The invention relates to a drive unit, preferably for a motor vehicle, according to the preamble of patent claim 1.
It is a dual-clutch transmission for a motor vehicle, in particular with a hybrid drive known, WO 2007/042109 Al. The dual-clutch transmission includes two clutches and two transmission input shafts, each with a drive shaft assigned to it. The drive shafts are part of two parallel transmissions with different gear ratios. Between the clutches and the gears an electric machine is provided, which is effective as an electric motor and / or generator and connectable to the transmission input shafts. And the electric machine is coupled via an additional transmission with the first and the second transmission input. The additional gear is designed as a planetary gear.
The US 7,150,698 B2 deals with a drive system for a motor vehicle, in which an internal combustion engine interacts with a transmission unit. In this case, an output shaft of the internal combustion engine influenced by the intermediary of a spur gears having a first gear input shaft and a second input shaft. Switchable clutches are effective between the first input shaft and the second input shaft and spur gears of the transmission. And in the input shafts electric motors are switched, with extension times are after the electric motors with manual transmissions in operative connection. By means of the manual transmission power is transmitted to drive wheels of the motor vehicle.
The object of the invention is conceive a drive unit for a motor vehicle, which includes an internal combustion engine, a clutch, a transmission system and a planetary gear to make so that it is characterized by compact design and good function. It should be feasible with the planetary gear in conjunction with an electric motor and the transmission system several technical tasks of the drive unit.
According to the invention, this object is solved by the features of patent claim 1. Further features embodying the invention are contained in the subclaims. 2
The advantages achieved by the invention are to be seen in the fact that the planetary gear with the first and the second planetary gear, mounted on the common planet carrier, easily with reasonable space requirement in the drive unit is integrable. In this case, the first planetary gear set and the second planetary gear set interact in an exemplary manner with the first drive element of the clutch and the second drive element of the planetary gear, which, for example, influences the electric motor. The implementation of the planetary gear is facilitated by the fact that the first planetary gears of the first planetary gear are on the first circumference whose first diameter is smaller than the second diameter of the second circumference, on which the second planetary gears of the second planetary are arranged, It should be emphasized that the 'first planet gears on the one hand with the sun gear of the planetary gear and on the other hand with the second planetary gears mesh, soft second planet gears selectively meshed with the first planetary gears and the other with the ring gear of the planetary gear. A scale setting design of the drive unit is achieved in that the ring gear is surrounded by the electric motor, which acts in conjunction with the planetary gear, for example, as a generator, starter, synchronizer and power booster. The use of double-clutch, comprising the output shaft system with the inner output shaft and the outer output shaft, it allows little effort to connect the sun gear with the inner output shaft and the planet carrier with the outer output shaft. Arrangement, training and design of the dual clutch and the planetary gear with first and second
Pianetenradsatz ensure a functional synchronization of the gear shafts of the two partial transmission of the dual clutch transmission safely. And in addition, it is also achieved: • A reversal of rotation -Nulldurchgang the speed of the electric motor is avoided, • The speed spread of the electric motor is reduced, meaning the speed difference of the electric motor -Start to end synchronization is between the speed difference between the two to be synchronized transmission shafts, 3 • The electric motor always turns in the same direction, and it works by motor or generator. As a result, rotationally defined components, such as e.g. Air compressor on the drive unit with the electric motor coupled.
In the drawing, an embodiment of the invention is shown, which will be explained in more detail below.

And the second Pianetenräder 14 of the second planetary gear set 10 work on the one with the first Pianetenräder 13 together and, on the other hand, they mesh with a ring gear 16 of the planetary gear 8 that includes an internal toothing. The ring gear 16 of the planetary gear 8 is surrounded by an electric motor 17. A rotor 18 of the electric motor 17 is rotatably connected to the ring gear 16 of the planetary gear 8.
The transmission system 6 is designed as Doppelkuppiungsgetriebe 19, in addition to a dual clutch 20, a first partial transmission 21 with a first transmission shaft 22 and a second Teflgetriebe 23 with a second transmission shaft 24. The GetriebeweElen 22 and 24 carry gears for different switchable gears of the dual clutch transmission 19th
The dual clutch 20 has a first inner output shaft 25 and a second outer output shaft 26 surrounding the first inner output shaft 25. The first inner output shaft 25 carries the sun gear 15 of the planetary gear 8, which sun gear 15 is in operative connection with the first planet gears 13. The first Pianetenräder 13 and the second Pianetenräder 14 rotate about bearing journals 28 and 29 of a Pianetenträgers 30 of the planetary gear. 8
