Description

Technical Field

[0001] The utility model relates to the technical field of cables, in particular to a high-strength ABS cable for electric vehicles. Background Art

[0002] The anti-lock braking system, referred to as ABS, is used to automatically control the braking force of the brakes when the car brakes to prevent the car from braking all at once. It uses intermittent braking to determine the slip rate of the wheel in real time and keep the slip rate of the wheel near the optimal value when braking. The cables used in the wheel wiring harness ABS system will bend and twist as the wheel turns. Even in the static process, the cables are in a "U-shaped" bending state, so the cables in the ABS system are always in a bent state.

[0003] Existing cables have no protective structure when being stretched or bent, so the cables are easily broken after long-term use, which affects the service life of the cables. Utility Model Content
