Problems solved by technology

Due to this design as a separate module, it requires additional bearings and seals for the rotating parts, which significantly increases the construction space requirement
In addition, in the separate clutch modules, due to the central pressure medium conduction, an undesired drag torque occurs, which increases the power loss and also heats up the clutch

Embodiment Construction

[0026] A number of different embodiment variants of a hybrid drive train for a vehicle according to the invention are shown in the drawings. Regardless of the respective embodiment variant, the hybrid drive train contains an internal combustion engine for internal combustion engine driving and at least one electric machine 1 for electric driving as well as a dual clutch transmission with dual clutch 2 . The electric machine 1 can be disconnected from the internal combustion engine via a separating clutch 3 , which is designed as a wet-running, hydraulically actuated plate clutch.

[0027] According to the invention it is provided that the outer disc carrier 4 of the separating clutch 3 is connected to the outer disc carrier 5 , 5A of the dual clutch 2 of the dual clutch transmission, which is designed as a disc clutch, and is jointly mounted on the transmission housing 6 . In this way, the combination of the split clutch and the outer disc carrier of the dual clutch is realize...

Abstract

The invention relates to a hybrid drive arrangement for a vehicle with an internal combustion engine for driving, under engine power, at least one electric machine (1), for electric driving, and with a double-clutch transmission. The electric machine (1) can be separated from the internal combustion engine by at least one separator clutch (3), in the form of a wet-operating, hydraulically actuated disk clutch. The outer disk carrier (4) of the separator clutch (3) and the outer disk carriers (5, 5A) of the two double clutches, of the double-clutch transmission, are connected and mounted on the transmission housing (6).

Description

technical field [0001] The invention relates to a hybrid drive train for a vehicle of the type defined in the preamble of claim 1 . Background technique [0002] Hybrid drive trains for vehicles are known from vehicle technology which contain an internal combustion engine for internal combustion engine driving and an electric machine for electric driving as well as a transmission. In particular in parallel hybrid systems a separating clutch is required between the electric machine and the internal combustion engine in order to be able to disconnect the internal combustion engine during electric driving. The separation clutch can be designed as a dry disc clutch or a wet disc clutch. In hybrid modules with a dry-running (lubricated-running) electric machine, the wet disc clutch is designed as a closed module as a separating clutch. Due to this design as a separate module, it requires additional bearings and seals for the rotating parts, which significantly increases the con...
