Brake mechanism for motor vehicles - has anti-wheel lock device with sensors and magnetic valves on vehicle wheels

摘要

There is a change over valve that operates depending on the threshold valve opening a bypass channel. This also makes part of the magnetic valve inoperative, until the non-locking brake pressure is reached. One brake circuit is controlled through a brake valve and a second circuit is loaded from a master cylinder. Both circuits are simultaneously operated by the driver. The circuit change over valve is in the second circuit separating the master cylinder from the wheel cylinders and connecting the brake valve controlled circuit to the wheel cylinders. The change over valve is a 3/2 way magnetic valve or a pressure operated slide valve. Each change over valve monitors one front and one rear brake cylinder.
