Description

Technical Field

[0001] The present invention relates to the technical field of motorcycles, and in particular to a motorcycle with an integrated load-bearing body. Background Art

[0002] Off-road motorcycles are very popular among young people due to their powerful power and stylish appearance. They are a commonly used off-road tool with excellent off-road passing performance. At the same time, off-road motorcycles are very popular in off-road racing, adventure travel and leisure activities. They can provide exciting riding experiences on various terrains.

[0003] The body of an existing off-road motorcycle is mainly processed by combining a frame and sheet metal parts. The frame uses multiple welded tubular brackets to achieve the functions of connection, support and fixation. For example, Chinese Patent No. CN221418505U discloses a two-wheeled horizontal motorcycle frame and a two-wheeled motorcycle, which includes a vertical tube, a main beam tube is connected to the vertical tube, and the left and right sides of the main beam tube are respectively connected to a left beam tube and a right beam tube extending backward and downward; the left beam tube is provided with a left tube connected to the tail of the main beam tube, and the right beam tube is provided with a right tube connected to the tail of the main beam tube; the left beam tube, the main beam tube and the left tube and the right beam tube, the main beam tube and the right tube respectively form a triangular structure, and the motorcycle frame in this application is connected by multiple tubes. Chinese Patent No. CN221757660U discloses an off-road motorcycle, whose frame is composed of multiple tubes welded and sheet metal connections.

[0004] With respect to the existing technology, there are the following problems:

[0005] Most of the existing body structures adopt the above-mentioned multi-tube welding or a combination of multi-tube welding + sheet metal. This body structure has complex processes and is difficult to assemble during the production process of the motorcycle. At the same time, it is necessary to consider the installation layout of the motorcycle's power system, which will cause the motorcycle's structure to be not compact enough. At the same time, the frame made of multi-tube welding will increase the overall weight of the motorcycle, which cannot meet the growing demand for lightweight, high rigidity, and high impact toughness of off-road motorcycles. Summary of the invention

[0006] In view of the above-mentioned shortcomings of the prior art, an object of the present invention is to provide a motorcycle with an integrated load-bearing body, so as to solve the problem of bloated body structure in the prior art.

[0007] To achieve the above-mentioned and other related purposes, the present invention provides a motorcycle with an integrated load-bearing body, comprising:

[0016] Optionally, the front side of the controller is at least partially exposed from the vehicle body shell.

[0017] Optionally, the battery is a rectangular parallelepiped structure, and the length direction of the battery is arranged along the front-rear direction of the motorcycle.

[0018] Optionally, a support frame and a pressure plate for fixing a battery are provided on the inner wall of the vehicle body shell, the battery is supported on the support frame, and the pressure plate is located above the battery and presses the battery onto the support frame.

[0023] (2) In the present invention, since the entire body structure is directly stamped from a high-strength high-alloy plate, there is no need to use multi-tube welding to form the body, which optimizes the manufacturing process, improves the strength and rigidity of the body, reduces the manufacturing cost of the body, and has higher manufacturing efficiency and better product consistency. At the same time, the process of assembling the body onto the vehicle body is simplified, and the assembly efficiency is improved.

[0024] (3) In the present invention, the power system can be directly installed in the installation space formed inside the body shell by directly stamping the body shell from high-strength and high-alloy plates. The body shell can cover the power system. Compared with the prior art in which the power system is exposed to the body, the present invention can protect the power system, increase the service life of the power system, and at the same time ensure the normal operation of the power system.

[0025] (4) In the present invention, the power system is disposed as a whole inside the body shell by directly stamping the body shell from high-strength high-alloy sheet materials, which makes the appearance more beautiful.

[0044] The present invention provides a motorcycle with an integrated load-bearing body, such as Figure 1-Figure 14 shown.

[0045] Motorcycles with an integrated monocoque include:

[0046] The vehicle body includes a vehicle body shell 1 formed by plates, and an installation space 104 is formed in the vehicle body shell 1;

[0047] A power system, disposed in the installation space 104, for providing power to the motorcycle;

[0048] A front wheel 10 and a front frame 9, wherein the front wheel 10 is mounted on the front frame 9, and the front part of the vehicle body is connected to the front frame 9;

[0049] The rear wheel 11 is connected to the vehicle body through a flat fork assembly.

[0050] In this embodiment, the plate is directly used as the body shell 1 to connect the front frame 9 and the flat fork assembly. Compared with the prior art, the body in the present invention is directly formed by the plate, and the body does not need to be formed by multi-tube welding or a combination of multi-tubes and sheet metal. The structure is simpler, but since the body is integrally formed, the overall performance is better, the consistency and uniformity of the body are better, and the weight of the body is reduced, especially the lightweight performance of off-road vehicles and racing cars is improved.

[0051] In this embodiment, since the entire body structure is directly surrounded by plate materials, there is no need to use multi-tube welding to form the body, which achieves optimization in the manufacturing process, reduces the manufacturing cost of the body, and improves the manufacturing efficiency of the body. At the same time, the process of assembling the body to the vehicle body is simplified, thereby improving the assembly efficiency.

[0052] In this embodiment, the power system can be directly installed in the installation space 104 formed inside the body shell 1 through the body shell 1 which is only surrounded by plates. The body shell 1 can cover the power system. Compared with the exposed power system in the prior art, the present invention can protect the power system, increase the service life of the power system, and at the same time ensure the normal operation of the power system.

[0053] It is worth mentioning that in the present embodiment, the vehicle body is respectively connected to the front frame 9 and the fork assembly, so that the motorcycle can be assembled as a whole. Specifically, the front end of the vehicle body has a fixing portion 103, which is fixed by welding to the front frame 9 to achieve a stable connection between the front frame 9 and the vehicle body. The fork assembly and the vehicle body shell 1 are fixed by a detachable connection in the installation space 104. At the same time, since the overall vehicle body structure in the present embodiment is a plate-like structure, it is more convenient in the process of connecting with the fork assembly, thereby improving the assembly efficiency.

[0054] It should also be noted that in the present embodiment, the plate material is cold-formed using high-strength and high-alloy sheet metal. Specifically, the body shell 1 in the present embodiment is stamped using dual-phase steel. The stamping method ensures the smoothness and processing accuracy of the plate surface, and the overall appearance is better than hot forming, and the processing accuracy is also higher. By way of example, the material of the plate in the present embodiment can be specifically cold-formed using HC / DPD dual-phase steel, which has high strength and rigidity and light weight, which can not only meet the lightweight requirements of the motorcycle, but also ensure the strength and rigidity of the body.

[0055] It should also be noted that in this embodiment, in addition to the above-mentioned materials, other materials with the same or similar properties can also be used for processing to achieve the same structural strength.

[0056] In an exemplary embodiment, the plate includes a left molded plate 101 and a right molded plate 102 arranged on the left and right, and the left molded plate 101 and the right molded plate 102 are welded to form the vehicle body shell 1 .

[0057] In this embodiment, the vehicle body shell 1 is formed by connecting two forming plates, a left forming plate 101 and a right forming plate 102 . The two forming plates surround each other to form the vehicle body shell 1 and form an installation space 104 .

[0058] Exemplarily, the left forming plate 101 and the right forming plate 102 in this embodiment are formed by stamping two identical sheet metals, and can also be improved according to the needs of the motorcycle to achieve connection with various components.

[0059] Illustratively, in this embodiment, the front ends of the left forming plate 101 and the right forming plate 102 are interconnected to form a fixing portion 103, and the front end of the fixing portion 103 is arranged obliquely upward for connecting to the front frame 9. Specifically, the fixing portion 103 is a continuously arranged connecting edge, and the connecting edge includes a first edge and a second edge, the first edge is a straight edge, and the second edge is an arc edge, so as to adapt to the front frame 9.

[0060] Illustratively, in this embodiment, the left molding plate 101 and the right molding plate 102 are fixed by welding via a fixing portion 103, specifically by laser welding. During welding, the top and bottom of the left molding plate 101 and the right molding plate 102 are fixed, thereby fixing the first molding plate and the second molding plate. Therefore, the welding process takes less time and can achieve quick connection between the first molding plate and the second molding plate.

[0061] It is worth noting that, in this embodiment, in order to simplify the process flow, the left forming plate 101 and the right forming plate 102 are not connected at other positions except for the formed fixing portion 103, which is more convenient for the assembly of the vehicle body and also facilitates the installation of other components in the vehicle body shell 1, thereby improving the assembly efficiency.

[0062] In another embodiment, in addition to the above-mentioned body shell 1, the body is provided with a lower panel 105 on the left molding plate 101 and the right molding plate 102. The lower panel 105 is integrally arranged with the body panel, and the arrangement method is one-piece molding. A through hole 106 is formed between the lower panel 105 and the left molding plate 101 and the right molding plate 102. The through hole 106 is connected with the installation space 104. At the same time, a covering structure 2 is also provided on the body shell 1. The covering structure 2 includes a covering plate 203 and a connecting frame 201. The connecting frame 201 is fixed on the plate. The covering plate 203 is fixedly connected to the connecting frame 201. The covering plate 203 and the connecting frame 201 cover the through hole 106. A plurality of fixing strips 202 are provided on the connecting frame 201. The covering structure 2 provided in this embodiment can also improve the aesthetic performance of the entire body.

[0063] In this embodiment, since the connecting frame 201 is fixed on the lower enclosure 105, by providing a fixing strip 202 on the connecting frame 201 and welding the fixing strips 202 on the connecting frame 201 to each other, the connection strength between the left forming plate 101 and the right forming plate 102 can be further strengthened.

[0064] It should also be noted that in this embodiment, the plate can also be welded and fixed by a larger number of formed plates after stamping, and the number of plates can be adaptively increased or decreased according to the required conditions of the motorcycle body.

[0065] In an exemplary embodiment, the power system includes a battery 3, a motor 5 and a controller 4 mounted on a vehicle body shell 1. A heat dissipation channel is provided on the vehicle body shell 1 along the front-to-rear direction, and at least one of the battery 3, the motor 5 and the controller 4 is located on the heat dissipation channel.

[0066] In this embodiment, by providing a heat dissipation channel on the body shell 1, the power system can be cooled during the operation of the power system. Since in this embodiment, the body shell 1 is only connected at the fixing portion 103 and other parts are not connected, when the motorcycle moves forward, air will quickly pass through the installation space 104 from the front of the body shell 1 and be discharged from the rear of the body shell 1. Therefore, this path forms a heat dissipation channel, which is beneficial to the heat dissipation of the motorcycle's power system.

[0067] Exemplarily, in this embodiment, the motor 5 is located directly below the battery 3 and is arranged close to the battery 3, the controller 4 is located in front of the battery 3 and the motor 5, the controller 4 is located on the side of the vehicle body close to the front wheel 10, and is located at the inlet end of the heat dissipation channel, and the vehicle body shell 1 is formed with an exposed groove 108. When the controller 4 is installed, the heat dissipation side 401 (i.e., the front side) of the controller 4, which is mainly used for heat dissipation, passes through the exposed groove 108 so that it is exposed to the exposed groove 108. When the motorcycle moves forward, the cold air directly contacts the controller 4, and the controller 4 is directly cooled. An air inlet 107 is provided at the front of the vehicle body shell 1, which is located below the fixing portion 103. The air inlet 107 is arranged upward and is connected to the installation space 104. In this embodiment, the inlet end of the heat dissipation channel is the exposed groove 108 and the air inlet 107. Since the rear of the vehicle body shell 1 is in an open state and can be directly connected to the external environment, the outlet end is the rear of the vehicle body shell 1. Air can enter the installation space 104 through the air inlet 107 and finally be discharged from the rear of the body shell 1 to increase the air intake of the heat dissipation channel, so that the battery 3 and the motor 5 in the installation space 104 can be continuously cooled while the motorcycle is moving.

[0068] It is worth noting that, in the present embodiment, since the motor 5 is arranged directly below the battery 3 and close to the bottom of the battery 3, during installation, the gap between the battery 3 and the motor 5 should be as small as possible, and when the battery 3 is installed, its longest side is arranged toward the front and rear direction of the motorcycle. For example, the battery 3 is a rectangular parallelepiped structure as a whole, and its longest side is arranged toward the front and rear direction of the motorcycle. This layout setting can reduce the overall height of the motorcycle body, thereby reducing the overall center of gravity of the motorcycle, reducing the seat height, and reducing air resistance. At the same time, it can also increase the distance between the bottom of the motorcycle body and the ground, thereby improving the passing performance of the motorcycle, especially in racing.

[0069] A fender 204 is provided on the connecting frame 201, and the fender 204 seals the front and bottom of the body shell 1 to prevent excessive dust and dirt from entering the interior of the body shell 1. A heat dissipation cavity 206 is formed between the fender 204 and the connecting frame 201. The heat dissipation cavity 206 is "L"-shaped as a whole. The heat dissipation cavity 206 is connected to the exposed groove 108, and the exposed groove 108 is used to install the controller 4. Therefore, one end of the heat dissipation cavity 206 is in direct contact with the controller 4, and the other end of the heat dissipation cavity 206 leads to the rear of the body shell 1 and is connected to the external environment. Therefore, through the set heat dissipation cavity 206, direct heat dissipation of the radiator can also be achieved.

[0070] In this embodiment, connecting grooves 205 are provided between adjacent fixing bars 202 , and the connecting grooves 205 can connect the heat dissipation cavity 206 with the installation space 104 inside the body shell 1 , thereby dissipating heat for the battery 3 and the motor 5 inside the body shell 1 .

[0071] It should also be noted that in this embodiment, the exposed groove 108, the heat dissipation cavity 206 and the air inlet 107 are provided to improve the heat dissipation effect of the motorcycle. Compared with the three-electric system in the prior art that directly contacts the external environment for heat dissipation, the three in this embodiment cooperate in heat dissipation to achieve the same heat dissipation effect. At the same time, most of the power system is located inside the installation space 104, which can avoid direct contact between the power system and the external environment, thereby protecting the power system and improving the dirt resistance of the power system when the motorcycle is running.

[0072] It should also be noted that in this embodiment, due to the use of an integrated load-bearing body, an installation environment is provided for the controller 4. Compared with the prior art in which the controller 4 is installed on the battery 3 or on the frame, the radiator in this embodiment can utilize the airflow when the motorcycle is moving forward to dissipate heat, and its heat dissipation effect is better, thereby ensuring the normal operation of the controller 4 and improving the service life of the controller 4, the battery 3, and the motor 5.

[0073] It should also be noted that a first mounting frame and a second mounting frame are provided inside the vehicle body shell 1 , wherein the first mounting frame is used to connect the motor 5 and the controller 4 , and the second mounting frame is used to fix the motor 5 .

[0074] In an exemplary embodiment, a fixing assembly for fixing the battery 3 is provided on the inner wall of the vehicle body shell 1 , and the fixing assembly includes a support frame 301 and a pressure plate 307 . The battery 3 is supported on the support frame 301 , and the pressure plate 307 is located above the battery 3 and presses the battery 3 onto the support frame 301 .

[0075] In this embodiment, the battery 3 can be fixed in the installation space 104 of the vehicle body by setting the support frame 301 and the pressure plate 307. During installation, the support frame 301 is installed first, and then the battery 3 is installed on the support frame 301 for positioning, and then the pressure plate 307 is installed. After the pressure plate 307 is installed, the battery 3 can be fixed between the pressure plate 307 and the support frame 301.

[0076] Exemplarily, in this embodiment, the support frame 301 and the pressure plate 307 are respectively detachably connected to the vehicle body. Specifically, a plurality of first connecting members 303 are provided on the inner wall of the vehicle body shell 1, and a plurality of first connecting parts 302 corresponding to the first connecting members 303 are provided on the support frame 301, and the first connecting parts 302 are detachably connected to the first connecting members 303. A first positioning hole 304 is provided on the first connecting member 303, and a positioning part 305 corresponding to the first positioning hole 304 is provided at the bottom of the first connecting part 302, and the positioning part 305 can be used to cooperate with the first positioning hole 304 for positioning and fix the support frame 301 in the vehicle body shell 1. A plurality of second connecting members 309 are provided on the inner wall of the vehicle body shell 1, and a plurality of second connecting parts 308 corresponding to the second connecting members 309 are provided on the pressure plate 307, and the second connecting parts 308 are connected to the second connecting members 309 by fasteners 310. The second connecting member 309 is provided with a second positioning hole, and the fastener 310 includes a bolt and a nut. The bolt passes through the second connecting portion 308 and the second positioning hole and is connected to the nut. The nut fixes the pressing plate 307 on the second connecting member 309 and presses the battery 3 onto the support frame 301.

[0077] For example, since the battery 3 is a horizontally placed rectangular structure, the support frame 301 in this embodiment is overall in an "X" shape, so that the bottom of the battery 3 can be stably supported, and the pressure plate 307 is similar to a "big" shape to achieve the function of fixing the battery 3.

[0078] Exemplarily, a limiting seat 306 is provided on the support frame 301 in this embodiment, and the limiting seat 306 can be used to position the outer edge of the battery 3 .

[0079] It is worth noting that a limiting assembly is further provided between the battery 3 and the pressing plate 307, and the battery 3 and the pressing plate 307 can be further fixed by the provided limiting assembly to avoid misalignment between the top of the battery 3 and the pressing plate 307. Specifically, the limiting assembly includes a first limiting plate 311 and a second limiting plate 313, the first limiting plate 311 is provided on the pressing plate 307, the second limiting plate 313 is provided on the battery 3, and a fixing plate 316 is provided between the first limiting plate 311 and the second limiting plate 313, and the fixing plate 316 can be used to fix the first limiting plate 311 and the second limiting plate 313. A fixing seat 315 is provided on the battery 3, and the fixing plate 316 is connected with the fixing seat 315 through an insertion, and the fixing plate 316 passes through both ends of the fixing seat 315, the first limiting plate 311 has a first convex portion protruding upward, and a first limiting groove 312 is formed between the first convex portion and the pressure plate 307, the second limiting plate 313 has a second convex portion protruding upward, and a second limiting groove 314 is formed between the second convex portion and the battery 3, one end of the fixing plate 316 is located in the first limiting groove 312, and the other end of the fixing plate 316 is located in the second limiting groove 314, and the first limiting groove 312 and the second limiting groove 314 can be used to limit the middle plate in the width direction. In this embodiment, the first limiting plate 311 is installed on the pressure plate 307 by screws, and the second limiting plate 313 is installed on the battery 3 by screws, and the width of the first limiting groove 312 and the second limiting groove 314 is adapted to the width of the fixing plate 316. When the first limiting plate 311 and the second limiting plate 313 are respectively fixed on the pressure plate 307 and the battery 3, the fixing plate 316 will be slightly bent downward to fix the fixing plate 316 between the first limiting plate 311 and the second limiting plate 313, and at the same time, the fixing plate 316 is pressed tightly in the fixing seat 315. Therefore, the connection between the pressure plate 307 and the battery 3 can be achieved through the limiting assembly, thereby improving the fixing effect of the battery 3.

[0080] It should also be noted that in this embodiment, other fixing structures may be used to enhance the fixing effect on the battery 3 .

[0081] In an exemplary embodiment, the fork assembly includes a fork shaft 7 and a fork body 6, wherein a pressing sleeve 603 is provided on the fork body 6, the fork shaft 7 is fixedly connected to the vehicle body, combined bearings are provided at both ends of the fork shaft 7, and the fork body 6 is rotatably connected to the fork shaft 7 through the combined bearings.

[0082] In this embodiment, the fork assembly is an important component of the motorcycle and is a suspension part, which enables the fork to rotate and fit on the motorcycle's central axis through the fork shaft 7. The axle tube of the steel welded fork in the prior art is rotated and fit with the central axis through a bearing, such as a needle bearing, which has the advantages of small rotational resistance and controllable radial clearance, but the axial clearance is difficult to control, and the axle tube cannot be axially positioned by a single bearing such as a needle bearing. In order to avoid structural interference with the frame during design, an axial gap is left between the fork shaft 7 and the body of the vehicle. Therefore, when the fork body 6 is subjected to axial and radial forces at the same time (such as turning), the existing bearings cannot support the radial load of the motorcycle. After the fork system is subjected to the radial load, the fork body 6 may produce axial movement, causing wear on the body and a decrease in the synchronization of the front and rear wheels 11.

[0083] In this embodiment, the rear wheel 11 can be supported and fixed by the provided flat fork assembly, and the provided combined bearing can act on the axial and radial directions of the flat fork shaft 7.

[0084] Exemplarily, a sleeve 701 is provided on the flat fork shaft 7, and a first positioning seat 802 and a second positioning seat 803 for positioning the bearing assembly 8 are provided on the sleeve 701. The first positioning seat 802 is arranged against the end surface of the first bearing 801. The bearing assembly 8 includes a first bearing 801, a second bearing 804 and a third bearing 805. The first bearing 801 is sleeved on the sleeve 701 and is located between the first positioning seat 802 and the second positioning seat 803. The pressing sleeve 603 presses the first bearing 801 on the sleeve 701. The first bearing 801 is pressed on the first positioning seat 802 through the pressing sleeve 603, and the second bearing 804 is pressed on the second positioning seat 803 through the pressing sleeve 603. The first sleeve 701 has a first acting portion 8011 and a second acting portion 8012. The first acting portion 8011 is sleeved on the sleeve 701 and acts on the axial direction of the flat fork shaft 7, and the second acting portion 8012 acts on the radial direction of the flat fork shaft 7. The second bearing 804 has a third acting portion 8041, and the third bearing 805 has a fourth acting portion 8051. The third acting portion 8041 and the fourth acting portion 8051 both act on the radial direction of the fork shaft 7, and the third acting portion 8041 and the fourth acting portion 8051 are arranged back to back. At the same time, in this embodiment, the second bearing 804 and the third bearing 805 are also arranged to act on the radial direction of the fork shaft 7, so that the support for the radial load can be further improved. Specifically, when the fork shaft 7 is subjected to a radial load, the radial load is synchronously transmitted to the sleeve 701 and borne by the second bearing 804 and the third bearing 805, respectively. The second bearing 804 and the third bearing 805 are arranged on both sides of the first bearing 801, and the third acting portion 8041 and the fourth acting portion 8051 are arranged back to back. Therefore, when the motorcycle turns left or right, the radial load can be supported.

[0085] Exemplarily, in this embodiment, the pressing sleeve 603 has a first pressing portion 6031 and a second pressing portion 6032. The first pressing portion 6031 presses the first bearing 801 onto the shaft sleeve 701, the second pressing portion 6032 presses the second bearing 804 onto the first positioning seat 802, and the second pressing portion 6032 presses the third bearing 805 onto the second positioning seat 803. The cross section of the pressing sleeve 603 is an overall "T" shape, wherein the downward middle portion is the first pressing portion 6031, which is inserted into the first bearing 801 to press the first bearing 801 onto the shaft sleeve 701, and the horizontal portion at the top is the second pressing portion 6032, which simultaneously presses the second bearing 804 and the third bearing 805. Therefore, the pressing sleeve 603 on the flat fork body 6 can press the three bearings at the same time, and the fixing effect is better.

[0086] Exemplarily, the left and right ends of the flat fork shaft 7 are rotatably connected to the vehicle body, and a fixing sleeve 702 is provided between the sleeves 701 installed at both ends of the flat fork shaft 7, and an installation gap is provided between the sleeves 701 and the fixing sleeve 702. The sleeves 701 and the fixing sleeve 702 can both protect the flat fork shaft 7, and to a certain extent, can prevent the flat fork shaft 7 from being damaged, and can also be used to position the second positioning seat 803. Specifically: the second positioning seat 803 is "T" shaped. During installation, the second positioning seat 803 is first installed on the flat fork shaft 7, so that the end face of the second positioning seat 803 abuts against the fixing sleeve 702, and then the sleeve 701 and the third bearing 805 and the sleeve 701 are installed, and then the first bearing 801 is sleeved on the sleeve 701, and then the first positioning seat 802 and the second bearing 804 are installed, and finally the pressing sleeve 603 is inserted into the first bearing 801 to achieve the installation of the bearing assembly 8.

[0087] For example, in this embodiment, a stopper 806 is provided on the fork shaft 7, and the stopper 806 is connected to the vehicle body. Due to the stopper 806, even if the bearing fails, the fork shaft 7 will rub against the stopper 806 when it moves axially, but will not rub against the vehicle body, and the stopper 806 can be replaced.

[0088] Exemplarily, the fork body 6 includes a left fork 601 bracket and a right fork 602 bracket, both of which are provided with a pressing sleeve 603, and a connecting block for mutual connection is provided between the left fork 601 bracket and the right fork 602 bracket.

[0089] In this embodiment, the fork body 6 is a left fork 601 and a right fork 602, and both are provided with a pressing sleeve 603, so there are two bearing assemblies 8, which are respectively arranged on the pressing sleeves 603 of the left fork 601 and the right fork 602. The bearing assembly 8 on the left fork 601 is symmetrically arranged with the bearing assembly 8 on the right fork 602, so the fork shaft 7 can be supported in axial and radial directions when the motorcycle turns left or right, so as to avoid circumferential movement of the fork shaft 7.

[0090] Exemplarily, the left flat fork 601 bracket and the right flat fork 602 bracket are both provided with a plurality of reinforcing ribs 604. The provided reinforcing ribs 604 can improve the structural strength of the left flat fork 601 and the right flat fork 602.

[0091] It is worth mentioning that the combined bearing in this embodiment adopts the above-mentioned structure, and three bearings are used in combination to act on the axial and radial directions of the fork shaft 7. When the fork body 6 is subjected to axial and radial forces, the fork shaft 7 is supported and limited in the axial direction and in the radial direction, thereby avoiding axial movement of the fork shaft 7 and improving the consistent performance of the front and rear wheels 11.

[0092] It should also be noted that other structural forms of combined bearings can also be used in this embodiment, and the specific structure of the combined bearing is not limited. For example, it must satisfy the requirement of being able to limit the axial direction of the flat fork shaft 7 and the radial direction of the flat fork shaft 7. For example, an additional fixed structure is provided on the flat fork body 6 to fix the combined bearing on the flat fork body 6 to support and limit the flat fork body 6.

[0093] In an exemplary embodiment, the motorcycle is further provided with a shock absorber 13 , and is further provided with a tail rack 12 , on which a seat cushion is provided, and the tail rack 12 is installed on the top of the vehicle body shell 1 .

[0094] In summary, the present invention adopts an integrated load-bearing body structure, and the body shell 1 is directly formed by sheet metal, so the lightweight performance of the motorcycle is improved, the manufacturing process is optimized, the manufacturing cost of the body is reduced, the manufacturing efficiency is increased, the assembly process is simplified, and at the same time, the overall body appearance is more beautiful. Therefore, the integrated load-bearing body adopted improves the comprehensive performance of the motorcycle.
