A wheel mechanism is disclosed for a vehicle which has a wheel support, such as an axle, in which an electric motor is housed having a drive shaft within a hub. A wheel is journaled on bearings around the hub and an axially outboard wall cooperates with the hub to form a gear case. Within the gear case, first and second planetary gear sets are connected to drive the wheel from the motor drive shaft. The axially outboard wall on the gear case is nonrotating and supports brake calipers to cooperate with a disc brake secured to the wheel. A modular construction of the entire wheel mechanism is provided, with the brake being outboard for easy servicing of brake pads and the planetary gear sets being next outboard for any service or gear ratio change required. The foregoing abstract is merely a resume of one general application, is not a complete discussion of all principles of operation or applications, and is not to be construed as a limitation on the scope of the claimed subject matter.

A vehicle wheel mechanism for a vehicle having a wheel support, comprising in combination, a nonrotating wheel hub connected to the wheel support, a hollow gear case connected to said hub, a nonrotating, axially outboard wall defining with said hub a part of said gear case, a rotatable drive shaft in said gear case, a wheel, bearing means journaling said wheel on said hub, a planetary gear set mounted in said gear case and having an input and an output, drive means operably connecting said input to said drive shaft, means connecting said output to said wheel for drive thereof, a rotatable first brake part secured to said wheel outboard of said gear case outboard wall, and a nonrotatable second brake part secured to said gear case outboard wall at a location remote from the axis of the wheel and acting on said first brake part.
