Abstract: A method for producing a stator (20) of an electric machine is provided. The method includes providing a stator (20) with at least one stator slot (22) that is bounded by two stator teeth. The method proceeds by introducing electrical conductors (30) into the at least one stator slot (22). At least one conductor (30) has an expandable coating (25) applied partially to its surface. The method continues by activating the expandable coating (25) to bring about an expansion of the coating (25), as a result of which the conductors (30) are fixed within the stator slot (22).

Abstract: An oil catching device and an oil pump for an internal-combustion engine are provided, having an oil catching housing which is arranged below a crankcase and which has at least two oil collecting spaces, in a first oil collecting space an oil pump being arranged which has two pump stages, at whose two suction stages one oil suction pipe, respectively, is connected. The first oil suction pipe reaches in the first oil collecting space in order to deliver the lubricating oil by way of the delivery side of the first pump stage to the consuming devices, and the second oil suction pipe connected with the second suction stage leads to a second oil collecting space. On its top side, the housing of the oil pump has an opening connected with the delivery side of the second pump stage, by way of which opening, the oil suctioned out of the second oil collecting space is delivered into the first oil collecting space. This achieves a defoaming of the suctioned-off lubricating oil.

Abstract: A planetary transmission having a centrifugal brake is connected into a vehicle drive line and, when there is a rotational speed difference between an input shaft and an output shaft, transmits torque to the output shaft. Due to a special mounting of the input shaft and the output shaft of the planetary transmission, the occurring forces and torques are transmitted effectively, in which the case the parts of the planetary transmission can be manufactured in a cost-effective way and are easy to assemble.
