Problems solved by technology
This installation method requires that the suspension point on the suspension frame and the connection point of the engine must be highly consistent, and the precision requirements are high. If there is an error between the two during the assembly process, it will be difficult to install and adjust during the assembly process.
Because the engine of the four-wheeled motorcycle is fixed on the suspension frame by using connecting bolts to directly fix it on the suspension frame, when the engine is working, the vibration of the engine is directly transmitted to the frame of the four-wheeled motorcycle, which makes the vibration and noise of the motorcycle relatively low. Big

Embodiment Construction
[0014] Referring to Figure 1, Figure 2 and Figure 3, the quadrilateral frame 2 of the suspension structure is composed of an upper frame 2-1 and a lower frame 2-2. The upper frame 2-1 is provided with openings to facilitate the placement of the engine and the installation of the engine head. One end of the two lower frames 2-2 is connected to the upper frame, extends downwards and bends, and then extends diagonally downward so that the other end is connected to the bottom of the frame. Two suspension brackets 13 are welded to the upper ends of the two lower frames, the connecting plate 3 is located between the two suspension brackets 13, the suspension shaft 9 passes through the hole of the suspension bracket 13 and the hole of the connecting plate 3, and one end of the suspension shaft 9 uses a nut Lock tightly. A shock-absorbing rubber sleeve 6 is installed in the hole of the suspension bracket 13, the shock-absorbing washer 7 is installed outside the hole of the connecting plat...

The suspensions of four wheel motor engine comprises upper and lower frames formed quadrilateral frame, two suspension brackets welded on the bracket of two lower frames, featuring in the connection plate between two suspension bracket, with the suspension shaft fastened by castle nut connecting the connection plate of the engine through the hole of the suspension bracket with damping glue casing, damping gasket outside the hole of the connection plate, lower support plate welded to the lower end of two frames, damping gasket between the upper support plate and the bottom support plate. It requires low installation precision, with convenient assembly, reduced vibration and noise.
Description
Technical field [0001] The invention relates to a mounting structure of a motorcycle engine, in particular to a suspension frame structure of a four-wheel motorcycle engine. Background technique [0002] The engine of a quad bike is usually fixed on the suspension frame of the frame. This installation method requires that the suspension point on the suspension frame and the connection point of the engine must be highly consistent, and the accuracy is high. If there is an error between the two during the assembly process, the installation and adjustment during the assembly process are difficult. Because the engine of the quad bike is fixed on the suspension frame by using connecting bolts to directly fix it on the suspension frame, when the engine is working, the vibration of the engine is directly transmitted to the frame of the quad bike, which makes the vibration and noise of the motorcycle more severe. Big. In addition, the engine is supported on the suspension frame. Because ...
