Problems solved by technology

In this type of hybrid powertrain, generally only one or two forward gears are implemented, as the electric motor is capable of starting from rest (0 rpm (revolutions per minute)) and is capable of delivering high Setting a large number of gears is redundant

Embodiment Construction

[0062] exist figure 1 , a first embodiment of a hybrid powertrain is schematically illustrated in longitudinal section and generally designated with reference numeral 10 . The hybrid powertrain 10 is suitable for installation in a motor vehicle 11 , in particular in a front-mounted transverse arrangement.

[0063] The hybrid powertrain 10 includes an internal combustion engine 12 having a crankshaft 14 . Crankshaft 14 is connected to a dual clutch transmission 20 via a first clutch 16 , and optionally via a dual mass flywheel 18 .

[0064] The dual clutch transmission 20 includes a dual clutch arrangement 22 having an input element 23 connected to an output element of the first clutch 16 . Furthermore, the dual clutch device 22 has a second clutch 24 and a third clutch 26 .

[0065] The dual clutch transmission 20 also includes a spur gear transmission 28 comprising a first partial transmission 30 and a second partial transmission 32 .

Abstract

Hybrid drive train for a motor vehicle, comprising an internal combustion engine, an electric machine and a dual clutch transmission. The transmission has a dual clutch arrangement and a spur gear transmission arrangement with two part-transmissions. The spur gear transmission arrangement is configured to set exactly three forward gear stages, or is configured to set exactly four forward gear stages. The spur gear transmission arrangement being configured with three parallel shaft arrangements which are connected to one another via gear set arrangements in such a way that motive power is transmitted via at least two of the shaft arrangements, depending on the forward gear stage engaged.

Description

technical field [0001] The invention relates to a hybrid drive train for a motor vehicle comprising an internal combustion engine, an electric machine and a dual clutch transmission comprising a dual clutch and a spur gear transmission with two partial transmissions. Background technique [0002] Hybrid drive trains of this type are known, for example, from the documents DE 10 2011 110 444 A1 or DE 10 2011 102 267 A1. [0003] In the case of hybrid transmissions, a distinction is generally made between the case where the motive force is mainly provided by the internal combustion engine and the electric machine is used as an auxiliary unit. Such drive trains generally have a largely conventional layout, with both the internal combustion engine and the electric machine generally arranged upstream of the input to the clutch arrangement. Currently commonly used dual-clutch transmissions used in such hybrid powertrains have five, six, seven or more forward gear stages, and are t...
