Embodiment Construction

[0115] will describe together Figure 1 to Figure 6 A clutch assembly 2 of the invention for a drive train of a motor vehicle is shown. The clutch pack 2 comprises a friction plate clutch 3, and an operating device 4 for controlling the torque transmitted by the friction plate clutch. The friction plate clutch 3 is cooled and lubricated and can therefore also be referred to as a wet clutch. The clutch 3 is actuated by means 4 which can also be referred to as actuating means.

[0116] The friction plate clutch 3 comprises an inner plate carrier 5 to which an inner plate 7 is connected in a rotationally fixed and axially movable manner, and an outer plate carrier 5 to which an outer plate 8 is connected in an axially movable and rotationally fixed manner. Board carrier7. The outer plates 8 and the inner plates 6 are arranged so as to alternate in the axial direction and jointly form a plate pack 9 . The plate pack 9 is axially supported against the support plate 10 in a firs...

Abstract

The invention relates to a clutch assembly of a drive train of a motor vehicle, comprising a friction plate clutch (3), having an inner plate carrier (5) to which an inner plate (6) is connected in a rotationally fixed and axially displaceable manner, and having The outer plate (8) is connected to the outer plate carrier (7) in a rotationally fixed and axially movable manner, and the inner plate and the outer plate together form a plate group (9), and the inner plate carrier is included in the connection with the plate group At least one opening (15) in the axial overlap zone through which oil can flow to the plate pack against its axially supported support plate (10) for axially loading the plate pack Axially displaceable pressure plate (11) for operating means (4) for operating the friction plate clutch by axially displacing the pressure plate for controlling oil control through at least one opening (15) in the inner plate carrier A flow controller (16) for volumetric flow rate, the flow controller comprising a setting member (17) operable by an operating device of a friction plate clutch, the setting member comprising a cover portion (22) for covering the mouth area of ​​at least one aperture.

Description

technical field [0001] The present invention relates to a clutch assembly having a friction plate clutch and a passive lubricant supply, more particularly for use in the driveline of a motor vehicle. Friction plate clutches are used in drive trains to allow friction-based transmission of torque between two drive members, such as driveshafts and / or driving gears. They allow the drive train to shift at any speed differential under torque load. Wet friction plate clutches include multiple friction plates that are cooled and lubricated by surrounding oil. Background technique [0002] In general, an adequate supply of oil is essential for friction plate clutches to adequately lubricate the components that rotate with respect to each other, and to dissipate the heat generated by friction. On the other hand, high oil volume flow leads to drag moments and thus undesired losses. [0003] From US8388486B2 a drive train of a motor vehicle with a disengageable propeller shaft is kno...
