[0002] The main reducer is an important part of the automobile transmission system, which plays a role in reducing the speed and increasing the torque. A reasonable speed ratio design can effectively reduce the overall size and weight of the transmission system and improve the economic performance of the automobile. However, due to the large overall weight and size of the main reducer and the variety of internal parts, it requires more manpower during the disassembly, assembly and maintenance process. Improper coordination may cause damage to the main reducer and even cause personal injury.

[0003] At present, the disassembly and assembly of the main reducer lacks special tools and equipment, and is mainly completed by manpower. In order to prevent damage to the main reducer during the disassembly process, most of them use tires and other items for buffering protection to prevent bumps. During the maintenance process, due to the irregular shape of the main reducer shell, it cannot be fixed in a certain position for a long time, so it needs manpower to fix it during operation, which poses a safety hazard and has low maintenance efficiency. During installation, it is generally supported by multiple people to install the main reducer on the drive axle. This installation method relies on manpower, has low installation efficiency, and is prone to bumps, causing damage to the main reducer and affecting working performance. At the same time, if it slips out of the hand, improper cooperation will also cause personal injury. Some repair institutions that allow conditions use hooks to assist in disassembly and assembly, but the hooks will shake during use and cannot play a role in fixing and aligning. At the same time, the overall equipment of the hook is large and has high requirements for the site.

[0004] The utility model proposes a main reducer maintenance bracket, which focuses on the field of automobile and engineering machinery maintenance and is used for the maintenance of the main reducer, especially replacing manpower during the disassembly, installation and maintenance of the main reducer, playing the role of supporting, lifting and fixing, improving the maintenance efficiency and alignment of the main reducer, and avoiding damage during the maintenance process; as a special bracket, it is small in size and has small requirements on site conditions; at the same time, it can save manpower, avoid personal injuries, and improve safety.
