Description

technical field [0001] The patent of the present invention relates to a novel electromechanical brake actuator with an all-mechanical structure, simple structure, compact structure and low cost, and belongs to the technical field of mechanical brake systems. Background technique [0002] The traditional hydraulic braking system has a history of nearly a hundred years, including the brake master cylinder and master cylinder piston, brake oil pipe, brake wheel cylinder and piston, brake block (shoe) and brake disc (hub), etc. The main components. Due to the existence of hydraulic pipelines, its main disadvantages are: complex design and manufacture, slow system response, difficult maintenance, easy leakage, and environmental pollution. With the development of the automobile industry, people pay more and more attention to the active safety performance of automobiles and the environmental protection of automobiles. It is difficult for traditional hydraulic brake systems to meet...
