Description

Technical Field

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

[0002] Motorcycles are a common and widely used mode of transportation, comprising a frame, running gear, power system, and suspension system. The power system includes the engine, which provides power for the motorcycle's operation. Currently, the engine and intake manifold of motorcycles are typically connected by a rubber hose. During engine operation, relative vibrations occur between the engine and the intake manifold. These vibrations can cause the rubber hose to loosen from the engine intake, resulting in poor connection stability. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, the purpose of this application is to provide a motorcycle with a high degree of stability in the connection between the rubber sleeve and the air intake.

[0004] To achieve the above objectives, this application adopts the following technical solution:

[0005] A motorcycle includes a frame, a body panel, a running system, and a power system. The body panel at least partially covers the frame, the running system is at least partially located below the frame, and the power system includes an engine supported by the frame and providing power to the running system. The engine has an air intake section with an air inlet. The power system includes an air intake assembly connected to the air intake section. The air intake assembly includes a rigid tube, a rubber sleeve, and a first clamp. One end of the rubber sleeve is fitted around the outer periphery of the air intake section, the rigid tube is embedded inside the rubber sleeve, and one end of the rigid tube is connected to the air inlet. The first clamp is tightened around the outer periphery of the rubber sleeve. A portion of the first clamp is located around the outer periphery of the air intake section and abuts the air intake section against the rubber sleeve radially. The other portion of the first clamp is located around the outer periphery of the rigid tube and abuts the rigid tube against the rubber sleeve radially.

[0006] Furthermore, a first protrusion is provided on the outer peripheral wall of one end of the rubber sleeve near the air intake. Part of the first protrusion is located on the outer periphery of the air intake, and the other part of the first protrusion is located on the outer periphery of the rigid tube.

[0007] Furthermore, the first protrusion has an annular structure, with part of the first protrusion surrounding the outer periphery of the air intake and another part surrounding the outer periphery of the rigid tube.

[0008] Furthermore, along the direction from the air intake to the rigid pipe, the outer diameter of the first protrusion gradually decreases, and the first clamp is tightened around the outer periphery of the first protrusion. When viewed from the axial direction of the rubber sleeve, the first clamp and the first protrusion at least partially overlap.

[0009] Furthermore, the power system also includes an intake pipe, which is connected to the intake section through an intake assembly. The intake assembly also includes a second clamp, with the other end of a rubber sleeve fitted around the outer periphery of the intake pipe and the other end of a rigid pipe connected to the inlet of the intake pipe. The second clamp is tightened around the outer periphery of the rubber sleeve, with a portion of the second clamp located around the outer periphery of the intake pipe and pressing the intake pipe against the rubber sleeve along the radial direction of the rubber sleeve. The other portion of the second clamp is located around the outer periphery of the rigid pipe and presses the rigid pipe against the rubber sleeve along the radial direction of the rubber sleeve.

[0010] Furthermore, a second protrusion is provided on the outer peripheral wall of the end of the rubber sleeve near the intake pipe. Part of the second protrusion is located on the outer periphery of the intake pipe, and the other part of the second protrusion is located on the outer periphery of the rigid pipe.

[0011] Furthermore, the second protrusion has an annular structure, with part of the second protrusion surrounding the outer periphery of the intake pipe and another part surrounding the outer periphery of the rigid pipe.

[0012] Furthermore, along the direction from the intake pipe to the rigid pipe, the outer diameter of the second protrusion gradually decreases, and the second clamp is tightened around the outer periphery of the second protrusion. When viewed from the axial direction of the rubber sleeve, the second clamp and the second protrusion at least partially overlap.

[0013] Furthermore, the inner diameter of the intake pipe opening is basically the same as that of the rigid pipe opening, and the center line of the intake pipe opening basically coincides with the center line of the rigid pipe opening.

[0014] Furthermore, the inner diameter of the air inlet and the opening of the rigid pipe are basically the same, and the center line of the air inlet and the center line of the opening of the rigid pipe are basically coincident.

[0015] The aforementioned motorcycle has a rubber sleeve fitted around the outer periphery of the air intake, with a rigid tube embedded inside the rubber sleeve and one end of the rigid tube connected to the air intake. This fixes the relative position of the rigid tube and the rubber sleeve, preventing the rigid tube from shifting within the rubber sleeve and improving the connection stability between the rigid tube and the air intake.

[0022] 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.

[0023] Motorcycles include street bikes, touring bikes, and off-road bikes.

[0024] like Figure 1 As shown, this application provides a motorcycle 100, which is described using an off-road motorcycle as an example.

[0025] The motorcycle 100 includes a frame 11, a body panel 12, a running system 13, and a power system 14.

[0026] For ease of expression, the definitions in this application are as follows: Figure 1 The directions shown are front, back, left, right, up, and down. The front-back direction refers to the length of the motorcycle frame 11, the left-right direction refers to the width of the motorcycle frame 11, and the up-down direction refers to the height of the motorcycle frame 11. In this embodiment, the front, back, left, right, up, and down directions are based on the motorcycle 100 traveling on a level surface, not on a sloping surface.

[0027] The frame 11 serves as the basic framework of the motorcycle 100, supporting the body panel 12, the running gear 13, and the power system 14. The body panel 12 at least partially covers and connects to the frame 11, thereby protecting the internal components of the motorcycle 100. The running gear 13 is at least partially located beneath the frame 11.

[0028] Specifically, the running gear 13 includes a front wheel 131 and a rear wheel 132. The frame 11 includes a front frame 111 and a rear frame 112 fixedly connected together. The front wheel 131 is connected to the front frame 111, and the rear wheel 132 is connected to the rear frame 112. The front wheel 131 is at least partially located below the front frame 111, and the rear wheel 132 is at least partially located below the rear frame 112. More specifically, a front suspension is connected to the front frame 111, and the front wheel 131 is connected to the front frame 111 via the front suspension. A rear suspension is connected to the rear frame 112, and the rear wheel 132 is connected to the rear frame 112 via the rear suspension.

[0029] The body panel 12 at least partially covers the front frame 111 and the rear frame 112.

[0030] The power system 14 is supported by the front frame 111 and provides power to the running gear 13. The power system 14 can be connected to the front wheel 131 or to both the front wheel 131 and the rear wheel 132.

[0031] like Figure 2 As shown, in one embodiment, the power system 14 includes an intake assembly 25. The engine 141 is provided with an intake section 1412, which has an intake port 1412a. The intake section 1412 is connected to the intake assembly 25, so that the intake assembly 25 can deliver outside air to the engine 141.

[0032] like Figure 2 , Figure 3 and Figure 4 As shown, the intake assembly 25 includes a rigid tube 251, a rubber sleeve 252, and a first clamp 253. One end of the rubber sleeve 252 is fitted around the outer periphery of the intake section 1412, and the rigid tube 251 is embedded inside the rubber sleeve 252, with one end of the rigid tube 251 connected to the intake port 1412a. The first clamp 253 is tightened around the outer periphery of the rubber sleeve 252. A portion of the first clamp 253 is located around the outer periphery of the intake section 1412, and along the radial direction of the rubber sleeve 252, it presses the intake section 1412 against the rubber sleeve 252. The other portion of the first clamp 253 is located around the outer periphery of the rigid tube 251, and along the radial direction of the rubber sleeve 252, it presses the rigid tube 251 against the rubber sleeve 252. As an optional implementation, the rigid tube 251 can be a metal tube.

[0033] It should be noted that the connection means that the air intake 1412a is aligned and abuts against the opening of the rigid pipe 251, so that the outside air flows more smoothly through the connection between the air intake 1412a and the rigid pipe 251, thereby improving the stability of the air flowing into the engine 141.

[0034] Because the rubber sleeve 252 is elastic, it can undergo elastic deformation when the engine 141 vibrates, thereby improving the vibration tolerance of the intake assembly 25 and extending its service life. Furthermore, the rigid tube 251 inside the rubber sleeve 252 increases its rigidity, which in turn enhances the structural strength of the intake assembly 25. Thus, while improving the vibration tolerance, the structural strength of the intake assembly 25 is also enhanced.

[0035] Furthermore, the first clamp 253 can improve the tightness of the connection between the air intake 1412 and the rubber sleeve 252, thereby preventing air leakage caused by gaps at the connection between the air intake 1412 and the rubber sleeve 252. At the same time, the first clamp 253 can also fix the relative position of the rigid tube 251 and the rubber sleeve 252, thereby preventing the rigid tube 251 from shifting within the rubber sleeve 252, which helps to improve the connection stability between the rigid tube 251 and the air intake 1412a.

[0036] In this application, a first protrusion 2522 is provided on the outer peripheral wall of the rubber sleeve 252 near the air intake 1412. Part of the first protrusion 2522 is located on the outer periphery of the air intake 1412, and the other part of the first protrusion 2522 is located on the outer periphery of the rigid tube 251.

[0037] With the above settings, the thickness of the end of the rubber sleeve 252 near the air intake 1412 can be increased by the first protrusion 2522, so that when the first clamp 253 tightens the air intake 1412, the end of the rubber sleeve 252 near the air intake 1412 can perform greater elastic expansion and contraction, thereby improving the vibration tolerance of the rubber sleeve 252.

[0038] In this embodiment, the first protrusion 2522 is an annular structure, with a portion of the first protrusion 2522 surrounding the outer periphery of the air intake 1412 and another portion of the first protrusion 2522 surrounding the rigid tube 251.

[0039] like Figure 4 and Figure 5 As shown, along the direction from the air intake 1412 to the rigid tube 251, the outer diameter of the first protrusion 2522 gradually decreases, and the first clamp 253 is tightened around the outer periphery of the first protrusion 2522. When viewed from the axial direction of the rubber sleeve 252, the first clamp 253 and the first protrusion 2522 at least partially overlap.

[0040] With the above configuration, the first clamp 253 has a first thrust F1 along the axial direction of the rubber sleeve 252 and acting on the rubber sleeve 252. The first thrust F1 makes the rigid tube 251 tightly connected to the air inlet 1412a. It should be noted that the first clamp 253 applies a first thrust F1 perpendicular to the outer peripheral surface of the rubber sleeve 252 to the first protrusion 2522. The first thrust F1 can be decomposed into mutually perpendicular components F11 and F12. The direction of component F11 is perpendicular to the centerline of the rigid tube 251, and component F12 is parallel to the centerline of the rigid tube 251 and toward the air inlet 1412a. This allows the rubber sleeve 252 to be tightly connected to the air inlet 1412 under the action of component F12, thereby improving the stability of the connection between the air intake assembly 25 and the air inlet 1412.

[0041] like Figure 3 and Figure 4 As shown, the power system 14 also includes an intake pipe 26, which is connected to the intake section 1412 via the intake assembly 25, allowing outside air to flow into the engine 141 through the intake pipe 26, the intake assembly 25, and the intake section 1412. The rubber sleeve 252, being elastic, can undergo elastic deformation when the engine 141 vibrates, allowing relative movement between the intake pipe 26 and the intake section 1412 to buffer the forces generated by vibration. This improves the vibration tolerance of the intake assembly 25 and thus extends its service life.

[0042] Specifically, the intake assembly 25 also includes a second clamp 254. The other end of the rubber sleeve 252 is fitted around the outer periphery of the intake pipe 26, and the other end of the rigid pipe 251 is connected to the opening of the intake pipe 26. The second clamp 254 is tightened around the outer periphery of the rubber sleeve 252. A part of the second clamp 254 is located around the outer periphery of the intake pipe 26 and abuts the intake pipe 26 against the rubber sleeve 252 along the radial direction of the rubber sleeve 252. The other part of the second clamp 254 is located around the outer periphery of the rigid pipe 251 and abuts the rigid pipe 251 against the rubber sleeve 252 along the radial direction of the rubber sleeve 252.

[0043] The second clamp 254 tightens the connection between the intake pipe 26 and the rubber sleeve 252, thus preventing air leakage caused by gaps at the connection. Simultaneously, the second clamp 254, in conjunction with the first clamp 253, fixes the relative position of the rigid pipe 251 and the rubber sleeve 252, preventing the rigid pipe 251 from shifting within the rubber sleeve 252 and improving the stability of the connection between the rigid pipe 251 and the intake pipe 26.

[0044] It should be noted that the connection means that the opening of the intake pipe 26 is aligned and abuts against the opening of the rigid pipe 251, so that the outside air flows more smoothly through the connection between the intake pipe 26 and the rigid pipe 251, thereby improving the stability of the air flowing into the engine 141.

[0045] In this application, a second protrusion 2523 is provided on the outer peripheral wall of the rubber sleeve 252 near the end of the air intake pipe 26. Part of the second protrusion 2523 is located on the outer periphery of the air intake pipe 26, and the other part of the second protrusion 2523 is located on the outer periphery of the rigid pipe 251.

[0046] With the above configuration, the thickness of the end of the rubber sleeve 252 near the air intake pipe 26 can be increased by the second protrusion 2523, so that when the second clamp 254 tightens the air intake part 1412, the end of the rubber sleeve 252 near the air intake pipe 26 can perform greater elastic expansion and contraction, thereby improving the vibration tolerance of the rubber sleeve 252.

[0047] In this embodiment, the second protrusion 2523 is an annular structure, with a portion of the second protrusion 2523 surrounding the outer periphery of the intake pipe 26 and another portion of the second protrusion 2523 surrounding the rigid pipe 251.

[0048] like Figure 4 and Figure 6 As shown, along the direction from the intake pipe 26 to the rigid pipe 251, the outer diameter of the second protrusion 2523 gradually decreases. The second clamp 254 is tightened around the outer periphery of the second protrusion 2523. Viewed axially from the rubber sleeve 252, the second clamp 254 and the second protrusion 2523 at least partially overlap. With the above arrangement, the second clamp 254 has a second thrust F2 along the axial direction of the rubber sleeve 252 and acts on the rubber sleeve 252. The second thrust F2 makes the rigid pipe 251 tightly connected to the opening of the intake pipe 26.

[0049] It should be noted that the second clamp 254 applies a second thrust F2 perpendicular to the outer circumferential surface of the rubber sleeve 252 to the second protrusion 2523. The second thrust F2 can be decomposed into mutually perpendicular components F21 and F22. The direction of component F21 is perpendicular to the center line of the rigid tube 251, and component F22 is parallel to the center line of the rigid tube 251 and toward the opening of the intake pipe 26. This allows the rubber sleeve 252 to be tightly connected to the intake pipe 26 under the action of component F12, thereby improving the stability of the connection between the intake assembly 25 and the intake pipe 26.

[0050] like Figure 4As shown, the inner diameters of the air intake 1412a and the rigid pipe 251 are basically the same, and the centerline of the air intake 1412a and the centerline of the rigid pipe 251 are basically coincident. This arrangement makes the connection between the air intake 1412a and the rigid pipe 251 smoother, allowing outside air to flow more smoothly through the connection point, thereby improving the stability of the air flowing into the engine 141.

[0051] In this application, the inner diameters of the intake pipe 26 and the rigid pipe 251 are substantially the same, and the centerline of the intake pipe 26 and the centerline of the rigid pipe 251 are substantially coincident. This arrangement allows for a smoother connection between the intake pipe 26 and the rigid pipe 251, resulting in smoother airflow through the connection point and improved stability of the air flowing into the engine 141.

[0052] 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.
