Description

Technical Field

[0001] This utility model relates to the field of motorcycle muffler technology, and in particular to an installation component for a motorcycle muffler and a motorcycle. Background Technology

[0002] There are generally two methods for mounting motorcycle mufflers at the rear mounting point. The first method involves directly fixing the muffler to the frame with bolts. Typically, the frame has threads for this connection. However, if these threads are damaged, they need to be repaired with a tap. Tap-repaired threads are prone to loosening and it's difficult to resolve accumulated tolerances. Alternatively, the frame may need to be replaced, but this method is costly. The second method involves mounting holes on the frame, where the muffler is directly fixed using bolts and nuts. However, this method requires the operator to support the nuts, bolts, and muffler while simultaneously using a tightening tool, resulting in a complex and inefficient assembly process that is also difficult to resolve accumulated tolerances.

[0003] Therefore, how to conveniently and quickly install the muffler onto the vehicle frame and facilitate maintenance is a technical problem that urgently needs to be solved in the existing technology. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a mounting component for a motorcycle muffler and a motorcycle, which can conveniently and quickly install the muffler onto the frame and facilitate maintenance.

[0005] The present invention relates to a mounting assembly for a motorcycle muffler, comprising a mounting bracket, which is detachably mounted on a support lug fixed to the motorcycle frame and has a mounting position for detachably mounting the muffler.

[0006] The side of the mounting bracket furthest from the mounting position is detachably mounted to the support ear via a bracket bolt pair, while the side closest to the mounting position is limited downward by the support ear.

[0007] Furthermore, a limiting claw extends from the mounting bracket, and the limiting claw bends toward the support ear to form a limiting part I, which rests on the support ear and is limited downward.

[0008] Furthermore, the limiting part I is bent downward to form a locking part, which is engaged on the other side of the support ear.

[0009] Furthermore, the muffler is mounted to the mounting position via a muffler bolt assembly, and the mounting position is provided with a limiting part II for placing and restricting the rotation of the nut of the muffler bolt assembly.

[0010] Furthermore, the mounting position is provided with a limiting hole for embedding and restricting the rotation of the nut of the muffler bolt assembly, and the limiting hole forms the limiting part II.

[0011] Furthermore, the mounting bracket is a sheet-like structure, including a first mounting surface and a second mounting surface. The first mounting surface is attached to the support ear and detachably fixed. The mounting position is located on the second mounting surface, and the nut of the bracket bolt pair is fixedly disposed on the first mounting surface.

[0012] Furthermore, the second mounting surface deforms relative to the first mounting surface and forms a gap with the support ear. The width of the gap is not greater than the height of the nut of the muffler bolt assembly, and the flange face of the nut of the muffler bolt assembly is located within the gap.

[0013] Furthermore, the limiting hole is a hexagonal hole, the size of which is larger than the size of the nut body of the muffler bolt assembly, and the size of which is smaller than the size of the flange face of the muffler bolt assembly nut.

[0014] The motorcycle of this invention includes the aforementioned mounting components for motorcycles.

[0015] The beneficial effects of this utility model are as follows: The installation component for a motorcycle muffler and the motorcycle of this utility model are provided. The installation bracket is set to install the motorcycle muffler onto the motorcycle frame. Compared with the existing technology of opening threaded holes on the frame, it is convenient for subsequent maintenance and use, and can reduce maintenance and replacement costs. When the muffler is fixed to the motorcycle frame by the installation bracket, the support ears can limit the installation bracket. Therefore, during assembly, the assembler only needs to hold the muffler and tightening tools to complete the installation of the muffler, which can reduce assembly steps and greatly improve assembly efficiency.

[0023] Figure 1 This is a schematic diagram of the structure of this utility model. Figure 2 for Figure 1 A magnified view of a portion of the image. Figure 3 This is a schematic diagram showing the structure when the mounting bracket and the nut of the muffler bolt pair are engaged. Figure 4 for Figure 3 Another structural diagram, such as Figure 1-4 As shown: The mounting assembly for a motorcycle muffler in this embodiment includes a mounting bracket 2, which is detachably mounted on a support lug 3 fixed to the motorcycle frame 1, and has a mounting position for detachably mounting the muffler; as shown Figure 1 As shown, the mounting bracket 2 is detachably fixed to the support ear 3 by means of bolts and nuts. The mounting bracket 2 is also provided with a mounting position for mounting the muffler, which makes it easy to install the muffler to the motorcycle frame 1. Compared with the existing technology of directly installing the muffler to the motorcycle frame 1, it is easier to maintain the muffler in the later stage and can reduce maintenance costs.

[0024] The mounting bracket 2 is detachably mounted to the support ear 3 on the side away from the mounting position via bracket bolts, while the side closer to the mounting position is limited downward by the support ear 3. The support ear 3 is generally a groove-shaped structure and is fixedly connected to the motorcycle frame 1. In use, it is used to mount the mounting bracket 2 and the engine. The mounting bracket 2 is fixedly connected to one side wall of the groove-shaped structure, and the mounting lug on the engine is fixedly connected to the other side wall of the groove-shaped structure. Thus, the support ear 3 can fix the rear end of the engine while simultaneously fixing the muffler. The overall structure is compact, saving installation space and reducing production costs.

[0025] Specifically, the support ear 3 is provided with mounting holes that mate with the bracket bolt pair. When the mounting bracket 2 is placed on the support ear 3, the side of the mounting bracket 2 closest to the mounting position can be limited downward by the support ear 3 (relative to the vertical direction of the motorcycle), so that the mounting bracket 2 cannot rotate downward. This makes it easy for the user to use a tightening tool to connect the bolt 203 of the bracket bolt pair with the nut 204 of the bracket bolt pair, thereby completing the fixed connection between the mounting bracket 2 and the support ear 3.

[0026] In this embodiment, a limiting claw extends from the mounting bracket 2, and the limiting claw bends towards the support ear 3 to form a limiting part I202, which rests on the support ear 3 and is limited downward. When the mounting bracket 2 is placed on the support ear 3, the limiting part I202 rests on the support ear 3 and is limited, so that the support ear 3 can support the mounting bracket 2 while restricting the downward rotation of the mounting bracket 2. The user does not need to additionally limit the mounting bracket 2 during assembly, which helps to save assembly steps and improve assembly efficiency.

[0027] In this embodiment, the limiting part I 202 is bent downward to form a locking part 205, which engages on the other side of the support ear 3. The limiting part I 202 is bent downward (relative to the vertical direction of the motorcycle) to form the locking part 205, as shown below. Figure 2 As shown, a support protrusion is provided on the support ear 3 at the position corresponding to the limiting part, so that the limiting part I 202 can rest on the support protrusion, and the engaging part 205 can engage with the outside of the support protrusion (relative to the inside and outside direction of the motorcycle), thereby also limiting the mounting bracket 2 in the left and right direction relative to the motorcycle.

[0028] In this embodiment, the muffler is installed at the mounting position via a muffler bolt assembly. The mounting position is provided with a limiting part II that places and restricts the rotation of the nut 201 of the muffler bolt assembly. During assembly, the muffler is detachably fixed to the mounting position via the muffler bolt assembly, thus facilitating the disassembly and installation of the muffler. After the nut 201 of the muffler bolt assembly is placed at the mounting position, the nut 201 of the muffler bolt assembly can slide relative to the front-rear direction of the motorcycle, thereby reducing the accuracy requirements for the dimensions of the motorcycle frame 1 and the muffler during assembly, reducing assembly difficulty. Furthermore, the mounting position provides a rotation limit for the nut 201 of the muffler bolt assembly. When assembling the muffler at the mounting position, the assembler does not need to fix the nut 201 of the muffler bolt assembly, saving assembly steps, shortening assembly time, and facilitating operation by the assembler.

[0029] In this embodiment, the mounting position is provided with a limiting hole 206 for embedding and restricting the rotation of the nut 201 of the muffler bolt assembly. The limiting hole 206 forms the limiting part II. The size of the limiting hole 206 is slightly larger than the size of the nut 201 of the muffler bolt assembly, so that when the nut 201 of the muffler bolt assembly is placed in the limiting hole 206, it can slide relative to the front-rear direction of the motorcycle within the limiting hole 206.

[0030] In this embodiment, the mounting bracket 2 is a sheet-like structure, including a first mounting surface and a second mounting surface. The first mounting surface is attached to and detachably fixed to the support ear 3. The mounting position is located on the second mounting surface. The nut 204 of the bracket bolt pair is fixedly disposed on the first mounting surface. The first mounting surface is attached to one side wall of the support ear 3, and one end is bent inward (relative to the inside-outside direction of the motorcycle) and forward (relative to the front-back direction of the motorcycle) to form the second mounting surface, thereby creating a gap between the second mounting surface and the support ear 3.

[0031] In this embodiment, the second mounting surface deforms relative to the first mounting surface and forms a gap with the support ear 3. The width of the gap is not greater than the height of the nut 201 of the muffler bolt assembly, and the flange face of the nut 201 of the muffler bolt assembly is located within the gap. The width of the gap (its length in the left-right direction of the motorcycle) is not greater than the height of the nut 201 of the muffler bolt assembly (its length relative to the left-right direction of the motorcycle). Figure 4 As shown, the flange face of the nut 201 of the muffler bolt assembly is located within this gap.

[0032] In this embodiment, the limiting hole 206 is a hexagonal hole. The size of the limiting hole 206 is larger than the size of the nut body of the nut 201 of the muffler bolt assembly, and the size of the limiting hole 206 is smaller than the size of the flange face of the nut 201 of the muffler bolt assembly. The nut 201 of the muffler bolt assembly is a hexagonal flange nut, such as... Figure 3 As shown, the size of the limiting hole 206 is larger than the size of the nut body of the nut 201 of the muffler bolt assembly. The length of the limiting hole 206 relative to the front-rear direction of the motorcycle can be set according to actual needs, such as designing it based on the maximum cumulative range of dimensional tolerances of the muffler, engine, support ear 3, etc. at this location. This can reduce the dimensional accuracy requirements of the muffler and frame 1, and reduce assembly difficulty. At the same time, since the flange face of the nut 201 of the muffler bolt assembly is located within the gap and the flange face size of the nut 201 of the muffler bolt assembly is larger than the size of the limiting hole 206 (e.g., Figure 4 As shown), this allows the nut 201 of the muffler bolt assembly to slide back and forth along the limiting hole 206 (relative to the front and rear direction of the motorcycle) while preventing the nut 201 of the muffler bolt assembly from coming out of the limiting hole 206.

[0033] The motorcycle of this embodiment includes the aforementioned mounting assembly for the motorcycle muffler.
