Embodiment Construction

[0049] Features of various embodiments can also be implemented in other embodiments. So they are interchangeable.

[0050] figure 1 Schematic diagram showing the logical design of a hybrid drive train 1 consisting of two drive train sub-trains 2 , 3 which can each be connected in a torque-transmitting manner with an output shaft gear 4 . In the exemplary embodiment shown here, the output shaft gear 4 is in the form of a so-called final drive wheel 5 , which is fastened to a differential 6 . Via the differential 6 , the torque arriving there is distributed and transmitted to the wheels 7 . Power train sub 2 may also be referred to as a first power train sub 2, and in figure 1 In the exemplary embodiment shown it is driven by an internal combustion engine 8 .

[0051] This first powertrain sub-train 2 is arranged as a very short transmission on one side of a final drive plane defined by the positioning of the final drive wheels and has a number of gears (see description bel...

Abstract

The invention relates to a hybrid drive train (1), comprising a combustion engine-driveable first sub-drive train (2) and an electric motor-driveable second sub-drive train (3), wherein the first sub-drive train (2) includes a first transmission and the second sub-drive train (3) includes a second transmission designed as a planetary transmission (12), wherein torque of the first sub-drive train (2) can be transmitted to an output shaft gear (4) via the first transmission or via an intermediate gear (15) that can be friction-coupled to the first sub-drive train (2), and wherein torque of the second sub-drive train (3) can be transmitted to the output shaft gear (4) via a planetary carrier (35) of the planetary transmission (12) and the intermediate gear (15), wherein a geometric arrangement of the planetary transmission (12) is selected in such a way that the torque generated via electric motor can be supplied via a ring gear (31) of the planetary transmission (12).

Description

technical field [0001] The invention relates to a hybrid drive train having a first drive train sub-train, preferably directly drivable / directly driven by an internal combustion engine, and a second drive train sub-drive train, preferably directly drivable / directly driven by an electric motor, wherein the first A power train sub-train comprises a first transmission and a second power train sub-train comprises a second transmission designed as a planetary gear, wherein the torque of the first power train sub-train can be transferred either via the first transmission or via a combination with the first transmission. The frictionally coupled intermediate wheel of the sub-drive train is transmitted to the output shaft gear, that is, to the gear connected to the output shaft in a torque-transmitting manner, and the torque of the second power train sub-train is passed through the planets of the planetary transmission The frame and the intermediate wheel are transmitted to the output...
