeve 11, limit base
331, stop collar 332, the first adjustment nut seat 312, the first adjustment nut 311 and lead screw 12 pass to other outside checking cylinder
Structure.
S4: the gap of adjustment 33 pairs of module adjustment of limit is identified and is made a response.
Specifically, not triggering adjustment limit module 33, gap tune when brake force is less than the distortional stress of limit spring 333
Whole to be normally carried out, brake force is transmitted to 333 front stall of limit spring, preceding adjusting nut and lead screw 12 by limit spring 333 and exports
To brake lining；When brake force is greater than the distortional stress of limit spring 333, limit spring 333 is compressed, and limit base 331 compresses limit
Ring 332, adjusting nut rotates after identification circle can not be rotated and be limited, between rear adjusting nut and second adjustment nut seat 323
Second cone tooth clutch pair 315 separates, and rear adjusting nut will not be moved with respect to lead screw 12, to avoid locking occurs.
S5: after identification module adjusts, checking cylinder carries out release of brake under new gap.
Specifically, the compressed air of brake chamber 27 is discharged by the air inlet 29 of brake cylinder casing 22, release spring 28 is multiple
Position elongation makes that piston 23 is pushed to move right, and relieve a garrison before the drive of piston sleeve 11 swivel base 316, the first adjustment block 314, first are adjusted
Whole nut 311, lead screw 12 move right and reset, and second adjustment module 32 also moves right together under the drive of lead screw 12,
When the first adjustment block 314 is limited by the guide groove end face on intermediate sleeve 21, the reset of lead screw 12 is terminated, and first adjusts
Whole nut 311 still continues to move to right under the drive of piston sleeve 11；The first adjustment spring 313 can be compressed at this time, make first
The second cone tooth clutch pair 315 between adjusting nut 311 and the first adjustment nut seat 312 disengages, and the first adjustment nut 311 is opposite
Lead screw 12 rotates, until pushing the right end face contact of piston 23 and brake cylinder casing 22, the first adjustment nut 311 and the first adjustment spiral shell
The second cone tooth clutch pair 315 between base 312 engages again.
In a further embodiment, gap can be adjusted by manually mode, referring to FIG. 7, rotation manual adjusts spiral shell
Mother 13, saddle type groups of springs 14 are separated from each other, 12 relative brake cylinder body 22 of lead screw to be compressed between precursor 15 and lead screw 12
Rotation is generated, so that 1 relative brake cylinder body 22 of reset unit be made to stretch out or retract, realization manually adjusts stretching for brake clearance length
Long or shortening.
By designing above, the setting adjustment limit module 33 between the first adjustment module 31 and second adjustment module 32,
The function of being identified during gap adjusts to the size of gap adjustment is realized, prevents locking caused by additionally adjusting existing
As improving travel safety；Piston guide circle 24 is set inside checking cylinder, makes to push piston 23 and brake cylinder casing 22 opposite
It is concentric, have the function of cleaning braking casing wall while improving sealing ring 26 and 22 fiting effect of brake cylinder casing, improves system
The cleaning inside sealed cylinder block is improved while the sealing performance of dynamic cylinder；It is set between intermediate sleeve 21 and piston sleeve 11
Guiding lubrication ring 25 is set, makes to brake the raising of the cylinder piston operational efficiency, while reducing maintenance cost.
