ELECTRIC DIRECT ACTING ACTUATOR AND ELECTRIC BRAKE DEVICE |
摘要 |
<p>An electric brake system is proposed which includes an electric linear motion actuator and can generate the required braking force with high accuracy. A load sensor (30) is provided in a motion converting mechanism of the actuator which converts the rotary motion of a rotary shaft (4) to which the rotation of an electric motor (2) is transmitted to linear motion of an outer ring member (5) as an output member. The load sensor (30) detects the pushing force with which the outer ring member (5) linearly drives a driven member. With this arrangement, if the driven member is a braking member of an electric brake system, it is possible to directly detect the braking force applied by the driven member and thus to accurately generate the required braking force.</p> |
