Multi-speed transmission for a vehicle, a vehicle, and a method for operating a multi-speed transmission

A method for operating a multi-speed transmission for a vehicle, wherein the transmission has an extension in an axial direction and comprises a first input shaft, a second input shaft, a first output shaft, a second output shaft, a first intermediate shaft and a second intermediate shaft,

• wherein the transmission further comprises an annulus internally toothed first ring gear drivingly connected to the second input shaft and an annulus internally toothed second ring gear releasably connected to the first ring gear,
• wherein the first intermediate shaft comprises a first gear wheel in engagement with the first ring gear and a second gear wheel in engagement with the second ring gear, wherein the second intermediate shaft comprises a third gear wheel in engagement with the first ring gear and a fourth gear wheel in engagement with the second ring gear,
• wherein the first output shaft comprises a fifth gear wheel in engagement with the second gear wheel, and the second output shaft comprises a sixth gear wheel in engagement with the fourth gear wheel,
• wherein the first ring gear, the first gear wheel, and the third gear wheel are arranged in a first axial plane;
• wherein the second ring gear, the second gear wheel, and the fifth gear wheel are arranged in a second axial plane;
• and wherein the second ring gear, the fourth gear wheel, and the sixth gear wheel are arranged in a third axial plane;
• wherein the first ring gear and the second ring gear are releasably connected to each other via a first clutch, wherein the first gear wheel and the second gear wheel are releasably connected to each other via a second clutch arranged on the first intermediate shaft, and wherein the third gear wheel and the fourth gear wheel are releasably connected to each other via a third clutch arranged on the second intermediate shaft;
• wherein the method comprises the steps:
• operating the first clutch, the second clutch, and the third clutch between connected and disconnected modes for providing different gear ratios of the multi-speed transmission.
