  • Driveline for mobile vehicles
    Patent number: 6890282
    Abstract: A driveline for a mobile vehicle comprises a one-step planetary transmission (7) in which the outer central wheel (10) is non-rotatably held, the inner central wheel (6) forms the output and the planet carrier (12) forms the output which can be connected with the housing (4) via a brake (14). To ensure an easy assembly, the output flange (17) is supported in the housing (4) via a first bearing (28) and the planet carrier (12) via a second bearing (26), one pivot (24) of the planet carrier (12) is non-rotatably held in one hole of the output flange (17).
