Description

Technical Field

[0001] This application relates to the field of vehicle frames, and more particularly to a motorcycle frame. Background Technology

[0002] As the core of the motorcycle's structure and support, the motorcycle frame bears the heavy responsibility of connecting key components such as the engine, suspension system, passengers, and luggage. Its design must take into account factors such as strength, rigidity, lightweighting, and cost.

[0003] The engine is directly bolted to the frame. The vibration generated during engine operation is directly transmitted to the frame. The connection point between the frame and the engine breaks due to stress concentration, requiring the entire frame to be replaced. This shortens the service life of the motorcycle frame and increases the user's operating costs. Summary of the Invention

[0004] In order to improve the cost of using motorcycles, this application provides a motorcycle frame.

[0005] This application provides a motorcycle frame, which adopts the following technical solution: A motorcycle frame includes a frame body, an engine, and a fixing assembly. The fixing assembly includes a suspension bracket, multiple elastic sleeves, and multiple fixing bolts. The inner wall of the frame body has multiple threaded holes (I) spaced apart for the fixing bolts to pass through. The surface of the suspension bracket facing the frame body has multiple threaded holes (II) for the fixing bolts to be threaded and tightened. The elastic sleeves are embedded in the threaded holes (II) one by one, and the inner cavity of the elastic sleeves is for the fixing bolts to pass through. The surface of the suspension bracket and the surface of the frame body clamp the two sides of the elastic sleeves to form a fixation. The surface of the engine body has multiple threaded holes (III) spaced apart for the fixing bolts to be threaded and tightened. The surface of the suspension bracket facing the engine has multiple threaded holes (IV) for the fixing bolts to pass through. The fixing bolts are threaded through the threaded holes (IV) one by one and tightened into the inner wall of the threaded holes (III) to form a fixation.

[0006] By adopting the above technical solution, during frame assembly, the suspension bracket is placed between the frame and the engine. Threaded holes one and two correspond one-to-one and are connected. The ends of the fixing bolts correspond one-to-one and pass through threaded holes one and the inner cavity of the elastic sleeve. The surface of the suspension bracket and the surface of the frame clamp the two sides of the elastic sleeve to form a fixation. Simultaneously, threaded holes three and four correspond one-to-one and are connected. The ends of the fixing bolts pass through threaded hole four and are threaded and tightened to fix the engine to the inner wall of threaded hole three, thus achieving the installation between the engine and the suspension bracket. When the motorcycle is running, the vibration generated by the engine starting is transmitted to the suspension bracket. The elastic sleeve is clamped and fixed between the suspension bracket and the frame. With a certain degree of elasticity, the elastic sleeve can absorb and attenuate the vibration transmitted by the suspension bracket, ensuring that the suspension bracket does not easily transmit vibration directly to the frame, reducing fatigue cracks at the frame connection points caused by long-term high-load vibration, lowering the risk of frame breakage, thereby extending the service life of the motorcycle frame and reducing the operating cost of the motorcycle frame; when the connection between the suspension bracket and the engine is damaged and needs to be replaced, the fixing bolts are loosened to separate the suspension bracket from the frame, only the suspension bracket and engine need to be replaced, without replacing the entire frame, reducing material waste, thus reflecting the concept of energy saving and further reducing the operating cost of the motorcycle frame.

[0007] Optionally, two suspension brackets are provided, and the two suspension brackets are connected one-to-one to both ends of the engine.

[0008] By adopting the above technical solution, two suspension brackets are connected one-to-one to both ends of the engine, increasing the connection points between the engine and the frame, thereby improving the connection stability between the engine and the frame.

[0009] Optionally, the frame is connected to a limiting component, which includes multiple abutment rings. The multiple abutment rings are connected at intervals to the inner wall of the frame. Each abutment ring corresponds to a threaded hole. The axis of the abutment ring coincides with the axis of the threaded hole, and the inner ring of the abutment ring can abut against the outer circumferential surface of the fixing bolt to form a seal.

[0010] By adopting the above technical solution, when the end of the fixing bolt passes through the threaded hole and is screwed into the inner wall of the threaded hole, the inner ring wall of the abutting ring abuts against the outer circumference of the fixing bolt to form a seal, making it difficult for outside air to enter the abutting point between the fixing bolt and the inner wall of the threaded hole and corrode the fixing bolt, thereby improving the connection stability between the suspension bracket and the frame.

[0011] Optionally, the limiting component further includes multiple sealing rings, which are spaced apart and connected to the inner wall of the frame. Each sealing ring corresponds to a clamping ring bladder, and the axis of the sealing ring coincides with the axis of the clamping ring bladder. The inner wall of the sealing ring and the outer circumferential surface of the fixing bolt abut against both sides of the clamping ring bladder to form a seal.

[0012] By adopting the above technical solution, when the end of the fixing bolt passes through the threaded hole and is screwed into the inner wall of the threaded hole, the inner wall of the sealing ring and the outer circumferential surface of the fixing bolt abut against both sides of the sealing ring bladder to form a seal, ensuring the abutting force between the inner wall of the sealing ring bladder and the outer circumferential surface of the fixing bolt, thereby improving the sealing stability between the inner wall of the sealing ring bladder and the outer circumferential surface of the fixing bolt.

[0013] Optionally, the limiting assembly further includes multiple limiting plates, which are slidably connected to the inner wall of the frame at intervals. Each limiting plate corresponds to a threaded hole, and the sliding direction of the limiting plate is perpendicular to the axis of the threaded hole. The limiting plate has a limiting cavity for the sealing ring to be embedded in. When the limiting plate slides towards the threaded hole, the inner wall of the limiting cavity abuts against the end face of the fixing bolt to form a limit.

[0014] By adopting the above technical solution, when the limiting plate slides towards the threaded hole one, the sealing ring is embedded in the limiting cavity, and the inner wall of the limiting cavity abuts against the end face of the fixing bolt to form a limit, so that the fixing bolt is not easy to shift in the inner wall of the threaded hole one, thereby improving the connection stability between the suspension bracket and the frame.

[0015] Optionally, the limiting plate includes a sliding part, a limiting part, and a rod part. The sliding part slides on the inner wall of the frame. The limiting cavity is located on the sliding part. The inner wall of the limiting cavity facing the fixing bolt has a sliding hole for the rod part to slide. The limiting part is connected to the end face of the rod part facing the fixing bolt. A limiting ring is connected to the surface of the limiting part facing the sealing ring. A limiting groove is formed on the surface of the sealing ring for the limiting ring to be inserted. When the sliding part approaches the sealing ring and the sealing ring is inserted into the limiting cavity, the rod part is driven to slide along the inner wall of the sliding hole towards the fixing bolt. The limiting ring is inserted into the limiting groove to form a limit, and the surface of the limiting part abuts against the end face of the fixing bolt to form a limit.

[0016] By adopting the above technical solution, when the sliding part slides towards the sealing ring and the sealing ring is embedded in the limiting cavity, the limiting ring faces the limiting groove, driving the rod part to slide along the inner wall of the sliding hole towards the fixing bolt. The limiting ring is embedded in the limiting groove to form a limit, and the surface of the limiting part abuts against the end face of the fixing bolt to form a limit, making it difficult for the limiting plate to deviate from the inner wall of the sliding groove, thereby improving the limiting stability of the limiting plate in the suspension bracket.

[0017] Optionally, the limiting assembly further includes a plurality of elastic elements. One end of each elastic element is connected to the end of the rod away from the limiting part in the elastic direction, and the other end of each elastic element is connected to the surface of the sliding part. Each elastic element has the elastic force to drive the rod to slide towards the fixing bolt, and the surface of the limiting part abuts against the end face of the fixing bolt to form a limiting position.

[0018] By adopting the above technical solution, before the sliding part approaches the sealing ring, the rod is driven to slide along the inner wall of the sliding hole away from the suspension bracket. The end face of the limiting ring is flush with the end face of the sealing ring. The sliding part is driven to slide along the suspension bracket towards the sealing ring. The limiting ring faces the limiting groove. The rod is released, and the elastic element drives the rod to slide along the inner wall of the sliding hole towards the fixing bolt. The limiting ring is embedded in the limiting groove, and the surface of the limiting part abuts against the end face of the fixing bolt to form a limit, so that the rod is not easy to deviate in the inner wall of the sliding hole, thereby improving the stability of the abutment between the surface of the limiting part and the end face of the fixing bolt.

[0019] Optionally, the sliding part is connected to a slider on the surface of the frame, and the surface of the frame is provided with a slide rail for the slider to slide.

[0020] By adopting the above technical solution, when the slider slides on the inner wall of the slide, it drives the sliding part to slide on the surface of the frame, making it less likely for the sliding part to deviate on the surface of the frame, thereby improving the stability of the sliding part sliding on the surface of the frame.

[0021] Optionally, an inflation assembly is connected between the slider and the frame. The inflation assembly includes a magnetic block one, a magnetic block two, and an inflation piston. An inflation channel is provided in the frame for the inflation piston to slide. The sliding direction of the inflation piston and the sliding direction of the slider are parallel to each other. The inflation channel connects to the inner cavity of the pressure ring bladder. The magnetic block one is connected to the surface of the inflation piston facing the slider, and the magnetic block two is connected to the surface of the slider facing the magnetic block one. The magnetic blocks one and two are attracted to each other by opposite poles. When the slider slides on the inner wall of the channel, it drives the inflation piston to slide on the inner wall of the inflation channel, which in turn drives the air in the inflation channel into the inner cavity of the pressure ring bladder.

[0022] By adopting the above technical solution, magnetic block one and magnetic block two attract each other with opposite poles. When the slider is driven to slide along the inner wall of the slideway toward the direction of the sealing ring, the inflation piston is driven to slide along the inflation channel toward the direction of the pressing ring bladder. The air pressure in the inflation channel increases, and the air in the inflation channel enters the inner cavity of the pressing ring bladder. The inner wall of the pressing ring bladder is pressurized and expanded and presses against the outer circumference of the fixing bolt to form a limit.

[0023] Optionally, the frame is connected to an induction assembly, which includes an induction piston, a power piston, and an elastic element two. A power flow channel for the power piston to slide is formed on the surface of the frame facing the fixing bolt. The sliding direction of the power piston is parallel to the axis of the threaded hole one. One end of the elastic element two, in the direction of its elastic force, is connected to the surface of the power piston, and the other end is connected to the inner wall of the power flow channel. The elastic element two has the elastic force to drive the power piston to slide away from the suspension bracket, and the end of the power piston tends to protrude from the surface of the frame. An induction flow channel for the induction piston to slide is formed on the surface of the frame. The sliding direction of the induction piston is parallel to the sliding direction of the power piston. The induction flow channel connects to the power flow channel. When the end of the fixing bolt passes through the threaded hole one and is threaded and tightened to the inner wall of the threaded hole two, the end face of the fixing bolt abuts against the power piston and drives the power piston closer to the frame, and the surface of the induction piston is flush with the surface of the frame.

[0024] By adopting the above technical solution, when the end of the fixing bolt passes through the threaded hole and is screwed into the inner wall of the threaded hole, the end face of the fixing bolt abuts against the end face of the power piston and drives the power piston to slide towards the frame. The end face of the power piston is flush with the surface of the frame. At the same time, the power flow channel is connected to the starting flow channel. The air in the power flow channel enters the starting flow channel, driving the starter piston to slide away from the frame. The surface of the starter piston is flush with the surface of the frame. This allows the workers to directly judge the tightening of the fixing bolt based on the depth of the starter piston in the inner wall of the starter flow channel, thereby improving the installation efficiency of the motorcycle frame.

[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. The suspension bracket, elastic sleeve, and fixing bolts are designed so that the suspension bracket can be separated from the frame by unscrewing the fixing bolts. Only the suspension bracket and engine need to be replaced, without replacing the entire frame, which reduces material waste and embodies the concept of energy saving, further reducing the cost of using the motorcycle frame. 2. The setting of the clamping ring bladder, the inner wall of the clamping ring bladder abuts against the outer circumference of the fixing bolt to form a seal, so that the outside air is not easy to enter the clamping point between the fixing bolt and the inner wall of the threaded hole and corrode the fixing bolt, thereby improving the connection stability between the suspension bracket and the frame. 3. The sealing ring is designed so that the inner wall of the sealing ring and the outer circumference of the fixing bolt abut against both sides of the sealing ring bladder to form a seal, ensuring the clamping force between the inner wall of the sealing ring bladder and the outer circumference of the fixing bolt, thereby improving the sealing stability between the inner wall of the sealing ring bladder and the outer circumference of the fixing bolt.

Detailed Implementation

[0032] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0033] This application discloses a motorcycle frame. (Refer to...) Figure 1 A motorcycle frame includes a frame body 1, an engine 2, and a fixing component 3. The fixing component 3 is connected between the frame body 1 and the engine 2. The fixing component 3 is detachably connected between the frame body 1 and the engine 2. When the connection between the engine 2 and the fixing component 3 is damaged and needs to be replaced, only the fixing component 3 and the engine 2 need to be removed for replacement, without having to replace the entire frame body 1. This reduces material consumption, embodies the concept of energy saving, and further reduces the cost of using the motorcycle frame.

[0034] Reference Figure 2 and Figure 3The fixing component 3 includes a suspension bracket 31, multiple elastic sleeves 32, and multiple fixing bolts 33. Multiple threaded holes 11 for the fixing bolts 33 to pass through are spaced apart on the inner walls of both sides of the frame 1 in the width direction. Multiple threaded holes 311 for the fixing bolts 33 to be threaded are correspondingly opened at both ends of the suspension bracket 31 in the length direction. The elastic sleeves 32 can be made of rubber or silicone. In this embodiment, the elastic sleeves 32 are made of rubber, which has a certain deformation capacity. The elastic sleeves 32 correspond one-to-one with the threaded holes 311. One end of the elastic sleeve 32 is coaxially embedded in the threaded hole 311, and the other end of the elastic sleeve 32 protrudes from the surface of the suspension bracket 31. The inner cavity of the elastic sleeve 32 allows the fixing bolts 33 to pass through. When the ends of the fixing bolts 33 pass through the threaded holes 11 and the inner cavity of the elastic sleeve 32, the surface of the suspension bracket 31 and the surface of the frame 1 clamp the two sides of the elastic sleeve 32 to form a fixation, realizing a detachable elastic connection between the suspension bracket 31 and the frame 1.

[0035] Reference Figure 2 and Figure 3 The engine 2 has multiple threaded holes 21 spaced apart on its surface for tightening the fixing bolts 33. The suspension bracket 31 has multiple threaded holes 312 on its surface facing the engine 2 for the fixing bolts 33 to pass through. The fixing bolts 33 pass through the corresponding threaded holes 312 and are tightened to the inner wall of the threaded holes 21, forming a fixed connection and achieving a detachable connection between the engine 2 and the suspension. When the motorcycle is running, the vibration generated by the engine 2 is transmitted to the suspension bracket 31. An elastic sleeve 32 is clamped and fixed between the suspension and the frame 1. The elastic sleeve 32 has a certain deformation capacity and can absorb... The suspension bracket 31 absorbs and attenuates the vibration transmitted by the suspension bracket 31, ensuring that the suspension bracket 31 does not directly transmit the vibration to the frame 1, reducing fatigue cracks caused by long-term high-load vibration at the connection points of the frame 1, reducing the risk of frame 1 breakage, thereby extending the service life of the motorcycle frame and reducing the use cost of the motorcycle frame. When the connection between the suspension bracket 31 and the engine 2 is damaged and needs to be replaced, the fixing bolt 33 is unscrewed to separate the suspension bracket 31 from the frame 1. Only the suspension bracket 31 and the engine 2 need to be replaced, without replacing the entire frame 1, reducing material consumption and further reducing the use cost of the motorcycle frame.

[0036] Reference Figure 1 The number of suspension brackets 31 can be one, two or more. In this embodiment, there are two suspension brackets 31. The two suspension brackets 31 are connected one-to-one to the inner walls of both ends of the frame 1 in the length direction, increasing the support points for the engine 2, thereby reducing the vibration generated during the operation of the engine 2 and further improving the connection stability between the engine 2 and the suspension brackets 31.

[0037] Reference Figure 2 and Figure 4The frame 1 is connected to a limiting component 4, which can limit the fixing bolt 33 within the threaded hole 11, thereby improving the connection stability between the suspension bracket 31 and the frame 1. The limiting component 4 includes multiple clamping rings 41, multiple sealing rings 42, multiple limiting plates 43, and multiple elastic elements 44. The clamping rings 41 can be made of rubber or silicone. In this embodiment, the clamping rings 41 are made of rubber, which has a certain deformation capability. The end faces of the multiple clamping rings 41 are connected to the inner walls on both sides of the frame 1 in the width direction at intervals. The clamping rings 41 correspond one-to-one with the threaded holes 11. The axis of the clamping rings 41 and the axis of the threaded holes 11 coincide. The inner ring wall of the clamping rings 41 can press against the outer circumference of the fixing bolt 33 to form a seal, so that the outside air is not easy to enter the threaded hole 11 from the clamping point between the clamping rings 41 and the fixing bolt 33 and corrode the fixing bolt 33, thereby achieving the limiting stability of the fixing bolt 33 within the threaded hole 11.

[0038] Reference Figure 2 and Figure 4 Multiple sealing rings 42 are connected at intervals to the inner walls of both sides of the frame 1 in the width direction. The sealing rings 42 correspond one-to-one with the clamping ring 41. The axis of the clamping ring 41 and the axis of the sealing ring 42 coincide. The inner ring wall of the sealing ring 42 and the outer peripheral surface of the fixing bolt 33 clamp the two sides of the clamping ring 41 to form a seal, making the outer ring wall of the clamping ring 41 less susceptible to pressure deformation, and further improving the sealing stability between the inner ring wall of the clamping ring 41 and the outer peripheral surface of the fixing bolt 33.

[0039] Reference Figure 2 and Figure 4The limiting plate 43 includes a sliding part 431, a limiting part 432, and a rod part 433. The sliding part 431 has a limiting cavity 434 for the sealing ring 42 to be embedded in on its surface. The limiting cavity 434 extends through both sides of the sliding part 431. The inner wall of the limiting cavity 434 has a sliding hole 435 for the rod part 433 to slide. The sliding hole 435 extends through the surface of the limiting plate 43 along its own axis. The limiting part 432 is integrally formed and fixed to the rod part 433 facing the limiting cavity 434. At the end of the rod, the sliding part 431 is slidably connected to the surface of the frame 1 away from the rod part 433. The sliding part 431 corresponds one-to-one with the threaded hole 11, and the sliding direction of the sliding part 431 is perpendicular to the axis of the threaded hole 11. The limiting part 432 is integrally formed and fixed to the surface of the sealing ring 42. The end face of the sealing ring 42 is provided with a limiting groove 421 for the limiting ring 5 to be inserted. When the sliding part 431 slides along the surface of the frame 1 towards the sealing ring 42, the limiting part 431 is slidably connected to the surface of the frame 1 away from the sealing ring 42. When the ring 42 slides in the direction of the sealing ring 42, the sealing ring 42 is embedded in the limiting cavity 434, and the limiting ring 5 faces the limiting groove 421, driving the rod part 433 to slide along the inner wall of the sliding hole 435 towards the sealing ring 42. The limiting ring 5 is embedded in the limiting groove 421, and the end face of the limiting part 432 abuts against the end face of the fixing bolt 33 to form a limit, so that the fixing bolt 33 is not easy to deviate in the inner wall of the threaded hole 11, thereby improving the connection stability between the suspension bracket 31 and the frame 1. At the same time, the surface of the limiting ring 5 abuts against the inner wall of the limiting groove 421 to form a seal, so that the outside air is not easy to enter the abutting ring 41 and the fixing bolt 33, further improving the sealing stability of the fixing bolt 33. In addition, the surface of the limiting ring 5 abuts against the inner wall of the limiting groove 421 and limits the sliding part 431 to the frame 1, so that the sliding part 431 is not easy to deviate in the frame 1, realizing the limiting stability of the sliding part 431 in the frame 1.

[0040] Reference Figure 2 and Figure 4 The elastic element 44 can be a compression spring or a tension spring. In this embodiment, the elastic element 44 is a compression spring with a certain deformation capability. One end of the elastic element 44 in the direction of elastic force is connected to the end face of the rod 433 protruding from the sliding part 431, and the other end of the elastic element 44 in the direction of elastic force is connected to the surface of the sliding part 431. The elastic element 44 has the elastic force to drive the rod 433 to slide towards the limiting cavity 434. The limiting ring 5 is embedded in the limiting groove 421, and the end face of the limiting part 432 abuts against the end face of the fixing bolt 33 to form a limiting tendency, so that the rod 433 is not easy to deviate in the inner wall of the sliding hole 435, thereby improving the abutting force between the end face of the limiting part 432 and the end face of the fixing bolt 33.

[0041] Reference Figure 4 and Figure 5The sliding part 431 has a slider 6 fixed on the surface of the frame 1. The surface of the frame 1 has a slide rail 12 for the slider 6 to slide. When the slider 6 slides on the inner wall of the slide rail 12, it drives the sliding part 431 to slide on the surface of the frame 1, ensuring that the sliding part 431 is not prone to deflection during the sliding process on the surface of the frame 1, thereby improving the stability of the sliding part 431 sliding on the surface of the frame 1.

[0042] Reference Figure 4 and Figure 5 An inflation assembly 7 is connected between the slider 6 and the frame 1. The inflation assembly 7 can inflate the inner cavity of the clamping ring 41, increasing the clamping force between the inner wall of the clamping ring 41 and the outer circumference of the fixing bolt 33. The inflation assembly 7 includes a magnetic block 1 71, a magnetic block 2 72, and an inflation piston 73. The inflation piston 73 can be made of rubber or silicone. In this embodiment, the inflation piston 73 is made of rubber and has a certain deformation capacity. An inflation channel 13 is provided in the frame 1 for the inflation piston 73 to slide. The sliding direction of the inflation piston 73 is parallel to the sliding direction of the slider 6. The magnetic block 1 71 is connected to the inflation piston 73. 3. On the surface of slider 6 facing magnetic block 71, magnetic block 72 is connected to the surface of slider 6 facing magnetic block 71. Magnetic block 71 and magnetic block 72 are attracted by opposite poles. When slider 6 slides along the inner wall of slide 12 toward the sealing ring 42, it drives the inflation piston 73 to slide along the inner wall of inflation channel 13 toward the sealing ring 42. The air pressure in inflation channel 13 increases, and the air in inflation channel 13 enters the inner cavity of the pressing ring bladder 41. The inner wall of the pressing ring bladder 41 is pressurized and expands, pressing against the outer circumference of the fixing bolt 33 to form a seal, further improving the sealing stability between the inner wall of the pressing ring bladder 41 and the outer circumference of the fixing bolt 33.

[0043] Reference Figure 4 and Figure 5 The frame 1 is connected to an indicator component 8, which can directly display the tightening status of the fixing bolt 33. The indicator component 8 includes an indicator piston 81, a power piston 82, and an elastic element 83. The materials of the indicator piston 81 and the power piston 82 can be rubber or silicone. In this embodiment, the materials of the indicator piston 81 and the power piston 82 are both rubber, which has a certain deformation capacity. The surface of the frame 1 facing the fixing bolt 33 is provided with a power flow channel 14 for the power piston 82 to slide. The sliding direction of the power piston 82 is parallel to the axis of the threaded hole 11. The elastic element 83 can be a compression spring or a tension spring. In this embodiment, the elastic element 83 is a compression spring, which has a certain deformation capacity. One end of the elastic element 83 in the elastic direction is connected to the surface of the power piston 82, and the other end of the elastic element 83 in the elastic direction is connected to the inner wall of the power flow channel 14. The elastic element 83 has the elastic force to drive the power piston 82 to slide away from the frame 1, and the end of the power piston 82 tends to protrude from the surface of the frame 1.

[0044] Reference Figure 4 and Figure 5 The frame 1 has an induction flow channel 15 on its surface for the sliding of the induction piston 81. The sliding direction of the induction piston 81 is parallel to the sliding direction of the power piston 82. The induction flow channel 15 is connected to the power flow channel 14. When the end of the fixing bolt 33 passes through the threaded hole and is screwed into the inner wall of the threaded hole 311, the end face of the fixing bolt 33 abuts against the end face of the power piston 82 and drives the power piston 82 to slide towards the frame 1. The end face of the power piston 82 is flush with the surface of the frame 1. At the same time, the power flow channel 14 is connected to the starting flow channel. The air in the power flow channel 14 enters the starting flow channel and drives the starting piston to slide away from the frame 1 along the inner wall of the starting flow channel. The surface of the starting piston is flush with the surface of the frame 1. The operator can directly judge the tightening of the fixing bolt 33 based on the depth of the induction piston 81 in the inner wall of the induction flow channel 15, thereby improving the installation efficiency of the motorcycle frame.

[0045] The implementation principle of a motorcycle frame according to an embodiment of this application is as follows: When the motorcycle is running, the vibration generated by the engine 2 is transmitted to the suspension bracket 31. An elastic sleeve 32 is clamped and fixed between the suspension and the frame 1. The elastic sleeve 32 has a certain deformation capacity and can absorb and attenuate the vibration transmitted by the suspension bracket 31, ensuring that the suspension bracket 31 does not easily transmit the vibration directly to the frame 1, reducing fatigue cracks caused by long-term high-load vibration at the connection point of the frame 1, reducing the risk of frame 1 breakage, thereby extending the service life of the motorcycle frame and reducing the use cost of the motorcycle frame. When the connection between the suspension bracket 31 and the engine 2 is damaged and needs to be replaced, the fixing bolt 33 is unscrewed to separate the suspension bracket 31 from the frame 1. Only the suspension bracket 31 and the engine 2 need to be replaced, without replacing the entire frame 1, reducing material consumption and further reducing the use cost of the motorcycle frame.

[0046] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
