Hybrid Drive System for a Motor Vehicle

A hybrid drive system (10) for a motor vehicle, comprising:

• an input shaft (14) which is rotatably mounted around an axis of rotation (12) and via which torques provided by an internal combustion engine introducible into the hybrid drive system (10);
• a drive shaft (18) disposed coaxially with the input shaft (14);
• an electric engine (20) which has a stator (22) and a rotor (23);
• a torque converter (24) which has an impeller (26), a converter cover (28) connected to the impeller (26) in a manner fixed against rotation, and a converter hub (30) which is connected to the converter cover (28) in a manner fixed against rotation, wherein the converter hub is connected to the rotor (23) in a manner fixed against rotation;
• a separable clutch (34) having a disc pack (36), a clutch chamber (38) in which the disc pack (36) is received, an operating piston (40), and an associated operating chamber (41), wherein via the separable clutch (34) the converter hub (30) is connectable to the input shaft (14) in a manner fixed against rotation;
• a feeding conduit (46) which is flowable through by oil and via which at least a part of the oil flowing through the feeding conduit (46) is introducible into the operating chamber (41) as operating oil to operate the operating piston (40);
• a cooling conduit (42) via which the separable clutch (34) and the electric engine (20) are providable with a cooling oil;
• and
• a first control slide (52) via which a flow volume of the cooling oil is adjustable, wherein to displace the first control slide (52), and thus to adjust the flow volume, at least a part of the oil flowing through the feeding conduit (46) is applyable to a first hydraulic active surface (54) of the first control slide (52) via the feeding conduit (46).
