Abstract
A brake system with an electric actuator comprises a driving device and a brake assembly. A coupling is arranged on an output shaft of the driving device in a sleeving manner and synchronously rotates with the output shaft. Input teeth are arranged on the output shaft in a sleeving manner. A brake torsional spring is mounted in a brake friction sleeve, and both the coupling and a brake pad are arranged in the brake torsional spring in a sleeving manner. When the coupling drives the brake pad to rotate, the brake pad drives the brake torsional spring to synchronously rotate relative to the brake friction sleeve. The output end of a transmission mechanism is connected with the input teeth.
