Description

Technical Field

[0001] This application relates to the field of vehicle technology, and in particular to a motorcycle. Background Technology

[0002] Motorcycles are vehicles that are steered by using handlebars to turn the front wheel. They are lightweight, agile, and fast, and are widely used in patrol, passenger and freight transportation, and other fields.

[0003] Motorcycles typically consist of a frame, body panels, running gear, suspension system, powertrain, and braking system. The running gear includes the wheels. The braking system includes the wheel braking mechanisms that brake the wheels, such as brake discs and calipers. To improve the protection of wheel components, existing motorcycles often have protective covers or similar structures installed at the wheels. However, these covers can reduce airflow at the wheels, preventing the braking mechanism from dissipating heat and causing it to overheat, thus reducing braking performance. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, the purpose of this application is to provide a motorcycle with better braking performance.

[0005] To achieve the above objectives, this application adopts the following technical solution:

[0006] A motorcycle includes a frame, a body panel, wheels, a powertrain, a suspension system, and a braking system. The body panel is at least partially located on and connected to the frame. The wheels are connected to the frame and include hubs. The powertrain is drive-connected to the wheels. The suspension system connects the wheels to the frame. The braking system includes a wheel brake mechanism mounted on one side of the wheel. The motorcycle also includes a guard located on the side of the wheel where the wheel brake mechanism is mounted and has airflow channels. The airflow channels are formed along the width of the frame and extend through the guard. At least a portion of the guard is recessed towards the wheel brake mechanism to form a flow-guiding structure communicating with the airflow channels, allowing air to enter the airflow channels from the flow-guiding structure.

[0007] Furthermore, the guide hole includes a first vent and a second vent that are interconnected. The first vent is located on the side of the cover away from the wheel braking mechanism, and the second vent is located on the side of the cover close to the wheel braking mechanism. The second vent faces the wheel braking mechanism, and the first vent is opened in the guide structure.

[0008] Furthermore, the airflow guiding structure includes an airflow guiding ramp for guiding air to the first vent, the airflow guiding ramp being connected to the first vent; and a longitudinal plane perpendicular to the width direction of the frame is defined, the angle between the airflow guiding ramp and the longitudinal plane being in the range of 10° to 20°.

[0009] Furthermore, the angle between the guide slope and the longitudinal plane ranges from 13° to 18°.

[0010] Furthermore, the flow guiding structure also includes a windproof surface for blocking airflow, which is connected to the first vent. The first vent includes a first connection position and a second connection position, which are located at different positions on the first vent. The flow guiding slope is connected to the first connection position, and the windproof surface is connected to the second connection position.

[0011] Furthermore, the windbreak surface is basically a "U" shaped curved surface, and the windbreak surface and the guide slope are connected. The windbreak surface and the guide slope are arranged around the first vent.

[0012] Furthermore, the protective cover includes a base, a cover, and a connecting structure. The base is connected to the wheel hub, and the cover is connected to the base. Along the width direction of the frame, the base is located between the wheel braking mechanism and the cover. The first vent and the air guide structure are both located on the cover, and the second vent is located on the base. The connecting structure is a hollow structure. When the base is connected to the cover, the first vent and the second vent are connected through the connecting structure.

[0013] Furthermore, a limiting step is formed on the side of the cover away from the airflow structure, and the limiting step is connected to the first vent; a connecting protrusion is formed on the side of the base facing the cover, and the connecting protrusion is connected to the second vent; when the base is connected to the cover, the connecting protrusion abuts against the limiting step to form a connecting structure.

[0014] Furthermore, multiple covers are provided, and the multiple covers are evenly distributed on the base along the circumference of the wheel. Each cover is provided with a first vent. The base is provided with multiple second vents, and each second vent is connected to a first vent.

[0015] Furthermore, the wheel braking mechanism includes a brake disc and a brake caliper. The brake disc is connected to the wheel hub, and the brake caliper is connected to the suspension system. The brake caliper is capable of braking the brake disc. The airflow holes face the brake disc and the brake caliper.

[0016] In the aforementioned motorcycle, the protective cover can protect the components at the wheel, and by opening air guide holes on the cover to guide airflow, the air circulation rate at the wheel can be improved. The airflow is also guided by the air guide structure, which is conducive to the heat dissipation of the wheel braking mechanism, can prevent the wheel braking mechanism from overheating, and thus improve the braking performance of the wheel braking mechanism.

[0024] To enable those skilled in the art to better understand the present application, the technical solutions in specific embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.

[0025] To enable those skilled in the art to better understand the present application, the technical solutions in specific embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.

[0026] like Figure 1 As shown, this application provides a motorcycle 100, which includes a frame 11, a body panel 12, a running system 13, a suspension system 14, a powertrain 16, and a braking system 17.

[0027] The frame 11 serves as the basic framework of the motorcycle 100, supporting the body panel 12, the running system 13, the suspension system 14, and the powertrain 16. The body panel 12 is at least partially located on and connected to the frame 11, protecting the internal components of the motorcycle 100. The running system 13 includes wheels 131 located at least partially beneath the frame 11. Specifically, the wheels 131 are connected to the frame 11 and include hubs 1311, with the suspension system 14 connecting the hubs 1311 to the frame 11. The powertrain 16 is drive-driven to the wheels 131, rotating them. The braking system 17 includes a wheel brake mechanism 171 mounted on one side of the wheels 131, enabling the motorcycle 100 to decelerate and brake.

[0028] For ease of description, this application defines the directions of front, back, left, right, up, and down. The front-back direction refers to the length direction of the motorcycle frame 11, the left-right direction refers to the width direction of the motorcycle frame 11, and the up-down direction refers to the height direction of the motorcycle frame 11. In this embodiment, the directions of front, back, left, right, up, and down are based on the motorcycle 100 traveling on a level road surface, not on a sloping road surface.

[0029] like Figure 2 and Figure 3 As shown, in one embodiment, the motorcycle 100 also includes a guard 18, which is located on the side of the wheel 131 where the wheel brake mechanism 171 is mounted. This arrangement allows the guard 18 to block splashed dirt, sand, and other impurities, preventing them from corroding the wheel brake mechanism 171 and the wheel 131, thus improving their service life. In some embodiments, the guard 18 is located on the right side of the wheel brake mechanism 171, so that it can block dirt, sand, and other impurities splashing from the right side. Furthermore, this application will describe an example where the guard 18 is located on the right side of the wheel brake mechanism 171.

[0030] Specifically, the guard 18 has air guide holes 181, which are formed along the width of the frame 11 and extend through the guard 18. This arrangement allows air to flow through the air guide holes 181 on both sides of the guard 18 along the width of the frame 11, improving airflow on both sides of the guard 18. This, in turn, helps dissipate heat from the wheel brake mechanism 171 located on the right side of the guard 18. Furthermore, the installation of the guard 18 prevents brake fade due to overheating of the wheel brake mechanism 171, thus improving its braking performance. Secondly, the air guide holes 181 also facilitate heat dissipation from the guard 18. When heat generated during braking of the wheel 131 is transferred to the guard 18, it can be dissipated through the air guide holes 181, preventing deformation of the guard 18 due to excessive temperature and extending its service life.

[0031] More specifically, the shield 18 is at least partially recessed towards the wheel braking mechanism 171 to form a flow guiding structure 182. The flow guiding structure 182 is used to guide airflow and is located on the side of the shield 18 away from the wheel braking mechanism 171. Furthermore, the flow guiding structure 182 communicates with the flow guiding hole 181 so that air can enter the flow guiding hole 181 from the flow guiding structure 182. With this configuration, the air on the right side of the shield 18 can be guided through the flow guiding structure 182 to the wheel braking mechanism 171 located on the left side via the flow guiding hole 181, thereby further improving the heat dissipation effect of the wheel braking mechanism 171 and improving the braking performance of the wheel braking mechanism 171.

[0032] In one implementation, the air guide hole 181 includes a first vent 1811 and a second vent 1812 that are interconnected. Specifically, the first vent 1811 is located on the side of the cover 18 away from the wheel brake mechanism 171, and the second vent 1812 is located on the side of the cover 18 facing the wheel brake mechanism 171. In this embodiment, the first vent 1811 is located on the right side of the cover 18, and the second vent 1812 is located on the left side of the cover 18. The first vent 1811 is formed in the air guide structure 182. This arrangement allows air to circulate between the left and right sides of the cover 18 through the first vent 1811 and the second vent 1812, and the air can be guided by the air guide structure 182 to facilitate heat dissipation from the wheel brake mechanism 171. More specifically, the second vent 1812 faces the wheel brake mechanism 171. This configuration allows air flowing through the second vent 1812 to flow toward the wheel brake mechanism 171 when air flows through the guide hole 181, thereby further improving the heat dissipation effect of the wheel brake mechanism 171.

[0033] In another embodiment, the airflow guiding structure 182 is located on the left side of the protective cover 18 and recessed towards the right side of the protective cover 18, and the second vent 1812 is formed in the airflow guiding structure 182. With this configuration, the airflow guiding structure 182 can guide the air on the left side of the protective cover 18 to the second vent 1812, and then discharge it from the first vent 1811 through the second vent 1812. Through this configuration, the heat generated by the wheel braking mechanism 171 located on the left side of the protective cover 18 can be discharged sequentially through the airflow guiding structure 182, the second vent 1812, and the first vent 1811, thereby preventing the wheel braking mechanism 171 from overheating due to insufficient heat dissipation, and thus improving the braking stability of the wheel braking mechanism 171.

[0034] In another embodiment, airflow guiding structures 182 are provided on both the left and right sides of the protective cover 18. These structures simultaneously guide airflow on both sides of the protective cover 18, improving air circulation and thus enhancing heat dissipation for the wheel braking mechanism 171. Therefore, this application does not limit the location of the airflow guiding structures 182, as long as airflow on both sides of the protective cover 18 is achieved through the airflow guiding structures 182. Furthermore, this application will describe an example where the airflow guiding structure 182 is located on the side of the protective cover 18 away from the wheel braking mechanism 171.

[0035] In one implementation, the airflow guiding structure 182 includes a guide slope 1821 for guiding air to the first vent 1811, and the guide slope 1821 is connected to the first vent 1811. With this configuration, as the wheel hub 1311 drives the guard 18 to rotate, the guide slope 1821 can guide the air on the left side of the guard 18, allowing the air to flow through the guide slope 1821 to the first vent 1811, and then through the first vent 1811 to the second vent 1812, thus enabling air circulation on both sides of the guard 18 and dissipating heat from the wheel braking mechanism 171.

[0036] A longitudinal plane 101 perpendicular to the width direction of the frame 11 is defined, and the angle α between the guide slope 1821 and the longitudinal plane 101 ranges from 10° to 20°. Specifically, the angle α between the guide slope 1821 and the longitudinal plane 101 ranges from 13° to 18°. More specifically, the angle α between the guide slope 1821 and the longitudinal plane 101 is 15°. This setting avoids the guide slope 1821 being too steep, which could cause the airflow to form vortices in the guide structure 182, thus avoiding affecting the airflow into the first vent 1811 for air circulation, thereby improving the heat dissipation effect on the wheel braking mechanism 171. Secondly, it also avoids the aforementioned angle α being too small, which could result in the guide slope 1821 being too steep, thus avoiding the airflow velocity in the guide structure 182 being too low, resulting in low airflow rate in the guide hole 181, which is beneficial to further improving the heat dissipation effect on the wheel braking mechanism 171.

[0037] like Figure 4 As shown, in one embodiment, the flow guiding structure 182 further includes a windbreak surface 1822 for blocking airflow, and the windbreak surface 1822 is connected to the first vent 1811. With this configuration, when the flow guiding slope 1821 guides the airflow, the windbreak surface 1822 can block the airflow guided by the flow guiding slope 1821, preventing the airflow from passing over the flow guiding structure 182 and thus preventing the airflow from entering the first vent 1811, thereby improving the airflow rate of the flow guiding hole 181.

[0038] Specifically, the first vent 1811 includes a first connecting position 1811a and a second connecting position 1811b. A guide slope 1821 is connected to the first connecting position 1811a, and a windproof surface 1822 is connected to the second connecting position 1811b. The different positions of the first connecting position 1811a and the second connecting position 1811b on the first vent 1811 allow the connection position of the guide slope 1821 to the first vent 1811 to differ from the connection position of the windproof surface 1822 and the second vent 1812. This avoids the windproof surface 1822 directly blocking the airflow guided by the guide slope 1821, preventing the airflow guided by the guide slope 1821 from failing to flow into the first vent 1811 and thus reducing the airflow rate of the guide hole 181. This, in turn, improves the heat dissipation effect on the wheel braking mechanism 171.

[0039] More specifically, the windbreak surface 1822 is basically a U-shaped curved surface, and the windbreak surface 1822 and the guide slope 1821 are connected, with the windbreak surface 1822 and the guide slope 1821 arranged around the first vent 1811. This arrangement can improve the blocking effect of the windbreak surface 1822 on the airflow guided by the guide slope 1821, thereby increasing the amount of air entering the first vent 1811, and thus improving the gas flow rate on the left and right sides of the protective cover 18.

[0040] It should be noted that this application does not limit the shape of the windbreak surface 1822, as long as it can block the airflow.

[0041] like Figures 4 to 7 As shown, in one embodiment, the protective cover 18 includes a base 183, a cover 184, and a connecting structure 185. The base 183 is connected to the wheel hub 1311, and the cover 184 is connected to the base 183. Along the width direction of the frame 11, the base 183 is located between the wheel braking mechanism 171 and the cover 184. The connecting structure 185 is a hollow structure and is used to connect the first vent 1811 and the second vent 1812. Specifically, the first vent 1811 and the guide structure 182 are both located on the cover 184, and the second vent 1812 is located on the base 183. When the base 183 is connected to the cover 184, the first vent 1811 and the second vent 1812 are connected through the connecting structure 185.

[0042] In some embodiments, the base 183 is fixed to the hub 1311 by screws, and the cover 184 is fixed to the base 183 by screws. This arrangement allows the cover 18 to be a split structure, thereby reducing the size of the cover 18 and improving the ease of assembly of the cover 18.

[0043] More specifically, a limiting step 1841 is formed on the side of the cover 184 facing away from the airflow structure 182, and the limiting step 1841 communicates with the first vent 1811. A connecting protrusion 1831 is formed on the side of the base 183 facing the cover 184, and the connecting protrusion 1831 communicates with the second vent 1812. Both the limiting step 1841 and the connecting protrusion 1831 are hollow structures. When the base 183 is connected to the cover 184, the connecting protrusion 1831 abuts against the limiting step 1841 to form a communication structure 185. With this configuration, the connection between the limiting step 1841 and the connecting protrusion 1831 enables the communication between the first vent 1811 and the second vent 1812, thereby allowing airflow on both sides of the cover 18 and thus dissipating heat from the wheel braking mechanism 171.

[0044] It should be noted that this application does not limit the form and structure of the connecting structure 185, as long as the first vent 1811 and the second vent 1812 are connected through the connecting structure 185 when the base 183 and the cover 184 are connected.

[0045] In one implementation, multiple covers 184 are provided, evenly distributed around the wheel 131 on the base 183. Each cover 184 has a first vent 1811. Multiple second vents 1812 are provided on the base 183, each connected to a first vent 1811. This arrangement, by providing multiple first vents 1811 and second vents 1812, further improves the airflow on both sides of the cover 18, thereby further improving the heat dissipation effect on the wheel 131 braking structure and thus further improving the braking performance of the wheel 131. Furthermore, when one or more covers 184 are damaged, only the damaged cover 184 needs to be replaced, which helps reduce operating costs. In some embodiments, three covers 184 are provided.

[0046] like Figure 2As shown, in one embodiment, the wheel braking mechanism 171 includes a brake disc 1711 and a brake caliper 1712. Specifically, the brake disc 1711 is connected to the wheel hub 1311, and the brake caliper 1712 is connected to the suspension system 14. The brake caliper 1712 can brake the brake disc 1711. With this configuration, the brake caliper 1712 will generate a large amount of heat when braking the brake disc 1711. If the temperature cannot be dissipated, the brake caliper 1712 and the brake disc 1711 will become too hot, resulting in brake fade. This application improves the airflow rate of the cover 18 along both sides of the width direction of the frame 11 by opening a guide hole 181 on the cover 18, thereby facilitating the heat dissipation of the brake caliper 1712 and the brake disc 1711. More specifically, the air guide hole 181 faces the brake disc 1711 and the brake caliper 1712. This arrangement allows the air to flow towards the brake disc 1711 and the brake caliper 1712 when the air guide hole 181 guides the air, thereby further improving the heat dissipation effect of the brake disc 1711 and the brake caliper 1712, and thus improving the braking effect of the brake disc 1711 and the brake caliper 1712.

[0047] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
