Problems solved by technology

However, this coupling device overpressure has many disadvantages
On the one hand, the actuating mechanism of the coupling device consumes more energy and also generates noise, which the driver of the motor vehicle perceives as an acoustic load
In addition, the actuating mechanism is subjected to unnecessarily high loads, which adversely affects its lifespan
Finally, the determination of the actual transmitted torque has a low precision, since the range of values ​​in which this actually transmitted torque is enlarged

Embodiment Construction

[0032] The drawing shows a schematic diagram of a drive train 1 , which is, for example, a component of a motor vehicle, not specifically shown. For example, drive train 1 has a primary transaxle 2 and a secondary transaxle 3 . The primary transaxle 2 has, for example, half shafts 4 and 5 , which are operatively connected to one another via an axle differential 6 . Wheels 7 are provided on each half axle 4 and 5 . Similarly, secondary drive axle 3 has half shafts 8 and 9 , which are operatively connected to one another via an axle differential 10 . Wheels 7 are likewise arranged on each axle shaft 8 and 9 .

[0033] The primary transaxle 2 and the secondary transaxle 3 are operatively connected to one another via a coupling device 11 with adjustable transmission torque. For example, the axle shafts 4 and 5 and 8 and 9 are here respectively present as output shafts of the corresponding axle differentials 6 and 10 , while the input shafts 12 and 13 of the axle differentials 6...

Abstract

The invention relates to a method for operating a drive train (1) for a motor vehicle, comprising at least one primary drive axle (2) and at least one secondary drive axle (3) which are operatively interconnected to an adjustable transmission torque by means of a clutch (11). According to the invention, the transmission torque is reduced when wheel slip exceeding a determined slip threshold value is detected on the secondary drive axle (3). The invention also relates to a drive train (1) for a motor vehicle.

Description

technical field [0001] The invention relates to a method for operating a drive train of a motor vehicle having at least one primary drive axle and at least one secondary drive axle, which can be controlled by transmitting torque The tuned coupling devices are operatively connected to each other. The invention also relates to a drive train for a motor vehicle. Background technique [0002] The method is used for operating a drive train, wherein the operation is for example aimed at driving, in particular accelerating, a motor vehicle. A drive train is provided for use in a motor vehicle, so that the invention also relates to a motor vehicle with a correspondingly designed drive train. The drive train has at least one primary drive axle and at least one secondary drive axle. The primary drive axle and the secondary drive axle are operatively connected to each other via a coupling device, wherein the transmission torque of the coupling device, ie the torque transmitted betwe...
