Title:
MOTOR VEHICLE WHEEL ANTISKID AND ANTILOCK DEVICE USING THE BRAKING CIRCUIT
Document Type and Number:
WIPO Patent Application WO2004020264
Kind Code:
A8
Abstract:
The invention 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). The device comprises a function selector (50) capable of adopting antiskid mode (50A) or antilock mode positions wherein they connect a branch line (52) to a fluid supply (54) or to a draining unit (56), and, for the or each brake cylinder, 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 means(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 said wheel.The invention further concerns a control valve.
