The invention relates to a brake cable for an electric tricycle that can be fixed and has adjustable gears, and is characterized in that it includes the most central steel strand (1), and the middle of the steel strand (1) is an intermediate core layer (1.1), The middle core layer (1) is a PP core, hemp core, yarn core or PU core, four to eight steel wire strands (1.2) are arranged on the periphery of the middle core layer (1.1), and multiple steel wire strands (1.2) are stranded On the surface of the middle core layer (1.1), a wear-resistant sleeve (2) is sheathed on the outside of the steel strand (1), and a helical segment (3) is set in the middle of the wear-resistant sleeve (2), and the helical segment (3) ), and the end of the wear-resistant sleeve (2) is provided with a sleeve (4). The center of this fixed and gear-adjustable electric tricycle brake wire is a steel strand. After the steel strand is twisted by steel wire strands, it has higher strength than the original single-strand steel wire and is not easy to break; at the same time, the steel strand A wear-resistant sleeve is arranged on the outside, thereby improving the corrosion resistance of the steel strand, and a helical section is arranged in the middle of the wear-resistant sleeve to prevent it from breaking, thereby improving the strength of the brake.
Description
technical field [0001] The invention relates to a brake cable for an electric tricycle that can be fixed and has an adjustable gear position, and 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 lines that can be fixed and have adjustable gears have poor corrosion resistance and low strength, and are easy to break after long-term use, resulting in reduced safety of electric tricycles; High; and the ordinary throttle cable gear is not adjustable. Contents of the invention [0003] In order to overcome the above disadvantages, the present invention provides a brake line for an electric tricycle that is not easy to break, has high safety, can be fixed, and has adjustable gears. [0004] The purpose of the present invention is achieved like this: [0005] A fixed and gear-adjustable el...
