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 power train (1) having a first power train sub-train (2) drivable by an internal combustion engine and a second power train sub-train (3) drivable by an electric motor, wherein the first The sub-power train (2) includes a first transmission, and the second sub-power train (3) includes a second transmission configured as a planetary transmission (12), wherein the first sub-power train (2) The torque can be transmitted to the output shaft gear (4) either through the first transmission or through the intermediate wheel (15) frictionally coupled with the first power transmission sub-train (2), and wherein the second The torque of the sub-power transmission system (3) can be transmitted to the output shaft gear (4) through the planet carrier (35) and the intermediate wheel (15) of the planetary transmission mechanism (12), wherein the planetary transmission mechanism (12) The geometrical arrangement of is selected such that the torque generated by the electric motor can be transmitted via the ring gear (31) of the planetary gear (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...
