Embodiment: following, the disk type braker of accompanying drawings one embodiment of the invention.
In Fig. 4,5, on non-rotating (toggle) 2 of the vehicle that is set to disk 1 one sides, pair of bolts 3 (referring to Fig. 1) is installed along the axis G of disk 1.Guiding matches to bolt 3 with this respectively with cylindrical piece 4, and this is supporting clamp 5 to guiding slidably with cylindrical piece 4.
Shown in Fig. 1～3, these clamp 5 roughly comprise: hold the oil hydraulic cylinder 6 of piston (not shown), wherein piston with hydraulic operation along the axial direction of disk 1 advance and retreat; Stride across the disk passage 7 that disk 1 extends along disk 1 axial direction from oil hydraulic cylinder 6; Reach disk 1 radially inner side and form a pair of bluff piece 8 of groove part R betwixt from the front end of disk passage 7; And forming a pair of matching hole portion 10 that is communicated with the two ends of oil hydraulic cylinder 6 and connects hole 9 (see figure 4)s of the usefulness cylindrical piece 4 that leads, this clamp 5 obtain by casting.Moreover, on the both sides of the foot of hole 11 of oil hydraulic cylinder 6, form symmetrical a pair of discharge pipe boss 12 and a pair of mounting pipe boss 13, in addition, from the break oil hydraulic circuit connection mouth of the escape cock BV of exhausting air with respect to the connection mouth processing of the break flexible pipe of master hydraulic cylinder bleeder brake device liquid not shown in the figures together.In Fig. 4, show the bluff piece that is positioned at disk 1 gyratory directions inlet side in a pair of bluff piece 8.The bluff piece that is positioned at disk 1 gyratory directions outlet side becomes the back side of the bluff piece 8 of gyratory directions inlet side.And when break moved, the bluff piece of disk 1 gyratory directions outlet side was shown in dotted line, easily outwards distortion.
As shown in Figure 4, disk 1 axially, outer pad 14 is housed between disk 1 and a pair of bluff piece 8, and fills up 15 between disk 1 and oil hydraulic cylinder 6, being equipped with.As shown in Figure 1 and Figure 2, fill up 14 outward, interior pad 15 is made of microscler metallic back veneer 14a, 15a and microscler liner plate 14b, the 15b that engage with this back veneer 14a, 15a respectively.
As shown in Figure 1, the middle body that fills up 14 back veneer 14a outside forms riveted joint protuberance 14c, so form a pair of projection 14d (only showing a projection 14d among Fig. 1) to clamp this mode of riveting with protuberance 14c.At this, this to projection 14d have respectively not with riveted joint with the opposed side 14d of protuberance 14c
o, so that the side 14d of the projection 14d of a side
oSide 14d with the projection 14d of opposite side
oBetween the distance mode that is substantially equal to the width dimensions of groove part R a pair of projection 14d is set.Each side 14d of a pair of projection 14d
oShape corresponding to the shape of the opposed sidepiece 8a of a pair of bluff piece 8 that forms groove part R.At this, the opposed sidepiece 8a of bluff piece 8 becomes front end as shown in Figure 2, its length direction than the more mutual close curved shape of its length direction intermediate portion.
So, fill up 14 outward by projection 14d being embedded 8 of a pair of bluff pieces and close on groove part R, and axially packing between this disk 1 and a pair of bluff piece 8 along disk 1.Thus, fill up 14 outward can not come off to the preceding extreme direction between two bluff pieces 8, promptly can not support on the clamp 5 to the mode that disk 1 radially comes off.
Thus, when break moves, the braking torque on will the occur in outer pad 14, the projection 14d of the back veneer 14a by outer pad 14 and with this projection 14d side 14d
oThe opposed sidepiece 8a of contacted bluff piece 8 is passed to clamp 5, so by non-rotating 2 of vehicle bear.In this case, the bluff piece 8 that bears braking torque is bluff pieces 8 of disk 1 gyratory directions outlet side.Disk 1 is when arrow A direction revolution as shown in Figure 1 and Figure 2, and the bluff piece 8 that bears braking torque is the bluff pieces in left side among the figure.
The retainer spring 16 that matches with a pair of bluff piece 8 is installed on the back veneer 14a of outer pad 14 by the riveted joint of aforementioned riveted joint with protuberance 14c.Outer pad 14 can reciprocatingly be bearing on the clamp 5 by the axis G direction of this retainer spring 16 along disk 1.
This retainer spring 16 is inserted into the riveted joint of outer pad 14 among the 16a of hole with protuberance 14c, and riveted joint by the way is fixed to the riveted joint of protuberance 14c on the back veneer 14a of outer pad 14.So the front end 16f of arm 16c matches with the notch portion 8b that forms respectively on a pair of bluff piece 8 respectively.Thus, the front end 16f of the arm 16c that convex is extended has limited it by the wall portion of notch portion 8b and has moved, and makes outer pad 14 to the disk 1 axis G direction application of force.
In addition, the downside end face 8b Elastic Contact of a pair of engagement portion 16e and a pair of bluff piece 8 prevents that outer pad 14 from radially rocking at disk 1.Moreover the thickness of slab of retainer spring 16 0.5mm preferably, but be not limited to this, also can be set at 0.4-0.6mm.
The back veneer 15a of interior pad 15 is bigger than the width of the disk passage 7 of clamp 5 in the length of length direction.Back veneer 15a, is extending in the outstanding mode of disk passage 7 two side ends (left and right side of Fig. 1, Fig. 2) from clamp 5 along the mating face of the interior pad 15 of disk 1 in the both sides of length direction.And, the extension part 15c of each side of back veneer 15a vis-a-vis with liner plate 15b engaging portion, as shown in Figure 2, also be provided with at the radially outstanding of disk 1.Recess 15e is formed between the extension part 15c of back veneer 15a both sides, with the space as the disk passage 7 that can hold clamp 5.In addition, at this extension part 15c opposite side opening slot 15d is arranged, disk passage 7 sidepieces of the clamp 5 between between recess 15e groove 15d therewith face mutually.
On the other hand, pad guide portion 17 in the both sides of the disk passage 7 of clamp 5 form, it is outstanding from the both sides of disk passage 7, can be formed on aforementioned in groove 15d on the extension part 15c of pad on the 15 back veneer 15a engage, and, bluff piece 8 sides from oil hydraulic cylinder 6 side direction and extend along the axis G (above-below direction of Fig. 1) of disk 1.
And the interior therewith pad guide portion 17 of the groove 15d in aforesaid being formed on the pad 15 back veneer 15a extension part 15c engages, and interior pad 15 supports on the clamp 5, and slidably leads on the axis G of disk 1 direction.In the present embodiment, the above-mentioned extension part 15c with groove 15d constitutes the joining portion.
As shown in Figure 5, the end face 17a of bluff piece 8 sides does not arrive disk 1 axis G direction (Fig. 5 left and right directions) front end of disk path 7 in interior pad guide portion 17.From the length E of outer pad abutted surface 8c to the end face 17a of bluff piece 8 sides of interior pad guide portion 17 of bluff piece 8 preferably be set at disk 1 thickness b add outside below the thickness a sum (a+b) of back veneer 14a of pad 14, (be E≤(a+b)).The position of the end face 17a of bluff piece 8 sides of pad guide portion 17 in setting like this, even (fill up the state of wear that 14 lining material 14b arrives operating limit outward) when filling up 14 full pads outward and all wearing and tearing, also can with in the sting groove 15d of 15 extension part 15c remain on the state that engages with interior pad guide portion 17, thereby pad 15 in keeping really.
But, in fact, if the groove 15d of extension part 15c and interior pad guide portion 17 become the state of chimeric (overlap joint) about 3mm, promptly interior 15 the about 3mm of amount of lap that fills up, filling up guide portion 17 in then interior pad 15 remains on is on the clamp 5.Therefore, when the back veneer 15a thickness of interior pad 15 is assumed to 5mm, the pad assembly department only exposes 5mm-3mm=2mm from the end face 17a of interior pad guide portion 17 then, promptly, in this case, can be E (mm)≤(a (mm)+b (mm)+2 (mm)) with the set positions of the end face 17a of bluff piece 8 sides of interior pad guide portion 17.
As shown in Figure 1, spring washer 18 is contained between the groove 15d and interior pad guide portion 17 of extension part 15c in arrow A direction the place ahead (Fig. 2 left side), fills up 15 in making and clamp 5 are exerted pressure in the arrow A direction.
In the disk type braker of said structure, clamp 5 support to quick condition on non-rotating 2 of vehicle with cylindrical piece 4 is direct by guiding.In addition, setting is interior pad guide portion 17 side-prominent and that extend along disk 1 axis G from 7 liang in disk passage, extension part 15c is arranged on the back veneer 15a of interior pad 15, and fill up the groove 15d of guide portion 17 on this extension part 15c, form inserting, extension part 15c is joined in the interior pad guide portion 17, thereby interior pad 15 can reciprocatingly positively support on the clamp 5 along disk 1 axis G direction.So, in the braking torque that takes place on the pad 15 by disk 1 gyratory directions inlet side (when disk 1 turns round in the arrow A direction, Fig. 2 right side) interior pad guide portion 17 is passed on the clamp 5, and by through guiding with cylinder part 4 be connected the bolt 3 that conjugate foramen portion 10 that these oil hydraulic cylinder portion 6 both sides form engages, be that non-rotating 2 on the vehicle that fills up guide portion 17 downsides bears by the disk side that is positioned at conjugate foramen portion 10.Therefore, as shown in Figure 5, in pad guide portion 17 and through guiding be bonded on parts 4 in the clamp 5 conjugate foramen portions 10 bolt 3 the mounting point of non-rotating 2 on vehicle disk 1 axially near setting (in other words, roughly along perpendicular to disk 1 axially extended straight line setting), thus the influence that acts on the moment on the clamp 5 can be reduced by the slip of internally filling up 15 disk 1 mutually.Mainly be, because the L size is (at the disk axial direction among Fig. 4, in on the pad guide portion 17 in pad 15 engagement positio and guiding with the size between cylinder part 4 and non-rotating 2 connecting position of vehicle) can set shortlyer, thereby when slip, can reduce the moment that acts on the clamp 5.
Because omitted the carriage of necessity in the prior art, above-mentioned interior pad 15 also can positively support on the clamp 5, thereby because of having omitted carriage installation weight is alleviated, device is compact simultaneously, and then cost is reduced.
In the oil hydraulic cylinder portion 6 of clamp 5, corresponding with a pair of bluff piece 8, left and right symmetrically forms a pair of discharge pipe boss 11 and a pair of pipe arrangement boss 12 respectively, by this structure, clamp unit portion 10 is strengthened with the linking portion of oil hydraulic cylinder portion 6, and keeping strength balance, thereby avoid local deformation.In addition, a pair of discharge pipe boss 11 and a pair of pipe arrangement boss 12 left and right symmetricallies are formed on the clamp 5, by carry out hole processing selectively on the discharge pipe boss 11 of left and right sides either side and pipe arrangement boss 12, the versatility of clamp 5 that can be used in left side, right side wheels is good, and boosts productivity.
In addition, in the disk type braker of this omission carriage type, the wearing and tearing of disk gyratory directions outlet side part are easy in the pad outward, by the eccentric wear damage that may cause outer pad.To this, in the disk type braker of present embodiment, the retarding torque of pad 15 is born by the 1 gyratory directions inlet side of disk in the clamp 5 (Fig. 1 right side) in making, bear by the 1 gyratory directions outlet side of disk in the clamp 5 (Fig. 1 left side) and fill up 14 retarding torque outward, thereby on clamp 5, produce the left-handed moment shown in Fig. 1 arrow B.In addition, in the disk type braker of present embodiment, fill up outside on 14 the retarding torque that produces by the bluff piece 8 of disk 1 gyratory directions outlet side (shown in Fig. 1 arrow A during the direction revolution at disk 1, the bluff piece 8 in Fig. 1 left side) when bearing, because the bluff piece 8 of outlet side is easily deformable, bluff piece 8 ratios with inlet side can open (direction from disk 1 to the front end of bluff piece 8 that leave) significantly.For this reason, fill up outside exert pressure on the pad surface at disk 1 gyratory directions outlet side in 14, inlet side place roughly the same, thereby the eccentric wear that can prevent outer pad 14 decreases.
In addition, when the retarding torque that produces on above-mentioned outer pad 14 is born by the bluff piece 8 of disk 1 gyratory directions outlet side, outlet side bluff piece 8 produces big and wide distortion than inlet side bluff piece 8, and this carries out COMPUTER CALCULATION research to be verified by the applicant with finite element method (FEM).
In the above-described embodiments, in pad guide portion 17 be to extend at the end face 17a of bluff piece 8 sides along the braking surface of disk 1, but available structure shown in Figure 7 is replaced, promptly the disk 1 on the bluff piece 8 sides part of interior pad guide portion 17 radially inwardly is formed with plane of inclination 19 on the part, (angle of disk 1 braking surface relatively) θ is 20 °～30 °, thereby can improves assembling performance towards disk 1 radially inner tilt angle in this plane of inclination 19.In addition, tiltangle can be set at 0 °～45 °.
That is, interior pad 15 at first engages its extension part 15c and carries out towards the assembling on the clamp 5 with interior pad guide portion 17.On the other hand, because it is generally short (particularly to the length E of the end face 17a of bluff piece 8 sides of interior pad guide portion 17 from the outer pad abutted surface 8c of bluff piece 8, especially short when disk 1 is solid disk), as shown in Figure 7, relative bluff piece 8, interior pad 15 becomes heeling condition, and extension part 15c is engaged with interior pad 15.At this moment, by the above-mentioned plane of inclination 19 that on the end face 17a of interior pad guide portion 17, forms, when in interior pad 15 is assembled to, filling up on the guide portion 17, improved its assembling performance.At this moment, at first by the interior pad 15 close disk channel parts 7 of radially inwardly making of disk 1, the top of the extension part 15c of interior pad 15 is internally filled up guide portion 17 mutually and is positioned at disk 1 radial outside, make disk channel part 7 in the recess 15e of interior pad 15, the end face 17a of the slot part 15d of pad 15 and interior pad guide portion 17 is opposed in must making, but when this operation, can make only form plane of inclination 19 and not in the axial formation of disk 1 length of disk channel part 7 of pad guide portion 17 have more than needed, the surface that is positioned at bluff piece 8 sides and the bluff piece 8 of pad 15 interfere in avoiding, or the surface that is positioned at oil hydraulic cylinder 6 sides and the pad guide portion 17 of pad 15 interferes in avoiding, thereby the assembling performance of pad 15 in improving.
In the above-described embodiments, fill up on the same one side of 15 middle bodies in extension part 15c in being formed on the back veneer 15a length direction sidepiece of pad 15 is formed on, be so-called flush, but alternately, extension part also be fine with respect to middle body towards the structure of leaving disk 1 direction bending.Usually, the wheel and the gap between the clamp 5 that are arranged on bluff piece 8 sides are narrower, limited of the extension of interior pad guide portion 17 towards bluff piece 8 sides, even but in this case, disk 1 direction is crooked to be provided with towards leaving with respect to the center by the above-mentioned extension part that makes, the groove 15d of extension part 15c is engaged with interior pad guide portion 17, thereby pad 15 remain on the clamp 5 really in making.
In the above-described embodiments, retainer spring 16 is filled up 14 back veneer 14a outwardly go up that to install be that riveted joint by being arranged on the back veneer 14a is carried out with protuberance 14c, but can be substituted with the mode of screw installation.In addition, the rising portion that engages with the last projection 14d that is provided with of back veneer 14a is positioned on the retainer spring 16, engages with projection 14d by rising portion, also retainer spring 16 can be installed on the back veneer 14a.
Above-mentioned first embodiment's of the present invention disk type braker structure as mentioned above, join by assembly department on the pad in being formed on and interior pad guide portion on the disk channel part that is arranged on clamp and to be incorporated in disc shaft to slide-and-guide, and the groove formation portion that is formed on bluff piece on jut and the clamp on the outer pad engages, outer pad is supported on the clamp, so fill up in supporting really and outer pad.Therefore, can omit carriage, clamp are bearing in quick condition on non-rotating of vehicle, thereby can support interior pad, and omit carriage, just can in alleviator weight, make the apparatus structure compactness and then reduce cost.
Have, when break moved, because the bluff piece of disk outlet side bears torque, therefore with respect to the bluff piece of inlet side, the outlet side bluff piece easily was out of shape shown in Fig. 1, Fig. 4 dotted line outwardly again.
For this reason, the pad surface pressure of disk gyratory directions outlet side is littler than the pad surface pressure of its inlet side, and makes outer pad surface pressure even, and then suppresses the generation that eccentric wear decreases, thereby can prevent chatter sound and brake noise.
Outside the bluff piece of the disk gyratory directions outlet side disk gyratory directions outlet side by outer pad partly bears during the pad torque, outside on one's body the advance capital for, will with the linking part of the disk gyratory directions outlet side of outer pad part and clamp as fulcrum, the moment of pad has played impels its contacted effect of disk towards disk gyratory directions inlet side part.Though this moment is less, owing to above-mentioned impelling towards the contacted effect of disk of disk gyratory directions inlet side part arranged, therefore can make the generation that the pad surface pressure is even and then the inhibition eccentric wear decreases, can prevent that chatter sound and brake noise from taking place.
When in the disk gyratory directions outlet side of the clamp of disk gyratory directions outlet side part by interior pad partly bears, filling up torque, the disk gyratory directions inlet side part of interior pad contacts with clamp, this part becomes fulcrum, on one's body interior advance capital for, internal the contact moment of the pad that suppressed of the disk towards disk gyratory directions outlet side part of pad of effect does not only produce in impelling pad towards the moment of the gyratory directions inlet side contacted pad of disk partly.
By pad guide portion in setting, make from the outer pad abutted surface of bluff piece to the bluff piece side end face of interior pad guide portion length less than disc thickness with fill up back veneer thickness sum outward, when even the full pad of outer pad weares and teares, the state that the pad joining portion engages with interior pad guide portion in also keeping, thus can maintain interior pad really.
By the disk diameter in the bluff piece side part of pad guide portion in the plane of inclination is formed on to the inside on the part, when interior pad assembling, the bluff piece part of interior pad guide portion can not interfered interior pad, thus pad assembling performance in can improving.
By corresponding a pair of bluff piece in oil hydraulic cylinder portion respectively left and right symmetrically a pair of discharge pipe boss part and a pair of pipe arrangement boss part are set, strengthened the attachment portion of conjugate foramen portion and oil hydraulic cylinder portion, and kept strength balance, thereby avoided local deformation.
In addition, be set to from engaging part to the direction bending of leaving disk by the structure that makes the joining portion with the lining material of the back veneer of interior pad, both made and limited interior pad guide portion under the situation of bluff piece side extension, the joining portion of pad engages with interior pad guide portion really in also making, and pad remains on the clamp in making really.
According to Figure 11 the second embodiment of the present invention is described below.
Figure 11 shows the disk type braker with the same no carriage of first embodiment, and it is the break that the position of external pad gyratory directions is limited.By will being inserted into slidably on the pairing left and right assembly department 102 that is arranged on the clamp lower end from the rest pin (not shown) of non-rotating extension of vehicle, but clamp 101 are installed at the axial floating ground of discal rotor D on non-rotating of this vehicle.Clamp 101 have from the oil hydraulic cylinder portion (not shown) of interior dress piston and stride across a pair of bluff piece 104 that disk channel part 103 that discal rotor D extends and the radius inward direction from the front end of this channel part 103 towards discal rotor D extend, the interior pad 105 that is arranged on discal rotor D inboard at these dish type channel part 103 upper supports, and the outer pad 106 that is arranged on the discal rotor D outside at these a pair of bluff piece 104 upper supports.

Describe the 3rd embodiment below with reference to the accompanying drawings in detail.
Figure 12～Figure 14 shows the disk type braker of the 3rd embodiment's no carriage.Since the basic structure of the disk type braker of present embodiment with shown in Figure 11 be identical, at this, same parts are represented with prosign.In the present embodiment, tubular rest pin 121 by break-through bolt 122 wherein with discal rotor D axially upright mode be fastened on non-rotating (toggle) 120 of vehicle.By clamp assembly department 102 can be joined on the aforementioned rest pin 121 with being free to slide, make clamp 101 (Figure 14) axially movably is being set towards discal rotor D.
Clamp 101 are provided with the oil hydraulic cylinder portion 123 of dress piston in assembly department 102 tops, and this oil hydraulic cylinder portion 123 is provided with: be used to wear the into pipe arrangement boss 125 of oil drain out 124, be used for to the row's of giving hydraulic oil in the chamber of receiving piston for oil drain out 124; And the discharge pipe that is used to discharge the escape cock 126 of air in the aforementioned cavities is housed with boss 127.This disk type braker also is the braking moment of being born aforesaid interior pad 105 and outer pad 106 by clamp 101, and when the balance of clamp 101 left and right directions was not good, there was the moderate finite deformation generation clamp 101 parts.Therefore, in the present embodiment, so that a pair of aforesaid pipe arrangement boss 125 and discharge pipe boss 127 (Figure 13) respectively to be set with respect to left and right directions center line symmetrical manner, and aforesaid oil drain out 124, the escape cock 126 given be set on each right any, and then clamp 101 are also strengthened by the stiffening element 128 that is erected at 102 of left and right sides assembly departments with aforementioned bolt 122.
The aforementioned dish type path 10 3 of clamp 101 strides across discal rotor D from the upside of above-mentioned oil hydraulic cylinder portion 123 and extends to outside it, and aforesaid a pair of bluff piece 104 is arranged on the front end of this dish type path 10 3.Interior pad 105 and outer pad 106 each free aforementioned back boxing 105a, 106a and liner plate material 105b, the 106b formation that engages with this back boxing 105a, 106a one surface.Interior pad 105 is that the ear 107 as extension part supports on the clamp 101 with pad guide portion 108 tablings of disk channel part 103 on aforesaid its back boxing 105a both sides with being arranged on.This assembling is to utilize the pad guide portion 108 as interior pad guide portion to be positioned at the end face 108a (Figure 14) of bluff piece 104 sides and the gap between bluff piece 104 back sides, and ear's 107 embedding pad guide portions 108 are formed.In addition, in the joining portion, the left and right sides between the ear 107 of pad guide portion 108 and interior pad 105, pad spring 129 is installed on the joining portion of rotor inlet side, pad 105 relied on the rotor outlet side and clings to the joining portion opposite side in it made, thus the braking moment that takes place on the pad 105 in can bearing effectively.
In addition, filling up 106 the circular-arc parts 111 of groove 110 by will being darted at 104 of a pair of bluff pieces on pairing left and right projection 109 and the clamp 101 on aforesaid its back boxing 106a outward engages and supports on the clamp 101.The fixed-site of outer pad 106 is fixed to by its center that back boxing 106a goes up and the spring 130 of fixing its two ends on the surface of each bluff piece 104 is finished (Figure 13).Aforementioned spring 130 external pads 106 back boxing 106a fixedly are, after putting the hole that is set on the spring 130 on the cylindrical boss 131 (Figure 12) of conduct riveted joint with protuberance that is set to back boxing 106a center of dashing forward, form by the front end of riveting this boss 131.This spring 130 is exerted pressure for the projection 109 of outer pad 106 and it is entered in the groove 110, thus, fill up the state that 106 back sides that are positioned its back boxing 106a and bluff piece 104 usually join outward.
At this, fill up outward 106 a pair of projection 109, with respect to the radially outward displacement of the circular-arc mating face 114 of groove 110 towards discal rotor D, thereby do not overlap with the terminal edges 113 by discal rotor D center of the circular-arc part 111 of groove 110.In the present embodiment, because the circular-arc mating face 114 of such projection 109 is removed from the terminal edges 113 of groove 110 circular-arc parts 111, thereby downcut the lower portion of projection 109, the section size that makes projection 109 during than second embodiment (Figure 11) little, do not make that projection 109 is whole also to be fine towards the displacement of discal rotor D radially outward but do not change the section size.
In the disk type braker of said structure, when supplying with hydraulic oil by giving in the chamber of clamp 101 for oil drain out 124, when making piston-advance not shown in the figures, promoted by this piston, pad 105 is pressed on discal rotor D one side in making, and when it retreated, clamp 101 retreated, make its bluff piece 104 will fill up 106 outward and be pressed on the opposite sides of discal rotor D, produce fixed braking force.At this moment, the retarding torque that produces on the interior pad 105 is born by pad guide portion 108, is born by the circular-arc part 111 of groove 110 and fill up the retarding torque that produces on 106 outward.
In addition, fill up 106 outward the limited part 112 that is arranged on above its back boxing 106a is contacted with the inner face 103a of the disk channel part 103 of clamp 101, thereby limited the position on its gyratory directions.Thus, when outer pad 106 was pushed on the rotating discal rotor D of arrow B direction, the limited part 112 of rotor outlet side shown in Figure 12 contacted with the inner face 103a of disk channel part 103, has limited the revolution of outer pad 106.As a result,, fill up outside and produce the moment of turning right on 106 as fulcrum with the inner face 103a connecting position of limited part 112 and aforementioned disk channel part 103, generation will be filled up the 106 power F that radially push away towards discal rotor D outward downwards.So, because the circular-arc mating face 114 of a pair of projection 109 relative grooves 110 of outer pad 106, decorporate towards discal rotor D radially outward from circular-arc part 111 terminal edges 113 of above-mentioned groove 110, even thereby big following thrust (braking force) F is repeat when load, also can the not nip mating face 114 of outer pad 106 projections 109, aforementioned terminals edge 113.
Disk type braker according to above-mentioned the 3rd embodiment, even big braking force is accepted on repeat ground, because keeping the clamp groove and filling up the state that projection engages sleekly outward, pad can not embarrassed outside clamp unload when changing, thereby prevents the phenomenon that later maintenance is bad.
Below, the fourth embodiment of the present invention is described, the 4th embodiment has to prevent the disk type braker of brake noise with partition.
In aforesaid first～the 3rd embodiment's disk type braker, the riveted joint of pad back veneer central authorities fixed plate (spring) with riveted fixing on the projection outside described being arranged on, and makes outer pad supports to the bluff piece of the clamp with oil hydraulic cylinder by fixed plate.So, on this disk type braker, be provided with when preventing that brake noise is used partition, for example can consider, bluff piece is set on partition, the mode of embracing pad with this bluff piece supports to partition on the pad, perhaps on pad, form a plurality of riveted joint projections, partition is supported on the pad with fixed plate by a plurality of riveted joints are riveted with projection.

And when use was arranged on mode that bluff piece on the partition has pad in arms partition is supported to pad and goes up, because bluff piece is arranged on the partition, production process increased, thereby has improved the cost of device.
In addition, when using a plurality of riveted joints partition and fixed plate together to be supported to pad and go up, can not carry out the single-piece replacing of partition, thereby maintenance is bad with projection.
Figure 22 and embodiment illustrated in fig. 23 in, because of the length D of fixed plate 211 sets to such an extent that (S＜D), change so can not carry out the single-piece of partition 209, its maintenance is also bad greater than the length S of window 210.And, as the words of fixed claw 212 are not set, though can carry out the single-piece of partition 209 changes, but when fixed claw 212 not being set, partition 209 can not be pressed on the outer pad 204, will outside fill up 204 be fixed to clamp 202 when, partition 209 is inoperative, for example can resemble the outside that is positioned at clamp 202 (a pair of bluff piece 203) shown in Figure 23, the problem of assembling difficulty takes place.
The 4th embodiment's purpose is to overcome the problems referred to above, and a kind of disk type braker that the partition single-piece is changed that easily carries out is provided.
For achieving the above object, the 4th embodiment comprises: pad, pack into disk and being arranged between a pair of bluff piece on the clamp, back veneer substantial middle portion at this pad is formed with the riveted joint projection, be formed with simultaneously this riveted joint born portion with the torque of a pair of prominent shape of projection in the middle of being arranged on, aforesaid roughly rectangular pad along with the direction setting of aforementioned disk diameter to approximate vertical; Fixed plate, constitute with pawl and pushing portion by fixing part, a pair of fixed plate, wherein said fixing part is fixed on the aforementioned pad with projection by aforementioned riveted joint, described a pair of fixed plate with the pad length direction both sides of pawl in this fixing part to aforementioned disc shaft to upright and its front end crookedly contact with aforementioned a pair of bluff piece, by contacting with aforementioned a pair of bluff piece, aforementioned pad is supported on the aforementioned clamp movably, form between described pushing portion and the aforementioned pad and give fixed gap, extend to a side vertical with filling up length direction from aforementioned fixing part; Further, anti-brake noise partition is set, this partition is microscler along aforementioned pad roughly, be formed with at the long limit opening of a side and extend to the groove of opposite side long leg, be provided with the notch that connects aforementioned grooves and engage, and the opposite side long leg inserts in the aforementioned gap with the aforementioned a pair of torque portion of bearing.
Below, the 4th embodiment's disk type braker is described in detail in detail according to Figure 15～Figure 21.Represented in addition suitably omission among the figure when it illustrate for this with prosign with Figure 22, parts shown in Figure 23, parts, part that part is identical.
In Figure 21, clamp 202 are by the oil hydraulic cylinder portion 213 of the piston (not shown) that is provided with the hydraulic pressure advance and retreat, with these oil hydraulic cylinder portion 213 inboard slide parts 214 that link to each other, support to slidably on the non-rotating part of vehicle (toggle) 120, stride across the disk channel part 215 that disk 201 extends from oil hydraulic cylinder portion 213, and constitute from a pair of bluff piece 203 that these disk channel part 215 front end edge disks 210 extend radially inwardly.Pad 216, outer pad (pad) 204 in being equipped with respectively between aforementioned disk 201 and the oil hydraulic cylinder portion 213 and between aforementioned disk 201 and a pair of bluff piece 203, fill up 204 outward and axially movably support among Figure 21 on the toggle (having omitted among Figure 21) as non-rotating part not shown in the figures with clamp 202 1 disk 201 that coexists respectively interior pad 216.So the retarding torque in occurring on pad 216 and the outer pad 204 is directly born by the clamp 202 of pad 216 in the supporting and outer pad 204.
Fixed plate 211 is installed on the outer pad 204 with projection 207 by riveted joint.
Fixed plate 211 roughly is made of with pawl 218 and pushing portion 220 fixing part 217, a pair of fixed plate, and wherein fixing part 217 is the fixing parts that are roughly rectangle that are fixed on the outer pad 204; A pair of fixed plate is to fill up 204 length direction two ends from this fixing part 217 China and foreign countries axially (the about direction of Figure 15 paper) is upright, its forward end is crooked and join with aforementioned a pair of bluff piece 203 towards disk 201 with pawl 218, and, outer pad 204 is supported on the clamp 202 movably with spring force by joining with aforementioned a pair of bluff piece 203; Pushing portion 220 extends to pushing portion with the perpendicular both sides (side and opposite side) of outer pad 204 length directions from fixing part 217, itself and outside fill up the gap 219 that is formed with given size (thickness size 0.6～0.8+ tolerance α (trace) [mm] of partition 209 described later) between 204.Fixed plate with pawl 218 roughly by the upright rising portion 218a that links to each other with fixing part 217, and be roughly with this rising portion 218a that 90 ° of bendings are connected and with a pair of bluff piece 203 contacted corpus unguis 218b formations.
Among Figure 15 and Figure 21, label 209 is roughly along outer pad 204 and be offset flat shape, and thickness is the anti-brake noise partition of 0.6～0.8mm.Be formed with in the long leg 209a upper shed of a side (Figure 15 downside) on the partition 209 and extend near the long leg 209b of opposite side (Figure 15 upside) groove 221.In addition, link to each other, on partition 209, be formed with pair of notches portion 222 with groove 221.It is corresponding that portion 208 is born in the shape of notch 222 and torque, and notch 222 clamp a pair of torque bear in the portion 208 disk 201 radially in external lateral portion and clamp the steering portion radially perpendicular (Figure 15 left and right side part) with disk 201.And the long leg 209b of opposite side inserts in the aforementioned gap 219, thus, has limited partition 209 in the axial displacement of disk 201.
So assemble aforementioned partition 209 as follows.Promptly, at first as Figure 15 and shown in Figure 180, the 218A of pair of upright portion is tiltedly axially entered in the opening portion 221A disk 201, partition 209 guided be inserted into rising portion 218a and a pair of torque is born between the portion 208, then, as Figure 16 and shown in Figure 19, the long leg 209b of opposite side is inserted in the gap 219.Then, as Figure 17 and shown in Figure 20, relative disk 201 axially for the long leg of partition 209 1 sides of heeling condition places outer pad 204 sides, is made notch 222 clamp that portion 208 is born in torque and finishes assembling.
In the disk type braker of said structure, engage by notch 222 is born portion 208 with the torque of outer pad 204, limited partition 209 disk 201 radially and with radially perpendicular direction on displacement.In this case, radially to reach restriction with radially perpendicular direction displacement at disk 201 be to bear carrying out at the end 208a of disk 201 radial side and with the end 208b of perpendicular side radially of portion 208 by torque to partition 209.
And the pushing portion 220 of fixed plate 211 contacts with the long leg 209a of partition 209 1 sides, thereby has limited partition 209 in the axial displacement of disk 201.In this case, can maintain the displacement restriction of the degrees of freedom (amount of movement) of tolerance α.
As mentioned above, owing to can be set on the partition 209 fixing, the fixing cost that is set on the partition 209 with bluff piece is not improved thereby can not bring with bluff piece to the displacement restriction of partition 209.In addition, the assembling of partition 209 be adopt aforesaid do not interfere other parts (order of Figure 18-Figure 20) is assembled, but also can adopt the order roughly opposite with above-mentioned assembling sequence of not interfering other parts when dismounting by Figure 15-Figure 17.Therefore, can easily change single-piece partition 209, this is very easily.
In addition, because partition 209 is that axially to maintain tolerance with relative disk 201 be that the mode of the degrees of freedom of α is limited, thereby, improved anti-brake noise performance along with the action of clamp 202 bluff pieces 203.
In the present embodiment, pushing portion 220 is along extending with the perpendicular both sides (side and opposite side) of outer pad 204 length directions on fixed plate 211, but when filling up on 204, the variation of above-below direction can take place, improve assembling performance outside fixed plate 211 is assembled to.Moreover, only pushing portion 220 is being set, and the setting of omitting the pushing portion of opposite side also can with the perpendicular side (Figure 15 upside) of outer pad 204 length directions.
The 4th embodiment's disk type braker is made of said structure, engages with the pad torque portion of bearing by notch, limited partition disk diameter to and with the radially displacement of perpendicular direction.And then the pushing portion of fixed plate contacts with the long leg of partition one side, limited partition disc shaft to displacement.In this case, by gap 209 being set bigger slightly, can make the partition displacement restriction under the state of only holding certain degrees of freedom than partition thickness.
The displacement restriction of partition can be arranged on the partition and realize fixing with bluff piece, will not fix the cost that is arranged on the partition with bluff piece and improve thereby can not produce.In addition, can insert the fixed side part of the bluff piece of fixed plate at the groove of the long leg opening that is positioned at partition one side, can not driedly scratch other parts thus and carry out installation, the dismounting of partition, can easily carry out the single-piece of partition and change, maintainability is improved.
