Abstract
本发明涉及一种防抱死制动单元，包括作用于关联阀单元(30)的活塞(40)上的单个致动螺线管(31)。该螺线管使活塞在与制动钳流体连通的初级室(38)内移动。活塞的移动关闭阀单元内所形成的旁路通道(50)，该旁路通道在正常情况下使主缸与制动钳相连接。通过关闭旁路通道(50)，作用于制动钳上的压力停止累增。同时，活塞(40)的相同致动运动开放阀单元内的流出通道，允许制动液从初级室(38)排放到膨胀室中。该膨胀室为阀单元(30)与制动钳之间所含的制动液给予扩大体积，从而降低了制动液作用于制动钳的压力。

The invention relates to an anti-lock brake unit comprising a single actuation solenoid (31) acting on a piston (40) of an associated valve unit (30). The solenoid moves a piston within a primary chamber (38) in fluid communication with the brake caliper. The movement of the piston closes a bypass passage (50) formed in the valve unit, which normally connects the master cylinder with the brake caliper. By closing the bypass channel (50), the pressure acting on the brake caliper ceases to build up. At the same time, the same actuation movement of the piston (40) opens an outflow channel in the valve unit, allowing brake fluid to drain from the primary chamber (38) into the expansion chamber. The expansion chamber gives an enlarged volume to the brake fluid contained between the valve unit (30) and the brake caliper, thereby reducing the pressure of the brake fluid acting on the brake caliper.
