Abstract: A tool kit for assembling a transmission shaft arrangement with a transmission housing includes a guiding part defining a guiding path extending along an exterior of the guiding part from a start position to an end position, the guiding part being configured to be positioned with the end position within the transmission housing. The tool kit further includes an engagement member configured to be fixed to a component of the transmission shaft arrangement, wherein the engagement member is configured to slidingly engage with the guiding part and slide along the guiding path from the start position to the end position. The guiding path is arranged to guide the transmission shaft arrangement such that it is translated and rotated with respect to the guiding part as the engagement member is slid along the guiding path from the start position to the end position.

Abstract: The method for monitoring the wear of a powertrain includes an analysis cycle that includes, in this order, preventing mechanical components from moving; rotating an electric motor in a first direction until a torque value delivered by the electric motor reaches a predetermined threshold, a first angular position of the electric motor being reached; rotating the electric motor in a second direction opposite to the first direction until a torque value delivered by the electric motor reaches the predetermined threshold, a second angular position of the electric motor being reached; and calculating a backlash value of the powertrain on the basis of the first and second angular positions. The method further includes comparing the backlash value calculated during the analysis cycle to a reference value to monitor wear of the powertrain.

Abstract: A method of oil pre-conditioning for an electric powertrain for a vehicle configured to provide electric propulsion of the vehicle, said electric powertrain comprising the first electric motor being linked to the first gear module, a secondary shaft being linked to the second gear module, the second electric motor being linked to the third gear module through a motor shaft, the differential being shared by both electric motors, The electric powertrain is surrounded by an oil. The method includes the steps of selecting an oil pre-conditioning configuration wherein the secondary shaft does not rotate and at least one of the first electric motor or the second electric motor rotates while the other is in driving mode leading to the heating of the oil to reach a threshold temperature and applying the selected oil pre-conditioning configuration.
