Description

Technical Field

[0001] The utility model relates to the technical field of mechanical assembly, in particular to an active bevel gear flange assembly. Background Art

[0002] The flange assembly generally refers to the parts that connect the two ends of the automobile drive shaft to the wheels, which are used to transmit power and torque and allow the wheels to turn during the movement of the suspension system. The flange assembly needs to be installed with a dust cover to block dust, etc. during assembly. However, the existing technology is to directly weld the dust cover to the flange assembly. The high temperature during welding can easily deform the dust cover, and if the dust cover is damaged, it cannot be replaced. Therefore, those skilled in the art provide an active bevel gear flange assembly to solve the problems raised in the above background technology. Utility Model Content
