摘要

The invention relates to a drive unit (1) for an industrial truck, the drive unit (1) comprising a gear housing (2), a bearing (3) and a wheel shaft (4), the gear housing (2) comprising the bearing (3) and the Wheel shaft (4) housed, the bearing (3) comprising an inner and an outer bearing ring (6 ', 7', 6 ", 7"), the bearing (3) holding the wheel shaft (4) in the gear housing (2 ) and is designed to divert forces introduced by the wheel shaft (4) into the gear housing (2), the wheel shaft (4) being designed in accordance with a required load capacity for carrying the industrial truck, an inner diameter of the inner bearing ring (6 ') , 7 ') is designed according to a diameter of the wheel shaft (4) and wherein an inner diameter of the outer bearing ring (6 ", 7") is designed according to the inner bearing ring (6', 7 '). The drive unit (1) according to the invention is characterized in that an outer diameter of the outer bearing ring (6 ", 7") and the gear housing (2) are independent of the diameter of the wheel shaft (4) and independent of the inner diameter of the outer bearing ring (6 ') ', 7' '). The invention further relates to a corresponding modular system, a corresponding industrial truck and a corresponding method for assembling a drive unit for an industrial truck by means of a modular system.
