Document Type and Number:
Japanese Patent JP2004525321
Kind Code:
A
Abstract:
A hydrostatic transmission circuit for a vehicle having at least two displacement members ( 12 ) driven by at least one hydraulic motor ( 10 ) having a feed main duct and a discharge main duct ( 16, 18 ). Skid control means for controlling skidding of at least one displacement member comprise a skid control valve ( 20 ) and an additional valve ( 22 ) that are disposed in parallel on a main duct ( 16 ). At least the skid control valve ( 20 ) has a constriction of variable section, while the additional valve has two end positions ( 22 A, 22 B), in which its through sections are respectively at their maximum and at their minimum. Control means (UC, 26, 28 ) make it possible to cause said valves to move as a function of a skid situation detected by detection means ( 24 ).
