Structural Design and Braking Performance Verification of Electro-mechanical Brakes for Commercial Vehicles
A structural scheme of electro-mechanical brake(EMB)for commercial vehicles was pro-posed.The structural design and parameter matching were carried out,and a three-dimensional EMB model was established.In order to verify the braking performance of EMB,the electro-mechanical cou-pling dynamics model was established,and the control strategy of the braking clamping force was devel-oped.In addition,the dynamic response characteristics of EMB were simulated and analyzed with the input of step,ramp,and sine signals.The experimental results show that in typical working conditions,the variation trend of various parameters in the response process of EMB meets the expectation.
