Abstract
An electromechanical brake is configured to detect a change in motor characteristics through a parking mechanism added to an existing electromechanical brake. Particularly, the electromechanical brake controls braking force by predicting a change in motor characteristics even in the event of a breakdown of a force sensor or even in a case in which no force sensor is utilized.
Claims18
An electromechanical brake configured to detect a change in motor characteristics, the electromechanical brake comprising:
- a motor unit which rotates a driving shaft;
- a braking unit which produces braking force or cuts off the braking force in accordance with the rotation of the driving shaft;
- a parking drive unit which operates a driving rod;
- a parking ring which is freely and rotatably installed on the driving shaft and has catching portions formed radially;
- a rotatable member which is installed on the driving shaft so as to be rotatable alone or together with the parking ring in accordance with the rotation of the driving shaft;
- and
- an elastic body which is elastically deformed in accordance with a relative displacement difference between the rotatable member and the parking ring.
