Detailed ways

The core of the present invention is to provide an engine hanger structure and a motorcycle, which are simple in structure, easy to install, and have an optimized assembly process.

In order to make those skilled in the art better understand the technical solutions provided by the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

Please refer to FIG. 1 to FIG. 2 , the present invention provides an engine hanger structure. The engine hanger structure 3 is an integrally formed structure with a “Y” shape as a whole. The engine hanger structure 3 includes a A first end and two second ends for connection with the engine 1 . The two second ends form two branches, which are respectively connected to the frame 2, so as to achieve the stability of the connection.

Compared with the traditional iron hanger or the technical solution directly assembled to the frame, the structure of the engine hanger provided by this solution improves the structural strength through the integrated molding structure design, and has a simple "Y"-shaped structure as a whole. , the engine installation is simple and easy to install, and the assembly process has been optimized.

In a specific embodiment, the first end of the engine hanger structure 3 and the vehicle frame 2 are provided with bolt holes at positions opposite to each other, and the first end of the engine hanger structure 3 and the vehicle frame 2 are connected by mounting bolts. The engine hanger structure 3 is fixed on the frame by bolts, and the detachable principle is fully utilized to make the engine installation simple and easy to operate. Specifically, as shown in FIG. 2 , the mounting bolts include at least two first mounting bolts 401 , and the first mounting bolts 401 are M8 bolts.

Both the second end of the engine hanger structure 3 and the engine 1 are provided with bolt holes, and the second end of the engine hanger structure 3 is connected with the engine 1 by mounting bolts. The engine 1 is provided with mounting holes, which are connected by second mounting bolts 402 . The second mounting bolts 402 are M10 bolts.
