The invention relates to an electromechanical brake booster (1) for a vehicle, comprising a spindle nut (22) which interacts with an axially displaceable spindle (21), comprising an actuator (4) for rotationally driving the spindle nut (22) in order to displace the spindle (21) in an actuation direction, comprising a pressure piston (9) which can be displaced through the spindle (21) in the actuation direction, the invention relates to a brake booster (1), one end of which can be coupled to a master brake cylinder (2) and the other end of which can be operatively connected via a coupling device (14) to a main shaft (21) and to a coupling rod (6) that can be connected to a brake pedal, having at least one preloaded return spring (26), which acts counter to the actuation direction, the invention relates to a clutch device (1) for a motor vehicle, comprising a particularly multi-part housing (11) which contains at least a pressure piston (9), a coupling device (14) and a return spring (26), comprising at least one pull rod (12, 13) which is fastened to the housing (11) and which extends parallel to a main shaft (21) through the housing (11), and comprising an anti-twist device (27) for the main shaft (21). According to the invention, the anti-twist device (27) has at least one rotational stop (34) fixedly connected to the spindle (21) and at least one rotational counter-stop (35) formed by the housing (11), by means of which rotational counter-stop at least a twist of the spindle (21) in the housing (11) is limited.

    本发明涉及一种用于车辆的机电的制动力放大器(1),具有主轴螺母(22),所述主轴螺母与轴向可移动地支承的主轴(21)作用接合,具有用于转动驱动所述主轴螺母(22)以使主轴(21)在操纵方向上移动的致动器(4),具有可穿过主轴(21)在操纵方向上移动的压力活塞(9),所述制动力放大器一端可与主制动缸(2)耦合,并且另一端可通过耦合装置(14)与主轴(21)和可与制动踏板连接的耦合杆(6)作用连接,具有至少一个被预紧的回位弹簧(26),所述回位弹簧逆着操纵方向作用,具有至少包含压力活塞(9)、耦合装置(14)和回位弹簧(26)的特别是多部件的壳体(11),具有至少一个固定在壳体(11)上并且平行于主轴(21)穿过壳体(11)延伸的拉杆(12、13),并且具有用于主轴(21)的防扭装置(27)。规定,所述防扭装置(27)具有至少一个与主轴(21)固定连接的转动止挡(34)和至少一个由壳体(11)形成的转动逆止挡(35),通过所述转动逆止挡至少限制主轴(21)在壳体(11)中的扭转。
