Electro-mechanical shifting actuator for robotized gear box, has electric motor whose usage mode is cyclic with sliding gear approach phase during which setpoint acceleration is periodically rectangular between two maximum values

摘要

The actuator has a movement reducer, a movement transformation link, and an electric motor whose usage mode is cyclic with approach phase of a sliding gear, synchronization phase and gear ratio or jaw clutching engagement phase. The motor-reducer-link system presents a stiffness which along with reduction ratio defines mechanical dimensions of the actuator. The engagement, approach and synchronization phases define electrical dimensions of the actuator, where during the approach phase setpoint acceleration is periodically rectangular between two maximum values. An independent claim is also included for a method of controlling an electro-mechanical shifting actuator for a robotized gear box.
