Problems solved by technology

[0005] Moreover, the tooth height of the above-mentioned traditional tooth pattern is designed to be equal from the front tooth to the end tooth. In the process of manual wheel assembly or automatic wheel assembly, it will happen that the spoke cap is not easy to lock in, and the production speed will be greatly reduced. Especially in today when the production efficiency is highly valued, it is necessary to improve the tooth structure of the spokes

Embodiment Construction

[0028] The present invention provides a method for improving the structure of the spoke teeth of bicycles and locomotives. The method uses mechanical processing to increase the structural strength of the teeth 11 of the spoke body 1 and improve its shape; image 3 As shown, it is the spoke body structure 1 comprising the elbow 10 and the reinforced tooth 11 structure made by the method of the present invention; now the preferred embodiments are listed, and then the present invention is fully described:

[0029] First, for an introduction to the method, see Figure 3 ~ Figure 5 As shown, the equipment used at least includes clamping die 2, punching die 3, dental machine 4, etc., and the steps are as follows:

[0030] A. Utilize the upper and lower clamping dies 20 and 21 of the clamping die 2 to clamp the wire 5, and make the punching die 3 approach the clamping die 2 forward;

[0031] B. The inner mold 30 of the punching die 3 contacts the clamping die 2, and the striker 31 in...

Abstract

The present invention provides a method for improving bicycle and moped wheel spoke tooth portion structure. It is mainly characterized by that it adopts stamping mode of machining operation to make tooth portion be formed and change the diameter of spoke tooth portion, so that it can make the diameter of tooth bottom of the spoke tooth portion be greater than or equal to diameter of spoke self-body. Besides, said invention also provides the concrete structure of said improved spoke tooth portion and its concrete form, said improved spoke tooth portion structure can greately raise the strength of the spoke.

Description

technical field [0001] The invention relates to a technique for improving the structure of the spoke teeth. In other words, it refers to a processing method that can increase the fatigue resistance design of the spoke teeth; it is mainly to change the tooth diameter of the spoke teeth, so as to improve the structure combined with the spoke cap, and at the same time, due to the increase of the cross-sectional area of ​​the tooth bottom, overcome the spoke Insufficient fatigue resistance in this area. Background technique [0002] As far as the structural strength and fatigue resistance of the spoke are concerned, the neck has the lowest tensile capacity due to shear force, and the bending part has the worst fatigue resistance due to vibration; therefore, most of the fractures are in the elbow. The tooth part of the traditional spoke, the tooth bottom diameter ψB<ψA, and the end tooth is the limit point of the spoke cap locking, even if the spoke does not reach the The te...
