One end of spring 6 is fixedly connected with the lower end of the clamp pivoted arm 2, the other end and the spring of first return spring 6
Pin shaft 23 is fixedly connected.In this way, the first return spring 6 plays the role of 4 return of EPB drag-line, the spring shaft on caliper body 1
Pin 23 is for installing the first return spring 6.
On the basis of the technical solution described in front, Fig. 1 is please referred to Figure 17, it is further preferred that, the emergency
Pivoted arm 3 is equipped with bending, and the emergency pivoted arm 3 includes integrally formed pivoted arm ontology 28 and drag-line force bearing plate 18, and the bending is set
In the junction of the pivoted arm ontology 28 and the drag-line force bearing plate 18, the pivoted arm ontology 28 and the clamp pivoted arm 2 are fixed
Connection or rotary type are flexibly connected, and the drag-line force bearing plate 18 is connected and fixed with the emergency drag-line 5.In this way, the emergency
3 bending of pivoted arm is provided with the connection for being conducive to emergency parking drag-line 5 and pivoted arm 3 of meeting an urgent need, the emergency pivoted arm 3 and the emergency parking
Drag-line 5 connects and fixes, and convenient disassembly is easily installed.On the basis of the technical solution described in front, it is further preferred that,
The emergency pivoted arm 3 is equipped with drag-line cable-through hole 19, and the biggish one end in 19 aperture of drag-line cable-through hole is located at the pivoted arm sheet
On body 28, the lesser one end in 19 aperture of drag-line cable-through hole is located on the drag-line force bearing plate 18, the emergency parking drag-line 5
End pass through the drag-line cable-through hole 19 connected and fixed with the drag-line force bearing plate 18.Turn in this way, drag-line cable-through hole 19 is located at
Part aperture on arm body 28 is larger, is convenient for enable the end of emergency parking drag-line 5 to pass through drag-line cable-through hole 19
The installation of emergency parking drag-line 5；The part aperture that drag-line cable-through hole 19 is located on drag-line force bearing plate 18 is smaller, is stayed for meeting an urgent need
Vehicle drag-line 5 and emergency pivoted arm 3 connection, enable meet an urgent need parking drag-line 5 end be connected on drag-line force bearing plate 18 without from
Deviate from drag-line cable-through hole 19.
On the basis of the technical solution described in front, Fig. 1 is please referred to Figure 17, it is further preferred that, the clamp
Pivoted arm 2 is fixedly connected with the emergency pivoted arm 3, and the tail portion of the emergency parking drag-line is arranged with nylon jacket, the nylon jacket
Lower part penetrates lesser one end in drag-line cable-through hole aperture on the drag-line force bearing plate, the top of the nylon jacket with it is described
Drag-line force bearing plate offsets, and the nylon jacket is fixed by spring leaf and drag-line force bearing plate, the spring leaf respectively with the nylon
Set and the drag-line force bearing plate connect and fix.In this way, emergency pivoted arm 3 is fixedly connected with clamp pivoted arm 2, this connection type letter
Single, easy to accomplish, the structure for pivoted arm 3 of meeting an urgent need is simple, while can be realized the purpose of emergency parking, when electronics parking brake 27 fails
When, emergency parking drag-line 5 is pulled, emergency parking drag-line 5 drives emergency pivoted arm 3 to rotate, due to clamp pivoted arm 2 and emergency pivoted arm 3
It is fixedly connected, so emergency pivoted arm 3 will drive the rotation of clamp pivoted arm 2, to push piston component in caliper body 1 to braking
The direction of disk 9 is mobile, and caliper body 1 is made to clamp brake disc 9, to achieve the purpose that parking of meeting an urgent need.In addition, in electronics parking brake
(EPB) when 27 normal work, since emergency pivoted arm 3 is fixedly connected with clamp pivoted arm 2, it will drive and answer when clamp pivoted arm 2 rotates
Racing arm 3 rotates, and then pivoted arm 3 of meeting an urgent need drives emergency parking drag-line 5 to move, by being equipped with nylon on emergency parking drag-line 5
Set 7 is stuck in the top of nylon jacket 7 and pivoted arm 3 of meeting an urgent need for preventing to reduce the abrasion to emergency parking drag-line 5, spring leaf 8
Nylon jacket 7 is deviate from.On the basis of the technical solution described in front, it is further preferred that, the clamp pivoted arm 2 is answered with described
Racing arm 3 is fixedly connected by bolt 10 with nut 11.In this way, being threadedly coupled is that the widely used dismountable fixation of one kind connects
It connects, structure is simple, connection is reliable, is convenient to mount and dismount.
On the basis of the technical solution described in front, Fig. 1 is please referred to Figure 17, it is further preferred that, the emergency

The other end of return spring is fixedly connected with the axis pin of the spring 23 on the caliper body 1.In this way, passing through the second return bullet of setting
Spring 22 plays the role of setting spring trunnion 15 on emergency pivoted arm 3 and providing peace as second spring 5 return of parking drag-line of meeting an urgent need
It decorates.On the basis of the technical solution described in front, it is further preferred that the emergency pivoted arm 3 is equipped with the limit stretched out
Pawl 16, the caliper body 1 are equipped with the limited block 17 of protrusion, and the position-limited claw 16 can release formula phase with the limited block 17
It supports.In this way, position-limited claw 16 and spring trunnion 15 is driven to rotate when pivoted arm 3 of meeting an urgent need rotates, the rotation of spring trunnion 15 makes second time
Position spring 22 compresses, and when position-limited claw 16 offsets with limited block 17, so that emergency pivoted arm 3 be made to stop operating, limits second time
The maximum compressibility of position spring 22, that is, the return amount of the second return spring 22 is limited, prevent return amount excessive.
It is above-mentioned that only the specific embodiment in the present invention is illustrated, but it can not be used as protection scope of the present invention, it is all
Be according to the present invention in design spirit made by equivalent change or modification, be deemed to fall protection scope of the present invention.
