Embodiment Construction

[0025] Further illustrate the present invention below in conjunction with embodiment and accompanying drawing.

[0026] Such as figure 1 The first embodiment, a high-strength wheel spoke, includes a bar 1, a threaded part at one end of the bar, a bent part at the other end of the bar, a neck and a cap 5, and the present invention is provided on the neck of the spoke The neck diameter increasing part 3 and the bending part are provided with the bending part diameter increasing part 2, and the bar diameter increasing part 1-1 is also provided at the junction of the bar 1 and the bending part, and the neck diameter increasing part Between the large part 3 and the bar cap 5, between the bar diameter increasing part 1-1 and the bar 1, there are respectively provided with a diameter reducing joining part 5, the bar diameter increasing part 1-1, the neck diameter increasing part 3 is smoothly connected with the surface of the bent part diameter increasing part 2.

Abstract

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.

Description

technical field [0001] The invention belongs to bicycle spokes, in particular to a high-strength wheel spoke. Background technique [0002] The spoke is composed of a bar, a threaded part at one end of the bar, a bent part and a cap at the other end of the bar, and the spokes are widely used in spoked wheels such as bicycles, motorcycles, and tricycles. [0003] The current bicycle spoke standard divides spokes into ordinary spokes and special-shaped spokes. There are four kinds of ordinary spoke specifications: №12, 13, 14, and 15. In the standard, the spoke materials, the dimensions of each part of the spokes of various specifications, and the cutting strength are specified. Clearly defined. [0004] Usually, the choice of spoke specifications is determined based on comprehensive consideration of vehicle type, maximum bearing capacity and safety factor. [0005] However, the spoked wheels of the above-mentioned various vehicle types often have broken bars during use, esp...
