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] With reference to Fig. 1, Fig. 2 and Fig. 3, the quadrilateral frame 2 of this suspension structure is made up of upper frame 2-1 and lower frame 2-2, and upper frame 2-1 is provided with opening, so that lay the engine and be used for installing engine. head. One end of the two lower frames 2-2 is connected with the upper frame, extends downward and bends, and then extends obliquely downward so that the other end is connected with the bottom of the frame. Two suspension brackets 13 are welded on 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 is connected with a nut lock tight. The shock-absorbing rubber sleeve 6 is installed in the hole of the suspension bracket 13, and the shock-absorbing washer 7 is installed outside the hole of the connecting plate...

Abstract
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 four-wheeled motorcycle is usually fixed on the suspension bracket of the frame. This installation method requires the suspension point on the suspension frame to be highly consistent with the connection point of the engine, and requires high precision. 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. The engine is supporte...
