It is equipped with plane bearing, clutch disc is pressed on plane bearing, end cap is set with outside clutch disc, return bullet is installed in end cap
Spring is provided with interior adjusting sleeve between shaft and clutch disc, unilateral bearing is provided with outside interior adjusting sleeve, is provided with outside unilateral bearing
Adjusting sleeve.
The position that the shaft cooperates with end cap is provided with slot and fixes with end cap, and axis elasticity gear is provided on end cap
Circle.
It is connected through a screw thread between the shaft and screw putter.
The adjusting sleeve controls the rotation of interior adjusting sleeve by unilateral bearing.
The reference seat is fixedly connected with shaft.
The invention patent innovatively changes all constituents of existing product, eliminates torsional spring product, as Fig. 2,3,
4,5 adjustment shaft torsional spring structure is changed to unilateral bearing and is inserted in structure, adjusting sleeve is improved, unilateral bearing is pressed into and is adjusted
In set, bearing assembly is formed, then shaft is pressed into bearing assembly.It is combined with turning collar using torsional spring before change for adjusting sleeve,
After change, unilateral bearing is pressed in adjusting sleeve, interior adjusting sleeve is inserted in unilateral bearing, is formed unilateral bearing component, is played list
Realize that adjusting sleeve drives the one-way movement of shaft by unilateral bearing component to clutch action；
The antioverloading component of adjuster is improved, cancels compressed spring, the end axle construction of shaft is not being influenced
It is changed under the premise of whole height, the mounting plane bearing on one plain washer of end installation, plain washer, on plane bearing
It is pressed internal and external gear clutch piece, the whole end cap of clutch disc housing adjustment forms plane bearing component plane bearing component and mainly exists
Antioverloading function is played in the constant situation of brake clearance, in the case where brake clearance does not need adjusting, pressure arm stirs adjustment
Set, only adjusting sleeve and the plane bearing component of adjustment cover internal mutually skid, and guarantee that adjustment shaft is motionless, to avoid whole
A adjuster work, prevents the toning of brake process gap.
Two parallel planes will be milled out by cylinder at the cooperation of shaft and adjustment end cap, adjustment end cap is just matched with shaft
It closes, can effectively avoid adjustment end cap radial motion, fixed with circlip for shaft by end cap is adjusted at adjustment end cap, avoid adjusting
Whole end cap is axially moved.

Specific embodiment
The invention patent innovatively changes all constituents of existing product, eliminates torsional spring product, as Fig. 2,3,
4,5 adjustment shaft torsional spring structure is changed to unilateral bearing and is inserted in structure, adjusting sleeve is improved, unilateral bearing is pressed into and is adjusted
In set, bearing assembly is formed, then shaft is pressed into bearing assembly.It is combined with turning collar using torsional spring before change for adjusting sleeve,
After change, unilateral bearing is pressed in adjusting sleeve, interior adjusting sleeve is inserted in unilateral bearing, is formed unilateral bearing component, is played list
Realize that adjusting sleeve drives the one-way movement of shaft by unilateral bearing component to clutch action；
The antioverloading component of adjuster is improved, cancels compressed spring, the end axle construction of shaft is not being influenced
It is changed under the premise of whole height, the mounting plane bearing on one plain washer of end installation, plain washer, on plane bearing
It is pressed internal and external gear clutch piece, the whole end cap of clutch disc housing adjustment forms plane bearing component plane bearing component and mainly exists
Antioverloading function is played in the constant situation of brake clearance, in the case where brake clearance does not need adjusting, pressure arm stirs adjustment
Set, only adjusting sleeve and the plane bearing component of adjustment cover internal mutually skid, and guarantee that adjustment shaft is motionless, to avoid whole
A adjuster work, prevents the toning of brake process gap.
Two parallel planes will be milled out by cylinder at the cooperation of shaft and adjustment end cap, adjustment end cap is just matched with shaft
It closes, can effectively avoid adjustment end cap radial motion, fixed with circlip for shaft by end cap is adjusted at adjustment end cap, avoid adjusting
Whole end cap is axially moved.
Single push rod adjuster assembly of clutch bearing assembly combination clutch plane bearing modular construction by screw putter,
Adjust the composition such as shaft, support base, adjusting sleeve, unilateral bearing component, interior adjusting sleeve, return spring, clutch disc, end cap.
Product realizes the one-directional rotation of adjustment shaft using unilateral bearing component, is realized using clutch plane bearing component
The overload prevention function (skidding function) of adjustment mechanism.
When brake pressure arm pushes, adjusting sleeve rotation is driven, adjusting sleeve rotation can make interior adjusting sleeve in the work of unilateral bearing
With lower rotation, when interior adjusting sleeve rotates, under the active force of clutch disc and end cap, make to adjust shaft rotation, and then make screw thread
Push rod is opposite outward to be screwed out, and is pushed brake block to travel forward, is compensated the brake clearance between brake block and brake disc, reach braking
Effect.
Brake pressure arm continues to push, and adjusting sleeve and the rotation of interior adjusting sleeve limit screw thread and push away since brake clearance is eliminated
The rotation of bar and shaft causes the plane clutch component in end cap to overcome the frictional force of return spring offer and rotate (skidding),
To reach the function that the entire adjuster inner body of self-protection is not damaged.When pressure arm return, adjusting sleeve is driven to turn
It is dynamic, but interior adjusting sleeve will not rotate under the effect of unidirectional shaft with the rotation of adjusting sleeve, pressure arm returns to initial position.
Torsional spring and compressed spring are eliminated in the invention, single direction rotation is realized using clutch bearing and plane bearing and is beaten
Sliding function, greatly improves the reaction sensitivity of product, improves life of product, avoid many due to caused by spring failure
Potential risk.
Entire modular construction advantages of simple, is readily produced and assembles, and is especially more convenient for repairing and replace, is mounted on caliper
On, it just exactly matches, meets brake gap adjustment function, overall performance and service life are greatly promoted, quality
It is more stable.
Single push rod adjuster assembly of clutch bearing assembly combination plane bearing modular construction of the invention turns round adjustment
Spring is cancelled, and substitutes torsional spring using unilateral bearing component, compressed spring is cancelled, and substitutes compression bullet with clutch plane bearing component
Spring completely eliminates spring product since the performance degradation etc. after the performance deficiency and Reusability of spring steel wire itself is asked
Topic, greatly improves the sensitivity of tune gap and service life of adjustment mechanism, improved product does not influence the unidirectional of product not only
Twisting force, and effectively improve antioverloading function, product processing are extremely easy and for ease of maintenaince.
The invention patent is the adjustment mechanism of the automatic compensation brake clearance applied to disk brake, and product is using unidirectional
Bearing assembly realizes the one-directional rotation of adjustment shaft, and the overload prevention function of adjustment mechanism is realized using clutch plane bearing component
Energy (skidding function).Applied to safety, stability and the service life in brake, greatly promoting brake.
