Differential gearbox with variable torque distribution between vehicle drive shafts has dual planetary gearbox with stage with 2 sets of planetary gears, hollow wheel, sun wheel connected to differential cage, first/second driven shafts

摘要

The differential gearbox has a dual planetary gearbox with a stage (15) with two sets of planetary gears (19,21), a hollow wheel (12) and a sun wheel (16), one each of these elements (15,12,16) being connected to the differential cage (11), a first driven shaft and a second driven shaft respectively. At least one filling body (14) at least substantially fills the gaps between the gear wheels in the tooth engagement regions. An external hydraulic machine is connected to first and second channels of a chamber system.
