Embodiment Construction

[0024] figure 1 A perspective sectional view of a transmission for an automobile.

[0025] The transmission has a housing 1 comprising a first housing part 10 and a second housing part 20 . The housing 1 encloses an interior 2 of the transmission, in which an input shaft 3 , a countershaft 4 and an output shaft 5 are rotatably mounted. The input shaft 3 is arranged coaxially with the output shaft 5, so figure 1 The transmission shown is an inline transmission.

[0026] In the interior 2 there is (transmission) oil, which is centrifugally separated by the rotation of the shafts 3 , 4 , 5 in the interior 2 and the gears arranged thereon. If an increase in temperature occurs in the interior 2 of the transmission, the air in the cavity 2 expands, causing a pressure increase in the transmission. In order to suppress this pressurization, the transmission has an exhaust duct 30 which is formed in the second housing part 20 . figure 1 The exhaust hose 6 can be seen in the figure,...

Abstract

The invention relates to a transmission for a motor vehicle, the transmission having a housing (1), which has a first housing part (10) and a second housing part (20), wherein, in the assembled stateof the transmission, the first housing part (10) and the second housing part (20) are joined together, having a vent duct (30), through which air can escape from the transmission, and having a separate breather element (31), which extends into the first housing part (10) and forms at least one first duct wall of the vent duct (30). The invention is characterized in that the breather element (31) is located in a plug-in position in the first housing half (10) and has a fixing stop (37), against which the second housing part (20) bears in the assembled state of the transmission and thus securelyfixes the breather element (31) in the plug-in position.

Description

technical field [0001] The invention relates to a transmission for a motor vehicle having a housing and an exhaust duct via which air can escape from an interior of the transmission enclosed by the housing. Background technique [0002] DE 10 2014 215 203 A1 discloses an exhaust element for a vehicle transmission which forms an exhaust duct or at least a first channel wall of the exhaust duct. The vehicle transmission has a first housing part and a second housing part, wherein in the installed state of the transmission the first housing part and the second housing part abut against each other and are fixedly connected. The split exhaust element has holding means for fastening the exhaust element to the first housing part. A special installation step is required to fix the exhaust element on the first housing part, which increases the installation costs of the transmission. [0003] The split venting element extends from the first housing part via the dividing line between ...
