DEVICE OF HYDRAULIC CIRCUIT IN WET DCT USING ASSISTANT MOTOR-DRIVEN PUMP

摘要

The present invention relates to a wet DCT hydraulic circuit device using an auxiliary motor-driven pump. More specifically, the wet DCT hydraulic circuit device using an auxiliary motor-driven pump reduces a control flow rate required by a system. The present invention comprises: a constantly operated mechanical pump connected to a power shaft of an engine; an auxiliary motor-driven pump; a regulator valve which is a spool valve for controlling line pressure; a pressure control solenoid valve (PPV) for controlling system pressure; the PPV for controlling a valve clutch; a SVFS which is a linear Sol valve for controlling pressure; an accumulation for a decompression valve; a residual pressure valve; an accumulation; a lubrication reducing valve (LRV1); a secondary regulating valve (LRV2); K1 and K2 wet multi-plate clutches; and a check ball to prevent introduction of air.
