Abstract
A traction drive of a machine has an internal combustion engine, a transmission module located downstream of the engine and having an adjustable output speed, and a drive axle with a differential transmission, having a mechanical drive connection with the transmission module. The transmission module is a removable, replaceable, and interchangeable transmission module (3) which can be selected from a plurality of transmission modules (3) having different transmission types, each with a standardized input interface and a standardized output interface. A first transmission module (3) can be a hydrostatic compact transmission having a hydraulic pump (5) with an adjustable hydraulic delivery volume, and a hydraulic motor (6) in a functional hydraulic connection with the pump (5). A second transmission module (3) can be an electric compact transmission having a generator (7) and an electric motor (8) in a functional electrical connection with it.
