An electric brake system (100) for braking a vehicle comprises: a central drive gear (3); a first engagement member (7) configured to rotate together with the central drive gear (3) about an axis (A); and a second engagement member (11) configured to selectively engage or disengage the first engagement member (7) according to a position of the second engagement member (11). The parking brake actuator (15) is configured to move the second engagement member (11) between a service brake position (S) and a parking brake position (P). In the service brake position (S), the engagement members (7, 11) are mechanically disengaged and the central drive gear (3) is free to rotate independently of the second engagement member (11). In the parking brake position (P), the engagement members (7, 11) mechanically engage to prevent rotation of the center drive gear (3) in the brake deactivation direction.
一种用于制动车辆的电动制动系统(100)包括:中心传动齿轮(3);第一接合构件(7),其被配置成与所述中心传动齿轮(3)一起围绕轴线(A)旋转;以及第二接合构件(11),所述第二接合构件(11)被配置成根据所述第二接合构件(11)的位置选择性地接合或脱离第一接合构件(7)。停车制动致动器(15)被配置成在行车制动位置(S)与停车制动位置(P)之间移动第二接合构件(11)。在行车制动位置(S)中,接合构件(7、11)机械地脱离,并且中心传动齿轮(3)独立于第二接合构件(11)自由旋转。在停车制动位置(P)中,接合构件(7、11)机械地接合以防止中心传动齿轮(3)沿制动停用方向旋转。
