A gearing unit for a drive assembly includes a gearing device for converting a drive torque of the drive assembly. The gearing device includes an input shaft, and the input shaft defines a main axis. A gearing housing defines an accommodation space and houses the gearing device in the accommodation space. A venting device is mounted on the gearing housing and extends through the gearing housing to the accommodation space. The venting device is arranged coaxially with the main axis and on an axial end face of the input shaft.

Gearing unit for a drive assembly and method for mounting the gearing unit

An electrically operable drive train of a motor vehicle, including an electric motor and a transmission arrangement, in which drive train the electric motor and the transmission arrangement form a structural unit, and the structural unit includes a first housing part and a second housing part, the first housing part and/or the second housing part having fastening means which bring about predefined positioning of the first housing part relative to the second housing part, and the first housing part is formed from a metal material, the second housing part being shaped from a plastics material by means of primary shaping processes, in particular by means of an injection moulding process, and having at least one insert part which is surrounded by plastics material in such a way that it is arranged in the second housing part such that it transmits axial and/or radial force and/or torque.

Electrically operable drive train

During operation of a wet-running gearbox, vapours and/or air can arise in a housing of the gearbox, which can increase an internal pressure in the housing and thus can influence the operating safety of the gearbox. The problem addressed by the invention is that of creating a gearing unit, which is distinguished by an advantageous arrangement of a venting device. To this end, a gearing unitfor a drive assembly is specified having: a gearing devicefor converting a drive torque of the drive assembly, the gearing devicehaving an input shaft, and the input shaftdefining a main axis H; a gearing housingfor accommodating the gearing device, the gearing housingdefining an accommodation spacefor the gearing device; and a venting devicefor venting the accommodation space, the venting devicebeing mounted on the gearing housing, wherein the venting deviceis arranged coaxially with the main axis H and on an axial end face of the input shaft
