Shown in Fig. 3 to Figure 12, the present embodiment is compared with checking cylinder of the tradition with gap adjustment function, square key 198
It is designed using wedge shape section, practical movable space is then by 115 common groups of square key slot and wedge-shaped adjusting block on cylinder cap pipe 113
At.Mounting height of the wedge-shaped adjusting block 115 on cylinder cap pipe 113 is adjusted by adjusting adjusting screw 118, that is, has adjusted wedge shape
The height of 115 lozenges of adjustment block, to change the movable distance of axial direction of the square key 198 in square key slot i.e. maximum without adjustment
Stroke S1.Maximum is more than without adjustment stroke S1 and tune it is found that walking stroke S when the practical sky of piston by the gap adjustment principle of checking cylinder
The sum of the end tooth engagement height N of nut 131 is saved, the end tooth mutual with cone tooth sliding sleeve 132 of adjusting nut 131 is kept completely separate, triggers
Slack adjusting action occurs for clearance adjustment mechanism, therefore, after multiple slack adjusting action, the alleviation gap of brake clamp
Sp brake discs should be maintained near S1+N/i with gap of the brake lining under relieved state, wherein i is brake clamp lever ratio.It is logical
Overregulate the height that screw 118 adjusts wedge-shaped adjusting block 115, change between 198 lozenges of its lozenges and square key it is axial away from
From changing S1, you can adjust the alleviation gap of brake clamp.
When being filled with compressed air in cylinder body 111, compressed air pushes piston modules to compress 199 outside sidesway of release spring
It is dynamic.Guiding resistance mode transfer block is threadably secured with piston tube 122 to be connect, and is moved outward with piston modules.It is braking
Before the brake lining of clamp is held tightly with brake disc, checking cylinder both ends can be considered free end, i.e., substantially not by the axial direction system from lever
Dynamic loading.It is hindered at this time in guiding and adjusts inside modules, since resistance adjusts 147 elastic force of spring to be much larger than guide springs 144, in guide springs
Under 144 collective effect, guiding nut 143 is meshed with the end tooth of tapered sleeve 145, and guiding nut 143 can not relative adjustment axis hair
Raw rotation, adjustment axis and the relative position of guiding nut 143 in the axial direction are constant, i.e., guiding nut 143 passes through trapezoidal thread band
Dynamic adjustment axis synchronizes together to be moved out.Due to the circumferential direction limit of square key 198, under the action of adjustment spring 133, adjusting nut
131 with cone tooth sliding sleeve 132 end tooth be meshed, adjusting nut 131 can not relative adjustment axis rotate, adjustment axis passes through trapezoidal
Screw thread drives gap adjustment module to synchronize together and moves out, and square key 198 also moves in square key slot therewith.
When the gap Sp between the brake lining of brake clamp and brake disc is larger, made before brake lining does not clamp with brake disc
It is larger that the practical sky of dynamic cylinder walks stroke S.If it is maximum without adjustment stroke S1+ adjusting nuts more than square key 198 that practical sky walks stroke S
When 131 end tooth engagement height N, in checking cylinder gas replenishment process, square key 198 is with entire gap adjustment module one at first with piston mould
Block moves out, and when square key stroke reaches S1, lozenges is contacted with wedge-shaped adjusting block, and axial movement is limited.
After this, adjusting nut 131 continues to move outward under the drive of adjustment axis lead screw 152, adjusting nut 131 and cone tooth sliding sleeve
132 end tooth face is initially separated, and after continuing to move an end tooth engagement height N, end tooth is kept completely separate, adjusting nut 131
Intermittent rotation takes place under the action of adjustment spring 133 in circumferential movement constraint release, so that adjustment axis lead screw
152 relative adjustment nuts 131 are protruding.After brake cylinder exhaust, under the action of release spring 199, piston moves inwardly,
Gap adjustment module, guiding resistance mode transfer block and adjusting axle module will be moved integrally inwardly therewith, and square key 198 is also transported inwardly
It is dynamic.Due in gas replenishment process, the stroke of piston is more than the stroke of square key 198, therefore, in reseting procedure, when square key 198 by
To after the axial limiting of square key slot inner side end, gap adjustment module will stop moving axially, in adjusting nut 131 and adjustment axis
Under the action of 152 screw-thread fit of lead screw, adjustment axis can not also continue to move axially.And piston by drive guide resistance adjust device module after
Continuous to move inward, under the action of guiding nut 143 and adjustment axis 152 screw-thread fit of lead screw, guiding nut 143 draws compression
Guided missile spring 144, guiding nut 143 will be detached with the end tooth of tapered sleeve 145, rotary spacing of the tapered sleeve 145 to guiding nut 143
It releases, under the action of guide springs 144, intermittent rotation will occur for guiding nut 143, to keep guiding nut 143 opposite
Axially opposing displacement occurs for adjustment axis lead screw 152, and guiding resistance mode transfer block is made to realize complete reset inwardly.In checking cylinder
It fills before and after exhaust event, since axially opposing displacement has occurred in adjustment axis relative gap adjustment module and guiding resistance mode transfer block, i.e.,
Also opposing pistons module is protruding so that the length elongation of the front and back checking cylinder of action, be reacted to brake clamp brake lining end its
Bilateral spacing becomes smaller, and disc gap reduces, that is, slack adjusting action has occurred.
As shown in FIG. 13 to 15, for the ease of understanding the technical solution of the application, principle is adjusted to illustrate resistance below：
When being filled with compressed air in brake cylinder body 111, compressed air pushes piston 121 to compress the beginning of release spring 199
It moves outward.Since piston stroke S is more than the maximum without adjustment 131 end tooth engagement height of stroke S1+ adjusting nuts of square key 198
When N, in the braking state under (brake lining hold tightly brake disc, and lever occur flexible deformation after), adjusting nut 131 with cone tooth sliding sleeve
132 end tooth will be kept completely separate.Since checking cylinder (is much larger than resistance by the axial constraint counter-force effect deformed from lever
Adjust the spring force of spring 147), adjustment axis 152 drives guiding nut 143 to squeeze tapered sleeve 145 inwardly, and spring is adjusted in tapered sleeve compression resistance
147 so that the end face of tapered sleeve 145, which compresses and is bonded resistance, adjusts gasket 146.At this point, the end of adjusting nut 131 and cone tooth sliding sleeve 132
Although tooth is kept completely separate, but since resistance adjusts gasket 146 to be compressed by tapered sleeve 145, can not rotate, eventually lead under the force effect that rubs
It can not still be rotated by the nested adjusting nut 131 of key with it, that is, prevent the gap caused by lever flexible deformation excessive
Adjustment.In the process, guiding nut 143 is engaged with the end tooth of tapered sleeve 145, piston tube 122, gap adjustment module, guiding resistance
Mode transfer block is moved with axle module is adjusted with piston 121 is synchronous outward.Checking cylinder length is L0+S at the end of action.
When compressed air is discharged in brake cylinder body 111, piston 121 starts inwardly under the action of release spring 199
It resets.In the process, adjusting nut 131 is engaged with the end tooth of cone tooth sliding sleeve 132, the end tooth of guiding nut 143 and tapered sleeve 145
Engagement, piston tube 122, gap adjustment module, guiding resistance mode transfer block and adjusting axle module are synchronous completely multiple outward with piston 121
Position.Checking cylinder length reverts to L0 at the end of action.
If the mounting height of wedge-shaped adjusting block 115 is H1, the maximum of square key 198 without adjustment stroke is S1；When wedge shape is adjusted
After the mounting height of monoblock 115 increases Δ H, the maximum of square key 198 will also increase Δ S, and Δ S=Δs H/ therewith without adjustment stroke
Tan (a), wherein a are the angle of square key 198 and wedge-shaped adjusting block 115 lozenges and horizontal plane.And the brake clamp after adjusting is slow
Solution gap then increases the bilateral distance of Δ Sp=Δ S/i=Δs H/ (tan (a) × i).
In addition, square key 118 and the lozenges of wedge-shaped adjusting block 115 should use lozenges fit system shown in the drawings, i.e.,
After 198 lozenges of square key is contacted with 115 lozenges of wedge-shaped adjusting block, force direction of the square key 198 to wedge-shaped adjusting block 115
For along lozenges obliquely, at this time, it can be achieved that accurate limit to wedge-shaped adjusting block 115 under the pulling force effect of adjusting screw 118
Position.
