Wall is simultaneously threadedly coupled with swivel nut 12.
Lock claw return spring 17 is provided with second between body component 4 and self-locking mechanism, lock claw return spring 17 is placed on self-locking
On bar 16, the inwall of one end and the end face of body component 4 in second is inconsistent, the other end with it is inconsistent from lock claw 15.From lock claw 15
It is relatively large in diameter end and is provided with bayonet socket 31, lock claw return spring 17 is connected with bayonet socket 31, as shown in Figure 1 and Figure 4.
The side wall of body component 3 is provided with the first air inlet K1 in first, and the side wall of housing assembly 8 is provided with the second air inlet
K2.First air inlet K1 communicates with service brake cavity B；Second air inlet K2 communicates with parking braking chamber C.
The present invention use principle be：During running car, the first air inlet K1 non-compressed airs are filled with, the second air inlet K2
Holding is filled with compressed air, and parking braking chamber C expands, and piston only 7 is moved to the left, and has promoted connection drive sleeve 10 also to moving to left
It is dynamic, so as to promote release ring 11 to act on from lock claw 15, moved to left from lock claw 15 so that locate between lock claw 15 and self-lock rod 16
In released state, lock claw return spring 17 and piston return spring 13 are all in the state compressed.Push rod disk component is being braked
Body component 3 during device returning place force and push rod return spring 20 shift to first under acting on, and contacted with epithelium 2.
During service brake, the first air inlet K1 is filled with compressed air, the increase of service brake cavity B volumes, the phase left side-turning of epithelium 2
Turn, promote push rod disk component to be integrally moved to the left, the thrust of push rod disk component output realizes service brake in brake.
During parking braking, service brake cavity B is filled with compressed air, the increase of service brake cavity B volumes, the sidesway to the left of epithelium 2
Dynamic, push rod disk component also moves to left under the drive of epithelium 2, and the thrust of output is in brake.Due to push rod 21 and self-lock rod
16 are fixedly connected, so push rod disk component has driven the movement of self-lock rod 16 again, self-lock rod 16 also and then moves to left.Meanwhile parking
Brake chamber C pressure releases, piston component is moved right in the presence of the reset force of piston return spring 13, release ring 26 with from lock claw 15
Separation, also moved right under the reset force effect of lock claw return spring 17 from lock claw 15 so that from the external annulus of lock claw 15 and admittedly
The internal ring wall of lock block 14 is bonded to each other, when being located at from lock claw 15 in fixed closing piece 14, in the state being compacted, from lock claw 15
Annular concave-convex structure on internal ring wall is mutually twisted with the annular concave-convex structure on self-lock rod 16, such self-lock rod just be locked,
The position after moving to left has been maintained at, has avoided the generation of the situation to move right, it is ensured that self-lock rod 16 is in the position of service brake
Realize parking braking.
When releasing parking braking, it is only necessary to be filled with compressed air to parking braking chamber C, parking braking from the second air inlet K2
Chamber C expands, and piston only 7 is moved to the left, promotes release ring 26 to act on from lock claw 15, moved to left from lock claw 15 so that from lock claw
15 are not bonded completely in the presence of thrust with fixed closing piece 14, in this case, from the annular concave-convex knot of the internal ring wall of lock claw 15
The annular concave-convex structure of structure 30 and self-lock rod 16 is not fully engaged against, the thrust release between lock claw 15 and self-lock rod 16, from
Locking bar 16 is in the state that can move freely, i.e. released state.Under special circumstances, in the case of if desired for maintenance, general meeting
Release ring 26 is promoted indirectly by turning release set 11, promotes release ring 26 to act on from lock claw 15 so as to exist from lock claw 15
It is not bonded completely with fixed closing piece 14 in the presence of thrust, so as to reach the state of unblock.
