When the gap between brake disc and brake lining is in normal range (NR)（3-6mm）, when implementing braking maneuver, compressed air
Enter cylinder body 10 from cylinder body 10-2 air inlet 10-2-1, promote piston 12 and drive piston tube 11, piston lid 4, tapered sleeve
5-4 is travelled forward, and release spring 8 is compressed, and drives adjustment axis 2 to protract by the guiding nut 5-1 engaged with tapered sleeve 5-4, resistance is adjusted
Component 6 and adjusting nut component 7 travel forward with adjustment axis 2, so as to promote lever to implement braking maneuver.When implementation is alleviated
When, in the presence of release spring 8, compressed air discharge, piston component resets backward, is driven and adjusted by guiding nut component 5
Nodal axisn, which is retreated, to be resetted, and resistance adjusts component 6 and section nut assembly 7 to be resetted with piston component, so as to drive lever to implement alleviation action.
Entirely during " braking-alleviation ", relative position of the adjusting nut component 7 on adjustment axis axial direction is constant, that is, before and after acting, cylinder
The screw thread pin-and-hole 1-1 of body screw thread pin-and-hole 10-4 and yoke spacing does not change, therefore the gap between brake disc and brake lining is not
Adjust.
When the gap between brake disc and brake lining exceeds normal range (NR)（>6mm）, when implementing braking maneuver, by piston
Component drives adjustment axis 2 to protract by guiding nut 5-1, when square key 7-5 touches the guide groove 10-3 anterior end surfaces of cylinder cap, by
Excessive in brake disc and brake lining gap, piston component drives adjustment axis to move forward by guiding nut 5-1, and now
The movement of square key suffers restraints, and the cone tooth sliding sleeve 7-4 in adjusting nut component 7 can not also continue to move with adjustment axis, but regulation
Nut 7-1 moves forward under the drive of adjustment axis 2, causes to bore the cone tooth and adjusting nut tapering 7- on tooth sliding sleeve 7-4
Cone tooth 7-1s on 1b is disengaged, that is, is relieved constraint of the cone tooth sliding sleeve 7-4 flank of tooth to adjusting nut 7-1 rotary freedoms, adjusted
Save in the presence of spring 7-2, adjusting nut 7-1 starts to rotate around adjustment axis 2.Adjustment axis 2 in the presence of guiding nut 5-1,
Move forward, realize braking, now, the relative adjustment nut 7-1 of adjustment axis 2 is forward extended out.When implementing to alleviate, alleviating
In the presence of spring 8, compressed air discharge, piston component drives adjustment axis to move backward.Adjusting nut 7-1 is in regulation spring 7-
Under 2 effects, the cone tooth 7-1s on the 7-1b of its tapering is still engaged with the cone tooth on cone tooth sliding sleeve 7-4, it is impossible to rotated, therefore
Resetted with adjustment axis 2 to rear side, until square key 7-5 is contacted with the back end surface of the guide groove 10-3 on cylinder cap 10-1, due to
Stretched out in deboost phase adjustment axis relative adjustment nut, now piston component does not reset completely, due to the work of release spring 8
With piston component still needs to continue to reset, but can not be relatively rotated between adjusting nut 7-1 and adjustment axis 2, then adjustment axis 2 can not
Further backward side move, now, guide springs 5-2 is compressed, tapered sleeve 5-4 by piston lid 4 promotion, tapered sleeve 5-4's
Inner cone tooth 5-4s and guiding nut 5-1 cone tooth is disengaged, so as to relieve the tapered sleeve flank of tooth to guiding nut 5-1 rotary freedoms
Constraint, in the presence of guide springs 5-2, guiding nut 5-1 starts to rotate around adjustment axis, and piston component drives guiding nut 5-
1, relative to adjustment axis further side movement backward, finally realizes the complete reset of piston.During whole " braking-alleviation ",
Relative position of the adjusting nut component 7 on adjustment axis axial direction changes, the screw thread pin-and-hole of cylinder body screw thread pin-and-hole 10-4 and yoke
1-1 spacing changes, therefore the gap shrinks between brake disc and brake lining.After multiple " braking-alleviation ", final braking
Gap between disk and brake lining will stabilise in normal range (NR).
Because brake force is larger in braking procedure, lever can be made to produce certain elastic deformation, lever deformation makes adjustment axis
Stretch out quantitative change big, it may occur that the gap adjustment in braking procedure, so may result in disc gap and diminish.
When producing lever deformation, because adjustment axis is promoted forward, square key 7-5 touches the guide groove 10-3 front side ends of cylinder cap
Cone tooth on face, cone tooth sliding sleeve 7-4 is disengaged with the cone tooth 7-1s on the 7-1b of adjusting nut tapering, during this, the meeting of adjustment axis 2
The resistance produced is deformed by lever, this resistance promotes tapered sleeve, tapered sleeve 5-4 axles in piston lid 4 by guiding nut 5-1
Hindered to mobile compression and adjust spring 6-3, tapered sleeve 5-4 extension outer tube 5-4a, which will hinder, adjusts pad 6-2 to be close on resistance tune guide bracket 6-1,
Resistance is set to adjust pad 6-2 not rotate, because resistance adjusts pad 6-2 to be connected with adjusting nut 7-1 types face, so adjusting nut 7-1 is de-
It can not still be rotated when opening, so that gap adjustment when preventing the lever to deform.When resistance disappears, spring 6-3 is adjusted to help by resistance multiple
Position.
Unit brake cylinder regular maintenance in use, sometimes for the spacing between artificial adjustment brake lining and brake disc,
Such as change brake lining.When needing to carry out hand-reset, spanner spinning reduction nut 14, reduction nut compressed waveform elastomeric pad are used
13, jack-up is arranged on the end tooth set 2-s in adjustment axis, disengages the end-tooth that end tooth covers the end-tooth on 2-s and yoke 1, releases
Constraint to the rotational freedom of adjustment axis 2, so as to drive adjustment axis to retract backward, realizes hand-reset function.
