Description

Technical Field

[0001] The utility model relates to the technical field of universal joints, and specifically, to an adaptive universal joint. Background Art

[0002] A universal joint, namely a universal joint, is a mechanical part that realizes power transmission at a variable angle and is used in positions where the direction of the transmission axis needs to be changed. It is the "joint" part of the universal transmission device in the vehicle drive system. The combination of a universal joint and a transmission shaft is called a universal joint transmission device;

[0003] In the process of using the existing universal joint, it usually plays a role in realizing power transmission at a variable angle. However, in actual use, due to the lack of weather resistance function, it is easy to break when used for a long time in areas with large temperature differences between day and night. In this way, the universal joint cannot be used, which brings trouble to the staff. Therefore, we propose an adaptive universal joint. Summary of the Utility Model
