antriebsschlupf and antiblockiervorrichtung for wheels of a vehicle equipped with a brake system

摘要

The device comprises a function selector (50) capable of adopting anti-skid mode (50A) or antilock mode positions where they connect a branch line (52) to a fluid supply (54) or to a draining unit (56), and, for the or each brake cylinder. There is a control valve (110, 210, 310, 410) capable of adopting a normal braking position (110A, 210A, 310A, 410A) to connect the cylinder to the braking line (44, 46) and at least one specific mode position (110B, 210B, 310B, 410B) to connect the cylinder to the branch line (52) which the function selector connects to the draining or the supply unit. The device comprises units (120, 220, 320, 420, UC) for detecting a situation involving skid or a wheel locking trend and for accordingly control the function selector (50) and the control valve associated with the brake cylinder associated with the wheel. The device concerns a braking system comprising one or several brake cylinders (100, 200, 300, 400) each associated with at least one wheel, a fluid source (10) and a brake control (14) for controlling fluid supply of the cylinder(s) by at least one braking valve and a brake line (44, 46).
