The junction has a plurality of communication holes defined therein which provides communication between opposite sliding surfaces of the disk element.

Description
-
- The present invention relates to a disk brake having a disk rotor which can be braked by a brake caliper.
-
- Disk brakes which have a disk rotor which can be braked by a brake caliper are well known in the art as a brake system for a motor vehicle such as an automobile or the like. The disk rotor may be a solid disk which comprises a single circular plate or a ventilated disk which comprises two annular circular plates with a cooling air passage defined therebetween.
- FIG. 7 of the accompanying drawings schematically shows a disk brake having a disk rotor in the form of a ventilated disk which is in general use. As shown in FIG. 7, when a braking force is applied from a brake caliper 2 to a ventilated disk 1, the speed of rotation of a
wheel 4 which is fastened to the ventilated disk 1 bywheel bolts 3 is reduced. - The ventilated disk 1 comprises a
hat 6 which accommodates ahub unit 5 supporting thewheel 4 and a disk element 7 for receiving a braking force from the brake caliper 2. The disk element 7 has first and second annularcircular plates cooling fins 10 and acooling passage 11 interposed therebetween. The second annularcircular plate 9 is integrally joined to thehat 6. - When a braking force is applied from the brake caliper 2 to the disk element 7 while the
wheel 4 is in rotation, the disk element 7 generates a considerable amount of heat by frictional contact with the brake caliper 2. At this time,cooling air 12 flows through thecooling passage 11 between the first and second annularcircular plates cooling fins 10 to cool the disk element 7. - The ventilated disk 1 is disposed in the
wheel 4. Therefore, while an inner slidingsurface 8a of the first annularcircular plate 8 is cooled bycooling air 13, an outer slide surface 9a of the second annularcircular plate 9 is not exposed to much cooling air, and cannot sufficiently be cooled. - Solid disk brake systems also suffer the same problem as with the ventilated disk 1.
- It is a major object of the present invention to provide a disk brake which is capable of uniformly and effectively cooling a disk element as a whole that receives a braking force from a brake caliper.
- The above and other objects, features and advantages of the present invention will become more apparent from the following description when taken in conjunction with the accompanying drawings in which preferred embodiments of the present invention are shown by way of illustrative example.
- FIG. 1 is a vertical cross-sectional view of a disk brake according to a first embodiment of the present invention;
- FIG. 2 is a fragmentary front elevational view of a solid disk of the disk brake shown in FIG. 1;
- FIG. 3 is a fragmentary side elevational view of the solid disk as viewed in the direction indicated by the arrow III in FIG. 2;
- FIG. 4 is a vertical cross-sectional view of a disk brake according to a second embodiment of the present invention;
- FIG. 5 is a fragmentary front elevational view of a ventilated disk of the disk brake shown in FIG. 4;
- FIG. 6 is a fragmentary side elevational view of the solid disk as viewed in the direction indicated by the arrow VI in FIG. 5; and
- FIG. 7 is a vertical cross-sectional view of a conventional disk brake.
-
-
- FIG. 1 shows in vertical cross section a
disk brake 20 according to a first embodiment of the present invention. - As shown in FIG. 1, the
disk brake 20 comprises asolid disk 24 as a disk rotor which rotates in unison with awheel 22 and abrake caliper 26 for applying a braking force to thesolid disk 24 to reduce the speed of rotation of thewheel 22. - The
solid disk 24 has an integral unitary structure which comprises ahat 28 and adisk element 30 which can be contacted by pads (not shown) of thedisk caliper 26. Thehat 28 has a central throughhole 34 defined axially therein which receives ahub unit 32. Thehat 28 also has a plurality offirst holes 36 and a plurality ofsecond holes 38 defined therein at given angular intervals around the through hole 34 (see also FIG. 2). - As shown in FIG. 1,
screws 40 are threaded through the respectivefirst holes 36 into thehub unit 32, thereby fastening thehub unit 32 to thehat 28.Wheel bolts 42 mounted on thehub unit 32 are inserted through the respectivesecond holes 38, andwheel nuts 44 are threaded over therespective wheel bolts 42, thereby integrally fastening awheel body 46 of thewheel 22 to thehat 28 and thehut unit 32. A spindle (not shown) is inserted in thehub unit 32, and aspindle nut 48 is threaded over the projecting tip end of the spindle. - As shown in FIGS. 1 through 3, the
solid disk 24 has a plurality ofcommunication holes 52 defined in ajunction 50 between thehat 28 and thedisk element 30 and providing communication between opposite first and secondsliding surfaces disk element 30. Thecommunication holes 52 are spaced at equal angular intervals around the throughhole 34 and have portions extending radially and axially of thesolid disk 24. Thecommunication holes 52 are circumferentially spaced bynarrow rims 54 of thesolid disk 24. Therims 54 function as junction members joining an inner end face of the hat 28 (the face directed inwardly of the wheel body 46) and a radially inner periphery of thedisk element 30. - Operation of the
disk brake 20 according to the first embodiment will be described below. - When a braking force is applied to the
disk element 30 of thesolid disk 24 from thebrake caliper 26 while thewheel 22 is in rotation, it reduces the speed of rotation of thesolid disk 24 and thewheel 22 which are fastened to thehub unit 32 by thewheel bolts 42 and thewheel nuts 44. - The first and second
sliding surfaces disk element 30 produce a considerable amount of heat because pads of thebrake caliper 26 are held in frictional contact with the first and second slidingsurfaces solid disk 24 is rotating, air flows radially outwardly from the center toward the outer edge of thesolid disk 24 under centrifugal forces. Specifically,first cooling air 60 flows radially outwardly along the first slidingsurface 30a of thedisk element 30, cooling the first slidingsurface 30a. - As described above, the
communication holes 52 are defined in thejunction 50 between thehat 28 and thedisk element 30 and provide communication between the first and secondsliding surfaces disk element 30. Accordingly, air flows through thecommunication holes 52 radially outwardly toward the outer edge of thesolid disk 24. Specifically,second cooling air 62 flows radially outwardly along the second slidingsurface 30b of thedisk element 30, cooling the second slidingsurface 30b. - The second sliding
surface 30b, which is positioned closely to thewheel body 46 and hence would otherwise not be exposed to much air, is therefore effectively cooled by thesecond cooling air 62, with the result that thedisk element 30 can be cooled uniformly. Since any temperature difference between the first and second slidingsurfaces solid disk 24 from being thermally deformed. Consequently, thedisk brake 20 can be prevented from producing noise or shudder. - A
disk brake 80 according to a second embodiment of the present invention will be described below with reference to FIGS. 4 through 6. Those parts of thedisk brake 80 which are identical to those of thedisk brake 20 according to the first embodiment are denoted by identical reference numerals and will not be described in detail below. - The
disk brake 80 has a ventilateddisk 82 as a disk rotor which comprises ahat 84 and adisk element 86. Thedisk element 86 comprises first and second annularcircular plates side surfaces circular plates hat 84. - As shown in FIGS. 5 and 6, the
cooling fins 92, which are in the form of a relatively thin wall, are angularly spaced at given angular intervals and extend radially. Between thecooling fins 92 and the first and second annularcircular plates cooling passages 94 which extend radially. As shown in FIGS. 4 and 5, only bases of thecooling fins 92 are present between inner circumferential edges of the first and second annularcircular plates hat 84, i.e., in the junction between thedisk element 86 and thehat 84 the fin bases function as junction members. In the junction between thedisk element 86 and thehat 84, thecooling fins 92 definetherebetween communication passages 96 which provide communication between asliding surface 88b, opposite to theside surface 88a, of the first annularcircular plate 88 and asliding surface 90b, opposite to theside surface 90a, of the second annularcircular plate 90. - In operation, the
side surfaces circular plates first cooling air 98 flowing through theradial cooling passages 94. The slidingsurface 88b of the first annularcircular plate 88 is cooled bysecond cooling air 100 which flows radially outwardly along the slidingsurface 88b.Third cooling air 102 smoothly flows through thecommunication passages 96 defined between thecooling fins 92 at the junction between thehat 84 and thedisk element 86 and along thesliding surface 90b of the second annularcircular plate 90, for thereby effectively cooling the slidingsurface 90b with thethird cooling air 102. - Therefore, the
side surfaces sliding surfaces circular plates disk element 86 in its entirety. - Since the
disk element 86 is integrally joined to thehat 84 by the coolingfins 92 which interconnect the first and second annularcircular plates disk element 86 is supported at its substantially central region by thehat 84 and hence kept in a structure which is highly resistant to thermal deformation. Thedisk element 86 is thus reliably prevented from producing noise or shudder. With the structure of the disk brake according to the present invention, as described above, inasmuch as the communication passages are defined in the junction between the hat and the disk element and provide communication between the sliding surfaces of the disk element, the sliding surfaces are reliably supplied with cooling air for uniformly cooling the disk element as a whole. - If the disk rotor comprises a solid disk, then communication holes may be defined as the communication passages in the junction between the hat and the disk element. If the disk rotor comprises a ventilated disk, then the cooling fins interconnecting the first and second annular circular plates of the disk element may be integrally joined to the hat, defining the communication passages in the junction between the cooling fins and the hat for providing communication between the sliding surfaces of the disk element through the cooling fins. Because the disk element is supported at its substantially central region by the hat through the cooling fins, the disk element is effectively prevented from being thermally deformed.
- Although certain preferred embodiments of the preinvention have been shown and described in detail, it should be understood that various changes and modificamay be made therein without departing from the scope of the appended claims.
