Abstract
An electrically driven axle assembly is disclosed. In various embodiments, the electrically driven axle assembly includes a main housing; a differential plate configured for mounting within the main housing; a differential assembly, the differential assembly disposed adjacent the differential plate and having a bearing configured for mounting within a plate orifice that extends within the differential plate; a first drive shaft having a first inboard end connected to the differential assembly and a first outboard end configured to receive a first wheel; a first electric machine configured to drive the differential assembly; and a first gear assembly configured to operably couple the first electric machine to the differential assembly.
Claims11
An electrically driven axle assembly, e-axle, for a vehicle, comprising:
- a main housing defining an inner space;
- a differential plate configured for mounting within said inner space fixedly to said main housing, said differential plate defining a through opening;
- a differential assembly, said differential assembly being disposed adjacent to said differential plate and being rotatably supported over said differential plate;
- a first drive shaft having a first inboard end connected to said differential assembly and a first outboard end configured to receive a first wheel of said vehicle;
- a second drive shaft having a second inboard end connected to said differential assembly and a second outboard end configured to receive a second wheel of said vehicle;
- at least one electric machine configured to drive said differential assembly;
- and
- a mechanical transmission housed within said inner space and operatively connected between said at least one electric machine and said differential assembly;
- wherein the main housing includes a housing case and a cover plate realized as a separate element and fixedly mounted to said housing case;
- wherein said differential plate defines a first side and a second side opposite to the first side, said differential plate defining a plurality of abutments configured to cooperate by contact with said cover plate and to allow the mounting of said differential plate to said cover plate.
