    • A hydraulic vehicle brake system in which normal service brake operation can be carried out by using external hydraulic energy, and in the event of a lack of external hydraulic energy, auxiliary brake operation by muscle power is possible, with a hydraulic transmission that comes from a master cylinder that can be actuated by means of the brake pedal. The external hydraulic energy is stored, for example, in an accumulator with a gas buffer, which can lead to a gas content in the hydraulic fluid for the service brake operation. The system includes a dual-circuit master cylinder associated with those wheel brakes of a vehicle axle that make a higher contribution to the vehicle deceleration and at the same time, cylinder/piston devices are installed between these wheel brakes and their associated service brake valves for the purpose of preventing hydraulic fluid from getting into these wheel brakes from the external energy source. The advantage is that neither gas nor air is carried into the wheel brakes where it could lead to the formation of bubbles in the event of a pressure drop and would be disadvantageous for an auxiliary brake operation by the master cylinder. The cylinder/piston devices increase the operational safety of the vehicle brake system when braking by muscle power.
    • 一种液压车辆制动系统,其中可以通过使用外部液压能来执行正常的行车制动操作,并且在缺乏外部液压能量的情况下,通过肌肉力量进行辅助制动操作是可能的,其中液压传动装置来自 主缸,可通过制动踏板启动。 外部液压能量例如储存在具有气体缓冲器的蓄液器中,这可以导致用于制动操作的液压流体中的气体含量。 该系统包括与车轴的那些车轮制动器相关联的双回路主缸,其对车辆减速度做出较高的贡献,并且同时,缸/活塞装置安装在这些车轮制动器及其相关联的行驶制动阀之间, 防止液压流体从外部能源进入这些轮子制动器的目的。 优点是气体和空气都不会被携带到车轮制动器中,从而在压力下降的情况下可能导致气泡的形成,并且不利于主缸的辅助制动操作。 气缸/活塞装置通过肌肉力量制动时增加了车辆制动系统的操作安全性。
