When adjustment nut outside inclined-plane contact adjustment nut overlaps inboard inclined-plane, the rotation of restriction adjustment nut, when adjustment nut inclined-plane contact power-transfer clutch helical teeth, the rotation of restriction adjustment nut.
The helical teeth engagement that make respectively screw rod and adaptor union cooperation place, screw rod and adaptor union are formed as a whole when normal brake application is alleviated, can only be graphic left and right directions crank motion (can not rotate) because of adaptor union is connected with screw rod, when replacing wears away excessive brake lining, only need clockwise rotate the recovery nut, screw rod rotation rollback, adaptor union translation rollback (this moment screw rod and the rotational slide of adaptor union helical teeth) can make screw rod, retractile connector to virgin state like this, need not dismantle any other part.Locating piece can only slide in the sliding tray of piston sleeve, thereby the guiding nut cover can only slide, can not pass on moving, restricted guidance nut rotation when guiding nut overlaps inclined-plane, the inboard inclined-plane contact guidance nut outside.
The common elements brake cylinder is one of Multiple disc brake vitals, has avoided the wearing and tearing of tread brake device to wheel, the requirement of speed-adaptive 120km/h express locomotive braking technology; It is little, in light weight that the common elements brake cylinder has a volume, compact conformation; The driving efficiency height; And have the effect of individual event adjust the clearance, a dependable performance; Braking ratio is easy to adjust, and the brake unit power output is big.
Common elements brake cylinder principle of work
1, the brake action when brake lining and brake disc normal clearance
Enter into the piston head left side at pressure air, promoting piston forms and shows as Fig. 1 and to be moved to the left, piston is formed the drive power-transfer clutch and the adjustment nut cover is moved to the left, gap between elimination of adjustment nut cover and adjustment nut, the promotion adjustment nut is moved to the left, and adjustment nut drives screw rod adaptor union composition and stretches out, and drives the braking clamp, brake lining is pressed on the friction anchor ring of brake disc, produces brake action.
Restoring spring, guide spring are further compressed at this moment, adjust the spring elongation; Guide spring makes the guiding nut cover compress guiding nut, is formed by the screw rod adaptor union to promote to be moved to the left together; Guiding nut and adjustment nut are adjacent to, adjustment nut and clutches engaged, and the guiding nut cover does not contact transfers the crack retaining, and back-up ring is the engagement shaft bearing not.The adjust the clearance effect does not take place in this process.Initial assembly clearance between back-up ring and the bearing seat claims standard clearance, also claims A value, as long as the stroke that the screw rod adaptor union is formed is not more than the A value, the adjust the clearance effect does not take place unit brake cylinder.
2, the mitigation when brake lining and brake disc normal clearance
When the pressure air on piston head right side was discharged, brake cylinder was alleviated.
Restoring spring promotes the piston composition and moves to right, and piston is formed the drive power-transfer clutch and the adjustment nut cover moves to right, and power-transfer clutch promotes adjustment nut, and adjustment nut drives screw rod adaptor union composition and moves right, and drives the clamp composition and resets, and brake lining leaves brake disk surface.
This moment, restoring spring and guide spring restored, and the guiding nut cover compresses guiding nut, were formed to drive by the screw rod adaptor union to be moved to the left together; Guiding nut and adjustment nut compress, adjustment nut and clutches engaged; Adjustment nut and adjustment nut cover recover the gap.The adjust the clearance effect does not take place in this process.
3, the excessive adjust the clearance brake action of brake lining and brake disc
Along with the wearing and tearing of brake lining, the gap between brake disc and the brake lining increases gradually, and the stroke that this moment, the screw rod adaptor union was formed must could drive the braking clamp greater than the A value, and brake lining is pressed on the friction anchor ring of brake disc, produces brake action.
At first, when the stroke that the screw rod adaptor union is formed was not more than the A value, the brake action when braking procedure and brake lining and brake disc normal clearance was identical.When needs screw rod adaptor union is formed continuation motion H (being meant worn-down gap between brake lining and the brake disc) stroke, brake lining is pressed on the friction anchor ring of brake disc, piston is formed the drive power-transfer clutch and the adjustment nut cover is moved to the left, eliminate the gap between adjustment nut cover and the adjustment nut, drive screw rod adaptor union composition and move to left, the screw rod adaptor union forms the drive guiding nut and guide spring promotes the guiding nut cover together to left movement.
When back-up ring touches bearing seat (finishing stroke A) and continues stroke H, adjust spring and be compressed H again.
Guide spring is derived and is transferred the crack to block to nut sleeve, and guiding nut continues motion, forms the gap between guiding nut cover and the guiding nut.Guiding nut is a non-self-locking nut, so when the screw rod adaptor union was formed shift motion H, guiding nut only rotated and do not follow action.Like this, the screw rod adaptor union is formed traveled distance A+H, drives the braking clamp, and brake lining is pressed on the friction anchor ring of brake disc, produces brake action.
4, the alleviation after the excessive gap braking of brake lining and brake disc
When the pressure air on piston head right side was discharged, brake cylinder was alleviated.
At first, clamp is formed the antagonistic force sheathed screw adaptor union composition of distortion.Restoring spring promotes the piston composition and moves to right.Piston is formed the drive power-transfer clutch and the adjustment nut cover moves to right, and power-transfer clutch promotes adjustment nut, drives the clamp composition and resets, and at this moment, brake lining is in and just leaves the brake disk surface critical conditions.
Restoring spring continues to promote the piston composition and moves to right.The adjustment nut cover promotes adjustment nut and throw-out-of clutch by adjusting spring.Again compressed the H value owing to adjust spring by back-up ring and bearing seat, adjustment nut rotates, and up to adjusting spring by back-up ring and bearing seat amount of compression H elimination again, screw rod adaptor union composition does not move right.This process piston set becomes stroke H, and screw rod adaptor union composition does not move right, and it is 0 that the screw rod adaptor union is formed stroke.At this moment, bearing block transfers the crack to block, and back-up ring and bearing seat are in the critical conditions of separating, and the mitigation position of each component locations during with brake lining and brake disc normal clearance is identical.
Restoring spring continues to promote the piston composition and moves to right, and the mitigation when action and brake lining and brake disc normal clearance is identical.
5, recover the original position of brake cylinder behind the replacing abrasion brake lining
When changing the excessive brake lining of abrasion, only need clockwise rotate the recovery nut, the screw rod adaptor union is formed the rotation rollback, adaptor union translation rollback (screw rod and adaptor union cooperation place helical teeth active flank slided and rotated this moment), can make the screw rod adaptor union form the virgin state that expires of withdrawing like this, need not dismantle any other part.
