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] Figures 1 to 12 are first described together in view of their commonality. The coupling assembly 2 is shown respectively, and the coupling assembly 2 is used to connect the drive shaft to the longitudinal drive shaft of the motor vehicle or disconnect the drive shaft from the longitudinal drive shaft of the motor vehicle and adjust the action on the drive shaft as required Torque distribution. As an assembly, the coupling assembly 2 includes a friction coupling 3 and a differential transmission 4, which are connected in series in terms of torque flow. Among them, a switching coupling can also be provided between the friction coupling 3 and the differential transmission 4 41.

[0047] The friction coupling 3 includes a coupling input part 6 and a coupling output part 8. The coupling input part 6 is firmly connected with a crown gear (Tellerrad) 7 for introducing torque into the coupling assembly 2. The coupling The output member 8 is used to drive the differential transmi...

Abstract

The invention relates to a clutch arrangement for engaging a drive axle in a multi-axle driven motor vehicle. The clutch arrangement comprises an externally controllable friction clutch 3 having a clutch input part 6 that can be rotationally driven by a rotary axis A, and having a clutch output part 8; and a differential gearbox 4 having an input element 15 and two output elements drivingly connected to the input element 15, wherein the input element 15 of the differential gearbox 3 is disposed coaxially to the clutch output part 8 and can be drivingly connected to the clutch output part 8 for transferring a torque. The invention further relates to a drivetrain arrangement having such a clutch arrangement.

Description

Technical field [0001] The invention relates to a coupling assembly for connecting a drive shaft in a motor vehicle with a multi-shaft transmission (mehrachsgetrieben). The coupling assembly includes a first drive train (Antriebsstrang) for continuously driving the first drive shaft and a second drive train, which can be switched on (zuschalten) when needed, in order to transmit torque to the second drive shaft on. Such a coupling assembly with a drive shaft that can be switched on when needed is also referred to as a "Hang-on" or "On-demand"-System. Background technique [0002] From document EP 0 466 863 B1, a device for switching on the drive train in a motor vehicle with a transfer gear for multiple drive trains is known. One of the drive trains is constantly connected with the drive unit, and the other drive train can be connected with the drive unit in a connectable manner. In order to switch on the drive train, an electronically steerable friction coupling is provided, ...
