Seeing shown in Fig. 3 to Fig. 7, compared with the present embodiment and the tradition checking cylinder with gap adjustment function, square key 198 is adopted
Designing with wedge shape section, its actual movable space is then by the square key groove on cylinder cap pipe 113 and the common group of wedge-shaped adjusting block 115
Become.By adjusting the regulation screw 118 scalable wedge-shaped adjusting block 115 setting height(from bottom) on cylinder cap pipe 113, i.e. have adjusted wedge shape
The height of adjustment block 115 lozenges, thus it is the most maximum without adjusting to change the square key 198 axial movable distance in square key groove
Stroke S1.Principle is adjusted, when the actual sky of piston walks stroke S more than maximum without adjusting stroke S1 and tune from the gap of checking cylinder
The end tooth engagement height N sum of joint nut 131, adjusting nut 131 is kept completely separate with the cone mutual end tooth of tooth sliding sleeve 132, triggering
Clearance adjustment mechanism generation slack adjusting action, therefore, after repeatedly slack adjusting action, the alleviation gap of brake clamp
Sp brake disc and brake lining gap under relieved state should be maintained near S1+N/i, and wherein, i is brake clamp lever ratio.Logical
Overregulate screw 118 and adjust the height of wedge-shaped adjusting block 115, change between its lozenges and square key 198 lozenges axial away from
From, i.e. change the alleviation gap of S1, i.e. scalable brake clamp.

152 relative accommodation nuts 131 are protruding.After brake cylinder exhaust, under the effect of release spring 199, piston to medial motion,
Gap adjustment module, guiding resistance mode transfer block and regulation axle module are by entirety therewith to medial motion, and square key 198 is also transported to inner side
Dynamic.Owing to, 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 is subject to
After the axial limiting of square key groove inner side end, stopping is moved axially by gap adjustment module, at adjusting nut 131 and regulation axle
Under the effect of screw mandrel 152 threaded engagement, regulation axle also cannot continue to move axially.And drive is guided resistance to adjust device module to continue by piston
Continuing to medial movement, under the effect of guiding nut 143 and regulation axial filament bar 152 threaded engagement, compression is drawn by guiding nut 143
Guided missile spring 144, guiding nut 143 will separate with the end tooth of tapered sleeve 145, the tapered sleeve 145 rotary spacing to guiding nut 143
Releasing, under the effect of guide springs 144, guiding nut 143 will occur intermittence to rotate, so that guiding nut 143 is relative
There is axially opposing displacement in regulation axial filament bar 152, and makes to guide resistance mode transfer block to realize the reset completely to inner side.At checking cylinder
Before and after filling exhaust event, owing to regulation axle relative gap adjustment module and guiding resistance mode transfer block 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, and 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 is S1 without adjusting stroke；When wedge shape is adjusted
After the setting height(from bottom) of monoblock 115 increases Δ H, the maximum of square key 198 also will increase Δ S, and Δ S=Δ H/ therewith without adjusting stroke
Tan (a), wherein a is the angle of square key 198 and wedge-shaped adjusting block 115 lozenges and horizontal plane.And the brake clamp after adjusting delays
Solve gap and then add the bilateral distance of Δ Sp=Δ S/i=Δ H/ (tan (a) × i).
Additionally, the lozenges of square key 118 and wedge-shaped adjusting block 115 should use lozenges fit system shown in the drawings, i.e.
After square key 198 lozenges contacts with wedge-shaped adjusting block 115 lozenges, the square key 198 force direction to wedge-shaped adjusting block 115
For along lozenges obliquely, now under the pulling force effect of regulation screw 118, the accurate limit to wedge-shaped adjusting block 115 can be realized
