The outer cylinder of hand adjustment nut 36 is provided with convex tendon 36b, in order to rotate hand adjustment nut 36.
The operation principle of the present invention is as follows：
Brake lining and braking dish gap nominal situation：During braking, pressure air enters integral films through the passage 22b of cylinder body 22
9 right side, because of the sealing function of integral films 9, pressure differential is formed in its both sides, promotes piston composition 10 to move to left, compression is alleviated
Spring 8 simultaneously drives the unidirectional automatic regulating apparatus 12 in brake lining gap, brake lining gap manual adjusting device 3 to be moved to the left together, mobile
One standard clearance A, this value is the distance that guide blot 5 moves on to right edge from the adjustment slotted hole 24a left sides of buting iron 24, now
Driven through disc brake clamp (not shown), brake lining just reclines on the disc brake rotor, that is, completes braking action.Lock
The brake force of piece is delivered on piston 19 by screw rod 30, guiding nut 29, guiding buting iron 33, piston rod 20, right with piston 19
The pressure air interaction of side, forms stable on-position.During alleviation, pressure air through the passage 22b of cylinder body 22 by arranging
Go out, piston composition 10 returns to the bottom of cylinder body 22, drive brake lining gap unidirectionally to adjust automatically under the extension effect of release spring 8
Engagement positions 12, brake lining gap manual adjusting device 3 move right together, and mobile distance is exactly standard clearance A values, alleviate knot
Beam.
Brake lining and the braking excessive operating mode of dish gap：During braking, pressure air enters integral films through the passage 22b of cylinder body 22
9 right side, because of the sealing function of integral films 9, pressure differential is formed in its both sides, promotes piston composition 10 to move to left, compression is alleviated
Spring 8 simultaneously drives the unidirectional automatic regulating apparatus 12 in brake lining gap, brake lining gap manual adjusting device 3 to be moved to the left the f's of A ten together
Distance, f values are because brake lining is more than increased displacement after normal value with braking dish gap after brake lining and brake disc abrasion, now
Brake lining in disc brake just reclines on the disc brake rotor, that is, completes braking action.During this, the quilt of buting iron 24 is adjusted
Guide blot 5 is blocked on cylinder cap 18, only moves standard clearance A values, it is impossible to continue to move to, then compress compression spring
The conical clutch of 26, the adjustment conical surface 24b of the buting iron 24 and conical surface 31a of adjusting nut 31 formation is disengaged, in the effect of compression spring
Under, drive adjusting nut 31 to be rotated on screw rod 30 and move right, the brake disc until brake lining reclines, now, adjustment buting iron 24 are bored
Face 24b is engaged again with the conical surface 31a of adjusting nut 31, the adjusting nut 31 and formation gap f of spacing ring 32, and screw rod 30 is relative to be adjusted
Nut 31 extends f to the left.The brake force of brake lining is delivered to work by screw rod 30, guiding nut 29, guiding buting iron 33, piston rod 20
On plug 19, interacted with the pressure air on the right side of piston 19, form stable on-position.Being divided into two stages during alleviation enters
OK, the first stage, pressure air through the passage 22b of cylinder body 22 by being discharged, and piston composition 10 is acted in the extension of release spring 8
Under, return to release position, drive the unidirectional automatic regulating apparatus 12 in brake lining gap, brake lining gap manual adjusting device 3 together to
Move right, moving distance value is standard clearance A.Second stage, pressure air continues to discharge, and piston composition 10 is in release spring 8
Extension effect under continue to move to the right.Now, adjustment buting iron 24 is installed in guide blot 5 on cylinder cap 18 and blocked, no longer to
Move right, because adjusting work of the conical clutch in compression spring 26 of the conical surface 24b of the buting iron 24 and conical surface 31a of adjusting nut 31 formation
The position of engagement is in lower, adjusting nut 31 also no longer moves right with screw rod 30.And because stop screw 25 with piston rod 20 to
It is shifted to the right to, drives the guiding compression of buting iron 33 compression spring 26 to continue to move on to the right, the guiding conical surface 33b of buting iron 33 and guiding nut 29
The conical surface 29a formation conical clutch disengage, in the presence of compression spring 26, promote guiding nut 29 on screw rod 30 to the right
It is in rotary moving, form the states that screw rod 30 is motionless and guiding nut 29 moves right together in company with piston composition 10.When it is mobile away from
During from f, piston composition 10 returns to the bottom of cylinder body 22, and the guiding conical surface 33b of buting iron 33 is engaged again with the conical surface 29a of guiding nut 29,
The adjusting nut 31 and gap f of spacing ring 32 is eliminated, and alleviation terminates.By the alleviation process in the two stages, brake lining gap is unidirectional
Automatic regulating apparatus 12 makes screw rod 30 stretch out f values to the left with respect to adjusting nut 31, eliminates brake lining and braking through adjust automatically
Plate wheel wears away increased brake clearance, brake lining gap has been returned to standard value again.
Brake lining gap manually adjusts operating mode：When manually adjusting brake lining and braking dish gap, turned with hand or by instrument
Hand adjustment nut 36, because hand adjustment nut 36 is consolidated with screw rod 30 by bolt, now by the trend for driving screw rod 30 to have rotation, due to
Screw head 35 is connected with disc brake clamp and can not rotated, the right-hand member face cone tooth 35c of screw head 35 and the left side of screw rod 30
Active force between cone tooth 30b will make screw rod 30 disengage the cone tooth field of conjugate action in rotation, during the cone tooth field of conjugate action is disengaged
Locking spring 39 will be compressed.When rotating clockwise hand adjustment nut 36, screw rod 30 will be taken to and screw out adjusting nut 31, brake lining to the left
It will be turned down with braking dish gap, when rotating counterclockwise hand adjustment nut 36, screw rod 30 precession adjusting nut 31, lock to the right will be taken to
Piece and braking dish gap will be tuned up.
Hand braking operating mode：When vehicle implements hand braking, car body hand brake device (not shown) forces in hand braking
The pin-and-hole 1a of the one end of lever 1.Bearing pin rotation in the thorny pin-and-hole 17a of Brake Block 17 of hand brake lever 1, group of hand brake lever 1
Fork 1b contacts push away iron 4, then stir and push away iron 4, drive piston rod 20 to be stretched out from inner hole of cylinder cover 18b, so as to drive piston to constitute
10 are moved to the left, and subsequent process and action are seldom repeated with the retarder location of brake lining and braking dish gap nominal situation.
"left", "right" position relationship in above-described embodiment and the installation drawing right position relation one in Figure of description
