Embodiment Construction
[0013] see Figure 5 The locking structure of the wheel lock nut and the drive shaft proposed by the present invention mainly improves the structure of the lock nut 9 . The outer peripheral surface of the wheel locknut is designed to be divided into three sections by three steps, the bottom section is a disc washer end 91, the middle section is a polygonal cylindrical body 92, and the upper section is a locking edge 93 . Correspondingly, the drive shaft 4 also needs to be improved a bit, and a section of inclined groove 41 is cut on the outer peripheral surface of the drive shaft 4 near the end.
[0014] see image 3 and Figure 4 , in the assembly process, assemble the lock nut 9 on the drive shaft 4, when the torque required for lock is reached, just knock down the lock nut edge 93 until it is in contact with the drive shaft 4 The chute 41 is close to each other, so that the knocked-off locking edge 93 cooperates with the chute 93 at the end of the drive shaft, so that t...
