Embodiment Construction

[0019] The vehicle transmission 1 shown comprises a transmission housing 2 which in this example is assembled from two housing parts, namely a drive-side housing half 23 and a rear output-side housing half 24 . On the drive side, the drive-side housing half shell 23 merges into the clutch bell 3 , wherein the clutch bell 3 is embodied in one piece with the drive-side housing half 23 . In a next step, the clutch housing 19 is connected to the clutch bell 3 on the drive side. The clutch housing 19 is screwed, for example, to the clutch bell 3 . Arranged in the clutch housing 19 are the basic components of the starter clutch 6 embodied as a multi-disk clutch.

[0020] The starter clutch 6 can be driven on the drive side via a drive shaft 25 by a drive motor (not shown). The drive torque is conducted via the transmission input shaft 13 into the vehicle transmission 1 by the starter clutch 6 . In the vehicle transmission 1 , the drive torque is directed to the transmission outpu...

Abstract

The transmission (1) has a clutch bell (3) drive-laterally arranged at a transmission housing (2), and pneumatic components (4) for operating shifting elements (5) of the transmission and / or a starting clutch (6). A partition (7) is provided in the clutch bell and forms a ventilation space (8) in an interior part of the clutch bell. An outlet (9) is provided at the clutch bell and connects the ventilation space with the environment. The components are arranged in the housing such that exhaust air flows from the components into the environment through the ventilation space and the outlet.

Description

technical field [0001] The invention relates to a vehicle transmission according to the preamble of claim 1 . Background technique [0002] In particular, transmissions in drive trains of commercial vehicles often have a high number of gear stages. To achieve such a high number of gears, multi-group transmissions have proven to be advantageous. However, the high-grade positions and the structure of the multi-group speed changer also cause complicated shifting processes. Such multi-group transmissions are therefore generally designed as automatic transmissions in order to achieve a comfortable and safe driving for the driver despite complex shifting operations. In automatic transmissions, the various shifts are brought about, for example, by means of pneumatically actuated shifting devices. The shifting device is generally a pneumatic piston-cylinder unit, which is supplied with compressed gas via electronically actuatable pneumatic valves. Further elements of the automat...
