Description

Technical Field

[0001] The utility model relates to the technical field of components for supporting motorcycle engines, in particular to a flange bracket structure of a motorcycle engine. Background Art

[0002] Currently, the engines of traditional straddle-type motorcycles are either directly fixed to the frame or directly mounted to the engine via frame fittings. After the frame fittings are installed, the lower middle and bottom portions of the engine are suspended in the air, meaning they are not supported by any brackets or supports. Typically, the engine and frame fittings are fixed together using locking bolts. Because the engine and frame fittings are directly connected, vibrations during operation can cause resonance, which can easily cause the locking bolts to deform and loosen, reducing engine stability. Furthermore, when large-displacement engines are installed on motorcycles, resonance can also cause cracks in the frame fittings, significantly increasing the probability of accidents.

[0003] Without flanges, deformation is likely to occur when tightening the bolts, thus affecting the strength of the bracket. When installing a large-displacement engine, resonance may cause cracks in the bracket, greatly increasing the probability of accidents.

[0004] In the prior art, Chinese Patent No. 202321024363.X discloses a patented "off-road motorcycle frame," which describes a "mounting plate 3 detachably fixedly connected to the bottom end of the vertical arm frame tube 12, with the engine fixedly connected to the mounting plate 3." Another Chinese Patent No. 202323343773.3 discloses a "new type of motorcycle engine bracket." The engine bracket in this patent separately connects and fixes the motorcycle engine and frame, and is equipped with a shock-absorbing ring to enhance shock absorption, reduce vibration-induced collisions and friction between frame parts, and prevent loosening and wear of motorcycle components.

[0005] Although the patented technical solutions of the above two existing patent documents realize the connection between the engine and the frame and provide stability for the engine operation by adding a mounting plate or a motorcycle engine bracket, in actual use, the above patented technical solutions still have some shortcomings, specifically as follows: the mounting plate or the engine bracket are both made of a single thin metal plate by stamping and bending, and there are no corresponding reinforcing ribs or flanges or reinforcing support plates in the structure to improve the strength; when the strength is not strong enough, the bolts installed between the mounting plate or the engine bracket and the engine will easily deform, thereby affecting the strength of the entire engine bracket, and when installing a large-displacement engine, the resonance is particularly obvious and serious, and a larger resonance may cause cracks in the engine bracket, greatly increasing the probability of accidents.

[0006] Therefore, it is necessary to make certain improvements to the structures such as the bracket or mounting plate of the motorcycle engine in the prior art to improve the problems of the prior art, so as to develop an engine bracket structure that can improve the overall strength, is not easy to deform and makes the engine work more stably. Summary of the Invention

[0007] The purpose of the utility model is to overcome the shortcomings of the above-mentioned prior art and provide a flange bracket structure for a motorcycle engine. The flange bracket structure of the motorcycle engine is designed with two sections, namely a frame flange bracket member connected to the frame and an engine flange bracket member connected to the engine. Both the frame flange bracket member and the engine flange bracket member are provided with an outward-flanged outer flange structure on the inner side. The setting of the outer flange can improve the strength of the overall flange bracket structure, and it is not easy to deform and tear. When it is connected and installed with a large-displacement engine, it also makes the engine more stable, improves the working stability of the engine, extends the service life of the engine, and reduces the probability of accidents. In addition, a thicker reinforced connection recess is added between the frame flange bracket and the engine flange bracket, which strengthens the connection between the two parts, improves the rigidity of the connection between the two parts, and ensures that deformation and tearing will not occur, thereby ensuring normal operation and extending service life; finally, since the engine will generate a lot of heat when working, and the flange bracket structure will cover part of the outside of the engine, by setting heat dissipation holes with larger apertures on the flange bracket structure, the heat on the outside of the engine can be quickly dissipated, achieving the effect of rapid heat dissipation of the engine and ensuring the normal operation of the engine.

[0009] Furthermore, the engine flange bracket is tightly sleeved on the lower and middle part of the outer side of the engine, and the outer flange on the engine flange bracket is arranged on an inner side of the engine flange bracket. The outer flange of the engine is an arc-shaped outer flange that matches the outer shape of the engine. The other inner side of the engine flange bracket is provided with an arc-shaped recessed notch that is recessed inward and matches the outer shape of the engine.

[0010] Furthermore, the frame flanging bracket is connected and installed with the frame pipe on the frame, and the lower middle part of the frame pipe is embedded in the frame flanging bracket; the frame outer flanging is an inclined linear outer flanging that is inclined.

[0011] Furthermore, the engine outer flange and the frame outer flange are both right-angled flanges that form a 90-degree right angle outward.

[0012] Furthermore, a rounded outer flange is provided on the outer side of the reinforced connection recess and is integrally connected with the outer flange of the frame.

[0013] Furthermore, the frame flange bracket is provided with a frame flange bracket mounting hole corresponding to the frame mounting hole on the frame tube; the engine flange bracket is provided with an engine flange bracket mounting hole corresponding to the engine mounting hole on the engine; the frame mounting hole and the frame flange bracket mounting hole, and the engine mounting hole and the engine flange bracket mounting hole are fixedly connected by bolts.

[0014] To sum up, the flange bracket structure of the motorcycle engine of the present invention is divided into two designs, namely a frame flange bracket component connected to the frame and an engine flange bracket component connected to the engine. Both the frame flange bracket component and the engine flange bracket component are provided with an outward-flanged outer flange structure on the inner side.

[0025] Example 1

[0026] The flange bracket structure of a motorcycle engine described in this embodiment 1 is as follows: Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 and Figure 9As shown, it includes a flange bracket 3 installed and connected to the frame 1 and the engine 2; the flange bracket includes a frame flange bracket member 4 fixedly installed with the frame, and an engine flange bracket member 5 fixedly installed with the engine and integrally formed with the frame flange bracket member; the inner sides of the frame flange bracket member and the engine flange bracket member are respectively provided with a frame outer flange 6 and an engine outer flange 7 outwardly; a reinforced connection recess 8 that is inwardly recessed and has an increased thickness is also provided between the connection positions of the frame flange bracket member and the engine flange bracket member; the engine flange bracket member is also provided with a heat dissipation through-hole 9 that communicates with the outside of the engine. The flange bracket is composed of two parts formed by integral stamping and bending, namely a frame flange bracket part and an engine flange bracket part. The frame flange bracket part is fixedly connected and installed with the frame, and the engine flange bracket part is fixedly connected and installed with the outer side of the engine. External flanges are provided on the inner sides of the frame flange bracket part and the engine flange bracket part which are matched with the corresponding frame and engine. The external flanges can improve the strength and thickness of the outer side of the flange bracket, thereby improving the strength of the entire flange bracket. When the engine is installed, the entire flange bracket is not easy to deform or tear, thereby improving the performance of the flange bracket in supporting the engine and making the engine work more stably. The reinforced connection recess provided between the connection position of the frame flange bracket and the engine flange bracket is a connection transition portion with a thicker thickness, which can enhance the thickness of the frame flange bracket between the engine flange bracket, improve the strength of the connection, etc., thereby achieving strong rigidity of the connection and ensuring that the connection between the frame flange bracket and the engine flange bracket will not be easily deformed or torn; in addition, the heat dissipation holes provided on the engine flange bracket can quickly discharge the heat dissipated from the engine in time, cool the engine in time, and ensure the normal operation of the engine.

[0027] In this embodiment 1, the engine flange bracket is tightly mounted on the lower middle part of the outer side of the engine, and the outer flange on the engine flange bracket is arranged on an inner side of the engine flange bracket. The outer flange of the engine is an arc-shaped outer flange that matches the outer shape of the engine. The other inner side of the engine flange bracket is provided with an arc-shaped recessed notch 10 that is recessed inward and matches the outer shape of the engine. The engine flange bracket is only provided with an engine outer flange on one inner side, and no engine outer flange is provided on the other inner side; the engine flange bracket is irregular in shape, and the two sides are asymmetrical and have a certain curvature. The engine flange bracket is a frame-shaped structure and covers part of the side surface of the engine when it is installed and connected to the outer side of the engine. The width of the engine flange bracket is greater than the width of the frame flange bracket; the engine outer flange is designed to be an arc-shaped outer flange, which can be well adapted to the installation of the outer outer mounting end face of the engine, so that the two are compact after installation, without extra gap space, etc., making the installation match more firm; similarly, the arc-shaped recessed notch provided on the other inner side of the engine flange bracket is also for more compact installation match with the outer outer mounting end face of the engine, and also achieves the purpose of more firm and stable installation match between the two.

[0028] In this first embodiment, the frame flange bracket is connected and mounted to the frame tube 11 on the vehicle frame, with the lower and middle portions of the frame tube embedded in the frame flange bracket. The frame outer flange is an inclined linear outer flange. The vehicle frame is connected to the frame flange bracket via the frame tube (a round steel tube). During installation, the lower and middle portions of the frame tube are embedded in the frame flange bracket. The frame flange bracket is a frame-like structure with an irregular trapezoidal shape, and the frame outer flange is arranged on the inner edge of the frame flange bracket and is an inclined linear outer flange.

[0029] In this first embodiment, the engine and frame flanges are both right-angled flanges that are turned outward to form a 90-degree right angle. The 90-degree right-angle flanges allow the bent contact surfaces of the flanges to contact the mounting end surfaces of the engine's outer profile, forming a relatively flat contact surface. This allows for more accurate positioning and installation, making positioning easier and more convenient during installation.

[0030] In this embodiment 1, the outer side of the reinforced connection recess is provided with a rounded outer flange 12 that is integrally connected to the outer flange of the frame. Since this reinforced connection recess is provided to enhance strength, the rounded outer flange provided in the reinforced connection recess is an extension of the outer flange of the frame and is integrally connected without interruption, thereby also achieving the effect of enhancing the strength of the reinforced connection recess.

[0031] In this first embodiment, the frame flange bracket is provided with frame flange bracket mounting holes 14 that correspond to and mate with frame mounting holes 13 on the frame tube; the engine flange bracket is provided with engine flange bracket mounting holes 16 that correspond to and mate with engine mounting holes 15 on the engine; and bolts 17 securely connect the frame mounting holes to the frame flange bracket mounting holes, and the engine mounting holes to the engine flange bracket mounting holes. When the frame flange bracket and the engine flange bracket are mounted to the frame and engine, respectively, the corresponding mounting holes mate with each other and are tightened with bolts to form a secure connection, providing convenient, fast, and stable installation.

[0032] In this embodiment 1, the flange bracket structure of the motorcycle engine is designed in two sections, namely a frame flange bracket member connected to the frame and an engine flange bracket member connected to the engine. Both the frame flange bracket member and the engine flange bracket member are provided with an outward-flanged outer flange structure on the inner side. The setting of the outer flange can improve the strength of the overall flange bracket structure, making it less prone to deformation and tearing. When connected and installed with a large-displacement engine, it also makes the engine more stable, improves the engine's working stability, extends the engine's service life, and reduces the probability of accidents. In addition, a thicker reinforced connection recess is added between the frame flange bracket and the engine flange bracket, which strengthens the connection between the two parts, improves the rigidity of the connection between the two parts, and ensures that deformation and tearing will not occur, thereby ensuring normal operation and extending service life; finally, since the engine will generate a lot of heat when working, and the flange bracket structure will cover part of the outside of the engine, by setting heat dissipation holes with larger apertures on the flange bracket structure, the heat on the outside of the engine can be quickly dissipated, achieving the effect of rapid heat dissipation of the engine and ensuring the normal operation of the engine.

[0033] The above description is only a preferred embodiment of the present invention and does not constitute any formal limitation on the structure of the present invention. Any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention shall still fall within the scope of the technical solution of the present invention.
