[0002] The automatic transmission cable of the automobile is the main transmission mechanism for people and vehicles to shift gears and torque. The counterweight on the automatic transmission cable is mainly to balance the cable and prevent and reduce the resonance vibration during the operation of the car. The counterweight is usually made of metal materials (such as aluminum alloy, etc.), the process is complicated, and the installation and connection use screws, which is time-consuming and laborious, and the cost of materials is high. In recent years, new non-metallic materials (such as rubber, etc.) have been selected in the industry to make counterweights. The process is simple, and the material cost is greatly reduced, but the friction coefficient of the non-metallic rubber and other counterweights is large, and when assembling with the cable, the interference friction must be increased to ensure that the assembly meets the requirements. The pull-off force is high, so that it will not slip due to insufficient friction due to small interference, but large interference leads to large friction, making it extremely difficult to wear, difficult to mass produce, and very difficult to promote, which limits industrial applications.

[0003] Due to the above reasons and the lack of longitudinal rigidity of the cable, it is difficult to overcome the friction between the rubber weight and the cable during the threading process. There is no feasible method and the threading machine can directly thread the cable into the rubber weight. At present, the rubber counterweight is often heated and softened first, or the air pressure is used to expand it at the same time, and then forced to wear it by hand. During the operation, not only the energy consumption is high, but the air pressure noise of the opening and closing is large. Decomposition and release of polluting gases at high temperature will directly harm the health of the workers. The labor intensity is high, the efficiency is low, the scrap rate is high, and it is difficult to meet the requirements of mass production.
