Description

Technical Field

[0001] This utility model relates to the field of braking device technology, and in particular to a floating brake pad and disc braking system. Background Technology

[0002] In fields such as rail transit and automobiles that require braking systems, brake pads are critical components, and their performance directly affects braking effectiveness and equipment operational safety. As the speed and load of trains and other vehicles continue to increase, higher requirements are being placed on the wear resistance of brake pads.

[0003] Current brake pads include fixed and floating types. Due to space constraints, the overall thickness must be precisely controlled within a specified range. To meet the wear thickness requirements of the brake pad particles, a thinner backing plate is needed, thus necessitating a riveted fixed brake pad structure. However, fixed brake pads are too rigid, resulting in high vibration levels during braking, causing significant damage to the brake pad particles and easily leading to particle detachment. This affects braking safety and reliability. Furthermore, the fixed contact method between the brake pad particles and the disc surface causes greater damage to the disc surface, increasing equipment maintenance costs.

[0004] Floating brake pads can adaptively adjust their pad particles according to braking pressure and vibration conditions, effectively buffering the impact force generated during braking, reducing vibration levels, and minimizing damage to the pad particles and disc surface. However, the wear thickness of current floating brake pads is limited and still cannot meet the requirements for use under high wear and forced operation conditions. Utility Model Content

[0005] This invention provides a floating brake pad and disc braking system to solve the problem that existing floating brake pads cannot meet the usage requirements under high wear and forced driving conditions.

[0006] This utility model provides a floating brake plate, comprising: A support plate has a first plate surface and a second plate surface opposite to each other in its thickness direction, and a peripheral side surface connecting the first plate surface and the second plate surface. A plurality of mounting grooves are recessed on the first plate surface, arranged along the peripheral side surface and communicating with the peripheral side surface. Multiple friction blocks are provided, and each friction block is correspondingly arranged with a mounting groove. The friction blocks are elastically connected to the support plate and partially sink into the mounting groove. A heat dissipation channel is formed between each pair of adjacent friction blocks.

[0007] According to the present invention, the shape of the mounting groove is adapted to the shape of the friction block, so that the mounting groove can restrict the rotation of the friction block relative to the support plate.

[0008] According to the present invention, a floating brake plate is provided, wherein the support plate is an arc-shaped plate, and the peripheral side has an outer ring side and an inner ring side distributed radially thereto. The plurality of mounting slots includes a plurality of first mounting slots, a plurality of second mounting slots, and two third mounting slots; the plurality of first mounting slots are arranged sequentially along the outer ring side and communicate with the outer ring side, the plurality of second mounting slots are arranged sequentially along the inner ring side and communicate with the inner ring side, and the two third mounting slots are correspondingly disposed at both ends of the arc direction of the support plate.

[0009] According to the present invention, a floating brake plate has a symmetrical central plane that is perpendicular to the first plate surface and extends radially therein. The friction part of the friction block has a hexagonal cross-sectional shape in the direction perpendicular to the first plate surface. The included angles of the six sides of the hexagon are equal. The two opposite straight sides of the hexagon are parallel to the center plane of symmetry. The plurality of first mounting slots and the plurality of second mounting slots are arranged opposite each other in the direction parallel to the center plane of symmetry.

[0010] According to the present invention, the six corners of the hexagon are all rounded, and the radius of the rounded corners of the two opposite corners of the hexagon in the extension direction of the center plane of symmetry is greater than the radius of the rounded corners of the other four corners.

[0011] According to the present invention, a floating brake plate is provided, wherein there are four first mounting slots and four second mounting slots, and the four first mounting slots, four second mounting slots and two third mounting slots are arranged symmetrically about the symmetry center plane.

[0012] According to the present invention, a floating brake pad is provided, wherein the friction block includes a fixedly connected mounting component and friction particles, the mounting component is elastically connected to the support plate and partially sinks into the mounting groove.

[0013] According to the floating brake plate provided by this utility model, it also includes: The disc spring has a mounting hole and a limiting groove surrounding the mounting hole in the mounting groove. The friction block passes through the mounting hole, and the disc spring is disposed in the limiting groove and pressed between the support plate and the friction block. A limiting member is sleeved on the friction block and located on the side of the support plate away from the mounting groove. The friction block and the limiting member are engaged in an axial upper limit fit in the mounting hole.

[0014] According to the present invention, a floating brake plate is provided, wherein the limiting member is a planar spring retainer or a non-planar spring retainer.

[0015] This utility model also provides a disc brake system, including any of the floating brake pads described above.

[0016] The floating brake pad and disc braking system provided by this utility model, by setting mounting grooves on the support plate, allows the friction block portion to sink into the mounting grooves.

In the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following related objects are in an "or" relationship.

[0031] The following is combined Figures 1-10 This invention describes a floating brake plate.

[0032] like Figures 1-2As shown, the floating brake pad provided in this embodiment of the present invention includes a support plate 1 and a plurality of friction blocks 2. The support plate 1 has a first plate surface 11 and a second plate surface 12 opposite to each other in its thickness direction, and a peripheral side surface 13 connecting the first plate surface 11 and the second plate surface 12. A plurality of mounting grooves 14 are recessed on the first plate surface 11, arranged along the peripheral side surface 13 and communicating with the peripheral side surface 13. The plurality of friction blocks 2 are arranged one-to-one with the plurality of mounting grooves 14. The friction blocks 2 are elastically connected to the support plate 1 and partially sunk into the mounting grooves 14, and a heat dissipation channel 3 is formed between each pair of adjacent friction blocks 2.

[0033] The friction block 2 of the floating brake pad is elastically connected to the support plate 1, so that the friction block 2 can automatically adjust its position during braking, ensuring that the friction block 2 is in uniform contact with the brake disc, thereby improving braking performance, reducing vibration level and extending service life.

[0034] like Figure 5 As shown, the friction block 2 includes a fixedly connected mounting member 21 and friction particles 22. The mounting member 21 is elastically connected to the support plate 1, and the friction particles 22 are fixed to the mounting member 21. The friction particles 22 can be sintered with the mounting surface of the mounting member 21 for direct contact with the brake disc. The mounting member 21 is elastically connected to the support plate 1 and serves as structural support for the friction particles 22. Typically, the shape and size of the mounting surface on the mounting member 21 for mounting the friction particles 22 are the same as or slightly wider than the outer edge of the friction particles 22. The support plate 1 is used for mounting within the brake caliper and typically matches the shape of the brake caliper jaws. For example, the support plate 1 of a disc brake pad is often arc-shaped to conform to the brake disc contour.

[0035] In this embodiment, the mounting groove 14 is arranged along and communicates with the peripheral side surface 13 of the support plate 1, allowing the friction block 2 to be as close as possible to the outer edge of the support plate 1. For example, the outer edge of any friction block 2 is tangent to the outer edge of the support plate 1, or any friction block 2 can partially extend beyond the outer edge of the support plate 1, provided the actual installation space allows. See also Figure 2 Some friction blocks have outer edges that are tangent to the outer edge of the support plate 1, and some friction blocks extend beyond the outer edge of the support plate 1.

[0036] Current braking systems have limited installation space for brake pads, and their thickness and area are strictly controlled, with the thickness needing to be below 31mm. In floating brake pad structures, the support plate 1 needs sufficient thickness to meet its support requirements, which limits the wear thickness of the friction block 2, affecting the service life of the brake pad under high wear conditions. In this embodiment, by sinking the friction block 2 into the mounting groove 14, it is possible to ensure that the wear thickness reaches 19.5mm when the brake pad thickness is 30~31mm.

[0037] The floating brake pad provided in this embodiment of the utility model, by setting an mounting groove 14 on the support plate 1, allows the friction block 2 to partially sink into the mounting groove 14. This increases the thickness of the friction block 2 while ensuring the overall thickness of the brake pad and the thickness of the support plate 1, thus increasing the wear thickness of the friction block 2 and extending its service life under high wear conditions. Multiple mounting grooves 14 are arranged along the peripheral side surface 13 of the support plate 1, and each mounting groove 14 is connected to the peripheral side surface 13 of the support plate 1. This increases the friction area of ​​each friction block 2 while ensuring that sufficient heat dissipation channels 3 are formed between each two adjacent friction blocks 2, improving the braking capacity of the friction block 2 and meeting the usage requirements under high wear and forced driving conditions. At the same time, it reduces the number of friction blocks 2 and lowers the processing cost.

[0038] In this embodiment of the invention, the shape of the mounting groove 14 is adapted to the shape of the friction block 2, so that the mounting groove 14 can restrict the rotation of the friction block 2 relative to the support plate 1. It can be understood that both the mounting groove 14 and the friction block 2 are non-circular structures, such as triangular, square, pentagonal or hexagonal, etc., so that the groove wall of the mounting groove 14 restricts the rotation and translation of the friction block 2 relative to the support plate 1.

[0039] like Figure 4 and Figure 5 As shown, the mounting groove 14 has a mounting hole 15, through which the friction block 2 passes and is elastically connected to the support plate 1 via an elastic element. Specifically, the mounting member 21 of the friction block 2 passes through the mounting hole 15 and is elastically connected to the support plate 1 via an elastic element. At least a portion of the mounting member 21 is located within the mounting groove 14, which restricts the rotation and translation of the mounting member 21 relative to the support plate 1. In this embodiment, the mounting groove 14 restricts the rotation and translation of the friction block 2, thereby improving the stability of the braking performance of the friction block 2.

[0040] like Figure 2 and Figure 3 As shown in this embodiment of the present invention, the support plate 1 is an arc-shaped plate, and its peripheral side surface 13 has an outer ring side surface 131 and an inner ring side surface 132 distributed radially therefrom. The plurality of mounting grooves 14 include a plurality of first mounting grooves 14a, a plurality of second mounting grooves 14b, and two third mounting grooves 14c. The plurality of first mounting grooves 14a are arranged sequentially along the outer ring side surface 131 and communicate with it; the plurality of second mounting grooves 14b are arranged sequentially along the inner ring side surface 132 and communicate with it; and the two third mounting grooves 14c are correspondingly disposed at both ends of the arc-shaped direction of the support plate 1.

[0041] The arc-shaped support plate 1 can be adapted to the contour of the brake disc, ensuring that the friction block 2 on the brake pad fits against the surface of the brake disc. The inner ring side 132 is closer to the center of the brake disc than the outer ring side 131. The two ends of the inner ring side 132 and the outer ring side 131 are connected to form the circumferential side 13. Both the inner ring side 132 and the outer ring side 131 may have an arc-shaped segment concentric with the brake disc.

[0042] Specifically, multiple first mounting slots 14a are arranged along the arc direction of the support plate 1 and communicate with the outer ring side 131; multiple second mounting slots 14b are arranged along the arc direction of the support plate 1 and communicate with the inner ring side 132; and two third mounting slots 14c are respectively located at both ends of the arc direction of the support plate 1, i.e., at the connection between the inner ring side 132 and the outer ring side 131. A heat dissipation channel 3 is formed between the friction blocks 2 in the multiple first mounting slots 14a and the friction blocks 2 in the multiple second mounting slots 14b. A heat dissipation channel 3 is formed between every two adjacent friction blocks 2 in the first mounting slots 14a and the friction blocks 2 in every two adjacent friction blocks 2 in the second mounting slots 14b. A heat dissipation channel 3 is formed between the friction blocks 2 in the two third mounting slots 14c and the friction blocks 2 in adjacent first mounting slots 14a and second mounting slots 14b. This fully utilizes the mounting space of the first plate surface 11 and gives the friction blocks 2 a larger friction area; the formed heat dissipation channels 3 help improve heat dissipation efficiency.

[0043] like Figure 2 As shown, in some embodiments of this utility model, the support plate 1 has a symmetrical center plane CC that is perpendicular to the first plate surface 11 and extends radially therein. The friction portion of the friction block 2 has a hexagonal cross-sectional shape in the direction perpendicular to the first plate surface 11. The included angles of the six sides of the hexagon are equal, and the two opposite straight sides of the hexagon are parallel to the symmetrical center plane CC. A plurality of first mounting grooves 14a and a plurality of second mounting grooves 14b are arranged opposite each other in a direction parallel to the symmetrical center plane CC.

[0044] The support plate 1 is an arc-shaped plate, and its radial direction is the radial direction corresponding to its arc, which is equivalent to the radial direction of the brake disc. The friction part of the friction block 2 is the friction particle 22, which is a hexagonal deformable block. See also Figure 6 The included angles of the six sides of the hexagon are equal, that is, all six angles are 120°.

[0045] A first mounting slot 14a and a second mounting slot 14b, located in a direction parallel to the center plane of symmetry CC, are defined as a slot group. Since the two opposite straight edges of the hexagon are parallel to the center plane of symmetry CC, a heat dissipation channel 3 parallel to the center plane of symmetry CC is formed between the friction blocks 2 in each adjacent slot group. Similarly, a heat dissipation channel 3 parallel to the center plane of symmetry CC is formed between the friction blocks 2 in the third mounting slot 14c and the friction blocks 2 in adjacent slot groups, thus forming multiple heat dissipation channels 3 parallel to the center plane of symmetry CC. Simulation analysis of the floating brake plate in this embodiment shows that the hexagonal friction blocks 2 and the heat dissipation channels 3 formed by their arrangement have excellent heat dissipation performance.

[0046] In this embodiment of the present invention, all six corners of the hexagonal deformation are rounded, which can avoid stress concentration in the friction particles 22 and ensure that the friction particles 22 have a large area and that there is a large distance between adjacent friction particles 22.

[0047] In some embodiments, the six corner radii of the hexagon are the same, that is, the six corner radii of the hexagonal friction particles 22 are the same.

[0048] In other embodiments, the fillet radii of two opposite corners of the hexagon in the direction of extension of the symmetry center plane CC are larger than the fillet radii of the other four corners. For example... Figure 6 As shown, the fillet radii of the two opposite corners of the hexagon along the extension direction of the symmetry center plane CC are R1, and the fillet radii of the other four corners are R2, where R1 > R2. This reduces the size of the hexagon along the extension direction of the symmetry center plane CC, i.e., reduces the size of the friction particles 22 along the extension direction of the symmetry center plane CC, forming friction particles 22 that resemble a barrel shape. Thus, the friction particles 22 can be closer to the peripheral surface 13 of the support plate 1, ensuring that the friction particles 22 have a larger friction area and that there is sufficient space between each friction particle 22 for heat dissipation, improving heat dissipation capacity and enabling rapid convection cooling during train operation.

[0049] like Figure 2 As shown, the straight edges or rounded corners of the friction particles 22 can be adjacent to the outer edge of the support plate 1, so that the friction particles 22 are as close as possible to the outer edge of the support plate 1, which is beneficial to increasing the area of ​​the friction particles 22. For the support plate 1 of commonly used specifications, by setting appropriate rounded corners for the hexagonal friction particles 22, the friction area of ​​a single friction particle 22 can reach more than 2600mm2, ensuring sufficient friction area.

[0050] See a specific example. Figure 6R1 is 25mm, R2 is 8mm, the hexagon's dimension w1 in the direction parallel to the symmetry center plane CC is 56.9mm, and its dimension w2 in the direction perpendicular to the symmetry center plane CC is 56mm. Compared to friction particles 22 with the same corner radius, simulation analysis results show that the heat dissipation channel 3 formed by the barrel-shaped friction particles 22 in this embodiment gives the gate plate better heat dissipation performance.

[0051] As a specific embodiment of this utility model, see [link to relevant documentation]. Figure 3 The number of first mounting slots 14a and second mounting slots 14b are both four. The four first mounting slots 14a, four second mounting slots 14b and two third mounting slots 14c are symmetrically arranged about the symmetry center plane CC. In this embodiment, the floating brake plate is provided with a total of ten friction blocks 2, which are symmetrically arranged about the symmetry center plane CC.

[0052] Specifically, the friction block 2 has a hexagonal cross-sectional shape in the direction perpendicular to the first plate surface 11. The included angles of the six sides of the hexagon are equal, and its two opposite straight sides are parallel to the symmetry center plane CC. Multiple first mounting slots 14a and multiple second mounting slots 14b are arranged opposite each other in a direction parallel to the symmetry center plane CC. All six corners of the hexagon are rounded, and the radius of the rounded corners of the two opposite corners extending along the symmetry center plane is larger than the radius of the rounded corners of the other four corners. The shape, quantity, and arrangement of the friction block 2 of this floating brake significantly improve its heat dissipation performance compared to existing floating brakes.

[0053] In some embodiments of this invention, the friction block 2 includes a fixedly connected mounting member 21 and friction particles 22. The mounting member 21 is elastically connected to the support plate 1 and partially recessed into the mounting groove 14. This prevents the brake disc from contacting the support plate 1 after the friction particles 22 have completely worn away, thus avoiding wear on the support plate 1.

[0054] Furthermore, such as Figure 5 and Figure 7 As shown, the mounting component 21 includes a connected mounting part 211 and a connecting shaft 212. The connecting shaft 212 passes through a mounting hole 15 in the mounting groove 14. The mounting part 211 has a hexagonal structure and is adapted to the mounting groove 14, so that the mounting groove 14 can restrict the rotation of the mounting component 21 in the mounting hole 15.

[0055] like Figure 4 and Figure 5As shown, the floating brake pad provided in this embodiment of the present invention also includes a disc spring 4 and a limiting member 5. The mounting groove 14 has a mounting hole 15 and a limiting groove 16 surrounding the mounting hole 15. The friction block 2 passes through the mounting hole 15, and the disc spring 4 is disposed within the limiting groove 16 and pressed between the support plate 1 and the friction block 2. The limiting member 5 is sleeved on the friction block 2 and located on the side of the support plate 1 away from the mounting groove 14. The friction block 2 and the limiting member 5 are axially positioned within the mounting hole 15.

[0056] Specifically, the mounting part 21 of the friction block 2 passes through the mounting hole 15, and the disc spring 4 is elastically supported between the mounting part 21 and the support plate 1 to provide shock absorption support for the friction block 2 and prevent damage to the disc due to large vibration levels during normal braking. The limiting part 5 is axially positioned and engaged with the mounting part 21 in the mounting hole 15, and the size of the limiting part 5 is larger than the size of the mounting hole 15, which can limit the mounting part 21 within the mounting hole 15 and achieve fixation of the mounting part 21.

[0057] Furthermore, such as Figure 7 As shown, the mounting component 21 has an annular groove 2111 on the side facing the support plate 1. The annular groove 2111 is opposite to the limiting groove 16 to define the mounting space for accommodating the disc spring 4. The outer ring of the mounting component 21 also has a braking contact surface 2112 surrounding the annular groove 2111. During braking, the friction block 2 is pressed down, the disc spring 4 is compressed, and the braking contact surface 2112 of the mounting component 21 is in contact with the bottom of the mounting groove 14 of the support plate 1. In this way, only the bottom of the mounting groove 14 needs to be precision machined, and the first plate surface 11 of the support plate 1 does not need to be precision machined, thus reducing production costs.

[0058] In this embodiment of the invention, the limiting member 5 is a non-planar spring retainer or a planar spring retainer. The non-planar spring retainer or planar spring retainer is formed by bending high-strength spring steel and has an arc-shaped spring segment 51 and a supporting segment 52. See also... Figure 5 and Figure 8 The connecting shaft 212 of the mounting component 21 is provided with an annular groove 2121, and the limiting component 5 is limited to the annular groove 2121.

[0059] like Figure 9 and Figure 10 As shown, the arc-shaped spring segment 51 and the abutting segment 52 of the non-planar spring retainer are not on the same plane. The arc-shaped spring segment 51 is pressed against the support plate 1, while the abutting segment 52 abuts against the mounting member 21. The non-planar spring retainer can provide the mounting member 21 with a compression spring force of more than 100N, and can interact with the disc spring 4 to fix the friction block 2.

[0060] The curved spring segment 51 and the supporting segment 52 of the planar spring retainer are on the same plane. The planar spring retainer is used for limiting and the disc spring 4 is compressed during initial installation. The disc spring 4 is used for pre-tensioning, which can provide a higher pre-tensioning force compared to non-planar spring retainers, but the processing requirements are relatively higher.

[0061] This utility model embodiment also provides a disc brake system, including the floating brake pads described in any of the above embodiments.

[0062] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
