Hydraulic system for motor vehicle's clutch

摘要

The system has a pump (16) conveying a hydraulic fluid stream (i-ATF) to a hydraulic valve (20) via a heat exchanger (18). The valve divides the stream into a set of partial streams (i-ATF1, i-ATF2). The streams flow to a reservoir (22) via friction linings and via a hydraulic path (24), respectively. The system upgrades or reduces cooling of a clutch (12) by increasing the partial streams, respectively. The system temporarily upgrades cooling of the clutch, in an event of changeover of torque transferring through a partial gearbox (TG1) to torque transferring through a partial gearbox (TG2).
