Abstract
The method for changing the gears of a manually shiftable change gear unit for commercial vehicles which has a main gear unit and fitted downstream thereof a combination of splitter gear unit and range gear unit wherein when shifting the individual gear units from the coupling position (1) to the neutral position (0), in time are first shifted the main gear unit, then the splitter gear unit and finally the range gear unit and conversely, when shifting form the neutral position (0) to the coupling position (1), in time first the range gear unit, then the splitter gear unit and finally the main gear unit are shifted.
Claims3
A method for changing the gears of a multiple gear manually shiftable change gear unit for commercial vehicles which has a main gear unit and downstream thereof a combination of splitter gear unit and range gear unit wherein the individual gear units are shifted from a coupling position (1) to a neutral position (0) in time such that first the main gear unit, thereafter the splitter gear unit and finally the range gear unit are shifted, wherein when shifting the gear units from the neutral position (0) to the coupling position (1), they are shifted in time such that first the range gear unit, then the splitter gear unit and finally the main gear unit is shifted.
The change gear unit for applying a method for changing the gears of a multiple gear manually shiftable change gear unit for commercial vehicles which has a main gear unit and downstream thereof a combination of splitter gear unit and range gear unit wherein the individual gear units are shifted from a coupling position (1) to a neutral position (0) in time such that first the main gear unit, thereafter the splitter gear unit and finally the range gear unit are shifted, wherein when shifting the gear units from the neutral position (0) to the coupling position (1), they are shifted in time such that first the range gear unit, then the splitter gear unit and finally the main gear unit is shifted, having a combination of splitter gear unit and range gear unit is located downstream in a direction of power transmission of a multiple gear main gear unit.
