Specific implementation mode
As shown in Fig. 1,2,3,4,5, a kind of two-sided disc brake of hinge type pull rod, including tie rod arm 6, pull rod 7, big caliper 9, the right side
Side brake block 20, left side brake block 22 and small caliper 26, it is characterised in that：The tie rod arm 6 passes through several flat base screws 2 and drawing
Bar 7 is connected, and tie rod arm 6 is equipped with crimping screw 4, and crimping screw 4 is equipped with tension disc 5, and tie rod arm 6 is equipped with cored screw
1, the tie rod arm 6 is connected by cored screw 1 with upper right mandril 12, and upper right mandril 12 is positioned in big caliper 9, upper right top
Bar 12 is equipped with flat shim 10 and plane bearing 11, and steel ball 13, bottom right mandril are equipped between upper right mandril 12 and bottom right mandril 14
14 are equipped with big caliper spring 15, and big caliper spring 15 has and tight screw 16, and tight screw 16 has adjusting screw 17,
Adjusting screw 17 has strong magnet 19, and strong magnet 19 has right hand side brake piece 20, right hand side brake piece 20 and left side brake block
Brake flat spring 21 is equipped between 22, brake flat spring 21 is fixed on by small guide post 18 on big caliper 9, under left side brake block 22
Equipped with loose flange 24, special screw 23 is equipped among loose flange 24, loose flange 24 has left mandril 25, left mandril 25
Steel ball 13 is equipped between small caliper 26, big caliper 9 and small caliper 26 are linked together by connecting screw 27, loose flange 24
It is connected to a fixed on small caliper 26 by special screw 23 and six slot screws 8, the special screw 23 is M3x10 screws, institute
Bottom right mandril 14 is stated to position with the groove 29 on big caliper 9 by the boss 28 on bottom right mandril 14 with big caliper 9, it is described small
The trajectory on trajectory and bottom right mandril 14 on caliper 26 is left-handed, and the small caliper 26 and left mandril lid set for integral type
Meter.
Operation principle is：Rotate clockwise pull rod 7, drive right side upper ejector pin 12 in company with movement, bottom right mandril 14 with
Big caliper 9 is positioned by the boss 28 on bottom right mandril 14 with the groove 29 on big caliper 9, cannot be freely rotated, Zhi Nengzuo
Move up and down, due to its mating trajectory be it is left-handed, in 12 rotation process of upper right mandril, by steel ball 13 push bottom right mandril to
Lower movement pushes the side brake block 20 to apply pressure to brake disc eventually by adjusting screw 17.
Pull rod is rotated clockwise, drives upper right mandril 12 to rotate simultaneously, also drives left mandril 25 to rotate in same direction, left mandril
Lid uses unitary design with small caliper 26, and trajectory directly designs on small caliper 26, and is similarly left-handed, therefore left mandril 25
When rotation, which pushes left mandril 13 to move upwards, and pushes the side to stop from the other side eventually by loose flange 24
Vehicle piece 22 applies pressure to brake disc, completes bi-directional braking pattern.
Releasing lever 7, big caliper spring 15 drives upper right mandril 12 and bottom right mandril 14 to reset, simultaneously because pull rod 7
Body design is spring steel, after releasing lever 7, is discharged and resets by the pull rod 7 compressed, drive left mandril 25 to reset, the binder
Using two-sided adjustable design, right side passes through cored screw 1 to adjust 17 position of adjusting screw adjustment right side using allen wrench
20 gap of brake block, left side adjust six slot screws 8 adjustment loose flange, 24 position, so as to adjust left side 22 gaps of brake.
It is designed using upper lower push rod side：The design scheme is drawn since side uses upper and lower push rod structure during use
The both sides that 7 decrement of bar only originally used be mandril, mandril lid structure half, make big row in original design structure
When journey is braked, pull rod 7 easily drives mandril to tilt, and the defect for causing brake block not parallel is corrected substantially；Composite braces design：
Tie rod arm 6 is fixed on by two flat base screws 2 on pull rod 7, can expand bracing wire installation site by the design, including certainly
By 4 fixed angle of change crimping screw, avoids interfering with vehicle frame, influence installation operation；Small caliper, left mandril lid integral type are set
Meter：Directly left mandril lid ballistic design on small caliper 26, by the way that this layout optimises component Configurations, reduce installation step
Suddenly, and the control of trajectory angle is more accurate, avoids original left mandril lid and the processing of 26 integrated positioning angle of small caliper misses
Difference, right side are limited by space, and small brake block, left side can only be used to use big brake block, increase brake block service life.
Those skilled in the art of the present invention can do described specific embodiment various
Modify or supplement or adopt similar mode substitutes, but without departing from the spirit of the present application or surmounts appended right and want
Seek range defined in book.
