The invention relates to an electro-tricycle brake cable. The electro-tricycle brake cable is characterized by comprising a steel strand (1) in the center, a middle core layer (1.1) is arranged in the middle of the steel strand (1), the middle core layer (1.1) is a PP core or a hemp core or a yarn core or a PU core, four to eight steel wire strands (1.2) are arranged on the periphery of the middle core layer (1.1), the multiple steel wire strands (1.2) are twisted to the surface of the middle core layer (1.1), the steel strand (1) is sleeved with a wear-resisting casing pipe (2), a spiral section (3) is arranged in the middle of the wear-resisting casing pipe (2), and meanwhile the tail end of the wear-resisting casing pipe (2) is provided with a casing head (4). The center of the electro-tricycle brake cable is the steel strand, and the steel strand is formed by twisting the steel wire strands, thereby being higher in strength compared with an original single-strand steel wire and not prone to breakage. Meanwhile, the wear-resisting casing pipe is arranged outside the steel strand, so that the corrosion resistance of the steel strand is improved. In addition, the spiral section is arranged in the middle of the wear-resisting casing pipe to prevent the wear-resisting casing pipe from being broken when pulled, and therefore brake strength is improved.
Description
technical field [0001] The invention relates to a brake line for an electric tricycle, which belongs to the technical field of mechanical accessories. Background technique [0002] The brake system of an electric tricycle includes brake handles, brake lines, brake calipers and other accessories. Conventional electric tricycle brake wires have poor corrosion resistance and low strength, and are easy to break after long-term use, resulting in reduced safety of electric tricycles. Contents of the invention [0003] In order to overcome the above disadvantages, the present invention provides an electric tricycle brake line that is not easy to break and has high safety. [0004] The purpose of the present invention is achieved like this: [0005] A kind of electric tricycle brake wire, it comprises the most central steel strand, and the middle of steel strand is middle core layer, and this middle core layer is PP core, hemp core, yarn core or PU core, and the periphery of des...
