Embodiment Construction

[0087] exist Figures 1 to 4 In each case only the upper half of the drive train module is shown in side view.

[0088] figure 1 A known drive train module for a commercial vehicle is shown. The centerline of the crankshaft is shown with a dotted line M. exist figure 1 Only part of the crankshaft 1 is visible in the figure, in particular the crankshaft bearing 3 , the crank pin 2 for receiving the connecting rod, the flange area 4 and the gear wheel 5 . Via gear 5 , the camshafts can be actuated with defined transmission ratios.

[0089] A cup-shaped flywheel 14 is connected to the crankshaft 1 . The flywheel 14 includes a hollow-cylindrical outer edge region 14 a which extends on the transmission side and on which the annular rotor 6 of the crank-starter generator is arranged in a rotationally fixed manner. The transmission on the output side is not shown, which is in the figure 1 The center is arranged on the left of the drive train module 10 .

Abstract

The invention relates to a drive train module for a motor vehicle, comprising a to the crankshaft (1) connected to said flywheel (24); one connected to the crankshaft (1) operatively connected to a crankshaft starter generator, comprising a rotor (6) and a stator (7); a flywheel (24) arranged ring gear (25) and an electric starter motor (19a) with a starter pinion (19) which is engaged to rotate the ring gear with this can be brought and / or is engaged, wherein the starter pinion in a radial direction, perpendicular to the crankshaft axis (M) is offset with respect to the rotor (6) and / or the stator (7) is arranged the crankshaft starter generator.

Description

technical field [0001] The invention relates to a drive train module for a motor vehicle, in particular an assembly consisting of a flywheel and a crankshaft starter generator. Background technique [0002] In order to enable the first mixture formation, ignition and combustion in the internal combustion engine, the internal combustion engine is brought to a defined minimum rotational speed by an external force source. For this purpose, drive train modules are known from the prior art in which an electric crank-starter generator (KSG) is arranged between the engine and the transmission. This is an electric motor with starter and generator functions on the crankshaft, which is often referred to as a crankshaft-starter generator because its rotor is directly coupled to the crankshaft of the internal combustion engine. [0003] The KSG rotor is connected to the flywheel arranged on the crankshaft. In this way it is in operative connection with the crankshaft. The connected a...
