<p>The invention pertains to a transmission, comprising: - an input shaft (14), on which a first cogwheel (20) is rotatably arranged; - a main shaft (18) arranged in line with the input shaft (14), on which main shaft (18) a second cogwheel (22) is rotatably arranged; - a layshaft (32), on which a first and a second gear (36) are attached, which first gear (34) is in engagement with the first cogwheel (20) and which second gear (36) is in engagement with the second cogwheel (22); - a first coupling sleeve (46) which is arranged with splines (48) on the input shaft (14), and which is axially shiftable along the input shaft (14), which first coupling sleeve (46) in a first position is arranged to, with internal teeth (49), engage with the first cogwheel (20) in order to connect the first cogwheel (20) with the input shaft (14), and which first coupling sleeve (46) in a second position is arranged to disconnect the first cogwheel (20) on the input shaft (14); and - a second coupling sleeve (50) which through internal teeth (52) is in engagement with and shiftably arranged on the second cogwheel (22), which second coupling sleeve (50) in a first position is arranged to disconnect the second cogwheel (22) from the input shaft (14), and which second coupling sleeve (50) in a second position is arranged to engage with the input shaft (14), in order to connect the second cogwheel (22) with the input shaft (14). The first and second coupling sleeves (46, 50) are arranged between the first and second cogwheels (20, 22). The invention also pertains to a gearbox comprising such a transmission, a vehicle comprising such a gearbox and a method to control a transmission.</p> |
