Problems solved by technology

Since there is normally no hot transmission oil in the transmission housing, failure of the transmission housing usually does not lead to the escape of hot transmission oil, which in the event of a crash would pose a higher fire risk
In contrast to this, failure of the transmission housing in the region of the main housing or in the region of the end cover, if present, can lead to hot transmission oil escaping
[0005] However, it has been found that the transmission housing is only in the vicinity of a given rupture point of the transmission housing when the force introduced into the transmission housing is purposefully directed to the vicinity of the given rupture point and a stress concentration is generated at the given rupture point. zone failure

Embodiment Construction

[0024] according to figure 1 , the transmission housing 1 comprises a main housing 2 which extends in a longitudinal direction 3 . The transmission housing 1 is used to accommodate the transmission (not visible here) of a motor vehicle, which may be a passenger car in particular. The longitudinal axis 3 of the transmission housing 1 is generally defined by the axis of rotation of the drive shaft 21 and / or output shaft 22 of the transmission. At the axial ends of the main housing 2 , the transmission housing 1 has a transmission cover 4 on one side and an end cover 5 on the other side. The transmission housing 4 is flanged to the main housing 2 via a main housing-side flange 6 , for which purpose the main housing has a complementary housing-side flange 7 . In addition, the transmission housing 4 has an engine-side flange 8 via which the transmission housing 4 and thus the entire transmission housing 1 can be flanged to the engine block of the internal combustion engine of the...

Abstract

The invention relates to a housing used for transmission of motor vehicle, especially car. The housing has: a main housing used for receiving the transmission; and a transmission cover used for receiving the torque-converter of the transmission and / or the clutch of the transmission. One end of the transmission cover is connected on the main housing by a flange, the other end can be connected on the cylinder of the internal combustion engine of the vehicle by a flange; if the flange of the end cover is equipped with longitudinal ribs, the end cover is connected onto the main housing by the flange, and the longitudinal ribs are arranged on both sides of the screw holes; and if the flange of the end cover is provided with bump bridges, the bump bridges can connect the adjacent longitudinal ribs between the adjacent screw holes to each other in circumference direction; thereby, the failure properties of the transmission housing can be improved.

Description

technical field [0001] The invention relates to a transmission housing for a transmission of a motor vehicle, in particular a passenger car. Furthermore, the invention relates to a vehicle, in particular a passenger car, having a transmission with such a transmission housing. Background technique [0002] Typically, the transmission housing comprises a main housing for receiving the transmission, wherein the longitudinal direction of the main housing or of the entire transmission housing is defined by the axis of rotation of the drive shaft and / or output shaft of the transmission. At one axial end of the main housing, a transmission housing can be arranged on the main housing for receiving a torque converter of the transmission and / or a clutch of the transmission. Via the transmission cover, the transmission housing can be flanged to the engine block of the internal combustion engine of the vehicle. The main housing can have an end cap at its other axial end. [0003] In ...
