Actuator for an electromechanical brake, a brake including such an actuator, a vehicle including at least one such brake, and a method of implementing said actuator

摘要

The invention relates to an actuator for an electromechanical brake, the actuator comprising a pusher and a first drive member arranged to move the pusher in register with a stack of disks and to apply a braking pressure to the stack of disks, the actuator including a second drive member comprising a piezoelectric assembly suitable for modulating the braking pressure applied to the stack of disks. According to the invention, the piezoelectric assembly is disposed inside the actuator so as to present an end that is stationary.
