CONTROL DEVICE FOR LOCKUP CLUTCH INCORPORATED IN TORQUE CONVERTER

摘要: PURPOSE:To prevent damage due to slippage at the time of high-speed running by supplying oil pressure corresponding a car velocity lockup clutch incorporated in torque converter when it reaches designated velocity. CONSTITUTION:A spool 40 regulating valve S1 control device S is moved an equilibrium position with spring 42 difference between line PL from hydraulic Q and governor PG introduced into chamber 41. Line such displacement partially returned reservoir 30 through orifice 43 passage 44. On other hand, preset velocity, 45 on-off S2 left among drop, 46 supply 2a 2. Thus, connected, mechanical efficiency fuel cost can be improved, shock low-speed softened temporary slippage, prevented.
