Abstract: To meet the high performance requirements of new energy vehicles and high-level autonomous driving for braking systems, this paper proposes a lattice-type electro-mechanical brake (EMB) actuator. The actuator employs an array of 10 independently motor-driven braking units, allowing flexible combination of working modes according to braking force demands. Based on the reference vehicle parameters, the key components are selected. Through CATIA modeling and ANSYS static analysis, it is verified that the stress and deformation of each component are within allowable limits, and the braking torque meets the requirements. The results show that the proposed mechanism offers the advantages of high structural redundancy, precise control, and fast response, providing a feasible solution for a new generation of intelligent braking technology.
