Problems solved by technology

Even in the disconnected state, however, the torque-transmitting components of the connectable drive shaft also rotate together, which leads to undesired power losses (Verlustleistung)
This loss of power results in a multi-axle motor vehicle with a waiting drive train having a higher fuel consumption than a single-axle motor vehicle

Embodiment Construction

[0046] 1 to 12 are initially described jointly in view of their commonality. In each case a coupling assembly 2 is shown, which is used to couple or disconnect the drive shaft to the longitudinal drive shaft of the motor vehicle and to adjust the force acting on the drive shaft as required. Torque distribution. As an assembly, the coupling assembly 2 comprises a friction coupling 3 and a differential transmission 4, which are connected in series with regard to torque flow, wherein a switching coupling can also be arranged between the friction coupling 3 and the differential transmission 4 41.

[0047] The friction coupling 3 comprises a coupling input part 6 and a coupling output part 8, the coupling input part 6 being firmly connected with a crown gear (Tellerrad) 7 for introducing torque into the coupling assembly 2, the coupling The output part 8 serves to drive the differential gear 4 . Furthermore, the coupling assembly 2 comprises an axial adjustment device 9 which is...

Abstract

A coupling assembly for optionally connecting a driving axle in a motor vehicle having multiple driving axles is disclosed. The coupling assembly comprises an externally controllable friction coupling with a coupling input part and an output part. The input part is rotatingly drivable around an axis of rotation A. A differential drive with an input element and two output elements which are drivingly connected to the input element, are also included. The input element of the differential drive is arranged coaxially relative to the coupling output part and drivably connected to the coupling output part for the purpose of transmitting torque. A driveline assembly having such a coupling assembly is also disclosed.

Description

technical field [0001] The invention relates to a coupling arrangement for coupling drive shafts in a multi-shaft drive motor vehicle. The coupling assembly comprises a first drive train (Antriebsstrang) for continuously driving the first drive shaft as well as a second drive train, which can be engaged (zuschalten) as required in order to transmit torque to the second drive shaft superior. Such a coupling assembly with an on-demand drive shaft is also referred to as a "hang-on" or "on-demand" system ("hang-on" or "on-demand" system). Background technique [0002] From EP 0 466 863 B1 is known a device for switching drive trains in a motor vehicle with a transfer gear for several drive trains. One of the drive trains is permanently connected to the drive unit, and the other drive train is connectably connectable to the drive unit. For switching on the drive train, an electronically actuatable friction coupling is provided, which can be arranged in the transfer gear or in ...
