Problems solved by technology

However, the known solutions do not take into account the phase of changing the drive through the friction clutch to direct drive and back to the friction clutch, so this is especially problematic since in this phase it is necessary to make two simultaneous changes, ie the end Direct drive and engagement clutch
This can cause considerable problems during operation of these transmissions
For these reasons, these schemes were not suitable for series use and were therefore not further pursued in practice

Embodiment Construction

[0069] figure 1 A first exemplary embodiment of a transmission 1 is shown, which in the present case has two sub-transmissions 2 and 3 , which are referred to below as first sub-transmission 2 and second sub-transmission 3 .

[0070] In showing the various shift states of the transmission 1 Figure 1 to Figure 13 In , the first sub-transmission 2 is shown in various cases at the top and the second sub-transmission 3 is shown in various cases at the bottom, but this should be regarded as purely illustrative. The two sub-transmissions 2 and 3 have respective sub-transmission shafts 4 and 5, wherein the sub-transmission shaft 4 designated by the reference sign 4 is assigned to the first sub-transmission 2 and is therefore also referred to below as the first sub-transmission The shaft 4 , while the sub-transmission shaft designated by the reference sign 5 is assigned to the second sub-transmission 3 and is therefore also referred to below as the second sub-transmission shaft 5 . ...

Abstract

The invention relates to a transmission (1) comprising at least two partial transmissions (2, 3), which have respective partial transmission shafts (4, 5) and individual gear stages (11-17, 11a-17a, 11b-17b) and can be shifted independently of each other, a friction clutch (6), an engine output shaft (7) connected to the friction clutch (6), a first transmission input shaft (9) originating from the friction clutch (6), a second transmission input shaft (10), which bypasses the friction clutch (6) and which is directly connected to the engine output shaft (7), and a transmission output shaft (8). The transmission output shaft (8) can be operatively connected to the engine output shaft (7) via at least one of the partial transmission shafts (4, 5) by means of respective form-closed, force-actuated shifting elements (19b-22b, 26, 28), which are deactivated when the actuating force is removed.

Description

technical field [0001] The invention relates to a transmission having at least two sub-transmissions which have respective sub-transmission shafts and which can be shifted independently of one another, and to a method for operating such a transmission. Background technique [0002] From the general prior art, a very wide variety of types of transmissions are known. The transmissions range from manual shift transmissions to automatic shift transmissions to dual clutch transmissions or automatic torque converter transmissions. [0003] An example of a dual clutch transmission is described in DE 198 53 824 A1. The dual clutch transmission was originally developed to provide a cost-effective alternative to automatic torque converters, which until now constituted the majority of automatic transmissions. [0004] However, dual clutch transmissions have various disadvantages, of which the high structural outlay should be mentioned first and foremost. Due to the fact that during ...
