    • There is the problem of adjusting a clearance in electromechanically or electromotively operated brakes because automatic resetting means, which are provided for hydraulic brakes, cannot be used in brakes of the above type. Initially, it is necessary to determine a neutral position of the motor which is defined by the friction elements just abutting the brake disc in this position. This situation is determined by a detection device which exhibits the following operation in one preferred embodiment. The motor is driven from an unknown position by a constant motor torque so that the friction linings are moved towards the brake disc. The motor will speed up because the resistances remain constant in the starting stroke. An abrupt deceleration of the motor will be caused when the friction linings are applied to the brake disc. The zero passage of the angular acceleration can be sensed and interpreted as an application of the friction linings on the brake disc. Subsequently, a so-called contact signal is generated, with the result that the motor is restored in a position-controlled manner by a defined angle which corresponds to the clearance being adjusted.
    • 由于设置用于液压制动器的自动复位装置不能用于上述类型的制动器,所以存在调节机电或电动制动器中的间隙的问题。首先,需要确定电动机的中性位置 由在该位置处刚好邻接制动盘的摩擦元件限定。这种情况由在一个优选实施例中显示以下操作的检测装置确定。 电动机通过恒定的电机扭矩从未知位置驱动,使得摩擦衬片朝向制动盘移动。 由于电阻在启动行程中保持恒定,电机将加速。 当摩擦衬片施加到制动盘时,会引起电机的急剧减速。 可以感测角度加速度的零通道并将其解释为摩擦衬片在制动盘上的应用。 随后,产生所谓的接触信号,结果电动机以位置控制的方式恢复与调节间隙对应的限定角度。
