A method for operating a hydrodynamic coupling device of the open 3 - line - type

摘要

A method for operating a hydrodynamic coupling device of the open 3 - line - type, the hydrodynamic coupling device comprising a which is filled with fluid or collapsible housing assembly (12), a with the housing arrangement (12) about an axis of rotation (a) rotatable impeller (20), a in the housing assembly (12) and arranged with a driven element (32) for rotation about the axis of rotation (a) which is coupled to the turbine wheel (26), a lock-up clutch (48) for the optional manufacture of a torque-transmitting connection between the housing assembly (12) and the driven element (32), wherein the lock-up clutch (48) a an inner space (24) of the housing assembly (12) into a the turbine wheel (26) containing the first space region (52) and a second spatial region (54) which divides the clutch piston (50), whereby at least when the lock-up clutch (48) of the first spatial region (52) and the second spatial region (54) in fluid exchange connection with one another, a to the first space region (52), leading to the first fluid channel region (60) and a to the first space region (52), leading to the second fluid channel region (64), wherein the first spatial region (52) via the first fluid channel region (60) or / and the second fluid channel region (64) fluid is supplied, and from the first space region (52) via the first fluid channel region (60) or / and the second fluid channel region (64) fluid can be derived, a third fluid channel region (68) at least for the supply of fluid to the second spatial region (54), in which a method for the engagement of the bridging clutch in the first space region (52) a the clutch piston (50) in the direction of engagement of the screwthreads of the fluid pressure is provided and for the disengagement of the lock-up clutch (48) in the second spatial region (54) a the clutch piston (50) in the direction of disengaging the screwthreads of the fluid pressure is provided, is characterized in that in the engaged state of the bridging clutch (48) or / and in the release state of the lock-up clutch (48) or / and for the engagement of the lock-up clutch (48) or / and for the disengagement of the lock-up clutch (48) a fluid supply pressure for the first space region (52) or / and a fluid supply pressure for the second spatial region (54) as a function of at least one operating variable is set.
