Referring to 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
Designed using wedge shape section, its actual movable space is then by the square key groove on cylinder cap pipe 113 and common group of wedge-shaped adjusting block 115
Into.Setting height(from bottom) of the wedge-shaped adjusting block 115 on cylinder cap pipe 113 is can adjust by adjusting adjusting screw 118, that is, have adjusted wedge shape
The height of the lozenges of adjustment block 115, so as to change the movable distance in axial direction of the square key 198 in square key groove i.e. maximum without adjustment
Stroke S1.Principle is adjusted from the gap of checking cylinder, walking stroke S when the actual sky of piston is more than maximum without adjustment stroke S1 with adjusting
The end tooth engagement height N sums of nut 131 are saved, the end tooth mutual with cone tooth sliding sleeve 132 of adjusting nut 131 is kept completely separate, triggered
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 screw 118 adjust wedge-shaped adjusting block 115 height, change between its lozenges and the lozenges of square key 198 axially 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 promotes piston modules compression 199 outside sidesway of release spring
It is dynamic.Guiding resistance mode transfer block is threadably secured with piston tube 122 to be connected, and it is moved laterally with piston modules.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.Now hindered in guiding and adjust inside modules, because resistance adjusts the elastic force of spring 147 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 axle hair
Raw rotation, relative position of the adjustment axis with guiding nut 143 in the axial direction is constant, i.e., guiding nut 143 passes through trapezoidal thread band
Dynamic adjustment axis synchronously moves out together.Because the circumference of square key 198 is spacing, in the presence of spring 133 is adjusted, adjusting nut
131 with bore tooth sliding sleeve 132 end tooth be meshed, adjusting nut 131 can not relative adjustment axle rotate, adjustment axis passes through trapezoidal
Screw thread drives gap adjustment module synchronously to move out together, and square key 198 also moves in square key groove 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 actual sky of dynamic cylinder walks stroke S.It is maximum without adjustment stroke S1+ adjusting nuts more than square key 198 that if actual sky walks stroke S
During 131 end tooth engagement height N, in checking cylinder gas replenishment process, square key 198 is with whole gap adjustment module one at first with piston mould
Block is moved out, and when square key stroke reaches S1, its lozenges contacts with wedge-shaped adjusting block, and it is axially moved by spacing.
After this, adjusting nut 131 continues outside lateral movement, adjusting nut 131 and cone tooth sliding sleeve under the drive of adjustment axis screw mandrel 152
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
Circumferential movement constraint release, intermittent rotation takes place in the presence of spring 133 is adjusted, so that adjustment axis screw mandrel
152 relative adjustment nuts 131 are protruding.After brake cylinder exhaust, in the presence of release spring 199, piston to medial motion,
Gap adjustment module, guiding resistance mode transfer block and regulation axle module integrally will be transported also to medial motion, square key 198 to inner side therewith
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 groove inner side end, gap adjustment module will stop moving axially, in adjusting nut 131 and adjustment axis
In the presence of the screw thread of screw mandrel 152 coordinates, adjustment axis can not also continue to move axially.And piston by drive guide resistance adjust device module after
Continuous to move inward, in the presence of guiding nut 143 and the screw thread of adjustment axis screw mandrel 152 coordinate, guiding nut 143 draws compression
Guided missile spring 144, guiding nut 143 will separate with the end tooth of tapered sleeve 145, rotary spacing of the tapered sleeve 145 to guiding nut 143
Release, in the presence of guide springs 144, intermittent rotation will occur for guiding nut 143, so that guiding nut 143 is relative
Axially opposing displacement occurs for adjustment axis screw mandrel 152, and causes guiding resistance mode transfer block to realize the complete reset to inner side.In checking cylinder
Fill before and after exhaust event, because adjustment axis relative gap adjustment module and guiding resistance mode transfer block are there occurs axially opposing displacement, i.e.,
Also opposing pistons module is protruding so that the length elongation of checking cylinder before and after action, be reacted to brake clamp brake lining end its
Bilateral spacing diminishes, and disc gap reduces, i.e., there occurs slack adjusting action.
If the setting height(from bottom) 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 setting height(from bottom) increase Δ H of monoblock 115, 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 square key 198 and the angle of the lozenges of wedge-shaped adjusting block 115 and horizontal plane.And the brake clamp after adjusting delays
Solution gap then adds Δ Sp=Δ S/i=Δs H/ (tan (a) × i) bilateral distance.Thus, can be not using the present invention
In the case of changing any parts, realize checking cylinder maximum without the adjustable of adjustment stroke.The brake lining of brake clamp can be achieved
Alleviate the adjustable of gap width between brake disc.
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 the lozenges of square key 198 contacts with the lozenges of wedge-shaped adjusting block 115, force direction of the square key 198 to wedge-shaped adjusting block 115
Obliquely, now under the pulling force effect of adjusting screw 118, the accurate limit to wedge-shaped adjusting block 115 to can be achieved along lozenges
Position.
