Antilocking braking system for double axle vehicle - has circuit evaluating RPM and determining rotation retardation of wheels and pressure control

摘要

The braking system has a conventional ABS control circuit (40). Each front (12,12') and rear (10,10') wheel is provided with a r.p.m. sensor (26,26';28,28'). Upon braking, the pressure control supplies medium to the brakes of the rear wheels (10,10'). A brake pressure remains so long as it is greater than the pressure pertaining at the brakes of the front wheels (12,12') and as long as the rotation retardation of the rear wheels remains under a specified value. At the start of braking, the pressure control supplies medium at a pressure to the brakes of the front wheels which corresponds only to the feed pressure of the brakes of the front wheels so long as the rotation retardation of the rear wheels remains under a specified value. ADVANTAGE - Developed and arranged to ensure that brake lines have uniform wear to give as long as possible working life.
