摘要： The invention concerns an economical hydraulic vehicle braking system with an anti-lock arrangement, by means of which system wheel-braking pressures in front wheel brakes and rear wheel brakes connected to a diagonal braking circuit of a four-wheeled vehicle can be varied individually in order to prevent or eliminate the risk of the wheels' locking. The anti-lock arrangement comprises one return pump per braking circuit. According to the invention, the anti-lock braking arrangement (15) is equipped with a total of four electrically controllable valves. In each of the braking circuits (I, II) there is a first valve (28, 29) between the brake master cylinder (2) and a front wheel brake (7, 8) and a second valve (30, 31) between the brake master cylinder (2) and the rear wheel brake (11, 12). All the valves take the form of normally open valves which can be closed electrically. The input (49) of each return pump (32, 33) is connected directly to the front wheel brakes (7, 8) and indirectly, by means of throttle devices (35, 36), to the rear wheel brakes (11, 12). Non-return valves (37, 38), which can be opened in the direction of the inputs (49), can be provided in series with the throttle devices (35, 36). The anti-lock braking arrangement (15) is of economical construction and enables rear wheel brake pressures to be higher than front wheel brake pressures when the system is operating in anti-lock braking mode, in order to improve the braking effect, e.g. when travelling on icy roads.
摘要翻译：本发明涉及一种具有防抱死装置的经济的液压车辆制动系统，通过该系统系统可以在连接到四轮车辆的对角制动回路的前轮制动器和后轮制动器中分别改变车轮制动压力为了防止或消除车轮锁定的风险。防抱死装置每个制动回路包括一个回油泵。根据本发明，防抱死制动装置（15）配备有总共四个电控阀。在每个制动回路（I，II）中，在制动主缸（2）和前轮制动器（7,8）之间存在第一阀（28,29），并且在第一阀制动主缸（2）和后轮制动器（11,12）。所有的阀门都采用可以电关闭的常开阀门。每个回油泵（32,33）的输入端（49）直接与前轮制动器（7,8）连接，并通过节流装置（35,36）间接与后轮制动器（11,12））。可以在输入（49）的方向上打开的止回阀（37,38）可以与节流装置（35,36）串联设置。防抱死制动装置（15）具有经济的结构，并且当系统在防抱死制动模式下运行时，使后轮制动压力高于前轮制动压力，以便改善制动效果，例如，当在冰冷的道路上旅行时。
