[0031] In order to facilitate the understanding of the present invention, the specific embodiments of the present invention will be described in more detail below with reference to the accompanying drawings.

[0032] Unless otherwise specified or defined, the "first, second..." used in this article is merely used to distinguish names and does not represent a specific quantity or order.

[0033] Unless specifically stated or defined otherwise, the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0034] It should be noted that when a component is considered to be "fixed to" another component, it can be directly fixed to the other component or there can be a central component; when an component is considered to be "connected to" another component, it can be directly connected to the other component or there can be a central component at the same time; when an component is considered to be "installed on" another component, it can be directly installed on the other component or there can be a central component at the same time. When an component is considered to be "set on" another component, it can be directly set on the other component or there can be a central component at the same time.

[0035] In order to improve the stability and efficiency of the existing brake structure. Figures 1 to 4As shown, a brake device 100 includes: a mounting seat 1, a brake pad 2, and a limiting plate 3, wherein the mounting seat 1 has a mounting groove 11; the brake pad 2 is accommodated in the mounting groove 11; the limiting plate 3 is installed on the mounting seat 1, and the limiting plate 3 and the brake pad 2 at least partially abut against each other; wherein the limiting plate 3 has a mounting surface 31, and the brake pad 2 has a contact surface 24; the height of the mounting surface 31 is less than the height of the contact surface 24. By installing the brake pad 2 in the mounting groove 11, the mounting groove 11 limits the position of the brake pad 2 on the mounting seat 1 to achieve preliminary positioning; then the limiting plate 3 is used to fix it on the mounting seat 1, and the limiting plate 3 is used to abut against the brake pad 2, thereby further fixing the position of the brake pad 2 on the mounting seat 1 and improving the stability of the brake pad 2 on the mounting seat 1; and the mounting surface 31 of the limiting plate 3 must be lower than the height of the abutting surface 24 of the brake pad 2, so that the abutting surface 24 of the brake pad 2 can achieve braking operation on the brake wheel when it contacts the brake wheel; during installation, it is only necessary to place the brake pad 2 in the mounting groove 11, and then fix the limiting plate 3 to complete the installation. This installation method is simple and efficient, and improves the problems of poor stability and inconvenient installation of the existing brake device 100.

[0036] In addition, the installation method of this brake device 100 does not fix the brake pad 2 by drilling a hole on the brake pad 2, but uses a limit plate 3 to abut against the brake pad 2, which can avoid the risk of cracking of the brake pad 2 after the hole is drilled. Since the hole is used for the fastener 4 to pass through and fix the brake pad 2, the area of ​​the abutment surface 24 on the brake pad 2 occupied by the fastener 4 is also reduced, thereby improving the braking area, stability, and service life of the brake pad 2; when the brake pad 2 is worn to a certain extent, causing the abutment surface 24 of the brake pad 2 to be in the same plane as the installation surface 31, the severely worn brake pad 2 can also be replaced in time by removing the limit plate 3, and the replacement is also more convenient.

[0037] In order to further improve the stability of the brake pad 2 on the mounting base 1. Figure 3 and Figure 4 As shown, the direction in which the mounting groove 11 limits the brake pad 2 is the first direction X, the direction in which the limiting plate 3 abuts against the brake pad 2 is the second direction Y, and the first direction X intersects with the second direction Y. On the mounting base 1, the position of the brake pad 2 on the mounting groove 11 is fixed in two different directions, which can improve the stability of the brake pad 2 on the mounting base 1. In this embodiment, the first direction X is perpendicular to the second direction Y.

[0038] In order to further improve the stability of the brake pad 2 on the mounting base 1. Figure 3 and Figure 4As shown, the brake pad 2 has a main body 21, a first clamping block 22 and a second clamping block 23, the first clamping block 22 and the second clamping block 23 are respectively installed on both sides of the main body 21, and the mounting groove 11 has a first clamping groove 111 and a second clamping groove 112, the first clamping block 22 is clamped with the first clamping groove 111, and the second clamping block 23 is clamped with the second clamping groove 112. By clamping the first clamping block 22 with the first clamping groove 111 and the second clamping block 23 with the second clamping groove 112, the two sides of the main body 21 can be restricted to achieve the position of the brake pad 2 on the mounting seat 1 in the third direction Z. In this embodiment, the first direction X, the second direction Y, and the third direction Z can be respectively expressed as the three directions of the X axis, the Y axis, and the Z axis in the coordinate system, so as to further improve the stability of the brake pad 2 on the mounting seat 1.

[0039] In order to facilitate the processing of the first block 22 and the second block 23. Figure 3 and Figure 7 As shown, the cross section of the first clamping block 22 or the second clamping block 23 is one of a triangle, a rectangle, and a trapezoid, and the first clamping groove 111 corresponds to the shape of the first clamping block 22. The shapes of the first clamping block 22 and the second clamping block 23 are relatively simple, and there is no difficulty in processing, which can improve the production efficiency of the brake pad 2. Moreover, a simple structural shape can also be clamped with the first clamping groove 111 or the second clamping groove 112.

[0040] For the convenience of installing the brake pad 2 in the mounting groove 11. Figure 1 and Figure 2 As shown, the mounting seat 1 has an opening 13, which is connected to the mounting groove 11, and the opening 13 is for the brake pad 2 to pass through, so that the brake pad 2 is engaged with the mounting groove 11. During the installation of the brake pad 2, the brake pad 2 is inserted into the opening 13, slides into the mounting groove 11 at the opening 13, and then the limiting plate 3 is fixed at the opening 13 and abuts against the brake pad 2. This opening 13 facilitates the installation of the brake pad 2 and the installation of the limiting plate 3 at the opening 13.

[0041] In order to further improve the stability of the limit plate 3 and facilitate the installation or removal of the limit plate 3. Figure 1 , Figure 2 , Figure 4 As shown, the brake device 100 also has a fastener 4, and the limit plate 3 has a mounting hole for the fastener 4 to pass through, and the limit plate 3 is fixed to the mounting seat 1 through the fastener 4. The limit plate 3 is fixed to the mounting seat 1 through the fastener 4, and the fastener 4 improves the stability of the limit plate 3 on the mounting seat 1. Moreover, when the limit plate 3 needs to be removed, the fastener 4 only needs to be screwed out of the mounting hole, which is convenient for replacing the brake pad 2 after the limit plate 3 is removed.

[0042] In order to further improve the stability of the limiting plate 3. Figure 1 and Figure 2As shown, there are at least two fasteners 4, and the two fasteners 4 are respectively installed at the two ends of the limiting plate 3. The two ends of the limiting plate 3 are fixed by the two fasteners 4, so as to further improve the stability of the limiting plate 3.

[0043] In addition, the brake pad 2 is at least partially made of carbon fiber material. Carbon fiber material is a friction material with carbon fiber as a reinforcement material, which has the characteristics of high modulus, good thermal conductivity, and heat resistance. This material has high power absorption per unit area and light specific gravity, and is particularly suitable for the production of aircraft brake pads 2. It is also used in brake pads 2 of some high-end cars abroad. However, due to its high price, its application range is limited and its output is small. In addition to carbon fiber, graphite and carbon compounds are also used in carbon fiber friction materials.

[0044] In addition, through Figure 5 and Figure 6 It can be seen that there are multiple ways to install the brake pad 2, but during the installation of the brake pad 2, there is no need to drill holes on the brake pad 2. The multiple ways to install the brake pad 2 meet different installation requirements.

[0045] In order to avoid the brake interference of the mounting seat 1 on the brake pad 2. Figure 1 , Figure 5 , Figure 6 As shown, the mounting seat 1 has a supporting surface 12, and the height of the abutting surface 24 is higher than the height of the supporting surface 12. The height of the abutting surface 24 is higher than the height of the supporting surface 12 to avoid interference between the supporting surface 12 and the abutting surface 24; moreover, the abutting surface 24 is about one centimeter higher than the supporting surface 12, and when the thickness of the worn brake pad 2 is less than one centimeter, the supporting surface 12 will not interfere with the braking of the brake pad 2.

[0046] The utility model also provides a traction machine, comprising the above-mentioned brake device 100. The brake device 100 is applied to the traction machine to facilitate the installation of the traction machine.

[0047] When quoting drawing descriptions, new features that appear are described; in order to avoid repeated quotations of drawings resulting in less concise descriptions, features that have been described clearly will not be quoted in the drawings one by one.

[0048] The purpose of the above embodiments is to exemplarily reproduce and deduce the technical solution of the utility model, and to fully describe the technical solution, purpose and effect of the utility model. Its purpose is to make the public understand the disclosed content of the utility model more thoroughly and comprehensively, and it does not limit the protection scope of the utility model.

[0049] The above embodiments are not exhaustive enumerations based on the present invention, and there may be multiple other implementations not listed. Any replacement and improvement made without violating the concept of the present invention shall fall within the protection scope of the present invention.
