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 the air inlet of brake cylinder casing A8, push piston A12 and drives piston tube A11, piston tube lid A4, tapered sleeve A5-4 travels forward, and release of brake spring A10 is compressed, and drives adjustment axis A2 by the guiding nut A5-1 engaged with tapered sleeve A5-4 Extension, resistance adjust component A6 and adjusting nut component A7 to travel forward with adjustment axis A2, so that it is dynamic to push lever to implement braking Make.When implementing to alleviate, under the action of release of brake spring A10, compressed air discharge, piston component resets backward, passes through Guiding nut component A5 drives adjustment axis A2 to retreat reset, and resistance adjusts component A6 and section nut assembly A7 to reset with piston component, from And lever is driven to implement alleviation movement.During entire " braking-alleviation ", adjusting nut component A7 is in adjustment axis A2 axial direction Relative position it is constant, i.e., movement front and back, the spacing of the screw thread pin hole A13-1 of brake cylinder casing screw thread pin hole A8-1 and yoke do not occur Variation, therefore the gap between brake disc and brake lining does 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 A2 extension by guiding nut A5-1, when square key A7-5 touches the guide groove A1-1a on central tube A1-1 Front end face when, since 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 the movement of square key A7-5 at this time 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 the drive of adjustment axis A2, causes to bore tooth sliding sleeve Cone tooth on A7-4 and the cone tooth A7-1s on the A7-1b of adjusting nut tapering are disengaged, that is, are relieved the cone tooth sliding sleeve A7-4 flank of tooth and exchanged The constraint of nut A7-1 rotary freedom is saved, under the action of adjustment spring A7-2, adjusting nut A7-1 starts around adjustment axis A2 Rotation.Adjustment axis A2 moves forward under the action of guiding nut A5-1, realizes braking, adjusts at this point, adjustment axis A2 is opposite Section nut A7-1 is forward extended out.When implementing to alleviate, under the action of release of brake spring A10, compressed air discharge, piston group Part drives adjustment axis A2 to move backward.Cone tooth of the adjusting nut A7-1 under adjustment spring A7-2 effect, on the A7-1b of tapering A7-1s with the cone tooth engagement on cone tooth sliding sleeve A7-4, can not still be 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, under the action of release of brake spring A10, piston Component still needs to continue to reset, but cannots rotate relative to each other between adjusting nut A7-1 and adjustment axis A2, then adjustment axis A2 can not be into one Side is mobile backward for step, at this point, guide springs A5-2 is compressed, promotion of the tapered sleeve A5-4 by piston tube lid A4, tapered sleeve A5-4's The cone tooth of inner cone tooth A5-4s and guiding nut A5-1 disengages, and rotates freely to relieve the tapered sleeve flank of tooth to guiding nut A5-1 The constraint of degree, under the action of guide springs A5-2, guiding nut A5-1 starts to rotate around adjustment axis, and piston component drives guidance Further side is mobile backward relative to adjustment axis by nut A5-1, the final complete reset for realizing piston.In entire " braking-alleviation " In the process, relative position of the adjusting nut component A7 in adjustment axis axial direction changes, cylinder body screw thread pin hole A8-1 and yoke The spacing of screw thread pin hole A13-1 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).
Since brake force is larger in braking process, lever can be made to generate certain flexible deformation, lever deformation makes adjustment axis Overhang becomes larger, it may occur that the gap adjustment in braking process will lead to disc gap in this way and become smaller.
When generating lever deformation, since adjustment axis A2 is pushed forward, square key A7-5 touches the guide groove A1-1a of central tube Front end face, bores the cone tooth on tooth sliding sleeve A7-4 and the cone tooth A7-1s on the A7-1b of adjusting nut tapering is disengaged, during this, Adjustment axis A2 will receive the resistance that lever deformation generates, this resistance pushes tapered sleeve by guiding nut A5-1, and tapered sleeve A5-4 exists Radial movement compresses resistance adjusts spring A6-3, the extension outer tube A5-4a of tapered sleeve A5-4 to adjust gasket A6-2 tight resistance on piston tube lid A4 It is attached to resistance to adjust on guide bracket A6-1, resistance is made to adjust gasket A6-2 that can not rotate, since gasket A6-2 and adjusting nut A7-1 type face are adjusted in resistance Connection, so adjusting nut A7-1 can not still rotate when disengaging, thus gap adjustment when lever being prevented to deform.When resistance disappears It loses, adjusts spring A6-3 help to reset by resistance.
