Abstract: 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 unit 1 for a drive assembly is specified having: a gearing device 4 for converting a drive torque of the drive assembly, the gearing device 4 having an input shaft 8, and the input shaft 8 defining a main axis H; a gearing housing 2 for accommodating the gearing device 4, the gearing housing 2 defining an accommodation space 3 for the gearing device 4; and a venting device 10 for venting the accommodation space 3, the venting device 10 being mounted on the gearing housing 2, wherein the venting device 10 is arranged coaxially with the main axis H and on an axial end face of the input shaft 8.

Abstract: A method for determining a switching point of a solenoid valve. A solenoid coil is energized to raise a solenoid armature to unblock a flow opening. For a signal profile characteristic of a current profile in the solenoid coil, multiple periods each different from one another and each having the same predefined temporal length are determined. Within each period, a minimal and a maximal value of the signal profile and associated points in time are ascertained and a product of a difference between the maximal and minimal value and a difference between the associated points in time are ascertained. On the basis of the points in time of the minimal and maximal value of that period, which corresponds to a maximal value of the product, the switching point is determined.

Abstract: 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.
