[0031] The following is combined with Figure 1-3 The present application is further described in detail to make the technical solution of the present application easier to understand and grasp.

[0032] The embodiment of the present application discloses a Y-shaped motorcycle engine hanger.

[0033] Reference Figure 1-Figure 3 The present embodiment provides a Y-shaped motorcycle engine hanger, comprising a hanger body 1, with a first mounting end 2 and a second mounting end 3 fixedly connected at each end. Two limiting portions 21 are fixedly connected to the side of the first mounting end 2 away from the second mounting end 3. The two limiting portions 21 are each provided with a first through-hole 24, and the two first through-holes 24 are coaxially arranged. When the engine is mounted on the hanger body 1, the opposing side surfaces of the two limiting portions 21 abut against the engine mounting position. The second mounting end 3 is provided with a plurality of second through-holes 32. A mating portion 31 is provided on the second mounting end 3, with a smooth, rounded transition between the mating portion 31 and the hanger body 1. When the hanger is mounted on the vehicle frame, the mating portion 31 abuts against the engine mounting position.

[0034] Reference Figure 1-Figure 3 During the engine assembly process, the engine installation position only needs to be placed between the two limiting portions 21 of the second mounting end 3 to limit and position the engine installation, and then bolts and nuts are simultaneously penetrated through the engine and the two first through-holes 24 to secure the engine. This reduces the number of parts and assembly links, improves the structural integrity and strength of the hanger body 1, reduces problems caused by assembly tolerances, and simplifies the installation process, reducing the difficulty of installing the motorcycle engine hanger. At the same time, during the assembly process of the hanger and the frame, the matching portion 31 is aligned with the installation position on the frame, and the second through-holes 32 on the frame and the second mounting end 3 are penetrated by the mounting bolts to secure the hanger to the frame, facilitating installation and disassembly. At the same time, the connection strength between the hanger and the frame is ensured, so that the power of the engine can be effectively transmitted to the frame.

[0035] Reference Figure 1-Figure 3 The two limiting portions 21 are each fixedly connected to a connecting portion 22. The ends of the two connecting portions 22 farther from the limiting portion 21 are fixedly connected to the second mounting end 3. The distance between the two connecting portions 22 and the other limiting portion 21 gradually decreases from the end closer to the limiting portion 21 to the end closer to the second mounting end 3. Even though the overall shape is "Y," with the first mounting end 2 forming two branches, the hanger body 1 can be connected to the engine at two different locations, making the connection more stable and distributing the stress generated during engine operation, ensuring the stability of the engine on the vehicle frame.

[0036] Reference Figure 2 The two connecting portions 22 are arranged in a gradually expanding shape from one end near the stopper 21 to the end near the second mounting end 3. This increases the stability of the structure, provides a larger support area, and disperses the load transmitted from the first mounting end 2, thereby improving the seismic resistance of the hanger body 1 and reducing the possibility of deformation or breakage of the connecting portions 22 caused by the weight and vibration of the engine.

[0037] Reference Figure 1 and Figure 2 , reinforcing ribs 23 are fixedly connected to the side surfaces of the two connecting parts 22 on opposite sides. The overall strength of the structure is enhanced, the possibility of deformation or damage of the connecting parts 22 on both sides is reduced, thereby reducing the problems caused by assembly tolerances during the installation process and reducing the difficulty of installing the motorcycle engine hanger. A V-shaped groove 231 is provided on the end of the reinforcing rib 23 close to the limit, and the opposite side surfaces of the V-shaped groove 231 are respectively tangential to the opposite side surfaces of the two limiting parts 21. When the limiting parts 21 on both sides are subjected to external force, the presence of the V-shaped groove 231 can change the direction of stress flow, making the stress distribution on the hanger body 1 more uniform, avoiding the possibility of stress concentration in a specific area, and thus reducing the possibility of fracture or damage to the structure.

[0038] Reference Figure 1 and Figure 3 A positioning edge 4 is fixedly connected to the side of the hanger body 1. The positioning edge 4 on the side of the hanger body 1 can position and limit the hanger body 1 during installation, and also serves as a foolproof function, reducing the possibility of reverse installation of the hanger body 1. This makes the installation process more convenient and reduces the difficulty of installing the motorcycle engine hanger. The positioning edge 4 can serve as a parting surface when the hanger body 1 is cast, thereby reducing the difficulty of casting the hanger body 1.

[0039] Of course, the above are only typical examples of the present application. In addition, the present application may have many other specific implementation methods. Any technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present application.
