Title
(EN) MULTIPLEXED HYDRAULIC CONTROL FOR A TWO-COUPLING ALL-WHEEL DRIVE SYSTEM
(FR) COMMANDE HYDRAULIQUE MULTIPLEXEE DE LA TRANSMISSION A DEUX ACCOUPLEMENTS D'UN 4 X 4
Abstract
(EN)
The present invention is directed toward incorporating a single actuation unit to actuate two or more couplings. The clutch actuation arrangement has a first coupling (36) connected to a first valve (32), a second coupling (38) connected to a second valve (34), and an actuator (24) operably connected to the first valve (32) and the second valve (34). The first valve (32) and the second valve (34) control fluid flow to the first coupling (36) and the second coupling (38). The clutch actuation arrangement also includes an elongated cylinder (31 ) operably connected to the first valve (32) and second valve (34). A piston (30) is slidably disposed in the elongated cylinder (31), wherein the piston (30) controls the amount of pressure presented to the first and second valves (32,34). The clutch actuation arrangement also includes a ball screw (28) connected to the piston (31 ), a motor (26) operably connected to the ball screw (28), wherein the motor (26) rotates the ball screw (28) to translate the piston (30) in the elongated cylinder (31 ).
(FR)
L'invention porte sur l'utilisation d'une seule commande d'embrayage agissant sur au moins deux accouplements. Le système d'embrayage comporte: un premier accouplement (36) relié à une première soupape (32), un deuxième accouplement (38) relié à une deuxième soupape (34), et un actionneur (24) relié à la première et à la deuxième soupape. La première (32) et la deuxième (34) soupape contrôlent respectivement la distribution de fluide au premier (38) et au deuxième (38) accouplement. La commande d'embrayage comporte également un cylindre allongé (31) relié à la première (32) et la deuxième (34) soupape, dans lequel coulisse un piston (30) agissant sur la pression présentée aux soupapes (32,34). La commande d'embrayage comporte en outre: une vis à billes (28) reliée au piston (30), et un moteur (26) faisant tourner la vis à billes (28) pour déplacer le piston (30) dans le cylindre (31).
