[0010] Beneficial effects

[0011] Compared with the prior art, this utility model has the following advantages:

[0012] This utility model discloses a highly integrated gear chamber structure that integrates mounting bases for multiple components, such as bearing bushings, idler gear shafts, water pumps, fuel injection pumps, oil pumps, and shock absorber covers, onto the gear chamber body. This diversifies the functions of the gear chamber, optimizes the engine layout space, and integrates the engine's cooling and lubrication pipes inside the gear chamber body, shortening the length of related pipes and effectively improving cooling and lubrication efficiency. This results in a more compact and aesthetically pleasing overall layout. By incorporating a bushing mounting section, the bushing can support the front end of the crankshaft, reducing crankshaft bending deformation and significantly improving the overall operational stability.
