Description

Technical Field

[0001] This utility model belongs to the field of brake technology, and in particular relates to a hub-type friction pad, a matching brake caliper, and an industrial brake. Background Technology

[0002] Brake calipers used in general industrial brakes consist of a caliper body and friction pads. The friction pads are composed of brake linings (non-metallic composite molded material) and a steel backing, which are joined together through processes such as bonding and curing. The steel backing has screw holes for connecting to the caliper body. When the brake linings wear beyond their required wear level, simply replacing the friction pads allows the brake caliper to continue operating.

[0003] This type of brake achieves braking by pushing the brake caliper to grip the brake shaft. However, due to the special nature of the brake pad material, it is impossible to achieve high dimensional accuracy, and there are assembly errors. This results in poor contact between the brake pad and the friction surface of the object being braked, a small contact area, uneven pad wear, local overheating, excessively rapid wear, and poor braking effect. Utility Model Content

[0004] To address the shortcomings of related technologies, this utility model provides a hub-type friction pad, a matching brake caliper, and an industrial brake. It optimizes the structure of the brake pad to make the hub-type friction pad fit the surface being braked better, resulting in better braking performance. This solves the problems of low fit between the brake pad and the friction surface of the object being braked, small contact area, and uneven pad wear.

[0005] In a first aspect, the present invention provides a hub-type friction pad, including a brake pad and a steel backing, wherein the steel backing is a flexible steel backing, and the brake pad has a segmented structure, wherein multiple independent block-shaped brake pads are arranged in a gapped array and fixed on the flexible steel backing.

[0006] The steel backing is designed as a flexible steel backing to improve its toughness. The brake pads are designed as a segmented structure, with multiple brake pads mounted on the flexible steel backing. Gaps are left between the brake pads to allow space during braking to accommodate the deformation of the brake pads and the bending of the flexible steel backing, thereby improving the overall deformation capacity of the hub friction pads.

[0007] In some embodiments, the flexible steel backing is in the form of an arc-shaped sheet, the flexible steel backing includes a convex surface and a concave surface, and the brake pad is fixed to the concave surface.

[0008] During braking, the concave side of the flexible steel back faces the object being braked, and the brake pads are placed on the concave surface, which helps to better contact the object being braked during braking, thereby improving the braking effect.

[0009] In some embodiments, the concave surface of the flexible steel backing is provided with a plurality of first mounting holes, and the plurality of independent block-shaped brake pads are provided with a plurality of second mounting holes corresponding to the positions of the plurality of first mounting holes.

[0010] The multiple second mounting holes on the brake pad correspond one-to-one with the multiple first mounting holes on the flexible steel backing, which facilitates the subsequent fixing of the brake pad to the concave surface of the flexible steel backing and improves the stability of the entire hub friction pad.

[0011] In some embodiments, the hub friction pad further includes:

[0012] A first fixing member passes through the first mounting hole and the second mounting hole and is connected to the flexible steel backing, for fixing the multiple independent block-shaped brake pads onto the flexible steel backing.

[0013] The first fastener passes through the first mounting hole and the second mounting hole, fixing multiple brake pads onto the flexible steel backing. This not only improves structural stability but also facilitates replacement of worn brake pads, making maintenance easier.

[0014] Secondly, this utility model also provides a brake caliper adapted to the above-mentioned friction pad. The brake caliper is adapted to be installed on the flexible steel backing. The brake caliper includes a central shaft, two hinge plates and an elastic clamping structure. The elastic clamping structure is installed on the central shaft through a mounting lug. The two hinge plates are hinged to the central shaft in a butterfly-wing shape to form an overall butterfly-shaped hinge structure.

[0015] During braking, the brake caliper and the hub friction pads are matched. The two hinge plates of the brake caliper rotate around the central axis to adjust the opening and closing angle to adapt to the deformation of the hub friction pads, which can improve the braking effect.

[0016] In some embodiments, a side edge is provided on both sides of the straight edge of the flexible steel backing, and a plurality of third mounting holes are provided on each side edge. A plurality of fourth mounting holes are provided on both sides of the second hinge plate corresponding to the positions of the third mounting holes.

[0017] The third and fourth mounting holes are positioned in a one-to-one correspondence to facilitate the subsequent connection of the flexible steel backing and the second hinge plate, thereby improving structural stability.

[0018] In some embodiments, the brake caliper further includes:

[0019] The second fastener passes through the third and fourth mounting holes and is connected to the hinge plate. It is used to connect the two sides of the straight edge of the flexible steel back to the two sides of the second hinge plate, and to fix the flexible steel back between the two hinge plates.

[0020] The second fastener passes through the third and fourth mounting holes to fix the flexible steel back between the two hinge plates, making the structure more stable and allowing the brake caliper to change its opening and closing angle as the hub friction pads deform, thus better adapting to the friction surface of the object being braked and improving the braking effect.

[0021] In some embodiments, the elastic clamping structure includes a clamping block and an elastic pad;

[0022] The clamping block is provided with a mounting lug to connect to the central shaft and is used to clamp the hub friction pad during braking.

[0023] The elastic pad is disposed on the surface of the clamping block, and the elastic pad contacts the convex surface of the flexible steel backing to adjust the deformation of the hub friction plate.

[0024] The elastic clamping structure can press the hub friction pads together during braking, allowing the hub friction pads to better fit the friction surface of the object being braked, thereby improving the braking effect.

[0025] In some embodiments, during braking, the hub friction pad is close to the friction surface of the object being braked, the elastic pad retracts, the hub friction pad deforms, causing the two hinge plates of the brake caliper to rotate around the central axis, and the hub friction pad is in contact with the friction surface of the object being braked.

[0026] Hub-type friction pads work in conjunction with brake calipers to better conform to the friction surfaces of the object being braked. This not only improves the fit but also extends the lifespan of the friction pads, thereby reducing manufacturing costs.

[0027] Thirdly, this utility model also provides an industrial brake, including the aforementioned hub-type friction pad and the aforementioned brake caliper.

[0028] Based on the above technical solution, in this embodiment of the invention, the hub-type friction pad and the brake caliper are connected and cooperate with each other. The deformation of the hub-type friction pad is adjusted according to the friction surface of the object being braked, and the opening and closing angle of the two hinge plates of the brake caliper is adjusted accordingly, so that the hub-type friction pad has a higher degree of contact and a better braking effect. During braking, adjusting to follow the friction surface of the object being braked allows for a more uniform fit of the brake pads, thereby extending the service life of the friction pads and reducing manufacturing and maintenance costs.

[0042] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

Therefore, a feature defined as "first," "second," or "third" may explicitly or implicitly include one or more of that feature.

[0045] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0046] As attached Figure 1 and 2 As shown, in an illustrative embodiment of the hub-type friction pad 1 of this utility model, it includes a brake pad 3 and a steel back. The steel back is a flexible steel back 2, and the brake pad 3 has a segmented structure. Multiple independent block-shaped brake pads 3 are arranged in a gapped array and fixed on the flexible steel back 2.

[0047] In the above illustrative embodiment, the steel back is configured as a flexible steel back 2 to improve the toughness of the steel back. The brake pad 3 is designed as a segmented structure, with multiple brake pads 3 respectively placed on the flexible steel back 2. Gaps are left between the brake pads 3 to allow space during braking to accommodate the deformation of the brake pads 3 and the bending of the flexible steel back 2, thereby improving the overall deformation capacity of the hub friction pad 1.

[0048] In some embodiments, the flexible steel backing 2 is in the shape of an arcuate sheet, and the flexible steel backing 2 includes a convex surface and a concave surface, with the brake pad 3 fixed on the concave surface.

[0049] During braking, the concave side of the flexible steel backing 2 faces the object being braked, and the brake pad 3 is set on the concave surface, which is conducive to better contact with the object being braked during braking, thereby improving the braking effect.

[0050] In some embodiments, the concave surface of the flexible steel backing 2 is provided with a plurality of first mounting holes 12, and a plurality of second mounting holes 13 are provided on the multiple independent block-shaped brake pads 3 corresponding to the positions of the plurality of first mounting holes 12.

[0051] The multiple second mounting holes 13 on the brake pad 3 correspond one-to-one with the multiple first mounting holes 12 on the flexible steel backing 2, which facilitates the subsequent fixing of the brake pad 3 to the concave surface of the flexible steel backing 2 and improves the stability of the entire hub friction pad 1.

[0052] In some embodiments, as shown in the appendix Figure 3 As shown, the hub-type friction plate 1 also includes:

[0053] The first fixing member 5 passes through the first mounting hole 12 and the second mounting hole 13 and is connected to the flexible steel back 2, for fixing multiple independent block-shaped brake pads 3 onto the flexible steel back 2.

[0054] The first fixing member 5 passes through the first mounting hole 12 and the second mounting hole 13 to fix multiple brake pads 3 onto the flexible steel backing 2, which not only improves the structural stability but also facilitates the replacement of the brake pads 3 after they wear out, making maintenance easier.

[0055] The flexible steel backing 2 is made of a thin, highly elastic cold-formed steel plate, which is formed by roller bending. A first mounting hole 12 is provided on the curved surface of the flexible steel backing 2 for connecting the brake pad 3.

[0056] The hub-type friction pad 1 consists of a flexible steel backing 2 and six brake pads 3. The brake pads 3 are bonded to the flexible steel backing 2 through a process of bonding, curing, and riveting. Multiple brake pads 3 are bonded to the flexible steel backing 2, with gaps in between to ensure the friction pad as a whole has a certain degree of deformability. Because deformation of the steel backing may increase the gap between the edge of the brake pad 3 and the flexible steel backing 2, affecting strength, a second mounting hole 13 is provided at the edge of the brake pad 3. The edge strength is reinforced by connection with the first fixing member 5.

[0057] Based on the above-mentioned hub-type friction plate 1, as shown in the attached figure Figure 4 and attached Figure 5 As shown, this utility model also provides a brake caliper 6 adapted to a hub-type friction pad 1. The brake caliper 6 is adapted to be installed on a flexible steel backing 2. The brake caliper 6 includes a central shaft, two hinge plates 7 and an elastic clamping structure. The elastic clamping structure is installed on the central shaft through a mounting ear. The two hinge plates 7 are hinged to the central shaft in a butterfly-wing shape to form an overall butterfly-shaped hinge structure.

[0058] During braking, the brake caliper 6 is adapted to the hub friction pad 1. The two hinge plates 7 of the brake caliper 6 rotate around the central axis to adjust the opening and closing angle to adapt to the deformation of the hub friction pad 1, thereby improving the braking effect.

[0059] Furthermore, as shown in the appendix Figure 2 As shown, a side edge is provided on each side of the straight edge of the flexible steel backing 2, and multiple third mounting holes 4 are provided on each side edge, as shown in the attached figure. Figure 6 As shown, multiple fourth mounting holes 11 are provided on both sides of the hinge plate 7 corresponding to the positions of the third mounting holes 4.

[0060] The third mounting hole 4 and the fourth mounting hole 11 are positioned in a one-to-one correspondence, which facilitates the subsequent connection of the flexible steel backing 2 and the second hinge plate 7 to improve structural stability.

[0061] A third mounting hole 4 is provided on the bend for connecting the brake caliper 6.

[0062] Furthermore, as shown in the appendix Figure 1 As shown, the brake caliper 6 also includes:

[0063] The second fastener 16 passes through the third mounting hole 4 and the fourth mounting hole 11 and is connected to the second hinge plate 7. It is used to connect the sides of the straight edge of the flexible steel back 2 to the sides of the second hinge plate 7 and fix the flexible steel back 2 between the two hinge plates 7.

[0064] The second fastener 16 passes through the third mounting hole 4 and the fourth mounting hole 11 to fix the flexible steel back 2 between the two hinge plates 7, so as to make the structure more stable and facilitate the brake caliper 6 to change the opening and closing angle with the deformation of the hub friction plate 1, better adapt to the friction surface of the braked object, and improve the braking effect.

[0065] Furthermore, as shown in the appendix Figure 7 As shown, the elastic clamping structure includes a clamping block 8 and an elastic pad 9.

[0066] The clamping block 8 is provided with a mounting lug to connect to the central shaft for clamping the hub friction pad 1 during braking.

[0067] An elastic pad 9 is disposed on the surface of the clamping block 8. The elastic pad 9 contacts the convex surface of the flexible steel back 2 and is used to adjust the deformation of the hub friction plate 1.

[0068] The elastic clamping structure can clamp the hub friction pad 1 during braking, so that the hub friction pad 1 can better fit the friction surface of the object being braked, thereby improving the braking effect.

[0069] As attached Figure 8 As shown, the clamping block 8 has screw holes, and the elastic pad 9 is connected by screws 10.

[0070] Furthermore, during braking, the hub friction pad 1 comes into close contact with the friction surface of the object being braked, the elastic pad 9 retracts, the hub friction pad 1 deforms, and drives the two hinge plates 7 of the brake caliper 6 to rotate around the central axis, so that the hub friction pad 1 comes into contact with the friction surface of the object being braked.

[0071] The hub-type friction pad 1 and the brake caliper 6 work together to allow the hub-type friction pad 1 to better conform to the friction surface of the object being braked. This not only improves the fit but also extends the service life of the friction pad, thereby reducing manufacturing costs.

[0072] Based on the above-mentioned hub-type friction pad 1 and brake caliper 6, as shown in the attached... Figure 9 As shown, this utility model also provides an industrial brake, including the above-mentioned hub friction pad 1 and the above-mentioned brake caliper 6.

[0073] The brake caliper 6 consists of a two-hinged plate 7, a clamping block 8, and a spring pad 9. After assembly, the three mounting holes of the two-hinged plate 7 and the clamping block 8 are coaxial, allowing for simultaneous installation on an industrial brake. The installation method is the same as that of the integrated brake caliper 6. (See attached...) Figure 10 As shown, the cotter pin 15 and the pin 14 are located at both ends of the central shaft. The cotter pin 15 and the pin 14 cooperate to limit the displacement of the hinge plate 7 and the elastic clamping structure on the central shaft.

[0074] When the industrial brake executes the braking command and engages the brake shaft, if the fit between the hub friction pad 1 and its mating surface is not high, the elastic pad 9 will retract under force, causing the hub friction pad 1 to actively deform under the braking force and fit against the mating surface. Meanwhile, the hinge plate 7 will rotate according to the deformation of the hub friction pad 1, adjusting the opening and closing angle and automatically adapting to the deformed position of the hub friction pad 1, providing braking thrust on both sides of the hub friction pad 1.

[0075] The hub-type friction pad 1, in conjunction with the hinged brake caliper 6, can effectively improve the fit between the brake pad 3 and its mating surface, which not only effectively extends the service life of the friction pad but also reduces the manufacturing cost of the friction pad.

[0076] Through the description of several embodiments of the hub-type friction pad, matching brake caliper, and industrial brake of this utility model, it can be seen that the embodiments of the hub-type friction pad, matching brake caliper, and industrial brake of this utility model have at least one or more of the following advantages:

[0077] 1. The brake pads are designed as a segmented structure, with multiple brake pads mounted on a flexible steel backing. Gaps are left between the brake pads to allow space during braking to accommodate the deformation of the brake pads and the bending of the flexible steel backing, thereby improving the overall deformation capacity of the hub friction pads.

[0078] 2. The hub-type friction pads and brake calipers work together to ensure better contact between the friction pads and the friction surface of the object being braked. This not only improves the fit but also extends the service life of the friction pads, thereby reducing manufacturing costs.

[0079] Finally, it should be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0080] The above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
