Embodiment Construction

[0055] In FIG. 1 , a first embodiment of a multi-stage transmission according to the invention is generally designated 10 .

[0056] The multi-stage transmission 10 is designed as an in-line transmission, that is to say a transmission for longitudinal installation in a vehicle, in particular a passenger vehicle.

[0057] The multi-speed transmission 10 has a housing generally designed to accommodate multiple components. For ease of illustration, the housing 12 shown in FIG. 1 and subsequent figures is shown in its non-separated state. The housing 12 can accommodate only the necessary functional elements of the multi-stage transmission. However, the housing 12 can also be formed as part of an adjacent housing and comprise, for example, a partition wall between the gear sets of the multi-stage transmission 10 and / or between the input-side starting and separating clutches or the like.

[0058] The multi-stage transmission 10 also has a power input shaft arrangement in the form ...

Abstract

The invention relates to a transmission (10), in particular for a vehicle, comprising: a housing (12), a drive shaft arrangement (14; 80), a driven shaft (18) and an intermediate shaft (16), a plurality of gear sets (20, 40) are installed on the driven shaft (18) or the intermediate shaft (16) and set different transmission ratios through the engagement of the corresponding shift clutches (26, 46). The intermediate shaft (16) is driven by the normal The meshing gear set (28) is connected to a driven (18), the driven shaft (18) is arranged in the housing (12) and rotates on its opposite end regions via two bearings (30, 32). At least one gear set (20, 40) is mounted in the axial region between two bearings (30, 32) of the driven shaft (18).

Description

technical field [0001] The present invention relates to a multi-stage transmission, in particular to a multi-stage transmission for vehicles, the transmission includes: a housing, a power input shaft device, a power output shaft and an intermediate shaft, wherein a plurality of gear sets are mounted on the power input shaft and on the intermediate shaft, these gear sets can be moved by means of the respective shift clutches to establish different gear stages. The end area is rotatably mounted on the housing via two bearings. Background technique [0002] A multi-stage transmission of the above-mentioned type is known from EP 1 031 765 A2. Known transmissions are so-called in-line transmissions, that is to say a transmission mounted longitudinally on the vehicle. [0003] Conventional inline transmissions of the type described typically have power input constant mesh gear sets. Power input constant mesh gear sets of the type described generally include a fixed gear fixedly...
