WHEEL BRAKING CONTROL APPARATUS FOR REDUCING PRESSURE FLUCTUATIONS BETWEEN TWO BRAKE LINES

摘要

An anti-lock brake system is arranged such that the recirculation line from the overflow reservoir feeds into one of the brake lines downstream of the lines dividing point. A constriction, which may take the form of a simple nozzle is positioned between the recirculation line junction and the brake line dividing point for reducing the coupling of pressure fluctuations between the brake lines when the anti-lock system is actuated. With this arrangement, even upon the occurrence of sharp pressure fluctuations in one of the brake lines due to actuation of the anti-lock function, the pressure of the other brake line is not affected thereby allowing proper controlled braking in each wheel.
