Description

Technical Field

[0001] The utility model relates to the technical field of automobile gear boxes, in particular to a gear box with an assembled structure. Background Art

[0002] Automobile gearboxes have a wide range of applications. For example, they are used in automobiles to change the speed of the car and the torque on the car's drive wheels within a large range. The main application is the speed reduction principle of gear transmission. Simply put, there are multiple sets of gear pairs with different transmission ratios in the gearbox, and the shifting behavior when the car is driving, that is, the different gear pairs in the gearbox are operated through the operating mechanism. For example, at low speed, the gear pair with a large transmission ratio is operated, and at high speed, the gear pair with a small transmission ratio is operated. Therefore, the gearbox is also called a gearbox.

[0003] The existing patent with publication number CN215334335U proposes a gear box with an assembled structure. The gear box is provided with a supporting structure and a sealing structure, and the sealing structure can be detachably mounted on the supporting structure. The utility model relates to the technical field of gear boxes. Through the supporting structure, the overall disassembly and assembly are convenient, and the internal engine oil can be stored and processed, so that the installation of the bottom support of the gear box is faster and more convenient, and it is easy to disassemble, inspect and repair, which facilitates the installation of the gear box and is more convenient to assemble during use.

[0004] Although the gearbox is fixed with multiple bolts for easy disassembly, the surface of the bolts is prone to rust and corrosion over time, and it is relatively difficult for workers to disassemble it using tools, which increases the burden on the workers, is time-consuming and labor-intensive, and is not convenient for quick disassembly and assembly. In response to the above problems, we propose an improved and upgraded gearbox with an assembled structure. Utility Model Content
