Problems solved by technology

For example, the outer radius of the motor is limited by the clearance of the axle above the ground
Thus, the moment arm of the motor is limited by the outer radius of the motor, which affects the maximum torque that can be produced by the motor
[0004] As another example, the coaxial arrangement of the motors results in a relatively large number of drive train components, which increases the complexity of the assembly
Large numbers of components are relatively more difficult to maintain and repair than smaller numbers

Abstract

The present invention relates to an axially offset motor. A vehicle is provided. The vehicle comprises an axle having a longitudinal dimension along a first axis, the axle coupled to at least one wheel, and a motor coupled to the axle and adapted to turn the axle, the motor adapted to rotate around a second axis, wherein the motor is oriented such that the first axis is substantially perpendicular to the second axis.

Description

technical field [0001] Embodiments of the subject matter described herein relate generally to electric motors for vehicles. More specifically, embodiments of the subject matter relate to the positioning of axial motors for vehicles. Background technique [0002] Vehicles, including electric vehicles and hybrid electric vehicles, typically use motors to rotate an axle coupled to two wheels for travel. The motor is usually coaxial with the axle. Electric power is typically used to spin the motor's rotor, which in turn spins the axle. Rotation of the axle causes the wheels to rotate, which in turn propels the vehicle in the desired direction. [0003] Motors coaxial with the axles that turn the vehicle's wheels have inherent limitations. For example, the outer radius of the motor is limited by the clearance of the axle above the ground. Thus, the torque arm of the motor is limited by the outer radius of the motor, which affects the maximum torque that can be produced by th...
