Title: Slip controlling device for lock-up torque converter
Inventor: MURASUGI TAKU
IPC: F16H61/14
Filed: 1985-09-25
Abstract: PURPOSE:To prevent the early wear of a clutch facing by providing a slip control changing means which switches a slip control valve to a slip position according to the temperature of the torque converter working oil, an engine load, and a car speed. CONSTITUTION:When a slip control valve 25 is at the 'converter position', the converter chamber pressure PC becomes equal to the pressure in a lock-up control chamber 18. Therefore, a lock-up clutch 16 maintains the 'release position' and operates in a converter state, without performing the slip control. When the slip control valve 25 is at the 'slip position', however, pressure PL in the lock-up control chamber 18 is determined by the opening of a variable flow-rate orifice 19. In accordance with this pressure PL, the lock-up clutch 16 slides and is engaged with a converter cover 5, thereby conducting the power transmission. Since this slip-control-area-changing-means is determined in correspondence to the working oil temperature, engine load, and car speed, both the wear of the clutch facing and a rise of the working oil temperature can be prevented.
