When the gap between brake disc and brake lining is in normal range (NR)（3-6mm）, when implementing braking maneuver, compressed air Enter brake cylinder casing A8 from brake cylinder casing A8 air inlet, promote piston A12 and drive piston tube A11, piston lid A4, tapered sleeve A5-4 is travelled forward, and release of brake spring A10 is compressed, and adjustment axis A2 is driven by the guiding nut A5-1 engaged with tapered sleeve A5-4 Extension, resistance adjusts component A6 and adjusting nut component A7 to be travelled forward with adjustment axis A2, so that it is dynamic to promote lever to implement braking Make.When implementing to alleviate, in the presence of release of brake spring A10, compressed air discharge, piston component resets, passed through backward Guiding nut component A5 drives adjustment axis A2 to retreat reset, and resistance adjusts component A6 and section nut assembly A7 to be resetted with piston component, from And drive lever to implement alleviation action.During whole " braking-alleviation ", adjusting nut component A7 is on adjustment axis A2 axial directions Relative position it is constant, that is, act before and after, the screw thread pin-and-hole A13-1 of brake cylinder casing screw thread pin-and-hole A8-1 and yoke spacing does not occur Change, therefore the gap between brake disc and brake lining is not adjusted.

When the gap between brake disc and brake lining exceeds normal range (NR)（>6mm）, when implementing braking maneuver, by piston Component drives adjustment axis A2 to protract by guiding nut A5-1, and the guide groove A1-1a on central tube A1-1 is touched as square key A7-5 Anterior end surface when, because brake disc and brake lining gap are excessive, piston component drives adjustment axis will be after by guiding nut A5-1 It is continuous to travel forward, and now square key A7-5 movement suffers restraints, the cone tooth sliding sleeve A7-4 in adjusting nut component A7 can not yet Continue to move with adjustment axis A2, but adjusting nut A7-1 moves forward under adjustment axis A2 drive, causes to bore tooth sliding sleeve Cone tooth on A7-4 is disengaged with the cone tooth A7-1s on the A7-1b of adjusting nut tapering, that is, is relieved the cone tooth sliding sleeve A7-4 flank of tooth and exchanged The constraint of nut A7-1 rotary freedoms is saved, in the presence of regulation spring A7-2, adjusting nut A7-1 starts around adjustment axis A2 Rotation.Adjustment axis A2 is moved forward in the presence of guiding nut A5-1, realizes braking, now, and adjustment axis A2 is relative to be adjusted Section nut A7-1 is forward extended out.When implementing to alleviate, in the presence of release of brake spring A10, compressed air discharge, piston group Part drives adjustment axis A2 to move backward.Adjusting nut A7-1 is under regulation spring A7-2 effects, the cone tooth on the A7-1b of its tapering A7-1s is still engaged with the cone tooth on cone tooth sliding sleeve A7-4, it is impossible to rotated, therefore multiple to rear side with adjustment axis A2 Position, until square key A7-5 is contacted with the back end surface of the guide groove A1-1a on central tube A1-1, due in deboost phase adjustment axis A2 Relative adjustment nut A5-1 stretches out, so piston component does not reset completely, in the presence of release of brake spring A10, piston Component still needs to continue to reset, but can not be relatively rotated between adjusting nut A7-1 and adjustment axis A2, then adjustment axis A2 can not enter one Step backward moved by side, and now, guide springs A5-2 is compressed, and tapered sleeve A5-4 is promoted by piston lid A4, tapered sleeve A5-4's Inner cone tooth A5-4s and guiding nut A5-1 cone tooth is disengaged, and guiding nut A5-1 is rotated freely so as to relieve the tapered sleeve flank of tooth The constraint of degree, in the presence of guide springs A5-2, guiding nut A5-1 starts to rotate around adjustment axis, and piston component drives guiding Nut A5-1 relative to adjustment axis, further move backward by side, finally realizes the complete reset of piston.In whole " braking-alleviation " During, relative positions of the adjusting nut component A7 on adjustment axis axial direction changes, cylinder body screw thread pin-and-hole A8-1 and yoke Screw thread pin-and-hole A13-1 spacing changes, therefore the gap shrinks between brake disc and brake lining.Through multiple " braking-alleviation " Afterwards, the gap between final brake disc 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 A2 is promoted forward, square key A7-5 touches the guide groove A1-1a of central tube Cone tooth on anterior end surface, cone tooth sliding sleeve A7-4 is disengaged with the cone tooth A7-1s on the A7-1b of adjusting nut tapering, during this, Adjustment axis A2 can be deformed the resistance produced by lever, and this resistance promotes tapered sleeve by guiding nut A5-1, and tapered sleeve A5-4 exists Spring A6-3 is adjusted in radial movement compresses resistance on piston lid A4, and tapered sleeve A5-4 extension outer tube A5-4a, which will hinder, adjusts pad A6-2 tight It is attached to resistance to adjust on guide bracket A6-1, makes resistance adjust pad A6-2 not rotate, because pad A6-2 and adjusting nut A7-1 types face is adjusted in resistance Connection, so can not still be rotated during adjusting nut A7-1 disengagements, so that gap adjustment when preventing the lever to deform.When resistance disappears Lose, adjust spring A6-3 to help to reset by resistance.
