[0025] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention are described in detail below.

[0026] The following is for reference. Figure 1-Figure 2 The present invention describes a brake 100 according to an embodiment of the present invention, which can be applied to a vehicle.

[0027] Combination Figure 1 As shown, the brake 100 according to the embodiment of the present utility model may mainly include: a brake drum 10 and a connecting flange 20, wherein the brake drum 10 is provided with a first positioning part 11, and the connecting flange 20 is provided with a second positioning part 21. The first positioning part 11 and the second positioning part 21 are positioned and fitted together and welded together.

[0028] Specifically, the brake drum 10 is an important component of the vehicle's braking system. It works in conjunction with the brake pads to slow down or stop the rotating wheel through friction.

[0029] The connecting flange 20 is a standard component used to connect mechanical equipment. The common connection method of the connecting flange 20 is to achieve a tight connection between two or more parts by using bolts and gaskets.

[0030] In an embodiment of this utility model, a first positioning part 11 is provided on the brake drum 10, and a second positioning part 21 is provided on the connecting flange 20. The first positioning part 11 and the second positioning part 21 can be positioned and engaged, so that the brake drum 10 and the connecting flange 20 can be quickly aligned during installation and connection, so that the brake drum 10 and the connecting flange 20 can be quickly connected, thereby improving the production efficiency of the brake 100.

[0031] Furthermore, the first positioning part 11 and the second positioning part 21 are connected and fixed by welding. This arrangement can replace the bolt connection between the brake drum 10 and the connecting flange 20 in the prior art.

[0032] In this way, on the one hand, the connection method between the brake drum 10 and the connecting flange 20 can be simplified, the process steps can be simplified, and the production efficiency can be improved. On the other hand, the number of parts in the brake 100 can be simplified, which not only helps to reduce the weight of the brake 100 and thus helps to achieve the lightweighting of the whole vehicle, but also reduces the cost of the brake 100 parts, thereby reducing the overall vehicle production cost.

[0033] In addition, fixing the first positioning part 11 and the second positioning part 21 by welding can increase the connection reliability of the brake drum 10 and the connecting flange 20, thereby improving the structural reliability of the brake 100 and enabling the brake 100 to play a more reliable role in the whole vehicle.

[0034] Therefore, by welding the first positioning part 11 on the brake drum 10 and the second positioning part 21 on the connecting flange 20, this utility model can replace the bolt connection scheme. This not only ensures the reliability of the connection between the brake drum 10 and the connecting flange 20, but also simplifies the process and reduces the weight of the brake 100, thereby achieving low cost, high reliability and lightweight of the brake 100.

[0035] According to an embodiment of this utility model, one of the first positioning part 11 and the second positioning part 21 is an inner stop, and the other is an outer stop, with the inner and outer stops mutually abutting and positioning each other. Specifically, in an embodiment of this utility model, the positioning fit of the first positioning part 11 and the second positioning part 21 is actually a positioning fit between the inner and outer stops. The positioning fit between the inner and outer stops makes the installation operation of the brake drum 10 and the connecting flange 20 more convenient and faster, and allows for high positioning accuracy of the brake drum 10 and the connecting flange 20 during installation, thereby achieving accurate installation of the brake drum 10 and the connecting flange 20.

[0036] Combination Figure 1 and Figure 2 As shown, the brake drum 10 is provided with a mounting hole, and the connecting flange 20 has a connecting part 22. The connecting part 22 extends into the mounting hole and fits against the inner peripheral wall of the mounting hole. The portion of the brake drum 10 adjacent to the mounting hole is provided with an inner stop, and the connecting part 22 is provided with an outer stop.

[0037] Specifically, a mounting hole is provided on the brake drum 10, and the connecting flange 20 extends its connecting part 22 into the mounting hole along the axial direction. This not only allows the connecting flange 20 to be connected to the brake drum 10, but also does not interfere with the transmission of power from the braking system to the wheels.

[0038] Furthermore, an outer stop is provided on the connecting portion 22 of the connecting flange 20, and an inner stop is provided on the portion of the brake drum 10 adjacent to the mounting hole. When the connecting portion 22 extends into the mounting hole and fits against the inner circumferential wall of the mounting hole, the outer stop on the connecting flange 20 and the inner stop on the brake drum 10 cooperate with each other. This allows the connecting flange 20 and the brake drum 10 to be precisely aligned, thereby ensuring the installation accuracy of the connecting flange 20 and the brake drum 10.

[0039] Combination Figure 2As shown, a limiting block 23 is provided on the outer side of the connecting flange 20 corresponding to the connecting part 22. The limiting block 23 extends radially and is axially abutted and positioned against the portion of the brake drum 10 adjacent to the mounting hole. The portion of the brake drum 10 adjacent to the mounting hole is an inner stop, and the limiting block 23 and the connecting flange 20 form an outer stop.

[0040] Specifically, a radially extending limiting block 23 is provided on the outer side of the connecting flange 20 corresponding to the connecting part 22. When the connecting part 22 extends axially into the mounting hole and fits against the inner peripheral wall of the mounting hole, the limiting block 23 can abut against the portion of the brake drum 10 adjacent to the mounting hole in the axial direction to limit the mating position of the connecting part 22 and the inner peripheral wall of the mounting hole. This ensures that the relative position of the connecting part 22 and the mounting hole remains unchanged when installing the brake drum 10 and the connecting flange 20, so that the first positioning part 11 and the second positioning part 21 can be welded and fixed, thereby ensuring the assembly accuracy of the brake drum 10 and the connecting flange 20.

[0041] According to some embodiments of the present invention, there are multiple first positioning parts 11, which are circumferentially spaced on the brake drum 10. There are multiple second positioning parts 21, which are circumferentially spaced on the connecting flange 20. The multiple first positioning parts 11 and the multiple second positioning parts 21 correspond one-to-one.

[0042] Specifically, in the embodiments of this utility model, there can be multiple first positioning parts 11, and multiple first positioning parts 11 are arranged at intervals along the circumference of the brake drum 10. This arrangement can increase the number of positions of the connecting structures on the brake drum 10, and also make multiple connecting positions distributed at intervals in the circumference of the brake drum 10. This can make the force evenly distributed in the circumference of the brake drum 10, thereby ensuring the structural reliability of the circumferential edge of the brake drum 10.

[0043] Furthermore, there can be multiple second positioning parts 21, and the multiple second positioning parts 21 are arranged at intervals along the circumference of the connecting flange 20. This arrangement can increase the number of connection structures on the connecting flange 20, and also make multiple connection positions distributed at intervals along the circumference of the connecting flange 20. This can make the force evenly distributed along the circumference of the connecting flange 20, thereby ensuring the structural reliability of the circumferential edge of the connecting flange 20.

[0044] According to some other embodiments of the present invention, the first positioning part 11 extends circumferentially around the brake drum 10, and the second positioning part 21 extends circumferentially around the connecting flange 20, with the first positioning part 11 and the second positioning part 21 corresponding to each other in the circumferential direction.

[0045] Specifically, in some other embodiments of the present invention, the first positioning part 11 may also be provided to extend around the brake drum 10 in the circumferential direction, so that the first positioning part 11 is provided in the circumferential direction of the brake drum 10, which can improve the reliability of the first positioning part 11 on the brake drum 10 and improve the connection reliability of the first positioning part 11 and the second positioning part 21.

[0046] Furthermore, the first positioning part 11 is arranged to extend circumferentially, which makes the welding operation of the first positioning part 11 and the second positioning part 21 more convenient, thereby simplifying the welding process of the first positioning part 11 and the second positioning part 21 and improving the production efficiency of the brake 100.

[0047] In some other embodiments of the present invention, the second positioning part 21 may also be provided on the connecting flange 20 and extend around the connecting flange 20 in the circumferential direction. This can make the second positioning part 21 be provided in the circumferential direction of the connecting flange 20, thereby improving the reliability of the second positioning part 21 on the connecting flange 20 and enhancing the connection reliability of the second positioning part 21 and the second positioning part 21.

[0048] Furthermore, the second positioning part 21 is arranged to extend circumferentially, which makes the welding operation of the second positioning part 21 and the welding operation of the second positioning part 21 more convenient, thereby simplifying the welding process of the second positioning part 21 and the welding operation of the second positioning part 21 and improving the production efficiency of the brake 100.

[0049] Furthermore, the first positioning part 11 and the second positioning part 21 correspond to each other in the circumferential direction, which facilitates the alignment of the first positioning part 11 and the second positioning part 21, so as to facilitate welding operations between the first positioning part 11 and the second positioning part 21.

[0050] According to some other embodiments of the present invention, one of the first positioning part 11 and the second positioning part 21 is a positioning groove and the other is a positioning protrusion. The positioning protrusion extends into the positioning groove and is positioned and engaged with the positioning groove.

[0051] Specifically, in the embodiments of this utility model, the positioning fit of the first positioning part 11 and the second positioning part 21 is actually the positioning fit of the positioning groove and the positioning protrusion. The positioning groove has a simple structure and can be easily set on the brake drum 10. The positioning protrusion has a simple structure and can be easily set on the connecting flange 20.

[0052] It should be noted that the positioning groove can also be set on the connecting flange 20, and the positioning protrusion can also be set on the brake drum 10.

[0053] When installing the brake drum 10 and the connecting flange 20, the positioning protrusion can be inserted into the positioning groove so that the positioning protrusion and the positioning groove are positioned and matched. Then, the positioning protrusion and the positioning groove are welded and fixed to achieve the connection between the brake drum 10 and the connecting flange 20.

[0054] According to some embodiments of the present invention, the first positioning part 11 and the second positioning part 21 are fixed by welding at least one of argon arc welding and friction welding.

[0055] According to some embodiments of this utility model, the first positioning part 11 and the second positioning part 21 are fixed by argon arc welding. Specifically, argon arc welding can produce very clean, slag-free welds, which are suitable for products with high appearance requirements or for applications requiring high precision and high strength connections. By manually or automatically adjusting the current, the welding process can be precisely controlled, thereby meeting the welding requirements between the brake drum 10 and the connecting flange 20.

[0056] In addition, argon arc welding can be performed manually or automatically, adapting to different production environments and requirements. This improves the ease of welding operations for the brake drum 10 and the connecting flange 20, thereby increasing the production efficiency of the brake 100.

[0057] According to some embodiments of the present invention, the first positioning part 11 and the second positioning part 21 are fixed by friction welding. Specifically, friction welding utilizes the heat generated by the friction between the first positioning part 11 and the second positioning part 21 to bring the material of their contact surface to a plastic state, and then achieves the connection of the first positioning part 11 and the second positioning part 21 under applied pressure. This welding method does not require melting materials, nor does it require adding filler metal or using protective gas. Friction welding has a fast welding speed and a high degree of automation, which helps to improve the convenience of welding operations between the brake drum 10 and the connecting flange 20, thereby improving the production efficiency of the brake 100.

[0058] According to some embodiments of the present invention, the first positioning part 11 and the second positioning part 21 are fixed by laser welding. Specifically, laser welding is a welding technology that uses a high-energy-density laser beam as a heat source to melt the welding material and form a permanent connection. Laser welding consumes less energy, has less impact on the surrounding environment, and has a high degree of automation, which helps to improve the convenience of welding operations between the brake drum 10 and the connecting flange 20, thereby improving the production efficiency of the brake 100.

[0059] According to an embodiment of this utility model, the brake 100 can be applied in a vehicle. This utility model fixes the first positioning part 11 on the brake drum 10 and the second positioning part 21 on the connecting flange 20 by welding, which replaces the bolt connection. This not only ensures the reliability of the connection between the brake drum 10 and the connecting flange 20, but also simplifies the process and reduces the weight of the brake 100, thereby achieving low cost and high reliability of the brake 100, which in turn contributes to the lightweighting of the entire vehicle.
