Abstract
The present disclosure provides a front axle of a vehicle including a motor disposed near the center of the axle and a shaft coupled at one end thereof to the motor, where the shaft defines a first axis. A first gear is coupled to a second gear, the first gear being coupled to the shaft at an end opposite the motor and being disposed along the first axis. The second gear is disposed along a second axis, where the first axis and second axis are substantially parallel to but spaced from one another. A steering pivot defines a steering axis about which a final drive assembly pivots and a wheel lean pivot defines a lean axis about which the final drive pivots. The lean axis is substantially perpendicular to the steering axis. A constant-velocity joint is disposed at the intersection of the steering axis and lean axis.
