Title:

ELECTRIC BRAKE DEVICE

Document Type and Number:

WIPO Patent Application WO/2013/008773

Kind Code:

A1

Abstract:

Provided is an electric brake device configured so that a sensor for detecting the pressing force of a friction pad is less vulnerable to the frictional heat between the friction pad and the brake disc and can detect the pressing force of the friction pad with consistent accuracy. An electric brake device (1) has a rectilinear motion mechanism for converting the rotation of a rotating shaft (10) into the rectilinear motion of an outer ring member (12) and is configured so that the outer ring member (12) presses a friction pad (8) against the brake disc (2). The electric brake device (1) also has a reaction receiving member (14) for receiving a reaction force acting axially rearward when the friction pad (8) is pressed axially forward by the outer ring member (12). An affixed member (35) is provided axially behind the reaction receiving member (14), a row (37) of magnetic poles is provided to the reaction receiving member (14), and a magnetic sensor (38) is provided to the affixed member (35).
