Abstract

A split circumference wheel assembly is provided for an aircraft landing gear wheel configured to maximize the space available within a landing gear wheel well to support a motor driver assembly with drive means that drives the aircraft wheel on the ground. The split circumference wheel assembly includes separable inboard and outboard support walls that are spaced axially apart a maximized distance so that the motor driver assembly is completely contained within the maximized space defined. A preferred wheel assembly employs a demountable flange and a locking ring to integrally and removably support the motor driver assembly within the maximized wheel volume to drive one or more aircraft wheels and move the aircraft independently on the ground. The wheel and motor driver assembly described herein are designed to be retrofitted in an existing aircraft wheel.
