Hybrid drive

摘要

The invention relates to a fluid friction clutch (1) having a housing (2, 3), having a clutch disk (4) which is rotatable relative to the housing (2, 3), and which is rotatably arranged on an end (5) of a shaft (6) which is mounted centrally within the housing (2, 3); having a working chamber (9) between the housing (2, 3) and the clutch disk (4); having a storage chamber (10) for clutch fluid; having a supply duct (11) which leads from the storage chamber (10) to the working chamber (9); having a stationary clutch part (13) relative to which the housing (2, 3) is rotatable; and having a pump element (14), wherein the pump element (14) defines a shear gap (12) with an annular wall (19) arranged in the storage chamber (10), wherein an active element (7) is fastened to the housing (2, 3), and wherein the shear rate in the shear gap (12) can be regulated by means of an electric motor (20) which is mounted on the shaft (6).

主权项

1. A hybrid drive comprising:
a housing; an active member attached to said housing; a shaft member rotatably positioned in said housing; a clutch disk positioned in said housing and connected to said shaft member and rotatable at input speed; a working chamber between said housing and said clutch disk; a storage chamber for clutch fluid, said storage chamber comprising a plurality of first wall members; an electric motor with a stator member and a rotatable rotor member; a pump element positioned in said storage chamber and having a supply duct leading to said working chamber; a second wall member separate from said plurality of first wall members and positioned in said storage chamber, said second wall member connected to said clutch disk and rotatable therewith; said pump element connected to said rotatable rotor member and rotatable therewith; and a shear gap in said storage chamber positioned between said second wall member; wherein the shear rate of clutch fluid in the shear gap is regulated by said electric motor.
