Cooling-oil guiding element, and drive train and hybrid module having said cooling-oil guiding element

A cooling oil guiding device for a clutch arrangement, comprising:

• a piston that is axially moveable;
• a clutch that can be actuated via the piston to change between an actuated position and an open position, wherein the piston is arranged radially inwardly of the clutch;
• a sealing element
• a compensation space cover that is stationary in axial direction;
• a seal cover which is coupled to the piston, wherein the compensation space cover and the seal cover overlap radially outwardly in axial direction and are connected to be movable relative to one another in axial direction via the sealing element;
• a compensation space delimited by the compensation space cover and the seal cover;
• a pressure space that is separated from the compensation space by the piston;
• an oil channel is provided in the seal cover that opens outward in radial direction and arranged between the seal cover and the piston;
• an overflow opening that connects the compensation space to the oil channel;
• and a control edge provided at a component part that is axially immovable relative to the piston by at least part of an oil flow exiting from the oil channel is guided through the clutch when the clutch is closed and is guided past the clutch when the clutch is open,
• wherein the control edge is formed as a radially inwardly protruding projection which, at least on one side in axial direction, delimits an annular space with radial through-openings distributed along a circumference.

A powertrain, comprising:

• a clutch arrangement comprising:
• a cooling oil guiding device for the clutch arrangement, comprising:
• a piston that is axially moveable;
• a clutch that can be actuated via the piston to change between an actuated position and an open position, wherein the piston is arranged radially inwardly of the clutch;
• a sealing element
• a compensation space cover that is stationary in axial direction;
• a seal cover which is coupled to the piston, wherein the compensation space cover and the seal cover overlap radially outwardly in axial direction and are connected to be movable relative to one another in axial direction via the sealing element;
• a compensation space delimited by the compensation space cover and the seal cover;
• a pressure space that is separated from the compensation space by the piston;
• an oil channel is provided in the seal cover that opens outward in radial direction and arranged between the seal cover and the piston;
• an overflow opening that connects the compensation space to the oil channel;
• and
• a control edge configured as a radially inner projection that extends inward from the compensation space cover that is axially immovable relative to the piston by at least part of an oil flow exiting from the oil channel is guided through the clutch with force when the clutch is closed and is guided past the clutch when the clutch is open.

A hybrid module for a powertrain, comprising:

• a rotor of an electric machine of the hybrid module;
• and
• a cooling oil guiding device for a clutch arrangement, comprising:
• a piston that is axially moveable;

• a sealing element
• a compensation space cover that is stationary in axial direction;
• a seal cover which is coupled to the piston, wherein the compensation space cover and the seal cover overlap radially outwardly in axial direction and are connected to be movable relative to one another in axial direction via the sealing element;
• a compensation space delimited by the compensation space cover and the seal cover;
• a pressure space that is separated from the compensation space by the piston;
• an oil channel is provided in the seal cover that opens outward in radial direction and arranged between the seal cover and the piston;
• an overflow opening that connects the compensation space to the oil channel;
• and
• a control edge configured as a radially inner projection that extends inward from the compensation space cover that is axially immovable relative to the piston by at least part of an oil flow exiting from the oil channel is guided through the clutch with force when the clutch is closed and is guided past the clutch when the clutch is open.
