Abstract
An electric vehicle module assembly including a steering actuator sub-assembly connected to a beam axle sub-assembly. The steering actuator sub-assembly provides multiple functions, including the inherent function of the steering actuator to improve the turning radius of the electric vehicle, as well as positioning the center of gravity of the electric vehicle module assembly in a more desirable position such that NVH issues are reduced for the electric vehicle.
Claims15
An electric vehicle module assembly comprising:
- a beam axle sub-assembly;
- and
- a steering actuator sub-assembly directly connected to the beam axle sub-assembly.
A electric vehicle module assembly comprising:
- a beam axle sub-assembly including an electric motor and a wheel axle assembly defining a wheel axis;
- and
- a steering actuator sub-assembly directly connected to the beam axle sub-assembly;
- wherein the steering actuator sub-assembly is arranged on a first side of the wheel axle assembly and the electric motor is arranged on a second side of the wheel axle assembly opposite from the first side.
A method of reducing noise, vibration and harshness (NVH) in electric vehicles, the method comprising:
- connecting a steering actuator sub-assembly directly to a beam axle sub-assembly to form an electric vehicle module assembly, such that a center of gravity of the electric vehicle module assembly is shifted away from an electric motor of the beam axle sub-assembly and towards a wheel axle assembly of the beam axle sub-assembly.
