The invention discloses an electric vehicle driving shaft and hub connecting structure which comprises a driving shaft handle (1) and a hub (2), the hub (2) is installed on the driving shaft handle (1), the driving shaft handle (1) is sleeved with an expansion cone (3), the inner wall of the expansion cone (3) is in friction connection with the outer wall of the driving shaft handle (1), and the inner wall of the expansion cone (3) is in friction connection with the outer wall of the driving shaft handle (1). The outer wall of the expansion cone (3) is in friction connection with the inner wall of a mounting hole in the hub (2), one end of the driving shaft handle (1) is provided with a mounting surface (4), and the other end of the driving shaft handle (1) is provided with a self-locking nut (5). The problems that abnormal sound is generated when the torque is increased suddenly and the hub nut is prone to loosening can be solved.
