The invention relates to a brake actuator unit, a strain sensor and an electromechanical brake. A brake actuator unit (12) for an electromechanical brake (10), the brake actuator unit having: a main shaft (44); the brake (10) includes a main shaft (44), a main shaft bearing (96) receiving the main shaft (44), and a cup-shaped brake piston bearing section (74) having a circumferential wall (76) and a base (78) on which the main shaft bearing (96) is axially supported during actuation of the brake (10). The brake actuator unit (12) also has a strain sensor (142) having a sensor element which is arranged on an outer periphery (148) of an axial section (144) of the circumferential wall (76) and is configured to detect a strain of the axial section (144) in the circumferential direction (U). Furthermore, a strain sensor (142) and an electromechanical brake (10) are provided.
本发明涉及制动致动器单元、应变传感器和机电制动器。一种用于机电制动器(10)的制动致动器单元(12),该制动致动器单元具有:主轴(44);接纳主轴(44)的主轴轴承(96),以及杯形制动活塞支承区段(74),其具有周向壁(76)和基部(78),在致动制动器(10)期间,主轴轴承(96)被轴向地支撑在基部上。制动致动器单元(12)还具有应变传感器(142),其具有传感器元件,该传感器元件布置在周向壁(76)的轴向区段(144)的外周边(148)上并且构造成检测轴向区段(144)在周向方向(U)上的应变。此外,提供了应变传感器(142)以及机电制动器(10)。
