Detailed description of the invention
Embodiment 1
Seeing that Fig. 1 to Figure 11, embodiment 1 have amphidisc 1, amphidisc 1 is respectively placed in the web left and right sides of wheel 2, is connected by bolt 3 between disk body 1 with wheel 2.
The installed surface of disk body 1 is provided with circumference and is uniformly distributed and for spaced featherway 1-1 and slide block slot 1-3, and the total quantity of featherway and slide block slot determines according to product specification.The web of wheel 2 is provided with the through hole 2-1 that circumference is uniform.The disk body 1 of the present embodiment is provided with 6 featherway 1-1 and 6 slide block slot 1-3, and correspondingly, the web of wheel 2 is provided with 12 through hole 2-1.
The present embodiment is respectively provided with boss 1-4, featherway 1-1 on the position of corresponding featherway 1-1 and slide block slot 1-3 on the installed surface of disk body 1 and is arranged on round boss, and slide block slot 1-3 is arranged on fan-shaped boss.Being additionally provided with radiating ribs 1-5 on the installed surface of disk body 1, radiating ribs 1-5 can not be above boss 1-4.
On described disk body 1 and be equipped with bolt hole 1-2, bolt hole 1-2 leading to one end of rubbing surface corresponding to the bottom of every featherway 1-1 and slide block slot 1-3 is counter sink 1-2-1.
The two side 1-1-1 of described featherway 1-1 faces directly, corresponding every featherway 1-1 is provided with a hollow feather key 4, feather key 4 is made up of feather key head 4-1 and feather key bar 4-2, feather key head 4-1 and feather key bar 4-2 is an entirety, and the two sides 4-1-1 of feather key head 4-1 is respectively and featherway corresponding the facing directly of sidewall 1-1-1.Feather key head 4-1 loosens and is arranged in featherway 1-1, and feather key bar 4-2 inserts in through hole 2-1 corresponding on the web of wheel 2, and the length of feather key bar 4-2 is without departing from the half of web through hole 2-1 length.Feather key 4 can be made the most slidably along featherway 1-1, and in circumference, the gap of feather key head 4-1 and featherway 1-1 is arranged, it is ensured that during bolt Joint failure, disk body 1 circumferentially rotates under Braking and contacts with feather key head 4-1, thus is undertaken braking torque by feather key 4.Distance between the two sides 4-1-1 of the distance between the two side 1-1-1 of featherway 1-1 i.e. feather key groove width L1 and the feather key head 4-1 i.e. difference of feather key head breadth L2 is less than 0.1mm.
Described bolt bolt hole 1-2 from a disk body 1 inserts, through the cavity 4-3 of two feather keys 4 insert on another disk body 1 relative to bolt hole 1-2 in fixed by nut 3-2, bolt 3 is dynamic cooperation with the cavity 4-3 of bolt hole 1-2, two feather keys 4, the head 3-1 and nut 3-2 of bolt 3 is respectively in the counter sink 1-2-1 of the corresponding bolt hole of amphidisc, is cased with spacer 5 at the head 3-1-1 of bolt 3-1.
For preventing disk body from causing feather key bolt 3 displacement to touch feather key 4 because of expanded radially of being heated, centrage 3-z1 through the bolt of feather key is positioned at the radial direction nearly wheel center line 2a side of feather key centrage 4-z, and is 1～1.5mm with the deviation distance δ 1 of the centrage 4-z of feather key.Disk body, in the radial expansion process that is heated, drives the bolt 3 through feather key radially to the side displacement away from radially nearly wheel center line 2a, so that the centrage 3-z1 of this bolt 3 is close with the centrage 4-z of feather key 4 or overlaps, is further ensured that brake safe.
The two side 1-3-1 of described slide block slot 1-3 faces directly, is provided with loosening slide block 7 in slide block slot 1-3, and the two sides of slide block 7 are respectively and slide block slot corresponding the facing directly of sidewall 1-3-1.Slide block 7 has connecting hole 7-1, and connecting between the connecting hole 7-1 of the opposing slider 7 being separately mounted to amphidisc has hollow power transmission pin 6, and power transmission pin 6 passes through hole 2-1 corresponding on wheel web.Slide block 7 can be made the most slidably along slide block slot 1-3, and in circumference, slide block 7 is arranged with the gap of slide block slot 1-3, it is ensured that during bolt Joint failure, disk body 1 circumferentially rotates under Braking and contacts with slide block 7, thus is undertaken braking torque by slide block 7.Distance i.e. slide block groove width H1 between described slide block slot two side 1-3-1 is less than 0.1mm slightly larger than the distance i.e. slide block width H2 between the two sides 7-1-1 of slide block 7, slide block groove width H1 with the difference of slide block width H2.
Described bolt bolt hole 1-2 from a disk body 1 inserts, through the pin chamber 7-1 of power transmission pin 7 insert on another disk body 1 relative to bolt hole 1-2 in, and fixed by nut 3-2, bolt 3 is dynamic cooperation with bolt hole 1-2, pin chamber 7-1, the head 3-1 and nut 3-2 of bolt 3 is respectively in the counter sink 1-2-1 of the corresponding bolt hole of amphidisc, is cased with spacer 5 at the head 3-1 of bolt 3-1.
For preventing disk body from causing this bolt 3 displacement to touch power transmission pin 6 because of expanded radially of being heated, centrage 3-z2 through the bolt of power transmission pin is positioned at the radial direction nearly wheel center line 2a side of power transmission pin center 6-z, and is 1～1.5mm with the centrage 6-z deviation distance δ 2 of power transmission pin.Disk body, in the radial expansion process that is heated, drives the bolt 3 through power transmission pin radially to the side displacement away from wheel center line 2a, so that the centrage 3-z2 of this bolt is close with the centrage 6-z of power transmission pin 6 or overlaps, is further ensured that brake safe.
This brake disc arrangement is in use, when the frictional force that bolt 3 fastening produces is not enough to the brake force overcoming brake clamp to apply, disk body 1 rotates under braking torque effect, driving side 4-1-1 and the featherway sidewall 1-1-1 laminating of feather key head, the side 7-1-1 of slide block and slide block slot sidewall 1-3-1 fits.Loosen respectively due to bolt again and be placed in the cavity 4-3 of feather key and the pin chamber 6-1 of power transmission pin, and when ensureing bolt Joint failure by physical dimension and tolerance design, when disk body drives feather key 4 and slide block 7 circumference to slide, bolt does not still contact with feather key and power transmission pin, braking torque is undertaken by slide block and feather key, thus ensures that bolt will not directly bear shearing force all the time.Disk body braking is when bearing thermic load effect, disk body can radially free wxpansion, thus reduce brake disc because bearing structural stress and deformation causes to feather key and the active force of power transmission pin, feather key 4 and power transmission pin 6 shielded.
The assemble method of this device is as follows: be first positioned on assembly platform by first disk body 1, and makes the installed surface of disk body 1 upward.In the slide block slot 1-3 of disk body installed surface, place slide block 7, in featherway 1-1, place feather key 4, the pin-and-hole 7-1 of slide block 7 installs power transmission pin 6, in the pin chamber 6-1 of power transmission pin 6 and the chamber 4-3 of feather key 4, respectively penetrates positioning tool.Subsequently, hang in wheel, according to the location of positioning tool, the feather key 4 respective through hole on wheel web being respectively aligned on first disk body and power transmission pin 6, put down wheel, make the web surface of wheel web be close to the boss face of first disk body.And then, slide block 7 needed for being installed by second disk body is enclosed within power transmission pin 6, and make the direction of the sidewall 1-3-1 of the side 7-1-1 and slide block slot 1-3 of this slide block 7 consistent, feather key 4 needed for simultaneously being installed second disk body inserts in through hole corresponding on wheel web, and makes the 4-1-1 direction, side of feather key head 4-1 on this feather key 4 consistent with the sidewall 1-1-1 direction of featherway 1-1.Finally, the installed surface of second disk body is downward, and according to the location of positioning tool, the featherway 1-1 and slide block slot 1-3 of second disk body are respectively fallen on feather key 4 and slide block 7, thus realize the location of second disk body, and tighten assembling by prescribed torque intersection.
