Description

Technical Field

[0001] This utility model belongs to the field of motorcycle frame technology and relates to a high-performance three-wheeled motorcycle frame structure. Background Technology

[0002] Three-wheeled motorcycles, as a common mode of transportation, have advantages such as strong load-bearing capacity and good stability, and are widely used in passenger and freight transport. However, with the increasing demands for motorcycle performance, high-performance three-wheeled motorcycles face greater challenges in terms of power, handling, and comfort.

[0003] Currently, the frame structure of most three-wheeled motorcycles on the market adopts a traditional unibody frame design. This structure has some obvious shortcomings when facing complex road conditions. On the one hand, the unibody frame has high rigidity, and when the vehicle is traveling on bumpy roads, the impact force of the road surface is directly transmitted to the rear frame. This not only affects the passenger's riding comfort but may also damage items carried in the tail box. On the other hand, the maintenance and repair of unibody frames are also more inconvenient. When a part of the frame is damaged, it is often necessary to disassemble and repair the entire frame, increasing maintenance costs and time. Utility Model Content

[0004] The purpose of this invention is to address the above-mentioned problems by providing a high-performance three-wheeled motorcycle frame structure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0010] In the above-mentioned high-performance three-wheeled motorcycle frame structure, the main frame and the rear frame are movably connected, and a connecting shaft is provided between the two front longitudinal beams and the two rear longitudinal beams. The two ends of the connecting shaft are movably connected to the front longitudinal beams and the rear longitudinal beams, respectively.

[0011] In the above-mentioned high-performance three-wheeled motorcycle frame structure, the buffer component is a helical spring, the top of the helical spring is fixedly connected to the vertical connecting frame, and the bottom of the helical spring is fixedly connected to the horizontal connecting frame.

[0012] In the above-mentioned high-performance three-wheeled motorcycle frame structure, two rear wheel mounting brackets are installed on the rear side of the horizontal connecting frame, and the rear wheel mounting brackets are movably hinged to the horizontal connecting frame.

[0013] In the above-mentioned high-performance three-wheeled motorcycle frame structure, a reinforcing bracket is fixedly installed on one side of the main frame. The reinforcing bracket includes a connecting plate and two sets of reinforcing rods. The bottom of the reinforcing rods is fixedly connected to the front longitudinal beam, and the connecting plate is fixedly installed on the front end of the reinforcing rods.

[0014] In the above-mentioned high-performance three-wheeled motorcycle frame structure, a support assembly is installed on one side of the main frame.

[0025] The present invention will be further described below with reference to the accompanying drawings.

[0026] like Figure 1-4As shown, a high-performance three-wheeled motorcycle frame structure includes a frame body 1, which includes a main frame 2, a rear frame 3, and a connecting mechanism 4. The main frame 2 and the rear frame 3 are detachably connected by the connecting mechanism 4. The main frame 2 includes a front crossbeam 5, a rear crossbeam 6, two front longitudinal beams 7, and a front mounting seat 8. The two front longitudinal beams 7 are arranged in parallel. The front crossbeam 5 and the rear crossbeam 6 are respectively connected to the front and rear ends of the two front longitudinal beams 7 to form a rectangular frame structure. The front crossbeam 5 has a front mounting seat 8 for mounting the front assembly in the middle. The rear frame 3 includes two rear longitudinal beams 9, which are trapezoidal in shape. The connecting mechanism 4 includes a horizontal connecting frame 10 and a vertical connecting frame 11. The horizontal connecting frame 10 is mounted on the main frame 2, and the vertical connecting frame 11 is mounted on the rear frame 3. A buffer assembly 12 is provided between the horizontal connecting frame 10 and the vertical connecting frame 11.

[0027] Furthermore, a column rod 13 is provided between the front mounting seat 8 and the front crossbeam 5. The bottom of the column rod 13 is fixedly connected to the front crossbeam 5, and the upper end of the column rod 13 is fixedly welded to the front mounting seat 8. A reinforcing plate 14 is welded between the column rod 13 and the front mounting seat 8.

[0028] In this embodiment, the front mounting base 8 is securely connected to the front crossbeam 5 via the column rod 13, enhancing the stability and load-bearing capacity of the front section. The reinforcing plate 14 further improves the strength and rigidity of the connection, ensuring the stable installation of the front components and driving safety under complex road conditions.

[0029] Furthermore, a connecting rod 15 is fixedly connected to one side of each of the two front longitudinal beams 7. The connecting rod 15 and the front longitudinal beam 7 are integrally formed. One end of the connecting rod 15 is provided with a fixing part 16. The fixing part 16 is a semi-circular arc structure, and the two fixing parts 16 are fixedly installed on the outside of the column rod 13.

[0030] In this embodiment, the connecting rod 15 not only enhances the connection strength between the front longitudinal beams 7, but also improves the overall stability and torsional resistance of the frame through the tight fit between the fixing part 16 and the upright rod 13. This one-piece connection method reduces welding points, thereby reducing stress concentration problems caused by welding and improving the durability and safety of the frame. The semi-circular arc structure of the fixing part 16 can better fit the outer surface of the upright rod 13, achieving stable support and ensuring that the frame can remain stable when subjected to various complex loads.

[0031] Furthermore, an engine mounting bracket 17 is provided on the inner side of the middle part of the two front longitudinal beams 7, and the outer side of the engine mounting bracket 17 is fixedly connected to the inner side of the front crossbeam 5, the rear crossbeam 6 and the two front longitudinal beams 7 respectively.

[0032] In this embodiment, the engine mounting bracket 17 securely fixes the engine to the core position of the frame, ensuring the normal operation of the engine and improving the overall load-bearing capacity and impact resistance of the frame through multi-point fixing connection.

[0033] Furthermore, the main frame 2 and the rear frame 3 are movably connected, and a connecting shaft 18 is provided between the two front longitudinal beams 7 and the two rear longitudinal beams 9. The two ends of the connecting shaft 18 are movably connected to the front longitudinal beams 7 and the rear longitudinal beams 9, respectively.

[0034] In this embodiment, the connecting shaft 18 enables flexible relative movement between the front longitudinal beam 7 and the rear longitudinal beam 9, which not only enhances the flexibility and adaptability of the frame, but also helps to improve the vehicle's driving stability and handling under different road conditions.

[0035] Furthermore, the buffer assembly 12 is a helical spring 19, the top of the helical spring 19 is fixedly connected to the vertical connecting frame 11, and the bottom of the helical spring 19 is fixedly connected to the horizontal connecting frame 10.

[0036] In this embodiment, the coil spring 19 serves as a buffer component 12, effectively absorbing and dispersing the impacts and vibrations experienced by the frame during driving, protecting the frame and its components from damage. It also provides users with a more comfortable and safer driving experience.

[0037] Furthermore, two rear wheel mounting brackets 20 are installed on the rear side of the horizontal connecting frame 10, and the rear wheel mounting brackets 20 are movably hinged to the horizontal connecting frame 10.

[0038] Furthermore, a reinforcing bracket 21 is fixedly installed on one side of the main frame 2. The reinforcing bracket 21 includes a connecting plate 22 and two sets of reinforcing rods 23. The bottom of the reinforcing rods 23 is fixedly connected to the front longitudinal beam 7, and the connecting plate 22 is fixedly installed on the front end of the reinforcing rods 23.

[0039] In this embodiment, the reinforcing bracket 21 enhances the structural strength and stability of the main frame 2. The two sets of reinforcing rods 23, fixedly connected to the front longitudinal beam 7 at their bottom, tightly link the main frame 2 with the key structural components of the frame, forming a more robust overall structure. This not only improves the load-bearing capacity of the frame but also effectively resists external impacts and vibrations, ensuring the stability and safety of the vehicle during operation.

[0040] Furthermore, a support assembly 24 is installed on one side of the main frame 2. The support assembly 24 includes a mounting base 25 and a movable support rod 26. The mounting base 25 is fixedly installed on the front crossbeam 5 by bolts, and one end of the movable support rod 26 is movably hinged to the mounting base 25.

[0041] In this embodiment, the support rod 26 can conveniently support the tricycle when it is parked, preventing the motorcycle from tipping over.

[0042] Furthermore, a shock absorber bracket 28 is provided at the bottom of the rear frame 3, and a tail box bracket 27 is provided at the top of the rear frame 3.

[0043] In this embodiment, the shock absorber bracket 28 provides a stable support point for the rear frame 3, and is used to install the shock absorber, effectively absorbing and dispersing vibrations generated during driving, improving ride comfort and vehicle stability. The tailgate bracket 27 is used to install the tailgate, increasing storage space and facilitating the carrying of items.

[0044] The working principle of this utility model is as follows:

[0045] When the three-wheeled motorcycle travels on different road conditions, the main frame 2 and rear frame 3 of the chassis body 1 achieve flexible relative movement through the connecting mechanism 4. Especially on rough and uneven roads, the connecting shaft 18 allows relative rotation between the front longitudinal beam 7 and the rear longitudinal beam 9, thereby enhancing the flexibility and adaptability of the chassis. This design enables the vehicle to better adapt to complex and changing road conditions, improving driving stability and handling. At the same time, the coil spring 19 in the buffer assembly 12 effectively absorbs and disperses the impact and vibration experienced by the chassis during driving, protecting the chassis and its components, and providing the driver with a more comfortable and safer driving experience. In addition, the setting of the reinforcing bracket 21 and the support assembly 24 further enhances the structural strength and stability of the chassis, ensuring the safety and reliability of the vehicle during driving. The shock absorber bracket 28 and the tail box bracket 27 provide stable support points and storage space, respectively, improving the practicality and convenience of the vehicle.
