Embodiment Construction

[0024] figure 1 The drive connection between an exhaust gas utilization turbine 2 and a crankshaft 3 of an internal combustion engine (not shown) according to an exemplary embodiment of the invention can be seen in FIG. The driven shaft of the exhaust gas utilization turbine is connected via a first transmission 8 to the drive wheel 4 . 1 of the hydrodynamic coupling 4 . The crankshaft 3 is connected to the driven wheel 4.2 of the hydrodynamic coupling 4 via a second transmission 9 . Accordingly, when the working chamber of the turbo coupling 4 is filled, preferably completely filled, torque or rotational power is transmitted from the exhaust gas utilization turbine 2 to the crankshaft 3 .

[0025] In order to generate a braking torque, the drive wheel 4 . 1 of the turbo coupling 4 can be braked and mechanically locked by means of the multi-plate clutch 5 . In this embodiment, the locking has two functions: first, the fluid coupling 4 is used as a reducer, that is, the crank...

Abstract

The invention relates to a drive train, comprising an internal combustion engine, an exhaust gas turbine, arranged in the exhaust system of the internal combustion engine, a crankshaft, driven by the internal combustion engine, switchably connected by means of a hydrodynamic coupling to the exhaust turbine with a drive direction such that the crankshaft is driven by the turbine, said hydrodynamic coupling comprising a primary rotor and a secondary rotor which together form a working chamber which may be filled with a working medium for torque transmission, the primary rotor being in driven connection to the exhaust turbine. The primary rotor may be mechanically braked and locked with relation to a rotational movement such that the hydrodynamic coupling assumes a hydrodynamic retarding function. Said drivetrain according to the invention is characterised in that a controller is provided which, before and / or during a braking of the primary rotor, empties the working chamber of the hydrodynamic coupling to a given level.

Description

technical field [0001] The invention relates to a drive train, in particular a motor vehicle drive train, in which the exhaust gas energy of the exhaust gas of an internal combustion engine is used for drive by means of an exhaust gas utilization turbine. Furthermore, the invention relates to a method for controlling such a drive train. Background technique [0002] In drive trains, especially in motor vehicle drive trains. The use of exhaust gas utilization turbines is known. According to a known type, the crankshaft of the internal combustion engine is additionally driven by an exhaust gas utilization turbine, which forms a suitable transmission connection with the crankshaft, during exhaust gas energy recovery operation. The drive connection includes a hydrodynamic coupling, which transmits the drive torque of the exhaust gas utilization turbine to the crankshaft. It is also possible to connect a suitable transmission or transmission in between. [0003] According to ...
