The invention relates to a high-strength wheel spoke which comprises a bar, a threaded portion at one end of the bar, a bending portion at the other end of the bar, a diameter enlarging portion between a neck and a bar cap and a diameter enlarging portion between the neck and the bending portion. A bar diameter enlarging portion is arranged on the joint part of the bar and the bending portion, reducing joint portions are arranged between a neck diameter enlarging portion and a bar cap and between the bar diameter enlarging portion and the bar. According to the high-strength wheel spoke, the practical problem that the joint part of the bar and the bending portion is worn most obviously and is prone to being broken in the using process of the spoke, the diameter enlarging portion is arranged on the joint part and remarkably reduces the phenomenon that breaking is caused easily due to the fact that the part is worn most obviously, and the tension intensity of the high-strength wheel spoke is obviously better than common hard steel spokes of the same specification. The high-strength wheel spoke is obtained through a die stamping method, and the bar cap and all the diameter enlarging portions are formed at the same time through stamping of two sets of dies. The high-strength wheel spoke has the advantages that the intensity of the spoke is improved remarkably.
