Abstract
An electric drive module comprises a housing, at least one electric motor attached to the housing, a main gear wheel mechanically connected to the electric motor by mechanical gears, a gearbox, where the gearbox input member is driven by the main gear wheel, an axle differential housed in an axle differential housing and driven by an gearbox output, and drive shafts driven by the axle differential, the axis of which is parallel to the axis of the gearbox. At least a portion of the differential housing is rigidly connected to the output member of the gearbox, which allows direct connection of the gearbox and the differential.
Claims16
An electric drive module for driving an axle comprising a housing, at least one electric motor attached to the housing, a main gear wheel mechanically connected to the at least one electric motor via mechanical gears, a gearbox designed as a planetary gearbox, wherein it comprises a sun gear torisonally rigidly connected to the main gear wheel, planet gears, and a ring gear, wherein an input member of the gearbox is driven by the main gear wheel, an axle differential located in an axle differential housing and driven by a gearbox output, drive shafts driven by the axle differential, wherein an axis of the drive shafts is parallel to an axis of the gearbox, wherein at least part of the differential housing is rigidly connected to the output member of the gearbox, wherein the ring gear is pivotally housed on the at least part of the differential housing part on a main gear wheel side by a ring gear bearing.
