The invention discloses an automobile electronic mechanical drum brake. The drum brake comprises a brake bottom plate, wherein a through hole is formed in the top of one side of the brake bottom plate, limiting support plier bodies are arranged at the top and the bottom of the through hole, and one ends of the two limiting support plier bodies are fixedly connected with the brake bottom plate; andthe through hole is internally provided with a lead screw nut, and the lead screw nut is slidably connected with the brake bottom plate. According to the automobile electronic mechanical drum brake,power output by a motor is transmitted through a warm gear transmission mechanism, an electromagnetic clutch and a ball screw pair, the lead screw nut pushes a connecting rod force-increasing mechanism, brake shoes are tensioned inwards, friction linings press the brake drum to generate braking force, so that braking is realized. The automobile electronic mechanical drum brake is small in structural size, high in space utilization rate, convenient to install and maintain, good in braking performance, short in brake clearance eliminating time, accurate in braking force estimation model, free ofreverse rotation of the motor during braking relieving, high in response speed and simultaneously provided with a driving braking function and a parking braking function.
Description
technical field [0001] The invention relates to the technical field of brakes, and more specifically, the invention relates to an automotive electromechanical drum brake. Background technique [0002] With the rapid development of automobile intelligence, automobile wire control technology has emerged at the historic moment, and has been widely used in the whole vehicle. This technology is a new control system based on information interaction system and real-time control. As a branch of automotive wire control technology, the EMB system is used to replace traditional hydraulic and pneumatic braking systems. Its structural principle and control algorithm are very different from traditional braking systems. It is a brand new automotive braking system. idea. [0003] The utility model patent with the patent application number 201320839113.1 discloses a toggle-type electromechanical brake, which consists of a brake disc, a caliper, a bracket, a first pin assembly, a connector, ...
