Problems solved by technology

Such an overshoot (that is to say the transmission of a torque which sometimes (teilweise) considerably exceeds the set torque via the disc clutch) can overload and damage the disc clutch itself on the one hand but also other components of the motor vehicle , destroy when necessary

Embodiment Construction

[0052] figure 1 Shown is a motor vehicle 11 with a drive unit 13 and a disc clutch 1 which is arranged on the half shaft 10 of the motor vehicle 11 for torque transmission, so that by closing the disc clutch 1 the motor Only one wheel 12 of motor vehicle 11 can be connected in a torque-transmitting manner to drive unit 13 of motor vehicle 11 . The drive unit 13 is connected to the half shaft 10 via a transmission 27 . The half shaft 10 includes a drive shaft 2 and an output shaft 3 , which can be connected to each other in a torque-transmittable manner via a multi-plate clutch 1 .

[0053] figure 2 The arrangement of the disk clutch 1 on the half shaft 10 is shown, wherein the disk clutch 1 is hydraulically actuated. In the case of a disc clutch 1 , the (outer) disc 15 is connected in a rotationally fixed manner to the outer disc carrier and the (inner) disc 15 to the inner disc carrier. Each disc carrier is connected in a rotationally fixed manner to a member of the set ...

Abstract

The invention relates to a method for actuating a multi-plate clutch 1 between an input shaft 2 and an output shaft 3 for the switchable transmission of torques, wherein, when there is a torque requirement 4 and a subsequent engagement of the multi-plate clutch 1, at least the following steps are carried out: a) determining a target engagement force 6, effective in an axial direction 5, of the multi-plate clutch 1 for the transmission of a target torque 9 to the output shaft 3; b) determining and setting a limit engagement force 7 which is smaller than the target engagement force 6; and c) setting the target engagement force 6 in a delayed manner. The limitation of the target engagement force 6 to the limit engagement force 7 means that a transmission of an actual torque 8 is realised, wherein a maximum actual torque 8 transmitted when the multi-plate clutch 1 is engaged exceeds a target torque 9 to be transmitted by at most 5%.

Description

technical field [0001] The invention relates to a method for actuating a multi-disk clutch, in particular a multi-disk clutch, which is arranged on a half-shaft of a motor vehicle, so that only one of the motor vehicle's The wheels are connected in a torque-transmitting manner to a drive unit of the motor vehicle. Background technique [0002] Disk clutches are known in particular as ETM (Electronic Torque Manager, Electronic Torque Manager) or EMCD (Electro-Magnetic Control Device, Electromagnetic Control Device), electrically motor-type actively adjustable, for engaging or Part of the clutch of the permanent all-wheel drive, which can also be used as an active axle lock. [0003] Preferably, the plate clutch is part of a hydraulically actuatable clutch (HCA-hydraulic clutch actuator). [0004] Such disc clutches are known. In this case, the outer disc is connected in a rotationally fixed manner to the outer disc carrier and the inner disc to the inner disc carrier. Eac...
