Embodiment Construction

[0015] figure 1 Shows a very schematic illustration of a transmission device 1 according to the invention, which contains a transmission housing 2 in which a number of different gears not shown in detail in the drawings can be arranged for obtaining a number of different gears. The component group of the transmission ratio and a starting device in the form of a torque converter. A plurality of through-holes 3 , 13 can be provided in a wall region of the transmission housing 2 , the edge region 4 of which is formed as a reinforcement zone and through which torque can be conducted from the transmission housing 2 to a formed The transmission device 1 is a power output device of a vehicle provided outside a transmission case.

[0016] The through-holes 3 are correspondingly provided in a known manner during a suitable casting production process, preferably during a die-casting production process, so that the wall region of the transmission housing 2 surrounded by the edge region ...

Abstract

The invention relates to a transmission device (1 ) comprising a transmission housing (2) wherein several components can be arranged for obtaining various translations and a starting device, preferably a hydrodynamic torque converter. Through-openings (3) can be provided in a wall area of the transmission housing (2), the edge area thereof being designed as reinforcement areas and can be guided to auxiliary drives due to the torque from the transmission housing (2). According to the invention, at least one electric machine (6) of a hybrid system is arranged in the region (5) of the transmission housing (2) that is provided for the starting device and a connection of the electric machine (6) that is arranged in the transmission housing (2), said electric machine comprising power electronics provided externally of the transmission housing (2), guided through at least one of the through-openings (3) of the transmission housing (2).

Description

technical field [0001] The invention relates to a transmission arrangement with a transmission housing of the type specified in the preamble of claim 1 . Background technique [0002] From the transmission device known in practice and preferably formed as an automatic transmission, the wall region of the transmission housing is formed in such a way that if necessary, a through hole can be machined into the wall region of the transmission housing, through which the rotary The torque is guided from the inside of the transmission housing to a power take-off arranged outside the transmission housing. In order to avoid impairing the rigidity of such a transmission housing due to the subsequent provision of through-holes, the edge regions of the through-holes are formed with stiffening regions. [0003] The reinforced region of the transmission housing of the transmission device is situated, for example, between a starting device designed as a torque converter and a plurality of ...
