Document Type and Number:
WIPO Patent Application WO/2013/083738
Kind Code:
A3
Abstract:
The invention relates to a motor vehicle drive train including a driving engine and driven wheels which are driven by the driving engine via a main branch. The drive train further includes a hydrodynamic retarder comprising a revolving rotor and a stator or a revolving rotor and a counter-rotating twin rotor which jointly form a working chamber that is or can be filled with a working medium. The drive train also includes a disconnect clutch which allows the rotor of the hydrodynamic retarder to be disengaged from a driving power flow in the drive train. The invention is characterized in that the hydrodynamic retarder is connected to the main branch via an at least two-stage transmission comprising at least one intermediate shaft and a rotor shaft which drives or supports the rotor, the intermediate shaft forming at least one first transmission stage along with the main branch while forming at least one second transmission stage along with the rotor shaft. Furthermore, the disconnect clutch is arranged on the intermediate shaft.
