Title: Clutch system
Inventor: KIM DONG U
IPC: F16H63/00
Filed: 1999-07-20
Abstract: PURPOSE: A clutch system is provided to broaden life time span of a clutch and to secure stability in driving by preventing impact caused difference in filling time of cylinders in different kinds of clutches. CONSTITUTION: A change valve(5) is on a first position and oil starts to be supplied to a first clutch through a modulation valve(3). The oil is filled in the cylinder of the first clutch and the cylinder starts to pressurize a disk plate. Then, the oil is collected in an accumulator(15). Clutch pressure increases continuously and keeps its level regular. When the change valve moves to a second position, the oil flows into a second clutch through a channel(31). The oil flows into two channels(35,36). A part of the oil flowing into the channel(35) flows into the cylinder of the second clutch while the other channel(36) oil flows into a flow control valve(19). Both accumulators(15,17) between the clutches(11,13) and change valve function to adjust the discharge speed of oil from each clutch. Therefore, a user removes or reduces difference in time required for filling the first/second clutches through the accumulators.
