Hybridized double clutch transmission arrangement

A dual clutch transmission for a vehicle, comprising:

• two sets of selectable speed gear pairs,
• one or more transmission output shafts, at least one transmission output shaft being a countershaft,
• an outer transmission input shaft and an inner transmission input shaft configured to be connected to an internal combustion engine, ICE, via a dual clutch
• two sets of speed gears each set comprising a plurality of speed gear pairs,
• wherein
• in one set of speed gears, one gear of each speed gear pair is attached to the outer transmission input shaft, and
• in the other set of speed gears, one gear of each speed gear pair is attached to the inner transmission input shaft,
• the other gear of each speed gear pair being attached to the at least one countershaft, wherein torque is transferred between the outer or inner transmission input shaft and the at least one countershaft via a selected speed gear pair,
• a motor generator unit, MGU (M), connected via 0, 1 or more gear steps, to an MU torque transfer shaft, wherein:
• the torque transfer shaft on which two loose gear wheels are rotationally mounted, wherein none or either one of the two loose gear wheels can be brought into fixed rotation with the torque transfer shaft by a selector;
• one of the loose gear wheels on the torque transfer shaft is meshed via 0, 1 or more gear steps with a fixed gear wheel on one of the transmission output shafts, and
• the other loose gear wheel on the torque transfer shaft is meshed via 0, 1 or more gear steps with a fixed gear on one of the transmission input shafts
• the fixed gear wheel on one of the transmission input shaft and/or the fixed gear wheel on one of the transmission output shafts that meshes via the 0, 1 or more gear steps with the loose gear wheel on the torque transfer shaft is a gear of a speed gear pair.
