Embodiment Construction

[0034] figure 1 A schematic diagram of a motor vehicle drive train 1 according to the invention is shown, which has a transmission 2 according to the invention.

[0035] In addition to the transmission 2 , the transmission system 1 also includes a first drive unit 3 and a second drive unit 4 , the first drive unit 3 being preferably designed as an internal combustion engine and the second drive unit 4 being preferably designed as an electric machine. figure 1 The drivetrain of the is therefore a hybrid drivetrain.

[0036] The transmission 2 includes two subtransmissions 5 , 6 . The first sub-transmission 5 serves as a sub-transmission for a first drive unit 3 , which is preferably designed as an internal combustion engine, which is connectable to a first drive shaft 7 of the first sub-transmission 5 of the transmission 2 .

[0037] A damper TD may be arranged between the internal combustion engine VM and the first drive shaft 7 . The damping device TD can have a torsional ...

Abstract

The invention relates to a transmission (2) of a motor vehicle. Comprising a first drive shaft (7) for a first drive unit (3), a second drive shaft (8) for a second drive unit (4), an output shaft (9), a first sub-transmission (5) for the first drive unit (3) having the first drive shaft (7) and a countershaft (11) connected to the first drive shaft (7) by means of a constant transmission ratio, and a second sub-transmission (6) for the second drive unit (4) having the second drive shaft (8), the second sub-transmission (6) is designed as a planetary gear having a sun gear (24), a ring gear (22) and a planet carrier (23), a switching device (S3) is associated with the second drive unit (4), a first gear ratio for the second drive unit (4) being formed in a first switching position (E) of the switching device (S3), and a second gear ratio for the second drive unit (4) being formed in a second switching position (E) of the switching device (S3), a second gear ratio for a second drive unit is formed in a second switching position (F) of the switching device (S3) and at least one third gear ratio for the second drive unit is formed in a third switching position (N) of the switching device (S3).

Description

technical field [0001] The invention relates to a transmission of a motor vehicle. The invention also relates to a drive train of a motor vehicle. Background technique [0002] A transmission of a motor vehicle designed as a hybrid vehicle is known from US 2017 / 0129323 A1. The transmission has a first drive shaft and a second drive shaft, the first drive unit is connectable to the first drive shaft, and the second drive unit is connectable to the second drive shaft. Furthermore, the transmission includes a driven shaft to which the driven end is connectable. The first drive shaft is a component of the first sub-transmission for the first drive unit. The second drive shaft is a component of the second subtransmission for the second drive unit. According to US 2017 / 0129323 A1, the two partial transmissions are designed as spur gears. The two subtransmissions can be connected to each other, to be precise, via a shift element arranged on the layshaft. [0003] The transmis...
