Direct coupling controller of torque converter for automatic speed change gear for car

Abstract

Abstract PURPOSE:To improve the comfortability by increasing the coupling force in accordance to the car speed upon operation of a direct couple clutch having slide characteristic thereby absorbing high torque variation of engine and providing the stillness. CONSTITUTION:Since a direct couple clutch Cl has weak coupling force, if it is subjected to high torque variation from an engine E at the start, it will produce the slippage easily under peak load. Consequently the high torque variation is not transmitted to the system downstream from the torque converter T, to assure quite smooth operation of said clutch Cl. As a result, the output oil pressure level for determining the start of said clutch Cl or the car speed v0 can be selected in the quite low region.
