The invention relates to a pneumatic brake pedal module. A pneumatic brake pedal module for a "brake-by-wire" brake system of a vehicle is specified, having a pivotally mounted brake pedal and having a damping unit mechanically coupled to the brake pedal in order to generate resistance when the brake pedal is actuated. The damping unit comprises a housing and a piston, which is movably mounted in the housing and divides the interior of the housing into a pressure chamber and a vacuum chamber, the pressure chamber and the vacuum chamber being fluidically connected to each other, and the piston has a circumferential annular space on the running surface thereof, in which annular space the sealing ring is accommodated in an axially movable manner. The sealing ring is located at least in the flow path between the pressure chamber and the vacuum chamber and forms a restrictor in at least one flow path, which restrictor releases different flow cross-sections in the at least one flow path according to the axial direction of movement and inhibits the movement of the piston with varying degrees of strength according to the direction of movement of the piston.

    本发明涉及气动制动踏板模块。详细说明了用于车辆的“线控制动”制动系统的气动制动踏板模块,其具有能枢转地安装的制动踏板并具有阻尼单元,阻尼单元机械联接到制动踏板以便在制动踏板被致动时产生阻力。阻尼单元包括壳体和活塞,活塞能移动地安装在壳体中并将壳体的内部空间划分为压力室和真空室,其中,压力室和真空室在流方面相互连接,并且活塞在其运行表面上具有环绕的环形空间,密封环以能轴向移动的方式容纳在环形空间中。密封环至少位于压力室和真空室之间的流动路径中并在至少一条流动路径中形成限制器,限制器根据移动的轴向方向而释放至少一条流动路径中的不同的流动横截面,并根据所述活塞的移动方向以不同程度的强度抑制活塞的移动。
