Operation principle：Brake is at initial normal brake application gap, and during braking, brake chamber acts on pressure arm, makes convex
The pressure arm of wheel construction drives support base compression retracteding position spring, and whole adjustment mechanism assembly is relatively fixed reference plane and starts down to transport
Move to eliminate normal brake application gap.Brake push pedal promotion brake block and active force is on brake disc, realize normal brake application.Now press
The downside for stirring pin from adjusting sleeve clearance groove of the arm of force turns to upper side, when the upside upper thread for stirring pin and adjusting sleeve clearance groove
During contact, it is zero that just normal brake application gap, which is eliminated, and for adjustment mechanism, pressure arm continues to push, due to now brake cabin
Gap is zero, so adjusting bolt can not be rotated, and then be acted in homophony rotating shaft, makes homophony rotating shaft keep not rotating, unidirectional
Turning collar is still rotated with adjusting sleeve under the single effect of bearing, relative with the fixed cover equipped with dish-shaped gasket assembly to skid, to disappear
Except the stress produced by rotation, and make whole mechanism parts injury-free.
During Excessive brake gap：After frequent braking, brake disc and brake block can produce abrasion, therefore can produce excess
Brake clearance.When excessive brake clearance is produced, pressure arm, which is pushed and driven, stirs pin rotation, and pressure arm stirs pin can be by adjusting
The upper side of a whole set of clearance groove stirs adjusting sleeve rotation, now, due to using unilateral bearing knot in turning collar between adjusting sleeve
Structure, therefore the rotation of adjusting sleeve, drive homophony rotating shaft to be rotated simultaneously under unilateral bearing effect, the rotation of homophony rotating shaft makes rotating shaft
Interior adjusting bolt is screwed out out against, compensates brake clearance, at the same time, and homophony rotating shaft drives regulation pinion rotation, regulation
The rotation of gear is engaged using gear to be made to rotate from the regulation gear synchronous for turning axle, is driven from turning axle synchronous axial system, so that
Ensure that the adjusting bolt from axle is turned also outwards is screwed out, synchroballistic brake clearance.Thus clearance self-regulating function is produced, was made
Obtain gap to be gradually reduced, eliminate excessive gaps.
In real work, the clearance self-regulating distance of adjustment mechanism is far longer than the wear extent of brake disc and brake block, institute
So that when without departing from normal brake application gap width, brake block end face is brought into close contact with brake disc during braking, now, adjustment mechanism assembly
Bullet in reinforcement and pressed part becomes state, and when pressure arm continues to push, pressure arm stirs pin and drives adjusting sleeve to be rotated further,
Until brake disc is embraced completely, now because brake clearance is zero, homophony rotating shaft, from turning axle and adjusting sleeve, pressure arm, branch
There can be very big braking reaction force between the parts such as support seat, i.e. brake disc react on adjusting bolt and then act on tune
On the parts such as the whole series, now adjusting bolt is remained stationary as, and then remains stationary as main modulation rotating shaft, but adjusting sleeve is still with pressure
The arm of force is rotated, and the unilateral bearing in adjusting sleeve can drive turning collar to rotate, and turning collar is produced with the fixed cover component in homophony rotating shaft
Raw relative skidding（The breakaway torque of dish-shaped gasket assembly is less than the nominal torque of unilateral bearing）, so that adjustment mechanism device is only
Braking is participated in, gap adjustment is not involved in, avoids, in brake clearance interference, adjustment mechanism zero being destroyed because of reaction force completely
Part, lifts adjustment mechanism service life.
When braking return, while pressure arm rises, support base return in the presence of return spring drives braking push pedal
Return, so as to return to initial position.Adjustment mechanism assembly is at normal brake application gap, pressure arm return, pressure arm stir pin from
The upper side of adjusting sleeve clearance groove starts downward flank movement, and is contacted with the downside of adjusting sleeve clearance groove, finally returns to
It is in situ；After gap adjustment is realized, during adjustment mechanism return, with the return of pressure arm, adjusting sleeve is driven to rotate counterclockwise, this
When, in the presence of unilateral bearing, adjusting sleeve and turning collar are in idling conditions, the elasticity pressure of pressed part with respect to other parts
Power successive elimination simultaneously restores to the original state, and all parts all revert to original state.
The adjuster is by homophony rotating assembly, from turning shaft assembly, adjusting sleeve component, support base, pressure arm component, bottom
Constituted with push pedal etc..Principal and subordinate turns shaft assembly and regulation gear is arranged on support base, and regulation gear is installed in the middle of support base, is protected
Demonstrate,prove and turn the gear intermeshing on shaft assembly with principal and subordinate and rotate freely；Adjusting sleeve component is arranged in homophony rotating shaft, in branch
Support to install successively below seat and semicircle needle bearing, pressure arm, support are installed successively in the middle of bottom component and braking push pedal, support base
Cylinder, pressure arm stirs pin in adjusting sleeve allocating slot, is finally coupled with pressure arm fixed mount with bottom, it is ensured that overall assembly
It is firm.
