本发明涉及轨道交通技术领域,尤其涉及一种轨道交通车辆用制动盘以及具有该制动盘的轨道交通车辆。The present invention relates to the field of rail transit technology, and in particular to a brake disc for a rail transit vehicle and a rail transit vehicle having the brake disc.
随着轨道交通的迅速发展,盘形制动因其相对于踏面制动具有摩擦性能稳定、吸收能量大、散热性能好及对踏面损坏小等优点,越来越多地运用于轨道交通车辆基础制动装置中。With the rapid development of rail transit, disc brakes are more and more used in the basic braking of rail transit vehicles because of their stable friction performance, high energy absorption, good heat dissipation performance and small damage to the tread surface. In the device.
制动盘作为盘形基础制动装置的重要组成部分,在列车制动过程通过制动闸片压紧制动盘摩擦面以实现列车制动,从而可以保证列车安全、平稳的运行,对于保证列车的安全可靠运行具有重要作用。As an important part of the disc-shaped basic brake device, the brake disc brakes the friction surface of the brake disc through the brake disc during the train braking process to realize the train braking, thus ensuring safe and stable operation of the train. The safe and reliable operation of trains plays an important role.
在制动过程中,制动盘需承受闸片施加的制动扭矩,制动盘连接件承受闸片通过盘面传递而来的制动扭矩,因此,对制动盘连接件的紧固性能及可靠性要求较高。同时,由于制动过程闸片的作用,盘体受热负荷影响会发生径向向外膨胀。During the braking process, the brake disc is subjected to the braking torque applied by the brake disc, and the brake disc connecting member receives the braking torque transmitted from the disc through the disc surface, and therefore, the fastening performance of the brake disc connecting member and Reliability requirements are high. At the same time, due to the action of the brake process brake disc, the disc body will be radially outwardly expanded due to the thermal load.
相关技术中,制动盘的盘体、隔圈与盘毂仅通过螺栓连接,一旦螺栓连接失效,则制动扭矩无法传递,螺栓将直接承受剪切力,螺栓存在被剪断风险,从而导致制动盘的可靠性降低,影响轨道交通车辆的安全性。In the related art, the disc body, the spacer ring and the hub of the brake disc are only connected by bolts. Once the bolt connection fails, the braking torque cannot be transmitted, the bolt will directly bear the shearing force, and the bolt is damaged, which leads to the system. The reliability of the moving plate is reduced, which affects the safety of rail vehicles.

下面参考附图来详细描述根据本发明实施例的轨道交通车辆用制动盘100。A brake disk 100 for a rail transit vehicle according to an embodiment of the present invention will be described in detail below with reference to the accompanying drawings.
根据本发明实施例的轨道交通车辆用制动盘100可以包括:盘体10、盘毂20、隔圈30和多个第一紧固件40。The brake disk 100 for a rail transit vehicle according to an embodiment of the present invention may include a disk body 10, a hub 20, a spacer 30, and a plurality of first fasteners 40.
如图1和图2所示,盘体10的中心设置有盘体内孔11,该盘体内孔11供盘毂20的一部分(例如盘毂本体23)穿过,盘体内孔11可以便于盘体10与盘毂20配合固定。盘体内孔11周壁上设置有多个向中心延伸的盘体连接爪12,盘体连接爪12上设置有第一盘体穿孔13,每个盘体连接爪12上可以设置有一个第一盘体穿孔13,盘体连接爪12可以起到与盘毂20配合的作用。其中,盘体连接爪12的数量不做限定,例如,盘体连接爪12的数量可以为九个。盘体连接爪12和盘体10可以为一体成型件。As shown in FIG. 1 and FIG. 2, the center of the disk body 10 is provided with a hole 11 in the disk, and the hole 11 in the disk is provided for a part of the hub 20 (for example, the hub body 23), and the hole 11 in the disk can facilitate the disk body. 10 is fixedly coupled to the hub 20. A plurality of centrally extending disk body connecting claws 12 are disposed on the peripheral wall of the inner hole 11 of the disk body. The disk body connecting claws 12 are provided with first disk body through holes 13, and each of the disk body connecting claws 12 may be provided with a first disk. The body through hole 13 and the disk connecting claw 12 can function as a cooperation with the hub 20. The number of the disk connecting claws 12 is not limited. For example, the number of the disk connecting claws 12 may be nine. The disk connecting claw 12 and the disk body 10 may be integrally formed.
如图3所示,盘毂20包括:法兰24,法兰24上设置有多个盘毂键槽21,多个盘体连接爪12与多个盘毂键槽21一一对应,每个盘体连接爪12的一部分容纳在盘毂键槽21内,每个盘毂键槽21上设置有盘毂穿孔22,每个盘毂键槽21内对应的盘毂穿孔22数量为一个。As shown in FIG. 3, the hub 20 includes a flange 24, and the flange 24 is provided with a plurality of hub key grooves 21, and the plurality of disc connecting claws 12 are in one-to-one correspondence with the plurality of hub key grooves 21, and each of the disc bodies A portion of the connecting claw 12 is housed in the hub keyway 21, and each of the hub key grooves 21 is provided with a hub through hole 22, and the number of corresponding hub through holes 22 in each of the hub key grooves 21 is one.
隔圈30位于盘体连接爪12的与盘毂键槽21相对的一侧,换言之,隔圈30和盘毂20的盘毂键槽21分别位于盘体连接爪12的两侧,隔圈30上设置有多个隔圈穿孔31。每个第一紧固件40对应穿过盘毂穿孔22、第一盘体穿孔13和隔圈穿孔31以固定盘体10、盘毂20和隔圈30。其中,第一紧固件40可以包括相互配合的螺栓和螺母,螺栓穿过盘毂穿孔22、第一盘体穿孔13和隔圈穿孔31后与螺母螺纹配合。可选地,第一紧固件40、盘毂穿孔22、第一盘体穿孔13和隔圈穿孔31的数量可以完全相同,当然也可以根据实际情况调 整。The spacer 30 is located on the side of the disk connecting claw 12 opposite to the hub key groove 21, in other words, the spacer 30 and the hub key groove 21 of the hub 20 are respectively located on both sides of the disk connecting claw 12, and are disposed on the spacer 30 There are a plurality of spacer perforations 31. Each of the first fasteners 40 correspondingly passes through the hub bore 22, the first body bore 13 and the spacer bore 31 to secure the tray 10, the hub 20 and the spacer 30. Wherein, the first fastener 40 may include bolts and nuts that cooperate with each other, and the bolts are threadedly engaged with the nut after passing through the hub through hole 22, the first disk body through hole 13 and the spacer ring through hole 31. Alternatively, the number of the first fastener 40, the hub through hole 22, the first disk body through hole 13 and the spacer ring through hole 31 may be identical, and may of course be adjusted according to actual conditions.
由此,在轨道交通车辆制动时,即制动盘100工作时,如果第一紧固件40连接失效,第一紧固件40连接形成的轴向力无法克服制动力,盘体10会产生周向转动的趋势,此时,盘体连接爪12的侧壁将会与盘毂键槽21的侧壁接触,例如,两个侧壁完全贴合,从而可将传递至盘体10的制动力传递至盘毂20上,进而可以实现在第一紧固件40失效后制动力的传递,可以使得制动盘100进行制动,可以保证制动盘100的工作可靠性。Therefore, when the rail vehicle is braking, that is, when the brake disc 100 is in operation, if the connection of the first fastener 40 fails, the axial force formed by the connection of the first fastener 40 cannot overcome the braking force, and the disc body 10 will The tendency of the circumferential rotation is generated. At this time, the side wall of the disk connecting claw 12 will come into contact with the side wall of the hub key groove 21, for example, the two side walls completely fit, so that the transfer to the disk body 10 can be performed. The power is transmitted to the hub 20, so that the transmission of the braking force after the failure of the first fastener 40 can be achieved, and the brake disc 100 can be braked to ensure the operational reliability of the brake disc 100.
需要说明的是,在第一紧固件40连接失效时,盘体连接爪12的侧壁与盘毂键槽21的侧壁接触迅速直接,制动力传递效果更好。It should be noted that when the connection of the first fastener 40 fails, the side wall of the disk connecting claw 12 is in direct contact with the side wall of the hub key groove 21, and the braking force transmission effect is better.
根据本发明的一个优选实施例,如图2和图3所示,隔圈30上可以设置有多个隔圈键槽32,盘体连接爪12的另一部分容纳在隔圈键槽32内。每个隔圈键槽32应在轴向上与每个盘毂键槽21相对应设置。由此,在第一紧固件40连接失效时,盘体10可以将制动力传递至盘毂20和隔圈30上,从而可以使得制动盘100更好地进行制动,可以提高制动盘100的工作可靠性。In accordance with a preferred embodiment of the present invention, as shown in Figures 2 and 3, a plurality of spacer keyways 32 may be provided in the spacer 30, and another portion of the tray coupling jaws 12 is received within the spacer keyway 32. Each spacer key groove 32 should be disposed in the axial direction corresponding to each of the hub key grooves 21. Thereby, when the connection of the first fastener 40 fails, the disk body 10 can transmit the braking force to the hub 20 and the spacer 30, so that the brake disk 100 can be braked better, and the brake can be improved. The operational reliability of the disc 100.
可选地,如图2所示,盘毂键槽21和隔圈键槽32的深度总和小于盘体连接爪12的厚度。换言之,盘体连接爪12的再一部分连接在盘体连接爪12的一部分和另一部分之间,该再一部分位于盘毂键槽21和隔圈键槽32的外侧。这样可以保证在制动盘100组装时,盘体连接爪12的两侧端面完全与盘毂键槽21和隔圈键槽32贴合,从而可以提高盘体10、盘毂20和隔圈30之间的固定可靠性,进而可以提高制动盘100的结构可靠性。Alternatively, as shown in FIG. 2, the sum of the depths of the hub key groove 21 and the spacer key groove 32 is smaller than the thickness of the disk connecting claw 12. In other words, a further portion of the disk connecting claw 12 is connected between a portion of the disk connecting claw 12 and another portion which is located outside the hub key groove 21 and the spacer key groove 32. This ensures that when the brake disc 100 is assembled, both end faces of the disc connecting claw 12 are completely engaged with the hub key groove 21 and the spacer key groove 32, so that the disk body 10, the hub 20 and the spacer 30 can be improved. The fixed reliability further increases the structural reliability of the brake disc 100.
另一种可选地,盘毂键槽21和隔圈键槽32的深度总和等于盘体连接爪12的厚度。这样同样可以保证盘体连接爪12的两侧端面完全与盘毂键槽21和隔圈键槽32贴合,从而可以提高盘体10、盘毂20和隔圈30之间的固定可靠性,进而可以提高制动盘100的结构可靠性。Alternatively, the sum of the depths of the hub keyway 21 and the spacer keyway 32 is equal to the thickness of the disk connecting claw 12. In this way, it is also ensured that both end faces of the disk connecting claw 12 are completely engaged with the hub key groove 21 and the spacer key groove 32, so that the fixing reliability between the disk body 10, the hub 20 and the spacer 30 can be improved, and thus The structural reliability of the brake disc 100 is improved.
具体地,如图2所示,盘毂键槽21的深度和隔圈键槽32的深度可以相同。这样盘体连接爪12容纳在盘毂键槽21的部分和容纳在隔圈键槽32的部分厚度相同,从而可以使得制动盘100整体对称性较好,进而可以提高制动盘100的结构可靠性。Specifically, as shown in FIG. 2, the depth of the hub key groove 21 and the depth of the spacer key groove 32 may be the same. Thus, the portion of the disk connecting claw 12 accommodated in the hub key groove 21 and the portion accommodated in the spacer key groove 32 have the same thickness, so that the overall symmetry of the brake disk 100 can be improved, thereby improving the structural reliability of the brake disk 100. .
盘毂键槽21的侧壁、隔圈键槽32的侧壁和盘体连接爪12的侧壁分别沿径向延伸,而且盘毂键槽21的侧壁、隔圈键槽32的侧壁和盘体连接爪12的侧壁延伸方向相同。由此,在第一紧固件40失效后,盘体连接爪12的侧壁可以同时贴靠在盘毂键槽21的侧壁和隔圈键槽32的侧壁,从而盘体10可以将制动力传递至盘毂20和隔圈30上。The side wall of the hub key groove 21, the side wall of the spacer key groove 32, and the side wall of the disk connecting claw 12 extend in the radial direction, respectively, and the side wall of the hub key groove 21, the side wall of the spacer key groove 32, and the disk body are connected. The side walls of the claws 12 extend in the same direction. Thus, after the first fastener 40 fails, the side wall of the disk connecting claw 12 can simultaneously abut against the side wall of the hub keyway 21 and the side wall of the spacer key groove 32, so that the disk body 10 can apply braking force. It is transmitted to the hub 20 and the spacer 30.
另外,在盘体10受到热负荷作用时,盘体连接爪12的径向膨胀方向与盘毂键槽21的侧壁和隔圈键槽32的侧壁的延伸方向一致,即盘体10沿着盘体连接爪12、盘毂键槽21及隔圈键槽32发生径向向外滑动,而不会与盘毂20及隔圈30发生干涉,其径向膨胀变形的 释放不受约束,从而不对盘毂20、隔圈30及螺栓等连接件产生额外的应力作用。其中,盘体10内部设置有散热结构。In addition, when the disk body 10 is subjected to a thermal load, the radial expansion direction of the disk connecting claw 12 coincides with the extending direction of the side wall of the hub keyway 21 and the side wall of the spacer key groove 32, that is, the disk body 10 is along the disk. The body connecting claw 12, the hub key groove 21 and the spacer key groove 32 slide radially outward without interfering with the hub 20 and the spacer 30, and the release of the radial expansion deformation is not restricted, so that the hub is not 20, the spacer 30 and bolts and other connectors produce additional stress. The inside of the disk body 10 is provided with a heat dissipation structure.
根据本发明的一个具体实施例,第一盘体穿孔13的位置圆直径可以小于盘毂穿孔22的位置圆直径和隔圈穿孔31的位置圆直径。换言之,第一盘体穿孔13的所在中心线位于盘毂20的盘毂穿孔22、隔圈30的隔圈穿孔31及垫片50组装后垫片穿孔所在中心线的更靠近盘体10中心一侧,这样在盘体10发生径向膨胀变形时,第一盘体穿孔13沿径向向外膨胀发生变形,从而使其在实际制动工况下的工作中心与盘毂20的盘毂穿孔22、隔圈30的隔圈穿孔31的中心更为接近,螺栓杆部与盘毂穿孔22及隔圈穿孔31之间的间隙更大,进而可以进一步保证螺栓的杆部不受剪切力作用。According to a particular embodiment of the invention, the position circle diameter of the first disk body perforation 13 may be smaller than the position circle diameter of the hub hub perforation 22 and the position circle diameter of the spacer ring hole 31. In other words, the center line of the first disk body through hole 13 is located at the hub through hole 22 of the hub 20, the spacer through hole 31 of the spacer 30, and the center line of the gasket perforation after the gasket 50 is assembled is closer to the center of the disk body 10. On the side, when the disk body 10 is radially expanded and deformed, the first disk body through hole 13 is expanded and deformed in the radial direction, so that the working center under the actual braking condition and the hub of the hub 20 are perforated. 22. The center of the spacer ring 31 of the spacer 30 is closer, and the gap between the bolt portion and the hub through hole 22 and the spacer through hole 31 is larger, thereby further ensuring that the bolt portion is not subjected to shearing force. .
可选地,第一紧固件40可以分别与对应的第一盘体穿孔13、盘毂穿孔22和隔圈穿孔31间隙配合,并通过结构设计及尺寸公差的设计可以保证第一紧固件40失效时盘体连接爪12的侧壁、盘毂键槽21的侧壁和隔圈键槽32的侧壁贴合,且螺栓的杆部与盘毂穿孔22、第一盘体穿孔13和隔圈穿孔31不接触,因此,制动力不会传递至螺栓上,螺栓的杆部在周向上不会受到剪切力作用,从而可以形成对螺栓连接的有效保护,可以提高螺栓连接的可靠性。Optionally, the first fasteners 40 can be respectively mated with the corresponding first disk body through holes 13, the hub through holes 22 and the spacer ring holes 31, and the first fastener can be ensured by structural design and dimensional tolerance design. When the 40 fails, the side wall of the disk connecting claw 12, the side wall of the hub key groove 21 and the side wall of the spacer key groove 32 are fitted, and the rod portion and the hub through hole 22, the first disk body through hole 13 and the spacer ring The perforation 31 is not in contact, and therefore, the braking force is not transmitted to the bolt, and the rod portion of the bolt is not subjected to the shearing force in the circumferential direction, so that the bolt connection can be effectively protected, and the reliability of the bolt connection can be improved.
进一步地,盘体连接爪12的侧面分别与盘毂键槽21和隔圈键槽32设置一定量的间隙配合。这样一方面可以便于组装,另一方面可以有利于盘体连接爪12的侧壁与盘毂键槽21的侧壁和隔圈键槽32的侧壁小间隙配合,可以实现盘体10与盘毂20的周向定位安装。Further, the side faces of the disk connecting claws 12 are respectively provided with a certain amount of clearance fit with the hub key groove 21 and the spacer key groove 32. In this way, the assembly can be facilitated on the one hand, and the side wall of the tray connecting claw 12 can be facilitated to have a small clearance fit with the side wall of the hub keyway 21 and the side wall of the spacer keyway 32, so that the disk body 10 and the hub 20 can be realized. The circumferential positioning is installed.
更进一步地,第一紧固件40与对应的第一盘体穿孔13、盘毂穿孔22和隔圈穿孔31之间的间隙最小值为a,盘体连接爪12分别与盘毂键槽21和隔圈键槽32之间的间隙最大值为b,a与b满足关系式:a>b。需要说明的是,间隙最小值a可以为第一紧固件40与第一盘体穿孔13之间的间隙,也可以为第一紧固件40和盘毂穿孔22之间的间隙,也可以为第一紧固件40和隔圈穿孔31之间的间隙。间隙最大值b可以为盘体连接爪12的侧壁与盘毂键槽21的侧壁之间的间隙,也可以为盘体连接爪12的侧壁和隔圈键槽32的侧壁之间的间隙。满足上述关系式的制动盘100在第一紧固件40失效后,能够保证盘体连接爪12优先与盘毂键槽21的侧壁和隔圈键槽32的侧壁贴合,这样可以更好地保证第一紧固件40的不接触和不受力。Further, the minimum value of the gap between the first fastener 40 and the corresponding first disk body through hole 13, the hub through hole 22 and the spacer ring hole 31 is a, and the disk body connecting claw 12 is respectively associated with the hub key groove 21 and The maximum gap between the spacer key grooves 32 is b, and a and b satisfy the relationship: a>b. It should be noted that the gap minimum a may be a gap between the first fastener 40 and the first disk body through hole 13 , or may be a gap between the first fastener 40 and the hub through hole 22 , or It is the gap between the first fastener 40 and the spacer perforation 31. The gap maximum value b may be a gap between the side wall of the disk connecting claw 12 and the side wall of the hub key groove 21, or may be a gap between the side wall of the disk connecting claw 12 and the side wall of the spacer key groove 32. . The brake disc 100 satisfying the above relationship can ensure that the disc connecting claw 12 preferentially fits the side wall of the hub hub 21 and the side wall of the spacer key groove 32 after the first fastener 40 fails, which is better. The first fastener 40 is guaranteed to be non-contact and unstressed.
可选地,如图3和图4所示,每个盘体连接爪12、每个盘毂键槽21和每个隔圈键槽32均呈U形。U形可以便于盘体连接爪12、盘毂键槽21和隔圈键槽32的侧壁的径向延伸,而且可以便于三者相互配合,从而可以提高制动盘100的装配效率。Alternatively, as shown in FIGS. 3 and 4, each of the disk body connecting claws 12, each of the hub key grooves 21, and each of the spacer ring grooves 32 has a U shape. The U shape can facilitate the radial extension of the side walls of the disk connecting claw 12, the hub key groove 21 and the spacer key groove 32, and can facilitate the mutual cooperation of the three, so that the assembly efficiency of the brake disk 100 can be improved.
具体地,如图3所示,盘毂20可以包括:盘毂本体23和法兰24,盘毂键槽21形成在法兰24上,盘毂本体23上设置有盘毂本体限位部,隔圈30上设置有隔圈限位部,盘毂本 体限位部与隔圈限位部相配合以进行周向及径向限位,从而实现隔圈30与盘毂20的周向及径向定位组装。可以理解的是,盘毂本体限位部与隔圈限位部可以到周向限位及径向限位作用,通过设置盘毂本体限位部与隔圈限位部,可以更好地实现隔圈30与盘毂20的定位,从而可以提高隔圈30的隔圈穿孔31与盘毂20的盘毂穿孔22的组装精度,可以提高螺栓连接的可靠性,可以保证螺栓的同轴组装。Specifically, as shown in FIG. 3, the hub 20 may include a hub body 23 and a flange 24. The hub keyway 21 is formed on the flange 24. The hub body 23 is provided with a hub body limiting portion. The ring 30 is provided with a spacer ring limiting portion, and the hub body limiting portion cooperates with the spacer ring limiting portion to perform circumferential and radial limiting, thereby achieving circumferential and radial directions of the spacer 30 and the hub 20 Positioning assembly. It can be understood that the hub body limiting portion and the spacer ring limiting portion can be extended to the circumferential limit and the radial limit, and the hub body limiting portion and the spacer ring limiting portion can be better realized. The positioning of the spacer 30 and the hub 20 can improve the assembly accuracy of the spacer through-hole 31 of the spacer 30 and the hub through-hole 22 of the hub 20, thereby improving the reliability of the bolt connection and ensuring coaxial assembly of the bolt.
例如,结合图3和图4所示,盘毂本体限位部可以构造为弧形凹槽25,隔圈限位部可以构造为凸起33,而且凸起33的内壁为弧形。弧形的凸起33和弧形凹槽25设置简单,配合可靠,能够有效实现周向和径向限位。For example, in conjunction with FIGS. 3 and 4, the hub body limiting portion can be configured as an arcuate recess 25, the spacer ring retaining portion can be configured as a projection 33, and the inner wall of the projection 33 can be curved. The curved protrusions 33 and the curved grooves 25 are simple in arrangement and reliable in cooperation, and can effectively achieve circumferential and radial limit.
具体地,如图4所示,盘毂本体限位部可以为多个,而且盘毂本体限位部的数量可以小于盘毂键槽21的数量,在径向方向上,每个盘毂本体限位部的外侧均对应有盘毂键槽21。通过合理设置盘毂本体限位部和盘毂键槽21的数量,可以使得盘毂20结构合理,整体性好。Specifically, as shown in FIG. 4, the hub body limiting portion may be plural, and the number of the hub body limiting portions may be smaller than the number of the hub hubs 21, and each hub body is limited in the radial direction. The outer side of the seat portion corresponds to the hub hub slot 21. By reasonably setting the number of the hub body limiting portion and the hub hub slot 21, the hub 20 can be made structurally sound and has good integrity.
如图5和图6所示,盘体10还包括:分体式的两个摩擦片14、盘体连接爪12和多个第二紧固件15,其中,两个摩擦片14的结构可以相同,当然,两个摩擦片14也可以根据实际情况做出局部调整。As shown in FIG. 5 and FIG. 6, the disk body 10 further includes: two friction plates 14 of the split type, a disk connecting claw 12 and a plurality of second fasteners 15, wherein the two friction plates 14 have the same structure. Of course, the two friction plates 14 can also be locally adjusted according to actual conditions.
两个摩擦片14相对设置,相对设置方向为轴向。而且多个散热结构16分别固定在两个摩擦片14之间,这样在两个摩擦片14受到热负荷作用时,多个散热结构16可以在两个摩擦片14之间提供散热,从而可以降低盘体10的温度,可以减少盘体10的膨胀,进而可以提高制动盘100的结构可靠性。可选地,摩擦片14可以为锻造成型摩擦片14,这样摩擦片14的质量更好,从而可以更好地提高制动盘100的可靠性。需要说明的是,摩擦片14还可以采取其他成型方式,例如,铸造成型、喷射成型、粉末冶金压制成型、编织成型等方式。The two friction plates 14 are oppositely disposed, and the opposite direction is the axial direction. Moreover, a plurality of heat dissipation structures 16 are respectively fixed between the two friction plates 14, so that when the two friction plates 14 are subjected to a thermal load, the plurality of heat dissipation structures 16 can provide heat dissipation between the two friction plates 14, thereby reducing the heat dissipation. The temperature of the disk body 10 can reduce the expansion of the disk body 10, thereby improving the structural reliability of the brake disk 100. Alternatively, the friction plate 14 may be a forged friction plate 14 such that the quality of the friction plate 14 is better, so that the reliability of the brake disk 100 can be better improved. It should be noted that the friction plate 14 can also adopt other forming methods, such as casting molding, spray molding, powder metallurgy pressing molding, braid molding, and the like.
两个摩擦片14上还分别设置有多个第二盘体穿孔141,多个盘体连接爪12上还设置有第三盘体穿孔121,多个第二紧固件15与多个第二盘体穿孔141和多个第三盘体穿孔121一一对应以将两个摩擦片14和多个盘体连接爪12固定。其中多个盘体连接爪12和多个第二紧固件15的数量可以根据实际情况调整。The two friction plates 14 are respectively provided with a plurality of second disk body through holes 141. The plurality of disk body connecting claws 12 are further provided with a third disk body through hole 121, a plurality of second fasteners 15 and a plurality of second portions. The disk body through hole 141 and the plurality of third disk body through holes 121 are in one-to-one correspondence to fix the two friction plates 14 and the plurality of disk body connecting claws 12. The number of the plurality of disk connecting claws 12 and the plurality of second fasteners 15 can be adjusted according to actual conditions.
也就是说,在另一些实施例中,制动盘100为分体式,分体式的制动盘100至少由两个摩擦片14、多个盘体连接爪12以及多个将摩擦片14与盘体连接爪固定连接的第二紧固件15组成。That is, in other embodiments, the brake disc 100 is a split type, and the split disc 100 is composed of at least two friction plates 14, a plurality of disc connecting claws 12, and a plurality of friction plates 14 and discs. The body connecting claw is fixedly connected to the second fastener 15 .
盘毂20上设置有多个盘毂穿孔22,多个第一紧固件40与多个第三盘体穿孔121和多个盘毂穿孔22一一对应以将多个盘体连接爪12和盘毂20固定。这样盘体连接爪12可以通过第二紧固件15和第一紧固件40分别与两个摩擦片14和盘毂20固定,从而可以将盘体10和盘毂20连接在一起,进而可以保证制动盘100的整体结构可靠性。其中,第二紧 固件15和第一紧固件40可以均包括相互配合的螺栓和螺母,但是第二紧固件15和第一紧固件40可以为不同型号的紧固件,例如,第二紧固件15的螺栓径向尺寸可以小于第一紧固件40的螺栓径向尺寸。The hub 20 is provided with a plurality of hub bores 22, and the plurality of first fasteners 40 are in one-to-one correspondence with the plurality of third tray bores 121 and the plurality of hub bores 22 to connect the plurality of tray connecting claws 12 and The hub 20 is fixed. Thus, the disk connecting claw 12 can be fixed to the two friction plates 14 and the hub 20 through the second fastener 15 and the first fastener 40, respectively, so that the disk body 10 and the hub 20 can be connected together, and thus The overall structural reliability of the brake disc 100 is ensured. Wherein, the second fastener 15 and the first fastener 40 may each include a bolt and a nut that cooperate with each other, but the second fastener 15 and the first fastener 40 may be different types of fasteners, for example, The bolt radial dimension of the second fastener 15 can be less than the bolt radial dimension of the first fastener 40.
由此,根据本发明实施例的制动盘100,盘体10由多个部件组成,而且盘体10可以拆卸,这样盘体10成型具有更广的通用性,摩擦片14可以单体铸造或锻造成型后进行组装,解决了目前制动盘的盘体只得整体铸造成型的弊端,使得能保证材料内部质量的锻造成型方式可用于该类盘体10生产,可以提升制动盘100的性能。Thus, according to the brake disc 100 of the embodiment of the present invention, the disc body 10 is composed of a plurality of components, and the disc body 10 is detachable, so that the disc body 10 is formed to have wider versatility, and the friction disc 14 can be single-cast or After the forging type is assembled, the drawbacks of the current disc body to be integrally casted are solved, so that the forging type method capable of ensuring the internal quality of the material can be used for the production of the disc body 10, and the performance of the brake disc 100 can be improved.
可选地,多个盘体连接爪12分别朝向盘体10的中心延伸,而且多个盘体连接爪12周向均匀分布。这样盘体连接爪12可以沿径向方向延伸,可以便于其与盘毂20固定,而且可以提高盘毂20和盘体10之间的可靠性。具体地,盘体连接爪12的内壁呈环形,这样可以有利于盘体连接爪12的内壁与盘毂20的外壁相止抵。Alternatively, the plurality of disk body connecting claws 12 respectively extend toward the center of the disk body 10, and the plurality of disk body connecting claws 12 are evenly distributed circumferentially. Thus, the disk connecting claw 12 can extend in the radial direction, which can facilitate its fixation with the hub 20, and can improve the reliability between the hub 20 and the disk 10. Specifically, the inner wall of the disk connecting claw 12 is annular, which is advantageous in that the inner wall of the disk connecting claw 12 is restrained from the outer wall of the hub 20.
根据本发明的一个具体实施例,如图7所示,两个摩擦片14上设置有第一限位件142散热结构16上设置有第二限位件161,第二限位件161为两个,而且两个第二限位件161在轴向上与两个摩擦片14上的第一限位件142对应配合。通过第一限位件142和第二限位件161的配合,可以提高散热结构16在两个摩擦片14之间的固定可靠性,而且可以增加散热结构16与两个摩擦片14的接触面积,从而可以进一步地提升散热结构16的散热效果。According to an embodiment of the present invention, as shown in FIG. 7 , the first limiting member 142 is disposed on the two friction plates 14 , and the second limiting member 161 is disposed on the heat dissipation structure 16 , and the second limiting member 161 is two. And the two second limiting members 161 are correspondingly matched with the first limiting members 142 on the two friction plates 14 in the axial direction. The fixing reliability of the heat dissipation structure 16 between the two friction plates 14 can be improved by the cooperation of the first limiting member 142 and the second limiting member 161, and the contact area between the heat dissipation structure 16 and the two friction plates 14 can be increased. Therefore, the heat dissipation effect of the heat dissipation structure 16 can be further improved.
可选地,第一限位件142可以为凸起和凹槽中的一个,第二限位件161可以为凸起和凹槽中的另一个,凸起和凹槽相互配合。第一限位件142可以为凸起,如图7所示,凸起可以构造为柱状,凹槽同样可以为圆柱状。凹槽和凸起设计简单,制造方便,可靠性好。Optionally, the first limiting member 142 may be one of a protrusion and a groove, and the second limiting member 161 may be the other of the protrusion and the groove, and the protrusion and the groove cooperate with each other. The first limiting member 142 may be a protrusion. As shown in FIG. 7, the protrusion may be configured in a column shape, and the groove may also be cylindrical. The grooves and projections are simple in design, easy to manufacture and reliable.
具体地,每个散热结构16呈两端带有凹槽的柱状。如图5所示,散热结构16的截面图呈H形。当然,本发明并不限于此,每个散热结构16呈两端带有凹槽的锥状。如此设置的散热结构16结构简单且可靠。Specifically, each of the heat dissipation structures 16 has a columnar shape with grooves at both ends. As shown in FIG. 5, the cross-sectional view of the heat dissipation structure 16 is H-shaped. Of course, the present invention is not limited thereto, and each of the heat dissipation structures 16 has a tapered shape with grooves at both ends. The heat dissipation structure 16 thus disposed is simple and reliable in structure.
可选地,多个散热结构16在周向和径向上间隔开分布。这样多个散热结构16可以有效且均匀地带走摩擦片14的热量,可以提升盘体10的整体散热性能。对多个散热结构16的具体布置形式不做限定,多个散热结构16可以采用规则布置的形式,当然,多个散热结构16还可以采用不规则布置的形式。Optionally, the plurality of heat dissipation structures 16 are spaced apart in the circumferential and radial directions. Thus, the plurality of heat dissipation structures 16 can effectively and uniformly remove the heat of the friction plates 14, and can improve the overall heat dissipation performance of the disk body 10. The specific arrangement of the plurality of heat dissipation structures 16 is not limited. The plurality of heat dissipation structures 16 may be in a regular arrangement. Of course, the plurality of heat dissipation structures 16 may also be in an irregular arrangement.
具体地,多个散热结构16可以组成散热结构内环组a和散热结构外环组b,散热结构内环组a的多个散热结构16之间的连线形状和散热结构外环组b的多个散热结构16之间的连线形状分别为正多边形或者圆形。如图7所示,散热结构内环组a的多个散热结构16之间的连线形状和散热结构外环组b的多个散热结构16之间的连线形状分别为正六边形。通过合理布置多个散热结构16,可以使得盘体10整体散热性能更好。Specifically, the plurality of heat dissipation structures 16 may constitute a heat dissipation structure inner ring group a and a heat dissipation structure outer ring group b, and a connection shape between the plurality of heat dissipation structures 16 of the heat dissipation structure inner ring group a and a heat dissipation structure outer ring group b The line shapes between the plurality of heat dissipation structures 16 are respectively regular polygons or circles. As shown in FIG. 7, the connection shape between the plurality of heat dissipation structures 16 of the inner ring group a of the heat dissipation structure and the connection shape between the plurality of heat dissipation structures 16 of the outer ring group b of the heat dissipation structure are respectively a regular hexagon. By properly arranging the plurality of heat dissipation structures 16, the overall heat dissipation performance of the disk body 10 can be made better.
可选地,散热结构16的高度与盘体连接爪12的高度相同。这样两个摩擦片14可以相 互平行设置,从而可以使得散热结构16、盘体连接爪12分别与两个摩擦片14固定更加可靠。Alternatively, the height of the heat dissipation structure 16 is the same as the height of the disk connecting claws 12. Thus, the two friction plates 14 can be arranged in parallel with each other, so that the heat dissipation structure 16 and the disk connecting claws 12 can be more reliably fixed to the two friction plates 14, respectively.
可选地,每个盘体连接爪12上设置有多个第一盘体穿孔13,而且多个第一盘体穿孔13在盘体连接爪12的宽度方向延伸。其中,盘体连接爪12的长度方向为制动盘100的径向方向,盘体连接爪12的宽度方向可以为与法线延伸的方向。例如,每个盘体连接爪12对应的第一盘体穿孔13的数量可以为两个,两个第一盘体穿孔13对应两个第二紧固件15,这样通过设置两个第二紧固件15,可以进一步地提高盘体10的结构可靠性。Alternatively, each of the disk connecting claws 12 is provided with a plurality of first disk body through holes 13, and a plurality of first disk body through holes 13 extend in the width direction of the disk connecting claws 12. The longitudinal direction of the disk connecting claw 12 is the radial direction of the brake disk 100, and the width direction of the disk connecting claw 12 may be a direction extending from the normal. For example, the number of the first disk body through holes 13 corresponding to each of the disk connecting claws 12 may be two, and the two first disk body through holes 13 correspond to the two second fasteners 15, so that two second tights are provided by The firmware 15 can further improve the structural reliability of the disk body 10.
另外,在盘体连接爪12、盘毂20和隔圈30连接时,采用碟形弹簧片和自锁螺母,在制动盘100的紧固件出现磨损后,通过碟形弹簧片和变形量依旧能保持紧固件可靠连接,使制动盘100装置具有可靠的防松性能。In addition, when the disk connecting claw 12, the hub 20 and the spacer 30 are connected, a disc spring piece and a self-locking nut are used, and after the fastener of the brake disk 100 is worn, the disk spring piece and the amount of deformation are passed. The fasteners are still reliably connected so that the brake disc 100 device has a reliable anti-loosening performance.
如图8-图10所示,根据本发明实施例的制动盘的隔圈30可以包括:多个弧形部34,多个弧形部34首尾依次相连形成环状,换言之,多个弧形部34可以通过首尾依次相连的方式形成隔圈30,其中,每个弧形部34的结构可以相同,这样可以降低隔圈30的制造难度,而且可以使得隔圈30装配简单。As shown in FIG. 8 to FIG. 10, the spacer 30 of the brake disc according to the embodiment of the present invention may include a plurality of curved portions 34, and the plurality of curved portions 34 are connected end to end to form a ring shape, in other words, a plurality of arcs. The shape portion 34 can form the spacer 30 by sequentially connecting the ends, wherein the structure of each of the curved portions 34 can be the same, which can reduce the manufacturing difficulty of the spacer 30, and can make the spacer 30 easy to assemble.
每个弧形部34上设置有至少一个盘毂穿孔22,盘毂穿孔22可以供第一紧固件40穿过,第一紧固件40可以穿过盘体10和盘毂20上的法兰24和弧形部34的盘毂穿孔22以将三者固定在一起。第一紧固件40可以包括相互配合的螺栓和螺母。Each of the curved portions 34 is provided with at least one hub through hole 22 through which the hub through hole 22 can pass, and the first fastener 40 can pass through the disk body 10 and the hub 20 The hub 24 and the hub bore 22 of the curved portion 34 secure the three together. The first fastener 40 can include bolts and nuts that mate with one another.
由此,根据本发明实施例的制动盘100的隔圈30区别于传统的隔圈,传统的隔圈一般为一体式结构,而本发明的隔圈30采用了分体式结构,通过多个弧形部34构成隔圈30,这样当隔圈30的任意一处损坏时,可以仅更换该损坏处所对应的弧形部34即可。例如,拆卸下该损坏处所对应的第一紧固件40,然后取下损坏的弧形部34,再更换上新的弧形部34,从而新的弧形部34与其他未损坏的弧形部34重新构成整体式的隔圈30,隔圈30仍可继续工作,从而可以降低隔圈30的更换成本和更换难度。Thus, the spacer 30 of the brake disc 100 according to the embodiment of the present invention is different from the conventional spacer. The conventional spacer is generally of a unitary structure, and the spacer 30 of the present invention adopts a split structure through a plurality of The curved portion 34 constitutes the spacer 30, so that when any one of the spacers 30 is damaged, only the curved portion 34 corresponding to the damaged portion can be replaced. For example, the first fastener 40 corresponding to the damaged portion is removed, and then the damaged curved portion 34 is removed, and the new curved portion 34 is replaced, so that the new curved portion 34 and other undamaged curved portions are formed. The portion 34 reconstitutes the integral spacer 30, and the spacer 30 can continue to operate, thereby reducing the replacement cost and replacement difficulty of the spacer 30.
另外,通过在每个弧形部34上对应设置至少一个盘毂穿孔22,这样第一紧固件40可以起到有效固定弧形部34的作用,从而可以进一步地提高隔圈30在制动盘100上的安装可靠性。In addition, by providing at least one hub through hole 22 correspondingly on each of the curved portions 34, the first fastener 40 can function to effectively fix the curved portion 34, so that the spacer 30 can be further improved in braking. Installation reliability on the disc 100.
根据本发明的一个具体实施例,如图11所示,每个弧形部34的首尾两端分别设置有配合齿35和配合槽36,一个弧形部34的首端处配合齿35与另一个弧形部36的尾端处配合槽36相互配合。通过配合齿35和配合槽36的配合,可以使得相邻弧形部34之间周向和径向可靠性较好,可以使得多个弧形部34之间能够保持整体结构,进一步地可以保证隔圈30的整体结构可靠性。According to a specific embodiment of the present invention, as shown in FIG. 11, the front end and the rear end of each curved portion 34 are respectively provided with a fitting tooth 35 and a fitting groove 36, and the front end of one curved portion 34 is fitted with the tooth 35 and the other end. The fitting grooves 36 at the trailing ends of one of the curved portions 36 cooperate with each other. By the cooperation of the fitting teeth 35 and the fitting grooves 36, the circumferential and radial reliability between the adjacent curved portions 34 can be made better, and the plurality of curved portions 34 can maintain the overall structure, which can further ensure The overall structural reliability of the spacer 30.
进一步地,如图11所示,配合齿35的高度小于配合槽36的深度以及大于等于弧形部 34厚度的三分之一。如此设置的配合齿35与配合槽36配合可靠,而且可以有利于提高配合齿35和配合槽36之间的配合效率,换言之,可以有利于提高隔圈30的装配效率。Further, as shown in Fig. 11, the height of the fitting teeth 35 is smaller than the depth of the fitting groove 36 and equal to or larger than one third of the thickness of the curved portion 34. The fitting teeth 35 thus disposed are matched with the fitting groove 36, and can be advantageously used to improve the fitting efficiency between the fitting teeth 35 and the fitting groove 36. In other words, it is advantageous to improve the assembly efficiency of the spacer 30.
还有,如图11所示,配合槽36的深度可以小于等于弧形部34厚度的二分之一。这样配合槽36的深度适宜,可以在有效保证弧形部34的结构强度的同时,还可以保证配合槽36能够有效容纳配合齿35。具体地,配合齿35从弧形部36的弧向方向向相邻的弧形部34的配合槽36延伸。Also, as shown in FIG. 11, the depth of the fitting groove 36 may be less than or equal to one-half of the thickness of the curved portion 34. Thus, the depth of the groove 36 is suitable, and the structural strength of the curved portion 34 can be effectively ensured, and the fitting groove 36 can be effectively accommodated. Specifically, the engaging teeth 35 extend from the arc direction of the curved portion 36 toward the engaging groove 36 of the adjacent curved portion 34.
可选地,如图1-图3所示,多个弧形部34关于隔圈30的中心对称布置。由此,隔圈30整体结构性较好,而且可以有利于弧形部34的装配。其中,多个弧形部34的厚度可以相同,这样可以保持隔圈30的整体平整性。Alternatively, as shown in FIGS. 1-3, the plurality of curved portions 34 are symmetrically arranged with respect to the center of the spacer 30. Thereby, the spacer 30 has a good overall structure and can facilitate the assembly of the curved portion 34. Wherein, the plurality of curved portions 34 may have the same thickness, so that the overall flatness of the spacer 30 can be maintained.
下面结合图8和图9提供一种隔圈30的具体布置形式。A specific arrangement of the spacer 30 is provided below in conjunction with FIGS. 8 and 9.
如图8和图9所示,弧形部34为两个,两个弧形部34的首尾两端分别设置有配合齿35和配合槽36,每个弧形部34上设置有三个盘毂穿孔22,而且每个弧形部34上还设置有一个凸起33,凸起33设置在位于中间的盘毂穿孔22的径向内侧。由于每个弧形部34的延伸长度较大,通过设置三个盘毂穿孔22,可以有效保证盘毂20和每个弧形部34之间的固定可靠性。而且通过在每个弧形部34上设置凸起33,可以保证盘毂20和隔圈30之间的定位效果。As shown in FIG. 8 and FIG. 9, the curved portions 34 are two, and the two ends of the two curved portions 34 are respectively provided with the fitting teeth 35 and the fitting grooves 36, and each of the curved portions 34 is provided with three hubs. The perforations 22 are provided, and each of the curved portions 34 is further provided with a projection 33 which is disposed radially inward of the intermediate hub 22 in the middle. Since the length of extension of each of the curved portions 34 is large, by providing the three hub holes 22, the fixing reliability between the hub 20 and each of the curved portions 34 can be effectively ensured. Moreover, by providing the projections 33 on each of the curved portions 34, the positioning effect between the hub 20 and the spacers 30 can be ensured.
下面结合图10提供另一种隔圈30的具体布置形式。A further arrangement of another spacer 30 is provided below in connection with FIG.
弧形部34大于等于6个,例如,如图10所示,弧形部34为六个,每个弧形部34的首尾两端分别设置有配合齿35和配合槽36,每个弧形部34上分别设置有一个盘毂穿孔22和一个凸起33,凸起33位于盘毂穿孔22的径向内侧。这样每个弧形部34对应一个盘毂穿孔22适宜,从而可以保证每个弧形部34的结构强度,以及可以保证每个弧形部34与盘毂20的法兰24之间的固定可靠性,而且通过设置一个凸起33,可以保证盘毂20和隔圈30之间的定位效果。The curved portion 34 is greater than or equal to six. For example, as shown in FIG. 10, the curved portion 34 is six, and the first and second ends of each curved portion 34 are respectively provided with matching teeth 35 and fitting grooves 36, each of which is curved. The hub 34 is provided with a hub bore 22 and a projection 33, respectively, which are located radially inward of the hub bore 22. Thus, each of the curved portions 34 is adapted to correspond to a hub bore 22, so that the structural strength of each of the curved portions 34 can be ensured, and the fixing between each of the curved portions 34 and the flange 24 of the hub 20 can be ensured. And by providing a projection 33, the positioning effect between the hub 20 and the spacer 30 can be ensured.
